Why do some people need less sleep than others?

<div class="theconversation-article-body"> <p>Have you ever noticed how some people bounce out of bed after just a few hours of sleep, while others can barely function without a solid eight hours?</p> <p>Take Margaret Thatcher, for example. The former British prime minister was known for sleeping <a href="https://www.bbc.com/news/magazine-22084671">just four hours a night</a>. She worked late, rose early, and seemed to thrive on little sleep.</p> <p>But for most of us, that kind of sleep schedule would be disastrous. We’d be groggy, unfocused, and reaching for sugary snacks and caffeinated drinks by mid-morning.</p> <p>So why do some people seem to need less sleep than others? It’s a question that’s fascinated scientists for years. Here’s what we know so far.</p> <h2>Natural short sleepers</h2> <p>There is a small group of people who don’t need much sleep. We call them <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6879540/">natural short sleepers</a>. They can function perfectly well on just four to six hours of sleep each night, often for their entire lives.</p> <p>Generally they <a href="https://academic.oup.com/sleep/article/44/Supplement_2/A154/6260529">don’t feel tired</a>, they don’t nap, and they don’t suffer the usual negative consequences of sleep deprivation. Scientists call this the natural short sleep phenotype – a biological trait that allows people to get all the benefits of sleep in less time.</p> <p>In 2010 researchers discovered genetic mutations that help explain this phenomenon. Natural short sleepers carry rare variants <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2884988/">in certain genes</a>, which seem to make their sleep more efficient.</p> <p>More recently, a <a href="https://www.pnas.org/doi/epub/10.1073/pnas.2500356122">2025 study</a> assessed a woman in her 70s with one of these rare mutations. Despite sleeping just six hours a night for most of her life, she remained physically healthy, mentally sharp, and led a full, active life. Her body, it seems, was simply wired to need less sleep.</p> <p>We’re still learning about how common these genetic mutations are and why they occur.</p> <h2>Not everyone who sleeps less is a natural short sleeper</h2> <p>But here’s the catch: most people who think they’re natural short sleepers aren’t. They’re just chronically sleep-deprived. Often, their short sleep is due to long work hours, social commitments, or a belief sleeping less is a sign of strength or productivity.</p> <p>In today’s hustle culture, it’s common to hear people boast about getting by on only a few hours of sleep. But for the average person, that’s not sustainable.</p> <p>The effects of short sleep build up over time, creating what’s known as a “sleep debt”. This <a href="https://www.sciencedirect.com/science/article/pii/S0149763417301641">can lead to</a> poor concentration, mood swings, micro-sleeps (brief lapses into sleep), reduced performance and even <a href="https://www.sciencedirect.com/science/article/pii/S1389945716301381">long-term health risks</a>. For example, short sleep has been linked to an increased risk of obesity, diabetes, high blood pressure and cardiovascular disease (heart disease and stroke).</p> <h2>The weekend catch-up dilemma</h2> <p>To make up for lost sleep during the week, many people try to “catch up” on weekends.</p> <p>This can help repay some of the sleep debt that has accumulated in the short term. Research <a href="https://www.sciencedirect.com/science/article/pii/S2352721823001663?via%3Dihub">suggests</a> getting one to two extra hours of sleep on the weekend or taking naps when possible may help reduce the negative effects of short sleep.</p> <p>However, it’s not a perfect fix. Weekend catch-up sleep and naps may not fully resolve sleep debt. The topic remains one of ongoing scientific debate.</p> <p>A recent <a href="https://academic.oup.com/sleep/article/47/11/zsae135/7696120">large study</a> suggested weekend catch-up sleep may not offset the cardiovascular risks associated with chronic short sleep.</p> <p>What’s more, large swings in sleep timing can disrupt your body’s <a href="https://www.nature.com/articles/s41598-017-03171-4">internal clock</a>, and sleeping in too much on weekends may make it harder to fall asleep on Sunday night, which can mean starting the working week less rested.</p> <p>Increasing evidence indicates <a href="https://academic.oup.com/sleep/article/47/1/zsad253/7280269">repeated cycles of irregular sleep</a> may have an important influence on general health and the risk of early death, potentially even more so than how long we sleep for.</p> <p>Ultimately, while moderate catch-up sleep might offer some benefits, it’s no substitute for consistent, high-quality sleep throughout the week. That said, maintaining such regularity can be particularly challenging for people with non-traditional schedules, such as shift workers.</p> <h2>So, was Thatcher a true natural short sleeper?</h2> <p>It’s hard to say. Some reports suggest <a href="https://www.theguardian.com/lifeandstyle/2021/aug/27/from-aristotle-to-einstein-a-brief-history-of-power-nappers">she napped during the day</a> in the back of a car between meetings. That could mean she was simply sleep-deprived and compensating for an accumulated sleep debt when she could.</p> <p>Separate to whether someone is a natural short sleeper, there are a range of other reasons people may need more or less sleep than others. Factors <a href="https://www.sleephealthfoundation.org.au/sleep-topics/how-much-sleep-do-you-really-need">such as age</a> and underlying health conditions can significantly influence sleep requirements.</p> <p>For example, older adults often experience changes in their circadian rhythms and are more likely to suffer from fragmented sleep due to conditions <a href="https://link.springer.com/article/10.1007/s00702-019-02067-z">such as arthritis</a> or <a href="https://link.springer.com/article/10.1007/s11886-023-01939-x">cardiovascular disease</a>.</p> <p>Sleep needs vary from person to person, and while a lucky few can thrive on less, most of us need <a href="https://www.sleephealthfoundation.org.au/sleep-topics/how-much-sleep-do-you-really-need">seven to nine hours</a> a night to feel and function our best. If you’re regularly skimping on sleep and relying on weekends to catch up, it might be time to rethink your routine. After all, sleep isn’t a luxury – it’s a biological necessity.<!-- Below is The Conversation's page counter tag.

Why do some people get a curved back as they age and what can we do to avoid it?

<div class="theconversation-article-body"> <p>As we age, it’s common to notice posture changes: shoulders rounding, head leaning forward, back starting to curve. You might associate this with older adults and wonder: will this happen to me? Can I prevent it?</p> <p>It’s sometimes called “hunchback” or “roundback”, but the medical term for a curved back is kyphosis.</p> <p>When the curve is beyond what’s considered normal (greater than 40 degrees), we refer to this as hyperkyphosis. In more <a href="https://www.jospt.org/doi/10.2519/jospt.2010.3099#_i12:%7E:text=gold%2Dstandard%20radiograph.-,Clinical%20Consequences%20of%20Hyperkyphosis,-Functional%20Limitations">severe cases</a>, it may lead to pain, reduced mobility and physical function, or lower quality of life.</p> <p>Here’s how it happens, and how to reduce your risk.</p> <h2>What causes a curved back?</h2> <p>A healthy spine has an elongated s-shape, so a curve in the upper spine is completely normal.</p> <p>But when that curve becomes exaggerated and fixed (meaning you can’t stand up straight even if you try), it can signal a problem.</p> <p>One common cause of a curved back is poor posture. This type, called postural kyphosis, usually develops over time due to muscle imbalances, particularly in younger people who spend hours:</p> <ul> <li>hunched over a desk</li> <li>slouched in a chair, or</li> <li>looking down at a phone.</li> </ul> <p>Fortunately, this kind of curved back is often reversible with the right exercises, stretches and posture awareness.</p> <p>Older adults often develop a curved back, known as age-related kyphosis or hyperkyphosis.</p> <p>This is usually due to wear and tear in the spine, including vertebral compression fractures, which are tiny cracks in the bones of the spine (vertebrae).</p> <p>These cracks are most often caused by osteoporosis, a condition that makes bones more fragile with age.</p> <p>In these cases, it’s not just bad posture – it’s a structural change in the spine.</p> <h2>How can you tell the difference?</h2> <p>Signs of age-related hyperkyphosis include:</p> <ul> <li>your back curves even when you try to stand up straight</li> <li>back pain or stiffness</li> <li>a loss of height (anything greater than 3-4 centimetres compared to your peak adult height may be considered outside of “normal” ageing).</li> </ul> <p>Other causes of a curved back include:</p> <ul> <li><a href="https://pubmed.ncbi.nlm.nih.gov/30407981/">Scheuermann’s kyphosis</a> (which often develops during adolescence when the bones in the spine grow unevenly, leading to a forward curve in the upper back)</li> <li><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4347150/">congenital kyphosis</a> (a rare condition present from birth, caused by improper formation of the spinal bones. It can result in a more severe, fixed curve that worsens as a child grows)</li> <li>scoliosis (where the spine curves sideways into a c- or s-shape when viewed from behind), and</li> <li>lordosis (an excessive inward curve in the lower back, when viewed from the side).</li> </ul> <p>In addition to these structural conditions, arthritis, and in rare cases, spinal injuries or infections, can also play a role.</p> <h2>Should I see a doctor about my curved back?</h2> <p>Yes, especially if you’ve noticed a curve developing, have ongoing back pain, or have lost height over time.</p> <p>These can be signs of vertebral fractures, which can occur in the absence of an obvious injury, and are often painless.</p> <p>While one in five older adults have a vertebral fracture, as many as two-thirds of these fractures are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0002934315010128?casa_token=DzXngmS6GIoAAAAA:3ub0V4PuHbKjrqO9xYDo8vx2m9k6tbOtmz4yIVzkQvH-VylhgO_KnKaTYDLXpiHc9_4Jz0iNdQ">not diagnosed and treated</a>.</p> <p>In Australia, the Royal Australian College of General Practitioners and Healthy Bones Australia <a href="https://healthybonesaustralia.org.au/wp-content/uploads/2022/12/oa-racgp-osteoporosis-clinical-guidelines-2nd-ed.pdf">recommend</a> a spine x-ray for:</p> <ul> <li>people with kyphosis</li> <li>height loss equal to or more than 3 centimetres, or</li> <li>unexplained back pain.</li> </ul> <h2>What can I do to reduce my risk?</h2> <p>If you’re young or middle-aged, the habits you build today matter.</p> <p>The best way to prevent a curved back is to keep your bones strong, muscles active, and posture in check. That means:</p> <ul> <li>doing regular resistance training, especially targeting upper back muscles</li> <li>staying physically active, aiming for at least <a href="https://www.who.int/initiatives/behealthy/physical-activity">150 minutes per week</a></li> <li>getting enough protein, calcium, and vitamin D to support bone and muscle health</li> <li>avoiding smoking and limiting alcohol to reduce risk factors that worsen bone density and overall wellbeing</li> </ul> <p>Pay attention to your posture while sitting and standing. Position your head over your shoulders and shoulders over your hips. This reduces strain on your spine.</p> <h2>What exercises help prevent and manage a curved back?</h2> <p>Focus on <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5112023/">exercises that strengthen the muscles</a> that support an upright posture, particularly the upper back and core, while improving mobility in the chest and shoulders.</p> <p>In general, you want to prioritise extension-based movements. These involve straightening or lifting the spine and pulling the shoulders back.</p> <p>Repeated forward-bending (or flexion) movements may make things worse, especially in people with osteoporosis or spinal fractures.</p> <p>Good exercises include:</p> <ul> <li>back extensions (gently lift your chest off the floor while lying face down)</li> <li>resistance exercises targeting the muscles between your shoulder blades</li> <li>weight-bearing activities (such as brisk walking, jogging, stair climbing, or dancing) to keep bones strong and support overall fitness</li> <li>stretching your chest and hip flexors to open your posture and relieve tightness.</li> </ul> <p>Flexibility and balance training (such as yoga and pilates) can be <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3700806/">beneficial</a>, particularly for posture awareness, balance, and mobility. But <a href="https://pubmed.ncbi.nlm.nih.gov/31034509/">research</a> increasingly supports muscle strengthening as the cornerstone of prevention and management.</p> <p>Muscle strengthening exercises, such as weight lifting or resistance training, reduces spinal curvature while enhancing muscle and bone mass.</p> <p>If you suspect you have kyphosis or already have osteoporosis or a vertebral fracture, consult a health professional before starting an exercise program. There may be some activities to avoid.</p> <h2>Can a curved back be reversed?</h2> <p>If it’s caused by poor posture and muscle weakness, then yes, it’s possible.</p> <p>But if it’s caused by bone changes, especially vertebral fractures, then full reversal is unlikely. However, treatment can reduce pain, improve function, and slow further progression.</p> <p>Protecting your posture isn’t just about appearance. It’s about staying strong, mobile and independent as you age.<!-- Below is The Conversation's page counter tag.

It’s almost winter. Why is Australia still so hot?

<div class="theconversation-article-body"> <p>This year, for many Australians, it feels like summer never left. The sunny days and warm nights have continued well into autumn. Even now, in May, it’s still unusually warm.</p> <p>Much of the southern half of the continent is experiencing both unseasonable warmth and dry conditions. This is linked to persistent high atmospheric pressure (called “blocking”) to the south and southeast of Australia.</p> <p>While temperatures will fall across southern Australia as we approach the winter solstice, early indications are that this winter will be a warm one. Rainfall predictions are less certain.</p> <p>The extra warmth we’ve experienced raises obvious questions about the influence of human-caused climate change. The warming signal is clear and it’s a sign of things to come.</p> <h2>A warm and dry autumn for many</h2> <p><a href="http://www.bom.gov.au/jsp/awap/temp/index.jsp?colour=colour&amp;time=latest&amp;step=1&amp;map=meananom&amp;period=month&amp;area=nat">March</a> and <a href="http://www.bom.gov.au/jsp/awap/temp/index.jsp?colour=colour&amp;time=latest&amp;step=0&amp;map=meananom&amp;period=month&amp;area=nat">April</a> brought unseasonal heat to much of Australia.</p> <p>March was widely hot, with temperatures several degrees above normal across much of the country.

