What washing machine settings can I use to make my clothes last longer?

<a href="https://theconversation.com/profiles/alessandra-sutti-1513345">Alessandra Sutti</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/amol-patil-1513347">Amol Patil</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/maryam-naebe-1513346">Maryam Naebe</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Orbiting 400 kilometres above Earth’s surface, the astronauts on the International Space Station live a pretty normal social life, if not for one thing: they happily wear their unwashed clothes <a href="https://www.nasa.gov/centers-and-facilities/glenn/nasa-glenn-interns-take-space-washing-machine-designs-for-a-spin/">for days and weeks at a time</a>. They can’t do their laundry <a href="https://www.esa.int/Enabling_Support/Space_Engineering_Technology/Keeping_your_underwear_clean_on_the_Moon">just yet</a> because water is scarce up there. But down here on Earth, washing clothes is a large part of our lives. <a href="https://bigee.net/media/filer_public/2013/03/28/bigee_domestic_washing_machines_worldwide_potential_20130328.pdf">It’s estimated</a> that a volume of water equivalent to 21,000 Olympic swimming pools is used every day for domestic laundry worldwide. Fibres from our clothes make their way into the environment via the air (during use or in the dryer), water (washing) and soil (lint rubbish in landfill). Most of this fibre loss is invisible – we often only notice our favourite clothing is “disappearing” when it’s too late. How can you ensure your favourite outfit will outlast your wish to wear it? Simple question, complex answer. <h2>Washing machines are not gentle</h2> When you clean the filters in your washing machine and dryer, how often do you stop to think that the lint you’re holding <a href="https://theconversation.com/uk-laundry-releases-microfibres-weighing-the-equivalent-of-1-500-buses-each-year-199712">was, in fact, your clothes</a>? Laundering is harsh on our clothes, and <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0250346">research confirms this</a>. Several factors play a role: the type of washing machine, the washing cycle, detergents, temperature, time, and the type of fabric and yarn construction. There are two types of domestic washing machines: top-loader and front-loader. Mechanical agitation (the way the machine moves the clothes around) is one of the things that helps ease dirt off the fabric. Top-loaders have a vertical, bucket-like basket with a paddle, which sloshes clothes around in a large volume of water. Front-loaders have a horizontal bucket which rotates, exposing the clothes to a smaller volume of water – it takes advantage of gravity, not paddles. Top-loading machines <a href="https://link.springer.com/article/10.1007/s12541-010-0047-7">tend to be more aggressive</a> towards fabrics than front-loaders due to the different mechanical action and larger volumes of water. Washing machine panels also present many choices. Shorter, low-temperature programs <a href="https://clevercare.info/more-eco-temperature-tips">are usually sufficient for everyday stains</a>. Choose longer or <a href="https://iprefer30.eu/animations/UK/wash-brochure-uk.pdf">high-temperature programs</a> only for clothing you have concerns about (healthcare uniforms, washable nappies, etc.). Generally, washing machine programs are carefully selected combinations of water volume, agitation intensity and temperature recommended by the manufacturer. They take into consideration the type of fabric and its level of cleanliness. Select the wrong program and you can say goodbye to your favourite top. For example, high temperatures or harsh agitation may cause some fibres to weaken and break, causing holes in the garment. <h2>Some fabrics lose fibres more easily than others</h2> At a microscopic level, the fabric in our clothes is made of yarns – individual fibres twisted together. The nature and length of the fibres, the way they are twisted and the way the yarns form the fabric can determine how many fibres will be lost during a wash. In general, if you want to lose fewer fibres, you should wash less frequently, but some fabrics are affected more than others. Open fabric structures (knits) with loose yarns <a href="https://www.nature.com/articles/s41598-021-98836-6">can lose more fibres</a> than tighter ones. Some sports clothing, like running shirts, are made of continuous filament yarn. These fibres are less likely to come loose in the wash. Cotton fibres are only a few centimetres long. Twisted tightly together into a yarn, they can still escape. Wool fibres are also short, but have an additional feature: scales, which make wool clothes much more delicate. Wool fibres can come loose like cotton ones, but also tangle with each other during the wash due to their scales. This last aspect is what causes wool garments to shrink when <a href="https://journals.sagepub.com/doi/abs/10.1177/004051756403400303">exposed to heat</a> and agitation. <h2>Go easy on the chemicals</h2> The type of detergent and other products you use also makes a difference. Detergents contain a soap component, enzymes to make stains easier to remove at low temperature, and fragrances. Some contain harsher compounds, such as bleaching or whitening agents. Modern detergents are very effective at <a href="https://www.choice.com.au/home-and-living/laundry-and-cleaning/laundry-detergents/review-and-compare/laundry-detergents">removing stains such as food</a>, and you don’t need to use much. An incorrect choice of wash cycles, laundry detergent and bleaching additives could cause disaster. Certain products, like bleach, can <a href="https://site.extension.uga.edu/textiles/textile-basics/understand-your-fibers/">damage some fibres like wool and silk</a>. Meanwhile, research on <a href="https://www.sciencedirect.com/science/article/pii/S0269749120366872?via%3Dihub">fabric softeners and other treatments</a> <a href="https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0233332&type=printable">continues</a> – there’s no one-size-fits-all answer about their potential impact on our clothes. <h2>Just skip laundry day</h2> So, how to ensure your clothes last longer? The main tip is to wash them less often. When it’s time for a wash, carefully read and follow the care labels. In the future, our washing machines will <a href="https://www.teknoscienze.com/tks_article/trends-in-laundry-by-2030/">recognise fabrics and select the wash cycle</a>. For now, that’s our responsibility. And the next time you throw your shirt into the dirty laundry basket, stop. Think of the astronauts orbiting above Earth and ask yourself: if they can go without clean laundry for a few days, maybe I can too? (Although we don’t recommend just burning your dirty undies, either.)<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/224064/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <figure><iframe src="https://www.youtube.com/embed/C1j6KLP492E?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <a href="https://theconversation.com/profiles/alessandra-sutti-1513345">Alessandra Sutti</a>, Associate Professor, Institute for Frontier Materials, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/amol-patil-1513347">Amol Patil</a>, Research Engineer, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/maryam-naebe-1513346">Maryam Naebe</a>, Associate professor, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

We reviewed the health habits of centenarians. These 4 things could lead to a longer life

<a href="https://theconversation.com/profiles/zhaoli-dai-keller-1547476">Zhaoli Dai-Keller</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/perminder-sachdev-46869">Perminder Sachdev</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> The number of centenarians around the world rose from <a href="https://population.un.org/wpp/Download/Standard/Population/">151,000 in 2000</a> to 573,000 in 2021. People are living longer, and we can expect to see more people reach 100 in the years to come. Centenarians <a href="https://academic.oup.com/biomedgerontology/article/67A/4/395/623695">exemplify successful ageing</a>, often experiencing <a href="https://agmr.hapres.com/htmls/AGMR_1264_Detail.html">fewer chronic diseases</a> and maintaining independence in daily life well into their 90s. While <a href="https://link.springer.com/article/10.1186/s12979-016-0066-z">genetics contribute</a> to longevity, modifiable factors account for more than 60% <a href="https://pubmed.ncbi.nlm.nih.gov/14624729/">of successful aging</a>. But what sort of factors specifically contribute to living to 100? To find out, we reviewed lifestyle and health habits of centenarians and near-centenarians (those aged 95–99) worldwide. Our <a href="https://link.springer.com/article/10.1007/s11357-024-01247-4">recent review</a> included 34 observational studies published since 2000. Here are four key factors we found contribute to extreme longevity. <h2>1. A diverse diet with controlled salt intake</h2> Centenarians and near-centenarians typically had a balanced and diverse diet. We found, on average, they consumed between 57% and 65% of their energy intake from carbohydrates, 12% to 32% from protein, and 27% to 31% from fat. Their diets included staple foods (such as rice and wheat), fruits, vegetables, and protein-rich foods like poultry, fish and legumes, with moderate red meat consumption. This dietary pattern, similar to the <a href="https://pubmed.ncbi.nlm.nih.gov/29852087/">Mediterranean diet</a>, is linked to lower risks of <a href="https://doi.org/10.3390/ijerph14111364">physical function impairment</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/31685303/">death</a>. Most centenarians also preferred a low-salt diet. While only one study in our review measured the mean daily sodium intake, finding 1.6 grams, this was within the <a href="https://www.who.int/data/gho/indicator-metadata-registry/imr-details/3082#:%7E:text=A%20salt%20intake%20of%20less,much%20more%20salt%20than%20recommended">World Health Organization’s</a> recommendation of less than 2g of sodium per day (equivalent to about 5g of salt). The <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">traditional Okinawan diet</a>, known for its consumption by Japanese centenarians on Okinawa Island, contains an estimated 1.1g of sodium. We found higher salt intake (those who preferred salty food or added extra salt to meals) had a 3.6-fold increased risk of physical function impairment compared to those without a preference for salt. Practically, these findings suggest we should include plenty of wholegrains, root vegetables, beans, legumes, fruits and vegetables in our diet, minimise red meat consumption and opt for lean poultry, fish, and plant-based protein, and monitor salt in our food. <h2>2. Lower medication use</h2> Centenarians are not free from chronic conditions but typically develop them much later than average adults. More than half of the people in our review experienced common issues such as hypertension (high blood pressure), dementia, or cognitive impairment. We found people in our review took an average of 4.6 medications. The most frequently used medications included blood pressure medications and drugs for heart disease. This is similar to the results of <a href="https://doi.org/10.3390/jcm9051563">a large health register-based study</a> in Spain, which found centenarians took an average of 4.9 medications. Non-centenarians in this study took 6.7 medications on average. The fact centenarians appear to take fewer medications may indicate better health with fewer medical conditions. However, data on medication use is often self-reported and so may not be entirely accurate, especially among those with cognitive impairment. <a href="https://www.thelancet.com/journals/lanhl/article/PIIS2666-7568(24)00007-2/fulltext">Polypharmacy</a> is often defined as taking five or more medications simultaneously, and is common in older adults. Inappropriate polypharmacy is associated with <a href="https://www.nia.nih.gov/news/dangers-polypharmacy-and-case-deprescribing-older-adults">increased risks</a> of adverse events such as falls, cognitive impairment and hospitalisation, due to harmful drug interactions. While the type or number of prescribed medications may not be within a patient’s control, it’s important for doctors to <a href="https://link.springer.com/article/10.1186/s12875-017-0642-0">prescribe medications</a> only when necessary, fully inform patients about benefits and risks, and regularly review treatment plans. <h2>3. Getting good sleep</h2> Sleep quality and quantity <a href="https://newsinhealth.nih.gov/2013/04/benefits-slumber">affect</a> the immune system, stress hormones, and cardiometabolic functions such as obesity, high blood pressure, and diabetes. Good <a href="https://academic.oup.com/biomedgerontology/article/74/2/204/4837199">sleep</a> is associated with extended years of good health and reduced risks of chronic diseases. In our review, 68% of the centenarians were satisfied with their sleep quality. In a survey of adults’ sleep satisfaction in 13 countries in 2020, sleep satisfaction ranged from <a href="https://www.statista.com/statistics/1233775/adults-worldwide-satisfied-sleep-country/">29% to 67%</a>. The <a href="https://academic.oup.com/biomedgerontology/article/74/2/204/4837199">optimal sleep duration</a> is between seven and eight hours per night. Tips to <a href="https://www.mayoclinic.org/healthy-lifestyle/adult-health/in-depth/sleep/art-20048379">achieving better sleep</a> include keeping a regular sleep routine, creating a restful environment, exercising regularly and managing stress. <h2>4. Living environment</h2> More than 75% of the centenarians and near-centenarians in our review lived in rural areas. This is a pattern reflected in “<a href="https://www.bluezones.com/">blue zones</a>”, areas known for high concentrations of centenarians, such as Okinawa in Japan, Sardinia in Italy, the Nicoya Peninsula in Costa Rica, and Ikaria in Greece. This may be partly related to the connection between nature and health and wellbeing. For example, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6562165/">exposure to green space</a> has been associated with lower stress, depression, blood pressure, type 2 diabetes and heart disease, potentially increasing <a href="https://doi.org/10.1016/j.envint.2023.107785">life expectancy</a>. <h2>Other important factors</h2> We didn’t look at all lifestyle factors associated with longevity in our review. Research also shows <a href="https://www.sciencedirect.com/science/article/abs/pii/S053155650700143X">not smoking</a>, <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2802963">avoiding alcohol</a> or drinking moderately, staying <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3618983/">physically active</a> and maintaining <a href="https://doi.org/10.1098/rspb.2019.1991">social connections</a> are important for boosting a person’s chances of living to 100. Of course, adopting the lifestyle changes discussed in this article won’t guarantee you’ll reach the ripe old age of 100. And on the flip side, some centenarians have shared <a href="https://theconversation.com/why-you-should-never-take-nutrition-advice-from-a-centenarian-229159">questionable</a> health habits. But many older adults are seeking to adopt <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9092121/">healthier lifestyles</a> to prevent and manage chronic conditions, while health-care professionals are similarly recognising the value of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5638636/">lifestyle medicine</a>. The earlier you can adopt positive lifestyle changes and healthier habits, the better placed you’ll be to achieve a long and healthy life. Becoming a centenarian is a lifelong endeavour.<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/235100/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/zhaoli-dai-keller-1547476">Zhaoli Dai-Keller</a>, Honorary Senior Lecturer, School of Pharmacy, University of Sydney; Nutritional epidemiologist and Lecturer, School of Population Health, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/perminder-sachdev-46869">Perminder Sachdev</a>, Scientia Professor of Neuropsychiatry, Centre for Healthy Brain Ageing (CHeBA), School of Psychiatry, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Want to sleep longer? Adding mini-bursts of exercise to your evening routine can help

