Most retirees who rent live in poverty. Here’s how boosting rent assistance could help lift them out of it

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/brendan-coates-154644">Brendan Coates</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a>; <a href="https://theconversation.com/profiles/joey-moloney-1334959">Joey Moloney</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a>, and <a href="https://theconversation.com/profiles/matthew-bowes-2316740">Matthew Bowes</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a></em></p> <p>Most Australians can look forward to a comfortable retirement. More than three in four retirees own their own home, most report feeling comfortable financially, and few suffer financial stress.</p> <p>But our new Grattan Institute <a href="https://grattan.edu.au/report/renting-in-retirement-why-rent-assistance-needs-to-rise/">report</a> paints a sobering picture for one group: retirees who rent in the private market. Two-thirds of this group live in poverty, including more than three in four single women who live alone.</p> <hr /> <p><iframe id="x2VND" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/x2VND/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <hr /> <p>Retirees who rent often have little in the way of retirement savings: more than half have less than A$25,000 stashed away. And a growing number of older Australians are at risk of becoming homeless.</p> <p>But our research also shows just how much we’d need to boost Commonwealth Rent Assistance to make housing more affordable and ensure all renters are able to retire with dignity.</p> <h2>Today’s renters, tomorrow’s renting retirees</h2> <p>Home ownership is falling among poorer Australians who are approaching retirement.</p> <p>Between 1981 and 2021, home ownership rates among the poorest 40% of 45–54-year-olds fell from 68% to just 54%. Today’s low-income renters are tomorrow’s renting retirees.</p> <p>Age pensioners need at least $40,000 in savings to afford to spend $350 a week in rent, together with the <a href="https://www.servicesaustralia.gov.au/age-pension">Age Pension</a> and <a href="https://www.servicesaustralia.gov.au/rent-assistance">Rent Assistance</a>. That’s enough to afford the cheapest 25% of one-bedroom homes in capital cities.</p> <p>But Australians who are renting as they approach retirement tend to have little in the way of retirement savings. 40% of renting households aged 55-64 have net financial wealth less than $40,000.</p> <h2>Rent assistance is too low</h2> <p>Our <a href="https://grattan.edu.au/report/renting-in-retirement-why-rent-assistance-needs-to-rise/">research</a> shows that Commonwealth Rent Assistance, which supplements the Age Pension for poorer retirees who rent, is inadequate.</p> <p>The federal government has <a href="https://ministers.treasury.gov.au/ministers/jim-chalmers-2022/speeches/budget-speech-2024-25">lifted the maximum rate of Rent Assistance</a> by 27% – over and above inflation – in the past two budgets. But the payment remains too low.</p> <p>A typical single retiree needs at least $379 per week to afford essential non-housing costs such as food, transport and energy.</p> <p>But we found a single pensioner who relies solely on income support can afford to rent just 4% of one-bedroom homes in Sydney, 13% in Brisbane, and 14% in Melbourne, after covering these basic living expenses.</p> <p>With Rent Assistance indexed to inflation, rather than low-income earners’ housing costs, the maximum rate of the payment has increased by 136% since 2001, while the rents paid by recipients have increased by 193%.</p> <h2>A boost is needed</h2> <p>Our analysis suggests that to solve this problem, the federal government should increase the maximum rate of Rent Assistance by 50% for singles and 40% for couples.</p> <p>The payment should also be indexed to changes in rents for the cheapest 25% of homes in our capital cities.</p> <p>These increases would boost the maximum rate of Rent Assistance by $53 a week ($2,750 a year) for singles, and $40 a week ($2,080 a year) for couples.</p> <p>This would ensure single retirees could afford to spend $350 a week on rent, enough to rent the cheapest 25% of one-bedroom homes across Australian capital cities, while still affording other essentials.</p> <p>Similarly, retired couples would be able to afford to spend $390 a week on rent, enough to rent the cheapest 25% of all one- and two-bedroom homes.</p> <hr /> <p><iframe id="EZBuw" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/EZBuw/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <hr /> <h2>Unlikely to push up rents</h2> <p>One common concern is that increasing Rent Assistance will just lead landlords to hike rents. But we find little evidence that this is the case.</p> <p>International studies suggest that more than five in six dollars of any extra Rent Assistance paid would benefit renters, rather than landlords.</p> <hr /> <p><iframe id="qGxQE" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/qGxQE/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <hr /> <p>In Australia, there’s little evidence that recent increases in Rent Assistance have pushed up rents.</p> <p>Our analysis of NSW rental bond lodgement data suggests areas with higher concentrations of Rent Assistance recipients did not see larger rent increases in the year after the payment was boosted.</p> <p>That’s not surprising. Rent Assistance is paid to tenants, not landlords, which means tenants are likely to spend only a small portion of any extra income on housing.</p> <p>Since rates of financial stress are even higher among younger renters, we propose that any increase to Rent Assistance should also apply to working-age households.</p> <p>Boosting Rent Assistance for all recipients would cost about $2 billion a year, with about $500 million of this going to retirees.</p> <p>These increases could be paid for by further <a href="https://grattan.edu.au/report/super-savings-practical-policies-for-fairer-superannuation-and-a-stronger-budget/">tightening superannuation tax breaks</a>, <a href="https://grattan.edu.au/report/housing-affordability-re-imagining-the-australian-dream/">curbing negative gearing and halving the capital gains tax discount</a>, or counting more of the value of the family home in the Age Pension assets test.<!-- Below is The Conversation's page counter tag.

