Centenarian blood tests give hints of the secrets to longevity

<p><em><a href="https://theconversation.com/profiles/karin-modig-1473484">Karin Modig</a>, <a href="https://theconversation.com/institutions/karolinska-institutet-1250">Karolinska Institutet</a></em></p> <p>Centenarians, once considered rare, have become commonplace. Indeed, they are the <a href="https://www.weforum.org/agenda/2021/02/living-to-one-hundred-life-expectancy/">fastest-growing demographic group</a> of the world’s population, with numbers roughly doubling every ten years since the 1970s.</p> <p>How long humans can live, and what determines a long and healthy life, have been of interest for as long as we know. Plato and Aristotle discussed and <a href="https://pubmed.ncbi.nlm.nih.gov/12092789/">wrote about the ageing process</a> over 2,300 years ago.</p> <p>The pursuit of understanding the secrets behind exceptional longevity isn’t easy, however. It involves <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7105197/">unravelling the complex interplay</a> of genetic predisposition and lifestyle factors and how they interact throughout a person’s life. Now our recent study, <a href="https://link.springer.com/article/10.1007/s11357-023-00936-w">published in GeroScience</a>, has unveiled some common biomarkers, including levels of cholesterol and glucose, in people who live past 90.</p> <p>Nonagenarians and centenarians have long been of intense interest to scientists as they may help us understand how to live longer, and perhaps also how to age in better health. So far, studies of centenarians have often been small scale and focused on a selected group, for example, excluding centenarians who live in care homes.</p> <h2>Huge dataset</h2> <p>Ours is the largest study comparing biomarker profiles measured throughout life among exceptionally long-lived people and their shorter-lived peers to date.</p> <p>We compared the biomarker profiles of people who went on to live past the age of 100, and their shorter-lived peers, and investigated the link between the profiles and the chance of becoming a centenarian.</p> <p>Our research included data from 44,000 Swedes who underwent health assessments at ages 64-99 - they were a sample of <a href="https://pubmed.ncbi.nlm.nih.gov/28158674/">the so-called Amoris cohort</a>. These participants were then followed through Swedish register data for up to 35 years. Of these people, 1,224, or 2.7%, lived to be 100 years old. The vast majority (85%) of the centenarians were female.</p> <p>Twelve blood-based biomarkers related to inflammation, metabolism, liver and kidney function, as well as potential malnutrition and anaemia, were included. All of these <a href="https://www.nature.com/articles/s41591-019-0719-5">have been associated</a> with ageing or mortality in previous studies.</p> <p>The biomarker related to inflammation was uric acid – a waste product in the body caused by the digestion of certain foods. We also looked at markers linked to metabolic status and function including total cholesterol and glucose, and ones related to liver function, such as alanine aminotransferase (Alat), aspartate aminotransferase (Asat), albumin, gamma-glutamyl transferase (GGT), alkaline phosphatase (Alp) and lactate dehydrogenase (LD).</p> <p>We also looked at creatinine, which is linked to kidney function, and iron and total iron-binding capacity (TIBC), which is linked to anaemia. Finally, we also investigated albumin, a biomarker associated with nutrition.</p> <h2>Findings</h2> <p>We found that, on the whole, those who made it to their hundredth birthday tended to have lower levels of glucose, creatinine and uric acid from their sixties onwards. Although the median values didn’t differ significantly between centenarians and non-centenarians for most biomarkers, centenarians seldom displayed extremely high or low values.</p> <p>For example, very few of the centenarians had a glucose level above 6.5 earlier in life, or a creatinine level above 125.</p> <p>For many of the biomarkers, both centenarians and non-centenarians had values outside of the range considered normal in clinical guidelines. This is probably because these guidelines are set based on a younger and healthier population.</p> <p>When exploring which biomarkers were linked to the likelihood of reaching 100, we found that all but two (alat and albumin) of the 12 biomarkers showed a connection to the likelihood of turning 100. This was even after accounting for age, sex and disease burden.</p> <p>The people in the lowest out of five groups for levels of total cholesterol and iron had a lower chance of reaching 100 years as compared to those with higher levels. Meanwhile, people with higher levels of glucose, creatinine, uric acid and markers for liver function also decreased the chance of becoming a centenarian.</p> <p>In absolute terms, the differences were rather small for some of the biomarkers, while for others the differences were somewhat more substantial.</p> <p>For uric acid, for instance, the absolute difference was 2.5 percentage points. This means that people in the group with the lowest uric acid had a 4% chance of turning 100 while in the group with the highest uric acid levels only 1.5% made it to age 100.</p> <p>Even if the differences we discovered were overall rather small, they suggest a potential link between metabolic health, nutrition and exceptional longevity.</p> <p>The study, however, does not allow any conclusions about which lifestyle factors or genes are responsible for the biomarker values. However, it is reasonable to think that factors such as nutrition and alcohol intake play a role. Keeping track of your kidney and liver values, as well as glucose and uric acid as you get older, is probably not a bad idea.</p> <p>That said, chance probably plays a role at some point in reaching an exceptional age. But the fact that differences in biomarkers could be observed a long time before death suggests that genes and lifestyle may also play a role.<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/215166/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/karin-modig-1473484">Karin Modig</a>, Associate Professor, Epidemiology, <a href="https://theconversation.com/institutions/karolinska-institutet-1250">Karolinska Institutet</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why are my muscles sore after exercise? Hint: it’s nothing to do with lactic acid

<p><em><a href="https://theconversation.com/profiles/robert-andrew-robergs-435390">Robert Andrew Robergs</a>, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a> and <a href="https://theconversation.com/profiles/samuel-l-torrens-1476404">Samuel L. Torrens</a>, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a></em></p> <p>As many of us hit the gym or go for a run to recover from the silly season, you might notice a bit of extra muscle soreness.</p> <p>This is especially true if it has been a while between workouts.</p> <p>A common misunderstanding is that such soreness is due to lactic acid build-up in the muscles.</p> <p>Research, however, shows lactic acid has <a href="https://journals.physiology.org/doi/full/10.1152/physiol.00033.2017">nothing to do with it</a>. The truth is far more interesting, but also a bit more complex.</p> <h2>It’s not lactic acid</h2> <p>We’ve known for decades that lactic acid has <a href="https://pubmed.ncbi.nlm.nih.gov/27409551/">nothing to do with</a> muscle soreness after exercise.</p> <p>In fact, as one of us (Robert Andrew Robergs) has long <a href="https://journals.physiology.org/doi/full/10.1152/ajpregu.00114.2004">argued</a>, cells produce lactate, not lactic acid. This process actually <a href="https://journals.physiology.org/doi/full/10.1152/physiol.00033.2017">opposes</a> not causes the build-up of acid in the muscles and bloodstream.</p> <p>Unfortunately, historical inertia means people still use the term “lactic acid” in relation to exercise.</p> <p>Lactate <a href="https://www.science.org/doi/10.1126/science.1101141">doesn’t cause major problems</a> for the muscles you use when you exercise. You’d probably be <a href="https://journals.physiology.org/doi/full/10.1152/ajpregu.00114.2004?url_ver=Z39.88-2003&amp;rfr_id=ori%3Arid%3Acrossref.org&amp;rfr_dat=cr_pub++0pubmed&amp;">worse off</a> without it due to other benefits to your working muscles.</p> <p>Lactate isn’t the reason you’re sore a few days after upping your weights or exercising after a long break.</p> <p>So, if it’s not lactic acid and it’s not lactate, what is causing all that muscle soreness?</p> <h2>Muscle pain during and after exercise</h2> <p>When you exercise, a lot of chemical reactions occur in your muscle cells. All these chemical reactions accumulate products and by-products which cause water to enter into the cells.</p> <p>That causes the pressure inside and between muscle cells to increase.</p> <p>This pressure, combined with the movement of molecules from the muscle cells can stimulate nerve endings and cause <a href="https://www.sportsmed.theclinics.com/article/S0278-5919(11)00099-8/fulltext">discomfort</a> during exercise.</p> <p>The pain and discomfort you sometimes feel hours to days after an unfamiliar type or amount of exercise has a different list of causes.</p> <p>If you exercise beyond your usual level or routine, you can cause microscopic damage to your muscles and their connections to tendons.</p> <p>Such damage causes the release of ions and other molecules from the muscles, causing localised swelling and stimulation of nerve endings.</p> <p>This is sometimes known as “<a href="https://www.sportsmed.theclinics.com/article/S0278-5919(11)00099-8/fulltext">delayed onset muscle soreness</a>” or DOMS.</p> <p>While the damage occurs during the exercise, the resulting response to the injury builds over the next one to two days (longer if the damage is severe). This can sometimes cause pain and difficulty with normal movement.</p> <h2>The upshot</h2> <p>Research is clear; the discomfort from delayed onset muscle soreness has nothing to do with <a href="https://scholar.google.com/citations?user=UVjRNSUAAAAJ&amp;view_op=view_citation&amp;citation_for_view=UVjRNSUAAAAJ:J_g5lzvAfSwC">lactate</a> or <a href="https://journals.physiology.org/doi/full/10.1152/physiol.00033.2017">lactic acid</a>.</p> <p>The good news, though, is that your muscles adapt rapidly to the activity that would initially cause delayed onset muscle soreness.</p> <p>So, assuming you don’t wait too long (more than roughly two weeks) before being active again, the next time you do the same activity there will be much less damage and discomfort.</p> <p>If you have an exercise goal (such as doing a particular hike or completing a half-marathon), ensure it is realistic and that you can work up to it by training over several months.</p> <p>Such training will gradually build the muscle adaptations necessary to prevent delayed onset muscle soreness. And being less wrecked by exercise makes it more enjoyable and more easy to stick to a routine or habit.</p> <p>Finally, remove “lactic acid” from your exercise vocabulary. Its supposed role in muscle soreness is a myth that’s hung around far too long already.<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/214638/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/robert-andrew-robergs-435390"><em>Robert Andrew Robergs</em></a><em>, Associate Professor - Exercise Physiology, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a> and <a href="https://theconversation.com/profiles/samuel-l-torrens-1476404">Samuel L.

Bees have appeared on coins for millennia, hinting at an age-old link between sweetness and value

One approach to this question comes from the field of neuro-aesthetics, which seeks to understand our tastes by understanding the basic brain processes that underpin aesthetic appreciation.</p> <p>From this perspective, it seems likely the sweet taste of honey – which indicates the large amount of sugar it delivers – promotes positive neural activity <a href="https://brill.com/view/journals/artp/10/1/article-p1_2.xml">associated with bees and honey</a>.</p> <p>Indeed, primatologist Jane Goodall once proposed that obtaining high-calorie nutrition from bee honey may have been <a href="https://www.sciencedirect.com/science/article/abs/pii/S0066185668800032">an important step</a> in the cognitive development of primates.</p> <p>Our brain may thus be pre-adapted to liking bees due to their association with the sweet taste of honey.