<a href="https://theconversation.com/profiles/jennifer-gale-1548741">Jennifer Gale</a>, <a href="https://theconversation.com/institutions/university-of-otago-1304">University of Otago</a> and <a href="https://theconversation.com/profiles/meredith-peddie-1548807">Meredith Peddie</a>, <a href="https://theconversation.com/institutions/university-of-otago-1304">University of Otago</a> Exercising before bed has <a href="https://www.sciencedirect.com/science/article/pii/S2352721815000157">long been discouraged</a> as the body doesn’t have time to wind down before the lights go out. But <a href="https://bmjopensem.bmj.com/content/10/3/e001774">new research</a> has found breaking up a quiet, sedentary evening of watching television with short bursts of resistance exercise can lead to longer periods of sleep. Adults spend almost one third of the 24-hour day sleeping. But the quality and length of sleep can affect long-term health. Sleeping too little or waking often in the night is associated with an <a href="https://academic.oup.com/sleep/article-lookup/doi/10.5665/sleep.1382">increased risk of heart disease</a> and <a href="https://diabetesjournals.org/care/article/33/2/414/27149/Quantity-and-Quality-of-Sleep-and-Incidence-of">diabetes</a>. Physical activity during the day can help improve sleep. However, <a href="https://www.sciencedirect.com/science/article/pii/S2352721815000157">current recommendations</a> discourage intense exercise before going to bed as it can increase a person’s heart rate and core temperature, which can ultimately disrupt sleep. <h2>Nighttime habits</h2> For many, the longest period of uninterrupted sitting happens at home in the evening. People also usually consume their largest meal during this time (or snack throughout the evening). Insulin (the hormone that helps to remove sugar from the blood stream) tends to be at a lower level in the evening than in the morning. Together these factors promote elevated blood sugar levels, which over the long term can be bad for a person’s health. Our <a href="https://journals.lww.com/acsm-msse/fulltext/2023/08000/breaking_up_evening_sitting_with_resistance.14.aspx">previous research</a> found interrupting evening sitting every 30 minutes with three minutes of resistance exercise reduces the amount of sugar in the bloodstream after eating a meal. But because sleep guidelines currently discourage exercising in the hours before going to sleep, we wanted to know if frequently performing these short bursts of light activity in the evening would affect sleep. <h2>Activity breaks for better sleep</h2> In our latest research, we asked 30 adults to complete two sessions based in a laboratory. During one session the adults sat continuously for a four-hour period while watching streaming services. During the other session, they interrupted sitting by performing three minutes of body-weight resistance exercises (squats, calf raises and hip extensions) every 30 minutes. After these sessions, participants went home to their normal life routines. Their sleep that evening was measured using a wrist monitor. Our research found the quality of sleep (measured by how many times they woke in the night and the length of these awakenings) was the same after the two sessions. But the night after the participants did the exercise “activity breaks” they slept for almost 30 minutes longer. Identifying the biological reasons for the extended sleep in our study requires further research. But regardless of the reason, if activity breaks can extend sleep duration, then getting up and moving at regular intervals in the evening is likely to have clear health benefits. <h2>Time to revisit guidelines</h2> These results add to <a href="https://linkinghub.elsevier.com/retrieve/pii/S1087079221001209">earlier work</a> suggesting current sleep guidelines, which discourage evening exercise before bed, may need to be reviewed. As the activity breaks were performed in a highly controlled laboratory environment, future research should explore how activity breaks performed in real life affect peoples sleep. We selected simple, body-weight exercises to use in this study as they don’t require people to interrupt the show they may be watching, and don’t require a large space or equipment. If people wanted to incorporate activity breaks in their own evening routines, they could probably get the same benefit from other types of exercise. For example, marching on the spot, walking up and down stairs, or even dancing in the living room. The key is to frequently interrupt evening sitting time, with a little bit of whole-body movement at regular intervals. In the long run, performing activity breaks may improve health by improving sleep and post-meal blood sugar levels. The most important thing is to get up frequently and move the body, in a way the works best for a person’s individual household.<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/234896/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jennifer-gale-1548741">Jennifer Gale</a>, PhD candidate, Department of Human Nutrition, <a href="https://theconversation.com/institutions/university-of-otago-1304">University of Otago</a> and <a href="https://theconversation.com/profiles/meredith-peddie-1548807">Meredith Peddie</a>, Senior Lecturer, Department of Human Nutrition, <a href="https://theconversation.com/institutions/university-of-otago-1304">University of Otago</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How do I keep my fruit, veggies and herbs fresh longer? Are there any ‘hacks’?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/senaka-ranadheera-199225">Senaka Ranadheera</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> We all know <a href="https://theconversation.com/frozen-canned-or-fermented-when-you-cant-shop-often-for-fresh-vegetables-what-are-the-best-alternatives-131678">fresh produce is good for us</a>, but fruit, vegetables and herbs have a tendency to perish quickly if left uneaten. This is because <a href="https://www.sciencedirect.com/science/article/abs/pii/S2212429219305188">even after harvesting</a>, produce from living plants tends to continue its biological processes. This includes respiration: producing energy from stored carbohydrates, proteins and fats while releasing carbon dioxide and water vapour. (Ever found a sprouting potato in your pantry?) On top of that, fresh produce also <a href="https://www.mdpi.com/journal/agriculture/special_issues/quality_safety_fresh_produce">spoils easily thanks to various microbes</a> – both harmless and ones that can cause disease, called pathogens. Simply chucking things in the fridge won’t solve the problem, as different types of plants will react differently to how they’re stored. So, how can you combat food waste and keep produce fresh for longer? Fortunately, there are some helpful tips. <h2>Freshness and quality begin at the farm</h2> Farmers always aim to harvest produce when it’s at an optimal condition, but both pre-harvest and post-harvest factors will affect freshness and quality even before you buy it. Pre-harvest factors are agricultural, such as climatic conditions, soil type and water availability. <a href="https://www.sciencedirect.com/science/article/abs/pii/S2212429219305188">Post-harvest factors</a> include washing and cleaning after harvesting, transportation and distribution, processing and packaging, and storage. As consumers we can’t directly control these factors – sometimes the veggies we buy just won’t be as good. But we can look out for things that will affect the produce once we bring it home. One major thing to look out for is bruised, wounded or damaged produce. This can happen at any stage of post-harvest handling, and can really speed up the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0308814609001411">decay of your veggies and fruit</a>. Moisture loss through damaged skin speeds up deterioration and nutrient loss. The damage also makes it easier for <a href="https://www.sciencedirect.com/science/article/pii/S2468014119301943">spoilage microbes</a> to get in. <h2>To wash or not to wash?</h2> You don’t need to wash your produce before storing it. A lot of what we buy has already been washed commercially. In fact, if you wash your produce and can’t get it completely dry, the added moisture could speed up decay in the fridge. But washing produce <a href="https://theconversation.com/do-we-really-have-to-wash-fruit-and-vegetables-53039">just before you use it</a> is important to remove dirt and pathogenic bugs. Don’t use vinegar in your washing water despite what you see on social media. Studies indicate <a href="https://pubmed.ncbi.nlm.nih.gov/16496573/">vinegar has no effect</a> on lowering microbial loads on fresh produce. Similarly, don’t use baking soda. Even though there’s some evidence baking soda <a href="https://pubs.acs.org/doi/10.1021/acs.jafc.7b03118">can remove pesticide residues</a> from the surface of some produce, it’s not advisable at home. Just use plain tap water. <h2>Location, location, location</h2> The main thing you need is the correct type of packaging and the correct location – you want to manage moisture loss, decay and ripening. The three main storage options are on the counter, in the fridge, or in a “cool, dry and dark place”, such as the pantry. Here are some common examples of produce and where best to put them. Bananas, onion, garlic, potatoes, sweet potato and whole pumpkin will do better in a dark pantry or cupboard. Don’t store potatoes and onions together: onions produce a gas called ethylene that makes potatoes spoil quicker, while the high moisture in potatoes spoils onions. In fact, don’t store fruits such as apples, pears, avocado and bananas together, because these fruits <a href="https://www.tandfonline.com/doi/full/10.1080/15538362.2013.748378#:%7E:text=%27Malindi%27%20had%20higher%20respiration%20rates,retention%20in%20fruit%20during%20ripening">release ethylene gas</a> as they ripen, making nearby fruits ripen (and potentially spoil) much faster. That is, unless you do want to ripen your fruits fast. All leafy greens, carrots, cucumbers, cauliflower and broccoli will do best in the low-humidity drawer (crisper) in the fridge. You can put them in perforated plastic bags to retain moisture but maintain air flow. But don’t put them in completely sealed bags because this can slow down ripening while <a href="https://ucanr.edu/sites/hdnmastergardeners/files/338860.pdf">trapping carbon dioxide</a>, leading to decay and bad smells. Some fruits will also do best in the fridge. For example, apples and citrus fruits such as oranges can keep fresh longer in the fridge (crisper drawer), although they can stay at room temperature for short periods. However, don’t store watermelon in the fridge for too long, as it will lose its flavour and deep red colour if kept refrigerated <a href="https://ucanr.edu/sites/hdnmastergardeners/files/338860.pdf">for longer than three days</a>. Most herbs and some leafy vegetables – like celery, spring onions and asparagus – can be kept with stems in water to keep them crisp. Keep them in a well-ventilated area and away from direct sunlight, so they don’t get too warm and wilt. <figure><iframe src="https://www.youtube.com/embed/cHu10C1DAds?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Experimenting at home is a good way to find the best ways to store your produce.</figcaption></figure> <h2>Fight food waste and experiment</h2> Don’t buy too much. Whenever possible, buy only small amounts so that you don’t need to worry about keeping them fresh. Never buy bruised, wounded or damaged produce if you plan to keep it around for more than a day. “Process” your veggies for storage. If you do buy a large quantity – maybe a bulk option was on sale – consider turning the produce into something you can keep for longer. For example, banana puree made from really ripe bananas can be <a href="https://www.sciencedirect.com/science/article/abs/pii/S0023643817300853">stored for up to 14 days at 4°C</a>. You can use <a href="https://theconversation.com/frozen-canned-or-fermented-when-you-cant-shop-often-for-fresh-vegetables-what-are-the-best-alternatives-131678">freezing, blanching, fermentation and canning</a> for most vegetables. Consider vacuum sealing. Vacuum packaging of vegetables and berries can keep them fresh longer, as well. For example, vacuum-sealed beans can keep up to 16 months in the fridge, but will last only about <a href="https://www.vacpac.com.au/vacuum-sealed-life-expectancy-how-long-will-my-vacuum-sealed-products-last">four weeks in the fridge unsealed</a>. Keep track. Arrange your fridge so you can see the produce easily and use it all before it loses freshness. Experiment with storage hacks. Social media is full of tips and hacks on how best to store produce. Turn your kitchen into a lab and try out any tips you’re curious about – they might just work. You can even use these experiments as a way to teach your kids about the importance of reducing food waste. Grow some of your own. This isn’t <a href="https://theconversation.com/growing-your-own-food-and-foraging-can-help-tackle-your-ballooning-grocery-bill-heres-how-216264">feasible for all of us</a>, but you can always try having some herbs in pots so you don’t need to worry about keeping them fresh or using up a giant bunch of mint all at once. <a href="https://theconversation.com/health-check-are-microgreens-better-for-you-than-regular-greens-73950">Growing your own microgreens</a> could be handy, too.<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/226763/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/senaka-ranadheera-199225">Senaka Ranadheera</a>, Associate Professor, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do optimists really live longer? Here’s what the research says