Western Tasmania is also suffering from a severe lack of rainfall since the start of autumn, although welcome rain fell in the past week.</p> <p>And it’s not just on land that unusual heat has been observed. The seas around Australia have been warmer than normal, causing severe coral bleaching to <a href="https://theconversation.com/synchronised-bleaching-ningaloo-and-the-great-barrier-reef-are-bleaching-in-unison-for-the-first-time-252906">the west and east</a> of the continent, <a href="https://www.epa.sa.gov.au/environmental_info/water_quality/harmful-algal-blooms">harmful algal blooms</a> and other ecosystem disruptions.</p> <h2>Blocking highs largely to blame</h2> <p>A high pressure system has dominated over the south and southeast of Australia over the past few months.</p> <p>High pressure in the Tasman Sea can sometimes get stuck there for a few days. This leads to what’s known as “blocking”, when the usual passage of weather systems moving from west to east is obstructed. This can lock in weather patterns for several days or even a week.</p> <p>Repeated blocking occurred this autumn. As winds move anticlockwise around high pressure systems in the Southern Hemisphere, blocking highs in the Tasman Sea can bring moist, onshore winds to the New South Wales and Queensland coasts, increasing rainfall. But such high pressure systems also bring drier conditions for the interior of the southeast and much of Victoria and South Australia.</p> <p>Often, these high pressure systems also bring northerly winds to Victoria, and this can cause warmer conditions across much of the state.</p> <p>High pressure systems also tend to bring more clear and sunny conditions, which increases daytime temperatures in particular. Air in high pressure systems moves down towards the surface and this process causes warming, too.</p> <p>Australia sits between the Pacific and Indian Oceans and is subject to their variability, so we often look there to help explain what’s happening with Australia’s climate. In autumn though, our climate influences, such as the El Niño-Southern Oscillation and the Indian Ocean Dipole, are less active and have weaker relationships with Australian climate than at other times of year. Neither of these climate influences is <a href="http://www.bom.gov.au/climate/outlooks/#/overview/influences">in a strong phase</a> at the moment.</p> <h2>A warm winter on the cards</h2> <p>One big question is how long the heat will last. In parts of southeast Australia, including <a href="http://www.bom.gov.au/jsp/ncc/cdio/cvg/av?p_stn_num=086071&amp;p_prim_element_index=0&amp;p_display_type=statGraph&amp;period_of_avg=ALL&amp;normals_years=allYearOfData&amp;staticPage=">Melbourne</a>, average temperatures drop quickly at this time of year as we approach the winter solstice.</p> <p>However, the seasonal outlook from the Bureau of Meteorology points to a high likelihood of a relatively <a href="http://www.bom.gov.au/climate/outlooks/#/temperature/maximum/median/seasonal/0">warm winter</a>.</p> <p>Australians rarely escape having a winter without any significant cold spells, but the long-range forecast suggests we should anticipate above-normal temperatures on average. Both daytime maximum temperatures and nighttime minimum temperatures are expected to be above average generally this winter.</p> <figure><iframe src="https://www.youtube.com/embed/Y5NIa7X2H-s?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Climate and water long-range forecast, issued 1 May 2025 (Bureau of Meteorology)</span></figcaption></figure> <h2>Global warming is here</h2> <p>The elephant in the room is climate change. Human-caused climate change is increasing autumn temperatures and the frequency of late season heat events. As greenhouse gas emissions continue at a <a href="https://theconversation.com/global-carbon-emissions-inch-upwards-in-2024-despite-progress-on-evs-renewables-and-deforestation-243133">record pace</a>, expect continued warming and a greater chance of autumn heatwaves in future.</p> <p>The effect of climate change on rainfall is less clear though. For the vast majority of Australia, there is <a href="https://interactive-atlas.ipcc.ch/regional-information">high uncertainty</a> as to whether autumn will become wetter or drier as the world warms.<!-- Below is The Conversation's page counter tag.

Why are political parties allowed to send spam texts? And how can we make them stop?

<div class="theconversation-article-body"> <p>Another election, another wave of unsolicited political texts. Over this campaign, our digital mailboxes have been stuffed with a slew of political appeals and promises, many from the new party Trumpet of Patriots (backed by Clive Palmer, a <a href="https://www.abc.net.au/news/2019-01-11/clive-palmer-united-australia-party-unsolicited-text-messages/10709106">veteran</a> of the mass text campaign).</p> <p>The practice isn’t new, and it’s totally legal under current laws. It’s also non-partisan. Campaigns of all stripes have partaken. Behold, the Liberal Party’s <a href="https://www.sbs.com.au/news/article/liberal-party-defends-sending-text-messages-to-voters-on-asylum-seeker-boat-intercepts/mmqwk5508">last-minute SMS</a> to voters about asylum seekers before the 2022 federal election, or Labor’s controversial “<a href="https://www.smh.com.au/politics/federal/federal-election-2016-shorten-confirms-labor-sent-mediscare-text-20160705-gpzasl.html">Mediscare</a>” text before the 2016 poll. Despite multiple cycles of criticism, these tactics remain a persistent feature of Australian election campaigns.</p> <p>A recent proposal to update decades-old rules could help change things – if a government would put it into practice.</p> <h2>What does the law say about political spam?</h2> <p>Several laws regulate spam and data collection in Australia.</p> <p>First, there is the Spam Act. This legislation requires that organisations obtain our consent before sending us marketing emails, SMSs and instant messages. The unsubscribe links you see at the bottom of spam emails? Those are mandated by the Spam Act.</p> <p>Second, the Do Not Call Register (DNCR) Act. This Act establishes a “do not call” register, managed by the <a href="https://www.acma.gov.au/say-no-to-telemarketers">Australian Communications and Media Authority</a> (ACMA), which individuals can join to opt out of telemarketing calls.</p> <p>Finally, there is the Privacy Act, which governs how organisations collect, use and disclose our personal information. Among other things, the Privacy Act requires that organisations tell us when and why they are collecting our personal information, and the purposes for which they intend to use it. It restricts organisations from re-purposing personal information collected for a particular purpose, unless an exception applies.</p> <p>This trio of laws was designed to offer relief from unsolicited, unwanted direct marketing. It does not, however, stop the deluge of political spam at election time due to broad political exemptions sewn into the legislation decades ago.</p> <p>The Spam Act and DNCR Act apply to marketing for goods and services but not election policies and promises, while the Privacy Act contains a <a href="https://classic.austlii.edu.au/au/journals/UNSWLawJl/2021/21.html#fn13">carve-out</a> for political parties, representatives and their contractors.</p> <p>The upshot is that their campaigns are free to spam and target voters at will. Their only obligation is to disclose who authorised the message.</p> <h2>How do political campaigns get our information?</h2> <p>Secrecy about the nature and extent of campaign data operations, enabled by the exemptions, makes it difficult to pinpoint precisely where a campaign might have obtained your data from.</p> <p>There are, however, a number of ways political campaigns can acquire our information.</p> <p>One source is the electoral roll (though not for phone numbers, as the Australian Electoral Commission <a href="https://x.com/AusElectoralCom/status/1434752533294194692">often points out</a>). Incumbent candidates might build on this with information they obtain through contact with constituents which, thanks to the exemptions, they’re allowed to re-purpose for campaigning at election time.</p> <p>Another source is data brokers – firms which harvest, analyse and sell large quantities of data and profiles.</p> <p>We know the major parties have long maintained voter databases to support their targeting efforts, which have become <a href="https://www.abc.net.au/news/2022-05-19/behind-liberal-labor-data-arms-race-this-election/101074696">increasingly sophisticated</a> over the years.</p> <p>Other outfits might take more haphazard approaches – former MP <a href="https://www.smh.com.au/politics/federal/united-australia-party-leader-craig-kelly-defends-spam-messages-20210829-p58mv7.html">Craig Kelly</a>, for example, claimed to use software to randomly generate numbers for his texting campaign in 2021.</p> <h2>What can be done?</h2> <p>Unwanted campaign texts are not only irritating to some. They can be misleading.</p> <p>This year, there have been <a href="https://www.abc.net.au/news/2025-04-17/monique-ryan-polling-amelia-hamer-trust-fund-kooyong/105185290">reports</a> of “push polling” texts (pseudo surveys meant to persuade rather than gauge voter options) in the marginal seat of Kooyong. The AEC has <a href="https://www.aec.gov.au/media/2025/03-31a.htm">warned</a> about misleading postal vote applications being issued by parties via SMS.</p> <figure class="align-right zoomable"><a href="https://images.theconversation.com/files/664617/original/file-20250429-74-yothae.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/664617/original/file-20250429-74-yothae.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=237&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/664617/original/file-20250429-74-yothae.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=738&fit=crop&dpr=1 600w, https://images.theconversation.com/files/664617/original/file-20250429-74-yothae.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=738&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/664617/original/file-20250429-74-yothae.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=738&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/664617/original/file-20250429-74-yothae.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=927&fit=crop&dpr=1 754w, https://images.theconversation.com/files/664617/original/file-20250429-74-yothae.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=927&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/664617/original/file-20250429-74-yothae.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=927&fit=crop&dpr=3 2262w" alt="Screenshot of a text message from Trumpet of Patriots." /></a><figcaption><span class="caption">This election campaign has seen a flood of texts from Trumpet of Patriots, among others.</span> <span class="attribution"><span class="source">The Conversation</span>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></span></figcaption></figure> <p>Generative AI is hastening the ability to produce misleading content, cheaply and at scale, which can be quickly pushed out across an array of online social and instant messaging services.</p> <p>In short, annoying texts are just one visible symptom of a wider vulnerability created by the political exemptions.</p> <p>The basic argument for the political exemptions is to facilitate freedom of political communication, which is protected by the Constitution. As the High Court has said, that freedom is necessary to support informed electoral choice. It does not, however, guarantee speakers a <a href="http://www6.austlii.edu.au/cgi-bin/viewdoc/au/cases/cth/HCA/2019/11.html">captive audience</a>.</p> <p>In 2022, the Attorney-General’s Department <a href="https://www.ag.gov.au/sites/default/files/2023-02/privacy-act-review-report_0.pdf">proposed</a> narrowing the political exemptions, as part of a suite of updates to the Privacy Act. Per the proposal, parties and representatives would need to be more transparent about their data operations, provide voters with an option to unsubscribe from targeted ads, refrain from targeting voters based on “sensitive information”, and handle data in a “fair and reasonable” manner.</p> <p>The changes would be an overdue but welcome step, recognising the <a href="https://bridges.monash.edu/articles/journal_contribution/Conceptualising_Voter_Privacy_in_the_Age_of_Data-Driven_Political_Campaigning/27330276?file=50073381">essential role</a> of voter privacy in a functioning democratic system.</p> <p>Unfortunately, the government has not committed to taking up the proposal.</p> <p>A bipartisan lack of support is likely the biggest obstacle, even as the gap created by the political exemptions widens, and its rationale becomes flimsier, with each election cycle.<!-- Below is The Conversation's page counter tag.

Our ancestors didn’t eat 3 meals a day. So why do we?