Restless legs syndrome is incurable – here’s how to manage the symptoms

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>Restless legs syndrome (RLS), also known as <a href="https://www.ninds.nih.gov/health-information/disorders/restless-legs-syndrome#toc-what-is-restless-legs-syndrome-rls-">Willis-Ekbom Disease</a>, is a neurological condition that affects <a href="https://pubmed.ncbi.nlm.nih.gov/38843039/">about 7%</a> of people.</p> <p>Typical symptoms include an irresistible urge to move your legs, alongside sensations of aching, crawling, creeping, itching, pulling or throbbing. Until the age of 35, the condition is <a href="https://cks.nice.org.uk/topics/restless-legs-syndrome/background-information/prevalence/">equally common</a> in men and women, but after that age, RLS affects <a href="https://www.racgp.org.au/getattachment/87576673-c695-48f6-a806-065da7e5fcc7/Restless-legs-syndrome.aspx">twice the number</a> of women than men.</p> <p>Each person’s condition is categorised as mild, moderate, severe or very severe according to the <a href="https://biolincc.nhlbi.nih.gov/media/studies/masm/IRLS.pdf?link_time=2019-07-07_21:09:19.282153">international rating scale</a>, which measures the effects of RLS on limb discomfort and sleep disruption, as well as frequency of symptoms.</p> <p>RLS symptoms have a 24-hour cycle known as a <a href="https://www.sciencedirect.com/science/article/pii/S0301008205001371">circadian rhythm</a>. Symptoms tend to peak at night, coinciding with the body’s <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/ana.10843">increase in melatonin release</a>. Melatonin reduces dopamine – the brain chemical that affects movement and mood – to help us sleep but, because dopamine helps control muscles, low dopamine levels can cause involuntary movements.</p> <p>There is <a href="https://cks.nice.org.uk/topics/restless-legs-syndrome/diagnosis/investigations/">no test for RLS</a>. Diagnosis is based on symptoms and medical history. Primary RLS runs in families – there are <a href="https://pubmed.ncbi.nlm.nih.gov/12764067/">genetic</a> links to a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2653903/">number of chromosomes</a>. RLS has an autosomal dominant inheritance pattern, meaning you only need one “defective” copy to present with symptoms. Some cases, however, develop with no known cause.</p> <p>Other people may develop “secondary” RLS as a result of other conditions, such as <a href="https://pubmed.ncbi.nlm.nih.gov/34732752/">iron deficiency anaemia</a>, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6464953/">chronic kidney disease</a>, <a href="https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(22)00087-6/fulltext">diabetes</a>, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3900617/">Parkinson’s disease</a>, <a href="https://onlinelibrary.wiley.com/doi/10.1111/1756-185X.14710">rheumatoid arthritis</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/32483857/">underactive thyroid gland</a>, and <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2952743/">fibromyalgia</a>. While primary RLS is more common than secondary, the latter is usually <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6073788/">more severe and progresses more rapidly</a>.</p> <figure><iframe src="https://www.youtube.com/embed/hnTKtp5PZGo?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Risk factors</h2> <p>Age seems to be a risk factor for RLS. In 2000, <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/485413">a study found</a> that 10% of adults aged 30 to 79 have RLS, increasing to 19% of those over the age of 80. However, understanding of the condition has improved since that study was conducted, so it’s likely these figures are higher – particularly in children, where <a href="https://mecp.springeropen.com/articles/10.1186/s43045-022-00226-9">some RLS symptoms</a> have been confused with “growing pains” or ADHD in the past.</p> <p>Women have an increased chance of developing RLS. Approximately <a href="https://pubmed.ncbi.nlm.nih.gov/29169861/">one in five women</a> will suffer from restless legs at some point, and some studies suggest as many as <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5562408/">one in three women</a> are affected. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4478054/">Women are</a> <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9176156/">more likely</a> to suffer from <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4478054/">other comorbidities</a> that affect the central nervous system, such as <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10982394/">anxiety, depression</a> and <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8634649/">migraine</a>, which may be linked to the development of RLS.</p> <p>Pregnancy is another risk factor. The further you are through the trimesters, the higher your chance of being affected BY RLS – with 8%, 16% and 22% of women suffering through their respective first, second and third trimesters. Multiple pregnancies increase the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5562408/">risk of pregnancy-related RLS</a>, and research has found that women who’ve given birth may have a <a href="https://www.sciencedirect.com/science/article/pii/S1389945709001890">higher incidence of RLS</a> in later life, compared with women of the same age who haven’t given birth.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4751426/">Obesity</a> is also considered a risk factor for RLS. One study showed that each 5kg/m² increase in body mass index increased the likelihood of developing RLS <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2677487/">by 31%</a>.</p> <h2>Triggers and treatments</h2> <p>Research has shown smoking and alcohol consumption seem to <a href="https://jcsm.aasm.org/doi/10.5664/jcsm.11390">make RLS worse</a>, so <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4751426/">lifestyle changes</a> such as stopping smoking and drinking alcohol can help manage symptoms.</p> <figure><iframe src="https://www.youtube.com/embed/x1hizeYdBFk?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p><a href="https://movementdisorders.onlinelibrary.wiley.com/doi/full/10.1002/mdc3.13833">Research has also found</a> that exercise and stretching is beneficial for symptom relief or reduction – although <a href="https://onlinelibrary.wiley.com/doi/10.1111/jsr.13980">study participants</a> suggest that morning exercise is more effective for improving symptoms, while evening exercise can make restless legs worse. Patients with secondary forms of RLS, lower BMI and less severe cases of the condition <a href="https://www.sciencedirect.com/science/article/pii/S1389945724005409">may benefit the most</a> from lifestyle changes to manage symptoms.</p> <p>Also, treatment of underlying issues can also alleviate or reduce some of the symptoms. For instance, iron deficiency anaemia <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5434142/">reduces</a> dopamine levels, which can lead to restless legs. Iron supplements <a href="https://jcsm.aasm.org/doi/10.5664/jcsm.7810">may benefit</a> some sufferers – but <a href="https://academic.oup.com/sleep/article/47/7/zsae022/7585953">the evidence</a> is mixed so supplements won’t help everyone.</p> <p>In terms of medication, research has found that neurological therapies, such as the anticonvulsant Gabapentin – usually prescribed as a treatment for epilepsy – can improve <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2878254/">symptoms</a> and overall <a href="https://pubmed.ncbi.nlm.nih.gov/27067343/">quality of life</a> for those suffering with restless legs. <a href="https://pubmed.ncbi.nlm.nih.gov/26456872/">These therapies</a> target <a href="https://www.sciencedirect.com/science/article/abs/pii/B9780123745309000073">nerve cells</a> in the brain, <a href="https://www.sciencedirect.com/science/article/abs/pii/B9780123745309000073">reducing</a> <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3349794/">their activity</a>.</p> <p>Other medicines – known as dopamine agonists – <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3543080/">activate dopamine receptors in the brain</a> to control movement. They are primarily used as a <a href="https://www.parkinsons.org.uk/information-and-support/dopamine-agonists-pramipexole-ropinirole">treatment</a> for Parkinson’s disease and are effective in <a href="https://pubmed.ncbi.nlm.nih.gov/38761607/">managing</a> <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8908466/">symptoms</a> of RLS. However, they can disturb your sleep pattern and may <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5762774/">increase impulse control disorders</a>, and are not <a href="https://cks.nice.org.uk/topics/restless-legs-syndrome/management/management/">recommended during pregnancy</a> or breastfeeding as they can <a href="https://www.ncbi.nlm.nih.gov/books/NBK551686/">inhibit lactation</a>.</p> <p>While there may not be a cure for RLS, there is hope for sufferers – and options for managing and reducing symptoms.<!-- Below is The Conversation's page counter tag.

