To move or not to move: is it cheaper to find a new place or stay when your rent increases by 10%?

<p><em><a href="https://theconversation.com/profiles/park-thaichon-175182">Park Thaichon</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> and <a href="https://theconversation.com/profiles/sara-quach-175976">Sara Quach</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p>Your landlord has just raised your rent by 10% and your mind starts running the numbers – should you cop it sweet or look to move?</p> <p>It’s a familiar scenario in today’s unpredictable housing market.</p> <p>Understanding the real costs of staying versus moving is essential for making informed choices: renters must consider hidden expenses such as moving costs, deposits and changing rental rates, giving them tools to handle rising rent pressures more effectively.</p> <h2>A grim time for many renters</h2> <p>National median market rents have hit record highs, reaching $627 per week, with an average annual growth rate of 9.1% during the past three years, according to real estate giant <a href="https://www.aph.gov.au/About_Parliament/Parliamentary_departments/Parliamentary_Library/Budget/reviews/2024-25/Housing#:%7E:text=Based%20on%20April%202024%20CoreLogic,the%20past%203%20calendar%20years">CoreLogic</a>.</p> <p><a href="https://www.corelogic.com.au/news-research/news/2024/rent-growth-picked-up-in-the-start-of-2024,-taking-rents-to-new-record-highs">CoreLogic</a> also reported annual rental changes (houses and units) in regional Australia are not far off from the big cities: annual rent changes were 9.4% for combined capital cities, 6.4% for combined regional areas, and 8.5% nationally.</p> <p>So, is it better to stay or move if your rent is raised by 10%? Let’s examine the costs and benefits of each option.</p> <h2>A breakdown of typical moving costs</h2> <p>We’ll start with the most obvious expense: <strong>moving costs</strong>.</p> <p>Professional moving services aren’t cheap. For example, moving a three-bedroom house in the Gold Coast costs <a href="https://www.muval.com.au/removalists/gold-coast">$1,095.25 on average</a>, with an hourly rate of $158.26.</p> <p>In a bigger city like Melbourne, the cost is slightly higher at <a href="https://www.muval.com.au/removalists/melbourne">about $1,118.46</a>.</p> <p>The moving costs between states or cities will be more expensive if you move further away.</p> <p>You could choose to handle packing yourself and hire some help with a truck – a common option with businesses such as “<a href="https://www.gumtree.com.au/s-removals-storage/gold-coast/2+men+and+a+truck/k0c18643l3006035">Two Men and a Truck</a>”, which typically costs around $100 per hour.</p> <p>Be aware, though, that the hourly rate often starts from the moment the truck leaves the company’s warehouse until it returns. Alternatively, you can rent a van for a lower price, such as $87 for a 24-hour <a href="https://www.bunnings.com.au/for-hire-handivan-24hr-first-100kms-inc-_p5470402">Handivan rental at Bunnings</a>.</p> <p>Don’t forget the cost of moving boxes, too: Bunnings’ 52 litre <a href="https://www.bunnings.com.au/bunnings-52l-light-duty-moving-carton_p0517130?srsltid=AfmBOoqCYAWT0P5apPiJpoOLRAIpUCHNi63ztvIZrG5CxCoNOv45G0TV">moving cartons</a> cost $2.66 each.</p> <p>End-of-lease or <a href="https://firstcallhomeservices.com.au/service-menu/bond-exit-end-lease-cleaning/"><strong>bond cleaning</strong></a> is another common expense.</p> <p>For a typical three-bedroom property, internal cleaning can range from $365 to $500.</p> <p>If you have pets, or kids who love drawing on the walls, your cleaning costs might be a bit higher.</p> <p>Now, let’s look at <strong>utility connection expenses</strong> that can catch people by surprise.</p> <p>Cancelling your internet service can be costly if you don’t meet the exit or cancellation policies. With <a href="https://www.telstra.com.au/internet/5g-home-internet">Telstra Home Internet</a>, for example, if you cancel within the first 24 months, you must return your modem within 21 days to avoid a $400 non-return fee.</p> <p>Most providers charge a cancellation fee or require final device repayments, typically ranging from $100 to $500, depending on the remaining contract period. As a renter, it might be wise to choose a no-lock-in contract plan to avoid these fees if you need flexibility.</p> <p>Electricity and gas connection and disconnection fees are usually minor but can add up, often costing about $40 to $60 for <a href="https://www.energyon.com.au/fees-and-charges/">connection and disconnection fees</a> for electricity alone. If your house uses gas for hot water or cooking, you may have to pay additional fees for setting up service.</p> <p>However, there are also <strong>non-financial costs</strong>, like the time spent searching for a new home, attending inspections, and putting in applications.</p> <p>Moving takes effort and energy for packing, transporting and unpacking.</p> <p>Some people feel emotionally attached to their current home, which can make leaving harder.</p> <p>Older renters <a href="https://www.sciencedirect.com/science/article/abs/pii/S1353829218311304">seem to draw strength</a> from their familiarity with, attachment to, and enjoyment of their place and community. This is something to be considered.</p> <p>Plus, moving can take <a href="https://www.nature.com/articles/s41537-023-00349-w">an emotional toll</a>.</p> <h2>The benefits of not moving</h2> <p>The clear benefit of staying is <strong>avoiding the hassle</strong> of relocating.</p> <p>Staying means saving on moving expenses and avoiding the time spent searching for a new place, packing and unpacking.</p> <p>This may also save some people from needing to take time off work.</p> <p>Changing and updating an address is also another tedious task that can be avoided by staying.</p> <p>Moving can hit the hip pocket with “<strong>after moving costs</strong>” that people may not initially consider.</p> <p>For instance, a new location might mean a longer commute. If each trip adds just 15 extra minutes, that could amount to an additional 11 hours per month over 22 workdays.</p> <p>For drivers, increased fuel and parking expenses might also come into play.</p> <p>Is the current or new location closer to a supermarket, hospital, and school? This proximity could be beneficial or detrimental, depending on the surrounding environment and available services.</p> <h2>To move or not to move?</h2> <p>One point to note is that overall, moving costs are likely to be similar between big cities and regional areas if you get moving supplies or rent a van from a large company such as Bunnings.</p> <p>In the end, moving costs will be around $2,000 based on the figures above, and it can be around $800 to $1,000 cheaper if you opt to rent a van instead of using a full-service moving company.</p> <p>Therefore, if the current rent is $600 per week and is about to increase by 10% to $660, the additional cost would be $3,120 per year.</p> <p>So is it cheaper to move or stay when your rent increases by 10%?</p> <p>The answer is moving may save about $1,000 to $2,000, but comes with the hassle and emotional toll of relocation. Staying will be more expensive, but with less hassle and emotional strain.</p> <p>The right choice depends on your situation.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/243155/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/park-thaichon-175182">Park Thaichon</a>, Associate Professor of Marketing, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> and <a href="https://theconversation.com/profiles/sara-quach-175976">Sara Quach</a>, Senior Lecturer in Marketing, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Does intermittent fasting increase or decrease our risk of cancer?

<p><em><a href="https://theconversation.com/profiles/amali-cooray-1482458">Amali Cooray</a>, <a href="https://theconversation.com/institutions/wehi-walter-and-eliza-hall-institute-of-medical-research-822"><em>WEHI (Walter and Eliza Hall Institute of Medical Research)</em></a></em></p> <p>Research over the years has suggested intermittent fasting has the potential to improve our health and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3946160/">reduce the likelihood</a> of developing cancer.</p> <p>So what should we make of a <a href="https://www.nature.com/articles/s41586-024-07840-z">new study</a> in mice suggesting fasting increases the risk of cancer?</p> <h2>What is intermittent fasting?</h2> <p>Intermittent fasting means switching between times of eating and not eating. Unlike traditional diets that focus on <em>what</em> to eat, this approach focuses on <em>when</em> to eat.</p> <p>There are lots of commonly used <a href="https://dietitiansaustralia.org.au/health-advice/intermittent-fasting">intermittent fasting schedules</a>. The 16/8 plan means you only eat within an eight-hour window, then fast for the remaining 16 hours. Another popular option is the 5:2 diet, where you eat normally for five days then restrict calories for two days.</p> <p>In Australia, poor diet contributes to <a href="https://www.health.gov.au/topics/food-and-nutrition/what-were-doing">7% of all cases of disease</a>, including coronary heart disease, stroke, type 2 diabetes, and cancers of the bowel and lung. Globally, poor diet is linked to <a href="https://www.thelancet.com/article/S0140-6736(19)30041-8/fulltext">22% of deaths</a> in adults over the age of 25.</p> <p>Intermittent fasting has gained a lot of attention in recent years for its potential health benefits. Fasting <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/metabolism">influences metabolism</a>, which is how your body processes food and energy. It can affect how the body absorbs nutrients from food and burns energy from sugar and fat.</p> <h2>What did the new study find?</h2> <p>The <a href="https://www.nature.com/articles/s41586-024-07840-z">new study</a>, published in Nature, found when mice ate again after fasting, their <a href="https://www.nature.com/articles/s12276-024-01179-1">gut stem cells</a>, which help repair the intestine, became more active. The stem cells were better at regenerating compared with those of mice who were either totally fasting or eating normally.</p> <p>This suggests the body might be better at healing itself when eating after fasting.</p> <p>However, this could also have a downside. If there are <a href="https://www.cancer.gov/about-cancer/causes-prevention/genetics/genetic-changes-infographic">genetic mutations</a> present, the burst of stem cell-driven regeneration after eating again might make it easier for cancer to develop.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4027058/">Polyamines</a> – small molecules important for cell growth – drive this regeneration after refeeding. These polyamines can be produced by the body, influenced by diet, or come from gut bacteria.</p> <p>The findings suggest that while fasting and refeeding can improve stem cell function and regeneration, there might be a tradeoff with an increased risk of cancer, especially if fasting and refeeding cycles are repeated over time.</p> <p>While this has been shown in mice, the link between intermittent fasting and cancer risk in humans is more complicated and not yet fully understood.</p> <h2>What has other research found?</h2> <p><a href="https://www.annualreviews.org/content/journals/10.1146/annurev-nutr-071816-064634">Studies in animals</a> have found intermittent fasting can help with weight loss, improve blood pressure and blood sugar levels, and subsequently <a href="https://pubmed.ncbi.nlm.nih.gov/27810402/">reduce the risks</a> of diabetes and heart disease.</p> <p>Research in humans <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2811116">suggests</a> intermittent fasting can reduce body weight, improve <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9361187/">metabolic health</a>, reduce inflammation, and enhance <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3946160/">cellular repair processes</a>, which remove damaged cells that could potentially turn cancerous.</p> <p>However, other studies warn that the benefits of intermittent fasting are the same as what can be achieved through <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2623528">calorie restriction</a>, and that there <a href="https://www.sciencedirect.com/science/article/pii/S2161831322007542">isn’t enough evidence</a> to confirm it reduces cancer risk in humans.</p> <h2>What about in people with cancer?</h2> <p>In studies of people who have cancer, fasting has been <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2815756/">reported to</a> protect against the side effects of chemotherapy and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7311547/">improve the effectiveness</a> of cancer treatments, while decreasing damage to healthy cells.</p> <p>Prolonged fasting in some patients who have cancer has been shown to be safe and <a href="https://pubmed.ncbi.nlm.nih.gov/34383300/">may potentially</a> be able to decrease tumour growth.</p> <p>On the other hand, some experts advise caution. Studies in mice show intermittent fasting could <a href="https://www.nature.com/articles/s41423-023-01033-w">weaken the immune system</a> and make the body less able to fight infection, potentially leading to worse health outcomes in people who are unwell. However, there is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8757987/">currently no evidence</a> that fasting increases the risk of bacterial infections in humans.</p> <h2>So is it OK to try intermittent fasting?</h2> <p>The current view on intermittent fasting is that it can be beneficial, but experts agree more research is needed. Short-term benefits such as weight loss and better overall health are well supported. But we don’t fully understand the long-term effects, especially when it comes to cancer risk and other immune-related issues.</p> <p>Since there are many different methods of intermittent fasting and people react to them differently, it’s hard to <a href="https://www.nature.com/articles/s41423-023-01033-w">give advice that works for everyone</a>. And because most people who participated in the studies were overweight, or had diabetes or other health problems, we don’t know how the results apply to the broader population.</p> <p>For healthy people, intermittent fasting is generally considered safe. But it’s <a href="https://dietitiansaustralia.org.au/health-advice/intermittent-fasting">not suitable for everyone</a>, particularly those with certain medical conditions, pregnant or breastfeeding women, and people with a history of eating disorders. So consult your health-care provider before starting any fasting program.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/238071/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/amali-cooray-1482458">Amali Cooray</a>, PhD Candidate in Genetic Engineering and Cancer, <a href="https://theconversation.com/institutions/wehi-walter-and-eliza-hall-institute-of-medical-research-822">WEHI (Walter and Eliza Hall Institute of Medical Research)</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Constipation increases your risk of a heart attack, new study finds – and not just on the toilet