Who’s taking COVID antivirals like Paxlovid? Hint: it helps if you’re rich

<p><em><a href="https://theconversation.com/profiles/nicole-allard-1349026">Nicole Allard</a>, <a href="https://theconversation.com/institutions/the-peter-doherty-institute-for-infection-and-immunity-2255">The Peter Doherty Institute for Infection and Immunity</a></em></p> <p>When it comes to COVID, people living in disadvantaged communities are hit with a triple whammy. First, they’re <a href="https://www.aihw.gov.au/reports-data/health-conditions-disability-deaths/covid-19/overview">more likely</a> to get infected, and when sick, are more likely to have serious disease. Second, they’re <a href="https://theconversation.com/first-covid-hit-disadvantaged-communities-harder-now-long-covid-delivers-them-a-further-blow-183908">more likely</a> to develop long COVID. Third, our <a href="https://www.mja.com.au/journal/2023/218/10/access-oral-covid-19-antivirals-community-are-eligibility-criteria-and-systems">recent research</a> suggests they’re less likely to get antivirals and when they do, it’s on average later.</p> <p>We’ve just <a href="https://www.mja.com.au/journal/2023/218/10/access-oral-covid-19-antivirals-community-are-eligibility-criteria-and-systems">published the data</a> to map how disadvantage is linked with access to COVID antiviral drugs you can take at home.</p> <p>Here’s why our findings matter and what we can do to level the playing field for this critical part of Australia’s COVID response.</p> <h2>What we did and what we found</h2> <p>Our team looked at Victorian and national prescribing data trends for the oral antiviral medications eligible Australians can take at home – Paxlovid (nirmatrelvir/ritonavir) and Lagevrio (molnupiravir).</p> <p>My health department colleagues linked data from the Pharmaceutical Benefits Scheme with information from the Victorian health department’s COVID surveillance database. They then matched levels of socioeconomic disadvantage by postcode, according to criteria from the Australian Bureau of Statistics.</p> <p>Their analysis showed people living in the most disadvantaged postcodes were 15% less likely to receive oral antivirals compared with those in the most advantaged postcodes.</p> <p>Those in the most disadvantaged postcodes were supplied with the antivirals on average a day later (three days versus two days) than those in the most advantaged postcodes.</p> <p>There are some limitations to our analysis. Not everyone who tests for COVID reports their positive result. And we suspect there may be more under-reporting of infections in disadvantaged areas.</p> <p>Nevertheless, our findings about the influence of disadvantage on antiviral supply are not surprising. In the United States, there have been <a href="https://www.cdc.gov/mmwr/volumes/71/wr/mm7125e1.htm?utm">similar results</a>.</p> <h2>Why has this happened?</h2> <p>We know <a href="https://www.health.gov.au/health-alerts/covid-19/treatments/eligibility">early access to antivirals</a>, within the first five days of symptoms starting, is important to reduce the chances of severe disease and hospitalisation in those at risk.</p> <p>So why are people in disadvantaged areas less likely to have access to COVID antivirals? The answers are multiple and complex.</p> <p>Some relate to <a href="https://link.springer.com/article/10.1007/s11069-019-03584-6/tables/1">disadvantage</a> that existed before the pandemic – for instance, poverty, homelessness, lower levels of English or formal education, and being less likely to have a regular GP.</p> <p>Some factors relate specifically to antivirals. For instance, to access antivirals, you first have to know they exist and whether you might be eligible, then know how to access them and when. There may be out-of-pocket costs to see a GP to be assessed, then there’s the cost of filling the prescription, even with a concession card.</p> <h2>How can we address this?</h2> <p>We have an opportunity to address this inequity, whether that’s by addressing social determinants of health more broadly, or specifically related to antivirals access.</p> <p>Equity depends on continuing to address the structural inequalities in our health system that create barriers to people accessing primary health services, and tailoring responses to communities.</p> <p>For instance, earlier in the pandemic we saw funding to house homeless people, provide COVID-related health care to non-English speaking communities, and for people isolated at home. These initiatives need to continue.</p> <p>Other countries have also recognised the need for more equitable access to COVID antivirals. Initiatives have included:</p> <ul> <li> <p>COVID medicine <a href="https://phlgroup.co.uk/our-services/cmdu/">delivery units</a> in the United Kingdom. These identify, triage and arrange for high-risk people to receive antivirals at home</p> </li> <li> <p><a href="https://covid19.govt.nz/testing-and-isolation/if-you-have-covid-19/medicines-to-treat-covid-19">pharmacists prescribing antivirals</a> in New Zealand, and</p> </li> <li> <p>“<a href="https://aspr.hhs.gov/TestToTreat/Pages/default.aspx#:%7E:text=To%20find%20a%20participating%20Test%20to%20Treat%20site%20near%20you%3A&amp;text=Call%20the%20Centers%20for%20Disease,more%20than%20150%20other%20languages.">test to treat</a>” services in the US. This is where people can get tested, assessed and access antivirals in one spot, in one visit.</p> </li> </ul> <h2>What needs to happen next?</h2> <p>As <a href="https://theconversation.com/were-in-another-covid-wave-but-its-not-like-the-others-206493">COVID waves continue</a>, we must focus on reducing deaths and hospitalisations. Antiviral treatments are part of our armour and equity must drive our response.</p> <p>Our ongoing COVID response should be designed with consumer input, supported by an adequately funded public health system and be data driven. Here’s what needs to happen next:</p> <ul> <li> <p>encourage a tired public to see COVID testing as an important first step to accessing antiviral treatment, and why they should consider treatment</p> </li> <li> <p>address the health care inequality in primary care (for instance, boosting timely access to a GP people can afford to visit) by increasing resourcing in areas where we know there are gaps</p> </li> <li> <p>provide culturally safe health care, delivered in community languages, co-designed with community input</p> </li> <li> <p>evaluate current and future antiviral medications</p> </li> <li> <p>communicate up-to-date information to the public and health professionals about antivirals, particularity GPs</p> </li> <li> <p>access more data on the coverage and equity of antiviral COVID treatments, to help direct us to the gaps in the health system that need to be plugged.</p> </li> </ul> <h2>Why this matters now</h2> <p>For many of us in the past year, COVID has become another “cold” we encounter and may not even bother testing. Yet, we continue to see <a href="https://www.health.gov.au/health-alerts/covid-19/weekly-reporting">deaths and hospitalisations</a> across the country.</p> <p>Serious COVID infections continue to affect our most vulnerable people. These include elderly people, especially those over 80, First Nations people, people living with a disability and people who are socioeconomically disadvantaged.</p> <p>We have a chance to ensure antivirals are used to reduce existing disparities in hospitalisation and death – not to make them worse.<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/207822/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/nicole-allard-1349026">Nicole Allard</a>, Post doctoral researcher and medical epidemiologist, <a href="https://theconversation.com/institutions/the-peter-doherty-institute-for-infection-and-immunity-2255">The Peter Doherty Institute for Infection and Immunity</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Top 8 tips for composting

<p>Want to do something good for the earth that will save you money at the same time? Well, you should consider ditching fertilizer and make compost instead. For anyone new to composting, or for those who want to improve the composting skills, we’ve gathered a list of our top tips.</p> <p><strong>1. Get a quality bin</strong></p> <p>The alternative to building a compost heap in your garden, is to try a compost bin. They’re usually compact which makes them perfect for smaller gardens and yards.</p> <p><strong>2. Perfect placement</strong></p> <p>You’ll want to ensure you pick a spot that is level and well-drained spot so that any excess water can drain away easily. This also helps worms to get in and get on with the job of breaking down the content.</p> <p><strong>3. Put the worms to work</strong></p> <p>The humble worm is the perfect (and must-have) addition to any successful compost. They love the moist atmosphere of a compost heap, eating the waste material you put in and converting it into liquid feed and compost. The tiger worm is  great choice for any compost.</p> <p><strong>4. What to compost</strong></p> <p>Good things to compost include vegetable peelings, fruit waste, teabags, plant prunings and grass cuttings. All of these things break down quickly and provide important nitrogen as well as moisture. While slower to rot, it’s also good to include things such as cardboard egg boxes, scrunched up paper and fallen leaves as they provide vital fibre and carbon and also allow important air pockets to form in the mixture.</p> <p><strong>5. Forget these things</strong></p> <p>Meat or dairy products should never but put in your compost. Also, don’t dispose of any diseased plants, dog poo or cat litter, or babies’ nappies in your compost – these belong in the everyday bin. It’s also a good idea to avoid composting perennial weeds (such as dandelions and thistle) or weeds with seed heads.</p> <p><strong>6. Let it air out</strong></p> <p>Composts requires regular turning, which can be a tricky job without the right tools. Opt for something with a long handle and turn your compost as it helps to aerate and mix up the waste and cuttings, which leads to faster composting.</p> <p><strong>7. Add a booster</strong></p> <p>It’s a great idea to encourage the correct enzymes in your compost by using a activator. It helps to turn your grass, leaves and garden waste into dark, rich, crumbly compost in less than half the time.</p> <p><strong>8. Wait for it to be perfect </strong></p> <p>When your compost is ready you’ll have a dark brown, almost black soil-like layer at the bottom of your bin. It should have a spongy texture and will be rich in nutrients. When it’s ready, spread the compost over your flowerbeds this will greatly improve the soil quality by helping it retain moisture and suppressing weeds.</p> <p><em>Image credits: Getty Images </em></p>

Clever ways to reuse dryer lint around the house

<h2>Start a fire</h2> <p>Dryer lint is flammable, which is why we’re urged to clean out the trap after each load of laundry. Collect it in a sealed jar to use as tinder the next time you start a fire in your backyard fire pit. For a self-contained fire starter, stuff cardboard toilet paper rolls with lint.</p> <h2>Use as mulch</h2> <p>You can add dryer lint as a mulch around potted plants as long as you’re not using dryer sheets, which may leave an unwanted chemical residue.</p> <h2>Prevent erosion</h2> <p>When spread out and dampened with water, dryer lint can form a barrier to protect soil from erosion. If you don’t like the look of soggy lint, use the lint as an under-layer and cover with decorative stones.</p> <h2>Discourage weeds</h2> <p>Just like a thick layer of lint can prevent erosion, a base of dryer lint can prevent weeds as well. Use it as a substitute for landscape fabric and top with a decorative mulch.</p> <h2>Add to compost</h2> <p>Lint from natural fibres like cotton and wool is biodegradable, so you can add it to the compost pile as a source of carbon.</p> <h2>Oil down tools</h2> <p>Use a clump of dryer lint to apply linseed oil to wooden-handle tools to keep them from cracking, and to metal parts (after cleaning) to keep them from rusting. Then toss the lint in the garbage.</p> <h2>Line garden containers</h2> <p>Line the bottom of a plant pot with dryer lint to keep soil from spilling out the drainage hole. The lint layer will also act as a blotter, soaking up extra moisture and making it available for the roots later. This container gardening tip is not recommended for cacti, succulents and other plants that like soil on the dry side.</p> <h2>Soak up spills</h2> <p>Keep a jar of dryer lint in the garage to use when you need to soak up oil spills.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/diy-tips/clever-ways-to-reuse-dryer-lint-around-the-house" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