Want your loved ones to inherit your super? Here’s why you can’t afford to skip this one step

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/tobias-barkley-1271340">Tobias Barkley</a>, <a href="https://theconversation.com/institutions/la-trobe-university-842">La Trobe University</a></em></p> <p>What happens to our super when we die? Most Australians have superannuation accounts but about <a href="https://www.austlii.edu.au/cgi-bin/viewdoc/au/journals/SydLawRw/2024/10.html#Heading24">one in five</a> of us die before we can retire and actually enjoy that money.</p> <p>If we do die early our money is paid out as super “death benefits”. They can be substantial. Even people who die young can have $200,000–$300,000 of death benefits through <a href="https://moneysmart.gov.au/how-life-insurance-works/insurance-through-super">super life insurance</a>.</p> <p>Death benefits have recently been in the news for all the wrong reasons. Last week <a href="https://ministers.treasury.gov.au/ministers/jim-chalmers-2022/media-releases/mandatory-service-standards-superannuation-industry">the Treasurer Jim Chalmers</a> expressed concern about delays paying out death benefits.</p> <p><a href="https://lawcouncil.au/resources/submissions/proposed-reform-to-superannuation-death-benefits">The Law Council</a> is concerned people do not have enough control over how death benefits are distributed. <a href="https://www.watoday.com.au/national/western-australia/championing-for-molly-perth-mum-s-milestone-in-her-quest-for-justice-20241206-p5kwiu.html">Others are devastated</a> about death benefits being paid to alleged violent partners.</p> <h2>How can you decide who gets your unspent super?</h2> <p>Our first thought might be writing it in our will. However, super is not covered by our will as it does not become part of our <a href="https://www.austlii.edu.au/cgi-bin/viewdoc/au/cases/cth/FCA/2001/1535.html">deceased estate</a>.</p> <p>Instead, death benefits are distributed by the trustee of your superannuation fund. Under the law, there are two main mechanisms controlling distribution: <a href="https://www.australiansuper.com/superannuation/access-your-super-early/nominate-a-beneficiary#:%7E:text=A%20binding%20nomination%20instructs%20AustralianSuper,the%20date%20we%20accept%20it.&amp;text=Lapsing%20binding%20nomination%20%E2%80%93%20This%20nomination,date%20you%20sign%20the%20form.">binding nominations</a> and the trustee’s discretion.</p> <p>Every super member has the option to create a binding nomination. It’s like a will for your super that the super trustee is obliged to follow. It also needs two witnesses to execute it. However, there are actually more ways for a binding nomination to fail than for a will to fail.</p> <p>The law only allows you to nominate certain people: your “<a href="https://www.lawsociety.com.au/resources/resources/my-practice-area/elder-law/superannuation-FAQs#collapse_165">dependants</a>” or your estate. If you nominate anyone else your entire nomination stops being binding. Plus, unlike wills, there is no way to fix execution errors. Also, many binding nominations expire after three years.</p> <p>If you don’t have a binding nomination, then the trustee can choose who your death benefit goes to. There are two main mechanisms controlling how the trustee chooses who gets your death benefit.</p> <p>First, <a href="https://treasury.gov.au/sites/default/files/2019-03/c2019-t371937-discussion-paper.pdf">legislation</a> requires the trustee to give the death benefit to your dependants or deceased estate before anyone else. This means that your parents, for example, will only receive something if you have no children, partner or other dependants.</p> <p>Second, decisions made by trustees can be disputed by complaining to the <a href="https://www.afca.org.au/">Australian Financial Complaints Authority (AFCA)</a>. The authority has a rigid approach to who should get death benefits and trustees usually follow this course of action.</p> <p><a href="https://openjournals.library.sydney.edu.au/SLR/article/view/20199">Research I’ve done with Xia Li</a> of La Trobe University reveals what AFCA does in practice.</p> <p>Most crucially, people’s wishes expressed in non-binding nominations were essentially ignored. Our research found there was no statistically significant association between being nominated in a non-binding nomination and receiving any of the death benefit. This was true even for recent nominations.</p> <p>Other factors the complaints authority ignores are family violence and financial need. In one case, five daughters provided evidence, including a police report, that their deceased mother was a victim of violence perpetrated by her new partner. <a href="https://service02.afca.org.au/CaseFiles/FOSSIC/701195.pdf">In keeping with the Federal Court, AFCA gave the alleged perpetrator</a> everything because he alone would have benefited from the deceased’s finances if she had lived.</p> <p>In another case, <a href="https://service02.afca.org.au/CaseFiles/FOSSIC/874050.pdf">the deceased’s adult son received nothing</a> despite living with disability and “doing it tough”. He had refused financial help so was not financially dependent. AFCA gave everything to the partner.</p> <p>AFCA ignores these factors because of one key issue. It places “<a href="https://service02.afca.org.au/CaseFiles/FOSSIC/832049.pdf">great weight</a>” on whether beneficiaries are financially dependent on the deceased.</p> <p>This means when choosing between a financial dependent – such as a new partner who shares home expenses with the deceased, and non-financial dependants, such as most adult children – AFCA will almost always give everything to the spouse.</p> <p>Relying on financial dependence can be arbitrary. Unlike in family law, a de facto partner <a href="http://www.austlii.edu.au/cgi-bin/viewdoc/au/legis/cth/consol_act/sia1993473/s10.html#spouse">does not need to be living with you for two years</a> before becoming entitled. For example, <a href="https://service02.afca.org.au/CaseFiles/FOSSIC/753556.pdf">in one case AFCA gave a partner of possibly only seven months</a> (and 41 years younger than the deceased) everything and the deceased’s three children aged 27–33 nothing.</p> <p>Also, AFCA treats any regular payment that supports daily living as financial dependence. For example, <a href="https://service02.afca.org.au/CaseFiles/FOSSIC/714258.pdf">a son paying A$100 a week board to parents means both parents are financially dependent on the son</a>. In another case, payments from the deceased to his brother of $5,000, $7,000 and $5,000 made over a year <a href="https://service02.afca.org.au/CaseFiles/FOSSIC/842323.pdf">was not financial dependence because they were irregular</a>.</p> <p>The whole process is slow. The average time it takes to resolve a death benefit case that goes to AFCA is nearly <a href="https://www.austlii.edu.au/cgi-bin/viewdoc/au/journals/SydLawRw/2024/10.html#Heading248">three years and the longest case I’ve seen took over six</a>.</p> <p>The only thing that you can do that will make a difference is execute a binding nomination; non-binding nominations are worthless.</p> <p>But take care to execute your binding nomination correctly (get legal advice) and leave reminders for yourself to review it every three years.<!-- Below is The Conversation's page counter tag.

Dave Hughes spills on worst A-list celeb interview

<p>Dave Hughes has revealed the "rudest" A-list celebrity he's ever interviewed in the latest episode of  <em>I’m A Celebrity … Get Me Out of Here!</em></p> <p>The radio star was talking about all his celebrity interviews throughout the years with campmate Max Balegde, who then asked him: “I want you to be honest – who was the rudest?” </p> <p>“If we’re going to be honest … it hurts me to say it, but it’s … Ben Stiller. I was a big fan, and he was just a pain in the a**e," Hughes replied. </p> <p>Hughes then joked that he might've  “ruined his Hollywood career” by calling out the A-list actor and director known for films like <em>Zoolander </em>and <em>Meet the Parents</em>. </p> <p>The radio broadcaster didn't reveal when he'd encountered Stiller or why the actor was a "pain in the a**e" . </p> <p>In the latest episode of <em>I’m A Celebrity … Get Me Out of Here!</em> former MAFS star Samantha Moitzi was the first of this season's contestants to be evicted from the jungle. </p> <p>Last week, Aussie TV legend Sigrid Thornton was the latest celeb to join the show in its 11th season. </p> <p>It's the first time the actress appeared in a reality show during her 40-year career, telling <em>news.com.au</em>: “I felt like if I was going to say yes to a challenge like this, then this was the time for me. I mean, I’ve never done reality television; I’ve never done anything remotely like this.”</p> <p>“But I don’t hold any particular judgement around it; I’ve removed all potential judgement because I don’t know what it’s going to be. All I know is that it will be extraordinary, exciting, unexpected, and I hope a little bit wonderful.”</p> <p><em>Image: I'm A Celeb/ 10</em></p> <p> </p>

