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

<div class="theconversation-article-body"> <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.

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

<div class="theconversation-article-body"> <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?

Uproar over council's bin "shaming" move

As councils around the country make big changes to the way we dispose of waste, one council's move has left an entire street in Melbourne "offended". On Wednesday morning, Essendon mum Kali took out her bins and thought nothing more of her weekly habit. It was when she came back after a coffee run that she spotted a tag that had "oh no" written in big red letters. "We found items that don't belong in your mixed recycling bin," the note read, identifying reusable shopping bags as the culprit. When she looked around all but one household on her street had the same yellow note. "I came back and saw all these tags on the bins, I thought 'That's a bit weird'," she told Yahoo News Australia. "It was the talk of the street," she said, after finding out that fellow residents were in "uproar" over the tags. Kali, a mum-of-two, has lived in her home for over nine years and said this was the first time she saw the tag on her bin. "It's just a bizarre thing to do," she said. "I thought it was funny that I got bin shamed. I'm sure we're all guilty of [recycling incorrectly], it's an easy mistake. "Our whole street was embarrassed about it," she added, saying "other neighbours were more offended". Kali is adamant that she didn't do anything wrong, as she ensures the bags in her bin were made out of paper, but said that "you don’t know who is putting things in your bin." A council spokesperson told Yahoo that the move was made to "inform" residents. "Council’s intention is to provide information to people at their homes through our kerbside bin education program to create more awareness, so everyone in the community can recycle right," the spokesperson said. "We understand that recycling can be confusing and that there may be a misunderstanding in what can and can’t go into a recycling bin." Images: Yahoo News

$15 Kmart hack that'll transform your kitchen

Who doesn't love a cheap hack? For the past few months shoppers have been obsessed with a $15 bathroom item from Kmart, but not for its intended use. Shoppers have used the retailer’s 3 Tier Floor Caddy, which was originally designed to organise toiletries and save floor space, as a coffee station that's not only practical, but looks nice as well. One shopper took it to the next level, by using the $31 Flexi Storage Decorative Shelving from Bunnings and attaching it to two of the Kmart floor caddies to display plants alongside the DIY coffee station. She initially bought the shelves to install on her kitchen wall, but after finding out they weren't sturdy enough, it has been sitting in her home, until she saw the Kmart caddy hack. “I bought these floating shelves from Bunnings but after reading the reviews I found that people had said they are not great! And I was too lazy to take them back,” she wrote. “Then I saw this Kmart hack with the shower caddies and I’m very happy with the result.” Shoppers were impressed with the finished results, praising the "incredible" idea. “This looks excellent. Like you, we have a small kitchen with very limited shelving. You’ve inspired me to do the same,” one wrote. “Awesome, looks amazing,” another added, while a third commented, “That’s so clever, thanks for sharing”. However a few others didn't get the hype, with one saying: “I don’t get coffee stations. Not saying it’s bad. Just think it creates more clutter." Image: Facebook/ Kmart

Ian Thorpe lists luxury home at a discount

Ian Thorpe has returned his luxury Woollahra townhouse to the market for a price of $3.5 million. The Olympic gold medallist previously listed it on the market for $3.7 million in September last year but failed to find a buyer at that price. The townhouse boasts four-bedrooms and three-bathrooms and sits on 250sqm of land. It also has an outdoor swimming pool and a beautiful outdoor tropical garden. Thorpe purchased the home in December 2017 for $2.75 million and has since done extensive renovation work to the property. He remodelled the terrace and added in stylish sliding doors. It also features open plan living areas perfect for families. "It's completely private and secluded," letting agent Courtney Wong told The Sydney Morning Herald in 2023. A description for the property reads: "For those seeking a private escape with all the comforts of a luxury home, this is everything you could have dreamed of and more. "A true gem tucked away at the quiet rear of a boutique block of only six, this residence represents the perfect mix of modernity and the natural world with its contemporary architectural design in a tranquil leafy setting."

"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.

Elsewhere across Australia, winter temperatures have been <a href="https://www.theguardian.com/australia-news/article/2024/aug/28/nsw-weather-forecast-fire-danger-warnings-sydney-bom">way above average</a>. We can look to the positives: spring <a href="https://www.theguardian.com/australia-news/article/2024/aug/26/australias-early-spring-brings-budding-flowers-chirping-birds-and-climate-alarm">flowers are blooming early</a>, and people have donned t-shirts and <a href="https://www.smh.com.au/environment/climate-change/spring-comes-early-after-warm-winter-with-more-heat-on-the-way-20240828-p5k63i.html">hit the beach</a>. But there’s a frightening undercurrent to this weather. Earth’s climate has become dangerously <a href="https://science.nasa.gov/climate-change/extreme-weather/">unstable</a>, and it’s only a matter of time before we get the bad combination of hot and dry weather, strong winds and a spark. None of this should come as a surprise. The sooner we stop expecting Australia’s weather to be “normal”, the sooner we can prepare for life in a wild climate. <figure><iframe src="https://www.youtube.com/embed/003XSg5AZBk?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>The green is deceiving</h2> The landscape around Sydney – and in fact, across much of south-east Australia – is very green at the moment. That’s because we’ve had a couple of years of good rains which triggered an explosion of vegetation growth. The below NASA satellite image reveals the picture in stark detail. It’s certainly lush out there at the moment. But the problem with climate change is that weather conditions can turn on a dime. This August was a case in point. At month’s end, much of Australia was hit by a record-breaking heatwave and <a href="http://www.bom.gov.au/australia/charts/synoptic_col.shtml">damaging winds</a> – conditions that can dry out a green landscape with devastating efficiency, turning it into fuel for a bushfire. The dangerous fire weather that struck Sydney this week came as a surprise to many. But in reality, these abnormal conditions are the new normal. We must open our minds to this, if we want to be prepared. <h2>A climate off the rails</h2> The year 2023 was Earth’s <a href="https://www.climate.gov/news-features/featured-images/2023-was-warmest-year-modern-temperature-record#:%7E:text=The%20year%202023%20was%20the,decade%20(2014%E2%80%932023).">hottest on record</a>. And <a href="https://www.carbonbrief.org/state-of-the-climate-2024-now-very-likely-to-be-warmest-year-on-record/">2024 looks likely</a> to be hotter still. In Australia, the last 12 months have provided all the evidence we need that our climate is wobbling on its rails. In October 2023, Victoria’s Gippsland region suffered unseasonably early bushfires, then soon after battled <a href="https://www.abc.net.au/news/2023-12-05/gippsland-fires-and-multiple-floods-breeding-resilience/103179368">heavy rain and flooding</a>. And Tasmania, where I live, <a href="https://www.abc.net.au/news/2024-03-07/tas-drought-conditions-as-dry-tasmania-looking-very-brown/103546058">has been gripped by drought</a>. This February was Hobart’s third driest in 143 years. But over the weekend we were hammered by a <a href="https://www.abc.net.au/news/2024-09-01/tas-flood-warnings-severe-weather-sunday/104296092">deluge of rain and wind</a>. This climate instability is setting up bad fire conditions. Not everywhere in south-east Australia will be hit by fire, but it will happen somewhere. It could be the hinterlands or the coast. It will depend on how our erratic climate behaves in the coming months. Let’s stick with the Tasmania example. Sure, the surface soils are now nicely saturated. But that will lead to a burst of grass and other vegetation in spring. If the dry weather returns and the temperatures heat up in summer, the fine fuels will dry out and become dangerously combustible. All we need then is a windy day and a spark, and a nightmare fire will soon be racing across the landscape. <h2>Canada on fire</h2> Of course, Australia is not the only country facing climate instability and a worsening fire risk. Canada suffered a catastrophic wildfire season in 2023 – one of the most severe on record. It burnt almost 15 million hectares and forced the evacuation of 232,000 people. Smoke produced by the fires affected communities up to 1,000 km away, such as in southern Canada and on the east coast of the United States. A <a href="https://www.nature.com/articles/d41586-024-02653-6">recent paper</a> in the journal Nature Communications outlined why. It pinpointed early snowmelt, early-season drought conditions and intense heat. In fact, the average temperature in Canada from May to October last year was 2.2°C higher than the 30-year average. The researchers said human-caused climate change exacerbated the fire’s effects. It went on: <blockquote> The disproportionate effect a few days of extreme weather can have on the total area burned is also evident in this fire season, leading to worrisome prospects given projected future conditions. </blockquote> <h2>Normal no longer exists</h2> It’s always been difficult to forecast fire seasons in Australia, due to our natural climate variability. But now we are seeing climate instability <a href="https://www.csiro.au/en/research/environmental-impacts/climate-change/state-of-the-climate/previous/state-of-the-climate-2018/australias-changing-climate">layering over itself</a>: background dryness, wet seasons bringing a proliferation of fuels, and above-average temperatures. Eventually we’ll get unlucky and experience extremely strong winds thrown into the mix. That’s when catastrophic fires are most likely to occur. As we saw in the <a href="https://theconversation.com/australias-black-summer-of-fire-was-not-normal-and-we-can-prove-it-172506">Black Summer of 2019–20</a>, and again in Canada last year, some fires are so intense they completely overwhelm fire suppression strategies. Under climate change, the likelihood of getting a bad combination of weather conditions is increasing. So what’s the remedy? Australia really must start making our communities more resilient. Serious and sustained adaptation is needed. As my <a href="https://www.science.org/doi/full/10.1126/science.adi8066">research has outlined</a>, this requires the careful integration of: <ul> <li>community education programs</li> <li>research and development to design fire-safe homes, gardens, communities and bushland</li> <li>incentives and penalties to ensure adaptation measures are implemented.</li> </ul> As this winter has shown, Australia’s climate is entering a different phase. It’s time to give up on “normal” weather. The game is changing and we have to adapt.<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/237857/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/david-bowman-4397">David Bowman</a>, Professor of Pyrogeography and Fire Science, <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.

