To keep your cool in a heatwave, it may help to water your trees

<a href="https://theconversation.com/profiles/gregory-moore-1779">Gregory Moore</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> <a href="https://knowledge.aidr.org.au/resources/heatwave/">Heatwaves</a> are among the world’s <a href="https://wmo.int/topics/heatwave#:%7E:text=Impact,died%20from%20heat%2Drelated%20stress.">deadliest</a> weather hazards. Every year, vast numbers of people are <a href="https://www.sciencedirect.com/science/article/pii/S1462901114000999">killed by heat stress</a> and it can worsen health problems such as <a href="https://www.who.int/news-room/fact-sheets/detail/climate-change-heat-and-health">diabetes, asthma and heart disease</a>. Unfortunately, the bitumen roads, brick and concrete structures and roofing tiles in cities can absorb and retain vast amounts of heat, much of which is released after the sun has set. This creates what’s known as the <a href="https://www.climatechange.environment.nsw.gov.au/impacts-climate-change/built-environment/urban-heat">urban heat island effect</a>. In fact, temperatures can be <a href="https://www.climatechange.environment.nsw.gov.au/impacts-climate-change/built-environment/urban-heat#:%7E:text=and%20rural%20environments.-,In%20large%20cities%2C%20average%20temperatures%20can%20be%201%C2%B0C,parts%20experiencing%20even%20higher%20temperatures.">significantly higher in cities</a> than in <a href="https://greenly.earth/en-us/blog/ecology-news/6-key-things-to-know-about-urban-heat-islands">surrounding or rural areas</a>. Trees and greenspace can <a href="https://wwf.org.au/blogs/trees-lower-temperatures-in-a-sydney-street-by-20-degrees/">drive down urban temperatures</a> – but they must be able to draw water from the soil to achieve these massive cooling effects. In other words, it can sometimes be helpful to water your trees during a heatwave. <h2>How trees keep us cool (and no, it’s not just about shade)</h2> Trees reduce urban temperatures in two significant ways. One is by the shade they provides and the other is through their cooling effect – and no, they’re not the same thing. Water is taken up via a plant’s roots, moves through the stems or trunks and is then misted into the air from the leaves through little holes called stomata. This is called transpiration, and it helps cool the air around leaves. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=615&fit=crop&dpr=1 600w, https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=615&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=615&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=772&fit=crop&dpr=1 754w, https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=772&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/640861/original/file-20250107-15-dfepgd.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=772&fit=crop&dpr=3 2262w" alt="A diagram shows how transpiration happens." /></a><figcaption>Transpiration helps cools the air around a plant’s leaves. <a class="source" href="https://www.shutterstock.com/image-vector/transpiration-stages-plants-roots-absorb-water-1856372440">grayjay/Shutterstock</a></figcaption></figure> Water can also evaporate from soil and other surfaces. The combined loss of water from plants and soil is called evapotranspiration. The cooling effects of evapotranspiration vary but are up to <a href="https://www.sciencedirect.com/science/article/pii/S2095311913605432#:%7E:text=Our%20literature%20review%20suggests%20that,ways%20of%20reducing%20urban%20temperatures">4°C</a>, depending on other environmental factors. <h2>Watering your trees</h2> If heatwaves occur in generally hot, dry weather, then trees will provide shade – but some may struggle with transpiration if the soil is too dry. This can reduce the cooling effect of trees. Keeping soil moist and plants irrigated, however, can change that. The best time to irrigate is early in the morning, as the water is less likely to evaporate quickly before transpiration can occur. You don’t need to do a deep water; most absorbing roots are close to the <a href="https://theconversation.com/here-are-5-practical-ways-trees-can-help-us-survive-climate-change-129753">surface</a>, so a bit of brief irrigation will often do the trick. You could also recycle water from your shower. Using mulch helps trap the water in the soil, giving the roots time to absorb it before it evaporates. All transpiring plants have a cooling effect on the air surrounding them, so you might wonder if trees have anything special to offer in terms of the urban heat island effect and heatwaves. Their great size means that they provide much larger areas of shade than other plants and if they are transpiring then there are greater cooling effects. The surface area of tree leaves, which is crucial to the evaporative cooling that takes place on their surfaces, is also much greater than many other plants. Another advantage is that trees can be very long lived. They <a href="https://www.epa.gov/heatislands/using-trees-and-vegetation-reduce-heat-islands">provide shade, cooling and other benefits</a> over a very long time and at relatively low cost. <h2>Not all trees</h2> All that said, I don’t want to overstate the role of urban trees in heatwaves when soils are dry. Some trees cease transpiring early as soils dry, but <a href="https://auf.isa-arbor.com/content/39/3/109">others will persist</a> until they wilt. Careful tree selection can help <a href="https://treenet.org/resource/it-isnt-rocket-science-street-trees-can-make-a-difference-in-climate-change/">maximise the cooling effects</a> of the urban forest. Trees that suit the local soil and can cope with some drying while maintaining transpiration can provide greater cooling And, of course, it is important to follow any <a href="https://www.water.vic.gov.au/for-households/water-restrictions-and-rules/permanent-water-saving-rules">water restriction</a> <a href="https://www.nsw.gov.au/environment-land-and-water/drought/water-restrictions">rules</a> or <a href="https://www.sydneywater.com.au/water-the-environment/what-we-are-doing/water-wise-guidelines.html">guidelines</a> that may be operating in your area at the time. <h2>Trees keep us cool</h2> Despite the clear benefits trees can provide in curbing heat, tree numbers and canopy cover are declining annually in many Australian cities and towns. Housing development still occurs without proper consideration of how trees and greenspace improve residents’ quality of life. It is not an either/or argument. With proper planning, <a href="https://theconversation.com/adelaide-is-losing-75-000-trees-a-year-tree-removal-laws-must-be-tightened-if-we-want-our-cities-to-be-liveable-and-green-216990">you can have both</a> new housing and good tree canopy cover. We should also be cautious of <a href="https://au.news.yahoo.com/trees-butchered-by-power-company-highlight-common-problem-its-sad-012952515.html?guccounter=1">over-pruning</a> urban trees. Trees cannot eliminate the effects of a heatwave but can mitigate some of them. Anything that we can do to mitigate the urban heat island effect and keep our cities and towns cooler will reduce heat-related illness and associated medical costs.<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/246486/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/gregory-moore-1779">Gregory Moore</a>, Senior Research Associate, School of Agriculture, Food and Ecosystem Sciences, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What are cooling blankets? Can they really help me sleep?

<a href="https://theconversation.com/profiles/linda-grosser-1461631">Linda Grosser</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/luana-main-2270550">Luana Main</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> You wake up exhausted from yet another hot night of tossing and turning, with very little sleep. So you might be tempted to buy a “cooling blanket” after reading rave reviews on social media. Or you might have read online articles with <a href="https://www.news.com.au/checkout/home-and-garden/bedroom/bedding/best-cooling-blankets/news-story/118ce05eba1e7d5cdff3aeadae5ae940">taglines such as</a>: <blockquote> Stop waking up in a puddle of sweat with our roundup of the best cooling blankets – including a top-rated option from Amazon that ‘actually works’. </blockquote> But what are cooling blankets? And can they help you get a restful night? <h2>We know a cooler bedroom is best</h2> First, let’s look at why a cooler environment helps us sleep better at night. Our body’s internal temperature has a <a href="https://www.sleepfoundation.org/circadian-rhythm">circadian rhythm</a>, meaning it fluctuates throughout the day. A couple of hours before bed, it drops about <a href="https://www.sciencedirect.com/science/article/pii/S1087079203000236">0.31°C</a> to help you fall asleep. It will drop about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7323637/">another 2°C</a> across the night to help you stay asleep. During sleep, your internal temperature and skin work together to achieve a balance between losing and producing heat. Your skin has sensors that pick-up changes in the environment around you. If it gets too warm, these sensors let your body know, which may cause you to kick-off blankets or bed clothes and wake more often leading to poorer sleep quality. <a href="https://www.thensf.org/what-is-sleep-quality/">Sleep quality</a> is an important component of sleep health ensuring you get the physical, mental and emotional benefits that come from a good night’s sleep. The <a href="https://www.sciencedirect.com/science/article/pii/S0360132318300325">ideal temperature</a> for sleep varies depending on the season and type of bedding you have but falls between 17°C and 28°C. Keeping your sleeping environment within this range will help you to get the best night’s rest. <h2>So what are cooling blankets?</h2> Cooling blankets are designed to help regulate your body temperature while you sleep. Different technologies and materials are used in their design and construction. We’re not talking about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2206487/">hospital-grade</a> cooling blankets that are used to reduce fever and prevent injury to the nervous system. These use gel pads with circulating water, or air-cooling systems, connected to automatic thermostats to monitor someone’s temperature. Instead, the type of consumer-grade cooling blankets you might see advertised use a blend of lightweight, breathable materials that draw moisture away from the skin to help you stay cool and dry through the night. They look like regular blankets. Common materials include cotton, bamboo, silk or the fibre <a href="https://goodonyou.eco/how-ethical-is-tencel/">Lyocell</a>, all of which absorb moisture. Manufacturers typically use a <a href="https://www.sleepfoundation.org/best-sheets/best-thread-count-for-sheets">thread count</a> of <a href="https://www.trustsleep.com/how-do-cooling-blankets-work/">300-500</a>, creating air pockets that enhance airflow and moisture evaporation. Some blankets feature a <a href="https://getrest.com.au/blogs/all/unveiling-the-secrets-of-q-max-the-key-to-a-perfect-nights-sleep">Q-Max rating</a>, which indicates how cool the fabric feels against your skin. The higher the value, the cooler the fabric feels. Others feature <a href="https://www.trustsleep.com/how-do-cooling-blankets-work/">phase change materials</a>. These materials were developed by <a href="https://spinoff.nasa.gov/Spinoff2009/ch_4.html">NASA</a> for space suits to keep astronauts comfortable during a spacewalk where temperatures are from roughly <a href="https://www.nasa.gov/humans-in-space/spacewalk-spacesuit-basics/">-157°C to 121°C</a>. Phase change materials in cooling blankets absorb and hold heat producing a cooling effect. <h2>Do they work?</h2> If you believe online reviews, yes, cooling blankets can cool you down and help you sleep better in warmer weather or if you get too hot using normal sheets and blankets. However, there is little scientific research to see if these consumer-grade products work. In a 2021 <a href="https://www.mdpi.com/2071-1050/13/16/9099">study</a> exploring sleep quality, 20 participants slept for three nights under two different conditions. First, they slept with regular bed sheets in an air-conditioned room with the temperature set to their preference. Then, they used cooling bed sheets in an air-conditioned room where the temperature was set 3°C higher than their preference. Participants reported good sleep quality in both conditions but preferred the warmer room with its cooling sheets. This may suggest the use of cooling bedding may help provide a more comfortable night’s sleep. But everyone’s cooling needs varies depending on things like age, health, body temperature, the space you sleep in, and personal preferences. So while these products may work for some people who may be motivated to leave a good review, they may not necessarily work for you. <h2>Are they worth it?</h2> There’s a wide variety of cooling blankets available at different prices to suit various budgets. Positive customer reviews might encourage a purchase, especially for individuals experiencing disrupted sleep at night due to heat. Yet, these cooling blankets have limited scientific research to show they work and to say if they’re worth it. So it’s up to you. <h2>What else can I do if I’m a hot sleeper?</h2> If a cooling blanket isn’t for you, there are other things you can do to stay cool at night, such as: <ul> <li> using air conditioning or a fan </li> <li> placing a damp towel under or over you </li> <li> wearing lightweight or minimal sleepwear and avoiding thick or synthetic fabrics, such as nylon, that can trap heat </li> <li> if you usually share a bed, on hot nights, consider sleeping by yourself to avoid excess body heat from your partner. </li> </ul> On a final note, if you often struggle with hot, disturbed sleep, you can check in with your health-care provider. They can see if there is a medical explanation for your disturbed sleep and advise what to try next.<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/244158/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/linda-grosser-1461631">Linda Grosser</a>, Research Associate, Behaviour-Brain-Body Research Centre, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/luana-main-2270550">Luana Main</a>, Associate Professor in Applied Sport Science, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Can you get sunburnt or UV skin damage through car or home windows?