Why we get less narcissistic with age

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/ava-green-1396648">Ava Green</a>, <a href="https://theconversation.com/institutions/city-st-georges-university-of-london-1047">City St George's, University of London</a></em></p> <p>There’s a perception that today’s youth are extremely narcissistic – fame-obsessed, selfish and vain. In fact, studies show this is <a href="https://journals.sagepub.com/doi/abs/10.1177/2167696814522620?journalCode=eaxa">a common view</a> of young people, regardless of the times we live in. But are young people really more narcissistic? New research reveals that, as people age, <a href="https://psycnet.apa.org/fulltext/2025-00409-001.html">they do tend to become less narcissistic</a>.</p> <p>Narcissism is a complex, <a href="https://theconversation.com/narcissism-why-its-less-obvious-in-women-than-in-men-but-can-be-just-as-dangerous-231392">multi-dimensional personality trait</a>, which captures features beyond vanity and self-absorption. Emerging <a href="https://doi.org/10%20.1177/09637214211044109">research</a> suggests there are <a href="https://doi.org/10.1111/jopy.12464">three different features</a> (called “dimensions”) of narcissism: agentic, antagonistic and neurotic.</p> <p>Agentic narcissism involves the need for admiration and feelings of superiority. Antagonistic narcissism is characterised by the exploitation of, and a lack of empathy towards, other people. Finally, neurotic narcissism refers to being sensitive and having difficulties regulating one’s emotions.</p> <p>In order to fully understand how narcissism develops, the new study looked at all the three features. They analysed data from 51 longitudinal studies (meaning studies which follow participants over time), all of which measured how participants’ levels of narcissism changed. The researchers coded whether each study measured one or more of three different dimensions of narcissism.</p> <p>To select the studies, the team used the American Psychiatric Association (APA) PsychInfo database of papers, searching for terms including “narcissism” and “narcissistic”. Each article was reviewed by two coders who were not part of the research team. The coders independently selected the studies based on details including sample size, gender ratio, measurement used, and the country in which the sample was collected.</p> <p>This robust procedure generated a large dataset which comprised of 37,247 participants (52% female) ranging from ages eight to 77 years. The majority of the participants were from western Europe, the US and Canada.</p> <p>Overall, the researchers found that all three dimensions of narcissism declined across the life span. There was a small decline for agentic narcissism and a moderate reduction for antagonistic and neurotic narcissism. The rate of change did not differ based on gender, age or birth cohort.</p> <p>Interestingly, the researchers also found that people’s narcissism relative to that of their peers remained consistent over the life span. In other words, people who were more narcissistic than average as children remained more narcissistic than average as adults.</p> <h2>Changing roles</h2> <p>What, then, are the mechanisms involved in people becoming less narcissistic as they go through life? One possible factor is to do with changing social roles across our lifespan. It is important to remember that narcissism exists along a spectrum, with the lower end being helpful (a healthy balance of self-esteem and confidence) and the higher end being unhelpful and malignant (fluctuating self-esteem, aggression and lack of empathy).</p> <p>It is possible that our <a href="https://psycnet.apa.org/record/2008-11667-014">personalities adapt</a> when we make the transition into adulthood – which involves important individual and social responsibilities such as commitment to a relationship, leadership roles, or becoming a parent. After all, it is hard to successfully look after children or managing other people if you are too focused on yourself.</p> <p>Even in old age, narcissism continues to decline. That may be because people tend to follow paths which encourages altruistic values as opposed to egoistic values, such as commitment to their family and grandchildren. By this age, most people have probably also learned the hard way the punishing consequences of being hostile to others.</p> <p>This view is supported by <a href="https://journals.sagepub.com/doi/10.1111/j.1467-8721.2008.00543.x">other research</a> suggesting that people develop more mature personality features in general over time, including becoming more emotionally stable, conscientious (hardworking and dutiful) and agreeable (kind and altruistic). As narcissism is considered to be the opposite of maturity, we expect, in theory, that features of narcissism (particularly the antagonistic and neurotic dimensions) to decrease across the life span.</p> <p>However, narcissism can increase over time in some people. Research shows that some aspects of narcissism, such as exploitation of others and lack of empathy, can increase when people assume positions of power. This is <a href="https://iaap-journals.onlinelibrary.wiley.com/doi/abs/10.1111/j.1464-0597.2006.00226.x">particularly relevant</a> at work and <a href="https://www.sciencedirect.com/science/article/abs/pii/S0191886920304360">in relationships</a>.</p> <p>And let’s not forget that some people are simply just more narcissistic than others. Just because you’re 70 doesn’t mean you can’t be self-centered, it just means you might be less narcissistic than you once were.</p> <p>This may be partly down to genetics, but it may also be the case that certain environments exacerbate existing features of narcissism. For instance, certain parenting styles – including being neglectful, overprotective, and/or providing excessive praise by putting the child on a pedestal – have <a href="https://www.sciencedirect.com/science/article/abs/pii/S0191886920304359">all been linked</a> to children developing narcissism in adulthood, suggesting a good balance is key.</p> <p>It is important to understand more fully how narcissism changes across life. That is not least because we know that it can have a detrimental effects on the individual and the people around them.<!-- Below is The Conversation's page counter tag.

Vitamin B6 is essential – but too much can be toxic. Here’s what to know to stay safe