5 satisfying ways to de-clutter and get rid of everything you don’t want

<p>Instead of letting your old belongings gather dust in the spare room, why not make it a priority to remove those old things that you don’t use anymore. Follow our tips below where we show you five different ways to get rid of unwanted items (and maybe even make a little money in the process).</p> <p><strong>Sell, sell, sell</strong></p> <p>eBay is a great place to start for items such as stereos, CDs, vinyl, mobile phones, or clothing (even better if it is a well-known brand).</p> <p>When it comes to books, try checking out Amazon as they have a huge market for second hand items. It’s best to use this for quality books or rare items that have people looking for them. Old cookbooks or romance novels are best offered to the charity shop.</p> <p>You can easily move your quality pieces of furniture through antiques stores or local second hand shops. Most offer a pick-up service for larger items that they want to sell.</p> <p>If you have lots of odds and ends, a garage sale can be a good option. If you’re not sure that you have enough, consider asking a friend or neighbour if they want to host a sale with you.</p> <p><strong>Give a gift</strong></p> <p>If you’re holding onto things because they are worth something, but you don’t actually need or want them – why not give them away as a gift?</p> <p>Your old record collection or suitcase full of toy cars may be just gathering dust but would be well received by the right person.</p> <p>The only exception is an item such as artwork which has appreciated significantly in value while you owned it. In this case the recipient would owe capital gains tax if they sold it later.</p> <p><strong>Make a donation</strong></p> <p>Your local charity shop will always be happy to take donations of good quality clothing, blankets, shoes, toys and homewares. You can feel good knowing that you are helping needy people in your local area. Some charity stores can’t accept electronics or large pieces of furniture, so it’s best to check before you arrive with a loaded up trailer.</p> <p>You can also donate books and recent magazines to your local library or hospital.</p> <p><strong>Liquidate It</strong></p> <p>If you want to get rid of all of the furniture (for instance if you are selling a house of a deceased relative) you could consider using a liquidator. These businesses take care of the sale of each item and then take a percentage of the sales. Be sure to ask around for any recommendations before you choose one, as it’s always advisable to go with a liquidator with a good reputation.</p> <p><strong>Toss It</strong></p> <p>If it’s not really something that you can sell or donate, the last stop is to throw it out. Be sure to recycle anything that you can – and check with your local council as most offer a free clear up service at least once a year to save you a trip to the local tip.</p> <p><em>Images: Getty</em></p>

3 little-known reasons why plastic recycling could actually make things worse

<p><em><a href="https://theconversation.com/profiles/pascal-scherrer-230971">Pascal Scherrer</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a></em></p> <p>This week in Paris, negotiators from around the world are <a href="https://www.unep.org/events/conference/second-session-intergovernmental-negotiating-committee-develop-international">convening</a> for a United Nations meeting. They will tackle a thorny problem: finding a globally binding solution for plastic pollution.</p> <p>Of the staggering <a href="https://stats.oecd.org/viewhtml.aspx?datasetcode=PLASTIC_USE_6&amp;lang=en">460 million tonnes of plastic used globally in 2019 alone</a>, much is used only once and thrown away. About <a href="https://www.oecd.org/environment/plastic-pollution-is-growing-relentlessly-as-waste-management-and-recycling-fall-short.htm">40% of plastic waste</a> comes from packaging. Almost two-thirds of plastic waste comes from items with lifetimes of less than five years.</p> <p>The plastic waste that escapes into nature persists and breaks up into smaller and smaller pieces, <a href="https://www.science.org/doi/10.1126/sciadv.1700782">eventually becoming microplastics</a>. Plastics now contaminate virtually every environment, from <a href="https://www.theguardian.com/environment/2020/nov/20/microplastic-pollution-found-near-summit-of-mount-everest">mountain peaks to oceans</a>. Plastic has entered vital systems such as our food chain and even the human <a href="https://www.theguardian.com/environment/2022/mar/24/microplastics-found-in-human-blood-for-first-time">blood stream</a>.</p> <p>Governments and industry <a href="https://www.un.org/en/climatechange/nations-agree-end-plastic-pollution">increasingly acknowledge</a> the urgent need to reduce plastic pollution. They are introducing <a href="https://apco.org.au/the-australian-packaging-covenant">rules and incentives</a> to help businesses stop using single-use plastics while also encouraging collection and recycling.</p> <p>As a sustainability researcher, I explore opportunities to <a href="https://www.scu.edu.au/research/zerowaste/">reduce plastic waste </a>in sectors such as tourism, hospitality and meat production. I know how quickly we could make big changes. But I’ve also seen how quick-fix solutions can create complex future problems. So we must proceed with caution.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">The best way to tackle plastic pollution is to prevent it in the first place.</p> <p>Governments, businesses, civil society, and academia can all be part of the solution to <a href="https://twitter.com/hashtag/BeatPlasticPollution?src=hash&amp;ref_src=twsrc%5Etfw">#BeatPlasticPollution</a>.</p> <p>Join in this <a href="https://twitter.com/hashtag/WorldEnvironmentDay?src=hash&amp;ref_src=twsrc%5Etfw">#WorldEnvironmentDay</a>: <a href="https://t.co/ENu9UG82kz">https://t.co/ENu9UG82kz</a> <a href="https://t.co/1p5G0183uh">pic.twitter.com/1p5G0183uh</a></p> <p>— UN Environment Programme (@UNEP) <a href="https://twitter.com/UNEP/status/1660873190577680384?ref_src=twsrc%5Etfw">May 23, 2023</a></p></blockquote> <h2>Plastic avoidance is top priority</h2> <p>We must urgently eliminate waste and build a so-called “<a href="https://ellenmacarthurfoundation.org/topics/circular-economy-introduction/overview">circular economy</a>”. For plastics, that means reuse or recycling back into the same type of plastic, not lower grade plastic. The plastic can be used to make similar products that then can be recycled again and again.</p> <p>This means plastics should only be used where they can be captured at their end of life and recycled into a product of the same or higher value, with as little loss as possible.</p> <p>Probably the only example of this to date is the recycling of PET (polyethylene terephthalate) soft-drink bottles in Norway and Switzerland. They boast recovery rates of <a href="https://phys.org/news/2020-02-norway-bottles-plastic-fantastic.html">97%</a> and <a href="https://houseofswitzerland.org/swissstories/environment/switzerland-leads-way-pet-recycling">95%</a> respectively.</p> <p>The <a href="https://wastewise.be/2014/11/ad-lansink/">waste management pyramid</a> below shows how to prioritise actions to lessen the waste problem. It is particularly relevant to single-use plastics. Our top priority, demanding the biggest investment, is prevention and reduction through redesign of products.</p> <p>Where elimination is not yet achievable, reuse solutions or recycling to the same or higher-level products can be sought to make plastics circular.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=406&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=406&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=406&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=510&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=510&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/527407/original/file-20230522-21-y07zqy.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=510&amp;fit=crop&amp;dpr=3 2262w" alt="Inverted pyramid diagram showing waste management priorities" /><figcaption><span class="caption">In the inverted pyramid of waste management priorities, downcycling is almost the last resort.</span> <span class="attribution"><span class="source">Pascal Scherrer</span></span></figcaption></figure> <p>Unfortunately, a lack of high-quality reprocessing facilities means plastic waste keeps growing. In Australia, plastic is largely “downcycled”, which means it is recycled into lower quality plastics.</p> <p>This can seem like an attractive way to deal with waste-plastic stockpiles, particularly after the recent collapse of soft-plastics recycler <a href="https://theconversation.com/redcycles-collapse-is-more-proof-that-plastic-recycling-is-a-broken-system-194528">RedCycle</a>. But downcycling risks doing more harm than good. Here are three reasons why:</p> <h2>1. Replacing wood with recycled plastics risks contaminating our wildest natural spaces</h2> <p>An increasing number of benches, tables, bollards and boardwalks are being made from recycled plastic. This shift away from timber is touted as a sustainable step - but caution is warranted when introducing these products to pristine areas such as national parks.</p> <p>Wood is naturally present in those areas. It has a proven record of longevity and, when degrading, does not introduce foreign matter into the natural system.</p> <p>Swapping wood for plastic <a href="https://www.sciencedirect.com/science/article/abs/pii/S0269749122019510?via%3Dihub">may introduce microplastics</a> into the few remaining places relatively free of them. Replacing wood with downcycled plastics also risks plastic pollution through weathering or fire.</p> <h2>2. Taking circular plastics from their closed loop to meet recycled-content targets creates more waste</h2> <p>Clear PET bottles used for beverages are the most circular plastic stream in Australia, approaching a 70% recovery rate. When these bottles are recycled back into clear PET bottles, they are circular plastics.</p> <p>However, the used PET bottles are increasingly being turned into meat trays, berry punnets and <a href="https://www.praise.com.au/faqs-100-recycled-bottles">mayonnaise jars</a> to help producers meet the <a href="https://apco.org.au/national-packaging-targets">2025 National Packaging Target</a> of 50% recycled content (on average) in packaging.</p> <p>The problem is the current industry <a href="https://anzpacplasticspact.org.au/wp-content/uploads/2021/06/Recovered-Polymer-Specifications_FINAL_June2021d.pdf">specifications for plastics recovery</a> allow only downcycling of these trays, punnets and jars. This means that circular PET is removed from a closed loop into a lower-grade recovery stream. This leads to non-circular downcycling and more plastic sent to landfill.</p> <h2>3. Using “compostable” plastics in non-compostable conditions creates still more plastic pollution</h2> <p>Increasingly, plastics are labelled as compostable and biodegradable. However, well-intended use of compostable plastics can cause long-term plastic pollution.</p> <p>At the right temperature with the right amount of moisture, compostable plastics breakdown into soil. But if the conditions are not “just right”, they won’t break down at all.</p> <p>For example, when a landscape architect or engineer uses a “compostable” synthetic fabric instead of a natural alternative (such as coir or jute mats) they can inadvertently introduce persistent plastics into the environment. This is because the temperature is not hot enough for the synthetic mat to break down.</p> <p>We must also <a href="https://documents.packagingcovenant.org.au/public-documents/Considerations%20for%20Compostable%20Packaging">differentiate</a> between “home compostable” and “commercially compostable”. Commercial facilities are more effective at composting because they operate under more closely controlled conditions.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Plastic pollution could reduce by 80% by 2040 if governments and companies make policy and market shifts using existing technologies.</p> <p>OUT NOW – UNEP’s new report provides a pathway for nations to <a href="https://twitter.com/hashtag/BeatPlasticPollution?src=hash&amp;ref_src=twsrc%5Etfw">#BeatPlasticPollution</a>: <a href="https://t.co/dcfBkZaOfN">https://t.co/dcfBkZaOfN</a> <a href="https://t.co/iSQ9QSpYC1">pic.twitter.com/iSQ9QSpYC1</a></p> <p>— UN Environment Programme (@UNEP) <a href="https://twitter.com/UNEP/status/1658419925638152192?ref_src=twsrc%5Etfw">May 16, 2023</a></p></blockquote> <h2>Learning from our mistakes</h2> <p>Clearly, we need to reduce our reliance on plastics and shift away from linear systems – including recycling into lower-grade products.</p> <p>Such downcycling may have a temporary role in dealing with existing plastic in the system while circular recycling capacity is being built. But we must not develop downcycling “solutions” that need a long-term stream of plastic waste to remain viable.</p> <p>What’s more, downcycling requires constantly finding new markets for their lower-grade products. Circular systems are more robust.</p> <p>So, to the negotiators in Paris, yes the shift to a circular plastics economy is urgent. But beware of good intentions that could ultimately make things worse.<!-- Below is The Conversation's page counter tag.