<a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> When you’re in a car, train or bus, do you choose a seat to avoid being in the sun or do you like the sunny side? You can definitely feel the sun’s heat through a window. But can you get sunburn or skin damage when in your car or inside with the windows closed? Let’s look at how much UV (ultraviolet) radiation passes through different types of glass, how tinting can help block UV, and whether we need sunscreen when driving or indoors. <h2>What’s the difference between UVA and UVB?</h2> Of the <a href="https://www.who.int/news-room/questions-and-answers/item/radiation-ultraviolet-(uv)#:%7E:text=Most%20solar%20UVB%20is%20filtered,for%20the%20immediate%20tanning%20effect.">total UV</a> radiation that reaches Earth, about 95% is UVA and 5% is UVB. UVB only reaches the <a href="https://theconversation.com/curious-kids-why-dont-burns-bleed-130792">upper layers</a> of our skin but <a href="https://theconversation.com/what-is-the-uv-index-an-expert-explains-what-it-means-and-how-its-calculated-173146">is the major cause</a> of sunburn, cataracts and skin cancer. UVA <a href="https://theconversation.com/sunscreen-why-wearing-it-even-in-winter-could-be-a-good-idea-219640">penetrates deeper</a> into our skin and causes cell damage that leads to skin cancer. <figure class="align-center "><img src="https://images.theconversation.com/files/646357/original/file-20250203-17-c897dp.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/646357/original/file-20250203-17-c897dp.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=416&fit=crop&dpr=1 600w, https://images.theconversation.com/files/646357/original/file-20250203-17-c897dp.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=416&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/646357/original/file-20250203-17-c897dp.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=416&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/646357/original/file-20250203-17-c897dp.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=523&fit=crop&dpr=1 754w, https://images.theconversation.com/files/646357/original/file-20250203-17-c897dp.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=523&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/646357/original/file-20250203-17-c897dp.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=523&fit=crop&dpr=3 2262w" alt="Graphic showing UVA and UVB penetrating skin" /><figcaption>UVA penetrates deeper than UVB. <a class="source" href="https://www.shutterstock.com/image-vector/difference-radiation-types-sunlight-which-harmful-669925423">Shutterstock/solar22</a></figcaption></figure> <h2>Glass blocks UVA and UVB radiation differently</h2> All <a href="https://onlinelibrary.wiley.com/doi/10.1111/phpp.12022">glass</a> used in house, office and car windows completely blocks UVB from passing through. But only laminated glass can completely block UVA. UVA <a href="https://www.skincancer.org/blog/sneaky-ways-youre-being-exposed-to-the-suns-uv-rays/#:%7E:text=UVB%20rays%2C%20the%20primary%20sunburn,the%20rays%20will%20reach%20you">can pass through</a> other glass used in car, house and office windows and <a href="https://theconversation.com/sunscreen-why-wearing-it-even-in-winter-could-be-a-good-idea-219640">cause skin damage</a>, increasing the risk of cancer. <h2>Car windscreens block UVA, but the side and rear windows don’t</h2> A car’s front windscreen lets in lots of sunshine and light. Luckily it <a href="https://onlinelibrary.wiley.com/doi/10.1111/phpp.12022">blocks 98% of UVA radiation</a> because it is made of two layers of laminated glass. But the side and rear car windows are made of tempered glass, which doesn’t completely block UVA. A <a href="https://jamanetwork.com/journals/jamaophthalmology/fullarticle/2522190">study of 29 cars</a> found a range from 4% to almost 56% of UVA passed through the side and rear windows. The UVA protection was not related to the car’s age or cost, but to <a href="https://www.sciencedirect.com/science/article/pii/S0190962205046244?casa_token=qxVQnQ_mFjEAAAAA:5n6QVYBb22gfsWNLxfxbNtsibJ1JXl_C7RtRhsaQLFVkRocFgoWiI4BnNyMGO35EnyIsLNhFK90">the type</a> of glass, its colour and whether it has been tinted or coated in a protective film. Grey or bronze coloured glass, and window tinting, all increase UVA protection. <a href="https://academic.oup.com/tropej/article/59/6/496/1660803">Window tinting</a> blocks around 95% of UVA radiation. In a separate study from Saudi Arabia, researchers fitted drivers with a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9797294/">wearable radiation monitor</a>. They found drivers were exposed to UV index ratings up to 3.5. (In Australia, sun protection <a href="https://www.cancer.org.au/cancer-information/causes-and-prevention/sun-safety/about-sunscreen/spf50-sunscreen">is generally recommended</a> when the UV index is 3 or above – at this level it takes pale skin about 20 minutes to burn.) So if you have your windows tinted, you should not have to wear sunscreen in the car. But without tinted windows, you can accumulate skin damage. <h2>UV exposure while driving increases skin cancer risk</h2> Many people spend a lot of time in the car – for work, commuting, holiday travel and general transport. Repeated UVA radiation exposure through car side windows might go unnoticed, but it can affect our skin. Indeed, skin cancer is more common on the driver’s side of the body. A <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3117975/">study in the United States</a> (where drivers sit on the left side) found more skin cancers on the left than the right side for the face, scalp, arm and leg, including 20 times more for the arm. <a href="https://pubmed.ncbi.nlm.nih.gov/20226568/">Another US study</a> found this effect was higher in men. For <a href="https://www.cancerresearchuk.org/about-cancer/melanoma/stages-types/melanoma-in-situ-stage-0#:%7E:text=What%20is%20melanoma%20in%20situ,grown%20deeper%20into%20the%20skin.">melanoma in situ</a>, an early form of melanoma, 74% of these cancers were on the on the left versus 26% on the right. Earlier Australian studies reported more <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC1340770/">skin damage</a> and more <a href="https://jamanetwork.com/journals/jamadermatology/fullarticle/555250">skin cancer</a> on the right side. Cataracts and other eye damage are also <a href="https://www.aoa.org/news/clinical-eye-care/diseases-and-conditions/cataracts-and-uv-exposure-in-driver-side-windows?sso=y">more common on the driver’s side</a> of the body. <h2>What about UV exposure through home or office windows?</h2> We see UV damage from sunlight through our home windows in faded materials, furniture or plastics. Most glass used in residential windows lets a lot of UVA pass through, <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1600-0781.2009.00434.x">between 45 and 75%</a>. Single-pane glass lets through the most UVA, while thicker, tinted or coated glass blocks more UVA. The best options are laminated glass, or double-glazed, tinted windows that allow less than 1% of UVA through. <a href="https://onlinelibrary.wiley.com/doi/10.1111/phpp.12022">Skylights</a> are made from laminated glass, which completely stops UVA from passing through. Most office and commercial window glass has better UVA protection than residential windows, allowing <a href="https://www.sciencedirect.com/science/article/pii/S0190962205046244?casa_token=qxVQnQ_mFjEAAAAA:5n6QVYBb22gfsWNLxfxbNtsibJ1JXl_C7RtRhsaQLFVkRocFgoWiI4BnNyMGO35EnyIsLNhFK90#bib17">less than 25% of UVA transmission</a>. These windows are usually double-glazed and tinted, with reflective properties or UV-absorbent chemicals. Some <a href="https://theconversation.com/smart-windows-could-be-the-next-big-thing-in-renewable-heating-245053">smart windows</a> that reduce heat using chemical treatments to darken the glass can also block UVA. <h2>So when should you wear sunscreen and sunglasses?</h2> The biggest risk with skin damage while driving is having the windows down or your arm out the window in direct sun. Even untinted windows will reduce UVA exposure to some extent, so it’s better to have the <a href="https://theconversation.com/i-cant-get-sunburnt-through-glass-shade-or-in-water-right-5-common-sunburn-myths-busted-150640">car window up</a>. For home windows, <a href="https://onlinelibrary.wiley.com/doi/10.1111/phpp.12022">window films or tint</a> can increase UVA protection of single pane glass. UVA blocking by glass is similar to protection by sunscreen. When you need to use sunscreen <a href="https://onlinelibrary.wiley.com/doi/pdf/10.5694/j.1326-5377.2006.tb00267.x">depends on</a> your skin type, latitude and time of the year. In a car without tinted windows, you could burn after one hour in the middle of the day in summer, and two hours in the middle of a winter’s day. But in the middle of the day next to a home window that allows more UVA to pass through, it <a href="https://onlinelibrary.wiley.com/doi/pdf/10.5694/j.1326-5377.2006.tb00267.x">could</a> take only 30 minutes to burn in summer and one hour in winter.

From securing pets to building ‘insect hotels’ – here are 7 ways to attract birds to your garden