Travel Trouble

40°C in August? A climate expert explains why Australia is ridiculously hot right now

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> It’s winter in Australia, but as you’ve probably noticed, the weather is unusually warm. The top temperatures over large parts of the country this weekend were well above average for this time of year. The outback town of Oodnadatta in South Australia recorded 38.5°C on Friday and 39.4°C on Saturday – about 16°C above average. Both days were well above the state’s previous winter temperature record. In large parts of Australia, the heat is expected to persist into the coming week. A high pressure system is bringing this unusual heat – and it’s hanging around. So temperature records have already fallen and may continue to be broken for some towns in the next few days. It’s no secret the world is warming. In fact, 2024 is shaping up to be <a href="https://www.carbonbrief.org/state-of-the-climate-2024-now-very-likely-to-be-warmest-year-on-record/">the hottest year on record</a>. Climate change is upon us. Historical averages are becoming just that: a thing of the past. That’s why this winter heat is concerning. The warming trend will continue for at least as long as we keep burning fossil fuels and polluting the atmosphere. Remember, this is only August. The heatwaves of spring and summer are only going to be hotter. <figure><iframe src="https://www.youtube.com/embed/GmhMKjxEGQo?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Widespread heat forecast for Australia in August, 2024 (Bureau of Meteorology)</figcaption></figure> <h2>Records broken across Australia</h2> The Bureau of Meteorology was expecting many records to be broken over the weekend across several states. On Thursday, bureau meteorologist Angus Hines described: <blockquote> A scorching end to winter, with widespread heat around the country in coming days, including the chance of winter records across multiple states for maximum temperature. </blockquote> The amount of heat plunging into central Australia was particularly unusual, Hines said. On Friday, temperatures across northern South Australia and southern parts of the Northern Territory were as much as 15°C above average. Temperatures continued to soar across northern parts of Western Australia over the weekend, with over 40°C recorded at Fitzroy Crossing on Sunday. It has been 2–12°C above average from Townsville all the way down to Melbourne for several days in a row. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?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/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=412&fit=crop&dpr=1 600w, https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=412&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=412&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=518&fit=crop&dpr=1 754w, https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=518&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/615457/original/file-20240825-18-d8f6ho.gif?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=518&fit=crop&dpr=3 2262w" alt="Animated maximum temperature anomaly map showing heat building across central Australia" /></a><figcaption>Maximum temperature anomalies from August 19-24, showing heat building across Australia. Bureau of Meteorology, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> Bear in mind, it’s only August. As Hines said, the fire weather season hasn’t yet hit most of Australia – but the current conditions – hot, dry and sometimes windy – are bringing moderate to high fire danger across Australia. It may also bring dusty conditions to central Australia. And for latitudes north of Sydney and Perth, most of the coming week will be warm. <h2>What’s causing the winter warmth?</h2> <a href="http://www.bom.gov.au/australia/charts/synoptic_col.shtml">In recent days</a> a stubborn high pressure system has sat over eastern Australia and the Tasman Sea. It has kept skies clear over much of the continent and brought northerly winds over many areas, transporting warm air to the south. High pressure promotes warm weather – both through clearer skies that bring more sunshine, and by promoting the descent of air which <a href="https://media.bom.gov.au/social/blog/2544/explainer-what-influences-air-temperature/">causes heating</a>. By late August, both the intensity of the sun and the length of the day has increased. So the centre of Australia can really warm up when under the right conditions. High pressure in June can be associated with cooler conditions, because more heat is lost from the surface during those long winter nights. But that’s already less of an issue by late August. This kind of weather setup has occurred in the past. Late-winter or early-spring heat does sometimes occur in Australia. However, this warm spell is exceptional, as highlighted by the broken temperature records across the country. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?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/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/615284/original/file-20240823-20-1mu7h0.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="Graph of August Australian-average temperatures increasing since 1910" /></a><figcaption>August temperatures have been rising over the past century. Bureau of Meteorology</figcaption></figure> <h2>Feeling the heat</h2> The consequences of humanity’s continued greenhouse gas emissions are clear. Australia’s winters are getting warmer overall. And winter “heatwaves” are becoming warmer. Australia’s three warmest Augusts on record have all occurred since 2000 – and <a href="https://theconversation.com/why-is-australia-having-such-a-warm-winter-a-climate-expert-explains-210693">last August was the second-warmest since 1910</a>. When the right weather conditions occur for winter warmth across Australia, the temperatures are higher than a century ago. The warmth we are experiencing now comes off the back of <a href="https://theconversation.com/earth-has-just-ended-a-13-month-streak-of-record-heat-heres-what-to-expect-next-236655">a recent run of global temperature records</a> and <a href="https://theconversation.com/extreme-heat-is-breaking-global-records-why-this-isnt-just-summer-and-what-climate-change-has-to-do-with-it-234249">extreme heat events across the Northern Hemisphere</a>. This warm spell is set to continue, with temperatures above 30°C forecast from Wednesday through to Sunday in Brisbane. The outlook for spring points to continued <a href="http://www.bom.gov.au/climate/outlooks/#/temperature/maximum/median/seasonal/0">above-normal temperatures</a> across the continent, but as always we will likely see both warm and cold spells at times. Such winter warmth is exceptional and already breaking records. Climate change is already increasing the frequency and intensity of this kind of winter heat – and future warm spells will be hotter still, if humanity’s greenhouse gas emissions continue.<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/237398/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, Senior Lecturer in Climate Science, <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.