21 more organising tips you'll wish you knew all along

<p><strong>Give in to the piles</strong></p> <p>“For people who chronically pile papers instead of filing them, ditch your filing cabinet. Instead, keep your piles but make them a little more structured by putting them into clear bins and then labelling them by category. It’s best if bins are transparent—either wire or acrylic—because if you’re a piler then you also probably have a visual memory. Labelling helps other people interact with your piling system.” —Kelly McMenamin and Katie McMenamin, co-authors of Organise Your Way: Simple Strategies for Every Personality</p> <p><strong>Hang everything</strong></p> <p>“Consider hanging almost all of your clothes. (You can use a double hanger to increase hanging space.) This helps you see everything you have so you know exactly what’s there and what you need. Drawers should be reserved for socks and underwear only.” —Kelly McMenamin and Katie McMenamin</p> <p><strong>Don’t underestimate how draining clutter can be</strong></p> <p>“Being surrounded by a lot of stuff can wear you down, physically and emotionally. Your home should be a reflection of items that truly hold meaning for you – either because you really like them or because there’s a special memory attached to them. Don’t hang onto unused picture frames, knick-knacks, plates, bowls, vases and other items you don’t have out on display or use. And remember, just because it’s hidden in a closet doesn’t mean it won’t add to that overwhelmed feeling you have as you still have to take care of it.” —Jeffrey Welder</p> <p><strong>Note how your taste changes</strong></p> <p>“Just because you loved something once doesn’t mean you still have to love it ten years later. Times change, people change, and trends change, and there’s nothing wrong with letting things go that no longer make you happy.” —Jeffrey Welder</p> <p><strong>Over-the-door shoe organisers aren’t just for shoes</strong></p> <p>“Hanging shoe organisers are a handy tool to keep clutter off floors and shelves, with uses for every room of your house. Try hanging one in your laundry room to organise all of your cleaning supplies. Or put one on your pantry door as the pouches are the perfect size to organise small boxes and gravy packets. Hang one in your bathroom to organise makeup and other toiletries. Use one in the playroom to keep Legos, matchbox cars, stuffed animals, and other small toys off the floor and in plain sight. Or try one in your workroom to keep all of your craft and wrapping supplies together.” —Jeffrey Welder</p> <p><strong>Use the empty spaces above too</strong></p> <p>“Under cabinets often end up packed to the gills (and hard to use) or half full of dead space. A simple solution is to use half shelves or stackable containers to use as much of the vertical area as you can.” —Schae Lewis and Bahar Partow</p> <p><strong>Make it a game</strong></p> <p>“Our clients love the ‘12-12-12 challenge.’ Each week, set a time to find 12 items to throw away, 12 items to donate, and 12 items to be returned to their proper home. It takes just a few minutes and is a fun, easy way to quickly organise 36 things in your house.” —Alison Bradley of the London Cleaning Team</p> <p><strong>Throw a swap party</strong></p> <p>“If you want to declutter without being wasteful, throw a party and invite friends to bring unused or unwanted items to swap. Everyone gets to go home with something new, and if you end up with leftovers, donate them to a local charity.” —Alison Bradley</p> <p><strong>Shop your wardrobe</strong></p> <p>“An easy way to declutter your wardrobe is to hold up each item and ask yourself, ‘Would I buy this again right now?’ If the answer is no, no matter what the reason is, out it goes.” —Hazel Thornton, professional organiser and author of Go with the Flow! The Clutter-Clearing Tool Kit for an Organised Life</p> <p><strong>Question your stuff</strong></p> <p>“For each item you consider bringing into the house, ask yourself three questions: Where is this going to live? Who will take care of it? Can I afford the money, time and energy it will require? If you don’t have a ready answer for any of these, then put it back.” —Hazel Thornton</p> <p><strong>Start at the bottom of the pile and work up</strong></p> <p>“For overwhelming paper piles, take a sheet from the bottom of the pile. The paper at the bottom is likely to be outdated, unneeded, even forgotten about, and no longer useful. That makes it easy to get rid of.” —Claire Tompkins, clutter coach and author of Five Minutes to a Relaxing Bedroom</p> <p><strong>Can you handle the truth?</strong></p> <p>"It’s hard to figure out what’s clutter in your own space because you’re so used to it. You take it for granted. Sometimes you can’t even see it. So pretend you’re showing a nosy visitor around. When she picks up that decorative box and asks you why you have it and if you like it, you may find yourself answering that it was left over from a white elephant sale and actually, no, you don’t even want it. The results can be surprising and liberating.” —Claire Tompkins</p> <p><strong>Keep things where you actually need them</strong></p> <p>“Put garbage or recycling bins where they’ll be used. If rubbish or recycling collect in the bedroom or living room, save yourself a trip and put the bins there, so you don’t have to go searching for them when you need them. Keep your shredder and recycling bin near where you process incoming mail. This allows you to take care of the paper right away rather than letting it pile up.” —Sarah Krivel, owner of Simpler Surroundings, a professional organising and productivity consulting company</p> <p><strong>Cherish the memory with a photo</strong></p> <p>“If you’re keeping something purely for sentimental reasons, take a picture and then give the item away. Recognise it’s the memory you cherish, not the actual item.” —Sarah Krivel</p> <p><strong>Set a limit for decluttering</strong></p> <p>“To avoid getting overwhelmed, I suggest to my clients to set the timer on their phones for a half hour. When the buzzer goes off they can stop! This can also be done by saying you’ll fill one bag to give away and then take a break. Often, just seeing their progress is motivation enough to keep going.” —Felice Cohen, professional organiser</p> <p><strong>Get creative with repurposing old items</strong></p> <p>“Sometimes something doesn’t need to be thrown out; sometimes it just needs to be used in a different way. For instance, use an empty tissue box to hold extra plastic grocery bags inside a kitchen pantry, cabinet, or closet. Or repurpose a bathroom towel rod by placing it on a garage wall to hold skateboards or longboards.” —Nancy Haworth, professional organiser, On Task Organising</p> <p><strong>If you don’t love it or use it, lose it</strong></p> <p>“This seems like a no-brainer, but it’s amazing what we can talk ourselves into keeping. For instance, gifts that we received and now feel obligated to keep forever, clothing that collects dust in our wardrobe but was too expensive to just get rid of, or childhood mementos that are taking over your storage space even though you’ve never taken the time to actually look back on them. If there is something that you are holding on to, be honest with yourself. Do you love it? Do you use it? Your home is a representation of yourself, and it should only be filled with items that you enjoy and use.” —Rachel Rosenthal, professional organiser and owner of Rachel and Company</p> <p><strong>Don’t forget why libraries exist</strong></p> <p>“If you have a large book collection, gather all your books from around the house so you can sort through them all together. Keep the ones you will still read, still reference, or have a particular love of. The rest can be donated. Remember, you can download many books now, and libraries still exist. Once you’ve whittled down your collection, decide how you would like to display your books: by topic, by author, by size, or by colour. Shelve the keepers accordingly. Create sections like a library or bookstore would have (thriller, reference, biography, comedy) or alphabetical by author.” —Amy Trager, certified professional organiser.</p> <p><strong>Organise spices alphabetically</strong></p> <p>“This allows you to quickly find what your recipe calls for, as well as figure out which spices your cabinet is missing. Whether in a drawer, laying flat, or in a cabinet on tiered shelves, alphabetizing will make grabbing spices quick and putting them away just as fast. If you enjoy cooking a lot and a variety of cuisines, you can also organise spices by cuisine type: Indian, Asian, Mediterranean, baking, etc.” —Amy Trager</p> <p><strong>The bye-bye box</strong></p> <p>“Take all supplies off of the top of your desk – pens, sticky notes, paper clips, etc – and put them in a box to the side. As you work, take out only the things you need to use. After two weeks, you’ll know what you actually use, and whatever hasn’t been taken out of the box can be discarded or donated.” —Sara Skillen</p> <p><strong>Save the instructions</strong></p> <p>“It makes sense that the manual for something like a printer, television, or computer should be kept next to or under the item it goes with. Sure, you could file them away, but chances are when you need the manual you will be standing next to the malfunctioning item. So simply slip the instructions underneath, taped to the back, or next to the equipment.” —Lee Silber, author of Organising from the Right Side of the Brain</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/home-tips/42-organising-tips-youll-wish-you-knew-all-along" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