<div class="theconversation-article-body"> <p>Pop quiz: name the world’s most famous trio? If you’re a foodie, then your answer might have been breakfast, lunch and dinner. It’s an almost universally accepted trinity – particularly in the Western world.</p> <p>But how did it come about?</p> <h2>The first meals</h2> <p><a href="https://theconversation.com/when-did-we-become-fully-human-what-fossils-and-dna-tell-us-about-the-evolution-of-modern-intelligence-143717#:%7E:text=Fossils%20and%20DNA%20suggest%20people,%3A%2050%2C000%2D65%2C000%20years%20ago">Early humans</a> were nomadic. Forming small communities, they would travel with the seasons, following local food sources.</p> <p>While we can only guess what daily mealtimes rhythms looked like, evidence dating back <a href="https://global.oup.com/academic/product/feast-9780199209019?cc=nz&lang=en&">30,000 years</a> from the South Moravia region, Czech Republic, shows people visited specific settlements time and again. They gathered around hearths, cooking and sharing food: the first signs of human “commensality”, the practice of eating together.</p> <p>One of the best-preserved hunter-gatherer sites we’ve found is <a href="https://global.oup.com/academic/product/feast-9780199209019?cc=nz&lang=en&">Ohalo II</a> – located on the shores of the modern-day Sea of Galilee (also called Lake Tiberias or Lake Kinneret) in Israel, and dating back some 23,000 years.</p> <p>In addition to several small dwellings with hearths, it provides evidence of diverse food sources, including more than 140 types of seeds and nuts, and various birds, fish and mammals.</p> <p>The development of <a href="https://education.nationalgeographic.org/resource/development-agriculture/">agricultural knowledge</a> some 12,000 years ago gave rise to permanent settlements. The earliest were in the Levant region (across modern-day Iraq, southwestern Iran and eastern Turkey), in an area called the “Fertile Crescent”.</p> <p>Permanent agriculture led to the production of a <a href="https://www.nationalgeographic.com/foodfeatures/evolution-of-diet/">surplus of food</a>. The ability to stay in one place with food on-hand meant the time it took to cook no longer mattered as much.</p> <p>It quickly became common to eat one <a href="https://www.bloomsbury.com/us/history-of-the-world-in-6-glasses-9780802718594/">light meal</a> early in the day, followed by a larger <a href="https://global.oup.com/academic/product/feast-9780199209019?cc=nz&lang=en&">hearth-prepared meal</a> later on. The specific timings would have varied between groups.</p> <h2>Eating together as a rule</h2> <p>The communal nature of foraging and hunting, and later farming, meant humans almost always ate their meals in the <a href="https://doi.org/10.1525/gfc.2009.9.3.42">company of others</a>. In the ancient city-state of Sparta, in the <a href="https://doi.org/10.2307/293895">4th century BCE</a>, these practices were codified as common main meals called <a href="https://doi.org/10.1525/gfc.2017.17.2.51"><em>syssitia</em></a> (meaning “eating together”).</p> <p>These meals were consumed at the end of the day in communal dining halls. Food was served by young boys to tables of 15 or so men who lived together and fought in the same <a href="https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0063%3Aalphabetic+letter%3DS%3Aentry+group%3D5%3Aentry%3Dsyssitia-cn">military division</a>. The men gradually shared generational knowledge with the young boys, who themselves would join the tables by age 20.</p> <p>In the 5th century BCE, Greek historian Herodotus <a href="https://www.penguin.co.nz/books/the-histories-9780140455397">wrote about</a> how <em>syssitia</em> evolved from a Spartan military practice to having deep political meaning in society. Similarly, <a href="https://www.penguin.co.nz/books/the-republic-9780140455113">Plato</a> <a href="https://www.penguin.co.nz/books/the-laws-9780140449846">wrote</a> common meals were an integral component of civil society, and that missing a meal without good reason was a civic offence.</p> <p>By dining in <a href="https://doi.org/10.2307/293895">full view</a> of the rest of society, citizens were compelled to maintain self-discipline. Mealtime was also an opportunity for social linkage, and <a href="https://doi.org/10.1525/gfc.2017.17.2.51">important discussions</a> ranging from business deals to politics.</p> <p>The eating habits of Spartan women are missing in the texts, although it is implied they <a href="https://doi.org/10.1525/gfc.2017.17.2.51">ate at home</a>.</p> <h2>Bunches of lunches</h2> <p>Counter to the tough Spartan way of life, the Romans enjoyed their main meal, <a href="https://www.press.jhu.edu/books/title/1550/everyday-life-ancient-rome?srsltid=AfmBOooVPsJL24HR9woTdVNQwEG1uCU7q0k7r2beD-KD13m0KX-l1dSY"><em>cena</em></a>, earlier in the day, followed by a lighter meal just before bed.</p> <p>The northern European tribes tended towards two larger meals per day, as more <a href="https://doi.org/10.1002/ajpa.23071">sustenance</a> is required in colder climes. To the Vikings, these meals were known as <a href="https://www.historyonthenet.com/what-did-vikings-eat"><em>dagmal</em> and <em>nattmal</em></a>, or day meal and night meal. <em>Nattmal</em> was the cooked evening meal, while <em>dagmal</em> usually consisted of leftover <em>nattmal</em> with the addition of bread and beer or mead.</p> <p>In Australia, evidence suggests Aboriginal peoples tended toward a <a href="https://www.tandfonline.com/doi/full/10.1080/03122417.2022.2089395">daily single meal</a>, which aligns with the predominant method of cookery: slow-cooking with hot coals or rocks in an <a href="https://doi.org/10.1080/03122417.2022.2089395">earth oven</a>. This underground oven, used by Aboriginal and also Torres Strait Islander communities, was referred to as a <a href="https://www.facebook.com/watch/?v=745326709638881&t=0"><em>kup murri</em></a> or <a href="https://www.sbs.com.au/food/the-cook-up-with-adam-liaw/recipe/slow-cooker-kap-mauri/lfza7eqs4"><em>kap mauri</em></a> by some groups.</p> <p>This is similar to other Indigenous preparations throughout the Pacific, such as the New Zealand Māori <a href="https://doi.org/10.1080/15528014.2024.2381305"><em>hāngī</em></a>, Hawaiian <a href="https://www.jstor.org/stable/20707103?seq=1"><em>imu</em></a>, Fijian <a href="https://www.proquest.com/docview/1021389307?accountid=8440&parentSessionId=605Pt1iTclBEC77VSlZvrnxxY%2Bdc7e%2Bx9pT4MgRLPqQ%3D&sourcetype=Dissertations%20&%20Theses"><em>lovo</em></a>, and even the Mayan <a href="https://doi.org/10.1007/s12231-012-9207-2"><em>píib</em></a>.</p> <p>The once-daily meal would have been supplemented with snacks throughout the day.</p> <h2>Three’s the magic number</h2> <p>The timing of meals was heavily influenced by class structure, local climate and people’s <a href="https://www.wiley.com/en-us/Cuisine+and+Culture%3A+A+History+of+Food+and+People%2C+3rd+Edition-p-9780470403716">daily activities</a>. Practicality also played a part. Without reliable lighting, meals had to be prepared and eaten before dark. In settled parts of Northern Europe, this could be as early as 3pm.</p> <p>So how did we go from one or two main meals, to three? The answer may lie with the British Royal Navy.</p> <p>Since its inception in the 16th century, the navy served <a href="https://www.historyhit.com/what-did-sailors-in-the-georgian-royal-navy-eat/">three regular meals</a> to align with the shipboard routine. This included a simple breakfast of ship’s biscuits, lunch as the main meal, and dinner as more of a light supper.</p> <p>Some sources suggest the term “<a href="https://www.grammar-monster.com/sayings_proverbs/square_meal.htm">square meal</a>” may have come from the square wooden trays meals were served in.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=455&fit=crop&dpr=1 600w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=455&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=455&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=572&fit=crop&dpr=1 754w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=572&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=572&fit=crop&dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Initially, sailors recieved a daily gallon of beer with meals.

Financial markets are tanking. Here’s why it’s best not to panic

<div class="theconversation-article-body"> <p>Financial markets around the world have been slammed by the Trump adminstration’s sweeping tariffs on its trading partners, and China’s swift retaliation.</p> <p>Share markets have posted their biggest declines since the COVID pandemic hit in 2020, as fears of US recession surged. Iron ore, copper, oil, gold and the Australian dollar have all tumbled.</p> <p>On Wall Street, <a href="https://www.reuters.com/markets/sp-500-loses-24-trillion-market-value-biggest-one-day-loss-since-2020-2025-04-03/">leading indices</a> have fallen around 10% since the tariffs were announced, while the tech-heavy Nasdaq is down 20% from its recent peak. European and Asian markets have also slumped.</p> <p>In Australia, the key S&amp;P/ASX 200 slid another 4.2% on Monday to levels last seen in December 2023, taking its three-day losses since the announcement to more than 7%.</p> <hr /> <p><iframe id="AJ2rZ" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/AJ2rZ/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <hr /> <h2>Why are markets reacting so badly?</h2> <p>Financial markets reacted so negatively because the tariffs were much larger than expected. They represent the <a href="https://www.abc.net.au/news/2025-04-05/trump-tariffs-upend-80-year-old-world-economic-order/105139464">biggest upheaval</a> in global trade in 80 years.</p> <p>Many traders were hoping the tariffs would be used mainly as a bargaining tool. <a href="https://finance.yahoo.com/news/live/trump-tariffs-live-updates-trump-digs-in-says-markets-may-have-to-take-medicine-as-stock-futures-plunge-191201959.html">But comments</a> by US President Donald Trump that markets may need to “take medicine” seem to suggest otherwise.</p> <p>The tariffs are expected to weaken economic growth in the US as consumers pare back spending on more expensive imports, while businesses shelve investment plans. Leading US bank JP Morgan has put the <a href="https://www.reuters.com/markets/jpmorgan-lifts-global-recession-odds-60-us-tariffs-stoke-fears-2025-04-04/">chance of a US recession</a> as high as 60%.</p> <p>This comes at a time when the US economy was already looking fragile. The highly regarded GDPNow model developed by the <a href="https://www.atlantafed.org/cqer/research/gdpnow">Atlanta Federal Reserve Bank</a> indicates US March quarter GDP will fall 2.8%, and that was before the tariff announcement.</p> <h2>Worries about global growth</h2> <p>Fears of a recession in the United States and the potential for a global downturn has led to a broad sell-off in commodity prices, including iron ore, copper and oil. Further, the Australian dollar, which is seen as a barometer for risk, has <a href="https://wise.com/au/currency-converter/currencies/aud-australian-dollar">fallen below 60 US cents</a> in local trading – its lowest level since 2009.</p> <p>While the direct impact of tariffs on Australia is expected to be modest (with around 6% of our exports going to US), the indirect impact could be substantial. China, Japan and South Korea together take more than 50% of Australia’s exports, and all have been hit with significantly higher tariffs.</p> <p>Treasurer Jim Chalmers said on Monday that the direct impact on the Australian economy would be “<a href="https://www.abc.net.au/news/2025-04-07/asx-markets-business-news-live-updates/105144276">manageable</a>”.</p> <p>The full effect on Australia will depend on how other countries respond, and whether we can redirect trade to other markets.</p> <p>The rapid decline in the Australian dollar will help offset some of the negative effects associated with a global downturn and the fall in commodity prices.</p> <p>We can also expect some interest-rate relief. Economists are now predicting <a href="https://www.afr.com/markets/debt-markets/traders-expect-up-to-five-rba-rate-cuts-amid-market-turmoil-this-year-20250407-p5lpo0">three further interest rate cuts</a> by the Reserve Bank, starting in May. This brings economists into line with financial market forecasts.</p> <h2>Hang in there, markets will recover</h2> <p>Watching equity markets tumble so dramatically can be unsettling for any investor. However, it is important to note that equity markets have experienced many downturns over the past 125 years due to wars, pandemics, financial crises and recessions. But these market impacts have generally been temporary.</p> <hr /> <p><iframe id="lsNFF" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/lsNFF/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <hr /> <p>History suggests that over the long term, equity prices continue to rise, supported by growing economies and rising incomes.</p> <p>The key thing for investors to remember is to not panic. Now is not the time to decide to switch your superannuation or other investments to cash. This risks missing the next upswing while also crystallising any current losses.</p> <p>For example, despite the steep market sell-off in March 2020 as the first COVID lockdowns came into effect, the Australian share market had completely recovered those losses by June 2021.</p> <p>It is good practice for investors to regularly reassess their risk profile to make sure it is right for their current stage of life. This means reducing the allocation to riskier assets as investors get closer to retirement age, while also maintaining a cash buffer to avoid having to sell assets during more turbulent periods such as now.</p> <h2>Super funds are exposed to global risks</h2> <p>The current sell-off has highlighted a potential issue facing the superannuation industry.</p> <p>So much of our superannuation is now invested in global equity markets, mostly in the US, because Australia’s <a href="https://www.abc.net.au/news/2025-04-02/australia-superannuation-retirement-savings/105098840">superannuation savings pool</a> – at more than A$4 trillion – has outgrown the investment opportunities available in Australia.</p> <p>Another issue facing the superannuation industry is the growth of cyber attacks, with several funds <a href="https://theconversation.com/hackers-have-hit-major-super-funds-a-cyber-expert-explains-how-to-stop-it-happening-again-253835">targeted in a recent attack</a>. Given the massive size of the assets held by some funds, it would seem they need to improve their security to be on par with that of the banking system.<!-- Below is The Conversation's page counter tag.

66-year-old woman reveals why she just gave birth to her 10th child

<p>In a remarkable turn of events, 66-year-old Alexandra Hildebrandt gave birth to her 10th child, a healthy baby boy named Philipp, on March 19 at Charité Hospital in Berlin. The birth, carried out via cesarean section, saw Philipp weighing in at 7 pounds, 13 ounces.</p> <p>Hildebrandt, a well-known human rights activist and the director of Berlin’s Checkpoint Charlie Museum, insists that she conceived naturally, without the aid of fertility drugs, and faced no difficulties during the process.</p> <p>Baby Philipp joins an already large and diverse family, including siblings Svitlana (46), Artiom (36), Elisabeth (12), Maximilian (12), Alexandra (10), Leopold (8), Anna (7), Maria (4), and Katharina (2). Remarkably, eight of these children were born after Hildebrandt turned 53, all during her second marriage to former CDU politician Daniel Dormann.</p> <p>For Hildebrandt, having a big family is both fulfilling and fundamental. “A big family is not only something wonderful, but above all, it is important for raising children properly,” she told <em>The Today Show</em>. Despite her age, she has received only positive feedback from friends and family regarding her pregnancy and childbirth.</p> <p>Dr Wolfgang Henrich, Hildebrandt’s OB/GYN, described her pregnancy as “largely uncomplicated”. However, medical experts caution that pregnancies at such an advanced age come with significant risks. Dr Brian Levine, a fertility specialist based in New York City, notes that the biological likelihood of a woman conceiving naturally at 66 is extremely low. Additionally, the risks of hypertension, gestational diabetes, preterm labor and chromosomal abnormalities like Down syndrome rise significantly with age.</p> <p>Hildebrandt is not alone in making headlines for late-life motherhood. In 2023, 70-year-old Safina Namukwaya from Uganda gave birth to twins via in vitro fertilisation using donor eggs and her husband’s sperm. Despite concerns about her age, Namukwaya expressed joy at her newfound motherhood, saying that age should not be a barrier to having children.</p> <p>As for Hildebrandt, she credits her lifestyle for her ability to conceive and carry a child at her age. “I eat very healthily, swim regularly for an hour, walk for two hours,” she shared in an interview with <em>Bild</em>. She also noted that she has never smoked, consumed alcohol or used contraceptives.</p> <p><em>Images: The Today Show</em></p>

Why do I grieve my childhood home so much now we’ve sold it?