<p><em><a href="https://theconversation.com/profiles/vincent-ho-141549">Vincent Ho</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></p> <p>If you Google the terms “constipation” and “heart attack” it’s not long before the name Elvis Presley crops up. Elvis had a longstanding history of chronic constipation and <a href="https://www.pbs.org/newshour/health/elvis-addiction-was-the-perfect-prescription-for-an-early-death">it’s believed</a> he was straining very hard to poo, which then led to a fatal heart attack.</p> <p>We don’t know what really happened to the so-called King of Rock “n” Roll back in 1977. There were likely several contributing factors to his death, and this theory is one of many.</p> <p>But after this famous case researchers took a strong interest in the link between constipation and the risk of a heart attack.</p> <p>This includes a recent <a href="https://journals.physiology.org/doi/abs/10.1152/ajpheart.00519.2024">study</a> led by Australian researchers involving data from thousands of people.</p> <h2>Are constipation and heart attacks linked?</h2> <p>Large <a href="https://www.nature.com/articles/s41598-023-38068-y">population</a> <a href="https://pubmed.ncbi.nlm.nih.gov/32873621/">studies</a> show constipation is linked to an increased risk of heart attacks.</p> <p>For example, an <a href="https://www.nature.com/articles/s41598-023-38068-y">Australian study</a> involved more than 540,000 people over 60 in hospital for a range of conditions. It found constipated patients had a higher risk of high blood pressure, heart attacks and strokes compared to non-constipated patients of the same age.</p> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/32873621/">Danish study</a> of more than 900,000 people from hospitals and hospital outpatient clinics also found that people who were constipated had an increased risk of heart attacks and strokes.</p> <p>It was unclear, however, if this relationship between constipation and an increased risk of heart attacks and strokes would hold true for healthy people outside hospital.</p> <p>These Australian and Danish studies also did not factor in the effects of drugs used to treat high blood pressure (hypertension), which can make you constipated.</p> <h2>How about this new study?</h2> <p>The recent <a href="https://journals.physiology.org/doi/abs/10.1152/ajpheart.00519.2024">international study</a> led by Monash University researchers found a connection between constipation and an increased risk of heart attacks, strokes and heart failure in a general population.</p> <p>The researchers analysed data from the <a href="https://www.ukbiobank.ac.uk">UK Biobank</a>, a database of health-related information from about half a million people in the United Kingdom.</p> <p>The researchers identified more than 23,000 cases of constipation and accounted for the effect of drugs to treat high blood pressure, which can lead to constipation.</p> <p>People with constipation (identified through medical records or via a questionnaire) were twice as likely to have a heart attack, stroke or heart failure as those without constipation.</p> <p>The researchers found a strong link between high blood pressure and constipation. Individuals with hypertension who were also constipated had a 34% increased risk of a major heart event compared to those with just hypertension.</p> <p>The study only looked at the data from people of European ancestry. However, there is good reason to believe the link between constipation and heart attacks applies to other populations.</p> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/26812003/">Japanese study</a> looked at more than 45,000 men and women in the general population. It found people passing a bowel motion once every two to three days had a higher risk of dying from heart disease compared with ones who passed at least one bowel motion a day.</p> <h2>How might constipation cause a heart attack?</h2> <p>Chronic constipation can lead to straining when passing a stool. This can result in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">laboured breathing</a> and can lead to a rise in blood pressure.</p> <p>In <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">one Japanese study</a> including ten elderly people, blood pressure was high just before passing a bowel motion and continued to rise during the bowel motion. This increase in blood pressure lasted for an hour afterwards, a pattern not seen in younger Japanese people.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">One theory</a> is that older people have stiffer blood vessels due to atherosclerosis (thickening or hardening of the arteries caused by a build-up of plaque) and other age-related changes. So their high blood pressure can persist for some time after straining. But the blood pressure of younger people returns quickly to normal as they have more elastic blood vessels.</p> <p>As blood pressure rises, the risk of heart disease increases. The risk of developing heart disease <a href="https://pubmed.ncbi.nlm.nih.gov/12493255/">doubles</a> when systolic blood pressure (the top number in your blood pressure reading) rises permanently by 20 mmHg (millimetres of mercury, a standard measure of blood pressure).</p> <p>The systolic blood pressure rise with straining in passing a stool has been <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">reported to be</a> as high as 70 mmHg. This rise is only temporary but with persistent straining in chronic constipation this could lead to an increased risk of heart attacks.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/22256893/">Some people</a> with chronic constipation may have an impaired function of their vagus nerve, which controls various bodily functions, including digestion, heart rate and breathing.</p> <p>This impaired function can result in abnormalities of heart rate and over-activation of the flight-fight response. This can, in turn, lead to elevated blood pressure.</p> <p>Another intriguing avenue of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6399019/">research</a> examines the imbalance in gut bacteria in people with <a href="https://pubmed.ncbi.nlm.nih.gov/3596341/">constipation</a>.</p> <p>This imbalance, known as dysbiosis, can result in microbes and other substances leaking through the gut barrier into the bloodstream and triggering an immune response. This, in turn, can lead to low-grade inflammation in the blood circulation and arteries becoming stiffer, increasing the risk of a heart attack.</p> <p>This latest study also explored genetic links between constipation and heart disease. The researchers found shared genetic factors that underlie both constipation and heart disease.</p> <h2>What can we do about this?</h2> <p>Constipation affects around <a href="https://pubmed.ncbi.nlm.nih.gov/36826591/">19% of the global population</a> aged 60 and older. So there is a substantial portion of the population at an increased risk of heart disease due to their bowel health.</p> <p>Managing chronic constipation through dietary changes (particularly increased dietary fibre), increased physical activity, ensuring adequate hydration and using medications, if necessary, are all important ways to help improve bowel function and reduce the risk of heart disease.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237209/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/vincent-ho-141549"><em>Vincent Ho</em></a><em>, Associate Professor and clinical academic gastroenterologist, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Does eating ham, bacon and beef really increase your risk of developing type 2 diabetes?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/duane-mellor-136502">Duane Mellor</a>, <a href="https://theconversation.com/institutions/aston-university-1107">Aston University</a></em></p> <p>That lunchtime staple, the humble ham sandwich, has come in for a bashing in the press recently. According to <a href="https://www.theguardian.com/society/article/2024/aug/20/two-slices-of-ham-a-day-can-raise-type-2-diabetes-risk-by-15-research-suggests">many</a> <a href="https://www.dailymail.co.uk/health/article-13761253/Eating-ham-daily-linked-increase-risk-diabetes.html">reports</a>, eating two slices of ham a day can increase your risk of developing type 2 diabetes.</p> <p>But what’s the science behind these headlines?</p> <p>The research offers a more complex picture. <a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(24)00179-7/fulltext">A new study</a> from the University of Cambridge highlighted an association between developing type 2 diabetes and eating processed meat like ham and bacon, and red meat such as beef and lamb.</p> <p>This led to headlines suggesting the risk was mainly linked to <a href="https://www.telegraph.co.uk/news/2024/08/21/ham-sandwich-processed-meat-fresh-risk-link-type-2-diabetes/">ham sandwiches</a>. This seems to have come from the <a href="https://www.cam.ac.uk/research/news/red-and-processed-meat-consumption-associated-with-higher-type-2-diabetes-risk">press release</a>, which used ham as the example to quantify the amount of processed meat associated with a 15% increased risk of developing type 2 diabetes over ten years.</p> <p>The research found that this risk was linked to eating an extra 50g of processed meat every day, which happens to equate to two slices of ham. A useful example thus appears to have been taken up by the media as the main cause, perhaps ignoring some of the key messages coming from the study.</p> <p>So, can processed and red meat really increase your risk of developing type 2 diabetes?</p> <p>The <a href="https://www.diabetes.org.uk/diabetes-the-basics/types-of-diabetes/type-2/diabetes-risk-factors">biggest risk factors</a> linked to developing type 2 diabetes are being over 40, having family members with type 2 diabetes, being of South Asian or African descent, or having a higher body weight – and especially a larger waist.</p> <figure><iframe src="https://www.youtube.com/embed/EsOBcx2bJqU?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>The Cambridge study used data from nearly 2 million people from 31 studies. Participants were followed for an average of ten years. During this time, around one in 20 people developed type 2 diabetes.</p> <p>The research suggested that a 10% increase in the probability of developing type 2 diabetes was associated with every 100g of additional red meat eaten daily. Eating half as much extra processed meat every day was linked to an even greater increased risk of developing the disease.</p> <p>This is not the <a href="https://ajcn.nutrition.org/article/S0002-9165(23)66119-2/abstract">first time</a> that both processed and red meats have been linked with an increased risk of developing type 2 diabetes. However, the key strength of the Cambridge study was that it tried to control for many of the other factors linked to the disease, including smoking, having a higher body weight, dietary intake and exercise.</p> <p>However, the size of the increased risk is modest, considering few people included in the study ate 50g or more processed meat per day – meaning moderate ham consumption is likely to have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9908545/">no meaningful effect</a> on your risk.</p> <h2>What’s the link?</h2> <p>Processed meat has been linked to increased risk of type 2 diabetes because of its nitrate and salt content – additives that are used to cure many processed meats.</p> <p>Nitrates and salt in processed meats have also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893523/">been linked to</a> an increased risk of developing colon cancer. In fact, the World Health Organization classifies the additives as <a href="https://www.who.int/news-room/questions-and-answers/item/cancer-carcinogenicity-of-the-consumption-of-red-meat-and-processed-meat">group 1 carcinogens</a>, which means they can cause a range of cancers.</p> <p>The mechanism linking processed meat to cancer seems to be similar to how it might be linked to type 2 diabetes. During digestion, processed meat produces <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6294997/">N-nitroso chemicals</a>, which can damage cells. This can lead to inflammation and affects how insulin, the hormone that controls blood glucose (sugar), works. This in turn can lead to <a href="https://www.niddk.nih.gov/health-information/diabetes/overview/what-is-diabetes/prediabetes-insulin-resistance">insulin resistance</a>, when cells in your muscles, fat and liver don’t respond well to insulin and can’t easily take up glucose from your blood.</p> <p>Red meat, meanwhile, is <a href="https://www.healthline.com/nutrition/healthy-iron-rich-foods">rich in iron</a>. Research suggests that people with <a href="https://www.diabetes.org.uk/diabetes-the-basics/related-conditions/haemochromatosis-diabetes#:%7E:text=So%20a%20rise%20of%20iron,GP%20as%20soon%20as%20possible.">high levels of iron</a> are more likely to develop type 2 diabetes. However, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8744124/#:%7E:text=The%20WHO%20has%20recognised%20iron,being%20affected%20with%20this%20condition.">low levels of iron</a> are more of a health concern for the general population.</p> <p>Another potential link regarding red meat could be the way it is cooked.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5521980/">Previous studies</a> have suggested that charred meat, cooked over an open flame or at high temperature, is also linked to an increased risk of developing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5911789/">type 2 diabetes</a>. Charring meat leads to formation of toxic chemicals such as <a href="https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/heterocyclic-amine#:%7E:text=Heterocyclic%20amines%20are%20aromatic%20compounds,of%20reactions%20called%20Maillard%20reactions.">heterocyclic aromatic amines</a> and harmful compounds like <a href="https://www.healthline.com/nutrition/advanced-glycation-end-products">advanced glycation end products</a>, both of which have been linked to <a href="https://pubmed.ncbi.nlm.nih.gov/21709297/">insulin resistance and type 2 diabetes</a>.</p> <h2>Bye-bye barbecues and bacon butties?</h2> <p>The key message is reduction, rather than avoidance. The UK government nutritional recommendations offer sound advice: limit your combined intake of red and processed meat to no more than <a href="https://www.nhs.uk/live-well/eat-well/food-types/meat-nutrition/#:%7E:text=Red%20meat%20and%20processed%20meat&amp;text=If%20you%20currently%20eat%20more,%2C%20veal%2C%20venison%20and%20goat.">an average of 70g per day</a>.</p> <p>But these guidelines also suggest that red meat can be a valuable source of iron. So, if you decide to stop eating red meat, you should eat alternative sources of iron such as beans, lentils, dark green vegetables and fortified cereals.</p> <p>This needs to be done as part of a carefully planned diet. Non-meat sources of iron are more difficult for our bodies to absorb so should be eaten with a source of vitamin C, found in green vegetables and citrus fruit.</p> <p>The best advice to reduce your risk of developing type 2 diabetes is to maintain a healthy weight – consider losing weight if you have a higher body weight – and be as physically active as possible.</p> <p>A healthy diet should be based on plenty of vegetables, fruit, beans, peas, lentils, nuts and seeds, along with some wholegrain foods, some dairy products, fish and white meat (or vegetarian alternatives) – plus moderate amounts of red meat and minimal processed meat. This will help reduce your risk of type 2 diabetes, <a href="https://www.bhf.org.uk/informationsupport/support/healthy-living/healthy-eating">heart disease</a>, and <a href="https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/diet-and-cancer/does-having-a-healthy-diet-reduce-my-risk-of-cancer">many cancers</a> – as well being more <a href="https://www.bda.uk.com/static/539e2268-7991-4d24-b9ee867c1b2808fc/a1283104-a0dd-476b-bda723452ae93870/one%20blue%20dot%20reference%20guide.pdf">environmentally sustainable</a>.</p> <p>But if you have a penchant for ham sandwiches, rest assured you can continue to indulge as an occasional treat.

How long does back pain last? And how can learning about pain increase the chance of recovery?