As winter looms, <a href="https://www.aer.gov.au/news-release/default-market-offer-2023%25E2%2580%259324-draft-determination">energy price rises</a> will make it even harder. Cold homes and disconnections resulting from energy poverty threaten people’s health and wellbeing.</p> <p><a href="https://www.acoss.org.au/wp-content/uploads/2023/03/ACOSS-cost-of-living-report2-March-2023_web_FINAL.pdf">Income support for welfare recipients</a> and retrofitting homes to make them more thermally efficient – by adding insulation, for example – can ease the burden. And when homes are not too cold or hot, <a href="https://theconversation.com/fuel-poverty-makes-you-sick-so-why-has-nothing-changed-since-i-was-a-child-living-in-a-cold-home-201787">people’s health benefits</a>. This in turn <a href="https://apo.org.au/node/319556">eases pressure on the public health system</a>.</p> <p>However, many people are missing out on assistance as programs often do not recognise their difficulties. Their energy vulnerability is hidden.</p> <h2>What forms does hidden energy poverty take?</h2> <p><a href="https://www.sciencedirect.com/science/article/pii/S2214629623000737">Our newly published study</a> has revealed six aspects of hidden energy vulnerability. These are:</p> <ol> <li> <p>underconsumption – households limit or turn off cooling, heating and/or lights to avoid disconnections</p> </li> <li> <p>incidental masking – other welfare support, such as rent relief, masks difficulties in paying energy bills</p> </li> <li> <p>some households disguise energy poverty by using public facilities such as showers or pooling money for bills between families</p> </li> <li> <p>some people conceal their hardship due to pride or fear of legal consequences, such as losing custody of children if food cannot be refrigerated because the power has been cut off</p> </li> <li> <p>poor understanding of energy efficiency and the health risks of cold or hot homes adds to the problem</p> </li> <li> <p>eligibility criteria for energy assistance programs may exclude some vulnerable households. For example, people with income just above the welfare threshold are missing out on energy concessions. Energy retailer hardship programs also ignore people who have voluntarily disconnected due to financial hardship.</p> </li> </ol> <h2>5 ways to help these households</h2> <p>Our studies suggest trusted intermediaries such as people working in health, energy and social services can play a vital role in identifying and supporting such households.</p> <p>First, energy efficiency and hardship initiatives may be <a href="https://www.rmit.edu.au/about/schools-colleges/property-construction-and-project-management/research/research-centres-and-groups/sustainable-building-innovation-laboratory/projects/care-at-home-system-improvements">integrated into the My Aged Care in-home care system</a>. Energy poverty risk identification, response and referral could be built into the national service’s assessment form. This could leverage existing client screening processes.</p> <p>The system’s front-line staff could connect at-risk householders with energy counsellors. These counsellors could help people access better energy contracts, concessions, home retrofits and appliance upgrade programs.</p> <p>A new Commonwealth “energy supplement” could help pay for essential energy-related home modifications. This would help avoid My Aged Care funds being diverted from immediate healthcare needs.</p> <p>Second, general practitioners and other health professionals could help identify energy vulnerability among patients with medical conditions of concern. They could also provide letters of support emphasising renters’ health-based need for air conditioners or heaters.</p> <p>Third, energy providers could use household energy data to identify those that seem to be under-consuming or are often disconnected. They could also identify those that are not on “best offer” deals. They could be proactive in checking struggling householders’ eligibility for ongoing energy concessions and one-off debt relief grants offered by states and territories.</p> <p>Energy providers could also make it easier for social housing providers to ensure concessions for tenants renew automatically.</p> <p>Fourth, local councils could use their data to identify at-risk householders. They might include those with a disability parking permit, discounted council rates or in arrears, on the social housing waiting list, Meals on Wheels clients and social housing tenants. Maternal and child health nurses and home and community care workers making home visits could call attention to cold or hot homes.</p> <p>Councils could employ in-house energy counsellors to provide assistance and energy literacy training. Council home maintenance teams could develop bulk-buying, insulation and neighbourhood retrofit programs.</p> <p>Strategies to reduce vulnerability to energy poverty should be part of municipal public health and wellbeing plans. Under these strategies, net-zero-carbon funds set up by states and local councils to reduce emissions could finance targeted housing retrofits.</p> <p>We also suggest setting up a central helpline to improve access to energy assistance via local referrals.</p> <p>Fifth, residential energy-efficiency programs could become more person-centric. For example, we already have <a href="https://www.homescorecard.gov.au/">Residential Efficiency Scorecard</a> audits to assess the thermal quality of a home. These audits could also explore whether concessions and better energy deals are available to the household.</p> <h2>Building capacity at all levels</h2> <p><a href="https://cur.org.au/cms/wp-content/uploads/2021/08/tackling-hidden-energy-final.pdf">Capacity-building strategies</a> are needed at all levels – individual, community and government – to overcome the <a href="https://www.sciencedirect.com/science/article/pii/S2214629623000737">challenges</a> of reducing energy poverty. Current obstacles include the competing priorities of service providers, lack of time and resources, and <a href="https://www.sciencedirect.com/science/article/abs/pii/S2214629622003553">poor co-ordination between siloed</a> programs and services.</p> <p>Access to essential energy services should be part of state and local governments’ strategic health plans. Housing, energy and health departments could work together to include housing retrofits in preventive health programs.</p> <p>A comprehensive approach is needed to overcome hidden energy poverty. It must include public education, integrated services and well-funded energy-efficiency programs. Regulatory reforms and ongoing funding are both needed to improve the availability of energy-efficient, affordable homes for tenants.</p> <p>Our suggested strategies start with improving the skills and knowledge of trusted intermediaries. Doctors, social workers, housing officers, community nurses and volunteers can play a central role. Using these front-line professionals to help identify and act on energy poverty offers a novel, cost-effective and targeted solution.</p> <p><em>This article originally appeared on <a href="https://theconversation.com/1-in-4-households-struggle-to-pay-power-bills-here-are-5-ways-to-tackle-hidden-energy-poverty-204672" target="_blank" rel="noopener">The Conversation</a>.</em></p> <p><em>Images: Getty</em></p>

How to set up your room to help you fall asleep

<p>Getting a good night’s rest is essential for your health and quality of life. Sometimes sleep can be disturbed due to coffee or stress but sometimes it can be caused by the state of a bedroom. If you are having trouble falling asleep at night then your bedroom environment might be part of the problem. If your bedroom isn’t the sleep-friendly environment it should be, try these tips today.</p> <p><strong>1. Remove night lights and electronics</strong></p> <p>If you have a bright light shining from a radio or alarm clock, it might be a good idea to cover it at night or turn it around so the light isn’t facing you as you sleep. Our brains can misinterpret dim lights and be aroused to wake up. It is also important to not be on your electronic devices right before you go to sleep due to the light that radiates from the screen.</p> <p><strong>2. Shut your curtains</strong></p> <p>Even though the light from the moon, car headlights or streetlights might be outside your window, they still could be a factor in keeping you up. Drapes will help you fall asleep at night time and stop the morning sun waking you up as well.</p> <p><strong>3. Lower the temperature</strong></p> <p>Just a small drop in temperature can help induce sleep. Experts recommend cooling down your room by a few degrees to aid your brain in drifting asleep peacefully. Studies have also found that wearing socks can help you fall asleep. It is believed that if your feet are warm, it helps the internal body temperature drop.</p> <p><strong>4. Get a comfy mattress</strong></p> <p>A painful mattress will not only disturb your sleep but it will also leave you with aches and pains in the morning. Make sure you shop around and research carefully before buying a mattress so you can get one that allows you to have the most natural and deep sleep. Mattress protectors and mattress toppers are also a worthwhile investment for extra softness and comfort as you sleep.</p> <p><strong>5. Choose the right colour scheme</strong></p> <p>Colours can speak volumes to your subconscious so it is important to paint and decorate your room with calming colours. Colours such as blue, purple and light pink can help calm your thoughts. Select colours that are the right shade to help you feel tranquil before you fall asleep at night.</p> <p><strong>6. Declutter your bedroom</strong></p> <p>The impact of a cluttered room is far greater than you might initially think. If you are tossing and turning in the night make sure that before you go to bed, your bedroom is cleared of unnecessary clutter. Once your bedroom is clean, it will make you feel like you have more space and that you aren’t restricted.</p> <p><strong>7. Choose the right bedding</strong></p> <p>The right sheets, the right pillows and the perfect number of pillows are all factors in helping you fall asleep. Whether you want cotton or flannelette bed sheets, make sure you are maintaining their quality as you use them.</p> <p><em>Image credits: Getty Images</em></p>

How to clean jewellery at home: 14 household items that work miracles

<h2>How to make your jewellery shine</h2> <p>If you want to clean your bling but don’t want to shell out lots of money for a professional, fear not – there are lots of easy methods for how to clean jewellery right at home. You don’t have to save it for your most valuable cocktail rings or necklaces, either. Even the best affordable jewellery needs a cleaning every now and then, especially those delicate earrings that you never take off, even after they turn your skin green.</p> <h2>What is the best home remedy to clean jewellery?</h2> <p>These trusted everyday items are just as good as (if not better than) jewellery cleaner, and you probably already have most of them in the house.</p> <h2>Alka-Seltzer</h2> <p>Drop your dull-looking jewellery in a glass of fizzing Alka-Seltzer for a couple of minutes. It will sparkle and shine when you pull it out.</p> <h2>Aluminium foil</h2> <p>Here’s how to clean jewellery with aluminium foil: simply line a small bowl with it. Fill the bowl with hot water and mix in one tablespoon of bleach-free powdered laundry detergent. Put the jewellery in the solution and let it soak for one minute. Rinse well and air-dry. This procedure makes use of the chemical process known as ion exchange, which can also be used to clean silverware.</p> <h2>Ammonia</h2> <p>Brighten up your gold and silver trinkets by soaking them for ten minutes in a solution of 1/2 cup clear ammonia mixed with 1 cup warm water. Gently wipe clean with a soft cloth and let dry. Note: do not do this with jewellery containing pearls, because it could dull or damage their delicate surface.</p> <h2>Baking soda</h2> <p>To remove built-up tarnish from your silver, make a thick paste with 1/4 cup baking soda and 2 tablespoons water. Apply with a damp sponge and gently rub, rinse, and buff dry. To polish gold jewellery, cover with a light coating of baking soda, pour a bit of vinegar over it, and rinse clean. Note: do not use this technique with jewellery containing pearls or gemstones, as it could damage their finish or loosen any glue.</p> <h2>Light-coloured beer</h2> <p>Get the shine back in your solid gold rings (read: bands without any gemstones) and other jewellery by pouring a bit of light-coloured beer (not dark ale!) onto a soft cloth and rubbing it gently over the piece. Use a clean second cloth or towel to dry.</p> <h2>Soda water</h2> <p>Soak your diamonds, rubies, sapphires, and emeralds in club soda to give them a bright sheen. Simply place them in a glass full of soda water and let them soak overnight.</p> <h2>Denture tablets</h2> <p>Has your diamond ring lost its sparkle? Here’s how to clean jewellery using denture tablets: drop the tablet into a glass along with 1 cup water. Follow that with your ring or diamond earrings. Let it sit for a few minutes. Remove your jewellery and rinse to reveal the old sparkle and shine.</p> <h2>Ketchup</h2> <p>Let ketchup do the work of shining tarnished silver. If your ring, bracelet, or earring has a smooth surface, dunk it in a small bowl of ketchup for a few minutes. If it has a tooled or detailed surface, use an old toothbrush to work ketchup into the crevices. To avoid damaging the silver, don’t leave the ketchup on any longer than necessary. Rinse your jewellery clean, dry it, and it’s ready to wear.</p> <h2>Toothpaste</h2> <p>Put a little toothpaste on an old toothbrush and use it to make your diamond ring sparkle instead of your teeth. Clean off the residue with a damp cloth.</p> <h2>Vinegar</h2> <p>Is vinegar good for cleaning jewellery? Yes! Here’s how to clean jewellery with it: soak your pure silver bracelets, rings, and other jewellery in a mixture of 1/2 cup white vinegar and 2 tablespoons baking soda for two to three hours. Rinse them under cold water and dry thoroughly with a soft cloth.</p> <p> </p> <div> </div> <p> </p> <h2>Vodka</h2> <p>In a pinch, a few drops of vodka will clean any kind of glass or jewellery with crystalline gemstones. So although people might give you strange looks, you could dip a napkin into your vodka on the rocks to wipe away the grime on your eyeglasses or dunk your diamond ring for a few minutes to get it sparkling again. But don’t try this with contact lenses! Also, avoid getting alcohol on any gemstone that’s not a crystal. Only diamonds, emeralds and the like will benefit from a vodka bath.</p> <h2>Window cleaner</h2> <p>Use window cleaner to spruce up jewellery that is all metal or has crystalline gemstones such as diamonds or rubies. Spray on the cleaner, then use an old toothbrush for cleaning. But don’t do this if the piece has opaque stones such as opal or turquoise, or organic gems such as coral or pearl. The ammonia and detergents in the cleaner can discolour these porous lovelies.</p> <h2>Dish soap</h2> <p>Dish soap can do a whole lot more than just clean your kitchen! It’s great for regular jewellery cleaning. All you need to do is mix a few drops of dish soap with warm water and let the jewellery soak in the solution for a few minutes. You can use this method for silver jewellery too, but you’re better off using a toothbrush or cloth to wipe down that jewellery rather than fully submerging it. Don’t forget to rinse!</p> <h2>Shampoo</h2> <p>A bit of mild shampoo – think baby shampoo – is a great way to polish your pearls. Stones like turquoise and opals will benefit from this treatment as well. To use this method most effectively, mix a little bit of shampoo with warm water and use a soft, clean brush like a makeup brush to polish each pearl with the mixture. You don’t want to risk damaging pearls by soaking them.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/diy-tips/how-to-clean-jewellery-at-home-14-household-items-that-work-miracles?pages=2" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