<a href="https://theconversation.com/profiles/fuschia-sirois-331254">Fuschia Sirois</a>, <a href="https://theconversation.com/institutions/durham-university-867">Durham University</a> Do you tend to see the glass as half full, rather than half empty? Are you always looking on the bright side of life? If so, you may be surprised to learn that this tendency could actually be good for your health. A <a href="https://content.apa.org/record/2020-71981-001">number of studies</a> have shown that optimists enjoy higher levels of wellbeing, better sleep, lower stress and even better cardiovascular health and immune function. And now, <a href="https://pubmed.ncbi.nlm.nih.gov/35674052/">a recent study</a> has shown that being an optimist is linked to longer life. To conduct their study, researchers tracked the lifespan of nearly 160,000 women aged between 50 to 79 for a period of 26 years. At the beginning of the study, the women completed a <a href="https://local.psy.miami.edu/people/faculty/ccarver/availbale-self-report-instruments/lot-r/">self-report measure of optimism</a>. Women with the highest scores on the measure were categorised as optimists. Those with the lowest scores were considered pessimists. Then, in 2019, the researchers followed up with the participants who were still living. They also looked at the lifespan of participants who had died. What they found was that those who had the highest levels of optimism were more likely to live longer. More importantly, the optimists were also more likely than those who were pessimists to live into their nineties. Researchers refer to this as “exceptional longevity”, considering the average lifespan for women is about 83 years in developed countries. What makes these findings especially impressive is that the results remained even after accounting for other factors known to predict a long life – including education level and economic status, ethnicity, and whether a person suffered from depression or other chronic health conditions. But given this study only looked at women, it’s uncertain whether the same would be true for men. However, <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1900712116">another study</a> which looked at both men and women also found that people with the highest levels of optimism enjoyed a lifespan that was between 11% and 15% longer than those who were the least optimistic. <h2>The fountain of youth?</h2> So why is it that optimists live longer? At first glance it would seem that it may have to do with their healthier lifestyle. For example, <a href="https://www.ahajournals.org/doi/10.1161/CIRCRESAHA.117.310828">research from several studies</a> has found that optimism is linked to eating a healthy diet, staying physically active, and being less likely to smoke cigarettes. These healthy behaviours are well known to improve heart health and <a href="https://www.who.int/news-room/fact-sheets/detail/noncommunicable-diseases">reduce the risk</a> for cardiovascular disease, which is a <a href="https://www.who.int/news-room/fact-sheets/detail/cardiovascular-diseases-(cvds)">leading cause of death</a> globally. Adopting a healthy lifestyle is also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3857242/">important for reducing the risk</a> of other potentially deadly diseases, such as diabetes and cancer. But having a healthy lifestyle may only be part of the reason optimists live a longer than average life. This latest study found that lifestyle only accounted for 24% of the link between optimism and longevity. This suggests a number of other factors affect longevity for optimists. Another possible reason could be due to the way optimists manage stress. When faced with a stressful situation, optimists tend to deal with it head-on. They <a href="https://pubmed.ncbi.nlm.nih.gov/16859439/">use adaptive coping strategies</a> that help them resolve the source of the stress, or view the situation in a less stressful way. For example, optimists will problem-solve and plan ways to deal with the stressor, call on others for support, or try to find a “silver lining” in the stressful situation. All of these approaches are well-known to reduce feelings of stress, as well as the biological reactions that occur when we feel stressed. It’s these <a href="https://www.apa.org/topics/stress/body">biological reactions to stress</a> –- such as elevated cortisol (sometimes called the “stress hormone”), increased heart rate and blood pressure, and impaired immune system functioning –- that can take a toll on health over time and increase the risk for developing <a href="https://www.sciencedirect.com/science/article/pii/S0889159115004316?via%3Dihub">life-threatening diseases</a>, such as cardiovascular disease. In short, the way optimists cope with stress may help protect them somewhat against its harmful effects. <h2>Looking on the bright side</h2> Optimism is typically viewed by researchers as a relatively stable personality trait that is determined by both <a href="https://www.cambridge.org/core/journals/twin-research-and-human-genetics/article/sex-differences-in-the-genetic-architecture-of-optimism-and-health-and-their-interrelation-a-study-of-australian-and-swedish-twins/58F21AA11943D44B4BA4C63A966E6AC7">genetic</a> and early childhood influences (such as having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6541423/">secure and warm relationship</a> with your parents or caregivers). But if you’re not naturally prone to seeing the glass as half full, there are some ways you can increase your <a href="https://www.tandfonline.com/doi/abs/10.1080/17439760.2016.1221122?journalCode=rpos20">capacity to be optimistic</a>. Research shows optimism can change over time, and can be cultivated by engaging in simple exercises. For example, visualising and then writing about your “<a href="https://www.psychologytoday.com/us/blog/what-matters-most/201303/what-is-your-best-possible-self">best possible self</a>” (a future version of yourself who has accomplished your goals) is a technique that studies have found can <a href="https://www.tandfonline.com/doi/full/10.1080/17439760.2016.1221122">significantly increase optimism</a>, at least temporarily. But for best results, the goals need to be both positive and reasonable, rather than just wishful thinking. Similarly, simply <a href="https://www.tandfonline.com/doi/abs/10.3200/SOCP.149.3.349-364">thinking about positive future events</a> can also be effective for boosting optimism. It’s also crucial to temper any expectations for success with an accurate view of what you can and can’t control. Optimism is reinforced when we experience the positive outcomes that we expect, and <a href="https://psycnet.apa.org/record/1970-20680-001">can decrease</a> when these outcomes aren’t as we want them to be. Although more research is needed, it’s possible that regularly envisioning yourself as having the best possible outcomes, and taking realistic steps towards achieving them, can help develop an optimistic mindset. Of course, this might be easier said than done for some. If you’re someone who isn’t naturally optimistic, the best chances to improve your longevity is by <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1003332">living a healthy lifestyle</a> by staying physically active, eating a healthy diet, managing stress, and getting a good night’s sleep. Add to this cultivating a more optimistic mindset and you might further increase your chances for a long life.<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/184785/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/fuschia-sirois-331254">Fuschia Sirois</a>, Professor in Social & Health Psychology, <a href="https://theconversation.com/institutions/durham-university-867">Durham University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

People in the world’s ‘blue zones’ live longer – their diet could hold the key to why