Domestic Travel

No, your aches and pains don’t get worse in the cold. So why do we think they do?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/manuela-ferreira-161420">Manuela Ferreira</a>, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a> and <a href="https://theconversation.com/profiles/leticia-deveza-1550633">Leticia Deveza</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> It’s cold and wet outside. As you get out of bed, you can feel it in your bones. Your right knee is flaring up again. That’ll make it harder for you to walk the dog or go to the gym. You think it must be because of the weather. It’s a common idea, but a myth. When we looked at the evidence, <a href="https://www.sciencedirect.com/science/article/pii/S0049017224000337">we found</a> no direct link between most common aches and pains and the weather. In the first study of its kind, we found no direct link between the temperature or humidity with most joint or muscle aches and pains. So why are so many of us convinced the weather’s to blame? Here’s what we think is really going on. <h2>Weather can be linked to your health</h2> The weather is often associated with the risk of new and ongoing health conditions. For example, cold temperatures <a href="https://pubmed.ncbi.nlm.nih.gov/27021573/">may worsen</a> asthma symptoms. Hot temperatures <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(22)00117-6/fulltext">increase the risk</a> of heart problems, such as arrhythmia (irregular heartbeat), cardiac arrest and coronary heart disease. Many people are also convinced the weather is linked to their aches and pains. For example, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1479-8077.2004.00099.x?casa_token=jvpSbA4szqoAAAAA%3ATyHyGaqXmfevWyuJe6LW_3Pap3IPHC8HSMTl3RN63mFzNO0X7ozQjBb6Bi3yVFuPjqkrf-WlB-J5A1q1">two in every three</a> people with knee, hip or hand osteoarthritis <a href="https://bmcmusculoskeletdisord.biomedcentral.com/articles/10.1186/1471-2474-15-66">say</a> cold temperatures trigger their symptoms. Musculoskeletal conditions affect more than <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/musculoskeletal-conditions-comorbidity-australia/summary">seven million Australians</a>. So we set out to find out whether weather is really the culprit behind winter flare-ups. <h2>What we did</h2> Very few studies have been specifically and appropriately designed to look for any direct link between weather changes and joint or muscle pain. And ours is the first to evaluate data from these particular studies. We looked at data from more than 15,000 people from around the world. Together, these people reported more than 28,000 episodes of pain, mostly back pain, knee or hip osteoarthritis. People with rheumatoid arthritis and gout were also included. We then compared the frequency of those pain reports between different types of weather: hot or cold, humid or dry, rainy, windy, as well as some combinations (for example, hot and humid versus cold and dry). <h2>What we found</h2> We found changes in air temperature, humidity, air pressure and rainfall do not increase the risk of knee, hip or lower back pain symptoms and are not associated with people seeking care for a new episode of arthritis. The results of this study suggest we do not experience joint or muscle pain flare-ups as a result of changes in the weather, and a cold day will not increase our risk of having knee or back pain. In order words, there is no direct link between the weather and back, knee or hip pain, nor will it give you arthritis. It is important to note, though, that very cold air temperatures (under 10°C) were rarely studied so we cannot make conclusions about worsening symptoms in more extreme changes in the weather. The only exception to our findings was for gout, an inflammatory type of arthritis that can come and go. Here, pain increased in warmer, dry conditions. Gout has a very different underlying biological mechanism to back pain or knee and hip osteoarthritis, which may explain our results. The combination of warm and dry weather may lead to increased dehydration and consequently increased concentration of uric acid in the blood, and deposition of uric acid crystals in the joint in people with gout, resulting in a flare-up. <h2>Why do people blame the weather?</h2> The weather can influence other factors and behaviours that consequently shape how we perceive and manage pain. For example, some people may change their physical activity routine during winter, choosing the couch over the gym. And we know <a href="https://pubmed.ncbi.nlm.nih.gov/28700451/">prolonged sitting</a>, for instance, is directly linked to worse back pain. Others may change their sleep routine or sleep less well when it is either too cold or too warm. Once again, a bad night’s sleep can trigger your <a href="https://link.springer.com/article/10.1007/s00586-021-06730-6">back</a> and <a href="https://www.sciencedirect.com/science/article/pii/S1063458421007020">knee</a> pain. Likewise, changes in mood, often experienced in cold weather, trigger increases in both <a href="https://link.springer.com/article/10.1007/s00586-021-06730-6">back</a> and <a href="https://www.sciencedirect.com/science/article/pii/S1063458421007020">knee</a> pain. So these changes in behaviour over winter may contribute to more aches and pains, and not the weather itself. Believing our pain will feel worse in winter (even if this is not the case) may also make us feel worse in winter. This is known as the <a href="https://link.springer.com/article/10.1186/s12891-018-1943-8">nocebo effect</a>. <h2>What to do about winter aches and pains?</h2> It’s best to focus on risk factors for pain you can control and modify, rather than ones you can’t (such as the weather). You can: <ul> <li> become more physically active. This winter, and throughout the year, aim to walk more, or talk to your health-care provider about gentle exercises you can safely do at home, with a physiotherapist, personal trainer or at the pool </li> <li> lose weight if obese or overweight, as this is linked to <a href="https://jamanetwork.com/journals/jama/article-abstract/2799405">lower levels</a> of joint pain and better physical function </li> <li> keep your body warm in winter if you feel some muscle tension in uncomfortably cold conditions. Also ensure your bedroom is nice and warm as we tend to sleep <a href="https://www.sciencedirect.com/science/article/pii/S0033350623003359">less well</a> in cold rooms </li> <li> maintain a healthy diet and <a href="https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9913(23)00098-X/fulltext">avoid smoking</a> or drinking high levels of alcohol. These are among <a href="https://ard.bmj.com/content/annrheumdis/82/1/48.full.pdf">key lifestyle recommendations</a> to better manage many types of arthritis and musculoskeletal conditions. For people with back pain, for example, a healthy lifestyle is linked with <a href="https://pubmed.ncbi.nlm.nih.gov/36208321/">higher levels</a> of physical function.<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/235117/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ul> <a href="https://theconversation.com/profiles/manuela-ferreira-161420">Manuela Ferreira</a>, Professor of Musculoskeletal Health, Head of Musculoskeletal Program, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a> and <a href="https://theconversation.com/profiles/leticia-deveza-1550633">Leticia Deveza</a>, Rheumatologist and Research Fellow, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Antarctic heat, wild Australian winter: what’s happening to the weather and what it means for the rest of the year

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/martin-jucker-379172">Martin Jucker</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Australia’s south and east have seen <a href="https://theconversation.com/southern-australia-is-freezing-how-can-it-be-so-cold-in-a-warming-climate-233977">freezing temperatures</a> and <a href="https://www.theguardian.com/australia-news/article/2024/jul/29/australia-winter-weather-forecast-east-coast-colder-records">wild weather</a> this winter. At the same time, the continent as a whole – and the globe – have <a href="https://www.abc.net.au/news/2024-08-03/australia-suffers-cold-winter-weather-despite-mild-forecast/104176284">continued to warm</a>. What’s going on? As ever, it’s hard to pinpoint a single cause for weather events. But a key player is likely an event unfolding high above Antarctica, which itself may have been triggered by a heatwave at surface level on the frozen continent. Here’s what’s happening – and what it might mean for the rest of this year’s weather. <h2>When the stratosphere heats up</h2> Out story begins in the cold air over Antarctica. July temperatures in the stratosphere, the layer of air stretching between altitudes of around 10 and 50 kilometres, are typically around –80°C. The winds are also very strong, averaging about 300 kilometres per hour in winter. These cold, fast winds loop around above the pole in what is called the <a href="https://sites.krieger.jhu.edu/waugh/research/polarvortex">stratospheric polar vortex</a>. Occasionally, persistent high air pressure in the lower atmosphere can influence large-scale waves that extend around the globe and up into the stratosphere. There they cause the strong winds to slow down, and the air high above the pole to become much warmer than normal. In extreme situations the stratospheric winds can completely break down, in what is called a “sudden stratospheric warming” event. These events occur every few years in the northern hemisphere, but only one has ever been observed in the south, in 2002 (though another <a href="https://theconversation.com/the-air-above-antarctica-is-suddenly-getting-warmer-heres-what-it-means-for-australia-123080">almost happened in 2019</a>). <h2>Pushing polar weather our way</h2> Once the polar vortex is disturbed, it can in turn influence the weather at the surface by steering weather systems from the Southern Ocean towards the Equator. However, this is a slow process. The impact at the surface may not be felt until <a href="https://doi.org/10.1175/JCLI-D-22-0425.1">a few weeks or even months</a> after the initial weakening of the stratospheric polar vortex. Once it begins, the stratospheric influence can prevail for more weeks or months, and helps meteorologists make <a href="https://doi.org/10.5194/acp-22-2601-2022">long-range weather forecasts</a>. In climate science terms, the weak stratospheric winds put an atmospheric system called the <a href="http://www.bom.gov.au/climate/sam/">Southern Annular Mode</a> into a negative phase. The main effect of this on surface weather is to bring westerly winds further north. In winter, this means polar air outbreaks can reach places like Sydney more easily. As a result, we see more <a href="https://doi.org/10.1175/JCLI4134.1">rain over much of southern Australia</a>, and snowfall in alpine regions. In spring and summer it means westerly winds blow over the continent before reaching the east coast, bringing warm and dry air to southeastern Australia. The exact impact of a weaker polar vortex depends on how much and for how long the weather systems are being pushed further northward. It will also depend on other weather influencers such as El Niño and the Indian Ocean Dipole. <h1>This winter’s weirdness</h1> Unpicking exactly why any weather event occurs is tricky at the moment, because global weather has been absolutely crazy over the past 12 months or so. Global temperatures are <a href="https://theconversation.com/we-just-blew-past-1-5-degrees-game-over-on-climate-not-yet-213364">much higher than usual</a>, which is making unusual weather very common. But there are indications that the stratosphere is having some influence on our weather this winter. The stratospheric polar vortex started to warm in mid-July, and is about 20°C warmer than the long-term average. At the time of writing, the winds slowed down to about 230 kilometres per hour, 70 kilometres per hour slower than average. These numbers mean that, technically, the event does not qualify as a sudden stratospheric warming. However, further warming may still occur. If we look at how southern hemisphere winds have evolved in the past few weeks, we see a pattern which looks like what we would expect from a sudden stratospheric warming. First, we see warming in the stratosphere which is <a href="https://doi.org/10.1029/2021GL095270">at first accompanied by a poleward shift of weather systems</a>. The stratosphere’s influence then propagates downward and seems to <a href="https://doi.org/10.1175/JCLI-D-22-0425.1">induce many weeks</a> of weather systems shifted towards the equator. This coincides with the period of cold and rainy weather along Australia’s east coast in late July and the beginning of August. Forecasts suggest the Southern Annular Mode will be a long way from normal conditions in the first half of August – four standard deviations below average, which is extremely rare. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?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/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=300&fit=crop&dpr=1 600w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=300&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=300&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=377&fit=crop&dpr=1 754w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=377&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/611211/original/file-20240804-19-sp862a.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=377&fit=crop&dpr=3 2262w" alt="Diagram showing atmospheric warming and winds" /></a><figcaption>How initial warming high in the stratosphere ends up changing winds near the surface and pushing polar weather further north. <a class="source" href="https://stratobserve.com">Z.D.