7 deadly sins that lead to hoarding

<p>If you’ve watched <em>Enough Already!</em> on <em>Oprah</em> with equal parts sympathy and fear, thinking to yourself “That better not be me one day”, then you’ll want to read on. Non-hoarders tend to picture hoarders as people who have rooms brimming with old newspapers piled to the roof and hallway cupboards that they can not open for fear of the contents swallowing them up. The word hoarder just sounds dirty. While researchers are still trying to understand the disorder, here are some clues that could signal you need to enlist some help. </p> <p><strong>Every room has a “storage area”</strong> – If your dedicated storage area is so full that you need to keep the extra microwave in the living room, you may have a problem. When your storage overflows into the rest of the home and continues to grow – check yourself.
</p> <p><strong>Keeping old magazines and newspapers</strong> – Do you hold on magazines and newspapers thinking, “I might like to reread that one day…” Stop it! Just get rid of them. Apart from coffee table-worthy magazines, everything should be thrown out. Besides a lot of stuff is now online.
</p> <p><strong>Storing clothes you don’t wear</strong> – While it’s ok to hold onto your favourite band T-shirt from your younger years, holding onto old clothes – especially those that don’t fit or have holes in them – it just plain silly. Donate all items that fall into this category to charity immediately!</p> <p><strong>Stowing away broken electronics and appliances</strong> – Don’t kid yourself, you’re never go to get around to fixing that printer or TV! Recycle or donate used electronic items that you no longer use.</p> <p><strong>Storing free loot (aka junk)</strong> – Yes, yes we’ve all fallen victim to being giddy with excitement over a free key ring or pen we pocketed at a show or the RTA. But just because you got a free mug doesn’t mean it should be stashed in your drawer or kitchen never to see the light of day again. Chuck it!</p> <p><strong>Your car becomes “extra” storage</strong> – If you keep more than just spare tire and pair of shoes in your car boot, then you are hoarder territory. If you need to keep DVDs and camping gear in the car because they wont fit in the house, it’s time for drop-off to the Salvos. </p> <p><strong>Daily life becomes musical chairs</strong> – If there is no where to sit and eat dinner because every chair is piled high with papers and you can’t sleep comfortably because the bed is covered in clothes, seek help immediately!</p> <p><em>Image credits: Shutterstock</em></p>

6 secrets from people with peaceful homes

<p>Does your home feel at times a bit chaotic? Try these top tips to re-instil serenity into your life at home.</p> <p><strong>1. Add plants</strong> – Plants will bring a necessary life to your room while maintaining the peaceful environment.</p> <p><strong>2. Use water colours</strong> – Light shades of certain colours can have a calming effect, including blues and greens. Try to avoid the use of any very bright shades, as these can stimulate the mind.</p> <p><strong>3. Decrease clutter</strong> – If your room is in disarray, your mind will be too. Get rid of excess clutter, i.e. anything that you haven’t used in the last 6 months (unless it’s seasonal) to make your room visually calmer.</p> <p><strong>4. Get some fish</strong> – Aquariums are a great way to add both life and serenity to a room. The sound of running water has a tranquil effect on the environment while the fish themselves are incredibly relaxing to watch as they swim about.</p> <p><strong>5. Add cosy elements</strong> – Add soft fabrics and textures such as a cashmere throw to your couch or bed for a look and feel that’s comfortable.</p> <p><strong>6. Assess the windows</strong> – If you live in a quiet area, open the windows to let in a pleasant breeze and remove any distracting odours while bringing in peaceful sunlight. If you live in a busy city environment, give the windows a close while leaving the curtains open to re-instil serenity to your environment.</p> <p><em>Image credits: Getty Images</em></p>

Renovating your home could ruin your relationship… but it doesn’t have to

<p>Many <a href="https://www.cbc.ca/news/canada/toronto/covid-home-renovations-1.5856136">Canadians have turned to home renovations</a> to find space — both literally and metaphorically — after a year of working, learning, exercising and doing just about everything else from home. As we head into spring and summer, the most popular seasons for home improvement, it’s important for couples to set ground rules before breaking ground.</p> <p>While more living space, a dedicated home office or upgraded kitchen might ease the strain the pandemic has put on homes and families, the renovation process, which <a href="https://www.psychologytoday.com/ca/blog/life-after-50/201811/renovation-and-couples-conflict">tests relationships at the best of times</a>, could put more stress on partnerships already cracking under the weight of the past year.</p> <p>Contractors and architects say the recent surge in renovation work has them fielding up to five times as many calls per day than they were pre-pandemic. And according to a recent <a href="https://abacusdata.ca/home-renovations-covid-19/">Abacus Data survey</a>, 44 per cent of Canadian households have done or are planning to do renovations this year. Most say they are doing the work so they can feel more relaxed in their homes.</p> <p>At the same time, <a href="https://www.cbc.ca/news/canada/ottawa/couples-counselling-covid19-1.5557110">phones are also ringing at couples counselling and family law offices</a> as more seek professional help to either preserve or dissolve their relationships.</p> <p>“Couples are experiencing a whole variety of stresses — childcare, household management, personal challenges, strains in the relationship — and the temperature has gone up during the pandemic,” says <a href="https://tribecatherapy.com/">New York City therapist Matt Lundquist</a>. He believes that while the stresses of the pandemic may not be the cause of marriage problems, they are revealing cracks that were already there. </p> <h2>Relationship cracks on full display</h2> <p>Renovations can widen relationship cracks as couples find themselves navigating financial stresses, extended disruptions and making thousands of decisions — from how much they can afford to spend to lower a basement to selecting drawer pulls for new kitchen cabinets. </p> <p>The process can amplify conflicting approaches to <a href="https://doi.org/10.9790/1684-1305064448">decision-making, unhealthy communication habits and latent tensions in relationships</a>.</p> <p>These strains are on display on <a href="https://www.reddit.com/r/relationship_advice/">Reddit’s r/relationship_advice</a>where desperate users seek advice for resolving renovation conflicts with their partners.</p> <p>From “I’m an <a href="https://www.16personalities.com/intp-personality">INTP</a>, he’s an <a href="https://www.16personalities.com/entj-personality">ENTJ</a>, we’re renovating and fighting so badly I fear our relationship will never recover” to “renovation taking way longer than expected, BF taking it personally when I try to speed the process along. We’re at a breaking point” and “renovation frustration with me (29f) and him (31m) — is this understandable or abuse?”</p> <p>Gloria Apostolu, principal architect at <a href="https://www.postarchitecture.com/">Post Architecture</a> in Toronto, pauses for a moment when asked how couples handle the demands of making so many decisions during a renovation. “Every client has their Achilles heel,” she says. “And it’s never where or what I expected.”</p> <h2>Different breaking points</h2> <p>Some of Apostolu’s clients can’t make sense of tiles. Others balk at the price of a front door or are overwhelmed by having to settle on a faucet type for the main-floor powder room all before the contractor even arrives to tear the place apart. </p> <p>Making high-stakes decisions as a couple, Lundquist explains, requires advanced skills, such as weighing pros and cons, gauging the level of acceptable risk and being decisive under pressure, or “pulling the trigger” in contractor parlance. It also requires what he calls relationality — listening and curiosity, taking turns, empathy and working to understand your partner’s point of view, even if you don’t see its logic or agree with it.</p> <p>“It tremendously taxes our skills not to react when our partner says something we disagree with, or isn’t what we expected,” says Lundquist. What really feeds a relationship, he adds, is trying to be curious about where your partner is coming from and resisting the temptation to shut them down or make a counter-argument before fully understanding their point of view.</p> <p>On the other hand, he often encounters partners who, in trying to keep the peace, are <a href="https://www.quickanddirtytips.com/health-fitness/mental-health/let-go-resentment">not assertive enough about what they want, which can lead to lingering dissatisfaction and resentment</a>. </p> <p>The last thing a relationship needs, Lundquist jokes, is a big, expensive, fixed piece of resentment that a couple is forced to stare at as they sit next to each other on the couch every evening.</p> <h2>Honesty and a smooth renovation</h2> <p>Apostolou echoes the need for openness as a foundation for a smooth renovation. </p> <p>She suggests devising a system at the start for resolving the inevitable conflicts that will arise. This could mean taking turns, or giving veto rights to the person who is most dedicated to that part of the home. For example, the person who does most of the cooking gets the final say on kitchen details. </p> <p>She advises it is most important to work it all out in drawings before you get started. “Don’t rush the design process. You don’t want to be making decisions that are more costly than they would have been if they were planned out in advance.” </p> <p>Apostolu’s no-surprises approach has garnered <a href="https://www.houzz.com/professionals/architects-and-building-designers/post-architecture-inc-pfvwus-pf%7E847407266">effusive five-star reviews</a> from clients on home design and improvement website Houzz.</p> <p>One is from Stephanie Nickson, a financial services consultant, and her partner David Raniga, who now runs his massage therapy practice in the light-filled basement of their recently renovated home in Toronto’s Wychwood neighbourhood. </p> <p>Raniga jokes that the hardest part of the process was dealing with his wife’s inability to make decisions. But because they remained open to each other’s needs throughout the process and stuck with the vision and budget they set at the beginning, they say they actually miss the process now that it is over. And they are almost giddy with the result. </p> <p>“I literally say I love this house every day. We were so lucky,” Nickson says.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/renovating-your-home-could-ruin-your-relationship-but-it-doesnt-have-to-157942" target="_blank" rel="noopener">The Conversation</a>. </em></p>

What does the dust in your home mean for your health?