<a href="https://theconversation.com/profiles/rochelle-steven-22148">Rochelle Steven</a>, <a href="https://theconversation.com/institutions/murdoch-university-746">Murdoch University</a> and <a href="https://theconversation.com/profiles/david-newsome-117672">David Newsome</a>, <a href="https://theconversation.com/institutions/murdoch-university-746">Murdoch University</a> Home gardens can provide vital habitat for Australian birds. But there’s more to it than just planting certain types of shrubs and flowering trees. After decades of encouragement to include native plants in home gardens, urban environments have come to <a href="https://www.sciencedirect.com/science/article/pii/S2351989423003700">favour certain species</a> and <a href="https://doi.org/10.1111/j.1442-9993.2006.01584.x">neglect others</a> including some of our most loved birds, such as fairy-wrens. Birds that thrive on nectar such as honeyeaters, and bossy birds with bold personalities such as noisy miners, some parrots and magpies, tend to dominate the scene. But it doesn’t have to be this way. We wanted to explore how urban gardens can best support a wider range of Australian birds. <a href="https://link.springer.com/article/10.1007/s10531-025-03011-2">Our new review</a> of research on this topic revealed seven key considerations. These fall into two themes: reducing threats and improving habitat. We found there’s no point doing just the good things (such as plantings) if we don’t stop doing the bad things (such as killing insects, poisoning owls and letting cats hunt). It’s like trying to fill a bucket with a hole in it. So let’s acknowledge the complexity of nature and take a broader approach to attracting birds to our gardens, by ticking off the items on this shopping list. <h2>1. Secure pets</h2> Domestic cats kill <a href="https://www.publish.csiro.au/wr/pdf/WR19174">millions of Australian birds every year</a>. So no matter how innocent your cat looks, it remains a highly evolved predator. The only guaranteed way to protect birds and other wildlife from cats is to keep them contained inside or in purpose-built enclosures, 24 hours a day. You can find out about building your own cat enclosure from <a href="https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/cats/enclosures-and-fencing/building-a-cat-enclosure-attached-to-an-existing-structure">government</a> and <a href="https://catiospaces.com/catios-cat-enclosures/cat-behavior-enrichment/build-diy-catio-plan-for-your-cat/">retail</a> experts online. Dogs can also stop birds taking up residence in your garden. The mere <a href="https://doi.org/10.1016/j.landurbplan.2013.10.005">presence of a dog can deter some birds</a>. Keeping dogs contained at night can reduce the level of disturbance to nocturnal birds. But if you really want to attract birds to your garden, you may choose to keep your dog inside more. <h2>2. Avoid using insecticides and outside lights</h2> Many flying and ground-dwelling insects are <a href="https://doi.org/10.1073/pnas.2002549117">in decline</a>. This is bad news for many birds including fairy-wrens, willie wagtails, fantails and robins who rely almost entirely on insects for food. But we can avoid using insecticides or any other form of lethal control such as bug zappers in our own gardens. Ideally, accept insects as a natural part of your garden. Don’t try to deter them, unless they pose a risk to public safety, such as swarming European honeybees or hordes of European wasps. You can also consider favouring native plants that naturally are resisitant to unwanted insect attack. Excess artificial light is also taking a toll on insects. Consider whether you really need to leave that outdoor light on all night. Review your existing outdoor lighting using the <a href="https://darksky.org/resources/guides-and-how-tos/lighting-principles/">five principles for responsible outdoor lighting</a>, ensuring all artificial light is useful, targeted, low-level, controlled and warm-coloured. <h2>3. Stop poisoning raptors</h2> The use of rat poison, especially those labelled as “fast action”, is <a href="https://theconversation.com/rat-poison-is-killing-our-beloved-native-owls-and-tawny-frogmouths-and-thats-the-tip-of-the-iceberg-212184">killing native owls</a> and other <a href="https://doi.org/10.1016/j.scitotenv.2021.147673">birds of prey</a> at an alarming rate due to <a href="https://doi.org/10.1016/j.scitotenv.2018.06.207">secondary poisoning</a>. In other words, raptors are dying after eating rats and mice that have taken the bait. Many countries have regulated the sale and use of these products for this reason, but Australia is lagging behind. So if you “give a hoot” about our owls, <a href="https://kb.rspca.org.au/knowledge-base/what-is-the-most-humane-way-to-kill-pest-rats-and-mice/">switch to snap traps</a>. There are also various other effective, humane and efficient <a href="https://theconversation.com/how-to-control-invasive-rats-and-mice-at-home-without-harming-native-wildlife-180792">options</a> available, including removing unwanted fruit from the ground, keeping sheds tidy, and securing compost bins to keep rodents under control. <h2>4. Prevent window strikes</h2> Birds can fly into windows when they’re unable to differentiate between the glass and the surrounding environment. Strikes may be lethal upon impact or result in injury. A stunned bird is also more vulnerable to predators. In Australia, bird lovers can <a href="https://birdlife.org.au/preventing-bird-strike/#:%7E:text=Why%20do%20birds%20collide%20with,help%20solve%20this%20problem%20too.">reduce the risk</a> by using <a href="https://store.birdlife.org.au/product/anti-collision-bird-stickers/">decals</a> which are decorative stickers intended <a href="https://www.sureguard.com.au/page/birds-eye-view-window-strike-deflector">for windows</a>. Screens, hanging plants or mobiles can also be placed in front of windows to help the birds avoid collisions. <h2>5. Create an inclusive garden</h2> The diversity in Australian birds extends to their diets. Beyond honeyeaters, the nation is home to huge numbers of insectivores, carnivores, seed-eaters and fruit peckers. Australian gardens typically have plenty of bottlebrush and grevilleas, which <a href="https://doi.org/10.1016/j.biocon.2004.06.004">stacks the deck in the bold honeyeaters’ favour</a>. So when buying new garden plants, try catering for a wider variety of bird species. Choose dense shrubs with small white, yellow or blue flowers to attract insects. These bushy plants also make excellent habitat for small birds. Retaining trees ensures our larger birds have nesting sites too. If you get the garden design right, with a variety of plants to suit all tastes, there is <a href="https://birdlife.org.au/a-guide-to-feeding-wild-birds-in-australia/?srsltid=AfmBOooHbf9Du1CarsSg044tVUVFxfBdopOwrOmELrQWcCSdwfKv432v">no need to feed the birds</a>. <h2>6. Encourage insects</h2> <a href="https://www.abc.net.au/news/2024-11-09/blue-banded-bee-australian-insect-of-the-year-inaugral-vote/104572938">Native bees</a> and flies play a crucial role in ecosystems, both as pollinators and food for birds. You can provide insects with nesting habitat in the form of insect “hotels”, food (namely flowers and other insects) and safety from pesticides. These <a href="https://doi.org/10.1016/j.biocon.2015.05.003">small gestures can make a huge difference</a>. <h2>7. Water the birds too</h2> With the <a href="https://climatekids.nasa.gov/heat-islands/">urban heat island</a> effect and growing frequency of extreme heat waves, birds are in need of reliable sources of fresh water. Offer this <a href="https://link.springer.com/article/10.1007/s11252-024-01530-4">crucial resource</a> in a water feature such as a bird bath or pond. <h2>Whole neighbourhoods for birds</h2> Your garden has never been more important for birds. Doing your bit in your own backyard can make a visible difference – you will see the birds for yourself. But true conservation gains can only be made when people work together at a larger scale. Why not start a conversation with your neighbour about attracting birds to your garden? Creating one garden for birds is great, but when we start talking about whole neighbourhoods for birds, that’s magic!<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/247561/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/rochelle-steven-22148">Rochelle Steven</a>, Lecturer in Environmental Management, <a href="https://theconversation.com/institutions/murdoch-university-746">Murdoch University</a> and <a href="https://theconversation.com/profiles/david-newsome-117672">David Newsome</a>, Assoc.

Home ownership is slipping out of reach. It’s time to rethink our fear of ‘forever renting’

<a href="https://theconversation.com/profiles/dorina-pojani-413644">Dorina Pojani</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> A wide range of voices in the Australian media have been <a href="https://www.theguardian.com/australia-news/2024/dec/05/share-with-parents-or-rent-forever-i-have-put-life-on-hold-while-trying-to-buy-a-house">sounding the alarm</a> about the phenomenon of “forever-renting”. This describes a situation in which individuals or families are <a href="https://www.abc.net.au/news/2024-08-10/young-people-priced-out-of-home-ownership/104202602">unable to transition</a> from renting to home ownership, due to rising property values and wages that can’t keep up. Forever-renting is often framed as a terrible condition that should be avoided at all costs – that renting is only acceptable in the short term, as an individual or family saves for a down-payment. The underlying implication is that the ultimate goal in life for just about every Australian should be to own a house – or at least a condominium unit. This only serves to stigmatise renters, who currently make up <a href="https://www.abs.gov.au/statistics/people/housing/housing-occupancy-and-costs/2019-20">nearly a third</a> of Australian households. Demographic research indicates <a href="https://www.jstor.org/stable/24639395">about 15% of Australia’s population</a> changes address every year. Many of these moves require rental accommodation. And, yes, millions of Australians will <a href="https://www.ahuri.edu.au/analysis/news/rising-proportion-forever-renters-requires-tax-and-policy-re-think">rent for their whole life</a>. Clearly, we need to change our thinking around renting to bring it into step with reality. We must accept that the proportion of renters may never go down – or may even increase – and that that’s not necessarily a bad thing. <h2>Where did this attitude come from?</h2> The Australian tradition of home ownership was established in the early decades of European settlement. To make what we now call the “Australian dream” happen, the continent had to be treated as a tabula rasa, or blank slate. A mass of Indigenous people were <a href="https://theconversation.com/refugees-in-their-own-land-how-indigenous-people-are-still-homeless-in-modern-australia-55183">dispossessed</a>. Migration to Australia offered impoverished Britons an opportunity to own a house and plenty of land. In the old country, in contrast, real estate ownership had been a privilege of the gentry. Postwar waves of immigrants from southern Europe and East Asia were also intent on home ownership. In a low-density nation with smallish cities and cheap land, owning a home made sense. Now, urban land is no longer cheap and our <a href="https://www.apimagazine.com.au/news/article/scale-of-urban-sprawl-in-australia-hurting-more-than-just-the-environment">cities have sprawled</a> beyond what’s sustainable. <h2>Renting can have advantages</h2> The first step towards rethinking renting as a norm is acknowledging it can have some significant and often overlooked advantages. For some, renting is a <a href="https://www.emerald.com/insight/content/doi/10.1108/09604521011027598/full/html">lifestyle preference</a>. Ownership comes with burdens such as house and garden maintenance. This makes renting much more convenient and carefree for some demographics, including young people and older adults. Another key advantage of renting is the <a href="https://www.google.com.au/books/edition/Homeownership_and_the_Labour_Market_in_E/GwoUDAAAQBAJ">employment flexibility</a> it can provide. Renters can look for work outside their commute range and are less tied to particular employers. There’s some evidence that high levels of home ownership could even damage the overall labour market. Previous <a href="https://www.nber.org/papers/w19079">research</a> by the US National Bureau of Economic Research has shown that increasing home ownership leads to less labour mobility, longer commutes, and fewer new businesses because homeowners are less likely to move. <h2>Safe as houses?</h2> One common argument against renting is that investing in your own home is a “safe bet”. But we perhaps need to rethink this unquestioned reliance on housing as a store of wealth. Those who enter the housing market for investment purposes should be aware of several issues. Over the long term, housing prices have historically shown a <a href="https://www.dpn.com.au/articles/house-price-growth-australia-over-30-years">general upward trajectory</a>, driven by population growth and limited land supply in desirable areas. In the short term, however, housing prices can be <a href="https://press.uchicago.edu/ucp/books/book/chicago/H/bo20832545.html">quite volatile</a>. They may move up, down, or stay the same. This depends on broader economic cycles, market conditions and interest rates. Think of the housing bubble in the United States, which led to a global recession in 2008, or the <a href="https://www.abc.net.au/news/2025-01-07/china-property-crash-a-warning-for-australian-housing-market/104788660">current downturn in China</a>. The cycles in property prices are often worsened by <a href="https://www.jstor.org/stable/1914185">psychological biases</a> that can lead to overoptimism during booms or panic during busts. Investors may win or lose. <h2>Compounded by climate change</h2> In the contemporary era, we also need to factor in climate change. Areas that are currently desirable may become unappealing before too long – due to <a href="https://www.climatecouncil.org.au/resources/how-hot-will-your-neighbourhood-be-by-2050/">heatwaves</a>, <a href="https://theconversation.com/one-of-the-most-extreme-disasters-in-colonial-australian-history-climate-scientists-on-the-floods-and-our-future-risk-178153">floods</a> or <a href="https://theconversation.com/la-is-on-fire-how-will-australia-cope-when-bushfires-hit-sydney-melbourne-or-another-major-city-246967">fires</a>. Natural disasters, or even just growing disaster risks, can prompt large drops in property prices and massive population movements. To illustrate: during the pandemic, South East Queensland began to draw many domestic migrants as other states struggled to contain the virus. People from cooler southern states were also attracted by the region’s mild winter climate. In 2024, Brisbane became Australia’s <a href="https://www.realestate.com.au/news/uneven-price-growth-reshuffles-rankings-of-australias-most-expensive-cities/">second-most expensive</a> city for property values. That might appear to bode well for property buyers who’ve invested millions of dollars. But one <a href="https://rmets.onlinelibrary.wiley.com/doi/abs/10.1002/joc.5998">2019 study</a> has predicted that temperature rises could make Brisbane “<a href="https://www.abc.net.au/news/2019-06-22/temperature-increases-from-climate-change-brisbane-unliveable/11227404">unbearably hot</a>” by 2050. In this context, renters may be more adaptable than owners. <h2>A more renter-friendly Australia</h2> None of this is to argue that everyone should be a renter, or that renters should be left to the whims of the market. In Australia, current rent increases are <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/consumer-price-index-australia/latest-release">outpacing</a> both wage growth and inflation (CPI). The rental affordability crisis has driven a <a href="https://homelessnessaustralia.org.au/rough-sleeping-surges-as-homelessness-crisis-worsens-new-report/">recent surge</a> in homelessness. There is a wide range of policy tools available to us, many of which have been shown to <a href="https://www.abc.net.au/news/2024-10-16/build-to-rent-fix-housing-crisis-australia-us-uk-hong-kong/104458458">work relatively well in other countries</a> and could be adopted here. These include: <ul> <li> <a href="https://thefifthestate.com.au/housing-2/the-case-for-rent-control-and-historical-norms-in-rent-increases/">rent caps</a>, which tie allowable rent increases to the CPI (Australia already <a href="https://treasury.gov.au/sites/default/files/2019-03/round5-5.pdf">regulates the price of utilities</a> in this way) </li> <li> nationwide no-ground eviction bans (already in place in <a href="https://www.choice.com.au/money/property/renting/articles/no-grounds-evictions-update">some states</a>) </li> <li> normalisation of <a href="https://www.abc.net.au/news/2021-06-28/how-to-find-a-long-term-rental-home/100217074">long-term leases</a> beyond 12 months and restrictions on <a href="https://cities-today.com/barcelona-set-to-ban-short-term-rentals/">short-term rentals such as Airbnb</a> </li> </ul> More vulnerable renters, including people with disabilities, single parents, victims of domestic abuse, those on low incomes, and older retirees, need extra protections. The supply of rental units should also be increased, through <a href="https://www.ahuri.edu.au/analysis/brief/what-build-rent">build-to-rent</a> and <a href="https://www.statedevelopment.qld.gov.au/news-and-events/granny-flats-provide-housing-choice-in-tight-rental-market">granny flat</a> construction, for example. Landlords should not be vilified either. In an unregulated market, they are often cast as “<a href="https://www.realestate.com.au/news/robber-barons-great-landlord-myth-exposed/">robber barons</a>” and “<a href="https://www.theguardian.com/commentisfree/2018/apr/16/landlords-social-parasites-last-people-should-be-honouring-buy-to-let">social parasites</a>”. If tenants were protected from excessive rent increases and evictions, landlordism could also be recast as an essential service that yields reasonable profits to providers.<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/245848/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dorina-pojani-413644">Dorina Pojani</a>, Associate Professor in Urban Planning, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