<p><em><a href="https://theconversation.com/profiles/sarah-wallwork-1361569">Sarah Wallwork</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/lorimer-moseley-1552">Lorimer Moseley</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Back pain is common. One in thirteen people have it right now and worldwide a staggering 619 million people will <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7186678/">have it this year</a>.</p> <p>Chronic pain, of which back pain is the most common, is the world’s <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7186678/">most disabling</a> health problem. Its economic impact <a href="https://www.ncbi.nlm.nih.gov/books/NBK92510/">dwarfs other health conditions</a>.</p> <p>If you get back pain, how long will it take to go away? We scoured the scientific literature to <a href="https://www.cmaj.ca/content/cmaj/196/2/E29.full.pdf">find out</a>. We found data on almost 20,000 people, from 95 different studies and split them into three groups:</p> <ul> <li>acute – those with back pain that started less than six weeks ago</li> <li>subacute – where it started between six and 12 weeks ago</li> <li>chronic – where it started between three months and one year ago.</li> </ul> <p>We found 70%–95% of people with acute back pain were likely to recover within six months. This dropped to 40%–70% for subacute back pain and to 12%–16% for chronic back pain.</p> <p>Clinical guidelines point to graded return to activity and pain education under the guidance of a health professional as the best ways to promote recovery. Yet these effective interventions are underfunded and hard to access.</p> <h2>More pain doesn’t mean a more serious injury</h2> <p>Most acute back pain episodes are <a href="https://www.racgp.org.au/getattachment/75af0cfd-6182-4328-ad23-04ad8618920f/attachment.aspx">not caused</a> by serious injury or disease.</p> <p>There are rare exceptions, which is why it’s wise to see your doctor or physio, who can check for signs and symptoms that warrant further investigation. But unless you have been in a significant accident or sustained a large blow, you are unlikely to have caused much damage to your spine.</p> <p>Even very minor back injuries can be brutally painful. This is, in part, because of how we are made. If you think of your spinal cord as a very precious asset (which it is), worthy of great protection (which it is), a bit like the crown jewels, then what would be the best way to keep it safe? Lots of protection and a highly sensitive alarm system.</p> <p>The spinal cord is protected by strong bones, thick ligaments, powerful muscles and a highly effective alarm system (your nervous system). This alarm system can trigger pain that is so unpleasant that you cannot possibly think of, let alone do, anything other than seek care or avoid movement.</p> <p>The messy truth is that when pain persists, the pain system becomes more sensitive, so a widening array of things contribute to pain. This pain system hypersensitivity is a result of neuroplasticity – your nervous system is becoming better at making pain.</p> <h2>Reduce your chance of lasting pain</h2> <p>Whether or not your pain resolves is not determined by the extent of injury to your back. We don’t know all the factors involved, but we do know there are things that you can do to reduce chronic back pain:</p> <ul> <li> <p>understand how pain really works. This will involve intentionally learning about modern pain science and care. It will be difficult but rewarding. It will help you work out what you can do to change your pain</p> </li> <li> <p>reduce your pain system sensitivity. With guidance, patience and persistence, you can learn how to gradually retrain your pain system back towards normal.</p> </li> </ul> <h2>How to reduce your pain sensitivity and learn about pain</h2> <p>Learning about “how pain works” provides the most sustainable <a href="https://www.bmj.com/content/376/bmj-2021-067718">improvements in chronic back pain</a>. Programs that combine pain education with graded brain and body exercises (gradual increases in movement) can reduce pain system sensitivity and help you return to the life you want.</p> <p>These programs have been in development for years, but high-quality clinical trials <a href="https://jamanetwork.com/journals/jama/fullarticle/2794765">are now emerging</a> and it’s good news: they show most people with chronic back pain improve and many completely recover.</p> <p>But most clinicians aren’t equipped to deliver these effective programs – <a href="https://www.jpain.org/article/S1526-5900(23)00618-1/fulltext">good pain education</a> is not taught in most medical and health training degrees. Many patients still receive ineffective and often risky and expensive treatments, or keep seeking temporary pain relief, hoping for a cure.</p> <p>When health professionals don’t have adequate pain education training, they can deliver bad pain education, which leaves patients feeling like they’ve just <a href="https://www.jpain.org/article/S1526-5900(23)00618-1/fulltext">been told it’s all in their head</a>.</p> <p>Community-driven not-for-profit organisations such as <a href="https://www.painrevolution.org/">Pain Revolution</a> are training health professionals to be good pain educators and raising awareness among the general public about the modern science of pain and the best treatments. Pain Revolution has partnered with dozens of health services and community agencies to train more than <a href="https://www.painrevolution.org/find-a-lpe">80 local pain educators</a> and supported them to bring greater understanding and improved care to their colleagues and community.</p> <p>But a broader system-wide approach, with government, industry and philanthropic support, is needed to expand these programs and fund good pain education. To solve the massive problem of chronic back pain, effective interventions need to be part of standard care, not as a last resort after years of increasing pain, suffering and disability.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/222513/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/sarah-wallwork-1361569">Sarah Wallwork</a>, Post-doctoral Researcher, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/lorimer-moseley-1552">Lorimer Moseley</a>, Professor of Clinical Neurosciences and Foundation Chair in Physiotherapy, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Readers response: What are your thoughts on the increasing use of digital payments?

<p>While technology continues to advance, so does the way we pay for things. </p> <p>Many shopping outlets have turned to using digital payment methods rather than cash, which has divided many who find it easier to use cold hard cash than rely on technology. </p> <p>We asked our readers their thoughts on digital payments and the response was overwhelming. Here's what they said. </p> <p><strong>Joan Hughes</strong> - Couldn’t go shopping due to bad pains in my leg and back, so my grandson did an online shop. Tried to use my card 5 times but wouldn’t accept it, so had to use my granddaughter's. This is the 3rd time my card has been rejected. Rubbish system, cash is definitely best.</p> <p><strong>Johanna Shakes</strong> - Very hard to adjust for elderly.</p> <p><strong>Debra Walker</strong> - Hate it! Cash is king.</p> <p><strong>Lex Jordan</strong> - I think we should all stand and boycott these companies that don't accept cash.</p> <p><strong>Patricia Tebbit</strong> - Don't mind using cards but access to cash is imperative. Think of small charity raffles, garage sales &amp; countless other things where cash is required.</p> <p><strong>Lyn Bradford</strong> - I love it, I use 95% card, 5% cash. So much easier. </p> <p><strong>David Taylor</strong> - Just making it easier for hackers.</p> <p><strong>Jennifer Bucktin</strong> - Cash is best. If digital goes down, you can't use anything.</p> <p><strong>Steve Smith</strong> - The digital age is here to stay so it's going to be better for all to get used to it.</p> <p><strong>Quentin Brown </strong>- Love them both, digital and cash as it's much easier to pay bills etc. Of course you have to be smart and not gullible. Why can't we have both?</p> <p><strong>Kath Sheppard</strong> - Cash is king, a lot safer as well, can't overspend either or be charged fees.</p> <p><em>Image credits: Shutterstock </em></p>

Menopause can bring increased cholesterol levels and other heart risks. Here’s why and what to do about it

<p><em><a href="https://theconversation.com/profiles/treasure-mcguire-135225">Treasure McGuire</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Menopause is a natural biological process that marks the end of a woman’s reproductive years, typically between 45 and 55. As women approach or experience menopause, common “change of life” <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9244939/">concerns</a> include hot flushes, sweats and mood swings, brain fog and fatigue.</p> <p>But many women may not be aware of the <a href="https://pubmed.ncbi.nlm.nih.gov/32705886/">long-term effects</a> of menopause on the heart and blood vessels that make up the cardiovascular system. Heart disease accounts for <a href="http://world-heart-federation.org/what-we-do/women-cvd/">35% of deaths</a> in women each year – more than all cancers combined.</p> <p>What should women – and their doctors – know about these risks?</p> <h2>Hormones protect hearts – until they don’t</h2> <p>As early as 1976, the <a href="https://pubmed.ncbi.nlm.nih.gov/970770/">Framingham Heart Study</a> reported more than twice the rates of cardiovascular events in postmenopausal than pre-menopausal women of the same age. Early menopause (younger than age 40) also <a href="https://pubmed.ncbi.nlm.nih.gov/25331207/">increases heart risk</a>.</p> <p>Before menopause, women tend to be protected by their circulating hormones: oestrogen, to a lesser extent progesterone and low levels of testosterone.</p> <p>These sex hormones help to relax and dilate blood vessels, reduce inflammation and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10503403/">improve lipid (cholesterol) levels</a>. From the mid-40s, a decline in these hormone levels can <a href="https://pubmed.ncbi.nlm.nih.gov/10362825/">contribute to unfavourable changes</a> in cholesterol levels, blood pressure and weight gain – all risk factors for heart disease.</p> <h2>4 ways hormone changes impact heart risk</h2> <p><strong>1. Dyslipidaemia</strong>– Menopause often involves <a href="https://pubmed.ncbi.nlm.nih.gov/38002671/">atherogenic changes</a> – an unhealthy imbalance of lipids in the blood, with higher levels of total cholesterol, triglycerides, and low-density lipoprotein (LDL-C), dubbed the “bad” cholesterol. There are also reduced levels of high-density lipoprotein (HDL-C) – the “good” cholesterol that helps remove LDL-C from blood. These changes are a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10503403/">major risk factor for heart attack or stroke</a>.</p> <p><strong>2. Hypertension</strong> – Declines in oestrogen and progesterone levels during menopause contribute to narrowing of the large blood vessels on the heart’s surface, arterial stiffness and <a href="https://pubmed.ncbi.nlm.nih.gov/35722103/">raise blood pressure</a>.</p> <p><strong>3. Weight gain</strong> – Females are born with one to two million eggs, which develop in follicles. By the time they <a href="https://www.thewomens.org.au/health-information/fertility-information/getting-pregnant/ovulation-and-conception">stop ovulating</a> in midlife, fewer than 1,000 remain. This depletion progressively changes fat distribution and storage, from the hips to the waist and abdomen. Increased waist circumference (greater than 80–88 cm) has been <a href="https://pubmed.ncbi.nlm.nih.gov/18359190/">reported to contribute to heart risk</a> – though it is <a href="https://theconversation.com/good-news-midlife-health-is-about-more-than-a-waist-measurement-heres-why-226019">not the only factor to consider</a>.</p> <p><strong>4. Comorbidities</strong> – Changes in body composition, sex hormone decline, increased food consumption, weight gain and sedentary lifestyles impair the body’s ability to effectively use insulin. This <a href="https://pubmed.ncbi.nlm.nih.gov/11133069/">increases the risk</a> of developing metabolic syndromes such as type 2 diabetes.</p> <p>While risk factors apply to both genders, hypertension, smoking, obesity and type 2 diabetes confer a greater relative risk for heart disease in women.</p> <h2>So, what can women do?</h2> <p>Every woman has a different level of baseline cardiovascular and metabolic risk pre-menopause. This is based on their genetics and family history, diet, and lifestyle. But all women can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8351755/">reduce their post-menopause heart risk with</a>:</p> <ul> <li>regular moderate intensity exercise such as brisk walking, pushing a lawn mower, riding a bike or water aerobics for 30 minutes, four or five times every week</li> <li>a healthy heart diet with smaller portion sizes (try using a smaller plate or bowl) and more low-calorie, nutrient-rich foods such as vegetables, fruit and whole grains</li> <li>plant sterols (unrefined vegetable oil spreads, nuts, seeds and grains) each day. A review of 14 clinical trials found plant sterols, at doses of at least 2 grams a day, produced an average reduction in serum LDL-C (bad cholesterol) of about 9–14%. This could reduce the risk of heart disease by <a href="https://pubmed.ncbi.nlm.nih.gov/10731187/">25% in two years</a></li> <li>less unhealthy (saturated or trans) fats and more low-fat protein sources (lean meat, poultry, fish – especially oily fish high in omega-3 fatty acids), legumes and low-fat dairy</li> <li>less high-calorie, high-sodium foods such as processed or fast foods</li> <li>a reduction or cessation of smoking (nicotine or cannabis) and alcohol</li> <li>weight-gain management or prevention.</li> </ul> <h2>What about hormone therapy medications?</h2> <p>Hormone therapy remains the most effective means of <a href="https://pubmed.ncbi.nlm.nih.gov/15495039/">managing hot flushes and night sweats</a> and is beneficial for <a href="https://pubmed.ncbi.nlm.nih.gov/18418063/">slowing the loss of bone mineral density</a>.</p> <p>The decision to recommend oestrogen alone or a combination of oestrogen plus progesterone hormone therapy depends on whether a woman has had a hysterectomy or not. The choice also depends on whether the hormone therapy benefit outweighs the woman’s disease risks. Where symptoms are bothersome, hormone therapy has <a href="https://pubmed.ncbi.nlm.nih.gov/33841322/">favourable or neutral effects on coronary heart disease risk</a> and medication risks are low for healthy women younger than 60 or within ten years of menopause.</p> <p>Depending on the level of stroke or heart risk and the response to lifestyle strategies, some women may also require medication management to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8351755/">control high blood pressure or elevated cholesterol levels</a>. Up until the early 2000s, women were underrepresented in most outcome trials with lipid-lowering medicines.</p> <p>The <a href="https://pubmed.ncbi.nlm.nih.gov/25579834/">Cholesterol Treatment Trialists’ Collaboration</a> analysed 27 clinical trials of statins (medications commonly prescribed to lower cholesterol) with a total of 174,000 participants, of whom 27% were women. Statins were about as effective in women and men who had similar risk of heart disease in preventing events such as stroke and heart attack.</p> <p>Every woman approaching menopause should ask their GP for a 20-minute <a href="https://www.health.gov.au/news/heart-health">Heart Health Check</a> to help better understand their risk of a heart attack or stroke and get tailored strategies to reduce it.</p> <p><em><a href="https://theconversation.com/profiles/treasure-mcguire-135225">Treasure McGuire</a>, Assistant Director of Pharmacy, Mater Health SEQ in conjoint appointment as Associate Professor of Pharmacology, Bond University and as Associate Professor (Clinical), <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Could not getting enough sleep increase your risk of type 2 diabetes?