<p>You vacuum it, sweep it and wipe it off your furniture. But do you know what it actually is – and how it may affect your health?</p> <p>Don’t feel bad if you’re clueless about your dust. Scientists are not that far ahead of you in terms of understanding the sources and health risks of indoor air and particles.</p> <p>That’s an issue, because people spend a lot of time indoors. Indeed, the average American stays within four walls for <a href="https://doi.org/10.1038/sj.jea.7500165">almost 90% of their day</a>. So knowing more about how your indoor environment affects your health is vital.</p> <p>To better quantify environmental influences on health, researchers have begun using <a href="https://doi.org/10.1093/ije/dyr236">an “exposome” approach</a>, which considers every last environmental exposure an individual experiences over a lifetime. Your own exposome includes everything from secondhand smoke when you were a baby to lead exposure in your childhood to particulate matter if you grew up near a major roadway or industrial facility.</p> <p>Dust is a big component of the exposome. What particles are you inhaling and ingesting as you go about your day?</p> <p>I'm a geochemist, and my lab studies environmental health at the household level. Along with environmental scientist <a href="https://scholar.google.com/citations?user=d_ZBfxYAAAAJ&amp;hl=en&amp;oi=ao">Mark Taylor</a> at Macquarie University and other international partners, I’m conducting a research project on the indoor exposome.</p> <p>Instead of dumping their vacuum canister into the trash, citizen-scientists put it into a sealable bag and send it off to our lab for analysis. This project, called <a href="https://www.360dustanalysis.com/">360 Dust Analysis</a>, is one of a number of recent efforts that are starting to crack the code on indoor dust. </p> <h2>The dust is coming from inside</h2> <p>About one-third of household dust is created inside your home. The components differ depending on the construction and age of your home, the climate and the cleaning and smoking habits of occupants, so there’s no standard formula for dust.</p> <p>First, you and your pets generate some of that detritus. Sloughed off human skin cells are part of the debris. So are <a href="https://doi.org/10.1016/j.jaci.2010.05.042">pet skin cells</a>, called dander, and dust mites that feed on skin – both of which are strong human allergens.</p> <p>Overall, you can be sure that <a href="http://content.time.com/time/health/article/0,8599,1966870,00.html">your dust also includes some</a> decomposed insects, food debris (especially in the kitchen), fibers from carpet, bedding and clothes, and particulate matter from smoking and cooking. We hope our 360 Dust Analysis program will help solve more of the riddle of just what else goes into dust.</p> <p>So far, so gross. And there are humanmade chemicals in the mix as well. For decades, manufacturers have chemically treated clothing and furniture with flame retardants and surface protectants. In fact, for some time, the <a href="https://www.cpsc.gov/Business--Manufacturing/Business-Education/Business-Guidance/Childrens-Sleepwear-Regulations">flame retardants were required by law</a> in furniture and children’s sleepwear.</p> <p>But then researchers started identifying them in human blood and tissue, and even newborns showed <a href="https://doi.org/10.1021/acs.est.5b01793">evidence of exposure in utero</a>. How did these molecules end up in people’s bodies? Mostly via inhalation or ingestion of indoor dust. </p> <h2>Health concerns about what we put in our homes</h2> <p>Here’s one place new science and new techniques are starting to raise serious health red flags. A flurry of research is currently underway to <a href="https://doi.org/10.1038/s41370-018-0113-2">determine the potential toxicity</a> of these chemicals in the human system. Scientists are also developing new techniques <a href="https://doi.org/10.1038/jes.2017.9">using wearables</a>, such as <a href="https://greensciencepolicy.org/monitoring-chemicals-in-our-environment-with-wristbands/">silicone wrist bands</a>, to determine the relationship between these dust sources and how much of them winds up in a person’s body.</p> <p>A pet-free and fiber-free indoor environment would be one way to reduce the amount and potential toxicity of indoor dust. But there’s an additional concern that’s emerged from recent research: the rise of antimicrobial resistance. </p> <p>Research has linked several indoor disinfection products to antimicrobial resistance. At least one study found that elevated levels of triclosan, a common antimicrobial agent in hand soaps, were correlated with high levels of <a href="https://doi.org/10.1021/acs.est.6b00262">antibiotic-resistant genes in dust</a>, presumably from bacteria that live in your home and dust. This relationship is due to repeated partial, but not complete, destruction of bacteria and other microbes that go on to grow and proliferate, carrying resistant genes.</p> <h2>The dust that comes in from outside</h2> <p>To get a full picture of dust sources and hazards, you need to consider the other two-thirds of the indoor dust load, which <a href="https://doi.org/10.1021/es9003735">actually come from outside</a>. This dirt and dust is tracked in on shoes and on the feet and fur of pets. It blows in through open windows and doorways and vents. And it <a href="https://doi.org/10.1021/es9003735">ranges in size and composition</a>from gritty silt to irritating pollen to the finest of soil particles.</p> <p>One of the most widespread health issues related to outdoor sources is lead. This potent neurotoxin has <a href="http://doi.org/10.12952/journal.elementa.000059">accumulated to sometimes extremely high levels</a> in soils and dust after a century of emissions from industrial sources, vehicles burning leaded gasoline and degraded lead-based paints. The hazard is particularly great in cities and near mining or other industrial point sources of lead. </p> <p>Lead-contaminated soils, and dust generated from them, are tightly linked to <a href="https://www.jstor.org/stable/24927721">lead poisoning of children</a>. Owing to their active neural development, <a href="https://doi.org/10.1146/annurev.med.55.091902.103653">lead can permanently disable exposed children</a>.</p> <p>In the drive to prevent lead poisoning, scientists have focused on what they call point sources: relatively easily identifiable things like peeling paint and lead water pipes. Soil and dust exposures are less well known.</p> <p>Researchers have recently found correlations between <a href="https://doi.org/10.1021/es303854c">lead in air and blood lead levels in children</a>. Now several lab groups are taking a careful look not just at exposures in outdoor settings but <a href="https://doi.org/10.1021/es9003735">also at how lead may seep into homes</a> and become part of the indoor exposome.</p> <h2>Limit what you can</h2> <p>Much as <a href="https://doi.org/10.1126/science.187.4176.535">Freon in refrigerants and other products</a> caused the <a href="https://doi.org/10.1007/978-1-4939-6710-0_2">degradation of Earth’s protective stratospheric ozone layer</a> and <a href="https://doi.org/10.1016/j.reprotox.2007.07.010">bisphenol A, a plasticizer used in bottles</a> and other consumer products ended up in people’s bodies, there’s concern among scientists that “better living through chemistry” might result in a string of <a href="https://www.ehn.org/chemical-exposures-are-small-doses-harm-2518446452.html">unintended human health consequences</a> in the realm of dust.</p> <p>Taking off outdoor clothing like jackets and adopting a shoeless household policy is one way to reduce indoor exposure to outdoor pollutants. <a href="https://www.ciriscience.org/a_96-Study-Reveals-High-Bacteria-Levels-on-Footwear">Shoe bottoms are gross</a>: 96% of shoes have traces of feces bacteria on their soles, including the antimicrobial resistant C. diff, and over 90% of these bacteria are transferred to floors.

Toxic pollutants can build up inside our homes. Here are 8 ways to reduce the risks