<div class="theconversation-article-body"> <p>Grief can hit us in powerful and unanticipated ways. You might expect to grieve a person, a pet or even a former version of yourself – but many people are surprised by the depth of sad yearning they can feel after selling the childhood home.</p> <p>In fact, it is <a href="https://link.springer.com/article/10.1007/s10615-018-0682-5">normal to grieve a place</a>. And this grief can be especially profound if it coincides with a parent dying or moving into residential aged care, leading to the sale of their house.</p> <p>Grief is the response to the loss of anything to which we have an emotional connection. A <a href="https://link.springer.com/article/10.1007/s10615-018-0682-5">growing body</a> of <a href="https://www.taylorfrancis.com/books/mono/10.4324/9780203860731/counting-losses-darcy-harris">research</a> is looking at how grief can extend to “non-person” losses such as infertility, loss of religion and, yes, the loss of a former home.</p> <h2>Why would someone grieve a house?</h2> <p>The childhood home can be an important place for many of us. It literally housed our formative development, family bonds, and core memories. Hopefully, the childhood home is where we learned about safety, security and love.</p> <p>It was likely surrounded by our neighbourhood, and close to important places such as school, playgrounds and friends’ houses. It is no wonder we grieve it when it’s gone.</p> <p>It’s normal to <a href="https://www.taylorfrancis.com/chapters/edit/10.4324/9781315126197-20/grieving-lost-home-marc-fried">grieve things we can’t see and touch</a> but are real and valued. Just as a <a href="https://doi.org/10.1002/pon.70031">serious diagnosis might trigger</a> grief for an imagined future for yourself, or an <a href="https://doi.org/10.1177/1049732314538550">identity</a> you once cherished, loss of a childhood home can hit us harder than we think.</p> <p>When you sell a once-beloved home, you don’t just lose the physical space. You also lose all of what that space might represent, such as birthday celebrations, Christmas lunches, sleepovers with friends or many happy hours playing in the garden.</p> <p>The childhood home often is a symbol of family connection and an anchor in the storm of life. Thinking of the home and all it represents can elicit nostalgia. In fact, the word “nostalgia” <a href="https://www.bps.org.uk/psychologist/nostalgia-cowbells-meaning-life">derives from the Greek</a> words <em>nostos</em> (return) and <em>algos</em> (pain). The word is rooted in the pain we often feel being away from home.</p> <p>And just as siblings are unique – each with different memories of and connections to their childhood home – their responses to its sale can differ markedly. It is normal if your sister or brother grieves the home in a different way to you – or maybe doesn’t even seem to grieve its loss at all.</p> <h2>A complicated grief</h2> <p>When a childhood home is sold because of the death of parents, the feelings of loss about the home are closely linked. The home being sold can be a type of secondary loss that sits in the periphery to the primary loss of parents.</p> <p>Grieving the deaths might, at first, take precedence over the loss of the home.</p> <p>It might only be later that the loss of the home and all it represents becomes apparent. Because the home provides a connection to the deceased person, the loss of the home might add another layer of grief about your parents. Perhaps you find that whenever you recall memories of mum or dad, they seem always to be at the house.</p> <p>It’s also normal if you feel immense <a href="https://link.springer.com/article/10.1007/s10615-018-0682-5">guilt</a> about grieving the home. People might chastise themselves for worrying about “silly things” and not grieving “enough” about the person who died. <a href="https://www.agingcare.com/questions/how-do-i-deal-with-the-guilt-of-selling-moms-house-481550.htm">Guilt about selling the home</a> can also be common.</p> <p>Not everyone has positive memories of their childhood home. Difficult family dynamics, maltreatment and abuse can complicate the emotional connection to childhood spaces and the grief response to their loss.</p> <p>In such cases, the loss of the childhood home can elicit grief about the loss of the childhood that could have – and should have – been. The loss of a home that was the site of discord can be even more challenging than for people with more idyllic childhood experiences.</p> <h2>How can I cope with this loss?</h2> <p>Grief from the loss of a childhood home is <a href="https://link.springer.com/article/10.1007/s10615-018-0682-5">real and valid</a>. We should recognise this and be kind to ourselves and others experiencing it. We shouldn’t minimise the loss or make fun of it.</p> <p>Usually, the loss is anticipated, and this allows you to take photos, furniture or mementos from the home or garden before you leave or sell.</p> <p>Grief researchers call these “<a href="https://www.sciencedirect.com/science/article/pii/S0010440X20300031">transitional</a> <a href="https://www.tandfonline.com/doi/abs/10.1080/13576270412331329812">objects</a>”. They may help you maintain a connection to what is lost, while still grieving the place.</p> <p><a href="https://link.springer.com/article/10.1007/s10615-018-0682-5">Social support</a> while grieving is important. Some people share memories and photos of the home with their siblings, or derive comfort from driving by the home.</p> <p>Just be prepared for the possibility it will likely change as the new owners adapt it to their needs. You might feel affronted, but hopefully can eventually accept the property now belongs to someone else.</p> <p>Chat to your doctor if the loss is particularly difficult, and your grief doesn’t change and subside over time. They might be able to recommend a psychologist who specialises in grief.</p> <p><em>If this article has raised issues for you, or if you’re concerned about someone you know, call Lifeline on 13 11 14.</em><!-- Below is The Conversation's page counter tag.

Yes, it’s a terrible idea to pick up or interfere with wild animals – especially baby wombats. Here’s why

<div class="theconversation-article-body">It was hard to watch. In a now-deleted Instagram reel, American influencer Sam Jones is filmed <a href="https://www.abc.net.au/news/2025-03-12/us-influencer-removes-joey-wombat-from-mother/105041800">picking up</a> a young wombat, separating it from its mother, and running with it back to the car for a pose. In the background, the distressed mother tries to follow. At one point, Jones says: “Momma’s right there and she’s pissed. Let’s let him go.”</p> <p>We have spent our careers working with wildlife. Seeing a joey separated from her mother for social media content was unsettling. The encounter will have made stress levels soar for the baby and mother.</p> <p>Unfortunately, we are seeing a rise in people directly interacting with wildlife through <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/csp2.12958">feeding them</a> or <a href="https://www.tandfonline.com/doi/pdf/10.1080/13683500.2020.1828312">taking risks</a> to get close to them, often driven by the pursuit of social media attention. These interactions can hurt wildlife in <a href="https://theconversation.com/liked-to-death-the-social-media-race-for-nature-photos-can-trash-ecosystems-or-trigger-rapid-extinction-235951">many different ways</a>.</p> <p>While there’s a natural tendency to want to connect with wildlife, wild animals often see humans as a threat. When we get too close, we can trigger fear responses such as increased heart rates and heightened stress hormones. Indeed, the consequences of interfering with wildlife can be <a href="https://doi.org/10.1016/j.scitotenv.2024.175106">far-reaching</a>.</p> <p>Jones was lucky not to have been injured – wombats weigh up to 40 kilograms and have teeth and claws they can use for defence. She could still come down with scabies – wombats often have mange, caused by the parasitic mite which gives us scabies.</p> <p>Others have been less lucky. People feeding dingoes on K'Gari <a href="https://www.theguardian.com/australia-news/2025/feb/02/more-and-more-tourists-are-being-attacked-by-dingoes-on-queenslands-kgari-can-it-be-stopped">has brought</a> these wild canines closer to people, leading to attacks. In response, authorities have occasionally opted to <a href="https://www.theguardian.com/australia-news/2024/jan/21/dingoes-pay-the-ultimate-price-on-kgari-but-some-believe-people-are-the-real-menace">kill</a> dingoes.</p> <p>Official approvals are required to capture and handle wildlife. Engaging in these activities without the necessary permits is typically illegal. These regulations are to safeguard wildlife from harm and protect humans as well.</p> <figure><iframe src="https://www.youtube.com/embed/3PhLPCXPseo?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Instagram clip shows US influencer Sam Jones picking up a baby wombat.</span></figcaption></figure> <h2>What was wrong with the influencer’s behaviour?</h2> <p>What many people found difficult to see in the clip was the clear distress seen in both joey and mother.</p> <p>Wombat joeys are fully dependent on their mothers for between 18 months and two years – one of the longest periods for any marsupial. Interfering with this bond stresses both animals.</p> <p>The incident also took place on a road, increasing their risk of being hit by a vehicle – one of the biggest <a href="https://theconversation.com/2-biggest-threats-to-wombats-revealed-in-new-data-gathered-by-citizen-scientists-215713">threats to wombats</a>.</p> <p>Wildlife are exactly that – wild life. When we interact with wild creatures, we interrupt what they are doing. This can <a href="https://doi.org/10.1016/j.scitotenv.2024.175106">harm</a> the individual – and often, the group – by inducing physical or psychological stress, and changes in behaviour.</p> <h2>We want to connect – but it’s bad for the animals</h2> <p>Many of us draw a mental line between our pets and wild animals. Our cats and dogs jump up for a pat and seek our affection. Wouldn’t wild creatures enjoy the same thing?</p> <p>It took thousands of years to domesticate dogs, cats and other animals. Wild animals, on the other hand, perceive us very differently – often as a potential threat.</p> <p>When we feed wildlife food they are not used to, <a href="https://theconversation.com/how-you-can-help-not-harm-wild-animals-recovering-from-bushfires-131385#:%7E:text=In%20urgent%20cases%2C%20such%20as,wildlife%20veterinary%20hospitals%20for%20care.">it can make</a> them sick, or contribute to long term metabolic issues.</p> <p>Visitors often feed chips to quokkas on Rottnest Island, but these salty snacks can sicken the animals, which should be eating <a href="https://www.publish.csiro.au/wr/wr03051">grasses, stems and leaves</a>.</p> <p>Tourists flock to areas with wild kangaroos and often offer them food. But as they become used to our presence, they can still lash out. People <a href="https://www.theguardian.com/australia-news/2018/may/02/kangaroo-attacks-on-tourists-prompt-warnings-to-stop-feeding-them-junk-food">have been injured</a>, some badly.</p> <figure class="align-center zoomable">Touching animals comes with risks, from being scratched by koalas to being bitten by snakes. When a US wildlife expert was filmed touching a huge great white shark off Hawaii, dozens of people tried to <a href="https://www.abc.net.au/news/2019-01-18/conservationist-slammed-for-touching-huge-shark-off-hawaii/10725478">follow suit</a> – despite the risks.</figure> <p>Then there’s the disease risk. Wombats suffer from <a href="https://theconversation.com/2-biggest-threats-to-wombats-revealed-in-new-data-gathered-by-citizen-scientists-215713">sarcoptic mange</a>, while other marsupials may have <a href="https://theconversation.com/toxoplasma-the-parasite-that-takes-over-our-brains-197100">toxoplasmosis</a>, which can trigger miscarriages and neurological issues. Handling wild birds can give us the dangerous disease <a href="https://en.wikipedia.org/wiki/Psittacosis">psittacosis</a>.</p> <p>If you don’t have a permit, you should stay at a safe distance and watch the animal. The goal is to avoid interfering, and respect the animal’s autonomy and what it’s trying to do, whether that’s finding food, finding a mate, sleeping, or just lounging about.</p> <h2>Are more people trying to interact with animals?</h2> <p>After the COVID pandemic, many of us have been seeking outdoor experiences. Camping is <a href="https://www.austrade.gov.au/en/news-and-analysis/news/the-rise-of-nature-based-tourism-in-australia">on the rise</a>, as is ecotourism.</p> <p>At the same time, some influencers are trying to interact with wildlife, perhaps mimicking famous figures such as the late Steve Irwin. Irwin’s father, Bob, recently <a href="https://www.theguardian.com/australia-news/2023/apr/06/queensland-urged-to-prosecute-would-be-influencers-who-enter-crocodile-habitat">called for</a> harsher penalties for influencers entering crocodile territory after many close calls.</p> <p>Watching trained wildlife handlers can give us false confidence. We might think: if they do it, why can’t I?</p> <p>The problem is, wildlife handling is risky. Bites are common, even for trained experts. When we undertake wildlife research, we use gloves, cages, hoods and so on to reduce the risk to us and the stress to the animal.</p> <p>Wildlife carers who take on the role of rearing wombat joeys have to be <a href="https://doi.org/10.1071/AM24025">well trained</a> – and dedicated. Joeys need to be fed special milk <a href="https://theconversation.com/wallaby-joeys-and-platypus-puggles-are-tiny-and-undeveloped-when-born-but-their-mothers-milk-is-near-magical-207726">suited to marsupials</a> – cow’s milk is no good. They have to be fed round the clock in the early months.</p> <p>In many cases we are aware of, untrained individuals have attempted to rescue wombats or kangaroo joeys only to discover they can’t meet their specific care needs. Unfortunately, this often results in the joeys being abandoned or handed over to wildlife carers in poor condition.</p> <p>This doesn’t mean that interactions with animals are off-limits. Zoos and wildlife sanctuaries provide opportunities to handle captive animals under expert supervision. Volunteering with wildlife carers or training to become a carer are viable ways to engage with animals responsibly.</p> <p>Influencers don’t have to grab an animal from the wild to show how amazing it is. You can show natural behaviour by following an animal from a safe distance or use existing footage.</p> <p>If you can’t captivate an audience with the wonders of wildlife without harassing a wild animal, then perhaps it’s time to rethink and refine your social media strategy.</p> <p>When we are out in the bush, it’s natural to be fascinated by the presence of wild creatures. But we must find ways of building our connection with nature without harming what we see – and without risking harm to ourselves.<!-- Below is The Conversation's page counter tag.

A late start, then a big boom: why it took until 1975 for Australians to finally watch TV in colour