<p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936"><em>University of Technology Sydney</em></a></em></p> <p>Not getting enough sleep is a common affliction in the modern age. If you don’t always get as many hours of shut-eye as you’d like, perhaps you were concerned by news of a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">recent study</a> that found people who sleep less than six hours a night are at higher risk of type 2 diabetes.</p> <p>So what can we make of these findings? It turns out the relationship between sleep and diabetes is complex.</p> <h2>The study</h2> <p>Researchers analysed data from the <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a>, a large biomedical database which serves as a global resource for health and medical research. They looked at information from 247,867 adults, following their health outcomes for more than a decade.</p> <p>The researchers wanted to understand the associations between sleep duration and type 2 diabetes, and whether a healthy diet reduced the effects of short sleep on diabetes risk.</p> <p>As part of their involvement in the UK Biobank, participants had been asked roughly how much sleep they get in 24 hours. Seven to eight hours was the average and considered normal sleep. Short sleep duration was broken up into three categories: mild (six hours), moderate (five hours) and extreme (three to four hours). The researchers analysed sleep data alongside information about people’s diets.</p> <p>Some 3.2% of participants were diagnosed with type 2 diabetes during the follow-up period. Although healthy eating habits were associated with a lower overall risk of diabetes, when people ate healthily but slept less than six hours a day, their risk of type 2 diabetes increased compared to people in the normal sleep category.</p> <p>The researchers found sleep duration of five hours was linked with a 16% higher risk of developing type 2 diabetes, while the risk for people who slept three to four hours was 41% higher, compared to people who slept seven to eight hours.</p> <p>One limitation is the study defined a healthy diet based on the number of servings of fruit, vegetables, red meat and fish a person consumed over a day or a week. In doing so, it didn’t consider how dietary patterns such as time-restricted eating or the Mediterranean diet may modify the risk of diabetes among those who slept less.</p> <p>Also, information on participants’ sleep quantity and diet was only captured at recruitment and may have changed over the course of the study. The authors acknowledge these limitations.</p> <h2>Why might short sleep increase diabetes risk?</h2> <p>In people with <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">type 2 diabetes</a>, the body becomes resistant to the effects of a hormone called insulin, and slowly loses the capacity to produce enough of it in the pancreas. Insulin is important because it regulates glucose (sugar) in our blood that comes from the food we eat by helping move it to cells throughout the body.</p> <p>We don’t know the precise reasons why people who sleep less may be at higher risk of type 2 diabetes. But <a href="https://doi.org/10.7759/cureus.23501">previous research</a> has shown sleep-deprived people often have increased <a href="https://doi.org/10.1186/1476-511X-9-125">inflammatory markers</a> and <a href="https://doi.org/10.1007/s00125-015-3500-4">free fatty acids</a> in their blood, which <a href="https://doi.org/10.1007/s11892-018-1055-8">impair insulin sensitivity</a>, leading to <a href="https://doi.org/10.7759/cureus.23501">insulin resistance</a>. This means the body struggles to use insulin properly to regulate blood glucose levels, and therefore increases the risk of type 2 diabetes.</p> <p>Further, people who don’t sleep enough, as well as people who sleep in irregular patterns (such as shift workers), experience disruptions to their body’s natural rhythm, known as the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5995632/">circadian rhythm</a>.</p> <p>This can interfere with the release of hormones like <a href="https://doi.org/10.1210/edrv.18.5.0317">cortisol, glucagon and growth hormones</a>. These hormones are released through the day to meet the body’s changing energy needs, and normally keep blood glucose levels nicely balanced. If they’re compromised, this may reduce the body’s ability to handle glucose as the day progresses.</p> <p>These factors, and <a href="https://www.science.org/doi/10.1126/sciadv.aar8590">others</a>, may contribute to the increased risk of type 2 diabetes seen among people sleeping less than six hours.</p> <p>While this study primarily focused on people who sleep eight hours or less, it’s possible longer sleepers may also face an increased risk of type 2 diabetes.</p> <p>Research has previously shown a U-shaped correlation between sleep duration and type 2 diabetes risk. A <a href="https://doi.org/10.2337/dc14-2073">review</a> of multiple studies found getting between seven to eight hours of sleep daily was associated with the lowest risk. When people got less than seven hours sleep, or more than eight hours, the risk began to increase.</p> <p>The reason sleeping longer is associated with increased risk of type 2 diabetes may be linked to <a href="https://doi.org/10.2337/dc15-0186">weight gain</a>, which is also correlated with longer sleep. Likewise, people who don’t sleep enough are more likely to be <a href="https://doi.org/10.1016/j.sleh.2017.07.013">overweight or obese</a>.</p> <h2>Good sleep, healthy diet</h2> <p>Getting enough sleep is an important part of a healthy lifestyle and may reduce the risk of type 2 diabetes.</p> <p>Based on this study and other evidence, it seems that when it comes to diabetes risk, seven to eight hours of sleep may be the sweet spot. However, other factors could influence the relationship between sleep duration and diabetes risk, such as individual differences in sleep quality and lifestyle.</p> <p>While this study’s findings question whether a healthy diet can mitigate the effects of a lack of sleep on diabetes risk, a wide range of evidence points to the benefits of <a href="https://www.who.int/initiatives/behealthy/healthy-diet">healthy eating</a> for overall health.</p> <p>The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">authors of the study</a> acknowledge it’s not always possible to get enough sleep, and suggest doing <a href="https://pubmed.ncbi.nlm.nih.gov/33137489/">high-intensity interval exercise</a> during the day may offset some of the potential effects of short sleep on diabetes risk.</p> <p>In fact, exercise <a href="https://doi.org/10.1016/j.jshs.2023.03.001">at any intensity</a> can improve blood glucose levels.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225179/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, Casual Academic, Faculty of Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, Senior Lecturer, School of Public Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How long does back pain last? And how can learning about pain increase the chance of recovery?

<p><em><a href="https://theconversation.com/profiles/sarah-wallwork-1361569">Sarah Wallwork</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/lorimer-moseley-1552">Lorimer Moseley</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Back pain is common. One in thirteen people have it right now and worldwide a staggering 619 million people will <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7186678/">have it this year</a>.</p> <p>Chronic pain, of which back pain is the most common, is the world’s <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7186678/">most disabling</a> health problem. Its economic impact <a href="https://www.ncbi.nlm.nih.gov/books/NBK92510/">dwarfs other health conditions</a>.</p> <p>If you get back pain, how long will it take to go away? We scoured the scientific literature to <a href="https://www.cmaj.ca/content/cmaj/196/2/E29.full.pdf">find out</a>. We found data on almost 20,000 people, from 95 different studies and split them into three groups:</p> <ul> <li>acute – those with back pain that started less than six weeks ago</li> <li>subacute – where it started between six and 12 weeks ago</li> <li>chronic – where it started between three months and one year ago.</li> </ul> <p>We found 70%–95% of people with acute back pain were likely to recover within six months. This dropped to 40%–70% for subacute back pain and to 12%–16% for chronic back pain.</p> <p>Clinical guidelines point to graded return to activity and pain education under the guidance of a health professional as the best ways to promote recovery. Yet these effective interventions are underfunded and hard to access.</p> <h2>More pain doesn’t mean a more serious injury</h2> <p>Most acute back pain episodes are <a href="https://www.racgp.org.au/getattachment/75af0cfd-6182-4328-ad23-04ad8618920f/attachment.aspx">not caused</a> by serious injury or disease.</p> <p>There are rare exceptions, which is why it’s wise to see your doctor or physio, who can check for signs and symptoms that warrant further investigation. But unless you have been in a significant accident or sustained a large blow, you are unlikely to have caused much damage to your spine.</p> <p>Even very minor back injuries can be brutally painful. This is, in part, because of how we are made. If you think of your spinal cord as a very precious asset (which it is), worthy of great protection (which it is), a bit like the crown jewels, then what would be the best way to keep it safe? Lots of protection and a highly sensitive alarm system.</p> <p>The spinal cord is protected by strong bones, thick ligaments, powerful muscles and a highly effective alarm system (your nervous system). This alarm system can trigger pain that is so unpleasant that you cannot possibly think of, let alone do, anything other than seek care or avoid movement.</p> <p>The messy truth is that when pain persists, the pain system becomes more sensitive, so a widening array of things contribute to pain. This pain system hypersensitivity is a result of neuroplasticity – your nervous system is becoming better at making pain.</p> <h2>Reduce your chance of lasting pain</h2> <p>Whether or not your pain resolves is not determined by the extent of injury to your back. We don’t know all the factors involved, but we do know there are things that you can do to reduce chronic back pain:</p> <ul> <li> <p>understand how pain really works. This will involve intentionally learning about modern pain science and care. It will be difficult but rewarding. It will help you work out what you can do to change your pain</p> </li> <li> <p>reduce your pain system sensitivity. With guidance, patience and persistence, you can learn how to gradually retrain your pain system back towards normal.</p> </li> </ul> <h2>How to reduce your pain sensitivity and learn about pain</h2> <p>Learning about “how pain works” provides the most sustainable <a href="https://www.bmj.com/content/376/bmj-2021-067718">improvements in chronic back pain</a>. Programs that combine pain education with graded brain and body exercises (gradual increases in movement) can reduce pain system sensitivity and help you return to the life you want.</p> <p>These programs have been in development for years, but high-quality clinical trials <a href="https://jamanetwork.com/journals/jama/fullarticle/2794765">are now emerging</a> and it’s good news: they show most people with chronic back pain improve and many completely recover.</p> <p>But most clinicians aren’t equipped to deliver these effective programs – <a href="https://www.jpain.org/article/S1526-5900(23)00618-1/fulltext">good pain education</a> is not taught in most medical and health training degrees. Many patients still receive ineffective and often risky and expensive treatments, or keep seeking temporary pain relief, hoping for a cure.</p> <p>When health professionals don’t have adequate pain education training, they can deliver bad pain education, which leaves patients feeling like they’ve just <a href="https://www.jpain.org/article/S1526-5900(23)00618-1/fulltext">been told it’s all in their head</a>.</p> <p>Community-driven not-for-profit organisations such as <a href="https://www.painrevolution.org/">Pain Revolution</a> are training health professionals to be good pain educators and raising awareness among the general public about the modern science of pain and the best treatments. Pain Revolution has partnered with dozens of health services and community agencies to train more than <a href="https://www.painrevolution.org/find-a-lpe">80 local pain educators</a> and supported them to bring greater understanding and improved care to their colleagues and community.</p> <p>But a broader system-wide approach, with government, industry and philanthropic support, is needed to expand these programs and fund good pain education. To solve the massive problem of chronic back pain, effective interventions need to be part of standard care, not as a last resort after years of increasing pain, suffering and disability.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/222513/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/sarah-wallwork-1361569">Sarah Wallwork</a>, Post-doctoral Researcher, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/lorimer-moseley-1552">Lorimer Moseley</a>, Professor of Clinical Neurosciences and Foundation Chair in Physiotherapy, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do stress and depression increase the risk of Alzheimer’s disease? Here’s why there might be a link