<a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Ageing is an inevitable part of life, which may explain our <a href="https://time.com/4672969/why-do-people-want-to-live-so-long/">strong fascination</a> with the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2726954">quest for longevity</a>. The allure of <a href="https://pubmed.ncbi.nlm.nih.gov/26566891/">eternal youth</a> drives a <a href="https://www.alliedmarketresearch.com/longevity-and-anti-senescence-therapy-market-A14010">multi-billion pound industry</a> ranging from anti-ageing products, supplements and <a href="https://www.everydayhealth.com/diet-nutrition/longevity-diet">diets</a> for those hoping to extend their lifespan. f you look back to the turn of the 20th century, average life expectancy in the UK was around 46 years. Today, it’s closer to <a href="https://population.un.org/wpp/">82 years</a>. We are in fact <a href="https://pubmed.ncbi.nlm.nih.gov/27706136/">living longer than ever before</a>, possibly due to medical advancements and improved <a href="https://www.health.org.uk/publications/reports/mortality-and-life-expectancy-trends-in-the-uk">living and working conditions</a>. But living longer has also come at a price. We’re now seeing higher rates of <a href="https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/ghe-leading-causes-of-death">chronic and degenerative diseases</a> – with heart disease consistently topping the list. So while we’re fascinated by what may help us live longer, maybe we should be more interested in being healthier for longer. Improving our “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4632858/">healthy life expectancy</a>” remains a global challenge. Interestingly, certain locations around the world have been discovered where there are a high proportion of centenarians who display remarkable physical and mental health. The <a href="https://pubmed.ncbi.nlm.nih.gov/15489066/">AKEA study of Sardinia, Italy</a>, as example, identified a “blue zone” (named because it was marked with blue pen), where there was a higher number of locals living in the central-eastern mountainous areas who had reached their 100th birthday compared with the wider Sardinian community. This longevity hotspot has since been expanded, and now includes several other areas around the world which also have greater numbers of longer-living, healthy people. Alongside Sardinia, these blue zones are now <a href="https://www.netflix.com/gb/title/81214929">popularly recognised</a> as: Ikaria, Greece; Okinawa, Japan; Nicoya, Costa Rica; and Loma Linda, California. Other than their long lifespans, people living in these zones also appear to share certain other commonalities, which centre around being <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3874460">part of a community</a>, having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224996/">life purpose</a>, eating <a href="https://pubmed.ncbi.nlm.nih.gov/33514872/">nutritious, healthy foods</a>, keeping <a href="https://www.nature.com/articles/s41398-021-01735-7">stress levels</a> low and undertaking purposeful daily <a href="https://pubmed.ncbi.nlm.nih.gov/30202288/">exercise or physical tasks</a>. Their longevity could also relate to their <a href="https://pubmed.ncbi.nlm.nih.gov/9010380/">environment</a>, being mostly rural (or less polluted), or because of <a href="https://pubmed.ncbi.nlm.nih.gov/22253498/">specific longevity genes</a>. However, studies indicate genetics may only account for <a href="https://pubmed.ncbi.nlm.nih.gov/8786073">around 20-25% of longevity</a> – meaning a person’s lifespan is a complex interaction between lifestyle and genetic factors, which contribute to a long and healthy life. <h2>Is the secret in our diet?</h2> When it comes to diet, each blue zone has its own approach – so one specific food or nutrient does not explain the remarkable longevity observed. But interestingly, a diet rich in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662288">plant foods</a> (such as locally-grown vegetables, fruits and legumes) does appear to be reasonably consistent across these zones. For instance, the Seventh-day Adventists of Loma Linda are <a href="https://pubmed.ncbi.nlm.nih.gov/10641813/">predominately vegetarian</a>. For centenarians in Okinawa, <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">high intakes of flavonoids</a> (a chemical compound typically found in plants) from purple sweet potatoes, soy and vegetables, have been linked with <a href="https://pubmed.ncbi.nlm.nih.gov/11710359/">better cardiovascular health</a> – including lower cholesterol levels and lower incidences of stroke and heart disease. In Nicoya, consumption of locally produced rice and beans has been associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34444746/">longer telomere length</a>. Telomeres are the structural part at the end of our chromosomes which protect our genetic material. Our telomeres get shorter each time a cell divides – so get progressively shorter as we age. Certain <a href="https://pubmed.ncbi.nlm.nih.gov/21102320/">lifestyle factors</a> (such as smoking and poor diet) can also shorten telomere length. It’s thought that telomere length acts as a <a href="https://pubmed.ncbi.nlm.nih.gov/31728493/">biomarker of ageing</a> – so having longer telomeres could, in part, be linked with longevity. But a plant-based diet isn’t the only secret. In Sardinia, for example, meat and fish is consumed in moderation in addition to locally grown vegetables and <a href="https://journalofethnicfoods.biomedcentral.com/articles/10.1186/s42779-022-00152-5">traditional foods</a> such as acorn breads, pane carasau (a sourdough flatbread), honey and soft cheeses. Also observed in several blue zone areas is the inclusion of <a href="https://www.jacc.org/doi/10.1016/j.jacc.2021.10.041">olive oil</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/33669360/">wine</a> (in moderation – around 1-2 glasses a day), as well as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830687/">tea</a>. All of these contain powerful antioxidants which may help <a href="https://ncbi.nlm.nih.gov/pmc/articles/PMC10049696/">protect our cells</a> from damage <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6273542/">as we age</a>. Perhaps then, it’s a combination of the protective effects of various nutrients in the diets of these centenarians, which explains their exceptional longevity. Another striking observation from these longevity hot spots is that meals are typically <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7232892">freshly prepared at home</a>. Traditional blue zone diets also don’t appear to contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6538973/">ultra-processed foods</a>, fast foods or sugary drinks which may <a href="https://pubmed.ncbi.nlm.nih.gov/32330232/">accelerate ageing</a>. So maybe it’s just as important to consider what these longer-living populations are not doing, as much as what they are doing. There also appears to be a pattern of eating until 80% full (in other words partial <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9036399/">caloric reduction</a>. This could be important in also supporting how our cells deal with damage as we age, which could mean a longer life. Many of the factors making up these blue zone diets – primarily plant-based and natural whole foods – are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/35706591/">lower risk of chronic diseases</a> such as <a href="https://pubmed.ncbi.nlm.nih.gov/28728684/">heart disease</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/37589638/">cancer</a>. Not only could such diets contribute to a <a href="https://pubmed.ncbi.nlm.nih.gov/37836577/">longer, healthier life</a>, but could support a more <a href="https://pubmed.ncbi.nlm.nih.gov/33397404/">diverse gut microbiome</a>, which is also associated with healthy ageing. Perhaps then we can learn something from these remarkable centenarians. While diet is only one part of the bigger picture when it comes to longevity, it’s an area we can do something about. In fact, it might just be at the heart of improving not only the quality of our health, but the quality of how we age.<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/221463/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, Professor of Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, PhD Candidate in Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, Senior Lecturer in Public Health and Nutrition, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What happens if King Charles can no longer perform his duties?

<a href="https://theconversation.com/profiles/anne-twomey-6072">Anne Twomey</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> King Charles III’s <a href="https://www.abc.net.au/news/2024-02-06/king-charles-cancer-diagnosis-revealed-by-buckingham-palace/103430320">cancer diagnosis</a> will turn minds to the question of what happens if he becomes unable to fulfil his constitutional duties. Buckingham Palace has announced he will continue performing his official paperwork and his weekly meetings with the prime minister throughout his treatment. But what happens if he becomes seriously ill? There are three options: counsellors of state, regency and abdication. <h2>Counsellors of state</h2> First, King Charles can delegate some or most of his royal functions to <a href="https://www.legislation.gov.uk/ukpga/Edw8and1Geo6/1/16/section/6">counsellors of state</a>, as happens most commonly when he is travelling overseas. Two counsellors of state act jointly in exercising royal powers such as assenting to laws, receiving ambassadors and holding <a href="https://commonslibrary.parliament.uk/research-briefings/cbp-7460/">Privy Council</a> meetings. The <a href="https://www.royal.uk/counsellors-of-state">counsellors of state</a> are the spouse of the sovereign and the next four adults in line of succession to the throne – being Queen Camilla, Prince William, Prince Harry, Prince Andrew and Princess Beatrice. However, Prince Harry is excluded while he is outside the United Kingdom, and in practice Prince Andrew and Princess Beatrice are not called on to act as they are not “working royals”. As this left only Queen Camilla and Prince William to perform the role, a <a href="https://www.legislation.gov.uk/ukpga/2022/47/2022-12-07/data.html#:%7E:text=An%20Act%20to%20add%20His,delegated%20as%20Counsellors%20of%20State.">law</a> was passed in the UK in 2022 to <a href="https://commonslibrary.parliament.uk/creating-more-counsellors-of-state/">add Princess Anne and Prince Edward</a> to the list. Counsellors of state may carry out most of the sovereign’s functions while he is ill, but they cannot dissolve parliament, except on his instruction, and they cannot create peers. Whether they can appoint a prime minister remains a matter of debate. Most significantly, they cannot exercise powers with respect to the King’s other realms, such as Australia. <h2>Regency</h2> The second option is a regency. This occurs if the King “is by reason of infirmity of mind or body <a href="https://www.legislation.gov.uk/ukpga/Edw8and1Geo6/1/16/section/2">incapable</a> for the time being of performing the royal functions”. The sovereign does not control when or for how long a regency occurs. Instead, it is initiated by a declaration of three or more of: the sovereign’s spouse, the lord chancellor, the speaker of the House of Commons, the lord chief justice of England and the <a href="https://www.judiciary.uk/about-the-judiciary/who-are-the-judiciary/judges/profile-mor/">master of the rolls</a>. The UK’s Regency Act <a href="https://www.legislation.gov.uk/ukpga/Edw8and1Geo6/1/16/section/3">requires</a> Prince William to be regent, as he is the next adult in line of succession to the crown. The regent has the powers of the King with respect to the United Kingdom, but cannot change the order of succession to the crown. The Regency Act does not give the regent powers in relation to realms such as Australia and New Zealand. New Zealand resolved the problem by inserting a <a href="https://www.legislation.govt.nz/act/public/1986/0114/latest/DLM94216.html">section</a> into its Constitution Act which provides that whoever is made regent under the law of the UK may perform the royal functions of the sovereign with respect to New Zealand. Australia, however, has done nothing in this regard, so a British regent would have no powers with respect to Australia. <h2>Abdication</h2> The final option for an incapacitated monarch is abdication. This leads to difficult questions about how an abdication would operate in relation to each of the realms. When King Edward VIII abdicated in 1936, it was achieved by both a signed <a href="https://www.nationalarchives.gov.uk/education/resources/significant-events/abdication-of-edward-viii-1936/">instrument of abdication</a> and the enactment of <a href="https://www.legislation.gov.uk/ukpga/Edw8and1Geo6/1/3/enacted#:%7E:text=(1)Immediately%20upon%20the%20Royal,and%20there%20shall%20be%20a">legislation</a> to which the various realms, including Australia, assented. This is not possible today, as the UK can <a href="https://www6.austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/num_act/aa1986114/s1.html">no longer legislate</a> with respect to Australia. Abdication would therefore raise difficult questions about whether there needed to be a separate abdication of the King of Australia, to trigger the application of the rules of succession that are now part of Australian law, or whether <a href="http://www.austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/consol_act/coaca430/s2.html">covering clause 2</a> of the Constitution, which defines the sovereign by reference to Queen Victoria’s “heirs and successors in the sovereignty of the United Kingdom”, would apply. Because of the potential constitutional messiness of dealing with the King’s role in his 14 realms beyond the United Kingdom, it is likely abdication would be avoided. <h2>Consequences for Australia</h2> If King Charles were incapacitated and counsellors of state or a regent were appointed, would this cause any real problem in Australia? The King’s only remaining substantial powers with respect to Australia are the appointment and removal of the governor-general and the state governors. The governor-general’s term is expected to expire in the middle of the year. If King Charles were then seriously ill and unable to appoint a new governor-general, no one could do so, as neither counsellors of state nor a regent could do so. Instead, the current governor-general, David Hurley, could choose to continue in office, as there is no formal termination of his office until he is replaced. Alternatively, he could resign and his office could be filled on a temporary basis by a state governor as <a href="http://www.austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/consol_act/coaca430/xx4.html">administrator</a>, as is the usual practice when there is a vacancy in the office. If the office of a state governor becomes vacant, the <a href="https://www.governor.nsw.gov.au/governor/lieutenant-governor/role-of-the-lieutenant-governor/">lieutenant-governor</a>, who is often the chief justice of the state, can exercise the governor’s functions. However, if a regency were to continue for a long time – perhaps years – this could become unsustainable. The other consideration is that if there is a regency, there is no power to <a href="https://www.theaustralian.com.au/national-affairs/opinion/in-race-to-palace-governor-general-has-inside-running/news-story/d3918f42af1d081f203daa65f5b53e0f">dismiss a governor-general</a>. So if a constitutional crisis arose, such as that in 1975 with the dismissal of the Whitlam government, the governor-general would know that he or she could act without the prospect of dismissal on the advice of the prime minister. This unbalances the constitutional pressures that are deliberately built into the system, giving a stronger hand to the governor-general and weakening the position of the prime minister. The <a href="https://michaelwest.com.au/king-charles-illness-affects-australia/">problem</a> could be addressed in the same way as the rules of succession to the throne were changed <a href="https://www.legislation.gov.au/C2015A00023/asmade/text">in 2015</a> to remove gender discrimination. It would involve each state enacting a law requesting the Commonwealth to enact a law that recognised the authority of a regent to exercise the sovereign’s powers with respect to Australia. While it is not essential to fix this problem, it would still be wise, as a matter of orderly constitutional housekeeping, to address it before any real difficulties arise.<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/222870/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/anne-twomey-6072">Anne Twomey</a>, Professor emerita, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