<div class="theconversation-article-body"> <p>Some 50 years ago, on March 1 1975, Australian television stations officially moved to colour.</p> <p>Networks celebrated the day, known as “<a href="https://artsandculture.google.com/story/c-day-and-the-colour-monster-national-archives-of-australia/LAWRcgnnNY1cKA?hl=en">C-Day</a>”, with unique slogans such as “come to colour” (ABC TV), “Seven colours your world” (Seven Network), “living colour” (Nine Network) and “first in colour” (<a href="https://televisionau.com/feature-articles/network-ten">0-10 Network</a>, which later became Network Ten). The ABC, Seven and Nine networks also updated their logos to incorporate colour.</p> <figure><iframe src="https://www.youtube.com/embed/T7gZdYVZJNc?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>For most viewers, however, nothing looked much different. The majority owned a black and white TV, while a coloured broadcast required a colour TV set.</p> <p>Advertisers were initially reluctant to accept the change, which required them to re-shoot black and white commercials with colour stock at a significantly higher cost.</p> <p>Many reasoned viewers were still watching the ads in black and white. And initially this assumption was correct. But by nine months later, 17% of Australian homes <a href="https://trove.nla.gov.au/newspaper/article/110829595?searchTerm=colour%20television%20in%20australia%201975">had a colour receiver</a>. This rose to 31% by July 1976.</p> <p>By 1978, 64% of Melbourne and 70% of Sydney households owned colour TV sets, making Australia one of the world’s fastest adopters of colour TV.</p> <p>According to the Federation of Australian Commercial Television Stations (FACTS) annual report for 1975–76, colour TV increased overall viewership by 5%, with people watching for longer periods.</p> <p>The 1976 Montreal Olympics also led to an <a href="https://www.nfsa.gov.au/collection/curated/asset/96836-olympic-games-coverage-colour">increase in TV sales</a>, with the colour broadcast shared between the ABC, Seven and Nine.</p> <figure><iframe src="https://www.youtube.com/embed/L-75iIoshak?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Highlights from the Montreal 1976 Olympic Games marathon event.</span></figcaption></figure> <h2>A late start</h2> <p>With the United States introducing colour TV from 1954, it’s peculiar that Australia took so long to make the transition – especially since conversations about this had been underway since the 1960s.</p> <p>In 1965, a report outlining the process and economic considerations of transitioning to colour was tabled in parliament.</p> <p>Feedback from the US highlighted problems around broader acceptance in the marketplace. Colour TV sets were expensive and most programs were still being shot in black and white, despite the availability of colour.</p> <p>Networks were the most hesitant (even though they’d go on to become one of the most major benefactors). In 1969, it was <a href="https://australianfoodtimeline.com.au/colour-tv-introduced/">estimated transitioning to colour</a> would cost the ABC A$46 million (the equivalent of $265,709,944 today) over six years.</p> <p>The federal government, led by then prime minister Robert Menzies, decided to take a cautious approach to the transition – allowing manufacturers, broadcasters and the public time to prepare.</p> <p>The first colour “test” broadcast took place on June 15 1967, with <a href="https://televisionau.com/2025/03/tv-50-years-in-colour.html">live coverage</a> of a Pakenham country horse racing event in Victoria (although few people would have had coloured TV sets at this point).</p> <p>Other TV shows also tested broadcasting in colour between 1972 and 1974, with limited colour telecasts aired from mid-1974. It wasn’t until March 1975 that colour TV was being transmitted permanently.</p> <figure><iframe src="https://www.youtube.com/embed/vIqqiK4ncfs?wmode=transparent&amp;start=40" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">‘Aunty Jack Introduces Colour’ was a one-off television special of The Aunty Jack Show, broadcast on the ABC on February 28 1975.</span></figcaption></figure> <h2>The cinema industry panics</h2> <p><a href="https://anzacportal.dva.gov.au/wars-and-missions/vietnam-war-1962-1975/events/withdrawal-from-1971">Australia’s involvement</a> in the Vietnam War created further urgency to televise in colour. With the war ending in April 1975, Australians watched the last moments in colour.</p> <p>Other significant events broadcast in colour that year included the December federal election, in which Malcolm Fraser defeated Gough Whitlam after the latter was <a href="https://www.youtube.com/watch?v=SXq056TJhU4">dramatically dismissed</a> as prime minister on November 11.</p> <p>With the public’s growing interest in colour TV, local manufacturers began lobbying for higher tariffs on imports to encourage domestic colour TV production.</p> <p>In the mid 1970s, a new colour set in Australia cost between $1,000 and $1,300, while the average full-time annual income was <a href="https://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/6302.0Main+Features1Sep%201975?OpenDocument=">around $8,000</a>. Still in the throes of a financial recession, customers began seeking out illegally-imported colour TV sets – which were appearing at car boot markets across the country.</p> <figure><iframe src="https://www.youtube.com/embed/wTKMqPg4hM8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">British childrens show The Wombles came to Australian screens shortly after colour TV was introduced.</span></figcaption></figure> <p>The government also created an advertising campaign warning the public of scammers who would offer to convert black-and-white TVs to colour. These door-to-door “salesmen” <a href="https://hoaxes.org/archive/permalink/instant_color_tv#google_vignette">claimed to have</a> a special screen which, when placed over a TV, would magically turn it colourful.</p> <p>By 1972, the estimated cost of upgrading broadcasting technology to colour <a href="https://www.nfsa.gov.au/latest/colour-tv-part-1">had reached $116 million</a>. The cinema industry, in a panic, even questioned whether colour TV could damage a viewer’s eyesight.</p> <p>The industry had previously suffered huge losses in cinema attendance with the introduction of black-and-white TV from 1956. Cinemas had a monopoly on colour and were petrified over what the introduction of colour to television could do to their attendances.</p> <p>Such fears were founded. In 1974 Australia had 68 million admissions to the cinema. By 1976, there were just 28.9 million admissions. Never again would yearly cinema admissions reach <a href="https://www.screenaustralia.gov.au/fact-finders/cinema/industry-trends/historical-admissions">above 40 million</a>.</p> <p>But despite the complaints – from the cinema industry, advertisers, broadcasters and manufacturers – audiences were ready for colour. And any network that dared to program in black and white would subject itself to a barrage of annoyed viewers.</p> <p>Colour TV was here to stay.<!-- Below is The Conversation's page counter tag.

Why Alfred is such an "unusual" cyclone

<div class="theconversation-article-body"> <p>Cyclone Alfred has now been delayed, as the slow-moving system <a href="https://www.theguardian.com/australia-news/2025/mar/06/cyclone-alfred-news-update-landfall-when-will-it-hit-why-did-it-slow-down">stalls</a> in warm seas off southeast Queensland. Unfortunately, the expected slow pace of the cyclone will bring even more rain to affected communities.</p> <p>This is because it will linger for longer over the same location, dumping more rain before it moves on. Alfred’s slowing means the <a href="https://www.abc.net.au/news/2025-03-06/cyclone-alfred-stalling-at-sea-later-landfall/105016522">huge waves</a> triggered by the cyclone will last longer too, likely making coastal erosion and flooding worse.</p> <p>Cyclone Alfred is unusual – the first cyclone in half a century to come this far south and make expected landfall.</p> <p>When unusual disasters strike, people naturally want to know what role climate change played – a process known as “climate attribution”. Unfortunately, this process takes time if you want details on a specific event.</p> <p>We can’t yet say if Alfred’s unusual path and slow speed are linked to climate change. But climate change <em>is</em> driving very clear trends which can load the dice for more intense cyclones arriving in subtropical regions. These include the warm waters which fuel cyclones spreading further south, and cyclones dumping more rain than they used to.</p> <p>So, let’s unpick what’s driving Cyclone Alfred’s behaviour – including the potential role of climate change.</p> <figure><iframe src="https://www.youtube.com/embed/ADuTsiDlMh8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">A Bureau of Meteorology update on Cyclone Alfred dated Thursday, March 6.</span></figcaption></figure> <h2>Not necessarily climate linked: Alfred’s southerly path</h2> <p>Many cyclones make it as far south as Brisbane – but they’re nearly all far out at sea. Weather patterns mean most cyclones heading south are diverted to the east, where remnants can hit New Zealand as large extratropical storms.</p> <p>The fact that Alfred is set to make landfall is very unusual. But we can’t yet definitively say this is due to climate change. Cyclones are steered by winds and weather patterns, and the Coral Sea’s complex weather makes cyclone paths here very hard to predict.</p> <p>Alfred’s abrupt westward shift is due to a large region of high pressure to its south, which has pushed it directly towards heavily populated areas of southeast Queensland and northern New South Wales. These steering winds are not very strong, which is why Alfred is moving slowly.</p> <p>In 2014, <a href="https://www.nature.com/articles/nature13278">researchers showed</a> cyclones are reaching their maximum intensity in areas further south in the southern hemisphere and north in the northern hemisphere than they used to. In 2021, researchers also found cyclones were reaching their <a href="https://www.science.org/doi/10.1126/science.abb9038">maximum intensity</a> closer to coasts, moving about 30 km closer per decade.</p> <h2>Climate link: Warmer seas</h2> <p>Cyclones typically need water temperatures of 26.5°C or more <a href="https://www.csiro.au/en/news/All/Articles/2025/March/things-to-know-about-tropical-cyclones">to form</a>.</p> <p>More than 90% of all extra heat trapped by greenhouse gas emissions is stored <a href="https://www.climate.gov/news-features/understanding-climate/climate-change-ocean-heat-content">in the seas</a>.

This means more rain per cyclone, on average.</p> <p>Rising ocean temperatures mean more water evaporates off the sea surface, meaning forming cyclones can absorb more moisture and dump more rain when it reaches land.</p> <p>Why are cyclones slowing down? This is likely because air current circulation in the tropics has weakened. This has a clear link to climate change. Wind speeds have fallen <a href="https://www.nature.com/articles/s41558-018-0227-5">5 to 15%</a> in the tropics, depending on where you are in the world. It’s hard to pinpoint the change clearly in our region, because the historic record of cyclone tracks isn’t very long.</p> <p>For every degree (°C) of warming, rainfall intensity increases 7%. This is <a href="https://wmo.int/topics/extreme-weather">well established</a>. But <a href="https://theconversation.com/supercharged-thunderstorms-have-we-underestimated-how-climate-change-drives-extreme-rain-and-floods-228896">newer research</a> is showing the rate may actually be <a href="https://hess.copernicus.org/articles/28/1251/2024/hess-28-1251-2024-assets.html">double this</a> or <a href="https://doi.org/10.1029/2024EF004808">even higher</a>, as the process of condensation releases heat which can trigger more rain.</p> <h2>Clear climate link: Bigger storm surges due to sea level rise</h2> <p>Sea levels are on average about <a href="https://www.climate.gov/news-features/understanding-climate/climate-change-global-sea-level">20 centimetres higher</a> than they were before 1880.</p> <p>When a cyclone is about to make landfall, its intense winds push up a body of seawater ahead of it – the storm surge. In low lying areas, this can spill out and flood streets.</p> <p>Because climate change is causing baseline sea levels to rise, storm surges can reach further inland. Sea-level rise will also make coastal erosion more destructive.</p> <h2>What should we take from this?</h2> <p>We can’t say definitively that climate change is behind Cyclone Alfred’s unusual track.</p> <p>But factors such as rising sea levels, slower cyclones and warmer oceans are changing how cyclones behave and the damage they can do.</p> <p>Over time, we can expect to see cyclones arriving in regions not historically affected – and carrying more rain when they arrive.<!-- Below is The Conversation's page counter tag.

‘Don’t panic, do prepare’: why it’s not too late to plan for Cyclone Alfred

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/yetta-gurtner-2337172">Yetta Gurtner</a>, <a href="https://theconversation.com/institutions/james-cook-university-1167">James Cook University</a></em></p> <p>For millions of people in southeast Queensland and northern New South Wales, Cyclone Alfred will be their first experience living through a cyclone. Alfred is forecast to make landfall about 2am on Friday morning.</p> <p>I am a disaster expert based in northern Queensland, which regularly experiences cyclones. In my other role as an acting SES public information officer, I’m heading south to the Gold Coast to help residents prepare and respond.</p> <p>Here’s what I want you to know. First, don’t panic. Second, do prepare.</p> <p>Preparation has several steps. It’s important to clearly assess your specific threat. If you live near the sea, storm surges – where the sea spills inland – could be a significant threat, while flooding might pose a large risk if you live near a river – especially in the few days after Alfred passes. The highest rainfall is likely on Alfred’s southern flank from the Gold Coast down to northern New South Wales.</p> <p>Having enough food, water and medication is vital. Be ready to evacuate too, in case authorities deem it necessary. Check your local council’s disaster website, disaster apps and stay tuned to the ABC, which will run disaster alerts.</p> <figure><iframe src="https://www.youtube.com/embed/EN_yKcjlF20?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">The Bureau of Meteorology’s latest update on Cyclone Alfred’s path and likely impact, as of the morning of Wed 5th March.</span></figcaption></figure> <h2>What should I do right now?</h2> <p>If you’re in the <a href="http://www.bom.gov.au/products/IDQ65002.shtml">danger zone</a>, make preparations now, before the full intensity of the cyclone arrives.</p> <p>Tie down loose objects. Clean gutters to avoid overflow from torrential rain. And prepare your “go bag” – a bag of essentials you can throw in the car if authorities tell you to leave immediately. Don’t take too much – just the bare necessities.</p> <p>Buy an AM/FM radio and tune it to ABC National, as you cannot be sure mobile networks will function. Radio is a reliable way to get good information from the ABC, Australia’s designated <a href="https://www.abc.net.au/emergency">emergency channel</a>.</p> <p>Make sure the car is fuelled or charged. If you’ve got a generator, make sure you have fuel and the generator is positioned outside in a well-ventilated area.</p> <p>Water is often unreliable after disasters. Fill your bathtub or front-loader washing machine with water. Put containers of water in your freezer, to keep food cold if the power goes out and as another water source. Plan for days of power outages. Protect windows with plywood, heavy blankets or mattresses. Put a mattress between your car and garage roller door to stop it blowing in.</p> <p>Turn off gas, electricity and solar power.</p> <p>Authorities recommend using sandbags to reduce the chance of water getting in. You can get sacks from hardware stores or council-run emergency centres, if available, who also provide sand. You also need plastic sheeting.</p> <p>If there’s a shortage of sand, you can use garden soil or commercial bagged soil. If you can’t get sacks, large plastic shopping bags will do.</p> <p>Tape strong plastic sheeting around the door or low window where water might get in. This is the barrier that actually keeps water out – sandbags keep it in place.</p> <p>Fill sandbags and lay them <a href="https://www.ses.nsw.gov.au/during-emergency/sandbags">like bricks</a>. Lay one row, and lay the next row offset for strength.</p> <p>Sandbags are good, but they have limits. There’s little point in piling sandbags higher than about 30 centimetres. If floodwaters edge higher, water will get through.</p> <p>Many people have had the unpleasant experience of having effluent come back up through toilets during cyclones and subsequent flooding. To stop this, cover your toilet with plastic sheeting (directly on the porcelain) and put a sandbag on top for weight. Do the same for any drains where water might flow back up.</p> <p>To reduce water damage, put valuable or important items up high, atop tables or bunk beds or upstairs if you have a second storey.</p> <h2>What will it be like when Alfred hits?</h2> <p>When the cyclone first hits, it can be overwhelming. The sound is like a roaring jet engine.</p> <p>If you haven’t been advised to evacuate by authorities, you will be sheltering in place.</p> <p>This means finding the safest room in the house, to avoid damage from flying objects. Choose the smallest room with the fewest windows – a bathroom or a room under the stairs. Basements are very safe, but will be the first affected by water.</p> <p>As the cyclone picks up intensity, set up inside this safe room with your pets and children. Do not leave this room until you have been told it’s safe by authorities.</p> <p>At the centre of strong cyclones is the eye of the storm, which we experience as a period of sudden calm. People often make the mistake of thinking it’s over. But in fact, it’s just a brief reprieve before the intense winds pick up again. Don’t make the mistake of leaving the house – check with authoritative sources.</p> <p>Cyclone Alfred is a <a href="https://www.abc.net.au/news/2025-03-05/cyclone-alfred-unusual-triplet-storm-climate-change-factors/105008704">slow-moving cyclone</a>, which means you might be stuck inside for a while. Be prepared to be inside your house for up to 24 hours, even after the worst has passed. This is because there may well be downed powerlines with live electricity, broken glass, falling trees and so on.</p> <p>For your children (and yourself), being in the cyclone is frightening. Young kids find the sound chilling. You can play music through headphones to help soothe them. Board games, books and puzzles can help pass the time. You will need distraction. Have a bucket in the corner for emergency toilet needs.</p> <p>Keep track of the storm and any emerging dangers through your radio and internet-enabled phone (if still functioning).</p> <h2>What if I have to evacuate?</h2> <p>Authorities are working to set up evacuation centres for people whose homes may not be safe. Authorities will go door-to-door to tell affected residents to leave, as well as broadcasting the information on radio and online.</p> <p>You’re more likely to have to evacuate if your house is on low-lying land near the sea, as a storm surge is likely. How much water is pushed ashore will depend on the tide, but it could be as high as 70cm above the high tide line if we’re unlucky.</p> <p>Evacuations can happen after the cyclone too. Alfred is packing a lot of rain – <a href="https://www.weatherzone.com.au/news/tropical-cyclone-alfred-could-disrupt-afl-and-nrl-matches/1890420">up to a metre</a> in some areas. That’s very likely to cause flooding, both flash floods and rivers breaking their banks.</p> <p>If you are asked to evacuate, you can go to the house of a friend or family member if it’s on higher ground and outside the flood risk zones. Or you can go to a local evacuation centre – check your council website to see where your closest one is. Take as little as possible with you.</p> <p>Many people who choose not to evacuate do so because they’re worried about their pets. This is risky. Some evacuation centres do take pets, so check now. If they don’t, look for other options with friends and family. Staying put after an evacuation order is dangerous.</p> <h2>What will happen after the cyclone?</h2> <p>Cyclone Alfred brings three threats: intense winds, high seas and heavy rain.</p> <p>After the intense winds die down, the seas will be dangerous for days after Alfred. There are coastal hazard warnings for about 1,000km of coastline.</p> <p>Cyclones also often decay into tropical low weather systems, which dump heavy rain for days. This is likely.</p> <p>As you move into recovery phase, don’t relax your guard. In far north Queensland, 16 people have <a href="https://www.abc.net.au/news/2025-03-04/melioidosis-death-toll-rises-in-queensland/105009772">now died</a> after being infected with melioidosis, a bacterium found in mud. The bug is <a href="https://theconversation.com/theres-an-outbreak-of-melioidosis-in-north-queensland-heres-what-to-know-about-this-deadly-mud-bug-250392">more prevalent</a> after heavy rainfall.</p> <p>Wear protective gear such as gloves and face masks when dealing with water-damaged goods and mud, and pay close attention to the latest advice authorities are giving.</p> <p>But remember – don’t panic. We will get through this.<!-- Below is The Conversation's page counter tag.