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/vasso-apostolopoulos-105605">Vasso Apostolopoulos</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> and <a href="https://theconversation.com/profiles/jack-feehan-1239419">Jack Feehan</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>In recent weeks, <a href="https://www.abc.net.au/news/2025-01-08/vitamin-b6-toxicity-peripheral-neuropathy-health-supplements/104793006">reports have been circulating</a> about severe reactions in people who’ve taken over-the-counter vitamin B6 supplements.</p> <p>Vitamin B6 poisoning can injure nerves and lead to symptoms including numbness, tingling and even trouble walking and moving.</p> <p>In some cases, those affected <a href="https://www.abc.net.au/news/2025-01-28/vitamin-b6-toxicity-cases-rise-vitamins-supplements-tga-review/104863232">didn’t know the product contained</a> any vitamin B6.</p> <p>So what is vitamin B6, where is it found and how much is too much? Here’s what you need to know about this essential nutrient.</p> <h2>What is vitamin B6?</h2> <p>Vitamin B6 (also known as pyridoxine) is a group of six compounds that share a similar chemical structure.</p> <p>It is an essential nutrient, meaning we need it for normal body functions, but we can’t produce it ourselves.</p> <p><a href="https://www.eatforhealth.gov.au/nutrient-reference-values/nutrients/vitamin-b6">Adults aged 19–50</a> need 1.3mg of vitamin B6 per day. The recommended dose is lower for teens and children, and higher for those aged 51 and over (1.7mg for men and 1.5mg for women) and people who are breastfeeding or pregnant (1.9mg).</p> <p>Most of us get <a href="https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-b/">this in our diet</a> – largely from animal products, including meat, dairy and eggs.</p> <p>The vitamin is also available in a range of different plant foods, including spinach, kale, bananas and potatoes, so deficiency is <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8150266/">rare</a>, even for vegetarians and vegans.</p> <p>The vitamin B6 we consume in the diet is inactive, meaning the body can’t use it. To activate B6, the liver transforms it into a compound called pyridoxal-5’-phosphate (PLP).</p> <p>In this form, vitamin B6 helps the body with more than 140 cellular functions, including building and breaking down proteins, producing red blood cells, regulating blood sugar and supporting brain function.</p> <p>Vitamin B6 is important for <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6071262/">overall health</a> and has also been associated with reduced <a href="https://pubmed.ncbi.nlm.nih.gov/28376200/">cancer</a> risk and <a href="https://www.sciencedirect.com/science/article/abs/pii/S0098299716300395">inflammation</a>.</p> <p>Despite being readily available in the diet, vitamin B6 is also widely included in various supplements, multivitamins and other products, such as Berocca and energy drinks.</p> <h2>Should we be worried about toxicity?</h2> <p>Vitamin B6 toxicity is extremely rare. It <a href="https://europepmc.org/article/nbk/nbk470579?crsi=6624972170&amp;cicada_org_src=healthwebmagazine.com&amp;cicada_org_mdm=direct&amp;client=bot">almost never occurs from dietary intake alone</a>, unless there is a genetic disorders or disease that stops nutrient absorption (such as coeliac disease).</p> <p>This is because all eight vitamins in the B group are water-soluble. If you consume more of the vitamin than your body needs, it can be excreted readily and harmlessly in your urine.</p> <p>However, in some rare cases, <a href="https://pubmed.ncbi.nlm.nih.gov/37447150/">excessive vitamin B6</a> accumulates in the blood, resulting in a condition called peripheral neuropathy. We’re still not sure why this occurs in some people but not others.</p> <p>Peripheral neuropathy <a href="https://my.clevelandclinic.org/health/diseases/14737-peripheral-neuropathy">occurs when the sensory nerves</a> – those outside our brain and spinal cord that send information to the central nervous system – are damaged and unable to function. This can be caused by a wide range of diseases (and is most well known in type 2 diabetes).</p> <p>The most common symptoms are numbness and tingling, though in some cases patients may experience difficulty with balance or walking.</p> <p>We don’t know exactly how excess vitamin B6 causes peripheral neuropathy, but it is thought to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8483950/">interfere with how the neurotransmitter GABA</a> sends signals to the sensory nerves.</p> <p>Vitamin B6 can cause permanent damage to nerves. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10343656/">Studies have shown</a> symptoms improved when the person stopped taking the supplement, although they didn’t completely resolve.</p> <h2>What is considered excessive? And has this changed?</h2> <p><a href="https://www.cureus.com/articles/199499-vitamin-b6-toxicity-secondary-to-daily-multivitamin-use-a-case-report#!/">Toxicity usually occurs</a> only when people take supplements with high doses of B6.</p> <p>Until 2022, only products with more than 50mg of vitamin B6 were required to display a warning about peripheral neuropathy. But the <a href="https://www.tga.gov.au/news/safety-updates/peripheral-neuropathy-supplementary-vitamin-b6-pyridoxine">Therapeutic Goods Administration lowered this</a> and now requires any product containing more than 10mg of vitamin B6 to carry a warning.</p> <p>The Therapeutic Goods Administration has also halved the daily upper limit of vitamin B6 a product can provide – from 200mg to 100mg.</p> <p>These changes followed a review by the administration, after receiving 32 reports of peripheral neuropathy in people taking supplements. Two thirds of these people were taking less than 50mg of vitamin B6.</p> <p>The <a href="https://www.tga.gov.au/news/safety-updates/peripheral-neuropathy-supplementary-vitamin-b6-pyridoxine#what-should-health-professionals-do">Therapeutic Goods Administration acknowledges</a> the risk varies between individuals and a lot is unknown. Its review could not identify a minimum dose, duration of use or patient risk factors.</p> <h2>But I thought B vitamins were good for me?</h2> <p>Too much of anything can cause problems.</p> <p>The updated guidelines are likely to significantly lower the risk of toxicity. They also make consumers more aware of which products contain B6, and the risks.</p> <p>The Therapeutic Goods Administration will continue to monitor evidence and revise guidelines if necessary.</p> <p>While vitamin B6 toxicity remains very rare, there are still many questions about why some people get peripheral neuropathy with lower dose supplements.</p> <p>It could be that some specific vitamin B compounds have a stronger effect, or some people may have genetic vulnerabilities or diseases which put them <a href="https://www.sciencedirect.com/science/article/pii/S2161831322004781">at higher risk</a>.</p> <h2>So what should I do?</h2> <p>Most people don’t need to actively seek vitamin B6 in supplements.</p> <p>However, many reports to the Therapeutic Goods Administration were of vitamin B6 being added to supplements labelled as magnesium or zinc – and some weren’t aware they were consuming it.</p> <p>It is important to always check the label if you are taking a new medicine or supplement, especially if it hasn’t been explicitly prescribed by a health-care professional.</p> <p>Be particularly cautious if you are taking multiple supplements. While one multivitamin is unlikely to cause an issue, adding a magnesium supplement for cramping, or a zinc supplement for cold and flu symptoms, may cause an excessive vitamin B6 dose over time, and increase your risk.</p> <p>Importantly, pay attention to symptoms that may indicate peripheral neuropathy, such as pins and needles, numbness, or pain in the feet or hands, if you do change or add a supplement.</p> <p>Most importantly, if you need advice, you should talk to your doctor, dietitian or pharmacist.<!-- Below is The Conversation's page counter tag.

Tonsils can grow back after they’ve been removed – here’s which other body parts can regenerate