You can’t reverse the ageing process but these 5 things can help you live longer

<a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> At this time of year many of us resolve to prioritise our health. So it is no surprise there’s a <a href="https://digiday.com/marketing/health-food-brands-ramp-up-marketing-efforts-around-consumers-new-years-resolutions/">roaring trade</a> of products purporting to guarantee you live longer, be healthier and look more youthful. While an <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4822264/">estimated</a> 25% of longevity is determined by our genes, the rest is determined by what we do, day to day. There are no quick fixes or short cuts to living longer and healthier lives, but the science is clear on the key principles. Here are five things you can do to extend your lifespan and improve your health. <h2>1. Eat a predominantly plant-based diet</h2> What you eat has a huge impact on your health. The evidence overwhelmingly <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8210981/#:%7E:text=According%20to%20an%20expansive%20review,13%20Given%20that%20so%20many">shows</a> eating a diet high in plant-based foods is associated with health and longevity. If you eat more plant-based foods and less meat, processed foods, sugar and salt, you reduce your risk of a range of illnesses that shorten our lives, including heart disease and cancer. Plant-based foods <a href="https://www.nature.com/articles/s41398-019-0552-0">are rich</a> in nutrients, phytochemicals, antioxidants and fibre. They’re also anti-inflammatory. All of this protects against damage to our cells as we age, which helps prevent disease. No particular diet is right for everyone but one of the most studied and <a href="https://www.hsph.harvard.edu/nutritionsource/healthy-weight/diet-reviews/mediterranean-diet/#:%7E:text=%5B6%5D%20Those%20who%20had%20the,who%20had%20the%20lowest%20adherence.">healthiest</a> is the <a href="https://www.eatingwell.com/article/291120/mediterranean-diet-for-beginners-everything-you-need-to-get-started/">Mediterranean diet</a>. It’s based on the eating patterns of people who live in countries around the Mediterranean Sea and emphases vegetables, fruits, wholegrains, legumes, nuts and seeds, fish and seafood, and olive oil. <h2>2. Aim for a healthy weight</h2> Another important way you can be healthier is to try and achieve a healthy weight, as obesity <a href="https://www.healthline.com/health/obesity/how-obesity-affects-body">increases the risk</a> of a number of health problems that shorten our lives. Obesity puts strain on all of our body systems and has a whole myriad of physiological effects including causing inflammation and hormonal disturbances. These <a href="https://www.ncbi.nlm.nih.gov/books/NBK572076/">increase your chances</a> of a number of diseases, including heart disease, stroke, high blood pressure, diabetes and a number of cancers. In addition to affecting us physically, obesity is also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6052856/">associated with</a> poorer psychological health. It’s linked to depression, low self-esteem and stress. One of the biggest challenges we face in the developed world is that we live in an <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6817492/">environment</a> that promotes obesity. The ubiquitous marketing and the easy availability of high-calorie foods our bodies are hard-wired to crave mean it’s easy to consume too many calories. <h2>3. Exercise regularly</h2> We all know that exercise is good for us – the <a href="https://www.insurancebusinessmag.com/au/news/breaking-news/hcf-reveals-australias-most-popular-new-years-resolutions-for-2023-431665.aspx">most common resolution</a> we make this time of year is to do more exercise and to get fitter. Regular exercise <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">protects</a> against chronic illness, lowers your stress and improves your mental health. While one of the ways exercising helps you is by supporting you to control your weight and lowering your body fat levels, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1402378/#:%7E:text=For%20instance%2C%20routine%20physical%20activity,HDL%5D%20cholesterol%20levels%20and%20decreased">effects</a> are broader and include improving your glucose (blood sugar) use, lowering your blood pressure, reducing inflammation and improving blood flow and heart function. While it’s easy to get caught up in all of the hype about different exercise strategies, the evidence <a href="https://www.medicalnewstoday.com/articles/320760">suggests</a> that any way you can include physical activity in your day has health benefits. You don’t have to run marathons or go to the gym for hours every day. Build movement into your day in any way that you can and do things that you enjoy. <h2>4. Don’t smoke</h2> If you want to be healthier and live longer then don’t smoke or vape. Smoking cigarettes affects almost every organ in the body and is associated with both a shorter and lower quality of life. There is no safe level of smoking – every cigarette increases your <a href="https://theconthatkills.org.au/?utm_source=googlesearch&utm_medium=search&utm_campaign=theconthatkills23&utm_content=RSA&gclid=Cj0KCQjwqP2pBhDMARIsAJQ0Czrlep6EQHC-8_9xUhpz0h9v2ZglMF-6-k7_65awq8FxVaIL5HRoivwaAqJwEALw_wcB&gclsrc=aw.ds">chances of developing</a> a range of cancers, heart disease and diabetes. Even if you have been smoking for years, by giving up smoking at any age you can experience <a href="https://www.cdc.gov/tobacco/quit_smoking/how_to_quit/benefits/index.htm">health benefits</a> almost immediately, and you can reverse many of the harmful effects of smoking. If you’re thinking of switching to vapes as a healthy long term option, <a href="https://theconversation.com/can-vaping-help-people-quit-smoking-its-unlikely-204812">think again</a>. The long term health effects of vaping are not fully understood and they come with their own <a href="https://theconversation.com/no-vapes-arent-95-less-harmful-than-cigarettes-heres-how-this-decade-old-myth-took-off-203039">health risks</a>. <h2>5. Prioritise social connection</h2> When we talk about living healthier and longer, we tend to focus on what we do to our physical bodies. But one of the most important discoveries over the past decade has been the recognition of the importance of spiritual and psychological health. People who are lonely and socially isolated have a much higher risk of dying early and are <a href="https://healthnews.com/longevity/healthspan/social-connection-and-longevity/#:%7E:text=One%20of%20the%20biggest%20benefits,the%20following%20factors%20and%20influences.">more likely</a> to suffer from heart disease, stroke, dementia as well as anxiety and depression. Although we don’t fully understand the mechanisms, it’s likely due to both behavioural and biological factors. While people who are more socially connected are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3150158/">more likely</a> to engage in healthy behaviours, there also seems to be a more direct physiological effect of loneliness on the body. So if you want to be healthier and live longer, build and maintain your connections to others.<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/214580/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, Associate Professor, Epidemiology, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