Why you should revisit the classics, even if you were turned off them at school

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/johanna-harris-305384">Johanna Harris</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p>Throughout my school years I had an exuberant, elderly piano teacher, Miss Hazel. She was one of five daughters (like me) and, like many young women of her generation, had never married her sweetheart because he did not return from the war.</p> <p>Her unabashed gusto for life and infectious, positive outlook left an indelible impression upon me. So too did the memorable fact that Miss Hazel read Jane Austen’s <a href="https://www.goodreads.com/book/show/84979.Pride_and_Prejudice">Pride and Prejudice</a> from beginning to end once every year.</p> <p>As a younger girl I wondered about the ways Pride and Prejudice could be so important to a woman in her eighties that she would want to read it annually. Was it to do with Austen’s depiction of a family with five daughters, or to relive an endearing love story?</p> <p>Since those years I have seen, more through lived experience than through academic study, just how deeply meaningful the reading of classic books, like Pride and Prejudice, can be.</p> <figure class="align-left zoomable"></figure> <p>I no longer simply read this book for Elizabeth Bennett’s love story, but for the finely crafted replication Austen gives us of human character, with all its flaws. Hers are imaginary yet imaginably real situations, all depicted with humour and a sensitively calibrated dose of sympathy for even the most unlikeable literary figures.</p> <p>The clergyman Mr Collins, Elizabeth’s distant cousin and her rejected suitor, was always repellent for his obsequiousness but I see more readily now his self-serving nature cloaked in altruism. The haughty snobbery of Darcy’s aristocratic aunt, Lady Catherine de Bourgh, hints at a deeper layer of sadness and fragility only rereading can illuminate.</p> <h2>Box-ticking and speed</h2> <p>When we’re at school or university we may read for speed. I remember managing my reading of Ann Radcliffe’s 432-page gothic romance <a href="https://www.goodreads.com/book/show/93135.The_Romance_of_the_Forest?from_search=true&amp;from_srp=true&amp;qid=oU6912stkW&amp;rank=1">The Romance of the Forest</a> to work out how many pages per hour I would need to read across a weekend in order to finish the novel before my university tutorial. (It was an ungodly ratio and I don’t recall much of the novel.)</p> <figure class="align-right zoomable"></figure> <p>Or we may read for the tick-box exercise of writing for assessment requirements: accumulating knowledge of a novel’s original metaphors, descriptions that best capture a prescribed theme (“belonging” or “identity”), or of poetry by which we can demonstrate a grasp of innovative metre.</p> <p>But how and why do we reread classic books, when we are not constrained by class plans or prescribed exam themes. And why should we?</p> <h2>‘Like a graft to a tree’</h2> <p>Rebecca Mead’s <a href="https://www.goodreads.com/book/show/20924311-the-road-to-middlemarch?from_search=true&amp;from_srp=true&amp;qid=Cm2E7fwgeL&amp;rank=1">The Road to Middlemarch</a> offers a compelling exploration of one writer’s five-yearly revisitation of George Eliot’s masterpiece, <a href="https://www.goodreads.com/book/show/19089.Middlemarch?from_search=true&amp;from_srp=true&amp;qid=CRcxE3ftkB&amp;rank=1">Middlemarch</a>.</p> <p>Mead first read the novel at school, and Eliot’s subtitle to the novel, “A Study of Provincial Life”, captured precisely what Mead was trying to escape at that time: provinciality.</p> <p>Eliot’s central character, Dorothea Brooke, captivated Mead as an unconventional intellectual heroine yearning for a life of meaning and significance. Mead marked out important moments with a fluorescent pen, such as when the intellectual and spiritual inadequacies of Dorothea’s husband, <a href="https://www.britannica.com/topic/Edward-Casaubon">Casaubon</a>, dawn upon her. Mead writes, quoting Eliot:</p> <blockquote> <p>‘Now when she looked steadily at her husband’s failure, still more at his possible consciousness of failure, she seemed to be looking along the one track where duty became tenderness […]’ These seemed like things worth holding on to. The book was reading me, as I was reading it.</p> </blockquote> <figure class="align-left zoomable"></figure> <p>This idea of books “reading us” can sound like an odd animism. But books can prompt us to reflect on our own lives, too. Eliot makes Middlemarch almost compulsory to reread later in life: the idealism of youth captures the young reader, while the novel’s humour becomes more sympathetic as we age. To reread a novel like Middlemarch is to trace the ways we too have experienced idealism turn to illusion, or have seen the restless pursuit of change turn to a retrospective gratitude and a recognition of grace.</p> <p>Our ability to acknowledge new depths of meaning in our own lives and to recognise within ourselves a subtler sympathy for the lives of others can be articulated almost as precisely as lived experience itself. As Mead says, “There are books that grow with the reader as the reader grows, like a graft to a tree.”</p> <h2>Feeling for Lear</h2> <p>The same can be said of Shakespeare. As young readers, we won’t necessarily capture the full vision <a href="https://www.goodreads.com/book/show/12938.King_Lear?from_search=true&amp;from_srp=true&amp;qid=nowKY1f5aB&amp;rank=1">King Lear</a> offers us of the tragicomic paradoxes sometimes presented by old age. The play depicts the loss of power and control over one’s life and decision-making, the tender fragility of family relationships when the care of aged parents is suddenly an urgent question and the madness that can prevail when an inheritance is at stake.</p> <figure class="align-right zoomable"></figure> <p>Some of these things might abstractly be understood when taught to us in the classroom, but they are far more powerfully seen when revisited after we have lived a little more of that imaginably real life ourselves.</p> <p>As students we might have squirmed with discomfort at the literal blinding of Lear’s loyal subject the Earl of Gloucester (the horror of witnessing a visceral, grotesque injury).</p> <p>But as we age it is the tragedy of moral blindness that lingers, making the final scene so extraordinarily moving: “Do you see this? Look on her. Look, her lips. Look there, look there,” Lear pleads, as if to say that Cordelia, lifeless in his arms, still breathes.</p> <p>Does he really see her lips quiver? Does he really believe she lives? Is this some consolation with which he dies or is it delusion? Lear’s heart is broken. So is mine.</p> <p>Each time I revisit this final scene, the grief of Lear as a father is profoundly felt, but my heart is broken even more so by his continuing blindness; his vision (what he thinks he sees) is desperate, untrue, and ultimately meaningless.</p> <h2>Sites of discovery</h2> <p>When we read we inhabit imaginary worlds and each time the reading can be different. Philip Davis, a professor of literature and psychology <a href="https://global.oup.com/academic/product/reading-and-the-reader-9780199683185?cc=au&amp;lang=en&amp;">has written</a>,</p> <blockquote> <p>Rereading is important in checking and refreshing that sense of meaning, as the reader goes back and re-enters the precise language once again.</p> </blockquote> <p>Davis points to an idea advanced by the novelist and philosopher Iris Murdoch, of the reader’s collection of special, memorable fragments, which serve as metaphors for the reader’s self-utterances, developed over time. These are “nascent sites for thinking and re-centring”.</p> <p>This is a similar idea to the novelist and journalist Italo Calvino’s description in <a href="https://www.goodreads.com/book/show/9814.Why_Read_the_Classics_?from_search=true&amp;from_srp=true&amp;qid=RALd1Dx5a9&amp;rank=1">Why Read the Classics?</a> of the way classic books “imprint themselves on our imagination as unforgettable” and “hide in the layers of memory disguised as the individual’s or the collective unconscious.”</p> <p>Works of imaginative literature are not manuals for life, though they might along the way gift us with some wisdom; they are sites of discovery and rediscovery.</p> <p>The classic works we are introduced to at school may establish such sites for thinking about ourselves and others, but it is in rereading them as we grow older that we can better see the ways we have grown as imaginative, moral beings.<!-- Below is The Conversation's page counter tag.

From sunscreen to essential oils, why some personal care products could be harmful to your health

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/asit-kumar-mishra-1458839">Asit Kumar Mishra</a>, <a href="https://theconversation.com/institutions/university-college-cork-1321">University College Cork</a></em></p> <p>Each time you apply sunscreen to your face, you may inhale somewhere between <a href="https://www.mdpi.com/1660-4601/20/11/5944">10 to 30 milligrams of ethanol</a>, the type of alcohol used in alcoholic drinks. While the ethanol in sunscreen may not give you a buzz, it could make you think about what other chemicals you might be exposed to from personal care products.</p> <p>Products that are applied to the face, like sunscreen, can increase the inhalation of some chemicals by ten times or more than you would inhale from your <a href="https://pubmed.ncbi.nlm.nih.gov/34816489/">home air in the entire day</a>.</p> <p>The levels of ethanol in cosmetics and skincare products may be reasonably safe – although it can still dry out the skin, causing pain, redness and swelling, and <a href="https://www.gov.uk/government/publications/ethanol-properties-uses-and-incident-management/ethanol-general-information">irritate the eyes</a>, causing tears, burning and stinging – but personal care products such as shampoos, skin creams, deodorants, cosmetics and perfumes contain fragrances and other volatile organic compounds (VOCs), which can be inhaled, absorbed through skin or ingested and some are more toxic than others.</p> <p>Unfortunately, manufacturers of personal care products <a href="https://link.springer.com/article/10.1007/s11869-015-0327-6">do not have to disclose</a> every fragrance compound used. This is concerning when you consider the potential effects of toxic compounds that <a href="https://pubmed.ncbi.nlm.nih.gov/34816489/">have been detected</a> in the air from personal care products. For example, hair-smoothing products have released formaldehyde, a toxic chemical that can cause <a href="https://www.ncbi.nlm.nih.gov/books/NBK597627/">a range of symptoms</a> from dermatitis to low sperm count. Some perfumes and deodorants have generated monoterpenes, chemicals which <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8912113/#sec1-molecules-27-01716">can prove toxic</a> for some users.</p> <figure><iframe src="https://www.youtube.com/embed/cfloNXKeyX8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Some of the VOCs found in personal care products <a href="https://pubmed.ncbi.nlm.nih.gov/36976159/">may trigger</a> skin irritation, headaches – and difficulty breathing, which can develop into an asthma attack in some users. The highest or peak concentration of these VOCs are likely to <a href="https://pubmed.ncbi.nlm.nih.gov/22406137/">occur within ten minutes</a> of application. But these concentrations may take up to <a href="https://pubmed.ncbi.nlm.nih.gov/34816489/">two hours to decrease to background levels</a>, depending on your home’s ventilation.</p> <h2>Natural doesn’t mean risk free</h2> <p>But even if the levels of <a href="https://pubmed.ncbi.nlm.nih.gov/20659630/">VOCs in personal care products</a> are kept <a href="https://pubmed.ncbi.nlm.nih.gov/22406137/">within safe limits</a>, they can still cause discomfort and a variety of health issues, including irritation of the eyes and airways, migraines and asthmatic reactions, in those who’re <a href="https://enveurope.springeropen.com/articles/10.1186/s12302-020-00311-y">fragrance sensitive</a>. In the UK, <a href="https://link.springer.com/article/10.1007/s11869-018-00655-8">27% of the population</a> self reports as fragrance sensitive.</p> <p>It makes sense then that some people attempt to avoid potentially toxic synthetic chemicals in cosmetics by opting for “natural” or “clean” personal care products. But, <a href="https://enveurope.springeropen.com/articles/10.1186/s12302-020-00311-y">natural does not mean safer</a>.</p> <p>For instance, essential oils are often used in “natural” personal care products as fragrance. Essential oils, though, are a source of terpenes, some of which can be <a href="https://www.lung.org/blog/essential-oils-harmful-or-helpful">toxic if absorbed, inhaled or swallowed</a>.</p> <p>Indoor concentration of terpenes are often at levels where you can smell them but not high enough to cause <a href="https://pubmed.ncbi.nlm.nih.gov/28126407/">eye or respiratory tract irritation</a>. However, the terpenes from essential oils can react with other chemicals, such as ozone from outdoor air, producing <a href="https://pubmed.ncbi.nlm.nih.gov/32162221/">byproducts like formaldehyde, a known carcinogen</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/22250748/">allergens</a>.</p> <h2>Beauty salon safety</h2> <p>Beauty salons can be particularly risky environments for exposure to VOCs. <a href="https://www.mdpi.com/1660-4601/19/7/4176">Studies have found</a> contaminants such as formaldehyde, ammonia and <a href="https://www.gov.uk/government/publications/toluene-properties-incident-management-and-toxicology/toluene-toxicological-overview">toluene</a>, a potentially harmful ingredient used in many personal care products, at high levels in salons, putting staff who work there at the highest risk.</p> <p>Formaldehyde levels in some salons have reached <a href="https://pubmed.ncbi.nlm.nih.gov/31321727/">above safety limits</a>. <a href="https://www.dcceew.gov.au/environment/protection/npi/substances/fact-sheets/methyl-methacrylate#tabs-2">Methyl methacrylate</a>, which can cause skin irritation, allergic reactions and potential <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3072694/">respiratory issues</a> has been <a href="https://pubmed.ncbi.nlm.nih.gov/30276513/">detected in the air of nail salons</a>.</p> <figure><iframe src="https://www.youtube.com/embed/ydRklqO01fE?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>These contaminants are not necessarily limited to the places in a salon <a href="https://pubmed.ncbi.nlm.nih.gov/23765035/">where a certain product is being used</a>. Beauty salons with poor ventilation are likely to expose workers and customers to <a href="https://pubmed.ncbi.nlm.nih.gov/29494285/">much higher levels of contaminants</a>. Some of the components of personal care products are known, harmful contaminants and carcinogens.</p> <p>Regulations specifically related to ventilation in environments where large volumes of these products are used do reduce exposures. For instance, studies show that after ventilation regulations came into effect in Boston, US in 2011, the <a href="https://pubmed.ncbi.nlm.nih.gov/31622145/">air quality inside nail salons improved</a>.</p> <p>When visiting your nail salon or hair stylist, check with them about their ventilation system and other steps they are taking to reduce exposure to VOCs.</p> <p>To limit exposure to potential VOCs at home when using personal care products, try to open windows and use extractor fans in wet rooms. Be especially careful when applying products to the face or when using a high temperature application – <a href="https://occup-med.biomedcentral.com/articles/10.1186/s12995-018-0213-x">high temperatures can increase emissions</a>.<!-- Below is The Conversation's page counter tag.