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>The human body is composed of over <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6085824/">37 trillion cells</a>, each with a limited lifespan. These cells are continuously replaced to maintain organ and system function. Yet over time, or as a result of damage, the number of functioning cells can decrease to a level that causes symptoms or even organ failure.</p> <p>Regeneration of organs and systems is a scientific holy grail that relies on <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9973391/">stem cells</a>, but due to their limited number and slow division rate, this isn’t a practical route to organ regeneration. It would take many years to repopulate all the cell types needed.</p> <p>However, some people see organs “reappear”, like <a href="https://edition.cnn.com/2025/01/02/health/tonsils-regrow-sore-throat/index.html">Katy Golden</a> who had her tonsils removed for a second time as an adult after they grew back over 40 years.</p> <p>One reason that tonsils may grow back is that one of the operations to remove them is a <a href="https://pubmed.ncbi.nlm.nih.gov/22431869/">partial tonsillectomy</a>. Only removing part of the tonsils leads to a quicker recovery and fewer complications, but around <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5639321/">6% of children may see regrowth</a>, which may require further surgery in later life.</p> <p>Most people associate organ regrowth and regeneration with the liver. As little as <a href="https://www.nih.gov/news-events/nih-research-matters/cells-maintain-repair-liver-identified">10% of the liver</a> can regrow into a fully functioning liver. This is also how partial liver transplants allow the <a href="https://bmcsurg.biomedcentral.com/articles/10.1186/s12893-019-0606-5">donor to “regrow”</a> a normal sized and fully functioning liver.</p> <p>One organ that has a surprising capacity to regenerate is the spleen and sometimes it can regenerate without people realising.</p> <p>The spleen is a high-risk organ for injury and is the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4056798/">most commonly injured organ</a> in blunt abdominal trauma during traffic collisions, sporting injuries or trivial activities such as <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8551460/">bumping into furniture</a>.</p> <p>The spleen is at high risk because it has lots of blood vessels and hence lots of blood, but is only surrounded by a <a href="https://pubmed.ncbi.nlm.nih.gov/31623879/">thin capsule</a> that can tear in trauma, allowing blood to leak out. This can <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6783166/">result in death</a> if not treated promptly.</p> <p>What may also happen is small pieces of the spleen – sometimes just a few cells – can become free in the abdomen and go on to “grow” where they settle – termed <a href="https://ajronline.org/doi/10.2214/AJR.11.7896">splenosis</a>, going on to have <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4762861/">similar functional activity</a> to a mature, normally located spleen. This can be beneficial for those who have to have their spleen removed due to traumatic injury, with some reports suggesting regeneration in up to <a href="https://pubmed.ncbi.nlm.nih.gov/2603609/">66% of patients</a>.</p> <p>In the last few years, our lungs have also been shown to have regenerative capacity. It is well known that smoking and other pollutants <a href="https://www.ncbi.nlm.nih.gov/books/NBK53021/">destroy the alveoli</a> (tiny air sacs) where oxygen is passed to the blood. Stopping smoking has been shown to allow cells that have avoided damage from the cancer-causing chemicals in tobacco smoke to help <a href="https://www.nature.com/articles/s41586-020-1961-1">regenerate and repopulate</a> the lining of parts of the airways with healthy cells.</p> <p>Where a lung has been removed, the remaining lung has to adapt to support the tissues of the body and ensure enough oxygen gets to them. Studies have shown that the remaining lung <a href="https://pubmed.ncbi.nlm.nih.gov/22808959/">increases the number of alveoli</a> it has, rather than the remaining alveoli compensating by getting bigger to take up more oxygen.</p> <p>It isn’t just organs inside that regenerate. One organ that constantly does so on a humongous scale is the skin.</p> <p>As the largest organ, it has multiple barrier functions to keep things such as <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4529263/">water in</a> and <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6283644/">germs out</a>. With a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0378517322004057">surface area of almost 2m²</a>, the skin requires a significant amount of regeneration to replenish the 500,000,000 cells that are lost each day – that’s over <a href="https://pubmed.ncbi.nlm.nih.gov/15541634/">2g of skin cells per day</a>.</p> <h2>Tissue regeneration is much more common</h2> <p>One of the most active regenerative tissues is the endometrial lining of the uterus which is shed every 28 days as part of the menstrual cycle and goes through about <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10308170/">450 cycles</a> of this during a woman’s life.</p> <p>This layer varies between <a href="https://pubs.rsna.org/doi/10.1148/rg.2017170008">0.5 and 18mm in thickness</a> depending on the stage of the menstrual cycle, the <a href="https://journals.physiology.org/doi/full/10.1152/physrev.00031.2019">functional cells</a> that are lost along with the blood from vessels that support a fertilised egg if it implants.</p> <p>Men’s genitalia can also show regeneration. <a href="https://www.nhs.uk/contraception/methods-of-contraception/vasectomy-male-sterilisation/what-is-it/">Vasectomy</a>, which removes a piece of the tube (<a href="https://www.cancer.gov/publications/dictionaries/cancer-terms/def/vas-deferens">vas deferens</a>) connecting the testes to the openings in the urethra, is used to reduce the chance of pregnancy by preventing sperm moving from the testes out of the penis.</p> <p>However, the cut ends of the ducts have shown regenerative capacity and reconnected. Some sections, where <a href="https://jamanetwork.com/journals/jamasurgery/article-abstract/536907">up to 5cm</a> has been restricted or removed, have shown regeneration, even through <a href="https://bmcurol.biomedcentral.com/articles/10.1186/1471-2490-6-25">scar tissue</a>. This “recanalisation” can result in unexpected pregnancies.</p> <p>Bone is another tissue that can regenerate. If you’ve ever broken a bone, you’ll know that it repairs so that (eventually) you will regain function.</p> <p>This process of repairing the break takes six to eight weeks. But the process of regenerating the bone architecture and strength <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5365304/">continues for months and years</a> beyond this date.</p> <p>However, with <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6667184/">increasing age</a> and in <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5643776/">post-menopausal woman</a>, this process slows and the bone may not regenerate to its <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6667184/">previous strength</a> or <a href="https://pubmed.ncbi.nlm.nih.gov/15763602/">structure</a>.</p> <p>Where paired organs exist and one is lost, there is good evidence that the remaining organ can increase its functional ability to help the body cope with maintaining function. For example, when one kidney is removed, the remaining kidney <a href="https://www.kidneyregistry.com/for-donors/kidney-donation-blog/what-changes-after-kidney-donation/">enlarges</a> to handle the extra workload, filtering blood and eliminating waste efficiently.</p> <p>Although organ regeneration is rare, it does happen and typically takes years to manifest because organs are complex structures. Work continues to try to understand how scientists can develop this knowledge to help with the shortage of donor organs. Thankfully, tissue regeneration happens much more often than many people might suppose, and it is a much-needed part of staying alive.<!-- Below is The Conversation's page counter tag.

How I'm A Celebrity producers keep cast anonymous

<p><em>I'm a Celebrity... Get Me Out Of Here! </em>has been back on Aussie screens for a week, and now an inside source has revealed how everything works. </p> <p>Speaking to <em>Yahoo Lifestyle</em>, the source revealed that the show will be dropping one more celebrity into the jungle, this time "a 'famous' Australian actress that is known internationally," with the code name 'Seal'. </p> <p>The code names are an essential part of ensuring that the celebrities stay anonymous before they go into the jungle, with this year's theme for code names being animals you would find in the ocean. </p> <p>"Network 10 created codenames that allow producers to get the ‘celebrities’ into 'the jungle' without worrying about who hears their name," the insider said.</p> <p>"Producers have been referring to Hughesy as 'the dolphin' for weeks," they said. </p> <p>They cited a few other examples including: Matty J who was given the code name Manta-Ray, Nicky Buckley had the code name Narwhal, Reggie Sorenson was the Red Emperor and Shayna Jack was Starfish. </p> <p>"To get the cast of 'celebrities' into the jungle without revealing the line-up is a covert operation that has been getting more complex every year," the insider said. </p> <p>The source revealed that this is because one of the previous competitors, Sam Dastyari, found  the names of all the celebs before entering the jungle and texted the complete cast list to a journalist in Australia.</p> <p>“We don't even tell Julia Morris and Robert Irwin until we absolutely have to because we literally trust nobody," they continued.</p> <p>“Some people swore black and blue they knew our cast this year but most were way off and that is done on purpose."</p> <p>The insider also revealed the the flights to South Africa were all spread out, with some celebrities flying up to 10 days before they enter the jungle, while others arrived the day before. </p> <p><em>Image: Channel 10</em></p>

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

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

How we diagnose and define obesity is set to change – here’s why, and what it means for treatment

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/louise-baur-5284">Louise Baur</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/john-b-dixon-11630">John B.