7 hacks for retirees to make your money last longer

As Australians continue to live longer, the squeeze is on to make each dollar last longer – and never moreso than in retirement. <a href="https://www.aihw.gov.au/reports/life-expectancy-deaths/deaths-in-australia/contents/life-expectancy">Life expectancies in Australia</a> are now 85.4 years for women and 81.3 years for men. Meanwhile, the <a href="https://www.abs.gov.au/statistics/labour/employment-and-unemployment/retirement-and-retirement-intentions-australia/latest-release">average age at retirement</a> for all retirees is 56.3 years. That’s up to 29.1 years of retirement to be paid for without a salaried income. Thankfully, making money last longer is just possible, with the help of a few tips and tricks. <ol> <li>Embrace seniors’ discounts</li> </ol> It was once said that “it’s better to pay full price than to admit you’re a senior citizen”. Really? Who wouldn’t prefer the extra cash! Being “senior” opens the door to numerous discounts and freebies. If you haven’t already, apply for your eligible concession cards, including the <a href="https://www.servicesaustralia.gov.au/commonwealth-seniors-health-card">Commonwealth Seniors Health Card</a> (for discounted healthcare and prescriptions) and state or territory seniors card (for discounted/free vehicle registration, public transport and other services). Additionally, many businesses offer seniors discounts – insurers, retailers, attractions and more. But they may not advertise these discounts widely, so it pays to ask. <ol start="2"> <li>Maintain a plan</li> </ol> Having a plan and keeping it up to date ensures you don’t overdraw from super, losing the income-generating power of those funds and running out prematurely. I prefer a ‘savings and investment plan’, which sounds nicer and is more comprehensive than a ‘budget’. Incorporate your goals, expenses, assets, and incomes – visibility keeps you disciplined and allows you to act quickly if something is amiss. <ol start="3"> <li>Spend points</li> </ol> Many retirees have held their current credit card, store cards and frequent flyer account for years – decades even. How many points are sitting there unused? These points generally aren’t transferable, so can’t be gifted in your will. It’s use them or lose them! Points can pay for everything from groceries to homewares, travel and even your Christmas shopping – conserving your cash and super. <ol start="4"> <li>Get comfortable</li> </ol> Rightsizing your home sooner rather than later has numerous benefits, such as: <ul> <li><a href="https://www.ato.gov.au/Individuals/Super/Growing-and-keeping-track-of-your-super/How-to-save-more-in-your-super/Downsizer-super-contributions/">downsizer super contributions tax breaks</a> to boost superannuation earnings.</li> <li>paying less for your new home, since property prices generally track upwards whilst investing the extra equity.</li> <li>avoiding complications of moving later in life when your health or mobility may not be as good.</li> <li>avoiding a mistake - using the time to find exactly what you want, where you want, rather than being under pressure and having to spend stamp duty again</li> </ul> Home ownership is also a major determinant of how comfortable your retirement will be. And given the current state of Australia’s rental market, selling your home to move into rented accommodation could prove costly. <ol start="5"> <li>Retain protections</li> </ol> Protections are typically a cost – insurance premiums, legal fees, memberships etc. However, the cost of not having them in place can be far higher. Plus, in the case of insurances, prices and restrictions increase with age – meaning you pay more but get less value for that spend, compared with the more favourable terms of a long-held policy. By all means adjust your protections to suit your current and future needs. But think twice before trying to save a few dollars by discarding insurances or cancelling sports and social memberships that keep you active. <ol start="6"> <li>Update estate planning</li> </ol> Considerable costs (and heartache) inevitably hit a grieving partner and family where someone dies without having their affairs properly in order: <ul> <li>funeral costs and medical bills pile up if funds haven’t been allocated for them.</li> <li>delayed payouts from insurances and super if those details aren’t readily available. </li> <li>loss of economies of scale (living costs per person are cheaper for couples than singles). </li> <li>unexpected taxes, debts, and liabilities.</li> <li>legal conflicts arise where wills are unclear or outdated.</li> <li>a person’s wishes may go overlooked or be challenged where guardianships and power of attorney were not devised.</li> </ul> In extreme cases, the surviving spouse may be forced to sell their home to pay associated costs or because they can’t afford to maintain it alone. <ol start="7"> <li>Seek good advice</li> </ol> Just like a good doctor helps you stay physically and mentally healthy, a good financial adviser helps your finances stay healthy, tactically smart and use strategies to reduce tax which stretches your money further. Be sure their accreditation is up-to-date, and they have experience working with retirees (not just those planning for it during their working years). Often, the cost of this advice pales in comparison to the tax saved and additional income earned through benefits, structures and plans you never even knew about. What’s not to love about that! Helen Baker is a licensed Australian financial adviser and author of the new book, On Your Own Two Feet: The Essential Guide to Financial Independence for all Women (Ventura Press, $32.99).

6 ways to make your bananas last longer

Is there anything more delicious than fresh fruit? Fresh fruit is definitely up there, and it’s hard to beat the taste of a ripe banana. If you’re like us, you’re always trying to keep bananas fresh, especially if you’ve bought a bunch but only want to eat one at a time. Here are some of the most effective ways you can keep bananas from browning too quickly. Hang them Turns out there’s a scientific reason you should be hanging your bananas from a hook. Bananas start ripening as soon as they’re picked from trees – ethylene gas releases from the stems as soon as they’re picked, but when you hang bananas from a hook, the gas works more slowly. Hanging bananas also prevents them from bruising, which they’re more prone to do as they continue ripening. Buy a fruit basket with a built-in hook or a small under-cabinet hook made specifically for bananas. Either way, keep your bananas at room temperature while they ripen on the hook. Buy green bananas The easiest way to prolong your bananas’ shelf life is to buy the greenest bananas you can find. They’re picked while still green, then slowly ripen over time to reach that bright yellow we love. Instead of grabbing perfectly ripened bananas you’re eyeing, grab a green bunch you can hang from your hook and watch ripen. Wrap banana stems Remember that ethylene gas that makes bananas ripen? It comes from the stems, which means you can wrap those stems – with plastic or aluminium foil – to slow down the ripening process. For best results, take your bananas apart and wrap their stems individually. Place ripe bananas in the fridge One of the cardinal rules of banana storage is to never store them in the fridge. But rules are meant to be broken, especially when it comes to bananas. You should keep green bananas out of the fridge, but once your bananas have completely ripened, you can move them to the fridge where the cool temperatures will keep them from ripening further (for a few days at least). Freeze your bananas Freezing bananas is one of the easiest ways to keep them preserved for future use. But how you freeze bananas could have a big impact on how well they thaw. Freezing the entire bunch will darken the peels, and they’ll thaw poorly. Instead, consider freezing peeled, individual bananas or banana slices in resealable airtight bags. Buy a banana storage container Bruising can wreak havoc on your bananas. It leads to squishy parts and faster ripening, which is where hard cases built specifically for bananas come in handy. You can now buy reusable containers designed to hold one banana at a time, which are a great way to keep ripe bananas ready for lunch (or for your afternoon snack).

COVID is officially no longer a global health emergency – here’s what that means (and what we’ve learned along the way)

World Health Organisation (WHO) experts <a href="https://www.nytimes.com/2023/05/05/health/covid-who-emergency-end.html">have officially declared</a> that COVID <a href="https://www.who.int/news/item/05-05-2023-statement-on-the-fifteenth-meeting-of-the-international-health-regulations-(2005)-emergency-committee-regarding-the-coronavirus-disease-(covid-19)-pandemic">no longer constitutes</a> a public health emergency of international concern (Pheic). This coincides with the WHO’s new <a href="https://www.who.int/publications/i/item/WHO-WHE-SPP-2023.1">strategy</a> to transition from an emergency response to longer-term sustained COVID disease management. This may not change too much practically. COVID will still have pandemic status, and countries will continue to have their own authority as to whether to treat COVID as an emergency within their territories (some countries, <a href="https://www.npr.org/2023/04/11/1169191865/biden-ends-covid-national-emergency">including the US</a>, have already declared an end to the national emergency). For the global public health community, however, this is an event of monumental importance, drawing to a close the emergency response period which commenced on <a href="https://www.who.int/publications/m/item/covid-19-public-health-emergency-of-international-concern-(pheic)-global-research-and-innovation-forum">January 30 2020</a>. At the same time, for a large portion of the general public, it may well pass by relatively unnoticed. For many people, it’s been a long time since they viewed COVID as an emergency. In the UK for example, COVID no longer features in the regular Office for National Statistics <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/bulletins/publicopinionsandsocialtrendsgreatbritain/19aprilto1may2023">public opinion survey</a> that asks people what they think the key issues facing the country are. Even a year ago, <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/bulletins/publicopinionsandsocialtrendsgreatbritain/30marchto24april2022">only two in five Britons</a> were very or somewhat worried about COVID, according to the survey. Along with other behavioural scientists, I have been following <a href="https://www.swansea.ac.uk/research/research-highlights/health-innovation/public-during-pandemic/">public experiences of the pandemic</a> for the past three years. The results have yet to be peer reviewed but by summer 2022, many participants in <a href="https://psyarxiv.com/d6jcv">our research</a> described the pandemic as being like “a distant memory” or like it “never happened”. As we move into this next phase, it’s time to consider what we’ve learned about human behaviour during the pandemic, and what happens next. <h2>Old habits die hard</h2> In the early days of the pandemic, many behavioural scientists, myself included, wondered whether some of our pandemic habits <a href="https://theconversation.com/two-years-into-the-pandemic-which-of-our-newly-formed-habits-are-here-to-stay-178204">were here to stay</a>. Would <a href="https://www.itv.com/news/wales/2021-04-02/masks-to-stay-soldiering-on-through-the-common-cold-will-stop-and-the-nature-of-work-has-changed-forever-expert-says">face masks</a> become a regular wardrobe staple? Would people stop “soldiering on” and going into work when unwell? It turned out that for most people, the pandemic hasn’t permanently changed our behaviour and habits or created a “<a href="https://psyarxiv.com/d6jcv">new normal</a>”. Looking again at the UK, face mask use has consistently declined, with <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/datasets/publicopinionsandsocialtrendsgreatbritaincoronaviruscovid19andotherillnesses">figures from last month</a> suggesting that fewer than one in six adults had worn a face mask recently. Regular use is likely much less common. Social distancing has long since disappeared, except for a relatively small proportion of the public, in particular those most vulnerable to COVID. The COVID pandemic has taught us how adaptive behaviour can be, in particular how much people were willing to change their behaviour to keep themselves and others safe. Most people <a href="https://academic.oup.com/abm/article/56/8/781/6618645?login=false">followed the rules</a> during <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0258781">the height of the pandemic</a>, no matter how difficult. COVID has reminded us <a href="https://www.cambridge.org/core/services/aop-cambridge-core/content/view/759BE02FFE73E5C05EA429A3E1547D78/S2056467821000050a.pdf/resilience_in_the_age_of_covid19.pdf">how resilient we humans can be</a>. These pandemic adaptions, and the fact that our pre-pandemic behaviour bounced back so quickly, shows how important social cues and social norms are to behaviour. Putting on a mask or keeping our distance from others were habits – <a href="https://www.sciencedirect.com/science/article/abs/pii/S002210311100254X">actions triggered automatically</a> in response to contextual cues, such as seeing signs with pictures of people socially distancing. Social norms – what we think others are doing – were key to <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0277360">vaccine uptake</a> and to our uptake of <a href="https://www.nature.com/articles/s41562-020-0884-z">preventative measures in general</a>. As these contextual cues disappeared and the social norms started to change, and as vaccine coverage increased and the risk to the majority decreased, our behaviour changed. The pandemic has also demonstrated how important social connections and social, especially physical, contact can be. This is something <a href="https://theconversation.com/handshakes-and-hugs-are-good-for-you-its-vital-they-make-a-comeback-after-the-pandemic-158174">we have already argued</a> COVID couldn’t keep at bay forever. According to social safety theory, which sees stress and wellbeing as a product of biological, psychological and social factors, COVID <a href="https://www.sciencedirect.com/science/article/pii/S2352250X2200001X">posed a threat</a> to the “social fabric that makes humans resilient and keeps us alive and well”. It’s unsurprising that life satisfaction and happiness were <a href="https://bmjopen.bmj.com/content/10/7/e039334">lowest during lockdowns</a>, and <a href="https://www.covidsocialstudy.org/_files/ugd/064c8b_c525505ffa6b432f96dc41d6b6a985ea.pdf">recovered as people started to mix socially again</a>. <h2>The emergency isn’t over for everyone</h2> As we mark the end of the emergency phase it’s important to remember the <a href="https://covid19.who.int/">nearly seven million lives lost</a> due to COVID since 2020. And of course, we must consider that for some, especially those who are clinically vulnerable, the emergency is not yet over, and may never be. Although it’s no longer a Pheic, <a href="https://www.who.int/publications/i/item/WHO-WHE-SPP-2023.1">as the WHO reminds us</a>, COVID is still responsible for millions of infections and thousands of deaths each week around the world. Also, thanks to long COVID, hundreds of millions of people are in need of longer-term care.