Why physical affection can boost your health

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/viren-swami-241976">Viren Swami</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p>In the opening scene of <a href="https://www.youtube.com/watch?v=H9Z3_ifFheQ">Love, Actually</a>, Hugh Grant’s character says how, whenever he gets gloomy with the state of the world, he thinks about the arrivals gate at Heathrow airport. The reason is on screen: we see couples kissing, old friends embracing, children smiling and laughing as they jump into the arms of their parents.</p> <p>Airports are great places to really understand the importance of physical affection – hugging, kissing, cuddling, holding hands, or even just touching. But physical affection is ubiquitous in everyday life, too – and with good reason. Science shows that non-sexual physical affection produces more than just moments of joy – it also <a href="https://www.tandfonline.com/doi/abs/10.1080/03637751.2020.1805480?casa_token=DrsRLnkOANAAAAAA:u8gR6dQFL2Jp99tIr3m1Bcm14hc-EwVrbckdpuDX0HyWEBDrzoUcxNYpkCQzXP5oD_IhHqzYo7Fj">benefits</a> our mental and physical health.</p> <figure><iframe src="https://www.youtube.com/embed/PlyMXYys16U?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Physical affection is one of the <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1475-6811.1998.tb00157.x?casa_token=Rq8rCHwvKboAAAAA%3AxmDZvSXM6wTZuZzCCotRMro4nC_xcSbnw6Em8Od29q__XfYEhuwW9Iigpr2c8WlZJ_aMY4ng5m-DM40">most direct</a> and important ways that people communicate intimacy in their romantic relationships. And it seems to occur in romantic relationships all over the <a href="https://journals.sagepub.com/doi/abs/10.1177/0146167220988373?casa_token=2rLs7-9M9bAAAAAA:UduYJMPaWQmLGFZXW0YcLvaBf-Lor1jITDDSIpqVTtTVuznW7YC89p-Jp0WUtebc2UTE8-ikrrxp&amp;casa_token=2_f_mSXK3YYAAAAA:AkLcZq_uAkQ7HyQL9jCDdubu7zuseAslE864obd1OYUMR1JLq7JPDM3C7lLMJTzDHEnQwgs6kQRi">world</a>, despite cross-cultural differences in ideas of love and romance.</p> <p>People in romantic relationships report more <a href="https://link.springer.com/article/10.1007/s10919-018-0281-8">intimate physical affection</a> than singletons. They’re also more comfortable allowing their partners to touch more of their bodies than strangers or friends. For example, most people are comfortable being touched on their <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1519231112">thighs and abdomen</a> by their partner, but not by other people.</p> <p>Even how we touch our partners is different to how we touch other people. When participants in one study were asked to stroke their partner, a friend, a stranger, or an artificial arm, they did so more <a href="https://link.springer.com/article/10.1007/s10919-020-00334-2">slowly</a> with their partner. Slower strokes may may be experienced as more pleasant and <a href="https://academic.oup.com/jsm/article/14/5/645/6973562">erotic</a> than quicker strokes. Even just <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0203039">thinking</a> about physical affection from a partner evokes pleasant and erotic sensations.</p> <p>There is now strong evidence showing that physical contact is associated with better physical and mental health. One <a href="https://www.nature.com/articles/s41562-024-01841-8">review</a> of “touch interventions” – think massage – in 212 studies involving more than 13,000 participants found that physical touch benefited everything from sleep patterns to blood pressure to fatigue. Touch interventions were especially helpful in reducing pain, depression and anxiety.</p> <h2>Couple’s therapy</h2> <p>Before you rush off to book yourself a massage, you should know that much of the evidence suggests the strongest benefits come from physical affection with romantic partners. Several studies have found that, in couples, physical affection is associated with a range of <a href="https://www.sciencedirect.com/science/article/pii/S0273229711000025?casa_token=ER4aGB-3vusAAAAA:IBMtXZdEpTywjizJ4kwcOPO2HykSwgaK3GS3qYWh5JTYvWJCLW-x1I3IYDYKbzLZ9aX8QIhOLlA">physiological</a> effects, including lower blood pressure and better immune responses.</p> <p>In couples, physical affection is also associated with better psychological <a href="https://journals.sagepub.com/doi/abs/10.1177/0146167213497592?casa_token=_OtVkA13hgkAAAAA%3AU6eWWQLI4CXadtUanBR1PEGBA-Xh8en3plwOayvC4KNF_Ybi8zyzHjheM1m2XWLxjgczoQstUEEbDg&amp;journalCode=pspc">wellbeing</a>. One study found that couples who <a href="https://link.springer.com/article/10.1007/s42761-021-00093-3">sleep-touched</a> – cuddling shortly before or after sleep – felt happier and calmer in the morning, which meant they were more likely to enjoy the company of their partners.</p> <p>Physical affection – including <a href="https://link.springer.com/article/10.1007/s10508-013-0190-1?correlationId=bbd6ba1a-a372-4cae-83b3-6d9ba5704f4e&amp;error=cookies_not_supported&amp;code=dc878548-1748-44ed-bf6b-36dd348ea060">kissing</a> and <a href="https://link.springer.com/article/10.1007/s10508-014-0305-3">affection after sex</a> – is also associated with greater relationship and <a href="https://link.springer.com/article/10.1007/s10508-016-0820-5">sexual satisfaction</a>, and better ratings of one’s relationship overall, which in turn contribute to better psychological wellbeing. And even when conflicts do occur, <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0203522">hugging</a> seems to reduce levels of negative mood in couples.</p> <p>Cuddle up, because there’s more. Receiving physical affection from a partner makes us feel psychologically stronger. One study found that women showed less activation in parts of the brain that respond to threat when <a href="https://journals.sagepub.com/doi/10.1111/j.1467-9280.2006.01832.x">holding their husband’s hand</a>. Even just imagining touch from a partner can increase one’s willingness to take on <a href="https://www.sciencedirect.com/science/article/abs/pii/S0022103116302013?via%3Dihub">challenging tasks</a>.</p> <p>Another way to look at this is to examine what happens when we lose physical affection. Studies have shown that “<a href="https://onlinelibrary.wiley.com/doi/full/10.1002/ijop.12616">touch deprivation</a>” – the absence of touch – is associated with greater symptoms of depression and anxiety. Indeed, the loss of affection from others during the pandemic <a href="https://esmed.org/MRA/mra/article/view/2204">hit many people hard</a>. Among couples, a <a href="https://www.tandfonline.com/doi/abs/10.1080/10570314.2014.927071?casa_token=D34OY4K-RBIAAAAA:GY-MyGWWcZfOZgOYLmtjYbn3buO5fL1FUiD7whf1fs_aFQPGORTPwOS9Eh0ODdbeRmW32ehtrtntug">lack of physical affection</a> is associated with lower relationship satisfaction, stress, and feelings of loneliness.</p> <figure><iframe src="https://www.youtube.com/embed/ErWfdjdOah8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>There are several ways in which physical affection provides these benefits. Affectionate touch is known to activate <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1002/hbm.23679">reward centres</a> of the brain, which boosts our mood and promotes feelings of wellbeing. Touch also stimulates the release of <a href="https://www.sciencedirect.com/science/article/abs/pii/S0163638320301107?casa_token=I6GG0M3UAQEAAAAA:qSsExsEvHY9NHduwUF26okRMUm1Ls-gYHbrVNzaYgMkmS-Ohk2Y5ZvowbF2iWfpa6SO-mw6duuI">oxytocin</a>, which can strengthen social bonds and increase feelings of trust between individuals. It’s for these reasons that oxytocin is sometimes called the “cuddle chemical”.</p> <p>Physical affection also reduces levels of the stress hormone <a href="https://doi.org/10.1016/j.psyneuen.2007.03.011">cortisol</a> and reduces perceived pain, which suppress physiological stress systems.

"Why are you attacking my dad?": I'm A Celeb finalist reveals behind-the-scenes heartbreak

<p>The emotional on-air reunion between <em>I’m A Celebrity... Get Me Out of Here</em> contestant Matty J and his wife, Laura Byrne, along with their two children, Marlie-Mae and Lola Ellis, was a heartwarming moment <a href="https://www.oversixty.com.au/entertainment/tv/abrupt-viewers-stunned-by-i-m-a-celeb-winner-s-reveal" target="_blank" rel="noopener">during Sunday’s finale</a>. However, behind the scenes, Byrne has opened up about the significant challenges she faced while participating in the momentous event.</p> <p>In the lead-up to the finale, Byrne undertook an exhausting journey from Sydney to South Africa with their two young daughters. Speaking on the <em>Life Uncut</em> podcast, she detailed the arduous travel experience, which involved “three separate flights” and 24 hours of transit. “That in itself was really hard," she said. "It was like 24 hours by the time we got door to door. Midnight transfer with two children who were absolutely f***ing ropable.” </p> <p>The long journey was only the beginning of the difficulties though. Upon arrival, Byrne and the children had to share a single room with inadequate sleeping arrangements, all while preparing for a demanding day on set.</p> <p>Byrne also revealed that the experience of managing two young children on a chaotic production set was overwhelming. “I felt like I was the emotional buffer between the children and production … I felt like I’d just been flogged for days. It was hard. It was really hard for me,” she said.</p> <p>During the finale, Matty J and his fellow top three contestants – <em>Big Brother</em> star Reggie Bird and retired NRL player Sam Thaiday – were reunited with their families before participating in the final challenge. While this was an exciting moment for viewers, it was an emotionally challenging experience for the family.</p> <p>Matty J recalled the moment he had to part ways with his children soon after reuniting. “When we had our reunion, it was maybe half an hour I think where we had time together and then they’ve got to pull us apart,” he said. “The kids don’t get it, the kids don’t understand. They’re like, ‘I’ve just met my dad, and then I’ve got to go.’ And then we did that trial where we had to have s**t poured on our heads, and Lola’s in tears being like, ‘Why are you attacking my dad?’”</p> <p>Byrne explained that their children were repeatedly reunited with their father, only to be separated again. This happened three times – during the initial reunion, the final trial and then the announcement of the winner. The constant cycle of emotional reunions and abrupt separations took a toll, particularly on their youngest daughter, Lola.</p> <p>After the winner was announced, Byrne and the children expected Matty J to return home with them, but he was kept on set for several more hours. “They kept Matt on set until 6 o’clock and we went home earlier. And it was so hard on Lola particularly,” Byrne revealed. “And then I had to deal with her big emotions around ‘Why is my daddy not coming home?’ And it felt like this unfair false start.”</p> <p>She admitted that the combination of exhaustion, sleep deprivation and trying to manage the emotional needs of their children made the experience incredibly difficult. Byrne also shared that she had been against Matty J’s participation in the reality show right from the outset. “I wasn’t a supporter of it in the first place,” she admitted, reinforcing that the experience had only confirmed her concerns.</p> <p>Even Matty J himself struggled with the demands of the show. He confessed that he broke down early in his time at camp, an emotional moment that wasn’t shown on TV. “I just burst out crying, and I was like, ‘I f**king cannot do this,’” he recalled, explaining that a moment of solitude while washing dishes left him questioning his decision. “What have I f**king done? This is a nightmare.”</p> <p><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">It appears that, for the Byrne-Johnson family, what seemed like a joyful televised reunion was, in reality, a deeply exhausting and emotional ordeal.</span></p> <p><em>Images: Network 10</em></p>