There’s a link between walking speed and ageing well. Here’s how you can improve your pace

<a href="https://theconversation.com/profiles/andres-rafales-perucha-1528635">Andrés Ráfales Perucha</a>, <a href="https://theconversation.com/institutions/universidad-san-jorge-5704">Universidad San Jorge</a> and <a href="https://theconversation.com/profiles/pablo-gargallo-aguaron-1528652">Pablo Gargallo Aguarón</a>, <a href="https://theconversation.com/institutions/universidad-san-jorge-5704">Universidad San Jorge</a> For decades, we have known that the way you walk, in particular your walking speed, is tied to your health. One study has even proposed that it be considered <a href="https://pubmed.ncbi.nlm.nih.gov/24812254/">a vital sign</a>, much like heart rate and blood pressure. <a href="https://pubmed.ncbi.nlm.nih.gov/26861693/">Various studies</a> have found a link between low walking speed in adults over 65 and a greater risk of cognitive impairment, cardiovascular disease, falls (which could lead to fractures), hospitalisation, and even an increased overall mortality rate. A higher walking speed, on the other hand, is associated with increased functional capacity, meaning a better ability to move around and do activities independently. It is also linked to <a href="https://www.thelancet.com/journals/lanhl/article/PIIS2666-7568(24)00092-8/fulltext">greater longevity</a>. But how fast should you walk? <a href="https://www.sciencedirect.com/science/article/abs/pii/S1568163714000646?dgcid=api_sd_search-api-endpoint">Studies</a> recommend a few simple tests, which principally consist of timing how long it takes a person to walk between two points at their usual pace. This <a href="https://www.physio-pedia.com/4_Metre_Walk_Test">test</a> is done over a distance of four metres. A speed of under 0.8 metres per second is associated with a greater risk of frailty. <h2>How to improve walking speed</h2> While there is slight disagreement as to the best exercise for increasing walking speed, the pattern that seems most effective is <a href="https://pubmed.ncbi.nlm.nih.gov/34409961/">multicomponent training</a>, which includes several different forms of exercise: <ol> <li> Balance exercises can help improve stability and prevent falls. Examples include walking in a straight line putting one foot in front of the other, or standing on one leg, alternating every 10-15 seconds. </li> <li> Flexibility exercises can improve mobility and reduce risk of injury. The benefits of movement in alleviating back pain are <a href="https://theconversation.com/back-pain-why-exercise-can-provide-relief-and-how-to-do-it-safely-162888">well documented</a>. </li> <li> Muscular exercises help build strength in the legs, buttocks and other body areas. These can be as straightforward as standing up and sitting down in a chair. </li> <li> Aerobic exercise improves stamina, and can include walking itself, or <a href="https://theconversation.com/seven-reasons-nordic-walking-is-better-for-you-than-the-normal-kind-187391">Nordic walking</a> (with hiking poles). </li> </ol> <h2>How much aerobic exercise do we need?</h2> The main <a href="https://www.who.int/publications/i/item/9789240014886">guides</a> on physical activity recommend that, provided they are physically and medically able, each adult should do at least 150 minutes of moderately intense aeoribic exercise per week. “Moderate” means you are not too out of breath to hold a conversation, but enough to notice an increased heart and breathing rate. There are few reasons not to do this kind of exercise, and it is beneficial for people with chronic illnesses, including cardiovascular issues, metabolic conditions, or even cancer. <h2>Muscle strength: How, and how much?</h2> Strengthening exercises have traditionally been recommended 2 to 3 times a week, with at least one set per exercise session of the main muscle groups: legs, buttocks, pectorals, back and arms. However, more recent studies suggest that doing less intense but more frequent strengthening exercises may be an effective way to <a href="https://pubmed.ncbi.nlm.nih.gov/34822137/">maintain muscle mass and strength</a>. This would mean doing them almost every day, including even small exercise “snacks” throughout the day. <h2>Use it or lose it</h2> If we don’t train them, muscle mass and strength decrease over time. This not only affects our mobility, but also increases the risk of health problems and even death. A little daily exercise can make a big difference. We therefore recommend that you try to maintain your physical condition as much as possible, both to improve your immediate health and prevent future problems. If you do not know where to start, the best option is always to consult a professional.

Bunnings shopper transforms Christmas decor for just $5

A Bunnings shopper has shared an amazing hack for transforming your home into a Christmas wonderland on a budget. With the help of one item for just $5, an interior designer named Cheryl - who shares home decorating tips on Instagram - transformed her entry hallway in a unique festive way. Cheryl revealed to Yahoo Lifestyle how she created the incredible look for under $100 from Bunnings. Cheryl's stunning space came to life with some $5 renter-friendly hooks from Bunnings, some solar-powered fairy lights and some baubles. Sticking the hooks on the ceiling, she threaded the fairy lights through, zigzagging them down the hall, and then hung baubles from the lights. <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/DDCFN4GSGxs/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/DDCFN4GSGxs/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by ▪︎ Cheryl ▪︎ (@ourcountrycoastalhome)</a> </div> </blockquote> Describing the set-up, Cheryl told Yahoo it's "very easy" and you don't need DIY experience to pull off the festive decor. "All you need are some little hooks that stick onto your ceiling, some wire string lights and some colourful baubles. We got everything we needed for this from Bunnings," she says. She also shared some hot tips for people looking to try out the hack for themselves, jokingly telling us, "All you need is a patient husband to do it for you! Just kidding... the best tip I have is to measure the overall length and divide it by the number of hooks you have and you also want the string lights to go diagonal from one another. What also looks better is to place the baubles offset from each other." Cheryl added that they chose to use solar-powered lights to save money on energy use as well, saying, "To help on power bills we went with solar string lights and just placed the little solar boxes in a spot where they would be exposed to sunlight that way it automatically turns on at night and off in the morning." She said, "It’s a really easy little Xmas DIY and I hope other families will get to enjoy it, it looks amazing at night." Image credits: Instagram

Many people don’t measure their blood pressure properly at home – here’s how to get accurate readings