<p><em><a href="https://theconversation.com/profiles/yen-ying-lim-355185">Yen Ying Lim</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/ivana-chan-1477100">Ivana Chan</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Dementia affects more than <a href="https://www.who.int/news-room/fact-sheets/detail/dementia">55 million people</a> around the world. A number of factors can increase a person’s risk of developing dementia, <a href="https://link.springer.com/article/10.14283/jpad.2023.119">including</a> high blood pressure, poor sleep, and physical inactivity. Meanwhile, keeping cognitively, physically, and socially active, and limiting alcohol consumption, can <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">reduce the risk</a>.</p> <p>Recently, a <a href="https://alzres.biomedcentral.com/articles/10.1186/s13195-023-01308-4">large Swedish study</a> observed that chronic stress and depression were linked to a higher risk of developing <a href="https://alz-journals.onlinelibrary.wiley.com/doi/10.1002/alz.12638">Alzheimer’s disease</a>, the most common form of dementia. The researchers found people with a history of both chronic stress and depression had an even greater risk of the disease.</p> <p>Globally, around <a href="https://www.who.int/news-room/fact-sheets/detail/depression">280 million people</a> have depression, while roughly <a href="https://www.who.int/news-room/fact-sheets/detail/anxiety-disorders">300 million people</a> experience anxiety. With so many people facing mental health challenges at some stage in their lives, what can we make of this apparent link?</p> <h2>What the study did and found</h2> <p>This study examined the health-care records of more than 1.3 million people in Sweden aged between 18 and 65. Researchers looked at people diagnosed with chronic stress (technically chronic stress-induced exhaustion disorder), depression, or both, between 2012 and 2013. They compared them with people not diagnosed with chronic stress or depression in the same period.</p> <p>Participants were then followed between 2014 and 2022 to determine whether they received a diagnosis of mild cognitive impairment or dementia, in particular Alzheimer’s disease. <a href="https://alz-journals.onlinelibrary.wiley.com/doi/10.1016/j.jalz.2016.07.151">Mild cognitive impairment</a> is often seen as the precursor to dementia, although not everyone who has mild cognitive impairment will progress to dementia.</p> <p>During the study period, people with a history of either chronic stress or depression were around twice as likely to be diagnosed with mild cognitive impairment or Alzheimer’s disease. Notably, people with both chronic stress and depression were up to four times more likely to be diagnosed with mild cognitive impairment or Alzheimer’s disease.</p> <h2>Important considerations</h2> <p>In interpreting the results of this study, there are some key things to consider. First, the diagnosis of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9438479/">chronic stress-induced exhaustion disorder</a> is unique to the Swedish medical system. It is characterised by at least six months of intensive stress without adequate recovery. Symptoms include exhaustion, sleep disturbance and concentration difficulties, with a considerable reduction in ability to function. Mild stress may not have the same effect on dementia risk.</p> <p>Second, the number of people diagnosed with dementia in this study (the absolute risk) was very low. Of the 1.3 million people studied, 4,346 were diagnosed with chronic stress, 40,101 with depression, and 1,898 with both. Of these, the number who went on to develop Alzheimer’s disease was 14 (0.32%), 148 (0.37%) and 9 (0.47%) respectively.</p> <p>These small numbers may be due to a relatively young age profile. When the study began in 2012–2013, the average age of participants was around 40. This means the average age in 2022 was around 50. Dementia is typically diagnosed in <a href="https://www.health.gov.au/topics/dementia/about-dementia">people aged over 65</a> and diagnosis <a href="https://karger.com/dem/article-abstract/34/5-6/292/99009/Overdiagnosis-of-Dementia-in-Young-Patients-A?redirectedFrom=fulltext">in younger ages</a> may be less reliable.</p> <p>Finally, it’s possible that in some cases stress and depressive symptoms may reflect an awareness of an already declining memory ability, rather than these symptoms constituting a risk factor in themselves.</p> <p>This last consideration speaks to a broader point: the study is observational. This means it can’t tell us one thing caused the other – only that there is an association.</p> <h2>What does other evidence say?</h2> <p><a href="https://link.springer.com/article/10.14283/jpad.2023.119">Many studies</a> indicate that significant symptoms of depression, anxiety and stress are related to higher dementia risk. However, the nature of this relationship is unclear. For example, are depressive and anxiety symptoms a risk factor for dementia, or are they consequences of a declining cognition? It’s likely to be a bit of both.</p> <p>High <a href="https://pubmed.ncbi.nlm.nih.gov/32082139/">depressive and anxiety symptoms</a> are commonly reported in people with mild cognitive impairment. However, studies in middle-aged or younger adults suggest they’re important dementia risk factors too.</p> <p>For example, similar to the Swedish study, other <a href="https://www.sciencedirect.com/science/article/pii/S0165032719323031">studies</a> have suggested people with a history of depression are twice as likely to develop dementia than those without this history. In addition, in middle-aged adults, high anxiety symptoms are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34648818/">poorer cognitive function</a> and <a href="https://bmjopen.bmj.com/content/8/4/e019399">greater dementia risk</a> in later life.</p> <h2>Why the link?</h2> <p>There are several potential pathways through which stress, anxiety and depression could increase the risk of dementia.</p> <p>Animal studies suggest cortisol (a hormone produced when we’re stressed) can increase risk of Alzheimer’s disease by causing the accumulation of key proteins, <a href="https://pubmed.ncbi.nlm.nih.gov/34159699/">amyloid and tau</a>, in the brain. The accumulation of these proteins can result in increased <a href="https://www.mdpi.com/1422-0067/23/18/10572">brain inflammation</a>, which affects the brain’s nerves and supporting cells, and can ultimately lead to brain volume loss and memory decline.</p> <p>Another potential pathway is through <a href="https://www.sciencedirect.com/science/article/pii/S1087079217300114?via%3Dihub">impaired sleep</a>. Sleep disturbances are common in people with chronic stress and depression. Similarly, people with Alzheimer’s disease commonly report sleep disturbances. Even in people with <a href="https://pubmed.ncbi.nlm.nih.gov/34668959/">early Alzheimer’s disease</a>, disturbed sleep is related to poorer memory performance. Animal studies suggest poor sleep can also enhance accumulation of <a href="https://pubmed.ncbi.nlm.nih.gov/31408876/">amyloid and tau</a>.</p> <p>We still have a lot to learn about why this link might exist. But evidence-based strategies which target chronic stress, anxiety and depression may also play a role in reducing the risk of dementia.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/215065/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/yen-ying-lim-355185"><em>Yen Ying Lim</em></a><em>, Associate Professor, Turner Institute for Brain and Mental Health, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/ivana-chan-1477100">Ivana Chan</a>, PhD candidate, clinical psychology, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Don’t believe the hype. Menopausal women don’t all need to check – or increase – their testosterone levels

<p><em><a href="https://theconversation.com/profiles/susan-davis-10376">Susan Davis</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Ever heard “low testosterone” blamed for low mood, brain fog and loss of vitality? Despite all evidence to the contrary, social media influencers are increasingly promoting testosterone therapy as an elixir for women experiencing troubling symptoms of menopause.</p> <p>In a series of documentaries and <a href="https://www.dailymail.co.uk/health/article-11792553/Davina-McCall-effect-sparks-menopause-testosterone-treatment-rush-putting-women-risk.html">social media posts</a> about menopause in 2021 and 2022, British TV presenter Davina McCall promoted the use of testosterone therapy in addition to standard <a href="https://www.menopause.org.au/hp/information-sheets/combined-menopausal-hormone-therapy-mht">menopausal hormone therapy</a>. The “<a href="https://www.telegraph.co.uk/news/2023/02/17/davina-effect-fuels-surge-menopausal-women-using-testosterone/#:%7E:text=Chelsea%20Magazine%20Company-,'Davina%20effect'%20fuels%20surge%20in%20menopausal%20women%20using%20testosterone,NHS%20prescriptions%20for%20the%20hormone">Davina effect</a>” has helped fuel a <a href="https://pharmaceutical-journal.com/article/news/nhs-testosterone-prescribing-in-women-rises-ten-fold-in-seven-years#:%7E:text=The%20number%20of%20women%20in,The%20Pharmaceutical%20Journal%20has%20revealed">ten-fold increase</a> in prescribing of testosterone for women in the United Kingdom since 2015.</p> <p>Data isn’t available for Australia, but in my clinical practice, women are increasingly asking to have their testosterone level checked, and seeking testosterone to treat fatigue and brain fog.</p> <p>But while testosterone continues to be an important hormone before and after menopause, this doesn’t mean women should be having a blood test to get their testosterone levels checked – or taking testosterone therapy.</p> <h2>What does testosterone do?</h2> <p>Testosterone is an important hormone in women’s bodies, affecting the blood vessels, skin, muscle and bone, breast tissue and the brain. In both women and men, testosterone can act on its own or be converted into estrogen.</p> <p>Before menopause, testosterone is made in the ovaries, where it helps developing eggs grow and aids in estrogen production.</p> <p>The ovaries release both testosterone and estrogen into the bloodstream, and the levels of the two hormones in the blood peak around ovulation.</p> <p>Some of the testosterone measured in blood is also produced outside the ovaries, such as in fat, where it is made from “pre-hormones” secreted by the adrenal glands. This source of production of testosterone takes over after menopause.</p> <h2>Do we have more testosterone before menopause?</h2> <p>The claim is often made that pre-menopausal women have more testosterone in their bloodstream than estrogen, to justify the need for testosterone replacement after menopause.</p> <p>But, when sex hormones have been measured with precision, studies have shown this is not true. <a href="https://pubmed.ncbi.nlm.nih.gov/31390028/">Our research</a> found estrogen levels are higher than testosterone levels at all stages of the menstrual cycle.</p> <p>Blood testosterone levels <a href="https://pubmed.ncbi.nlm.nih.gov/31390028/">fall</a> by about 25% between the ages of 18 and 40 years in healthy women. The fall in testosterone coincides with the decline in eggs in the ovaries but whether this is a marker of the decline, a consequence, or a cause of the decline is not known.</p> <p>From around 40, the rate of decline slows and blood testosterone levels don’t change when <a href="https://www.menopause.org.au/hp/information-sheets/what-is-menopause">menopause</a> occurs naturally. Studies have not shown testosterone levels change meaningfully during the menopause transition.</p> <h2>Can blood tests detect ‘low testosterone’?</h2> <p>Some influencers claim to have a condition called “testosterone deficiency syndrome” or low levels of testosterone detected in blood tests.</p> <p>But there is no “normal” blood level below which a woman can be diagnosed as having “testosterone deficiency”. So there’s no such thing as having a testosterone deficiency or testosterone deficiency syndrome.</p> <p>This is also in part, because women have very low testosterone concentrations compared with men, and most commercial methods used to measure testosterone cannot separate normal from low levels in women with any certainty.</p> <p>Pre-menopausal women might also be told they have “low” testosterone if blood is drawn early in the menstrual cycle when it is normal for testosterone to be low. (However, it would only be clinically necessary to do this type of blood test to look for <em>high</em> testosterone, in someone with with excessive hair growth or severe acne, for example, not for <em>low</em> testosterone.)</p> <p>In post-menopausal women, much of the action of testosterone occurs in the tissues where it is made, after which testosterone is either converted to estrogen or broken down before it leaks back into the circulation. So blood testosterone concentrations are not a true reflection of tissue concentrations.</p> <p>Further complicating the picture is the enormous variability in the effects of testosterone. At a given blood level of testosterone, some women might have oily skin, acne, increased body hair growth or balding, while others will have no such effects.</p> <p>So, looking for a “low” blood testosterone in women is not helpful.</p> <h2>Can testosterone improve sexual desire? What about other conditions?</h2> <p>There is sound evidence that testosterone therapy may improve sexual desire in post-menopausal women who have developed low sexual desire that bothers them.</p> <p>This was <a href="https://www.tandfonline.com/doi/full/10.1080/13697137.2019.1637079">confirmed by</a> a <a href="https://pubmed.ncbi.nlm.nih.gov/31353194/">systematic review</a> of clinical trials comparing testosterone with a placebo or an alternative. These trials, all of which involved a treatment time of at least 12 weeks, showed testosterone therapy, overall, improved desire, arousal, orgasm and sexual satisfaction in post-menopausal women with low desire that caused them distress.</p> <p>Treatment is only indicated for women who want an improvement in sexual desire (after excluding other factors such as depression or medication side effects) and its success can only be determined by each woman’s personal self-reported response.</p> <p>But there is <a href="https://www.tandfonline.com/doi/full/10.1080/13697137.2019.1637079">not enough evidence</a> to show testosterone is beneficial for any other symptom or medical condition. The overall available data has shown no effect of testosterone on mood or cognition.</p> <p>As such, testosterone therapy <a href="https://www.tandfonline.com/doi/full/10.1080/13697137.2019.1637079">should not be used</a> to treat symptoms such as fatigue, low mood, muscle weakness and poor memory, or to prevent bone loss, dementia or breast cancer.</p> <p>However research continues to investigate these potential uses, including from my <a href="https://www.monash.edu/medicine/sphpm/units/womenshealth">research team</a>, which is investigating whether testosterone therapy can <a href="https://asbmr.onlinelibrary.wiley.com/doi/10.1002/jbmr.534">protect against bone density loss and muscle loss after menopause</a>.</p> <p><em>You can learn more about participating in one of our studies <a href="https://www.monash.edu/medicine/sphpm/units/womenshealth/join-a-study">here</a>.</em> <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/209516/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/susan-davis-10376">Susan Davis</a>, Chair of Women's Health, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to increase the value of your home in one weekend

<p>Increasing the value of your property pre-sale doesn’t have to require a team of professionals.</p> <p>Just one weekend dedicated to cleaning, refreshing, tidying and upgrading can put you in great stead for sales success.</p> <p>We asked the experts to reveal the best value-adding DIY projects to suit a short time frame and shoestring budget.</p> <p><strong>1. Refresh an old paint job</strong></p> <p>There is no easier way to boost a property’s value than a new paint job, which can range from a one-room refresh, to an extensive repaint of the entire home.</p> <p>For homeowners low on budget and time, focus on painting the main living areas with Dulux’s Wash&amp;Wear to disguise mismatched old paint, cracks and imperfections.</p> <p>“It’s great for interiors, especially in the matt finish. Even if the colours don’t entirely match, you can get away with it,” says Andrea Lucena-Orr, colour planning and communications manager at Dulux Australia.</p> <p>In terms of colour, white remains popular for appealing to a broad base of buyers.</p> <p>If painting an older property, opt for warmer whites such as Dulux Natural White or Antique White U.S.A ® Contemporary homes are more suited to cooler whites, with a grey or beige base, such as Dulux Lexicon ® or White on White.</p> <p><strong>2. Create a feature wall</strong></p> <p>Painting a feature wall can be a valuable method for creating a point of difference on a minimal timeframe. This might be a dark single shade in the main bedroom or a bold dual-colour wall.</p> <p>“Feature walls, nooks and colour-blocking with tape are all ways to add interest,” says Lucena-Orr.</p> <p>When selecting colours for a feature wall, look for shades that will complement the room’s existing furniture and décor items.</p> <p>“Try using colours to highlight an artwork, a piece of furniture, or tie into the bed linen,” Lucena-Orr says.</p> <p><strong>3. Tidy the exterior</strong></p> <p>If there is one area of the home you should focus on before a sale, it’s the exterior.</p> <p>While some homes will benefit from an entire façade repaint, updating this area can be achieved in a few quick jobs.</p> <p>Start by removing any cobwebs, cleaning the walls and filling in visible cracks. For added aesthetic appeal, paint some pots and place them near the front door, or spray paint a bench seat for the front porch.</p> <p>Painting the front door a colour such as cobalt or teal blue is another powerful tool for creating colour memories and attracting interest.</p> <p>“A teal door will help buyers remember the house. Even if buyers don’t like it, it’s quick and easy for them to change,” Lucena-Orr says.</p> <p><strong>4. Install storage shelves</strong></p> <p>Installing open shelves in the kitchen, bathroom, laundry and study is a simple way to integrate more storage into a property, which never goes unappreciated.</p> <p>“Installing hooks, rails or racks to your doors will spruce things up without being too dramatic or involve any structural changes,” says Bunnings category manager – decorator, Sharyn Petrzela.</p> <p>“Pull-out baskets and base-mount slide-out baskets are also a great way to add storage and can be installed in a day.”</p> <p><strong>5. Outsource odd jobs</strong></p> <p>Selling a home is stressful and time consuming. If budget allows, don’t be afraid to outsource tasks where you can.</p> <p>Websites such as Airtasker make it affordable to hire individuals for even the smallest household jobs, from removing weeds, to assembling furniture, collecting hard rubbish and hanging pictures.</p> <p>You might just want someone to focus on cleaning those detailed areas of the home such as the skirting boards, architraves, light fittings and door handles.</p> <p><strong>6. Add the finishing touches</strong></p> <p>If you can’t afford a professional property stylist to decorate your home pre-sale, try these expert tips.</p> <p>“As a stylist, I think having decorative items (vases, candle holders and similar) that have a colour theme and style that is carried through the house gives a sense of flow that makes a house feel like a whole, instead of a series of different rooms,” says Sophie Kost, director and lead designer of My Beautiful Abode.</p> <p>Even small updates like replacing the feather inserts in your couch cushions can have a big impact on the feeling of a home.</p> <p>Remember to declutter surfaces and remove personal possessions in this process, as this allows buyers to better imagine themselves in the space.</p> <p><em>Image credits: Getty Images</em></p>