The surprising habit that can help you live longer

Most of the time when we hear about life-extending wonders, it’s usually a bizarre new superfood or crazy exercise fad. But this is one we can get behind. <a href="http://bmjopen.bmj.com/content/6/2/e010164" target="_blank">A new study</a> from researchers at the University of Queensland have discovered that people who join social groups in retirement increase their quality and length of life. Researchers Dr Niklas Steffans and Dr Tegan Cruwys teamed up with UQ professors to track the health of 424 UK-based subjects over the age of 50 for six years and compare them to people of the same age, sex and health status who still worked. They found that the retirement group had a significantly higher quality of life, most notably if the retiree was a member of one or more social groups. “For retirees who belonged to two social groups before retirement, their chance of death was two per cent if they maintained the same number of groups for six years afterwards,” Dr Steffans told <a href="https://www.uq.edu.au/news/article/2016/02/want-longer-life-join-club" target="_blank">UQ News</a>. “For those who lost membership of one group, the risk of death rose to five percent, while those who lost membership of both groups had a 12 per cent chance of dying in the six years that followed.” Dr Steffans believes that a sense of belonging and identity helps retirees “sustain a meaningful and healthy life”. Also, many social group members were found to have higher levels of physical activity, which could account for a boost in longevity. “As people reach the end of their working lives, they are typically exposed to a lot of advice about how to plan their finances, medical care, and physical exercise in order to have a long and healthy retirement,” Dr Steffans told <a href="http://www.reuters.com/article/us-health-retirement-socializing-idUSKCN0VP2KL" target="_blank">Reuters</a>. “One important way for all of us to enhance the health of those who are retired is to support them in their efforts to be part of groups that provide them with a sense of communality and belonging.” Tell us in the comments below, are you a part of any social groups or clubs?

How to make your phone or tablet battery last longer

There’s nothing more frustrating than having your phone or tablet run out of battery when you need it most. Batteries of today seem to be draining at a more rapid pace… but rather than lugging your charger everywhere with you, here are a few easy ways you can help your device last the distance. Screen brightness The brighter your screen the more power it consumes. Lower the brightness levels slightly (your eyes will adjust) or change it to auto-brightness which will enable your phone to automatically adjust to the optimal level of brightness while conserving battery. GPS The GPS is a great feature in ensuring you’ll never get lost again. However, it also needs a substantial amount of battery power to function. It’s one of the biggest consumers of power so if you’re not using it switch it off. Wi-fi Keeping your wi-fi turned on at all time when not connected will quickly drain your battery. It’s because your phone is constantly trying to search for a wi-fi network to join so if you’re not using wi-fi switch it off. Just remember to turn it on again when you’re connected to a known wi-fi network like one at home otherwise it will eat up your data. Bluetooth Bluetooth is a convenient and useful feature in connection to other devices wirelessly but it also drains your power. Only switch it on when you know you’re using it. Apps We tend to have many apps running in the background that we’ve simply forgotten we opened up. But if apps are open they will be using battery power. Close the ones you’re not using. Turn it off It’s the most obvious solution and the most effective. If you know you’re not going to be using your phone for a few of hours (like when you’re watching a movie or going to bed) switching it off will stop any energy consumption. Image: Getty Images

6 tips to help your dog live longer

Our furry friends are more like family than just mates, and it pains us terribly when they age – sometimes ungracefully. Tim Norris, dog healer and founder of canine myofunctional therapy (canine massage), acupuncture and dog rehabilitation service <a href="http://bothendsofthelead.com.au/">Both Ends of The Lead</a>, walks us through how to care for an older dog to guarantee them a long and pain-free life. 1. Do not overfeed your dog This can lead to heart disease and joint problems. Feed your dog a nutritious diet to keep them at a healthy weight. These are two ways you can do a ‘self-check’ on your dog to see if they are not overweight. <ol> <li>Stand so that you have a view of your dog from above or over them. You should see there is an obvious waistline just behind their ribcage.</li> <li>If you are unsure, run your hands lightly down the side of your dog’s body and you should be able to feel their ribs.</li> </ol> If you are still not sure if you are overfeeding your dog after doing the checks, then you should speak to your vet and get their advice. There are many variables that determine how much to feed your dog. If you feed them a kibble diet, then the recommended amount to feed is usually stated on the packaging. If you have bought your food from your local vet, then they will normally recommend how much to feed specifically for your dog. We are now starting to see more people feeding a natural raw diet to their dog. If you do decide this suits your dog better, it’s recommended you seek out a certified animal nutritionist to guide you on how much to feed and also how to balance the meals appropriately for your dog specifically. As your dog ages and becomes less active (just like people), it’s likely you will need to feed them a little less, otherwise you risk a range of joint issues like arthritis through overfeeding. If you have a dog that appears underweight, then it is advisable to check with your vet to see if there are any conditions your dog may have that is stopping them from putting on weight. Most pet food brands have a senior range, which will usually include more omega 3, 6 and 9 for bones and joints. Try these ideas on <a href="http://www.readersdigest.com.au/pets/how-care-your-ageing-pet">how to care for an ageing pet</a>. 2. Don't exercise your dog too much or too little Many breeds of dogs are classed as a senior dog once they reach seven years of age, so it’s important to adapt the way you exercise them to minimise the impact on their joints and help them age more safely. High intensity chase games like throwing a ball can increase the risk of injury and joint problems like arthritis for senior dogs. The jumping, twisting and turning can put a great deal of excess strain on an older dog’s body and although many senior dogs will still enjoy chasing a ball, you should consider if this really is the most appropriate and safest way to exercise a senior dog. 3. If your dog is old, don't throw a ball too much If you do still throw a ball for your senior dog, it’s good to spend at least five minutes warming up their muscles first. This can help reduce the risk of an injury for them. You can do this by just letting them walk at their normal speed until they are warmed up and then throw the ball along the ground, so there is no jumping or twisting for them. If you ever see your dog uncomfortable or slowing down when chasing the ball, this is a good time to stop. If they are sore after chasing a ball or stiff the next day, then it would be wise to stop throwing the ball for them and find a different way to exercise them. 4. Make sure your home is safe If you have floor surfaces like floorboards, vinyl or tiles, these can be very slippery for an older dog, making it easy for them to fall and injure themselves. Placing non-slip surfaces down in areas that your dog uses heavily can help make the floors safer for your dog. 5. Use a step if your dog jumps on and off furniture If your senior dog likes to jump up on the couch or bed, think about having a halfway step so they can get up and down easier. This will help to reduce the impact on their joints and the injury risk. I have treated many dogs who have damaged muscles and ligaments jumping off a bed or couch. They are very avoidable injuries, so using a halfway step or not letting them up on the furniture would certainly have helped in these situations. I have recently helped a 15-year-old poodle called Cino who has arthritis and damaged his leg jumping off the couch. Cino responded very well to acupuncture and massage. I also showed his owner how to massage Cino’s muscles and use a heat pack for his arthritis. The good news is that Cino is no longer in pain and his owner now has a ramp to help him get up and down off the couch. Another dog I worked with recently was a 10-year-old English staffy called Alfie. He tore knee ligaments jumping off the bed and I was able to help rehabilitate Alfie without the need for surgery. A crucial part of Alfie’s rehabilitation was the personalised home care programme I developed for Alfie’s owners to follow. This helped Alfie recover faster and get back to running the house again... but no more jumping off the bed! The personalised face-to-face or online home care programmes are an important service I offer. Having the owner actively involved in the process of helping rehabilitate their dog can make a huge difference to the outcome... just like it did for Alfie. 6. A calm, relaxed home can help your dog feel less stressed Stress can affect our dogs in very similar ways to how it affects us. We can all recognise the impact stress can have on our own health. Our dogs are like sponges and will often show signs of stress when they see that their owners are stressed. Many dog owners testify that their dogs recognise and respond to their emotional states. So, doing all we can to minimise our own levels of stress is a great starting point to help keep our dogs calm and healthier. Being mindful of what your dog is exposed to in the home environment is important. Be aware of what the triggers are that stress your dog and then do all you can to minimise the impact of them if they are exposed to them. The key to a relaxed home environment for your dog always starts with a relaxed dog owner.

7 tips to make fresh flowers last longer

It’s always such a nice treat to have fresh flowers in the house – whether they’ve been bought for you by a special someone, you’ve treated yourself, or you’ve just cut them straight from your very own garden. But many people don’t know the correct way to look after a bunch of flowers to ensure they get to enjoy their beauty for as long as possible. So here are some simple tips to remember. <ol> <li>Start with the right kind of vase. Don’t try to cram too many flowers into a small vase – make sure the flowers have room to open fully so you can see as much of them as possible.</li> <li>Remove any low-hanging leaves. You don’t want any leaves to be sitting in the water, so be sure to prune them before putting your bouquet into your vase.</li> <li>Change the water daily. Flowers don’t like to sit in the same water day after day.</li> <li>Trim the stems. Every few days, trim the stems a little, cutting at an angle.</li> <li>Keep the flowers away from direct heat and sunlight. A room that is too warm will lead to wilted flowers, so be sure to choose somewhere that stays cool if possible. If you really want to stretch things, consider keeping the flowers in your fridge when you’re not in the house.</li> <li>When flowers start to wilt, remove any that don’t look so hot and transfer the bouquet to a smaller vase to freshen things up.</li> <li>If you’re left with just one or two late-opening blooms, you can float it in a decorative teacup full of water.</li> </ol> Image: Getty

Why the "just one drink a day" excuse no longer cuts it

According to a new study, those who have one standard drink a day are putting themselves at risk of permanent brain damage. The study of almost 21,000 people, published in the PLOS Medicine journal, found that consumption of seven or more units of alcohol per week is associated with higher iron levels in the brain. More iron in the brain is also linked to Alzheimer's and Parkinson's disease and is a potential mechanism for alcohol-related cognitive decline. The participants reported their own alcohol consumption, and their brains were scanned using magnetic resonance imaging (MRI). Of those participants, 7,000 of them also had MRIs on their livers imaged to see the levels of systemic iron. They were also required to complete a few tasks to assess their cognitive and motor function. The participants' average age was 55 years old and 48.6 per cent were female. Anya Topiwala of the University of Oxford, United Kingdom, and her colleagues found that alcohol consumption above seven units per week led to higher iron levels in basal ganglia - the part of the brain that helps with movement. “Markers of higher basal ganglia iron associated with slower executive function, lower fluid intelligence, and slower reaction times,” the study reported. “Iron accumulation in some brain regions was associated with worse cognitive function.” They concluded that moderate alcohol consumption is associated with higher iron levels in the brain.