<a href="https://theconversation.com/profiles/niamh-chapman-2262829">Niamh Chapman</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dean-picone-2264237">Dean Picone</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/eleanor-clapham-2264235">Eleanor Clapham</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Measuring your blood pressure at home means you can take readings over several days to get a better picture of your health, instead of one-off measurements at the doctor’s clinic. It’s important you follow specific steps to get an accurate reading. But <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.124.23678">our study</a> found most Australians do not measure their blood pressure correctly at home and very few were told the steps to follow. We have created <a href="https://bloodpressuretoolkit.com/">resources</a> to help people measure their blood pressure at home, understand their readings and take action with their health-care team. <h2>High blood pressure is a big issue</h2> High blood pressure is a major health problem in Australia and globally. <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.51350">One in three Australian adults</a> have high blood pressure, also called hypertension. This is when your <a href="https://www.heartfoundation.org.au/your-heart/blood-pressure-and-your-heart">blood pressure</a> is <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.120.15026">at or above 140/90mmHg</a> (mmHg refers to millimetres of mercury, a standard measurement of blood pressure). High blood pressure is the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10881002/">leading contributor</a> to preventable health issues and early death among Australians because it is the main risk factor for heart disease, stroke, dementia and kidney disease. <h2>Why measuring blood pressure is important</h2> High blood pressure often has no symptoms. So the only way to know if you have it is to measure it. You may also need to check if your blood pressure has lowered after starting medication or if you’re making changes to your lifestyle, such as doing more exercise, giving up smoking or reducing salt intake. Low blood pressure (<a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/blood-pressure-low-hypotension">hypotension</a>) can also be an issue. But blood pressure changes based on how we are feeling, what we’ve eaten or the activities we have just been doing. These normal responses mean our blood pressure can change from minute to minute and hour to hour. This is why there are specific, recommended steps to follow to reliably measure your blood pressure and to be able to compare readings taken days, months and years apart. <hr /> <iframe id="lBVm6" class="tc-infographic-datawrapper" style="border: 0px none currentcolor;" src="https://datawrapper.dwcdn.net/lBVm6/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>Mistakes are common</h2> We surveyed and interviewed 350 people (who were all measuring their blood pressure at home) from around Australia to find out how Australians measure blood pressure at home and if they receive any education to help them know what to do. Our study found no one followed all of the specific, recommended steps to measure their blood pressure. Instead they said they measured their blood pressure at different times of the day after doing different things. We found most people measured their blood pressure while sitting down (90%) and with the cuff on their bare arm (77%), which is the right thing to do. While 58% of people took two blood pressure measures each time, which is correct, only 40% used the average of the two blood pressure readings. Very few (15%) measured their blood pressure over several days in both the morning and evening. Only half of the people in our study used a blood pressure device that had been <a href="https://bloodpressuretoolkit.com/what_device_should_i_use">clinically validated</a>. This means the device has been <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.117.10237">tested for accuracy</a> by the manufacturer according to <a href="https://www.iso.org/sectors/health">international standards</a>, not just safety. <h2>Consultation and communication</h2> Regardless of whether or not a doctor had recommended they measure their blood pressure at home, most people (78%) reported their blood pressure readings to their doctor. These findings tell us doctors often use home blood pressure readings to help diagnose and manage high blood pressure. This emphasises how important it is to ensure people measure blood pressure correctly. Many people were measuring their blood pressure a few times a week or month. But most <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4671913/">guidelines</a> recommend blood pressure only needs to be measured at home: every day over a week, every six months; and ideally before you see your doctor and after you start or change blood pressure medication. Measuring blood pressure at home can bring peace of mind, which many study participants described. But measuring your blood pressure too often may create unnecessary stress, potentially leading to higher blood pressure readings. Instead, it’s better to agree with your doctor how often you should measure your blood pressure and to follow the recommended steps each time to make sure your readings are as accurate and useful as possible. <h2>Support for blood pressure measurement</h2> We found few people had received any education or guidance from health-care professionals about how to measure their blood pressure at home. Instead, many study participants looked for information online to help them know what their blood pressure numbers meant and changes they could make to lower their blood pressure. They were less interested in learning how to measure accurately. So we have worked with people who measure and manage their blood pressure at home to create a <a href="https://bloodpressuretoolkit.com/">simple guide</a> to help you choose a blood pressure device, measure your blood pressure accurately, understand your blood pressure readings and take action to control your blood pressure. <hr /> For more information about managing your blood pressure at home, <a href="https://bloodpressuretoolkit.com/">see our resources</a>. You can also check if your blood pressure device has been <a href="https://bloodpressuretoolkit.com/what_device_should_i_use">tested for accuracy</a>.<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/244161/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/niamh-chapman-2262829">Niamh Chapman</a>, Senior Research Fellow, Hypertension and Patient Engagement, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dean-picone-2264237">Dean Picone</a>, Senior Research Fellow, Sydney School of Health Sciences, Faculty of Medicine and Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/eleanor-clapham-2264235">Eleanor Clapham</a>, PhD candidate, School of Health and Medicine, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Italian village offers $1 homes to Americans upset by US election results

An Italian village in Sardinia, Italy is offering one-euro homes to Americans seeking a new start following the results of the 2024 U.S election that saw Donald Trump being re-elected as president. Ollolai has long been trying to persuade outsiders to move in to revive the community after decades of depopulation. Now, it's selling dilapidated houses for as little as one euro — just over a US dollar or $AU1.60 — to entice Americans to move abroad. Following the November 5 outcome, they have launched a website aimed at potential American expats, offering cheap homes in hopes that those disappointed by the result and seeking a fresh start will snap up one of their empty properties. "Are you worned (sic) out by global politics? Looking to embrace a more balanced lifestyle while securing new opportunities?" the website read. "It's time to start building your European escape in the stunning paradise of Sardinia." Mayor Francesco Columbu told CNN that the website was specifically created to attract American voters in the wake of the presidential elections. The mayor loves the United States and is convinced Americans would be the best people to revive the community. "We just really want, and will focus on, Americans above all," he said. "We can't of course ban people from other countries to apply, but Americans will have a fast-track procedure. We are betting on them to help us revive the village, they are our winning card." The village is offering three tiers of accommodation: Free temporary homes to certain digital nomads, ($1.6) homes in need of renovations, and ready-to-occupy houses for prices up to $160,000. The mayor also set up a special team to guide interested buyers through every step of the process including finding contractors, builders and navigating required paperwork. "Of course, we can't specifically mention the name of one US president who just got elected, but we all know that he's the one from whom many Americans want to get away from now and leave the country," Columbo added. "We have specifically created this website now to meet US post-elections relocation needs. The first edition of our digital nomad scheme which launched last year was already solely for Americans." Photos and plans of available empty properties will soon be uploaded to the website. The website has since received nearly 38,000 requests for information on houses, with most of them coming from the United States In the past century, Ollolai's population has shrunk from 2,250 to 1,300 with only a handful of babies born each year. Over the last few years, this has dropped 1,150 residents. Image: Shutterstock

What’s the difference between liquid and powder laundry detergent? It’s not just the obvious

<a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> When shopping for a laundry detergent, the array of choices is baffling. All of the products will likely get your laundry somewhat cleaner. But what gets the best outcome for your clothes and your budget? Do you want whiter whites? Do you need enzymes? And what’s the difference between a powder and liquid detergent? As is often the case, knowing more about the chemistry involved will help you answer those questions. <h2>What is a detergent?</h2> The active ingredients in both laundry powders and liquids are “surfactants”, also known as detergents (hence the product name). These are typically charged or “ionic” molecules that have two distinct parts to their structure. One part interacts well with water and the other interacts with oils. This useful property allows surfactants to lift grease and grime from fabrics and suspend it in the water. Surfactants can also form bubbles. Metal salts dissolved in your water can limit the performance of the surfactants. So-called hard water contains lots of dissolved calcium and magnesium salts which can readily form soap scum. Modern laundry detergents therefore contain phosphates, water softeners and other metal “sequestrants” to stop the formation of soap scum. Phosphates can cause algal blooms in fresh water environments. This is why modern detergent formulations <a href="https://accord.asn.au/sustainability/phosphorus-standard/">contain smaller amounts of phosphates</a>. Many products also contain optical brighteners. These chemicals absorb ultraviolet light and release blue light, which provides the “whiter white” or “brighter colour” phenomenon. Laundry detergents typically contain fragrances. These aren’t essential to the chemistry of cleaning, but give the impression the clothes are fresh. Lastly, some laundry detergents contain enzymes – more on those later. <h2>What’s in laundry powder?</h2> While detergents and ingredients to avoid soap scum are the most important components, they aren’t the most abundant. The main ingredients in powders are salts (like sodium sulfate) that add bulk and stop the powder from clumping. Another common salt added to laundry powders is sodium carbonate, also known as washing soda. Washing soda (a chemical cousin of <a href="https://theconversation.com/vinegar-and-baking-soda-a-cleaning-hack-or-just-a-bunch-of-fizz-225177">baking soda</a>) helps to chemically modify grease and grime so they dissolve in water. Laundry powders also frequently contain oxidising agents like sodium percarbonate. This is a stable combination of washing soda and hydrogen peroxide. An additive known as tetraacetylethylenediamine activates the percarbonate to give a mild bleaching effect. Chemically, powders have an advantage – their components can be formulated and mixed but kept separate in a solid form. (You can usually see different types of granules in your laundry powder.) <h2>What’s in laundry liquid?</h2> The main ingredient of laundry liquid is water. The remaining ingredients have to be carefully considered. They must be stable in the bottle and then work together in the wash. These include similar ingredients to the powders, such as alkaline salts, metal sequestrants, water softeners and surfactants. The surfactants in liquid products are often listed as “ionic” (charged) and “non-ionic” (non-charged). Non-ionic surfactants can be liquid by default, which makes them inappropriate for powdered formulations. Non-ionic surfactants are good at suspending oils in water and don’t form soap scum. Liquid detergents also contain preservatives to prevent the growth of microbes spoiling the mixture. There are also microbial implications for inside the washing machine. Liquid products can’t contain the peroxides (mild bleaching agents) found in powdered products. Peroxides kill microbes. The absence of peroxides in liquid detergents makes it more likely for <a href="https://www.mdpi.com/1420-3049/27/1/195#B15-molecules-27-00195">mould biofilms to form</a> in the machine and for bacteria to be transferred between items of clothing. As an alternative to peroxides, liquids will typically contain only optical brighteners. Liquids do have one advantage over powders – they can be added directly to stains prior to placing the item in the wash. A recent “convenience” version of liquid formulas are highly concentrated detergent pods. Colourful and bearing a resemblance to sweet treats, these products have been found to be <a href="https://poisoncenters.org/track/laundry-detergent-packets">dangerous to young children and people with cognitive impairment</a>. Pods also remove the option to add less detergent if you’re running a smaller load or just want to use less detergent in general. <h2>So, what about enzymes?</h2> Enzymes are naturally evolved proteins included in laundry products to remove specific stains. Chemically, they are catalysts – things that speed up chemical reactions. Enzymes are named for the molecules they work on, followed by the ending “-ase”. For example, lipase breaks down fats (lipids), protease breaks down protein, while amylase and mannanase break down starches and sugars. These enzymes are derived from organisms found in cool climate regions, which helps them function at the low temperature of washing water. Running an excessively hot wash cycle can damage or denature the enzyme structure, stopping them from assisting in your wash. Think of an egg white <a href="https://theconversation.com/how-to-make-the-perfect-pavlova-according-to-chemistry-experts-196485">changing from translucent to white while cooked</a> – that’s protein denaturing. If your detergent contains enzymes, the washing temperature should be neither too hot nor too cold. As a guide, temperatures of 15–20°C are used in <a href="https://environment.ec.europa.eu/document/download/557d8ab5-4e75-41a4-a901-1548be7f685d_en">standard laundry tests</a>. <h2>Is powder or liquid better?</h2> We make consumer choices guided by performance, psychology, cost, scent, environmental considerations and convenience. It’s worth experimenting with different products to find what works best for you and fits your needs, household budget and environmental considerations, such as having <a href="https://theconversation.com/curious-kids-why-can-some-plastics-be-recycled-but-others-cant-229270">recyclable packaging</a>. Personally, I wash at 20°C with half the recommended dose of a pleasant-smelling laundry powder, packaged in recyclable cardboard, and containing a wide range of enzymes and an activated peroxide source. Knowing a little chemistry can go a long way to getting your clothes clean. However, laundry detergent manufacturers don’t always disclose the full list of ingredients on their product packaging. If you want more information on what’s in your product, you have to look at the product website. You can also dig a little deeper by reading documents called <a href="https://theconversation.com/a-new-tiktok-trend-has-people-drinking-toxic-borax-an-expert-explains-the-risks-and-how-to-read-product-labels-210278">safety data sheets</a> (SDS). Every product containing potentially hazardous chemicals must have an SDS.<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/239850/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"I’m coming home from a party, and I don’t want to end up getting arrested": do driving apps help people break road rules?