Weather over the Amundsen Sea near Antarctica in the South Pacific is <a href="https://doi.org/10.1175/JCLI-D-22-0425.1">an important source</a> of these disturbances. This year, we have seen disturbances of this sort. There have been <a href="https://www.theguardian.com/world/article/2024/aug/01/antarctic-temperatures-rise-10c-above-average-in-near-record-heatwave">near-record surface temperatures around Antarctica</a>.

But more research will be required to confirm the causes. <h1>What should we expect for the rest of the year?</h1> There are two pathways until the end of the year. One is that the stratospheric winds and temperatures recover to their usual values and no longer influence surface weather. This is what the forecasts from <a href="https://ozonewatch.gsfc.nasa.gov">Ozone Watch</a> seem to suggest. Another is that the stratosphere keeps warming and the winds keep being slower all the way into summer. In this scenario, we would expect a persistent negative Southern Annular Mode, which would mean a spring and potentially even summer with warmer and drier than usual weather over southeastern Australia, and a small ozone hole.

Snug but unsafe: your heater may be harming your health. What are your safest choices?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/christine-cowie-191638">Christine Cowie</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/bill-dodd-1280161">Bill Dodd</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> We now have a dizzying array of heating technologies to consider, besides the fire that warmed our ancestors. Salespeople will highlight any number of features and minor conveniences. You will be made aware of limited-offer discounts, product warranties, trends in certain Nordic countries, or their low cost (at least in the short-term). What you are less likely to read on the box is, well, the stuff that really matters: the long-term effects on your health and the health of your family, your neighbours and the environment. Yes, a heater should keep you warm affordably. After all, a warm home is vital for your health. But would you run a heater that you knew was increasing the likelihood of your child developing asthma, your partner developing lung cancer, and your neighbour or your grandparent suffering a stroke or heart attack? Many <a href="https://doi.org/10.1016/j.envint.2019.105429">peer-reviewed studies</a> have found domestic heating to be a major source of air pollution and of ill health in Australia. So which heaters are high-risk and which are low-risk? Let’s consider, firstly, the most dangerous heaters. <h2>Extreme-risk heaters</h2> Two rules reduce the risks: <ol> <li> never burn anything (wood, gas or other fuel) in your home without adequate ventilation such as a chimney, exhaust or flue </li> <li> never use an outdoor appliance (heater, cooker, barbecue) inside. </li> </ol> Concerningly, a 2022 <a href="https://asthma.org.au/wp-content/uploads/2022/11/AA2022_Housing-Survey-Report_full_v4.pdf">Asthma Australia survey</a> found 7% of Australians used an unflued gas heater. When gas or other fuel is burnt indoors it releases a range of <a href="https://search.informit.org/doi/abs/10.3316/informit.786585213635569">particles and toxic gases</a>. Most dangerous of all is <a href="https://www.dcceew.gov.au/environment/protection/npi/substances/fact-sheets/carbon-monoxide-0">carbon monoxide</a> (CO). This colourless, odourless gas can build up in unventilated homes, resulting in serious poisoning and death. A recent <a href="https://www.abc.net.au/news/2024-06-29/sydney-family-use-bbq-as-indoor-heater-inhale-carbon-monoxide/104039702">case of carbon monoxide intoxication</a> left three people unconscious in a Sydney home after an outdoor barbecue was used inside as a heater. Outdoor heaters, cookers and barbecues are especially potent sources of carbon monoxide and should never be brought inside. If you have a gas appliance in your home, even if it is ventilated, install a <a href="https://www.energysafe.vic.gov.au/industry-guidance/gas/gas-information-sheets/gis-36-carbon-monoxide-alarms-domestic-use">carbon monoxide alarm</a> for as little as $30. <h2>High-risk heaters</h2> <a href="https://www.sciencedirect.com/science/article/pii/S0048969724012087">The evidence</a> is now very clear: wood heater smoke is a potent source of air pollution and significant cause of ill-health in Australia. The more often you burn, the greater the risk. One <a href="https://doi.org/10.1016/j.envint.2023.108128">large population study</a> found even infrequent wood heater use (30 days or more each year) increases the risk of lung cancer by 68%. Wood heaters spill smoke into the home when refuelling. They also suck smoke from outside back into the home as air is drawn up the chimney. If you can smell your wood heater, it is harming your health and exposing you to a toxic mix of particles and gases. For the wider community, the cumulative health impacts of wood heaters are significant. Less than <a href="https://www.abs.gov.au/ausstats/abs@.nsf/Previousproducts/4602.0.55.001Main%20Features5Mar%202011?opendocument&tabname=Summary&prodno=4602.0.55.001&issue=Mar%202011&num=&view=">10% of Australian households</a> use a wood heater. Yet they are the largest source of particulate air pollution in most Australian cities and towns, including <a href="https://www.environment.nsw.gov.au/-/media/OEH/Corporate-Site/Documents/Air/sydney-air-quality-study-stage-2-program-report-220644.pdf">Sydney</a>, <a href="http://www.doi.org/10.1016/j.scitotenv.2024.171069">Melbourne</a>, <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.52176">Canberra</a>, <a href="http://www.doi.org/10.1016/j.scitotenv.2024.171069">Adelaide</a> and <a href="http://www.doi.org/10.3390/ijerph17093264">Hobart</a>. Even in temperate Sydney, wood heaters emit <a href="https://www.environment.nsw.gov.au/-/media/OEH/Corporate-Site/Documents/Air/sydney-air-quality-study-stage-2-program-report-220644.pdf">more of this pollution</a> than all the cars, trucks, boats and buses combined, and more than coal-fired power stations and industry. <a href="https://safeair.org.au/">Centre for Safe Air</a> researchers <a href="https://doi.org/10.1016/j.scitotenv.2024.171069">estimate</a> wood heaters cause between 558 and 1,555 excess deaths a year in Australia. That’s roughly equivalent to the <a href="https://www.bitre.gov.au/publications/ongoing/road_deaths_australia_monthly_bulletins">annual road toll</a>. Fine particles (2.5 microns or less in diameter – also known as PM2.5) are a major component of wood smoke. PM2.5 increases <a href="https://www.epa.gov/air-research/air-pollution-and-cardiovascular-disease-basics">rates of heart disease and stroke</a>, <a href="https://doi.org/10.3978%2Fj.issn.2072-1439.2016.01.19">lung disease</a>, <a href="https://doi.org/10.1016/j.scitotenv.2018.11.218">dementia and other neurological conditions</a> and <a href="https://asthma.org.au/about-us/advocacy/air-quality">asthma attacks</a>. Risks of <a href="https://doi.org/10.1371/journal.pmed.1003718">adverse pregnancy outcomes</a> and <a href="https://www.eea.europa.eu/publications/air-pollution-and-childrens-health">poorer learning outcomes in children</a> are also increased. <h2>Low-risk heaters</h2> Evidence suggests there is no “safe” level of air pollution, with health effects <a href="https://doi.org/10.1016/j.envint.2019.02.044">seen at very low levels</a>. Even ducted gas heating, where most of the toxins are ventilated, <a href="https://search.informit.org/doi/abs/10.3316/informit.786585213635569">can expose residents to low levels</a> of PM2.5, nitrogen dioxide (NO2), carbon monoxide and formaldehyde. Over time, this can have a range of <a href="https://safeair.org.au/the-health-impacts-of-gas-use-extraction/#gf_1">health impacts</a>, including worsening asthma and respiratory symptoms. Burning gas for heating also adds to greenhouse gas emissions. As Australia transitions to a zero-carbon society, some states and territories are phasing out installation of new wood heaters, such as <a href="https://www.abc.net.au/news/2023-08-24/canberra-to-phase-out-wood-heaters-by-2045/102769162">in the ACT</a>, and gas connections, such as <a href="https://www.planning.vic.gov.au/guides-and-resources/strategies-and-initiatives/victorias-gas-substitution-roadmap">in Victoria</a>. Subsidies to help people replace unhealthy heaters are excellent investments in the environment, public health and health equity. <h2>Healthy heaters</h2> Ultimately, heaters that do not rely on burning fuel inside the home are the safest, and often more affordable, heating option. A <a href="https://www.abc.net.au/news/2023-07-17/cleaning-filters-in-reverse-cycle-air-conditioner-to-save/102594652">well-maintained</a> reverse-cycle air conditioner, sometimes called a heat pump, actually cleans the air inside your home. These air conditioners have the additional benefit of cooling your home in summer. As heatwaves become more severe and frequent, efficient cooling is <a href="https://www.sciencedirect.com/science/article/pii/S0378778823004152">increasingly important for health</a>. As for affordability, an efficient reverse-cycle air conditioner can be up to <a href="https://www.climatechoices.act.gov.au/__data/assets/pdf_file/0005/1862663/Sustainable-Household-Scheme-A-guide-to-reverse-cycle-systems.pdf">seven times as efficient</a> as a gas wall heater in the energy it uses for a given amount of heat. There are many other <a href="https://www.choice.com.au/home-and-living/heating/electric-heaters/articles/which-electric-heater-type-is-best">electric heating technologies</a> – such as fan heaters, oil column heaters, panel heaters, or infrared heaters – that do not release toxins into the home. Heater manufacturers are often reluctant to talk about the health impacts of their products, and regulators are slow to catch up with the science. By thinking about heating in terms of health, you can make your home safer for yourself and the people around you.