Crypto scams will increase over the holidays – here’s what you need to know to not fall victim

<p>Each year, as the festive season arrives, we must also keep an eye out for potential scammers trying to ruin the fun. This is because scammers become more active <a href="https://www.scamwatch.gov.au/scam-statistics?scamid=all&amp;date=2021" target="_blank" rel="noopener">during the holidays</a>, targeting us while we have our guard down.</p> <p>So far in 2022, Australians have lost around <a href="https://www.scamwatch.gov.au/scam-statistics?scamid=all&amp;date=2022" target="_blank" rel="noopener">half a billion dollars to scams</a>, which is already significantly more than had been lost by this time last year.

They get the victim to transfer over funds and escape with them.</p> <p><strong>“Pump and dump”:</strong> scammers usually hype up a new cryptocurrency or an <a href="https://www.kaspersky.com/resource-center/preemptive-safety/how-to-avoid-nft-scams" target="_blank" rel="noopener">NFT project</a> and artificially increase its value. Once enough victims invest, the scammers sell their stake, leaving the victims with worthless cryptocurrency or NFT.</p> <p><strong>Romance scams:</strong> involves scammers using dating platforms, social media or direct messaging to engage with you, gain your trust and pitch an amazing investment opportunity promising high returns, or ask for cryptocurrency to cover medical or travel expenses.</p> <p><strong>Phishing scams:</strong> an old but still effective scam involving malicious emails or messages with links to fake websites promising huge returns on investment or just outright stealing credentials to access users’ digital currency wallets.</p> <p><strong>Ponzi schemes:</strong> a type of investment scam where the scammers use cryptocurrency gathered from multiple victims to repay high interest to some of them; when victims invest more funds, the scammers escape with all the investments.</p> <p><strong>Mining scams:</strong> scammers try and convince victims to buy cryptocurrency to use in mining more of it, while in reality there is no mining happening – the scammers just make transfers that look like returns on the investment. Over time, the victim invests more, and the scammers keep taking it all.</p> <p>Although methods evolve and change, the telltale signs of a potential scam remain relatively similar:</p> <ul> <li>very high returns with promises of little or no risk</li> <li>proprietary or secretive strategies to gain an advantage</li> <li>lack of liquidity, requiring a minimum accumulation amount before funds are released.</li> </ul> <p><strong>Where to seek help if you’ve been scammed</strong></p> <blockquote> <p>I felt helpless, I didn’t know what to do, who to reach out to, I was too embarrassed and just kept blaming myself. – (72-year-old male, accountant from Victoria)</p> </blockquote> <p>If you think you have fallen victim to one of these scams, here is what you need to do next:</p> <ul> <li> <p>inform the Australian Competition and Consumer Commission (ACCC) <a href="https://www.scamwatch.gov.au/report-a-scam" target="_blank" rel="noopener">here</a> or reach out to relevant authorities <a href="https://www.scamwatch.gov.au/get-help/where-to-get-help" target="_blank" rel="noopener">as per advice on the ScamWatch website</a></p> </li> <li> <p>reach out to your friends and family members and inform them of the scam; they can also be a source of help and support during such times</p> </li> <li> <p>as these events can have a psychological impact, it’s recommended you talk to your GP, a health professional, or someone you trust</p> </li> <li> <p>you can also reach out to counselling services such as <a href="http://www.lifeline.org.au/" target="_blank" rel="noopener">LifeLine</a>, <a href="https://www.beyondblue.org.au/" target="_blank" rel="noopener">beyond blue</a>, <a href="http://www.suicidecallbackservice.org.au/" target="_blank" rel="noopener">Sucide Call Back Service</a>, <a href="http://www.mensline.org.au/" target="_blank" rel="noopener">Mens Line</a>, and <a href="https://www.scamwatch.gov.au/get-help/where-to-get-help" target="_blank" rel="noopener">more</a> for help and support.</p> </li> </ul> <p>If you ever find yourself in a difficult situation, please remember help and support is available.</p> <p>Finally, to prevent yourself becoming the next statistic over the holiday period, keep in mind the following advice:<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/194064/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <ul> <li>don’t share your personal details with people online or over a call</li> <li>don’t invest in something you don’t understand</li> <li>if in doubt, talk to an expert or search online for resources yourself (don’t believe any links the scammers send you).</li> </ul> <p><em>Writen by Ashish Nanda, Jeb Webb, Jongkil Jay Jeong, Mohammed Reza Nosouhi, and Syed Wajid Ali Shah.

Does picking your nose really increase your risk of dementia?

<p>No matter your age, we all pick our nose.</p> <p>However, if gripping headlines around the world are a sign, this habit could increase your risk of Alzheimer’s disease, the most common form of dementia.</p> <p>One international news report <a href="https://www.the-sun.com/health/6565520/common-habit-increase-risk-alzheimers-dementia/">said</a>:</p> <blockquote> <p>‘SCARY EVIDENCE’ How a common habit could increase your risk of Alzheimer’s and dementia</p> </blockquote> <p>Another <a href="https://www.mirror.co.uk/news/health/alzheimers-disease-risk-increased-picking-28378042">ran with</a>:</p> <blockquote> <p>Alzheimer’s disease risk increased by picking your nose and plucking hair, warns study</p> </blockquote> <p>An Australian news article <a href="https://www.sbs.com.au/news/article/could-picking-your-nose-lead-to-dementia-australian-researchers-are-digging-into-it/rn7xqef2w">couldn’t resist a pun</a>:</p> <blockquote> <p>Could picking your nose lead to dementia? Australian researchers are digging into it.</p> </blockquote> <p>Yet if we look at the research study behind these news reports, we may not need to be so concerned. The evidence connecting nose picking with the risk of dementia is still rather inconclusive.</p> <p><strong>What prompted these headlines?</strong></p> <p>Queensland researchers published <a href="https://www.nature.com/articles/s41598-022-06749-9">their study</a> back in February 2022 in the journal Scientific Reports.</p> <p>However, the results were not widely reported in the media until about eight months later, following a <a href="https://news.griffith.edu.au/2022/10/28/new-research-suggests-nose-picking-could-increase-risk-for-alzheimers-and-dementia/">media release</a> from Griffith University in late October.</p> <p>The media release had a similar headline to the multiple news articles that followed:</p> <blockquote> <p>New research suggests nose picking could increase risk for Alzheimer’s and dementia</p> </blockquote> <p>The media release clearly stated the research was conducted in mice, not humans. But it did quote a researcher who described the evidence as “potentially scary” for humans too.</p> <p><strong>What the study did</strong></p> <p>The researchers wanted to learn more about the role of <em>Chlamydia pneumoniae</em> bacteria and Alzheimer’s disease.</p> <p>These bacteria have been found in brains of people with Alzheimer’s, although <a href="https://academic.oup.com/femspd/article/48/3/355/506227?login=true">the studies</a> were completed more than <a href="https://doi.org/10.1007/s004300050071">15 years ago</a>.</p> <p>This bacteria species can cause respiratory infections such as pneumonia. It’s not to be confused with the chlamydia species that causes sexually transmitted infections (that’s <em>C. trachomatis</em>).</p> <p>The researchers were interested in where <em>C. pneumoniae</em> went, how quickly it travelled from the nose to the brain, and whether the bacteria would create a hallmark of Alzheimer’s disease found in brain tissue, the amyloid β protein.</p> <p>So they conducted a small study in mice.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=432&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=432&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=432&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=543&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=543&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/493175/original/file-20221103-22-znvia5.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=543&amp;fit=crop&amp;dpr=3 2262w" alt="White mouse in open cage with raised nose" /></a><figcaption><span class="caption">The study, which was conducted in mice, didn’t mention nose picking.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-photo/funny-curious-white-rat-looking-out-402796495">Shutterstock</a></span></figcaption></figure> <p>The researchers injected <em>C. pneumoniae</em> into the noses of some mice and compared their results to other mice that received a dose of salty water instead.</p> <p>They then waited one, three, seven or 28 days before euthanising the animals and examined what was going on in their brains.</p> <p><strong>What the study found</strong></p> <p>Not surprisingly, the researchers detected more bacteria in the part of the brain closest to the nose in mice that received the infectious dose.

Cold homes increase the risk of severe mental health problems – new study

<p>Concerns about <a href="https://theconversation.com/energy-crisis-the-uk-is-still-heading-for-widespread-fuel-poverty-despite-the-governments-price-cap-190290" target="_blank" rel="noopener">fuel poverty</a> and people not being able to heat their homes adequately are not new in the UK, but these worries have been <a href="https://www.theguardian.com/uk-news/2022/oct/26/warm-banks-open-wolverhampton-cost-of-living-crisis" target="_blank" rel="noopener">heightened</a> by significant increases in energy costs and the <a href="https://theconversation.com/the-cost-of-living-crisis-has-been-many-years-in-the-making-but-politicians-on-both-sides-ignore-this-189483" target="_blank" rel="noopener">cost-of-living crisis</a>. And as winter approaches, things are about to get a lot worse.</p> <p>Despite a relatively mild climate, the UK has higher levels of excess winter deaths – deaths associated with cold weather – than <a href="https://linkinghub.elsevier.com/retrieve/pii/S0140673614621140" target="_blank" rel="noopener">many colder countries</a>. This greater exposure to cold, despite milder weather, is related to poor housing quality, the high cost of heating homes and poverty.</p> <p>We know quite a lot about how living in a home that you can’t keep warm enough affects your physical health. Colder temperatures <a href="https://www.instituteofhealthequity.org/resources-reports/the-health-impacts-of-cold-homes-and-fuel-poverty/the-health-impacts-of-cold-homes-and-fuel-poverty.pdf" target="_blank" rel="noopener">suppress the immune system</a>, for example. But we know relatively little about the effects on mental health. <a href="https://doi.org/10.1016/j.socscimed.2022.115461" target="_blank" rel="noopener">Our new research</a> shows that living in a cold home is a significant mental health risk.</p> <p>Living in a cold home can affect your mental health in several ways. For many, heating costs are a source of stress and financial strain. Not being able to keep your home and family comfortably warm reduces feelings of control and autonomy over your environment. People who are unable to heat their home often adopt coping mechanisms that <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1365-2524.2005.00558.x" target="_blank" rel="noopener">limit socialising</a> – for example, not inviting friends over and going to bed early to keep warm. And many people are just worn down by the drudgery of a whole winter of being uncomfortably cold.</p> <p>Using <a href="https://www.understandingsociety.ac.uk/" target="_blank" rel="noopener">data</a> from a large representative sample of adults in the UK, we followed people over many years and tracked the effect of being unable to keep your home warm on mental health.</p> <p>When people’s homes became cold, their risk of severe mental distress significantly increased. For people who previously had no mental health problems, the odds of severe mental distress doubled when they had a cold home, while for those who had some (but not severe) mental health symptoms, the risk tripled (see chart below). We found these effects even after taking into account many other factors associated with mental health, including income.</p> <p><strong>Odds of reporting severe mental distress following transition into cold housing compared to those who remained in warm homes</strong></p> <figure class="align-center "><img src="https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=483&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=483&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=483&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=607&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=607&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/492381/original/file-20221028-61968-sxkqgr.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=607&amp;fit=crop&amp;dpr=3 2262w" alt="" /><figcaption><span class="attribution">author provided</span></figcaption></figure> <p>Sadly, the risk of living in a cold home differs greatly across the UK population. Lone parents and people who are unemployed or long-term sick are much more likely to live in cold homes. There is also significant inequality across ethnic groups – more than 12% of black people live in cold homes compared with under 6% of white British people, for example. Those who rent rather than own their home are also far more likely to live in cold homes, for social renters this is despite the, on average, <a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1088447/EHS_Housing_quality_and_condition_report_2020.pdf" target="_blank" rel="noopener">higher quality and</a><a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1091144/Energy_Report_2020_revised.pdf" target="_blank" rel="noopener">efficiency</a> of social rented homes.</p> <p>Putting on another jumper won’t be enough to get many in the UK through the coming winter. And mental health distress is just one consequence. Cold homes cause issues with significant personal and societal costs – from individual health effects to the increased pressure on the NHS, as well as broader economic loss due to missed work. Rishi Sunak’s new government needs to help people live in adequately warm homes this winter. But how?</p> <p>The older age of housing in the UK is <a href="http://www.instituteofhealthequity.org/projects/the-health-impacts-of-cold-homes-and-fuel-poverty" target="_blank" rel="noopener">heavily implicated</a> in the UK’s high levels of cold. Support for energy efficiency improvements is therefore a possible means of reducing cold homes. This will also mean tackling the so-called “split incentive” in the private rented sector, which houses a significant proportion of households. The split incentive refers to the challenge of the benefits of improvements not being experienced by the property owners but by tenants, reducing the incentive for owners to invest. This results in poorer quality and more expensive homes for renters.</p> <p><strong>Heat or eat? Most can’t afford either</strong></p> <p>The high proportion of cold homes in the social housing sector – despite having the best average energy efficiency due to insulation and building types (flats) – shows that energy efficiency improvements alone will not eliminate cold. <a href="https://www.resolutionfoundation.org/publications/the-living-standards-outlook-2022/" target="_blank" rel="noopener">Incomes in the UK are falling</a>. Benefit levels are <a href="https://theconversation.com/raising-benefits-in-line-with-earnings-will-make-the-poor-worse-off-heres-why-192880" target="_blank" rel="noopener">painfully low</a> and worsened by policies including the benefit cap, two-child limit and sanctions. Years of cuts and <a href="https://www.jrf.org.uk/file/59072/download?token=acsEgZp7&amp;filetype=briefing" target="_blank" rel="noopener">below inflation rises</a> mean that the term “heat or eat”, used to describe difficult spending decisions for low-income households, is now out of date, as <a href="https://www.jrf.org.uk/file/59191/download?token=PCFIM8W9&amp;filetype=briefing" target="_blank" rel="noopener">many can afford neither</a>.</p> <p>The combination of low household incomes with surging energy costs has created devastating pressure on household budgets.