Brown</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Obesity is <a href="https://www.niddk.nih.gov/health-information/weight-management/adult-overweight-obesity/health-risks#:%7E:text=Having%20overweight%20or%20obesity%20increases,the%20cells%20in%20your%20body">linked to</a> many common diseases, such as type 2 diabetes, heart disease, fatty liver disease and knee osteoarthritis.</p> <p>Obesity is currently defined using a person’s body mass index, or BMI. This is <a href="https://www.who.int/news-room/fact-sheets/detail/obesity-and-overweight">calculated</a> as weight (in kilograms) divided by the square of height (in metres). In people of European descent, the BMI for obesity is 30 kg/m² and over.</p> <p>But the risk to health and wellbeing is not determined by weight – and therefore BMI – alone. We’ve been part of a global collaboration that has spent the past two years discussing how this should change. Today we publish how we think obesity should be defined and why.</p> <p>As we outline in <a href="https://www.thelancet.com/commissions/clinical-obesity">The Lancet</a>, having a larger body shouldn’t mean you’re diagnosed with “clinical obesity”. Such a diagnosis should depend on the level and location of body fat – and whether there are associated health problems.</p> <h2>What’s wrong with BMI?</h2> <p>The risk of ill health depends on the relative percentage of fat, bone and muscle making up a person’s body weight, as well as where the fat is distributed.</p> <p>Athletes with a relatively high muscle mass, for example, may have a higher BMI. Even when that athlete has a BMI over 30 kg/m², their higher weight is due to excess muscle rather than excess fatty tissue.</p> <p>People who carry their excess fatty tissue <a href="https://www.abc.net.au/news/health/2017-09-06/waist-size-why-it-matters-and-when-its-a-risk/8839708">around their waist</a> are at greatest risk of the health problems associated with obesity.</p> <p>Fat stored deep in the abdomen and around the internal organs can release damaging molecules into the blood. These can then <a href="https://theconversation.com/body-fat-deep-below-the-surface-is-a-toxic-risk-especially-for-your-heart-146307">cause problems</a> in other parts of the body.</p> <p>But BMI alone does not tell us whether a person has health problems related to excess body fat. People with excess body fat don’t always have a BMI over 30, meaning they are not investigated for health problems associated with excess body fat. This might occur in a very tall person or in someone who tends to store body fat in the abdomen but who is of a “healthy” weight.</p> <p>On the other hand, others who aren’t athletes but have excess fat may have a high BMI but no associated health problems.</p> <p>BMI is therefore an imperfect tool to help us diagnose obesity.</p> <h2>What is the new definition?</h2> <p>The goal of the <a href="https://pubmed.ncbi.nlm.nih.gov/36878238">Lancet Diabetes &amp; Endocrinology Commission on the Definition and Diagnosis of Clinical Obesity </a> was to develop an approach to this definition and diagnosis. The commission, established in 2022 and led from King’s College London, has brought together 56 experts on aspects of obesity, including people with lived experience.</p> <p>The commission’s <a href="https://www.thelancet.com/commissions/clinical-obesity">definition and new diagnostic criteria</a> shifts the focus from BMI alone. It incorporates other measurements, such as waist circumference, to confirm an excess or unhealthy distribution of body fat.</p> <p>We define two categories of obesity based on objective signs and symptoms of poor health due to excess body fat.</p> <p><strong>1. Clinical obesity</strong></p> <p>A person with clinical obesity has signs and symptoms of ongoing organ dysfunction and/or difficulty with day-to-day activities of daily living (such as bathing, going to the toilet or dressing).</p> <p>There are 18 diagnostic criteria for clinical obesity in adults and 13 in children and adolescents. These include:</p> <ul> <li> <p>breathlessness caused by the effect of obesity on the lungs</p> </li> <li> <p>obesity-induced heart failure</p> </li> <li> <p>raised blood pressure</p> </li> <li> <p>fatty liver disease</p> </li> <li> <p>abnormalities in bones and joints that limit movement in children.</p> </li> </ul> <p><strong>2. Pre-clinical obesity</strong></p> <p>A person with pre-clinical obesity has high levels of body fat that are not causing any illness.</p> <p>People with pre-clinical obesity do not have any evidence of reduced tissue or organ function due to obesity and can complete day-to-day activities unhindered.</p> <p>However, people with pre-clinical obesity are generally at higher risk of developing diseases such as heart disease, some cancers and type 2 diabetes.</p> <h2>What does this mean for obesity treatment?</h2> <p>Clinical obesity is a disease requiring access to effective health care.</p> <p>For those with clinical obesity, the focus of health care should be on improving the health problems caused by obesity. People should be offered evidence-based treatment options after discussion with their health-care practitioner.</p> <p><a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)01210-8/abstract">Treatment</a> will <a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(22)00047-X/fulltext">include</a> management of obesity-associated complications and may include specific obesity treatment aiming at decreasing fat mass, such as:</p> <ul> <li> <p>support for <a href="https://www.obesityevidencehub.org.au/collections/treatment/behavioural-interventions-for-the-management-of-overweight-and-obesity-in-adults">behaviour change</a> <a href="https://www.obesityevidencehub.org.au/collections/treatment/managing-overweight-and-obesity-in-children-and-adolescents">around</a> diet, physical activity, sleep and screen use</p> </li> <li> <p>obesity-management medications to reduce appetite, lower weight and <a href="https://www.obesityevidencehub.org.au/collections/treatment/medication-and-surgery-for-the-treatment-of-overweight-and-obesity-in-adults">improve health</a> outcomes such as blood glucose (sugar) and blood pressure</p> </li> <li> <p>metabolic <a href="https://theconversation.com/thinking-about-bariatric-surgery-for-weight-loss-heres-what-to-consider-184153">bariatric surgery</a> to treat obesity or reduce weight-related health complications.</p> </li> </ul> <h2>Should pre-clinical obesity be treated?</h2> <p>For those with pre-clinical obesity, health care should be about risk-reduction and prevention of health problems related to obesity.</p> <p>This may require health counselling, including support for health behaviour change, and monitoring over time.</p> <p>Depending on the person’s individual risk – such as a family history of disease, level of body fat and changes over time – they may opt for one of the obesity treatments above.</p> <p>Distinguishing people who don’t have illness from those who already have ongoing illness will enable personalised approaches to obesity prevention, management and treatment with more appropriate and cost-effective allocation of resources.</p> <h2>What happens next?</h2> <p>These new criteria for the diagnosis of clinical obesity will need to be adopted into national and international clinical practice guidelines and a range of obesity strategies.</p> <p>Once adopted, training health professionals and health service managers, and educating the general public, will be vital.</p> <p>Reframing the narrative of obesity may help eradicate misconceptions that contribute to stigma, including making false assumptions about the health status of people in larger bodies. A better understanding of the biology and health effects of obesity should also mean people in larger bodies are not blamed for their condition.</p> <p>People with obesity or who have larger bodies should expect personalised, evidence-based assessments and advice, free of stigma and blame.<!-- Below is The Conversation's page counter tag.