<a href="https://theconversation.com/profiles/verity-truelove-1237331">Verity Truelove</a>, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>; <a href="https://theconversation.com/profiles/michelle-nicolls-1299069">Michelle Nicolls</a>, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>, and <a href="https://theconversation.com/profiles/oscar-oviedo-trespalacios-1417150">Oscar Oviedo-Trespalacios</a>, <a href="https://theconversation.com/institutions/delft-university-of-technology-1040">Delft University of Technology</a> Apps such as Google Maps, Apple Maps and Waze can tell drivers when they are approaching speed cameras or random breath testing stations. Countries such as Germany, France and Switzerland have banned apps from displaying these enforcement locations. But what effect are these apps having in Australia – are they helping drivers break road rules? Our new <a href="https://www.sciencedirect.com/science/article/pii/S0925753524002972">paper</a>, published in the journal Safety Science, examined this question. We found this technology can, in some cases, contribute to people thinking they are invincible on the roads. However, we also found they can sometimes help people drive more safely. <h2>Being made aware of enforcement can help road safety</h2> We conducted focus groups and interviews with a total of 58 drivers from Queensland, to understand how the use of this technology influences perceptions of being caught for breaking road rules. One driver told us: "If I know it’s coming up, I’ll put my phone down. If I was, say, texting or checking something, but then like once a good few 100 metres away, I sort of pick it up again, depending though." Another said: "It sort of depends where I am driving, I guess. Like, if I am driving on a country road and there is a speed camera there I would probably slow down for the speed camera and then sort of speed up again once I am sort of past that; it sort of depends on the circumstances." We also found that, for some people, being made aware of enforcement locations can help drivers better regulate their speed. This helped them comply with road rules more consistently. Waze also shows the speed limit in the area, which further assisted some drivers to stick to the speed limit. One driver told us: "I’m a bit careful if I just look at the speedo and just double check that I’m on the right amount of speed." Another said: "It just gives you a warning like, ‘OK, you need to check your speed.’ Just to double-check you’re going on the right speed perhaps or when it’s a camera coming up." <h2>Concerning behaviours</h2> Concerningly, we also found some drivers who use these apps are looking at and touching their screens more than they otherwise would. This can distract drivers and increase their <a href="https://www.sciencedirect.com/science/article/pii/S0925753524001097">risk of crashing</a>. One driver told us they post traffic updates on the app they use while driving, “which I know is wrong.” Another said: "Just hit the button on the phone. Just two steps after I go past the camera." Another driver told us: "It’s so helpful […] Especially if it’s, say, late night and I’m coming home from a party, and I don’t want to end up getting arrested." One driver said: "I probably feel slightly more invincible, which is probably not a good thing." When asked why these apps are used, one driver said: "I guess the drug and the drink-driving." <h2>Apps can help and hinder road safety</h2> We know breaking road rules significantly contributes to <a href="https://www.who.int/teams/social-determinants-of-health/safety-and-mobility/global-status-report-on-road-safety-2023">crashes and road fatalities</a>, with deaths on Australian roads continuing to <a href="https://www.bitre.gov.au/publications/ongoing/road_deaths_australia_monthly_bulletins">increase</a> over time. On the one hand, when drivers are aware of enforcement measures like cameras and police, they are more likely to stop breaking the rules in those areas. That’s particularly true for behaviours such as speeding and using a phone while driving, we found. Using apps that flag where cameras and police are located also means drivers would be more exposed to enforcement activities than they otherwise would be on a normal drive. On the other hand, our results suggest some drivers are using these applications to break road rules more often in places where they think they won’t be caught. These apps are also not always completely accurate. For instance, even though Waze can display some police operation locations such as roadside breath testing, it can’t capture all on-road police activities. Further, camera locations are not always up to date or accurate. <h2>Weighing benefits against risks</h2> While these apps do have some benefits, it’s important to weigh these against the risks. It’s also important to recognise traffic enforcement isn’t just there to make you comply with road rules at a specific point; it is meant to remind you of the constant risk of being caught and to encourage consistent rule compliance. The goal is to ensure that drivers are following the traffic rules across the entire network, not just in isolated spots. With road fatalities at some of the <a href="https://www.bitre.gov.au/publications/ongoing/road_deaths_australia_monthly_bulletins">highest rates we’ve seen in recent years</a>, we need everyone to work together to stop more preventable deaths and injuries.<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/237664/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/verity-truelove-1237331">Verity Truelove</a>, Senior Research Fellow in Road Safety Research, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>; <a href="https://theconversation.com/profiles/michelle-nicolls-1299069">Michelle Nicolls</a>, PhD Candidate, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a>, and <a href="https://theconversation.com/profiles/oscar-oviedo-trespalacios-1417150">Oscar Oviedo-Trespalacios</a>, A/Professor Responsible Risk Management, <a href="https://theconversation.com/institutions/delft-university-of-technology-1040">Delft University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<a href="https://theconversation.com/profiles/alessandra-sutti-1513345">Alessandra Sutti</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/amol-patil-1513347">Amol Patil</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/maryam-naebe-1513346">Maryam Naebe</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Orbiting 400 kilometres above Earth’s surface, the astronauts on the International Space Station live a pretty normal social life, if not for one thing: they happily wear their unwashed clothes <a href="https://www.nasa.gov/centers-and-facilities/glenn/nasa-glenn-interns-take-space-washing-machine-designs-for-a-spin/">for days and weeks at a time</a>. They can’t do their laundry <a href="https://www.esa.int/Enabling_Support/Space_Engineering_Technology/Keeping_your_underwear_clean_on_the_Moon">just yet</a> because water is scarce up there. But down here on Earth, washing clothes is a large part of our lives. <a href="https://bigee.net/media/filer_public/2013/03/28/bigee_domestic_washing_machines_worldwide_potential_20130328.pdf">It’s estimated</a> that a volume of water equivalent to 21,000 Olympic swimming pools is used every day for domestic laundry worldwide. Fibres from our clothes make their way into the environment via the air (during use or in the dryer), water (washing) and soil (lint rubbish in landfill). Most of this fibre loss is invisible – we often only notice our favourite clothing is “disappearing” when it’s too late. How can you ensure your favourite outfit will outlast your wish to wear it? Simple question, complex answer. <h2>Washing machines are not gentle</h2> When you clean the filters in your washing machine and dryer, how often do you stop to think that the lint you’re holding <a href="https://theconversation.com/uk-laundry-releases-microfibres-weighing-the-equivalent-of-1-500-buses-each-year-199712">was, in fact, your clothes</a>? Laundering is harsh on our clothes, and <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0250346">research confirms this</a>. Several factors play a role: the type of washing machine, the washing cycle, detergents, temperature, time, and the type of fabric and yarn construction. There are two types of domestic washing machines: top-loader and front-loader. Mechanical agitation (the way the machine moves the clothes around) is one of the things that helps ease dirt off the fabric. Top-loaders have a vertical, bucket-like basket with a paddle, which sloshes clothes around in a large volume of water. Front-loaders have a horizontal bucket which rotates, exposing the clothes to a smaller volume of water – it takes advantage of gravity, not paddles. Top-loading machines <a href="https://link.springer.com/article/10.1007/s12541-010-0047-7">tend to be more aggressive</a> towards fabrics than front-loaders due to the different mechanical action and larger volumes of water. Washing machine panels also present many choices. Shorter, low-temperature programs <a href="https://clevercare.info/more-eco-temperature-tips">are usually sufficient for everyday stains</a>. Choose longer or <a href="https://iprefer30.eu/animations/UK/wash-brochure-uk.pdf">high-temperature programs</a> only for clothing you have concerns about (healthcare uniforms, washable nappies, etc.). Generally, washing machine programs are carefully selected combinations of water volume, agitation intensity and temperature recommended by the manufacturer. They take into consideration the type of fabric and its level of cleanliness. Select the wrong program and you can say goodbye to your favourite top. For example, high temperatures or harsh agitation may cause some fibres to weaken and break, causing holes in the garment. <h2>Some fabrics lose fibres more easily than others</h2> At a microscopic level, the fabric in our clothes is made of yarns – individual fibres twisted together. The nature and length of the fibres, the way they are twisted and the way the yarns form the fabric can determine how many fibres will be lost during a wash. In general, if you want to lose fewer fibres, you should wash less frequently, but some fabrics are affected more than others. Open fabric structures (knits) with loose yarns <a href="https://www.nature.com/articles/s41598-021-98836-6">can lose more fibres</a> than tighter ones. Some sports clothing, like running shirts, are made of continuous filament yarn. These fibres are less likely to come loose in the wash. Cotton fibres are only a few centimetres long. Twisted tightly together into a yarn, they can still escape. Wool fibres are also short, but have an additional feature: scales, which make wool clothes much more delicate. Wool fibres can come loose like cotton ones, but also tangle with each other during the wash due to their scales. This last aspect is what causes wool garments to shrink when <a href="https://journals.sagepub.com/doi/abs/10.1177/004051756403400303">exposed to heat</a> and agitation. <h2>Go easy on the chemicals</h2> The type of detergent and other products you use also makes a difference. Detergents contain a soap component, enzymes to make stains easier to remove at low temperature, and fragrances. Some contain harsher compounds, such as bleaching or whitening agents. Modern detergents are very effective at <a href="https://www.choice.com.au/home-and-living/laundry-and-cleaning/laundry-detergents/review-and-compare/laundry-detergents">removing stains such as food</a>, and you don’t need to use much. An incorrect choice of wash cycles, laundry detergent and bleaching additives could cause disaster. Certain products, like bleach, can <a href="https://site.extension.uga.edu/textiles/textile-basics/understand-your-fibers/">damage some fibres like wool and silk</a>. Meanwhile, research on <a href="https://www.sciencedirect.com/science/article/pii/S0269749120366872?via%3Dihub">fabric softeners and other treatments</a> <a href="https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0233332&type=printable">continues</a> – there’s no one-size-fits-all answer about their potential impact on our clothes. <h2>Just skip laundry day</h2> So, how to ensure your clothes last longer? The main tip is to wash them less often. When it’s time for a wash, carefully read and follow the care labels. In the future, our washing machines will <a href="https://www.teknoscienze.com/tks_article/trends-in-laundry-by-2030/">recognise fabrics and select the wash cycle</a>. For now, that’s our responsibility. And the next time you throw your shirt into the dirty laundry basket, stop. Think of the astronauts orbiting above Earth and ask yourself: if they can go without clean laundry for a few days, maybe I can too? (Although we don’t recommend just burning your dirty undies, either.)<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/224064/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <figure><iframe src="https://www.youtube.com/embed/C1j6KLP492E?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <a href="https://theconversation.com/profiles/alessandra-sutti-1513345">Alessandra Sutti</a>, Associate Professor, Institute for Frontier Materials, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/amol-patil-1513347">Amol Patil</a>, Research Engineer, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/maryam-naebe-1513346">Maryam Naebe</a>, Associate professor, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