Tourists explain why they love “overrated” capital cities

<p dir="ltr">A group of travellers have explained why they love some capital cities that are often dubbed as “overrated”. </p> <p dir="ltr">On a dedicated travel thread on Reddit, one person asked the question, “Which capital city gets a lot of hate that you loved visiting?” which welcomed an influx of responses. </p> <p dir="ltr">A few capital cities were mentioned several times, one of which being the Greece capital of Athens. </p> <p dir="ltr">One Reddit user said they “avoided” Athens for a long time “because all I heard was negativity about it”.</p> <p dir="ltr">However, when they “finally went”, they say they “loved it” and “can't wait to go back”. </p> <p dir="ltr">Another person said they actually “loved” the city's “gritty feel” adding, “Incredible history at every turn, delicious affordable food, fun bars, cool music venues, neighbourhoods full of character and beautiful viewpoints.”</p> <p dir="ltr">Another capital that was mentioned was the Norwegian capital of Oslo, with one person saying the Scandinavian city was perfect for a short getaway. </p> <p dir="ltr">They wrote, “I’m not advising anyone to go for a long time but for a weekend trip, it’s lovely. The seaside is great with lots of beautiful modern architecture, the old town is picturesque, lots of trendy new places to eat and drink, some old castles to walk to and in general a really nice vibe and very walkable.”</p> <p dir="ltr">Washington D.C. was also mentioned with many people defending the city, with one person claiming “it’s generally other Americans who hate it.”</p> <p dir="ltr">One person wrote of the city, “We have great museums, food, way more nature than you’d expect for a city, and incredible music and dance scenes. It’s not just insufferable bureaucracy and politics.”</p> <p dir="ltr">The Belgian capital of Brussels was also mentioned, with the city often copping a lot of flack amongst travellers. </p> <p dir="ltr">However, many were quick to defend the city, as one person wrote,”I loved Brussels, it’s beautiful in places, has amazing museums, great beer, the EU Parliament is really interesting and the Atomium is awesome.”</p> <p dir="ltr"><em>Image credits: Shutterstock </em></p> <p> </p>

‘A virtual seat at the family table’: why older people are among the biggest users of social media

According to the <a href="https://wearesocial.com/au/blog/2024/01/digital-2024/">Digital 2024 report</a>, 78.3% of Australians regularly use platforms such as Facebook and Instagram – mainly for keeping in touch with friends and family.</p> <p>Perhaps surprisingly, a large proportion of these users are older people. For example, the Digital 2024 report also shows that 21.3% of Meta’s ad audience in Australia (on Messenger, Facebook and Instagram) are 55 years or older. This makes it the second largest age group after 25–34 year olds (25.4%).</p> <p>So what does research say about how social media affects older people’s social lives and wellbeing?</p> <h2>The growing presence of older adults on social media</h2> <p><a href="https://www.digitalinclusionindex.org.au/digital-inclusion-the-australian-context-in-2023/">The digital divide is shrinking</a> as older generations embrace social media. <a href="https://www.benetas.com.au/news/digial-habits-of-older-australians">According to data from earlier this year</a>, more than 70% of Australians aged 65 and older use social media to some degree.</p> <p><a href="https://www.aarp.org/content/dam/aarp/research/surveys_statistics/technology/2023/2023-tech-trends.doi.10.26419-2Fres.00584.001.pdf">Facebook remains the most popular</a> among this demographic, serving as a gateway to reconnect with family and long-lost friends. Beyond reconnecting, <a href="https://apo.org.au/node/313717">our research indicates</a> older adults often use these platforms to share memories, participate in community groups and access news.</p> <p>This growing trend is driven by both internal and external factors. <a href="https://www.emerald.com/insight/content/doi/10.1108/oir-06-2021-0332/full/html">Research shows</a> many older users are motivated by the desire to stay connected with their families, particularly grandchildren, who often share their lives through social media.</p> <p>For others, the COVID pandemic <a href="https://www.abc.net.au/news/2020-05-18/are-we-headed-to-a-cashless-economy-post-coronavirus/12244846">accelerated the adoption of digital tools</a>, making social media a lifeline during periods of isolation.</p> <h2>Enhanced connection</h2> <p><a href="https://www.nature.com/articles/s41562-024-02048-7">A recent study</a> found positive associations between internet use and mental health among older adults in 23 countries.</p> <p>Social media, in particular, works by:</p> <p><strong>1. Maintaining family ties.</strong> Social media provides older adults with a virtual seat at the family table. By viewing photos, videos and updates, <a href="https://theconversation.com/video-chats-can-ease-social-isolation-for-older-adults-during-coronavirus-pandemic-135890">they can remain engaged with their loved ones’ lives</a>, no matter the physical distance. Platforms such as WhatsApp and Facebook Messenger are particularly popular for private family group chats, enabling older adults to exchange messages and share moments in real time.</p> <p><strong>2. Rekindling old friendships.</strong> Platforms such as Facebook have proven effective in <a href="https://www.tandfonline.com/doi/pdf/10.1080/10510974.2021.1975143?needAccess=true">reconnecting older adults with long-lost friends</a>.

Studies have shown such interactions can <a href="https://pubmed.ncbi.nlm.nih.gov/32700541/">bolster feelings of inclusion</a> and reduce loneliness, a significant concern for ageing populations.</p> <p><strong>3. Building new communities.</strong> Social media groups dedicated to specific interests such as gardening, photography or travel offer older adults opportunities to form new connections. <a href="https://www.emerald.com/insight/content/doi/10.1108/jkm-02-2021-0087/full/html">These virtual communities</a> are inclusive spaces where members exchange advice, share experiences and foster friendships based on shared hobbies.</p> <h2>Improved well-being</h2> <p>Social media’s ability to foster connection among older adults <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8465959/#B7-healthcare-09-01143">directly impacts their wellbeing</a>.</p> <p>Regular online interactions can reduce feelings of loneliness and depression, providing a sense of purpose and belonging.</p> <p><a href="https://www.tandfonline.com/doi/abs/10.1080/10410236.2020.1859722">Research shows</a> active participation, such as posting photos, is associated with a feeling of competence in older users, which is related to well-being.

This demonstrates social media platforms’ broader potential beyond social interaction.</p> <h2>Online challenges</h2> <p>Despite its benefits, social media is not without challenges for older adults.</p> <p>For some, navigating the complex interface of platforms can be intimidating. <a href="https://www.mdpi.com/2076-0760/13/9/496">Our research</a> shows half of older adults feel anxious about using communication technologies, with older women experiencing more anxiety than older men.</p> <p>Issues such as <a href="https://apo.org.au/sites/default/files/resource-files/2021-08/apo-nid313717.pdf">privacy concerns, misinformation and online scams can also create barriers to engagement</a>. Additionally, while social media facilitates connection, it <a href="https://agsjournals.onlinelibrary.wiley.com/doi/10.1111/jgs.18546">cannot replace the depth of face-to-face interactions</a>.</p> <p><a href="https://journals.sagepub.com/doi/full/10.1177/14413582231187652">Our research</a> shows those with higher digital literacy are more likely to experience the positive effects of social media because of ongoing “self-socialisation” without having to interact with others, which might undermine learning and confidence. For others, initiatives aimed at <a href="https://www.dss.gov.au/improving-digital-skills-older-australians/resource/evaluation-be-connected">improving digital skills among older adults</a> – such as digital mentoring programs – can significantly enhance their confidence and ability to engage safely online.</p> <h2>A bridge and a barrier</h2> <p>Social media can keep older adults connected.

Why the WHO has recommended switching to a healthier salt alternative

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/xiaoyue-luna-xu-1388807">Xiaoyue (Luna) Xu</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/bruce-neal-69">Bruce Neal</a>, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a></em></p> <p>This week the <a href="https://www.who.int/news-room/events/detail/2025/01/27/default-calendar/launch-of-the-who-guideline-on-the-use-of-lower-sodium-salt-substitutes">World Health Organization</a> (WHO) released new guidelines recommending people switch the regular salt they use at home for substitutes containing less sodium.</p> <p>But what exactly are these salt alternatives? And why is the WHO recommending this? Let’s take a look.</p> <h2>A new solution to an old problem</h2> <p>Advice to eat less salt (sodium chloride) is not new. It has been part of international and Australian guidelines <a href="https://www.ahajournals.org/doi/full/10.1161/HYPERTENSIONAHA.123.21343?rfr_dat=cr_pub++0pubmed&amp;url_ver=Z39.88-2003&amp;rfr_id=ori%3Arid%3Acrossref.org">for decades</a>. This is because evidence clearly shows the sodium in salt can <a href="https://www.who.int/news-room/fact-sheets/detail/salt-reduction">harm our health</a> when we eat too much of it.</p> <p>Excess sodium increases the risk of high blood pressure, which affects millions of Australians (around <a href="https://www.aihw.gov.au/reports/risk-factors/high-blood-pressure/contents/summary">one in three adults</a>). High blood pressure (<a href="https://www.healthdirect.gov.au/high-blood-pressure-hypertension">hypertension</a>) in turn increases the risk of heart disease, stroke and kidney disease, among other conditions.</p> <p>The WHO estimates <a href="https://www.who.int/news-room/events/detail/2025/01/27/default-calendar/launch-of-the-who-guideline-on-the-use-of-lower-sodium-salt-substitutes">1.9 million deaths</a> globally each year can be attributed to eating too much salt.</p> <p>The WHO recommends consuming no more than <a href="https://www.who.int/news-room/fact-sheets/detail/salt-reduction">2g of sodium daily</a>. However people eat on average more than double this, around <a href="https://www.who.int/news-room/events/detail/2025/01/27/default-calendar/launch-of-the-who-guideline-on-the-use-of-lower-sodium-salt-substitutes">4.3g a day</a>.</p> <p>In 2013, WHO member states <a href="https://iris.who.int/bitstream/handle/10665/366393/9789240069985-eng.pdf?sequence=1">committed to reducing</a> population sodium intake <a href="https://www.who.int/news/item/09-03-2023-massive-efforts-needed-to-reduce-salt-intake-and-protect-lives">by 30% by 2025</a>. But cutting salt intake has proved very hard. Most countries, including Australia, will not meet the WHO’s goal for reducing sodium intake <a href="https://www.sciencedirect.com/science/article/pii/S2161831322004690?via%3Dihub_">by 2025</a>. The WHO has since <a href="https://www.who.int/news-room/events/detail/2025/01/27/default-calendar/launch-of-the-who-guideline-on-the-use-of-lower-sodium-salt-substitutes">set the same target for 2030</a>.</p> <p>The difficulty is that eating less salt means accepting a less salty taste. It also requires changes to established ways of preparing food. This has proved too much to ask of people making food at home, and too much for the food industry.</p> <h2>Enter potassium-enriched salt</h2> <p>The main lower-sodium salt substitute is called potassium-enriched salt. This is salt where some of the sodium chloride has been replaced with potassium chloride.</p> <p>Potassium is an <a href="https://www.healthdirect.gov.au/potassium">essential mineral</a>, playing a key role in all the body’s functions. The high potassium content of fresh fruit and vegetables is one of the main reasons they’re so good for you. While people are eating more sodium than they should, many don’t get enough potassium.</p> <p>The WHO recommends a daily potassium intake of 3.5g, but on the whole, people in most countries consume significantly <a href="https://www.ahajournals.org/doi/full/10.1161/HYPERTENSIONAHA.123.21343?rfr_dat=cr_pub++0pubmed&amp;url_ver=Z39.88-2003&amp;rfr_id=ori%3Arid%3Acrossref.org">less than this</a>.</p> <p>Potassium-enriched salt benefits our health by cutting the amount of sodium we consume, and increasing the amount of potassium in our diets. Both help to <a href="https://theconversation.com/this-salt-alternative-could-help-reduce-blood-pressure-so-why-are-so-few-people-using-it-221409">lower blood pressure</a>.</p> <p>Switching regular salt for potassium-enriched salt has been shown to <a href="https://heart.bmj.com/content/108/20/1608">reduce the risk</a> of heart disease, stroke and premature death in large trials around the world.</p> <p>Modelling studies have projected that population-wide switches to potassium-enriched salt use would prevent hundreds of thousands of deaths from cardiovascular disease (such as heart attack and stroke) each year in <a href="https://www.bmj.com/content/369/bmj.m824.long">China</a> and <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.122.19072?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubme">India</a> alone.</p> <p>The key advantage of switching rather than cutting salt intake is that potassium-enriched salt can be used as a direct one-for-one swap for regular salt. It looks the same, works for seasoning and in recipes, and most people don’t notice any important <a href="https://theconversation.com/this-salt-alternative-could-help-reduce-blood-pressure-so-why-are-so-few-people-using-it-221409">difference in taste</a>.</p> <p>In the <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2105675">largest trial</a> of potassium-enriched salt to date, more than 90% of people were still using the product after five years.</p> <h2>Making the switch: some challenges</h2> <p>If fully implemented, this could be one of the most consequential pieces of advice the WHO has ever provided.</p> <p>Millions of strokes and heart attacks could be prevented worldwide each year with a simple switch to the way we prepare foods. But there are some obstacles to overcome before we get to this point.</p> <p>First, it will be important to balance the benefits and the risks. For example, people with <a href="https://www.ahajournals.org/doi/full/10.1161/HYPERTENSIONAHA.123.21343?rfr_dat=cr_pub++0pubmed&amp;url_ver=Z39.88-2003&amp;rfr_id=ori%3Arid%3Acrossref.org">advanced kidney disease</a> don’t handle potassium well and so these products are not suitable for them. This is only <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8177747/">a small proportion</a> of the population, but we need to ensure potassium-enriched salt products are labelled with appropriate warnings.</p> <p>A key challenge will be making potassium-enriched salt more affordable and accessible. Potassium chloride is more expensive to produce than sodium chloride, and at present, potassium-enriched salt is mostly sold as a niche health product at a <a href="https://publichealth.jmir.org/2021/7/e27423">premium price</a>.</p> <p>If you’re looking for it, <a href="https://www.georgeinstitute.org/switchthesalt#card-with-text-2166">salt substitutes</a> may also be called low-sodium salt, potassium salt, heart salt, mineral salt, or sodium-reduced salt.</p> <p>A <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8319774/">review published in 2021</a> found low sodium salts were marketed in only 47 countries, mostly high-income ones. Prices ranged from the same as regular salt to almost 15 times higher.</p> <p>An expanded supply chain that produces much more food-grade potassium chloride will be needed to enable wider availability of the product. And we’ll need to see potassium-enriched salt on the shelves next to regular salt so it’s easy for people to find.</p> <p>In countries like Australia, about 80% of the salt we eat comes from <a href="https://www.foodstandards.gov.au/consumer/nutrition/sodium-salt/salthowmuch">processed foods</a>. The WHO guideline falls short by not explicitly prioritising a switch for the salt used in food manufacturing.</p> <p>Stakeholders working with government to encourage food industry uptake will be essential for maximising the health benefits.<!-- Below is The Conversation's page counter tag.