Doctor shares her holy grail tips for overcoming eye sensitivity

As the chill of winter sets in, many people find that their eyes become more sensitive and prone to dryness. This can be particularly challenging for those who already suffer from dry eye syndrome. Dr. Jacqueline Beltz is a leading Australian Ophthalmologist and the founder of <a href="https://www.okkiyo.com" target="_blank" rel="noopener">OKKIYO</a>, a beauty brand that makes PRIORITEYES mascara for people with sensitive eyes. Dr Beltz has shared her insights into dry eye syndrome and how winter can exacerbate symptoms, also sharing her top tips for managing eye sensitivity during the colder months. Understanding Dry Eye Syndrome The surface of the eye is covered by a delicate layer of tears, essential for comfort, vision, protection, and nutrition. The tear film comprises two main layers: an outer lipid (oily) layer and an inner aqueous (watery) layer. The lipid layer, produced by oil glands in the eyelids, prevents tears from evaporating too quickly, while the aqueous layer, consisting of water, electrolytes, and proteins, spreads tears evenly across the eye and helps them adhere to the surface. When the balance of tear production, evaporation, absorption, and drainage is disrupted, it can lead to dry eye syndrome. Symptoms may include redness, irritation, a gritty sensation, tired eyes, itching, excessive watering, and fluctuating vision. In severe cases, dry eye can be painful and significantly impact daily life. How common is dry eye syndrome? Dry eye syndrome is a widespread issue, particularly among older adults. According to the Blue Mountains Eye Study, 57% of adults over the age of 50 experience some degree of dry eye. This condition is notably more prevalent in women, with higher rates observed compared to their male counterparts. The increased prevalence in women is often attributed to hormonal changes, particularly during and after menopause. A more recent study, Optometry Australia’s 2022 Vision index found that over 85% of Australians are estimated to have experienced dry eyes at some point in their lives. Of those affected, 55% say they only developed the condition following the beginning of the pandemic in 2020. They reported that almost 1 in 5 (18%) of people experience dry eye symptoms frequently. These statistics highlight the importance of understanding and managing dry eye, especially as we age. DEWS II Study and Treatment Approaches The DEWS II (Dry Eye Workshop II) study provides a comprehensive framework for understanding and treating dry eye syndrome. According to the study, dry eye is a multifactorial disease characterised by a loss of homeostasis (or balance) in the tear film, accompanied by eye symptoms. Factors such as tear film instability, hyperosmolarity (increased saltiness), inflammation, and neurosensory (altered feelings or sensations) abnormalities play significant roles. There are two primary types of dry eye: aqueous deficient and evaporative. Most individuals have a combination of both. Aqueous deficient dry eye occurs when there is insufficient production of the watery layer of tears, often due to aging, hormonal changes, or certain medications. Evaporative dry eye is typically caused by environmental factors or conditions affecting the lipid layer, such as meibomian gland dysfunction (MGD). Winter's Impact on Dry Eyes Winter poses unique challenges for dry eye sufferers. Cold, dry air, indoor heating, and wind can all exacerbate symptoms. Here's how to combat these winter-specific issues: 1. Humidify Your Environment Indoor heating reduces humidity levels, leading to increased tear evaporation. Consider using a humidifier to maintain moisture in the air, especially in bedrooms and living spaces. This helps keep your eyes hydrated. 2. Protect Your Eyes Outdoors Cold winds can strip away the tear film. When outside, wear wraparound sunglasses to shield your eyes from the elements. This not only protects your eyes from the wind but also from UV rays, which can be strong even in winter. 3. Stay Hydrated Dehydration can worsen dry eye symptoms. Drink plenty of water throughout the day to maintain overall hydration, which supports healthy tear production. 4. Optimise Your Diet Certain foods can promote eye health. Omega-3 fatty acids, found in fish like salmon and flaxseeds, have anti-inflammatory properties that can help manage dry eye symptoms. Incorporate these into your diet for added benefits. 5. Use a Warm Compress A warm compress can help improve the function of the meibomian glands, which produce the oily layer of the tear film. This is particularly helpful for those with meibomian gland dysfunction, or MGD. Gently apply a warm, damp cloth to your closed eyelids for 10-15 minutes, followed by a gentle massage of the eyelids to encourage oil secretion. It is important to avoid rubbing or compressing the eyeballs. 6. Use Over-the-Counter Lubricant Eye Drops Artificial tears can provide temporary relief by supplementing the natural tear film. Choose preservative-free options to avoid further irritation, and use them frequently. 7. Remember to have regular eye checks In Australia, Optometrists provide our primary eye health check ups. Dr Beltz recommends adults over the age of 40 see their optometrist once a year, but if you’re struggling with symptoms of dry eye in winter, an extra check up might help and your optometrist will be able to help you to come up with an individualised treatment plan. 8. Invest in Quality Eye Products For those who wear makeup, using products designed for sensitive eyes is crucial. <a href="https://www.okkiyo.com/products/protect-and-preserve-mascara" target="_blank" rel="noopener">PRIORITEYES</a> mascara by OKKIYO has been specifically formulated to be gentle on sensitive eyes, avoiding common irritants while providing excellent performance. Managing Dry Eye in Winter: A Recap Winter can be tough on our eyes, but with the right strategies, you can manage dry eye symptoms effectively. Maintain a humid environment, protect your eyes from cold winds, stay hydrated, and incorporate eye-healthy foods into your diet. Regularly use warm compresses and opt for gentle, high-quality eye products like PRIORITEYES mascara. Dry eye syndrome may be a common condition, but it doesn't have to dominate your life, especially during the harsh winter months. With these tips, you can keep your eyes comfortable and healthy all season long. For personalised advice and treatment, always consult with your eye care professional. Stay warm, stay hydrated and take care of your eyes this winter! Image credits: Shutterstock

New York City mocked for only just discovering wheelie bins

New York City has been trolled online after discovering wheelie bins for the first time. In order to tackle the "trash revolution", the mayor of NYC Eric Adams announced that wheelie bins will be introduced city wide, instead of the current system which is just leaving rubbish bags on the street. Despite the introduction of wheelie bins being a great solution for the city's trash and rodent problem, many were shocked to learn that the receptacles don't already exist there. Introducing the roll out, Mayor Adams began his press conference rolling in a bin and proudly demonstrating how to use it before celebrating with colleagues. He said “many people thought it was impossible” that these wheelie bins were going to be part of the city’s “trash revolution”. “We all have one unified dislike, and those are those pesky New York City rats,” Mr Adams said. “They’re getting more and more bold. They no longer run from you. They just hang out and just do what they want. We want to make sure we change that in a real way.” NYC department of sanitation commissioner Jessica Tisch described the official NYC bin as a “beautiful, rat-fighting piece of engineering” to conquer the estimated three million rats that dominate the streets. The wheelie bin announcement, which was intended to impress New Yorkers, has also gone global – with Europeans and Australians baffled by concept of wheelie bins being new. “Oh my word! Are they seriously showing their constituents how to use a trash can?” wrote one person. “Huh, they don’t have wheelie bins? What century do they live in?” said a second. “How the hell is this revolutionary??” agreed another. “So they finally figured out putting your trash in piles on the sidewalk is not a good idea,” mocked someone else.