5 items you’re cleaning too much

Cleaning the house is no easy feat. To make life a little easier for you, here are five items you are probably cleaning more than you need to. 1. Clothes worn once For particular items of clothing such as gym gear, shirts and tights it is fine to wash clothes after every wear. However, most other items can be worn up to three times advises Carolyn Forte, the director of the Cleaning Lab at the Good Housekeeping Institute. "Over-washing and over-drying fabrics can cause fading and wear,” she said. Studies have also shown that it is ideal to wash bath towels after three uses. 2. Dinner plates Instead of spending time rinsing your plates before putting them in the dishwasher, just make sure all the food is scrapped off. "Pre-washing dishes is a waste of time and energy,” said Carolyn. "If you aren't running it right away, let the dishwasher rinse them with a 'rinse only' cycle." 3. Light Fixtures It can be tempting to dust your light fixtures every week but Carolyn advises saving your strength from a different household task. She advises that you can get away with cleaning light fixtures once a month. 4. Jackets In the cooler months jackets are worn every day. However, this necessity only needs to be washed every three months. Jackets don’t usually come into contact with skin cells or natural oils, which allows them to go longer between washes than other clothes. 5. Curtains Curtains need to be washed if you get any marks on them but if they are in pristine condition, according to Carolyn they only need to be cleaned once a year. Image credits: Shutterstock

10 rules every good house guest follows

You've been invited to stay in somebody else's house. You're instantly told "make yourself at home!" But you can't really, can you? Here's the unsaid rules of being a houseguest you just can't break. 1. Not arriving on time Always provide your itinerary to your host before you arrive. If your flight or train is delayed, give them real-time updates. Google Map your journey in advance so you know exactly how to get to their house. It's awfully inconvenient as a host to be waiting to give a guest keys, but have them arrive two hours late because of an excuse like "I got lost". 2. Turning up empty handed You don't need to bring much, but when staying at someone's house you need to arrive with a token of appreciation. A bottle of wine, some chocolates, or a kitsch little jar of jam you made. Turning up empty handed is expected by the host, but all good houseguests know a small gift is the right way to kick things off. 3. Keeping your shoes on Perhaps you live in a shoes-on house when you're at home, but unless told so, you should never keep them on when staying at another's. Especially if you only see your host walking around bare foot, or in socks/slippers. Houseguests bring in extra dirt, fluff, and marks – the most conscious you can be of that, the better. 4. Turning down food When you're staying in somebody else's home, you must eat what you are served. Hosts go to a lot of effort to make you feel welcome and cooking for you is a big part of that. If you have any dietary requirements, say so before you arrive and offer to bring a bag of shopping. Your host will probably refuse, but you've laid the groundwork for happy mealtimes for the duration of your stay. 5. Not cleaning up Picture this: you're staying with a friend, and they're at work all day while you mooch around their house. The dishwasher is full but you don't know where anything goes in the cupboards. You pile your dirties in the sink, and your friend comes home to find them. Cue instant aggression that will forever remain unspoken. Avoid being a bad guest by cleaning up when you're a houseguest – even if you put things back in the wrong place. 6. Not asking to use laundry facilities One of the most difficult things about travelling is getting your laundry done. When a washing machine and dryer become available, it's natural to want to jump on them. But you must ask your host first. They will always say yes – everybody understands what it's like to have to wear inside-out underwear when you've had no laundry facilities for a week – but it's just polite to ask. 7. Asking your host to quiet down When staying in somebody else's house, there's a high chance of noises you're not used to. That could mean your host watching TV at midnight when you've got to be up early, or them talking loudly on the phone at 6AM while you're asleep. But you can't say anything about it. If you are noise-sensitive, always bring quality earplugs. 8. Bringing lovers home We get it, maybe you're in an exciting new city and the options for a little sexy time are pinging at your phone every few minutes. But you cannot, under any circumstances, invite a new lover over to somebody's house when you're staying there. Even if you have their house to yourself, it's just a breach of respect. If you want to hook up, go to their place. 9. Leaving the bed unmade Hosts generally accept there'll be some clean-up after you're gone. But don't leave the guest bed unmade, or your dirty sheets on it. Strip them off on your final morning, and either fold them nicely, or put them in the washing machine (this is one situation where you don't need their permission to use their laundry). Remake the bed with or without clean sheets if possible. 10. Not saying thank you It doesn't have to be a formal written letter (though that would be nice, wouldn't it). But you must thank your hosts after you leave with a note, an e-mail, or even a text. It's something so easy to forget to do once you're gone, but ensures the host feels their hospitality has been appreciated. And if you've not broken any of the other rules, you'll definitely get invited back. Image credits: Shutterstock Written by Lee Suckling.

Why Lisa Marie Presley kept son's body at home for two months after his death

Lisa Marie Presley was so heartbroken by the loss of her only son, Benjamin Keough, at just 27-years-old in 2020, that she kept his body in her home for two months after his death. The star revealed this in her memoir From Here to the Great Unknown, which was finished by her daughter Riley Keough after the 54-year-old’s death in January 2023, according to Page Six. In the book, Lisa Marie opened up about the extent of her grief, saying that she had to force herself to "fight" to stay alive for her remaining children, and one of the ways she coped was not saying goodbye to Benjamin right away. “My house has a separate casitas bedroom and I kept Ben Ben in there for two months. There is no law in the state of California that you have to bury someone immediately,” Lisa Marie wrote. “I found a very empathetic funeral homeowner. I told her that having my dad in the house after he died was incredibly helpful because I could go and spend time with him and talk to him. She said, ‘We’ll bring Ben Ben to you.’” The room was kept at around 12 degrees celsius to preserve his body, and the star continued saying that she felt “fortunate that there was a way that I could still parent him, delay it a bit longer so that I could become okay with laying him to rest.” Another reason why she decided to keep his body was because she wasn't sure whether to bury him in Hawaii or at Graceland, the Memphis estate where Elvis died and is buried. At one point, Riley and Lisa Marie decided to honour Benjamin by getting matching tattoos of his name, which was inscribed in the same place where Benjamin had his tattoos. Riley recalled the odd moment Lisa Marie brought in the tattoo artist into her home. “Lisa Marie Presley had just asked this poor man to look at the body of her dead son, which happened to be right next to us in the casitas. I’ve had an extremely absurd life, but this moment is in the top five," Riley wrote in the memoir. Lisa Marie acknowledged that it was odd, and soon after the tattoo day, they "got the vibe" that Benjamin wanted to be laid to rest. “Even my mum said that she could feel him talking to her, saying ‘This is insane, Mum, what are you doing? What the f**k!” The family held a funeral for Benjamin in Malibu, and he was buried at Graceland alongside Elvis, and now Lisa Marie as well. Image: Copetti/Photofab/ Shutterstock Editorial

How can we improve public health communication for the next pandemic? Tackling distrust and misinformation is key

<a href="https://theconversation.com/profiles/shauna-hurley-203140">Shauna Hurley</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/rebecca-ryan-1522824">Rebecca Ryan</a>, <a href="https://theconversation.com/institutions/la-trobe-university-842">La Trobe University</a> There’s a common thread linking our <a href="https://www.visualcapitalist.com/history-of-pandemics-deadliest/">experience of pandemics</a> over the past 700 years. From the black death in the 14th century to COVID in the 21st, public health authorities have put emergency measures such as isolation and quarantine in place to stop infectious diseases spreading. As we know from COVID, these measures upend lives in an effort to save them. In both the <a href="https://www.thinkglobalhealth.org/article/pandemic-protests-when-unrest-and-instability-go-viral">recent</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3559034/">distant past</a> they’ve also given rise to collective unrest, confusion and resistance. So after all this time, what do we know about the role public health communication plays in helping people understand and adhere to protective measures in a crisis? And more importantly, in an age of misinformation and distrust, how can we improve public health messaging for any future pandemics? Last year, we published a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD015144/full">Cochrane review</a> exploring the global evidence on public health communication during COVID and other infectious disease outbreaks including SARS, MERS, influenza and Ebola. Here’s a snapshot of what we found. <h2>The importance of public trust</h2> A key theme emerging in analysis of the COVID pandemic globally is public trust – or lack thereof – in governments, public institutions and science. Mounting evidence suggests <a href="https://www.washingtonpost.com/world/2022/02/01/trust-lancet-covid-study/">levels of trust in government</a> were <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(22)00172-6/fulltext">directly proportional</a> to fewer COVID infections and higher vaccination rates across the world. It was a crucial factor in people’s willingness to follow public health directives, and is now a key focus for future pandemic preparedness. Here in Australia, public trust in governments and health authorities steadily eroded over time. Initial information from governments and health authorities about the unfolding COVID crisis, personal risk and mandated protective measures was generally clear and consistent across the country. The establishment of the <a href="https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/rp1920/Quick_Guides/AustralianCovid-19ResponseManagement#_Toc38973752">National Cabinet</a> in 2020 signalled a commitment from state, territory and federal governments to consensus-based policy and public health messaging. During this early phase of relative unity, <a href="https://theconversation.com/inflation-covid-inequality-new-report-shows-australias-social-cohesion-is-at-crossroads-195198">Australians reported</a> higher levels of belonging and trust in government. But as the pandemic wore on, public trust and confidence fell on the back of conflicting state-federal pandemic strategies, blame games and the <a href="https://theconversation.com/we-lost-the-plot-on-covid-messaging-now-governments-will-have-to-be-bold-to-get-us-back-on-track-186732">confusing fragmentation</a> of public health messaging. The divergence between <a href="https://www.theaustralian.com.au/nation/tale-of-two-cities-gripped-by-covid-fear-outbreak/news-story/cf1b922610aeb0b0ee9b0b53486bf640">lockdown policies and public health messaging</a> adopted by <a href="https://www.theage.com.au/national/victoria/a-tale-of-two-cities-that-doesn-t-seem-fair-20211012-p58z79.html">Victoria and New South Wales</a> is one example, but there are plenty of others. When state, territory and federal governments have conflicting policies on protective measures, people are easily confused, lose trust and become harder to engage with or persuade. Many tune out from partisan politics. Adherence to mandated public health measures falls. Our research found clarity and consistency of information were key features of effective public health communication throughout the COVID pandemic. We also found public health communication is most effective when authorities work in partnership with different target audiences. In Victoria, the case brought against the state government for the <a href="https://www.abc.net.au/news/2023-07-24/melbourne-public-housing-tower-covid-lockdown-compensation/102640898">snap public housing tower lockdowns</a> is a cautionary tale underscoring how essential considered, tailored and two-way communication is with diverse communities. <h2>Countering misinformation</h2> Misinformation is <a href="https://reutersinstitute.politics.ox.ac.uk/hydroxychloroquine-australia-cautionary-tale-journalists-and-scientists">not a new problem</a>, but has been supercharged by the advent of <a href="https://theconversation.com/health-misinformation-is-rampant-on-social-media-heres-what-it-does-why-it-spreads-and-what-people-can-do-about-it-217059">social media</a>. The much-touted “miracle” drug <a href="https://www.vox.com/future-perfect/22663127/ivermectin-covid-treatments-vaccines-evidence">ivermectin</a> typifies the extraordinary traction unproven treatments gained locally and globally. Ivermectin is an anti-parasitic drug, lacking evidence for viruses like COVID. Australia’s drug regulator was forced to <a href="https://www.theguardian.com/australia-news/2021/sep/10/australian-drug-regulator-bans-ivermectin-as-covid-treatment-after-sharp-rise-in-prescriptions">ban ivermectin presciptions</a> for anything other than its intended use after a <a href="https://www.theguardian.com/world/2021/aug/30/australian-imports-of-ivermectin-increase-10-fold-prompting-warning-from-tga">sharp increase</a> in people seeking the drug sparked national shortages. Hospitals also reported patients <a href="https://www.theguardian.com/australia-news/2021/sep/02/sydney-covid-patient-in-westmead-hospital-after-overdosing-on-ivermectin-and-other-online-cures">overdosing on ivermectin</a> and cocktails of COVID “cures” promoted online. The <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(22)01585-9/fulltext">Lancet Commission</a> on lessons from the COVID pandemic has called for a coordinated international response to countering misinformation. As part of this, it has called for more accessible, accurate information and investment in scientific literacy to protect against misinformation, including that shared across social media platforms. The World Health Organization is developing resources and recommendations for health authorities to address this “<a href="https://www.who.int/health-topics/infodemic#tab=tab_1">infodemic</a>”. National efforts to directly tackle misinformation are vital, in combination with concerted efforts to raise health literacy. The Australian Medical Association has <a href="https://www.ama.com.au/media/action-needed-tackle-health-misinformation-internet-social-media">called on the federal government</a> to invest in long-term online advertising to counter health misinformation and boost health literacy. People of all ages need to be equipped to think critically about who and where their health information comes from. With the rise of AI, this is an increasingly urgent priority. <h2>Looking ahead</h2> Australian health ministers recently <a href="https://www.cdc.gov.au/newsroom/news-and-articles/australian-health-ministers-reaffirm-commitment-australian-cdc">reaffirmed their commitment</a> to the new Australian Centre for Disease Control (CDC). From a science communications perspective, the Australian CDC could provide an independent voice of evidence and consensus-based information. This is exactly what’s needed during a pandemic. But full details about the CDC’s funding and remit have been the subject of <a href="https://www.croakey.org/federal-budget-must-deliver-on-climate-health-and-the-centre-for-disease-control-sector-leaders-warn/">some conjecture</a>. Many of our <a href="https://www.cochraneaustralia.org/articles/covidandcommunications">key findings</a> on effective public health communication during COVID are not new or surprising. They reinforce what we know works from previous disease outbreaks across different places and points in time: tailored, timely, clear, consistent and accurate information. The rapid rise, reach and influence of misinformation and distrust in public authorities bring a new level of complexity to this picture. Countering both must become a central focus of all public health crisis communication, now and in the future.