Vaccine status no longer required

International travellers to Australia will no longer be required to submit their covid vaccine status. Chief Medical Officer Paul Kelly amended the Biosecurity Act 2015 which will come into effect from July 6. “The Australian Government makes decisions on COVID related issues after considering the latest medical advice,” Health Minister Mark Butler said. “The Chief Medical Officer has advised it is no longer necessary for travellers to declare their vaccine status as part of our management of COVID. “Unvaccinated Australians, as well as certain groups of visa holders, have been able to travel to Australia for some time. “We will continue to act on the medical advice as needed.” Travellers however must still comply with the Covid-19 rules of airlines, including states and territories, and other countries. This currently includes wearing masks on inbound international flights. State and territory orders mandating masks on domestic flights also remain in place. Image: Shutterstock

Moral injury: what happens when exhausted health workers can no longer provide the care they want for their patients

Healthcare workers in New Zealand already face life-and-death decisions daily. But as multiple winter illnesses add pressure to a system already stretched by COVID, staff now also have to deal with <a href="https://www.stuff.co.nz/national/politics/local-democracy-reporting/300534812/covid19-union-and-frontline-worker-say-staff-at-middlemore-hospital-facing-increasing-abuse" target="_blank" rel="noopener">daily abuse</a>, acute <a href="https://www.newshub.co.nz/home/new-zealand/2022/05/christchurch-hospital-cancels-surgeries-as-it-hits-112-pct-capacity.html" target="_blank" rel="noopener">staff shortages</a> and <a href="https://www.1news.co.nz/2022/06/17/dhb-clashes-with-union-over-stretched-palmerston-north-ed/" target="_blank" rel="noopener">unsafe working conditions</a>. At times, they cannot provide the care they would like for their patients. The impact on health workers is often described as <a href="https://www.nzherald.co.nz/rotorua-daily-post/news/great-minds-health-workers-on-covid-19-frontlines-burnt-and-bled-by-two-years-of-virus/T7JXOXGXEKKCICUNOMUJYT4QWM/" target="_blank" rel="noopener">stress and burnout</a>. The consequences of this prolonged pressure can be seen in the number of <a href="https://www.nzdoctor.co.nz/article/undoctored/acem-welcomes-111b-health-nz-budget-urges-fixes-health-workforce-crisis" target="_blank" rel="noopener">doctors</a>, <a href="https://www.nzherald.co.nz/nz/nursing-shortage-nurses-broken-while-sector-faces-thousands-of-vacancies/L7NUXOPG4AB472OKXOH5QJSUMU/" target="_blank" rel="noopener">nurses</a> and other <a href="https://capsulenz.com/be/therapist-shortage-nz/" target="_blank" rel="noopener">health professionals</a> leaving their jobs for overseas positions and the private sector, or being lost to their professions completely. Many of these healthcare workers may well be suffering from a more serious form of psychological distress than burnout: moral injury. <a href="https://www.phoenixaustralia.org/wp-content/uploads/2020/07/Moral-Stress-Healthcare-Workers-COVID-19-Guide-to-Moral-Injury.pdf" target="_blank" rel="noopener">Moral injury</a> refers to the psychological, social and spiritual impact of events on a person who holds strong values (such as caring for patients) and operates in high-stakes situations (hospital emergency care), but has to act in a way inconsistent with those values. Examples include having to turn patients away despite them being in pain or discomfort; being unable to provide adequate care due to staff shortages; having to care for a dying patient isolated from their loved ones while wearing full protective gear. Symptoms of moral injury can include strong feelings of guilt and shame (about not being able to uphold healthcare values, for example) as well as high levels of anger and contempt towards the system that prevents proper care. High levels of self-criticism, loss of trust in people and organisations and a weakening of personal relationships are further <a href="https://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366(21)00113-9/fulltext" target="_blank" rel="noopener">symptoms</a> of moral injury. It can be viewed as a <a href="https://www.afta.org/wp-content/uploads/2019/07/Physicians-aren%E2%80%99t-%E2%80%98burning-out.%E2%80%99-They%E2%80%99re-suffering-from-moral-injury..pdf" target="_blank" rel="noopener">more severe form of burnout</a>. But while burnout can happen in most workplaces, moral injury requires the three core components listed above. From war to the operating table The term moral injury arose in <a href="https://www.ptsd.va.gov/professional/treat/cooccurring/moral_injury.asp" target="_blank" rel="noopener">military psychology</a> to refer to situations where, for example, soldiers were unable to intervene to save lives in case they risked breaching the rules of engagement. More recently, the term has been adapted to apply to healthcare. Viewing the experiences of health workers through this lens can help us understand why they may experience a seesawing emotional state and the confusing conflict of simultaneously wanting to be at work while wishing they were anywhere but. For healthcare workers, understanding the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6752815/#:%7E:text=Over%20time%2C%20these%20repetitive%20insults,is%20in%20some%20way%20deficient" target="_blank" rel="noopener">concept of moral injury</a> may help reframe it as something that is happening to them rather than because they don’t have the skills to cope. The latter can sometimes be a mistaken implication of the term burnout. <figure class="align-center "><img src="https://images.theconversation.com/files/471254/original/file-20220627-22-u7c2tg.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/471254/original/file-20220627-22-u7c2tg.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/471254/original/file-20220627-22-u7c2tg.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/471254/original/file-20220627-22-u7c2tg.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/471254/original/file-20220627-22-u7c2tg.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/471254/original/file-20220627-22-u7c2tg.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/471254/original/file-20220627-22-u7c2tg.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Exhausted nurse" /><figcaption>Staff shortages can take health workers beyond exhaustion and burnout. Getty Images</figcaption></figure> While healthcare workers are largely at the mercy of the organisations they work for, there are some steps individuals can take to alleviate moral injury. Firstly, simply recognising they may be suffering from this condition can reduce confusion and validate their experiences. Secondly, reconnecting back to an individual’s values and beliefs can help refocus and re-energise, at least temporarily. Reminding themselves why they got into this job in the first place is a useful place to start. Organisational responses Organisations and businesses must play a lead role in preventing and treating moral injury. Many of the factors leading to it (lack of resources or staff, a pandemic or peak flu season) are outside the control of individuals. Most modern businesses will be aware they have a legal responsibility under the 2015 <a href="https://www.legislation.govt.nz/act/public/2015/0070/latest/DLM5976660.html" target="_blank" rel="noopener">Health and Safety at Work Act</a> to look after their employees’ mental and physical well-being. At a high level, organisations can advocate for systemic change and increases in funding and resourcing, where needed. But these higher-level changes take time to achieve. In the meantime, it is important healthcare workers are protected and supported. Broad steps an organisation can take to prevent or reduce moral injury include removing the burden of difficult ethical decisions from frontline workers and instead adopting evidence-based policies to guide an organisation-wide response. Where possible, rotating staff between high and low-stress environments may help. Providing funding for workers to access professional psychological supervision is another practical step businesses can consider. At a team level, it can be helpful to have leaders who are visible, validating and can help make sense of the moral conflict. Leaders can also play a role in keeping alive professional values and modelling their own struggles with the situation. The general public also has a role to play in supporting healthcare workers. Any steps we can take to protect our own health and thereby reduce pressure on the system can have a cumulative effect on the well-being of doctors, nurses and allied health clinicians. The health of our nation rests with those who work in this field and it is in all our interest that their health is protected and prioritised.<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/185485/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dougal-sutherland-747623" target="_blank" rel="noopener">Dougal Sutherland</a>, Clinical Psychologist, <a href="https://theconversation.com/institutions/te-herenga-waka-victoria-university-of-wellington-1200" target="_blank" rel="noopener">Te Herenga Waka — Victoria University of Wellington</a> This article is republished from <a href="https://theconversation.com" target="_blank" rel="noopener">The Conversation</a> under a Creative Commons license.

Do optimistic women live longer? New study seems to find it so

<div class="copy"> A positive outlook makes you feel better – but does it make you healthier? A study of over 150,000 US women has found a link between optimism and longevity. The study, which was <a href="https://doi.org/10.1111/jgs.17897" target="_blank" rel="noreferrer noopener">published</a> in Journal of the American Geriatrics Society, examined data from the <a href="https://www.whi.org/" target="_blank" rel="noreferrer noopener">Women’s Health Initiative</a>, a long-term study that enrolled 161,808 postmenopausal US women between 1993 and 1998. At enrolment, participants in the study completed (among other things) a test that measured their optimism. The researchers took this data from 159,255 of the participants, and compared it to their lifespan. (Study participants who died less than two years after enrolment were excluded from the analysis, on the grounds that their health may have affected their optimism, as were participants who didn’t complete the test.) <div class="newsletter-box"> <div id="wpcf7-f6-p194387-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> </div> </div> The researchers found that, across every racial and ethnic group in the study, higher optimism was associated with a longer lifespan. Lifestyle accounted for about a quarter of this association, but the link was still evident even when lifestyle was taken into account. Other research has compared these optimism measures to other health factors in the past, but this is the first study to examine the race and ethnicity of the whole cohort. “Although optimism itself may be patterned by social structural factors, our findings suggest that the benefits of optimism for longevity may hold across racial and ethnic groups,” says lead author Hayami Koga, of the Harvard T.H. Chan School of Public Health, US. “Optimism may be an important target of intervention for longevity across diverse groups.” Image credits: Getty Images <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=194387&title=Do+optimistic+women+live+longer%3F+New+study+seems+to+find+it+so" width="1" height="1" /></div> <div id="contributors"> This article was originally published on <a href="https://cosmosmagazine.com/health/optimism-and-longevity/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Ellen Phiddian. </div>

Your morning cup of coffee could help you live longer

While coffee helps us function, it could also potentially be an elixir to a longer life. Drinking 1.5 to 3.5 cups of coffee per day, even with sugar, could help you live longer. An international team of scientists (and fellow coffee lovers) spent seven years looking at the caffeinated drinking habits of 171,000 participants from the UK, all of whom had no known heart disease or cancer. The authors found that participants who drank any amount of unsweetened coffee were 16% to 21% less likely to die within that seven-year period, compared to those who did not drink coffee. They also found that participants who liked their coffee sweet, drinking it with one teaspoon of sugar, had a 29% to 31% lower chance of passing away. Results were inconclusive for those who drank coffee with artificial sweetener. The researchers caution that for maximum benefits, coffee drinkers should consume no more than 3.5 cups per day, and limit the amount of sugar with each coffee. Based on this data, there is no need for most coffee drinkers to eliminate that cup of joe from their diet, but they should be cautious about ordering calorie-laden frappacinos! The study was published in Annals of Internal Medicine.