Being stressed out before you get COVID increases your chances of long COVID. Here’s why

<p>Stress is part and parcel of modern life. When we’re on the verge of a new challenge or a significant event, we can experience stress mixed with excitement and a sense of challenge. This form of “good” stress, or <a href="https://www.verywellmind.com/what-you-need-to-know-about-eustress-3145109" target="_blank" rel="noopener">eustress</a>, is important for growth, development, and achievement.</p> <p>However, prolonged stress and overwhelming or traumatic events can negatively impact our health. These forms of “bad” stress – or distress – can make us sick, depressed, anxious and over the long term, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3341916/" target="_blank" rel="noopener">increase our risk</a> of heart disease, stroke, type 2 diabetes, dementia and even <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6877941" target="_blank" rel="noopener">cancer</a>.</p> <p>Distress can also affect our ability to <a href="https://medlineplus.gov/postcovidconditionslongcovid.html" target="_blank" rel="noopener">fully recover</a> from COVID. Ongoing symptoms for a month or more is referred to as long COVID. Those affected can experience fatigue, brain fog, shortness of breath, loss of taste and smell, difficulty sleeping, anxiety and/or depression. For some, these symptoms can last for many months or even years, making it impossible to return to pre-COVID life.</p> <p>In a <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2796097" target="_blank" rel="noopener">Harvard University study</a> published last month, people suffering psychological distress in the lead up to their COVID infection had a greater chance of experiencing long COVID. The researchers found those with two types of distress (depression, probable anxiety, perceived stress, worry about COVID, and loneliness) had an almost 50% greater risk of long COVID than other participants.</p> <p>So how might distress impact the body’s ability to fight infection?</p> <p><strong>First, we need to look at inflammation</strong></p> <p><a href="https://stories.uq.edu.au/imb/the-edge/inflammation/what-is-inflammation/index.html" target="_blank" rel="noopener">Inflammation</a> is the body’s way of responding to an infection or injury.</p> <p>When the <a href="https://medlineplus.gov/ency/article/000821.htm" target="_blank" rel="noopener">immune system</a> encounters a virus, for example, it launches an attack to neutralise infected cells and store a memory of that virus so it can respond faster and more effectively the next time.</p> <p>Many things can cause inflammation, including bacteria and viruses, injuries, toxins and chronic stress.</p> <p>The body has many different responses to inflammation, including redness, heat, swelling and pain. Some inflammatory responses can occur silently within the body, without any of these typical symptoms. At other times, inflammation can mobilise energy resources to cause exhaustion and fever.</p> <p>During inflammation, immune cells release substances known as inflammatory mediators. These chemical messengers cause small blood vessels to become wider (dilate), allowing more blood to reach injured or infected tissue to help with the healing process.</p> <p>This process can also irritate nerves and cause pain signals to be sent to the brain.</p> <p><strong>What does distress have to do with inflammation?</strong></p> <p>In the short term, stress <a href="https://newsinhealth.nih.gov/2021/01/feeling-stressed" target="_blank" rel="noopener">causes</a> the release of hormones that suppress inflammation, ensuring the body has enough energy resources available to respond an immediate threat.</p> <p>However, when experienced over an extended period of time, stress itself can cause low grade “silent” inflammation. Chronic distress and related mental health conditions such as anxiety and depression, are all associated with elevated levels of inflammatory mediators. In fact, the repeated exposure to mild, unpredictable stress is enough to elicit an inflammatory response.</p> <figure class="align-center "><em><img src="https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/490261/original/file-20221018-15212-eoxhg1.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=3 2262w" alt="Fatigued woman rests her head against a wall" /></em><figcaption><em><span class="caption">Repeated exposure to stress can produce an inflammatory response.</span> <span class="attribution"><a class="source" href="https://unsplash.com/photos/pV_ixbLn4QU" target="_blank" rel="noopener">Stacey Garrielle Koenitz Rozells/Unsplash</a></span></em></figcaption></figure> <p>Pre-clinical (lab-based) <a href="https://www.nature.com/articles/mp2013155" target="_blank" rel="noopener">studies</a> have shown chronic mild stress can cause depression-like behaviour by promoting inflammation, including activating immune cells in the brain (microglia).

However if given after the event, the anti-inflammatories were ineffective.</p> <p>When inflammation is ongoing, such as with extended periods of distress, the immune system changes the way it responds by reprogramming the immune cells. Effectively, it switches to “low surveillance mode”. In this way, it remains active throughout the body, but downgrades its responsiveness to new threats.</p> <p>Because of this, the response may be slower and less effective. Consequently, the process of recovery can take longer. For a virus like COVID, it’s possible that prior exposure to distress may similarly impair the body’s ability to fight the infection and increase the risk of long COVID.</p> <p><strong>How might distress affect recovery from COVID?</strong></p> <p>There is still much to learn about how COVID infection affects the body and how psychological factors can impact clinical outcomes in the short and long term.</p> <p>COVID has far-reaching effects across multiple body systems, affecting the lungs and heart to the greatest degree, and increasing the risk of blood clotting and stroke.</p> <p>Because the virus resides within human cells, an immune system switched to “low surveillance mode” as a result of psychological distress may miss early opportunities to destroy infected tissues. The virus can then gain an advantage over the defence (immune) system.</p> <p>Conversely, distress can suppress the early response, tipping the balance in favour of the invader.</p> <figure class="align-center "><em><img src="https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=411&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=411&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=411&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=516&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=516&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/490269/original/file-20221018-23-yyoxhq.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=516&amp;fit=crop&amp;dpr=3 2262w" alt="Man sits on a ledge over a busy street" /></em><figcaption><span class="caption"><em>An immune system already switched to low surveillance mode might miss early opportunities to destroy the virus.</em></span><em> <span class="attribution"><a class="source" href="https://unsplash.com/photos/kFVmYjK6hZ8" target="_blank" rel="noopener">Whoislimos/Unsplash</a></span></em></figcaption></figure> <p><strong>So what can we do about it?</strong></p> <p>Vaccines work by helping to train the immune system to find the target sooner, giving the immune system the advantage.</p> <p>Behavioural interventions that improve the ability to cope with stress <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9075982/" target="_blank" rel="noopener">decrease inflammation</a> and may help to enhance the immune response to COVID.</p> <p>It’s also important to be aware that exposure to COVID <a href="https://www.sciencedirect.com/science/article/pii/S0889159120316068" target="_blank" rel="noopener">increases the risk</a> of depression, anxiety or other mental health conditions.

Leaked email advises landlords to increase rent amid housing crisis

<p dir="ltr">A real estate agency in Brisbane has come under fire over a leaked email in which landlords were advised to consider raising rents by more than 20 percent amid Australia’s worsening rental crisis.</p> <p dir="ltr">The email, sent by Ray White East End, asked landlords to consider whether their properties were being “under-rented” and advised them to increase rents by “above 20 percent” - more than double the rate of inflation - with potential earnings of an extra $10,000 a year.</p> <p dir="ltr">“Our property managers have been reviewing all our lease renewals and on average recommending a 17% rent increase on the leases renewed in October &amp; November this year,” the email said, per <em><a href="https://www.theguardian.com/australia-news/2022/oct/17/brisbane-real-estate-agency-advises-landlords-to-increase-rents-by-over-20-amid-housing-crisis" target="_blank" rel="noopener">The Guardian</a></em>.</p> <p dir="ltr">“As we are planning December lease renewals, the average lease renewal recommendation is above 20%. This can be as much as $10,000 per year in additional rental income.”</p> <p dir="ltr">The agency said that “many landlords are not being provided with the information to make an informed decision” about rent increases, claiming that landlords were being advised to sign long-term leases with increases of $5 to $20 a week.</p> <p dir="ltr">The email also said that most tenants “are agreeable” to the increases and would understand that it is “fair and reasonable” based on what is available on the market.</p> <p dir="ltr">“On average, apartments in West End/Highgate Hill/South Brisbane/Brisbane CBD are renting for one bedroom $480 to $520+ [a week and for] two bedrooms $675 to $850+ [a week],” the email said.</p> <p dir="ltr">“If you are not achieving these rents (at a minimum), you should be asking why?”</p> <p dir="ltr">It comes as the Queenlsand government prepares to hold a housing summit to address rising homlessness and rental stress across the state.</p> <p dir="ltr">Penny Carr, the chief executive at advocacy organisation Tenants Queensland, said the email was an example of “opportunistic price-gouging” that is happening across Australia at the moment.</p> <p dir="ltr">“Rents are unaffordable for people at the moment and tenants are having to absorb increases because of fear of not finding another property or becoming homeless,” she said.</p> <p dir="ltr">“We should only allow rent increases above CPI if they’re justifiable and there’s been major work to the property or something’s had to be replaced.”</p> <p dir="ltr">Ms Carr said rent increases have been due to vacancy rates and supply and demand, and that the email dispels the myth that a land tax proposed by the government last year for interstate investors is to blame.</p> <p dir="ltr">Meanwhile, Ray White East End principal realtor Luke O’Kelly said rental affordability relies on investors.</p> <p dir="ltr">“Over the past 12 months, Brisbane has had some of the strongest population growth in the country and this has most clearly shown up in rental growth,” Mr O’Kelly said.</p> <p dir="ltr">“Right now, Brisbane doesn’t have enough homes for those that want to live here … with rents rising so quickly, Brisbane needs more property investors.”</p> <p dir="ltr">Fiona Caniglia, executive director of not-for-profit housing and homelessness organisation Q Shelter, said the timing of the email couldn’t be worse.</p> <p dir="ltr">“It is disappointing to hear this the week of the emergency housing summit to be honest,” she told <em><a href="https://www.news.com.au/finance/real-estate/renting/dont-have-enough-homes-rental-agency-ray-white-tries-to-increase-rent-by-20-per-cent/news-story/e4ff2ab4807fffe3b50b90fe81069156" target="_blank" rel="noopener">news.com.au</a></em>.</p> <p dir="ltr">“We already know that many vulnerable Queenslanders are struggling to secure a rental property in the first place.”</p> <p dir="ltr">“There are record numbers of people showing up for the small number of properties listed right across Queensland. Such an increase will only benefit those on higher incomes and will of course again negatively affect vulnerable Queenslanders, forcing more people into homelessness.”</p> <p dir="ltr">Ray White’s chief economist Nerida Conisbee defended the email in a statement shared with the outlet, saying that the market is currently ideal for investors.</p> <p dir="ltr">“Right now, Brisbane doesn’t have enough homes for those that want to live here,” she said.</p> <p dir="ltr">“This is making it tough for renters but does make it a good place to invest. While red hot house price growth is unlikely to start up again in the near future, yields are increasing as rents rise.”</p> <p dir="ltr">With Australians paying an extra $7.1 billion in rent over the past year and the average renter spending $62 more a week than this time last year, Greens housing and homelessness spokesperson Max Chandler-Mather said the email showed that urgent action is needed.</p> <p dir="ltr">“It’s this sort of flagrant price-gouging that demonstrates exactly why we need a national two-year freeze on rent increases,” he said.</p> <p><span id="docs-internal-guid-605890c5-7fff-934e-a79a-b24009315c32"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