Is it worth selling my house if I’m going into aged care?

<a href="https://theconversation.com/profiles/colin-zhang-1234147">Colin Zhang</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> For senior Australians who cannot live independently at home, residential aged care can provide accommodation, personal care and general health care. People usually think this is expensive. And many assume they need to sell their home to pay for a lump-sum deposit. But that’s not necessarily the case. Here’s what you need to consider. <h2>You may get some financial support</h2> Fees for residential aged care are complex and can be confusing. Some are for your daily care, some are means-tested, some are for your accommodation and some pay for extras, such as cable TV. But it’s easier to think of these fees as falling into two categories: <ul> <li> an “entry deposit”, which is usually more than <a href="https://www.health.gov.au/sites/default/files/documents/2020/06/eighth-report-on-the-funding-and-financing-of-the-aged-care-industry-july-2020-eighth-report-on-the-funding-and-financing-of-the-aged-care-industry-may-2020.pdf">$A300,000</a>, and is refunded when you leave aged care </li> <li> daily “<a href="https://www.myagedcare.gov.au/aged-care-home-costs-and-fees">ongoing fees</a>”, which are $52.71-$300 a day, or more. These cover the basic daily fee, which everyone pays, and the means-tested care fee. </li> </ul> To find out how much government support you’ll receive for both these categories, you will have a “<a href="https://www.myagedcare.gov.au/income-and-means-assessments/#aged-care-home">means test</a>” to assess your income and assets. This means test is similar (but different) to the means test for the aged pension. Generally speaking, the lower your aged-care means test amount, the more government support you’ll receive for aged care. With full support, you don’t need to pay an “entry deposit”. But you still need to pay the basic daily fee (currently, <a href="https://www.myagedcare.gov.au/aged-care-home-costs-and-fees">$52.71</a> a day), equivalent to 85% of your aged pension. If you get partial support, you pay less for your “entry deposit” and ongoing fees. <h2>You don’t need a lump sum</h2> You don’t have to pay for your “entry deposit” as a lump sum. You can choose to pay a rental-style daily cost instead. This is calculated as follows: you multiply the amount of the required “entry deposit” by the maximum permissible interest rate. This rate is set by government and is currently at <a href="https://www.health.gov.au/sites/default/files/documents/2021/03/schedule-of-fees-and-charges-for-residential-and-home-care-schedule-from-20-march-2021_0.pdf">4.01%</a> per year for new residents. Then you divide that sum by 365 to give a daily rate. This option is like borrowing money to pay for your “entry deposit” via an interest-only loan. You can also pay for your “entry deposit” with a combination of a lump sum and a daily rental cost. As it’s not compulsory to pay a lump sum for your “entry deposit”, you have different options for dealing with your family home. <h2>Option 1: keep your house and rent it out</h2> This allows you to use the rental-style daily cost to finance your “entry deposit”. Pros <ul> <li> you could have more income from rent. This can help pay for the rental-style daily cost and “ongoing fees” of aged care </li> <li> you might have a special sentimental attachment to your family house. So keeping it might be a less confronting option </li> <li> keeping an expensive family house will not heavily impact your residential aged care cost. That’s because any value of your family house above <a href="https://www.health.gov.au/sites/default/files/documents/2021/03/schedule-of-fees-and-charges-for-residential-and-home-care-schedule-from-20-march-2021_0.pdf">$173,075.20</a> will be excluded from your <a href="https://www.servicesaustralia.gov.au/organisations/health-professionals/services/aged-care-entry-requirements-providers/residential-care/residential-aged-care-means-assessment">means test</a> </li> <li> you can still access the capital gains of your house, as house prices rise. </li> </ul> Cons <ul> <li> your rental income needs to be included in the means test for your aged pension. So you might get less aged pension </li> <li> you might need to pay income tax on the rental income </li> <li> compared to the lump sum payment, choosing the rental-style daily cost means you will end up <a href="https://www.smh.com.au/money/super-and-retirement/seek-help-when-weighing-up-how-to-pay-for-your-aged-care-20191202-p53g16.html">paying more</a> </li> <li> you are subject to a changing rental market. </li> </ul> <h2>Option 2: keep your house and rent it out, with a twist</h2> If you have some savings, you can use a combination of a lump sum and daily rental cost to pay for your “entry deposit”. Pros <ul> <li> like option 1, you can keep your house and have a steady income </li> <li> the amount of lump sum deposit will not be counted as an asset in the pension means test. </li> </ul> Cons <ul> <li> like option 1, you could have less pension income, higher age-care costs and need to pay more income tax </li> <li> you have less liquid assets (assets you could quickly sell or access), which could be handy in an emergency. </li> </ul> <h2>Option 3: sell your house</h2> If you sell your house, you can use all or part of the proceeds to pay for your “entry deposit”. Pros <ul> <li> if you have any money left over after selling your house and paying for your “entry deposit”, you can invest the rest </li> <li> as your “entry deposit” is exempt from your aged pension means test, it means more pension income. </li> </ul> Cons <ul> <li>if you have money left over after selling your house, this will be included in the aged-care means test. So you can end up with less financial support for aged care.</li> </ul> <h2>In a nutshell</h2> Keeping your house and renting it out (option 1 or 2) can give you a better income stream, which you can use to cover other living costs. And if you’re not concerned about having access to liquid assets in an emergency, option 2 can be better for you than option 1. But selling your house (option 3) avoids you being exposed to a changing rental market, particularly if the economy is going into recession. It also gives you more capital, and you don’t need to pay a rental-style daily cost. <hr /> This article is general in nature, and should not be considered financial advice. For advice tailored to your individual situation and your personal finances, please see a qualified financial planner. Correction: this article previously stated the amount of lump sum deposit will not be counted as an asset in the aged-care means test, as a pro of option 2. In fact, the amount of lump sum deposit will not be counted as an asset in the pension means test.<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/161674/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/colin-zhang-1234147">Colin Zhang</a>, Lecturer, Department of Actuarial Studies and Business Analytics, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"World's biggest" amber nugget worth over $1 million used as doorstop for decades

An elderly woman in Romania has unknowingly used one of the largest known amber nuggets in the world - worth over €1 million ($1.6 million) - as her doorstop for decades. The woman found the stone in the bed of a stream in Colti, a village in the southeast Romania, and used it as her doorstop for years without realising its value. Members of her family also reported that thieves had once broken into her home, but only stole a few pieces of gold jewelry, missing the seemingly insignificant rock. “In their frantic search for valuables, they overlooked the real treasure that was there before their eyes,” they said. It wasn't until after the woman died in 1991 that a relative who inherited her home suspected the doorstop might be more than meets the eye - and he was right. When he sold the amber to the Romanian state, experts at the Museum of History in Krakow, Poland appraised the rock and found that the amber is likely between around 38 and 70 million years old. “Its discovery represents a great significance both at a scientific level and at a museum level,” Daniel Costache, director of the Provincial Museum of Buzau, told local news outlet El Pais. The expert also claimed that the amber is one of the largest pieces in the world and the largest of its kind weighing a hefty 3.5-kilograms. It has now been classified as a national treasure of Romania, and can be found in the Provincial Museum of Buzau, where it has been since 2022. Romania is one of the countries with significant deposits of amber, with Buzau County being one of the areas where you can find these beautiful stones in abundance. The protected area also contains the old Stramba amber mine, which was very productive during the first half of the 21st century, before it was shut down by the communist regime as it was considered unprofitable.

Jessica Alba surprises dad by buying his childhood home

Jessica Alba has spent the past three years working towards buying her parents a house, but not just any house, she bought her father's childhood home. She took to Instagram to make the announcement, with a teaser video of her special home-renovation project. "Almost three years ago, I started the project of my dreams… I surprised my parents by buying them a house!!" she began. "Now, it wasn't just any house – it was extra sentimental as it was my grandparent's house that my father grew up in," she continued. "After my grandfather passed away, my parents were planning on selling the house in order to pay for my grandmother's medical bills. Well… I pretended like I was going to help them flip it before selling when in reality, I had planned to buy it for them all along." <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/reel/C_TWEyhPyy_/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/C_TWEyhPyy_/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Jessica Alba (@jessicaalba)</a> </div> </blockquote> She published the first part of her renovation series on YouTube and in it explained the sentimental value of the house and how it was a symbol for her father, who was an immigrant from Mexico, that "he had made it". Her family initially planned to sell it to ease some of their financial burden, as her grandmother required "24/7 care" but Alba wanted to keep the house in the family and so her plan began. "Instead of it giving to a stranger, I wanted to keep this home in our family," she said in the YouTube series. The moment Alba surprised her parents was also captured in the video, with her father brought to tears as he was overcome with emotion. "That's so sweet Jessica. That's a big surprise," he said while embracing his daughter. "I'm very proud of you." Images: Instagram