Plastic Free July is a waste of time if the onus is only on consumers

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/bhavna-middha-1061611">Bhavna Middha</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> and <a href="https://theconversation.com/profiles/ralph-horne-160543">Ralph Horne</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Every year, the <a href="https://www.plasticfreejuly.org/">Plastic Free July</a> campaign asks us to refuse single-use plastic. The idea is that making a small change in our daily lives will collectively make a big difference. And hopefully, better behaviour will stick and become a habit. The intent is good, but consumers shouldn’t have to bear full responsibility for plastic pollution. Individual sacrifices – particularly temporary ones – <a href="https://www.sciencedirect.com/science/article/abs/pii/S0301421509004728">won’t make a significant difference</a>. Governments, manufacturers and retailers need to get serious about tackling this problem. If Plastic Free July put pressure on the supply side of the equation, rather than demand, it could be more successful. Our research spans food packaging including plastics, waste, sustainable consumption and social practices. We know consumer demand is only one part of the picture. Eliminating plastic waste requires broader systemic changes. <h2>The cabbage dilemma</h2> Research shows consumers generally want to do the <a href="https://www.sustainability.vic.gov.au/news/news-articles/the-conversation-on-sustainability-has-changed">right thing by the environment</a> but find it <a href="https://theconversation.com/households-find-low-waste-living-challenging-heres-what-needs-to-change-197022">challenging</a>. Coming out of a supermarket with no packaging is difficult. There are few unpackaged food items and even when there is a choice, the unpackaged item may be more <a href="https://www.smh.com.au/politics/federal/want-your-fruit-and-veg-without-the-plastic-you-ll-have-to-pay-more-20231107-p5eib4.html">expensive</a>. Have you ever been stuck in the supermarket, choosing between the large head of cabbage you know you won’t finish before it goes bad, or the plastic-wrapped half-cabbage you really need? Consumers should not be forced to choose between food waste (another huge problem) or plastic waste. Maybe there’s another way. For example, why not sell cabbages of different sizes? Why do we need to grow such large heads of cabbage anyway? Both plastic consumption and food waste can be addressed by changing how we produce and distribute certain foods. <h2>Governments, manufacturers and retailers must drive change</h2> The onus for reducing plastic consumption and waste should be placed firmly on those who make plastic and profit from selling their products, as well as those who make and sell products wrapped in plastic packaging. Research has shown just <a href="https://www.csiro.au/en/news/All/News/2024/April/Global-study-finds-more-than-half-of-branded-plastic-pollution-linked-to-56-companies?utm_source=pocket_shared">56 companies</a> globally are responsible for more than half of the branded plastic pollution that ends up in the environment. Companies profit from using plastics because it is cheaper to use than changing to alternatives, such as cardboard or compostable materials, or using less packaging. This means companies choosing to avoid using plastics face unfair competition. It’s a tough habit to kick. Industry-led <a href="https://productstewardship.us/what-is-epr/#:%7E:text=Stewardship%20can%20be%20either%20voluntary,product%20stewardship%20required%20by%20law">voluntary schemes</a> are <a href="https://www.insidewaste.com.au/91038-2-product-stewardship-schemes/">limited in terms of both participation and outcomes</a>. Many companies are failing to meet their own <a href="https://www.asyousow.org/report-page/2024-plastic-promises-scorecard">plastic reduction goals</a>. Governments need to step in and force companies to take responsibility for the plastic and packaging they manufacture. In practice, this could involve similar schemes to the container deposit scheme for beverage containers, or returning plastics to stores. Replacing voluntary schemes with mandatory regulations and increased producer responsibility means companies will have to <a href="https://www.insidewaste.com.au/91038-2-product-stewardship-schemes/">invest in long-term changes designed with care</a>. <figure><iframe src="https://www.youtube.com/embed/UnXVU-06ciI?wmode=transparent&start=1" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>What’s Plastic Free July?</figcaption></figure> <h2>Cities are built around plastic</h2> Our previous research has shown plastic performs an essential role in some, <a href="https://rgs-ibg.onlinelibrary.wiley.com/doi/full/10.1111/geoj.12457">constrained circumstances</a>. We found vulnerable householders often rely on plastic to make life manageable, such as using plastics to cover belongings on the balcony, or using plastic cutlery and plates in student apartments with minimal kitchen space. This includes people with accessibility needs, people relying on public transport to shop for groceries, or people who are financially constrained or living in small high-rise <a href="https://theconversation.com/we-cant-keep-putting-apartment-residents-waste-in-the-too-hard-basket-200545">apartments</a>. Unsustainable lifestyles are not so much a choice as a product of poorly planned cities, housing and regulations. It is all very well if you are mobile and well-located, but if you live in a <a href="https://www.abc.net.au/news/2015-07-08/food-deserts-have-serious-consequences-for-residents-experts/6605230">poorly serviced</a> distant suburb and <a href="https://www.unsw.edu.au/newsroom/news/2023/01/are-you-living-in-a-food-desert--these-maps-suggest-it-can-reall">transport groceries or takeaway food</a> or buy things on the go, then plastic is perhaps the only current affordable way to make it work. So campaigns and solutions that do not consider how <a href="https://rgs-ibg.onlinelibrary.wiley.com/doi/full/10.1111/geoj.12457">everyday lives and economy</a> are intertwined with plastics can <a href="https://www.nature.com/articles/s42949-024-00149-w">exclude people and spaces</a> who can’t access the alternatives. For example, there are ways to make <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1745-5871.12464">convenience eating more sustainable</a> in education settings. We have shown how <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1745-5871.12390">canteens and microwaves</a> in shared spaces can enable people to access affordable food with their friends, as in <a href="https://www.charlesabroad.cz/post/german-university-canteens-why-do-they-beat-the-czech-ones">University Mensa in Germany</a>. Our <a href="https://cur.org.au/project/tackling-food-related-single-use-plastics-in-diverse-consumption-contexts/">new research</a> will explore how single-use food-related plastics and packaging form an integral part of our daily lives, including shopping, work, cooking and storage. Sometimes new policies inadvertently disadvantage certain groups and communities, such as the aged, less mobile, people living in apartments, or low socio-economic groups. Before we roll out new policies and regulations, we need to understand the roles these materials play and the kinds of services and value they provide. We aim to develop a framework to inform policies and strategies that enable a just and inclusive transition to reduced plastic use. <h2>What about after July?</h2> Plastic Free July and similar campaigns are based on idea that making a temporary change will lead to more permanent lifestyle changes. But research shows temporary shifts are <a href="http://www.demand.ac.uk/wp-content/uploads/2016/03/DEMAND2016_Full_paper_42-Shove.pdf">very different</a> to <a href="https://pure.manchester.ac.uk/ws/portalfiles/portal/32468813/FULL_TEXT.PDF">structural, permanent shifts</a> in <a href="https://www.taylorfrancis.com/chapters/edit/10.4324/9781315816494-1/introduction-social-practices-intervention-sustainability-beyond-behaviour-change-yolande-strengers-cecily-maller?context=ubx&refId=d608abad-39f9-4bb2-8754-56e9e2000c5e">practices</a>. Supermarkets will still wrap items in plastic and sell single-use plastic, even if we try to buy less during Plastic Free July. Ultimately, the focus should be on designing effective infrastructure and policy solutions for lasting results, considering how demand for plastic is produced in the first place. Some of these changes will require a shift in community expectations and food culture. Rather than pointing the finger at consumers, let’s get to work on redesigning our cities. We need to rethink how everyday practices, manufacturing and distribution systems are structured to eliminate plastic waste.<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/233436/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/bhavna-middha-1061611">Bhavna Middha</a>, ARC DECRA and Senior Research Fellow, Centre for Urban Research, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> and <a href="https://theconversation.com/profiles/ralph-horne-160543">Ralph Horne</a>, Associate Deputy Vice Chancellor, Research & Innovation, College of Design & Social Context, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The must-visit winter travel destinations