<p>We know everything in our homes gathers dust. What you probably don’t know is whether there are toxic contaminants in your house dust, and where these might come from. </p> <p>Our <a href="https://doi.org/10.1016/j.envres.2022.115173">newly published research</a> found most of the dust inside homes came from outside and contains potentially toxic trace metals such as lead, arsenic and chromium. </p> <p>Worryingly, we found some contaminants can accumulate at higher concentrations inside homes than outside. This happened in homes with certain characteristics: older properties, metal construction materials enriched in zinc, recent renovations and deteriorating paint. </p> <p>Fortunately, you can take some simple steps to reduce your exposure, which we explain later.</p> <h2>What’s in house dust?</h2> <p>Our study explored the connected sources, pathways and potentially harmful exposures to trace metals at homes across Sydney. We collected and analysed 383 samples from nearby road dust (51 samples) and garden soil (166), as well as indoor dust (166).</p> <p>We found the dust in homes comes from a range of sources including outdoor environments and soil, skin, cleaning products, pet hair and cooking particles.<br />Nearly 60% of dust particles inside the homes originated from their immediate outdoor environment – it was <a href="https://theconversation.com/wearing-shoes-in-the-house-is-just-plain-gross-the-verdict-from-scientists-who-study-indoor-contaminants-177542">dirt from outside</a>! Wind, your shoes or your pets can carry in <a href="https://www.sciencedirect.com/science/article/pii/S0160412021002075?via%3Dihub">soil</a> and <a href="https://pubs.acs.org/doi/10.1021/acs.est.1c04494">dust</a>-related contaminants.</p> <p>The remaining 40% of home dust came from indoor sources. These included <a href="https://theconversation.com/microplastics-are-common-in-homes-across-29-countries-new-research-shows-whos-most-at-risk-189051">fibres from clothes, carpets and furnishings</a>, cleaning products, skin and hair.</p> <p>Some dust sources can carry a cocktail of potentially harmful contaminants including:</p> <ul> <li> <p><a href="https://doi.org/10.1016/j.envpol.2021.117064">microplastics</a></p> </li> <li> <p><a href="https://doi.org/10.1016/j.envres.2014.10.009">persistent organic pollutants</a></p> </li> <li> <p><a href="https://doi.org/10.1016/j.scitotenv.2019.05.463">perfluorinated chemicals</a> (PFAS)</p> </li> <li> <p><a href="https://doi.org/10.1016/j.envpol.2021.117593">trace metals</a></p> </li> <li> <p><a href="https://doi.org/10.3389/fenvs.2021.754657">bacterial communities</a></p> </li> <li> <p><a href="https://doi.org/10.1016/j.envint.2021.106501">antimicrobial resistance genes</a>. </p> </li> </ul> <p>The nature of the risk is related to how much of the contaminant you’re exposed to and for how long. The risks are greatest in children under the age of five. This is because they are small, closer to the floor and have frequent hand-mouth contact, which increases ingestion of contaminants.</p> <h2>How do contaminants build up in homes?</h2> <p>Industrial activity has left a marked legacy of contaminants in many city neighbourhoods. We analysed road dust, garden soil and vacuum dust samples from 166 homes in Sydney to see how this risk translated to inside homes. We used high-magnification microscopy and <a href="https://www.climate-policy-watcher.org/earth-sciences/lead-isotopes-as-tools-for-source-identification.html">lead isotopic ratios</a> to understand trace metal composition in the samples. </p> <p>On average, concentrations of trace metals arsenic, chromium, copper, manganese, lead and zinc were all higher inside homes than outside. This means homes are not only “accumulators” of trace metal contaminants but also important sources of a significant proportion of harmful contaminants that we can be exposed to. </p> <p>The lead isotopic ratios, or the lead “fingerprints”, of each home and its garden soil matched. This confirms the soil is the main source of lead inside homes. </p> <p>Most of this lead is the result of the pre-1970s use of high concentrations of lead in <a href="https://www.dcceew.gov.au/environment/protection/chemicals-management/lead/lead-in-house-paint">paints</a> and <a href="http://dx.doi.org/10.1016/j.apgeochem.2017.02.007">petrol</a>, which contaminated many garden soils. Even <a href="https://theconversation.com/why-lead-is-dangerous-and-the-damage-it-does-116506">low levels of lead exposure</a> can be harmful. Lead levels in some <a href="https://theconversation.com/elevated-lead-levels-in-sydney-back-yards-heres-what-you-can-do-68499">Sydney backyards</a> pose a risk for <a href="https://doi.org/10.1016/j.dib.2021.107151">urban veggie growers</a> and <a href="https://theconversation.com/backyard-hens-eggs-contain-40-times-more-lead-on-averagethan-shop-eggs-research-finds-187442">backyard chickens and their eggs</a>.</p> <p>High-magnification images of house dust showed mineral particles that have been blown in or tracked in on shoes. The rest of the dust was elongated fibres and hair from indoor sources.</p> <h2>Which homes are most at risk?</h2> <p>We also collected information about each house, relevant activities and renovations at the property. We found house age, proximity to the city centre and renovations had the greatest influence on levels of lead and other trace metals in the home. </p> <p>All homes more than 50 years old had higher concentrations of arsenic, copper, lead and zinc in their garden soil and house dust. They are typically <a href="https://iupui-earth-science.shinyapps.io/MME_Sydney/">located closer to city centres</a>, where early industrial activity has contaminated soils. </p> <p>As older homes in former industrial areas are renovated, trace metal loads in these homes and gardens can increase. Walls and ceilings contain decades of dust. Old paint buried under more recent layers can also be released, causing <a href="https://www.abc.net.au/radionational/programs/backgroundbriefing/3983094">lead exposure risks</a>. </p> <p>It is critical that home renovators take appropriate remediation steps or <a href="https://painters.edu.au/Training-Courses/CPCCPD3031-Work-safely-with-lead-painted-surfaces-in-the-painting-industry.htm">employ a qualified paint professional</a> so lead dust isn’t spread across the area.</p> <h2>8 ways to reduce your risk</h2> <p>We spend about <a href="https://escholarship.org/uc/item/1zg3q68x#main">70% of our time at home</a>, which the pandemic has increased. Understanding the environmental <a href="https://www.cdc.gov/niosh/topics/exposome/default.html">conditions and contaminants we encounter</a>and their effects on our health is more important than ever. </p> <p>Armed with this knowledge, though, you can take some simple steps to reduce your exposure to contaminants in your home and garden:</p> <ol> <li> <p>regularly vacuum carpeted areas with a good vacuum cleaner fitted with a <a href="https://www2.education.vic.gov.au/pal/ventilation-air-purification/print-all">HEPA filter</a></p> </li> <li> <p>wet mop and wet dust hard surfaces</p> </li> <li> <p>mulch areas of exposed soil in your garden</p> </li> <li> <p>use a quality doormat and wash it regularly, which can roughly <a href="https://nrl.northumbria.ac.uk/id/eprint/51148/1/Manuscript_File_Global_Pb_Modeling_Final_clean_1%20%281%29.pdf">halve the amount of lead</a> in your home within three months</p> </li> <li> <p>leave your shoes at the door as they can <a href="https://theconversation.com/wearing-shoes-in-the-house-is-just-plain-gross-the-verdict-from-scientists-who-study-indoor-contaminants-177542">bring all sorts of nasties into the home</a></p> </li> <li> <p>wash your hands and your veggies thoroughly </p> </li> <li> <p>close windows on windy days</p> </li> <li> <p>when renovating, use dust-mitigation strategies and personal protective equipment (PPE).</p> </li> </ol> <p>You can dig a little deeper into what’s in your own home environment by sending your soil to <a href="https://www.360dustanalysis.com/">VegeSafe Australia</a> or <a href="https://www.epa.vic.gov.au/for-community/get-involved/citizen-science-program/gardensafe">EPA Victoria’s GardenSafe</a> for analysis.

Cate Blanchett hints at early retirement

<p>Cate Blanchett has alluded to an early retirement from acting in a candid interview. </p> <p>The Aussie actress, who is currently based in Los Angeles, is primed for yet another Oscars win for her role in the upcoming psychological drama <em>Tár</em>, but shared that the movie took a major toll.</p> <p>Chatting with <em>The Sunday Project</em>, the 53-year-old said she was still trying to "process" the emotional load of working on the film, in which she plays the fictional world-famous pianist Lydia Tár.</p> <p>“I think it was because it was such a physical role, the echoes of it are still with me and I think I’m like a lot of audience members, I need time to process it,” Blanchett said.</p> <p>“Obviously I’m lucky enough to work with some amazing directors who have changed my life, but when it all comes together like that, it does stay with you."</p> <p>“So I don’t ever want to work again …” she added, laughing.</p> <p>After working in show business for three decades, Blanchett admitted she has been “profoundly homesick over the last four years”, after basing herself in Los Angeles from 2015 alongside husband Andrew Upton and their four children.</p> <p>“‘I’m very obsessed, as most Australians, obsessed by water. I want to be by the water, in the water,” she said.</p> <p>“I would love to learn to be patient, to be still and think. My grandmother was a wonderful gardener and my mother is likewise an excellent gardener and she lives with us, and I really want to spend time in the garden with my mum.”</p> <p>At the end of the interview, <em>The Project</em> co-host Hamish McDonald joked, “Congrats on the film, and your retirement.”</p> <p>Blanchett added, “I’m sure there are millions of people around the world applauding right now.”</p> <p><em>Image credits: Getty Images</em></p>

5 ways to save space at home

<p>Although many of us enjoy a good de-cluttering, a more pressing problem can be finding somewhere to put the items that you decide to keep.</p> <p>Many homes lack the space for things that use to come standard such as linen cupboards and storage cupboards. In a lot of homes, built in wardrobes are seen as an optional extra rather than a must-have. Which means a lot of your treasure doesn’t have a permanent place to reside.</p> <p>Try some of our space saving ideas today, which can help you tidy away the bits and pieces that need a home.</p> <p><strong>Utilise space under the bed</strong></p> <p>Instead of letting dust set up house under there, invest in some plastic tubs that fit under your bed. Fill them with anything from sheets and blankets to shoes and hats.</p> <p><strong>Install a low bookshelf underneath windows</strong></p> <p>The area under a window is often wasted space. A small bookshelf there can hold books, games, photo albums, or even a stereo. Visit a home hardware store and look for DIY shelves.</p> <p><strong>Make your bathroom mirror into a cupboard</strong></p> <p>If you just have a standard mirror fitted, you could be missing out on a great spot to store your toiletries. A bathroom cabinet is not too expensive and means your basin is free of clutter.</p> <p><strong>Use space saver bags to store off-season clothes</strong></p> <p>These nifty little bags shrink clothes right down simply by using a vacuum cleaner to remove the air that takes up valuable space. Available from most discount stores, you can also use them for things like doonas and blankets that can take up lots of room in your linen cupboard.</p> <p><strong>Add a shelf above doorways</strong></p> <p>Another underutilised spot, the area above doors (especially hallways) is perfect for storing things like books or CDs. Check first that the wall is able to support a shelf before you start drilling.</p> <p><em>Image: Getty Images</em></p>

How many of these dirty spots in the home are you guilty of NOT cleaning?

<p>Just when you think you’ve got the house spick and span, along comes a list like this to keep you on your toes.</p> <p><strong>Ceiling fans</strong></p> <p>The tops of these can get dusty and grimy quickly, especially if they are anywhere near the kitchen. Get up there with a hot soapy cloth and give them a good wipe down.</p> <p><strong>TV remote</strong></p> <p>Dirty fingers can leave sticky marks on your remote, which should be cleaned with a slightly damp cloth. If you ever eat in front of the TV you can just imagine how dirty the remote must be.</p> <p><strong>Dustpan and brush</strong></p> <p>The products that clean up the mess need a wash now and then too. A soak in a bucket of hot water and bleach is a great way to clean these. Then allow to dry in the sun.</p> <p><strong>Yoga mat</strong></p> <p>All that Zen-sweat can be a breeding ground for bacteria. Give your yoga mat a clean regularly by taking it in the shower with you and rubbing it with soap or shower gel, then dry on the line. While you’re in the mood, pop your gym bag in the wash too.</p> <p><strong>Cloth bags</strong></p> <p>If you’re toting around your groceries in a cloth bag, little bits of food can start to accumulate in the bottom. Throw them in the washing machine regularly to keep them in good condition.</p> <p><strong>Tops of doors and picture rails</strong></p> <p>What you don’t see can easily be forgotten but the tops of doors and rails can quickly accumulate dust and grime. Get up there with a hot soapy cloth, followed by a buff with a dry clean cloth.</p> <p><strong>Bathroom door handle</strong></p> <p>We don’t need to go into too much detail as to why you need to clean this, but it is important that you do it.</p> <p><strong>Fridge seals and handle</strong></p> <p>The grime that gets in your seals can be easily removed with a hot soapy cloth. Remember to clean the handle regularly too – just think how many times you open the fridge when preparing food (with potentially sticky fingers).</p> <p><strong>Hairbrush</strong></p> <p>All that hair and dead skin accumulates quickly in a brush. Remove any hair and then use hot soapy water to soak your brushes. Allow them to dry in the sun.  </p> <p><strong>Sponges</strong></p> <p>It’s scary to think that the item you use to clean your whole kitchen could be harbouring some serious bacteria. You need to regularly clean your sponges and cloths by soaking them in the sink with a big glug of bleach in hot water.</p> <p><em>Image: Getty Images</em></p>