Rent crisis? Average rents are increasing less than you might think

<p>You wouldn’t know it from the pages of our daily newspapers, but the rate of growth in rents has been pretty modest.</p> <p>Not everywhere, not for everyone, but for most Australians who rent.</p> <p>According to the most recent count used by the Bureau of Statistics to compile the consumer price index, rents increased by only <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/consumer-price-index-australia/latest-release#overview" target="_blank" rel="noopener">1.6%</a> in the year to June.</p> <p>By comparison, wages climbed <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/wage-price-index-australia/latest-release" target="_blank" rel="noopener">2.6%</a>.</p> <p>Higher increases in other prices pushed the overall consumer price index up <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/consumer-price-index-australia/latest-release" target="_blank" rel="noopener">6.1%</a>.</p> <p>Rent decreases during COVID mean that over the past five years the total increase has been just 1.5%.</p> <p>Average rents are barely any higher than they were at the start of COVID.</p> <hr /> <p><iframe id="GnFV0" class="tc-infographic-datawrapper" style="border: initial none initial;" src="https://datawrapper.dwcdn.net/GnFV0/2/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>The Bureau gets its data direct from the computers of real estate agents, state housing authorities and the Department of Defence (for Darwin).</p> <p>It covers rent actually paid, for a “<a href="https://www.abs.gov.au/statistics/detailed-methodology-information/concepts-sources-methods/consumer-price-index-concepts-sources-and-methods/2018/price-collection" target="_blank" rel="noopener">matched sample</a>” of dwellings, meaning it refers to the same dwellings each quarter so as to record genuine price changes.</p> <p><strong>Actual versus advertised rents</strong></p> <p>In contrast, the media (and some <a href="https://everybodyshome.com.au/resources/housing-criticalthe-role-of-housing-in-solving-critical-skill-shortages-across-the-regions/" target="_blank" rel="noopener">interest groups</a>) prefer to focus on the data for “advertised” or asking rents. These have been growing more strongly than the overall mass of rents paid.</p> <p>Nationwide, advertised rents climbed <a href="https://www.corelogic.com.au/news-research/news/2022/residential-rents-hit-record-highs-as-national-vacancy-rates-plummet" target="_blank" rel="noopener">8.2%</a> in the year to June, and by almost 18% over the five years to June on CoreLogic’s data.</p> <p>But advertised rents are only a tiny fraction of the rents actually paid. Not all properties get advertised. Advertised rents don’t always match up with the agreed rent. Most renters remain on existing contracts.</p> <p>Although advertised rents might be expected to relate to overall rents over time, they are not necessarily representative of the entire market.</p> <p>Our main concern ought to be what has happened to low-income renters.</p> <p><strong>Low increases for low-income renters</strong></p> <p>Australia’s lowest-income renters receive rent assistance, which is pretty frugal. Single renters get no more than <a href="https://www.servicesaustralia.gov.au/how-much-rent-assistance-you-can-get?context=22206" target="_blank" rel="noopener">$73 a week</a>, and very large families up to $97.</p> <p>But the typical rent paid by Australians on rent assistance hasn’t increased much. Over the year to June, the median rent for rent assistance recipients climbed by 1% – roughly $5 per week. Over the past five years it has increased 9% – somewhat less than the increase in the consumer price index of 10.7%.</p> <p>Over the longer term, low-income rents have increased more sharply. Households in the bottom 40% of income distribution used to spend around 22% of their after-tax income on rent, and now spend about 30%, down from a peak of 32%.</p> <hr /> <p><iframe id="pRiMR" class="tc-infographic-datawrapper" style="border: initial none initial;" src="https://datawrapper.dwcdn.net/pRiMR/2/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>If there is a crisis in rents, the figures suggest it is not widespread.</p> <p>Rents in locations including Perth and Darwin are climbing much more strongly than others as they come off long periods of negative rent growth.</p> <p>The growth in asking rents is most pronounced away from the cities, in particular in holiday and tree-change destinations such as Richmond-Tweed (including Byron Bay), Gold Coast, Sunshine Coast and Wide Bay.</p> <p>Some were experiencing strong growth in asking rents before COVID, which accelerated through COVID.</p> <hr /> <p><iframe id="JMbb7" class="tc-infographic-datawrapper" style="border: initial none initial;" src="https://datawrapper.dwcdn.net/JMbb7/2/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>Other regions, including parts of Sydney and Melbourne, have experienced subdued or <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/consumer-price-index-australia/latest-release#overview" target="_blank" rel="noopener">negative</a> growth.</p> <p>Across all renting households we are yet to see any serious growth.

Rapidly increasing climate change poses a rising threat to mental health

<p>Climate change poses serious risks to mental well-being. For the first time, a <a href="https://www.ipcc.ch/report/sixth-assessment-report-working-group-ii/">new climate report</a> by the Intergovernmental Panel on Climate Change (IPCC) has assessed how climate change is having widespread and cumulative effects on mental health globally. </p> <p>Over the past decade, research and public interest on the effects of climate change on mental health have been increasing, as the number of individuals and communities exposed and vulnerable to climate change hazards grows. </p> <p>Weather and climate extremes such as storms, floods, droughts, heat events and wildfires can be traumatic and have immediate impacts on mental health. Slow onset events like changing seasonal and environmental norms, sea level rise and ice patterns can also affect people’s mental well-being.</p> <p>Growing evidence confirms that the consequences of rapid, widespread and pervasive climate events may include <a href="https://doi.org/10.1016/j.janxdis.2020.102263">anxiety</a>, <a href="https://changingclimate.ca/health-in-a-changing-climate/chapter/4-0/">PTSD</a>, <a href="https://doi.org/10.1038/s41558-018-0222-x">higher rates of suicide</a>, <a href="https://doi.org/10.1016/j.janxdis.2020.102237">a diminished sense of well-being (stress, sadness)</a>, <a href="https://doi.org/10.1016/S2542-5196(20)30144-3">ecological grief</a>, a rise in domestic violence, <a href="https://doi.org/10.1186/s12889-015-1874-3">cultural erosion</a> and diminished social capital and social relations.</p> <p>As scientists who contributed to the latest IPCC report <a href="https://www.ipcc.ch/report/sixth-assessment-report-working-group-ii/">Climate Change 2022: Impacts, Adaptation and Vulnerability</a>, we are pleased that this Sixth Assessment Report (AR6) assesses climate change impacts on mental health for the first time in detail, representing a major advancement and new contribution. </p> <h2>Significant threats</h2> <p>The Earth will <a href="https://www.ipcc.ch/report/sixth-assessment-report-working-group-i/">likely reach 1.5 C of warming above pre-industrial levels by 2040</a>under intermediate and high greenhouse gas emissions scenarios, bringing with it <a href="https://www.ipcc.ch/sr15/chapter/spm/">higher temperatures on land and in the ocean, declining sea ice, more heat waves, more rainfall in some regions and a greater chance of drought in others</a>. </p> <p>With increasing exposures to these hazards comes greater incidences of negative mental health outcomes. The findings outlined in the report confirm the depth, breadth and significance of the ways climate change impacts mental health. This synthesis of global research indicates that these negative mental health outcomes are on the rise and unequally distributed due to climate change. </p> <p>Here are three things that the latest IPCC report tells us about climate change and mental health in North America.</p> <p><strong>1. There is greater scientific understanding about the ways that climate change negatively impacts mental health.</strong></p> <p>When the <a href="https://www.ipcc.ch/report/ar5/wg2/">IPCC Fifth Assessment Report</a> (AR5) was published in 2014, there was emerging yet limited research on mental health outcomes. The report mentioned that climate change could affect mental health, but there wasn’t enough published research available then to fully assess its impacts. </p> <p>As the volume of research on <a href="https://doi.org/10.1016/j.envres.2021.111205">climate change and mental health has grown</a>, this new report is now able to assess its impact. Researchers have been able to examine how both climate and weather extremes such as storms, floods, droughts and fires and slower-onset climate changes such as warming temperatures and changing environmental norms interact with people’s vulnerabilities such as socio-economic inequities, age, gender, identity, occupation and health and lead to a diverse range of negative mental health outcomes.</p> <p>For example, a <a href="https://doi.org/10.1371/journal.pone.0119929">synthesis of global literature</a> found that those exposed to flooding events — such as the floods in southern British Columbia in 2021, in Ottawa in 2019 and Alberta in 2013 — experience PTSD, depression and anxiety in the short term and have elevated risks for these mental health outcomes in the long term. Similar mental health outcomes were found for those <a href="https://doi.org/10.17269/s41997-018-0070-5">exposed to wildfires and related smoke</a>, such as the wildfires in the Northwest Territories in 2014, Fort McMurray, Alta., in 2016 and Lytton, B.C., in 2021. </p> <p>Our <a href="https://doi.org/10.1016/j.socscimed.2012.03.043">own work</a> with Inuit in Nunatsiavut, Labrador, demonstrates the ways in which slower, cumulative impacts from rising temperatures, declining sea ice and changing seasonal, animal and plant patterns disrupt land-based activities and livelihoods, <a href="https://doi.org/10.1007/s10584-013-0875-4">leading to negative consequences for mental and emotional well-being</a>. This includes <a href="https://doi.org/10.1016/j.emospa.2011.08.005">strong emotional reactions</a> (stress, anger, fear and distress), <a href="https://doi.org/10.1038/s41558-018-0092-2">ecological grief</a> and loss, expressions of anxiety and depression and <a href="http://www.lamentfortheland.ca/">loss of cultural knowledge and place-based identities and connections</a>.</p> <p><strong>2. The mental health impacts of climate change are unequally distributed.</strong></p> <p>Climate change works across intersecting social determinants of health — factors such as age or gender that influence health and how people live — to disproportionately affect certain groups.</p> <p>For example, AR6 demonstrates that some people and communities are most at risk for increasingly worsening mental health outcomes, due to their proximity to the hazard, their reliance on the environment for livelihood and culture and their socio-economic status:</p> <ul> <li><a href="https://doi.org/10.1016/j.socscimed.2017.01.009">Agricultural communities</a> already experiencing drought or changing environmental conditions. </li> <li>People living in areas exposed to <a href="https://doi.org/10.17269/s41997-018-0070-5">wildfires</a> and <a href="https://doi.org/10.1371/journal.pone.0119929">floods</a>.</li> <li><a href="https://doi.org/10.1088/1748-9326/ab68a9">Indigenous Peoples</a> and those closely dependent on the natural environment for livelihoods and culture </li> <li><a href="https://changingclimate.ca/health-in-a-changing-climate/">Women, the elderly</a>, <a href="https://dx.doi.org/10.2139/ssrn.3918955">children and young people</a> and those already experiencing <a href="https://www.apa.org/news/press/releases/2017/03/mental-health-climate.pdf">chronic physical and mental health issues</a>.</li> </ul> <p><strong>3. It’s not too late to promote resilience.</strong></p> <p>Climate change is not a distant threat. It’s a growing reality. Urgent action is needed to protect the mental health of individuals, communities and health systems under rapid climate change and support individual and community resilience and well-being. Resilience can be enhanced through climate-specific mental health outcomes training and policy action, which support health systems to enhance individual and community mental health and well-being. </p> <p>For example, the American Psychological Association outlines strategies to build personal resilience, including building belief in one’s own reslience, fostering optimism, cultivating coping strategies, finding sources of personal meaning, finding social support networks (family, friends, organized groups), fostering and upholding a connection to place and maintaining connections to one’s culture.</p> <p>Incorporating climate-specific training in education and for physicians, nurses, psychologists, psychiatrists, counsellors and allied health professionals, is essential for building climate-literate health professionals capable of supporting individual and community resilience and for preparing health systems to better serve those experiencing climate-sensitive mental health challenges. </p> <p>Finally, <a href="https://changingclimate.ca/health-in-a-changing-climate/chapter/10-0/">health systems and health authorities</a> must take measures to assess and enhance health system readiness to deal with growing mental health needs and increase disaster planning and training, to further support individual and community resilience to climate change.</p> <h2>Moving forward</h2> <p>Based on the available evidence, the mental health impacts from climate change are already widespread and likely to worsen. Even with immediate and strong action towards mitigation and adaptation, climate change will continue to be a serious threat. It is critical that we understand the serious risks that climate change poses to mental well-being and take urgent action to support health systems and enhance individual and community mental health and resilience within a changing climate. </p> <p>Although more evidence is needed to determine the most effective programs and policies to reduce negative mental health outcomes from climate change, the effectiveness of individual and group therapy, place-specific and culturally responsive mental health infrastructure and <a href="https://doi.org/10.1186/s12199-019-0822-8">nature-based therapies</a> have been well-proven in other areas, and show promise. </p> <p>Protecting individual and community mental health and well-being requires action from all levels of government and health authorities and integrating a mental health lens and a “<a href="https://www.cmaj.ca/content/192/3/E61">Health in All Policies</a>” approach. Major <a href="https://changingclimate.ca/health-in-a-changing-climate/chapter/10-0/">co-benefits for health and well-being </a>in general, and mental health in particular, can arise when decision-makers in all sectors consider and promote health and health equity through adaptation strategies, while taking urgent measures to mitigate greenhouse gas emissions and limit global warming to 1.5 C.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/rapidly-increasing-climate-change-poses-a-rising-threat-to-mental-health-says-ipcc-177906" target="_blank" rel="noopener">The Conversation</a>. </em></p>