As winter rolls around, many people are looking to flee the confines of their chilly homes and routines in search of sunshine and adventure. Aussies have been already planning their getaways to follow the sun, as <a href="about:blank">Booking.com</a>'s latest search data has revealed the top ten international holiday spots for this year. The results show that while many travellers are heading to tropical destinations this winter, others are searching for a different kind of holiday. 10. Kuta, Bali While Bali has long been a popular tourist destination for Aussies, many chose to head to Indonesia to enjoy the sandy beaches and escape the winter chill. With winter temperatures hovering around 25°C each day, there's no better place to escape the cold. 9. Paris, France In 2024, Paris is on many people’s travel lists ahead of the Olympics in July. With charming restaurants, trendy boutiques, chic cafes, and amazing museums on offer, as well as warm temps, there’s no better time to head to Paris. 8. Ubud, Bali Another Bali region to make the list, Ubud is an inland paradise amongst rice paddies and lush jungle. The food heaven destination is also known for its gorgeous climate, making it a perfect holiday spot. 7. Queenstown, New Zealand For those who don’t want to venture too far from home, Queenstown is an amazing spot for anyone seeking an active holiday. As the only spot on the list which isn't about escaping winter, Queenstown - and New Zealand in general - is often visited by keen skiers and those looking to amplify their winter travels. 6. Canggu, Bali Another Bali spot making the list, Canggu is a beachside area surrounded by terraced rice paddies and known for good surf. Accommodation in the area ranges from beachside villas and gorgeous guesthouses, with something for everyone. 5. Singapore While Singapore has long been a default stopover city for travellers on their way to Europe, it's also a great destination in its own right. With a stunning mix of old town charm and modern skyscrapers, it's the perfect place for a mid-week getaway or long weekend. 4. Legian, Bali Legian Beach is right next to the popular spot Kuta, though is a bit more relaxed and laid-back, and perfect for travellers who want to chill out. According to booking.com, Legian has become increasingly popular with travellers in the last year. 3. London, England For anyone embarking on a Euro summer, London is a must-see destination for any keen traveller. There's something in London for everyone, from amazing museums and sprawling markets, to iconic landmarks and rich history. 2. Tokyo, Japan While tourism in Japan has surged in recent years, there’s a good reason why, as many travellers are flocking to the nation to experience its rich culture. On top of it being an affordable destination, the unique experience has Aussies heading to Japan in droves, with Tokyo seeing a 25 per cent search increase among Aussies in the last year. 1. Seminyak, Bali Unsurprisingly, a Bali destination has topped the list, as Seminyak offers luxury hotels and villas, high-end dining, and famous beach clubs. Located between Canggu and Kuta, Seminyak has long hosted thousands of tourists looking to escape the cold, with travellers and locals alike basking in the picturesque sunsets.

The sad state of Aussie ski resorts ahead of winter holiday season

Ski resorts in Australia have had to get creative ahead of the tourist-heavy ski season after a lack of snowfall, despite plunging temperatures. The ski season begins this year on the June long weekend, running alongside the King’s Birthday on June 8th. Despite expecting a huge influx of keen skiers, there has only been light flurries of snow so far, according to WeatherZone, which melt away quickly and don't settle on the ground for long. In order to accommodate the busy season, Thredbo has had to resort to using fake snow for people to ski on. Manufactured snow happens by combining pressurised air and water through a ‘snow gun’ that gets blasted out into the air. The most ideal time to create the fake snow is on clear nights with low humidity, as the higher the humidity the colder it needs to be to make the flurries. Several photos from ski.com.au's cameras have shown popular ski sites with a disappointing lack of snow, in scenes similar to last year's ski season. “No significant snowfalls are on the horizon for the mainland Australian ski resorts before the official King’s Birthday Long Weekend season opening,” Weatherzone reports. “Snow-making began on the weekend at several resorts and has continued into the working week in the cold dry, air in the wake of the cold front.” According to WeatherZone, high-pressure systems, which have brought constant rain to the east coast recently, have been blocking the snowfall.

Travel Trouble

"Can't WAIT to try this": Tradie's simple bin night hack

Taking the wheelie bins out and having to drag them back in is a chore that many dread, but one Aussie tradie has made life so much easier with his simple hack. Kyle Hume took to TikTok to share his simple yet effective trick to bring in two bins back from the curb at the same time, without having to wrangle two bins with both hands or make multiple trips. "I've been wheeling two bins my whole life until I noticed this," he shared. Hume's trick is to line up two bins in front of each other, resting the lid of the bin at the front on top of the bin at the back, and then closing the lid so it creates a makeshift hook that allows you to tip both bins back and wheel them in unison. <div class="embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important; width: 573px; max-width: 100%;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7360205539604696336&display_name=tiktok&url=https%3A%2F%2Fwww.tiktok.com%2F%40kylehume7%2Fvideo%2F7360205539604696336%3Flang%3Den&image=https%3A%2F%2Fp16-sign-sg.tiktokcdn.com%2Fobj%2Ftos-alisg-p-0037%2FoYPnEqGncBAAtH22Eli4AIzBQC4wEANEIsf1ki%3Fx-expires%3D1715479200%26x-signature%3Di%252BOzi1g942kcQ1F0%252FqQuNd7eiho%253D&key=59e3ae3acaa649a5a98672932445e203&type=text%2Fhtml&schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> Many Aussies were "flabbergasted" by the trick, taking to the comments to express their shock at the simple method. "I've learned more on TikTok about adulting than I ever did in school," one joked. "I have four bins - this is going to save my life," another added. "What? Are you kidding me?" a third exclaimed. However, not everyone was impressed with his method, with some saying that it wouldn't work and there is a risk of damaging the bins. "Guessing that green bin slipped over and split using this hack, lol," one wrote. "This seems awkward and clunky," another added. "Don't you have two arms?" a third wrote. Images: TikTok

Paris in spring, Bali in winter. How ‘bucket lists’ help cancer patients handle life and death

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/leah-williams-veazey-1223970">Leah Williams Veazey</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/alex-broom-121063">Alex Broom</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/katherine-kenny-318175">Katherine Kenny</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> In the 2007 film <a href="https://www.imdb.com/title/tt0825232/">The Bucket List</a> Jack Nicholson and Morgan Freeman play two main characters who respond to their terminal cancer diagnoses by rejecting experimental treatment. Instead, they go on a range of energetic, overseas escapades. Since then, the term “bucket list” – a list of experiences or achievements to complete before you “kick the bucket” or die – has become common. You can read articles listing <a href="https://www.cnbc.com/2023/01/11/cities-to-visit-before-you-die-according-to-50-travel-experts-and-only-one-is-in-the-us.html">the seven cities</a> you must visit before you die or <a href="https://www.qantas.com/travelinsider/en/trending/top-100-guide/best-things-to-do-and-see-in-australia-travel-bucket-list.html">the 100</a> Australian bucket-list travel experiences. <figure><iframe src="https://www.youtube.com/embed/UvdTpywTmQg?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> But there is a more serious side to the idea behind bucket lists. One of the key forms of suffering at the end of life <a href="https://onlinelibrary.wiley.com/doi/10.1002/pon.4821">is regret</a> for things left unsaid or undone. So bucket lists can serve as a form of insurance against this potential regret. The bucket-list search for adventure, memories and meaning takes on a life of its own with a diagnosis of life-limiting illness. In a <a href="https://journals.sagepub.com/doi/10.1177/14407833241251496">study</a> published this week, we spoke to 54 people living with cancer, and 28 of their friends and family. For many, a key bucket list item was travel. <h2>Why is travel so important?</h2> There are lots of reasons why travel plays such a central role in our ideas about a “life well-lived”. Travel is often linked to important <a href="https://doi.org/10.1016/j.annals.2003.10.005">life transitions</a>: the youthful gap year, the journey to self-discovery in the 2010 film <a href="https://www.imdb.com/title/tt0879870/">Eat Pray Love</a>, or the popular figure of the “<a href="https://theconversation.com/grey-nomad-lifestyle-provides-a-model-for-living-remotely-106074">grey nomad</a>”. The significance of travel is not merely in the destination, nor even in the journey. For many people, planning the travel is just as important. A cancer diagnosis affects people’s sense of control over their future, throwing into question their ability to write their own life story or plan their travel dreams. Mark, the recently retired husband of a woman with cancer, told us about their stalled travel plans: "We’re just in that part of our lives where we were going to jump in the caravan and do the big trip and all this sort of thing, and now [our plans are] on blocks in the shed." For others, a cancer diagnosis brought an urgent need to “tick things off” their bucket list. Asha, a woman living with breast cancer, told us she’d always been driven to “get things done” but the cancer diagnosis made this worse: "So, I had to do all the travel, I had to empty my bucket list now, which has kind of driven my partner round the bend." People’s travel dreams ranged from whale watching in Queensland to seeing polar bears in the Arctic, and from driving a caravan across the Nullarbor Plain to skiing in Switzerland. Nadia, who was 38 years old when we spoke to her, said travelling with her family had made important memories and given her a sense of vitality, despite her health struggles. She told us how being diagnosed with cancer had given her the chance to live her life at a younger age, rather than waiting for retirement: "In the last three years, I think I’ve lived more than a lot of 80-year-olds." <h2>But travel is expensive</h2> Of course, travel is expensive. It’s not by chance Nicholson’s character in The Bucket List is a billionaire. Some people we spoke to had emptied their savings, assuming they would no longer need to provide for aged care or retirement. Others had used insurance payouts or charity to make their bucket-list dreams come true. But not everyone can do this. Jim, a 60-year-old whose wife had been diagnosed with cancer, told us: "We’ve actually bought a new car and [been] talking about getting a new caravan […] But I’ve got to work. It’d be nice if there was a little money tree out the back but never mind." Not everyone’s bucket list items were expensive. Some chose to spend more time with loved ones, take up a new hobby or get a pet. Our study showed making plans to tick items off a list can give people a sense of self-determination and hope for the future. It was a way of exerting control in the face of an illness that can leave people feeling powerless. Asha said: "This disease is not going to control me. I am not going to sit still and do nothing. I want to go travel." <h2>Something we ‘ought’ to do?</h2> Bucket lists are also a symptom of a broader culture that emphasises conspicuous <a href="https://www.youtube.com/watch?v=JH_Pa1hOEVc">consumption</a> and <a href="https://productiveageinginstitute.org.au/">productivity</a>, even into the end of life. Indeed, people told us travelling could be exhausting, expensive and stressful, especially when they’re also living with the symptoms and side effects of treatment. Nevertheless, they felt travel was something they “<a href="https://doi.org/10.1080/14461242.2021.1918016">ought</a>” to do. Travel can be deeply meaningful, as our study found. But a life well-lived need not be extravagant or adventurous. Finding what is meaningful is a deeply personal journey. <hr /> Names of study participants mentioned in this article are pseudonyms.<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/225682/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/leah-williams-veazey-1223970">Leah Williams Veazey</a>, ARC DECRA Research Fellow, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/alex-broom-121063">Alex Broom</a>, Professor of Sociology & Director, Sydney Centre for Healthy Societies, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/katherine-kenny-318175">Katherine Kenny</a>, ARC DECRA Senior Research Fellow, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Caring

Dog care below freezing − how to keep your pet warm and safe from cold weather, road salt and more this winter

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a> Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can <a href="https://theconversation.com/is-winter-miserable-for-wildlife-108734">quickly turn chilly and dangerous</a> for people and pups alike. Winter brings some unique challenges for dog owners, since dogs still need activity and socialization during colder seasons. Studies have shown that dog owners are almost 50% less likely to walk their dogs <a href="https://doi.org/10.3390/ani11113302">when the weather gets cold</a>. Knowing the basics of winter safety is critical to maintaining a healthy lifestyle for your dog. I am an <a href="https://www.vetmed.ucdavis.edu/faculty/erik-olstad">assistant professor</a> at the University of California Davis School of Veterinary Medicine who weathered polar vortexes with my dog while living in Michigan early in my career. While I’ve since moved to sunny California, I’ve seen how quickly frigid temperatures can turn dangerous for pets. <h2>Breed and age differences</h2> Not all dogs have the same abilities to deal with cold weather. A short-coated dog like a Chihuahua is much more susceptible to the dangers of cold weather than a thick-coated husky. When the weather dips below 40 degrees Fahrenheit (4 degrees Celsius), the well-acclimated husky may be comfortable, whereas the Chihuahua would shiver and be at risk of hypothermia. Additionally, if your dog is used to warm weather, but you decide to move to a colder region, the dog will need time to acclimate to that colder weather, even if they have a thick coat. Age also affects cold-weather resilience. Puppies and elderly dogs can’t withstand the chill as well as other dogs, but every dog is unique – each may have individual health conditions or physical attributes that make them more or less resilient to cold weather. <h2>When is my dog too cold?</h2> Pet owners should be able to recognize the symptoms of a dog that is getting too cold. Dogs will shiver, and some may vocalize or whine. Dogs may resist putting their feet down on the cold ground, or burrow, or try to find warmth in their environment when they are uncomfortable. Just like people, <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">dogs can get frostbite</a>. And just like people, the signs can take days to appear, making it hard to assess them in the moment. The most common sites for frostbite in dogs are their ears and the tips of their tails. Some of the initial signs of frostbite are skin discoloring, turning paler than normal, or purple, gray or even black; red, blistered skin; swelling; pain at the site; <a href="https://www.britannica.com/science/ulcer">or ulceration</a>. Other <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">serious signs of hypothermia</a> include sluggishness or lethargy, and if you observe them, please visit your veterinarian immediately. A good rule to live by is if it is too cold for you, it is too cold for your dog. Getting your dog a <a href="https://www.cnn.com/cnn-underscored/pets/best-winter-dog-coats-jackets">sweater or jacket</a> and <a href="https://www.akc.org/expert-advice/vets-corner/protect-dogs-paws-snow-ice-salt/">paw covers</a> can provide them with protection from the elements and keep them comfortable. Veterinarians also recommend closely monitoring your dog and limiting their time outside when the temperature nears the freezing point or drops below it. <h2>Road salt dangers</h2> Road salt that treats ice on streets and sidewalks <a href="https://www.cbc.ca/news/canada/kitchener-waterloo/ice-salt-toxic-for-pets-1.5020088">can also harm dogs</a>. When dogs walk on the salt, the sharp, rough edges of the salt crystals can irritate the sensitive skin on their paws. Dogs will often lick their feet when they’re dirty, wet or irritated, and if they ingest any salt doing that, they may face GI upset, dehydration, kidney failure, seizures or even death. Even small amounts of pure salt can <a href="https://www.petpoisonhelpline.com/pet-tips/my-dog-ate-road-salt-will-they-be-okay/">disrupt critical body functions</a> in dogs. Some companies make pet-safe salt, but in public it can be hard to tell what type of salt is on the ground. After walking your dog, wash off their feet or boots. You can also keep their paw fur trimmed to prevent snow from balling up or salt collecting in the fur. Applying a thin layer of petroleum jelly or <a href="https://www.akc.org/expert-advice/lifestyle/how-to-make-your-own-paw-balm-for-winter/">paw pad balm</a> to the skin of the paw pads can also help protect your pet’s paws from irritation. <h2>Antifreeze risks</h2> <a href="https://www.britannica.com/science/antifreeze-chemical-substance">Antifreeze, or ethylene glycol</a>, is in most vehicles to prevent the fluids from freezing when it gets cold out. Some people pour antifreeze into their toilets when away from their home to prevent the water in the toilet from freezing. Antifreeze is an exceptionally dangerous chemical to dogs and cats, as it tastes sweet but can be deadly when ingested. If a pet ingests even a small amount of antifreeze, the substance causes a chemical cascade in their body that results in severe kidney damage. If left untreated, the pet may have <a href="https://www.petpoisonhelpline.com/pet-owner-blog/antifreeze-poisoning/">permanent kidney damage or die</a>. There are safer antifreeze options on the market that use ingredients other than ethylene glycol. If your dog ingests antifreeze, please see your veterinarian immediately for treatment. When temperatures dip below freezing, the best thing pet owners can do is keep the time spent outside as minimal as possible. Try some <a href="https://www.akc.org/expert-advice/lifestyle/great-indoor-games-to-play-with-your-dog/">indoor activities</a>, like hide-and-seek with low-calorie treats, fetch or even an interactive obstacle course. Food puzzles can also keep your dog mentally engaged during indoor time.