In some of Europe’s most popular holiday destinations, including Barcelona and Mallorca, there were <a href="https://edition.cnn.com/2024/07/27/travel/why-europe-has-become-an-epicenter-for-anti-tourism-protests-this-summer/index.html">large protests</a> against the negative effects of mass tourism.</p> <p>Overcrowding, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0160738319300817?via%3Dihub">environmental damage</a>, <a href="https://www.sciencedirect.com/science/article/pii/S0160738321001420?via%3Dihub">unaffordable housing</a> and cultural erosion appear to have pushed communities to their limits. There are <a href="https://www.bbc.com/travel/article/20240925-the-summer-that-tourism-fell-apart">vocal demands</a> to make tourism <a href="https://www.sciencedirect.com/science/article/pii/S0160738322001621#s0045">more sustainable</a>.</p> <p>So, perhaps it’s time for travellers to <a href="https://www.unwto.org/tourism-data/un-tourism-tourism-dashboard">shift towards</a> a more sensitive and responsible form of travel.</p> <p><a href="https://www.tandfonline.com/doi/full/10.1080/14616688.2022.2044376#abstract">“Regenerative” tourism</a>, for example, aims to enhance the wellbeing of places and the people who live in them. Unlike mass tourism, which often strains resources and compromises residents’ <a href="https://www.tandfonline.com/doi/full/10.1080/21568316.2019.1599604">quality of life</a>, regenerative tourism is about giving back – by supporting local economies, preserving cultures and nurturing the environment.</p> <p>This means treating your holiday as more than a personal escape. Instead of just lying on a sun lounger, consider planting trees in a reforestation project or learning traditional crafts from local artisans and participating in cultural events.</p> <p>Depending on the location, there might be chances to join in <a href="https://www.volunteerworld.com/en/volunteer-abroad/voluntourism">community programmes</a> which help alleviate poverty or improve the lives of Indigenous communities. These actions can empower locals and help create a more inclusive environment.</p> <p>Wherever you go, you can seek out experiences which help to <a href="https://sdgs.un.org/goals">restore and sustain</a> the places you visit. Imagine, for instance, learning traditional Venetian glassblowing techniques as a way of supporting the artisans who keep this ancient craft alive in Italy.</p> <p>In rural Spain, you could support local communities in remote villages by staying in family-run guesthouses. Or in Bulgaria, you could join farm-to-table dining experiences and visit organic farms in the Thracian Valley to help promote local food production and <a href="https://www.un.org/sustainabledevelopment/hunger/">food security</a>.</p> <p>There may be local events or workshops you can join, cooking classes you can take, or cultural festivals where you can interact with residents and appreciate their perspective.</p> <p>All of these – and countless other examples – are opportunities for travellers to make a contribution to the places they visit, leaving a positive impact. They also offer the traveller the chance to make personal connections and unforgettable memories – providing moments to engage directly with locals people, to ask questions and learn about local culture and history and community activities. Being a gracious guest promotes goodwill and strengthens the bond between travellers and locals.</p> <h2>Direction of travel</h2> <p>These connections also make holidays not merely about personal enjoyment, but about something deeper, with a positive affect on the places we visit.</p> <p>So as you browse the idyllic destinations you might decide to travel to in 2025, it’s worth asking yourself whether you want to be a passive tourist, or a regenerative traveller who combines a sense of curiosity with a sense of responsibility.</p> <p>Tourism in 2025 will be a big part of <a href="https://www.sciencedirect.com/science/article/abs/pii/S2211973617300922">many countries’ economies</a>, but not everyone is happy with the industry and its impact on the world. Yet, consumers can change its direction.</p> <p>The choices we make about our travel plans could mean the difference between a holiday that contributes to a legacy of positive change or one that perpetuates the social and environmental issues facing the planet and its people.</p> <p>As we look ahead, the question is not just where to travel on holiday, but how to travel. Perhaps 2025 could be the year that your adventures inspire transformation, creating a sustainable and inclusive future for tourism. It’s a resolution worth thinking about for years to come.<!-- Below is The Conversation's page counter tag.

One way researchers <a href="https://www.sciencedirect.com/science/article/pii/S1369847815001722">measure</a> this is via a testing tool known as the <a href="https://www.yorku.ca/rokada/psyctest/driving.pdf">Driving Anger Scale</a>.</p> <p>Data from many studies using this test show drivers who are more prone to anger in general are <a href="https://research.monash.edu/en/publications/driving-anger-as-a-psychological-construct-twenty-years-of-resear">more likely to turn that anger into aggression</a>. They get annoyed by more things, are quicker to act on their feelings, take more risks, and as a result, are more likely to be involved in anger-related crashes.</p> <p>Research suggests that while female drivers experience anger just as much as male drivers, they are less likely to act on it in a <a href="https://www.turkpsikiyatri.com/PDF/C18S3/en/angerExpression.pdf">negative way</a>.</p> <p>Female drivers tend to feel more intense anger in certain situations, such as when <a href="https://www.sciencedirect.com/science/article/pii/S1369847815001722#f0010">faced with hostile gestures or traffic obstructions</a>, compared to their male counterparts.</p> <h2>What can I do to reduce my road rage?</h2> <p>In a car, we’re physically separated from others, which creates a sense of distance and anonymity – two factors that lower our usual social filters. Encounters feel fleeting.</p> <p>There’s a good chance you won’t be held accountable for what you or say or do, compared to if you were outside the car. And yet, we perceive the stakes as high because mistakes or bad decisions on the road can have serious consequences.</p> <p>This mix of isolation, stress, and the illusion of being in a bubble is a perfect recipe for heightened frustration and anger.</p> <p><a href="https://www.sciencedirect.com/science/article/abs/pii/S0001457521001755?dgcid=raven_sd_recommender_email">Research</a> suggests techniques drawn from cognitive behavioural therapy may help.</p> <p>These include learning to identify when you are starting to feel angry, trying to find alternative explanations for other people’s behaviour, using mindfulness and <a href="https://www.sciencedirect.com/science/article/pii/S1369847815001758">relaxation</a> and trying to move away from the trigger.</p> <p>The American Automobile Association also <a href="https://exchange.aaa.com/wp-content/uploads/2013/06/Road-Rage-Brochure.pdf">suggests</a> you can reduce road rage incidents by being a more considerate driver yourself – always use your indicator, avoid cutting others off and maintain a safe distance from other cars.</p> <p>Try to stay calm when other drivers are angry, and allow extra time in your journey to reduce stress.</p> <p>If driving anger is a frequent issue, consider seeking support or <a href="https://www.healthdirect.gov.au/anger-management">anger management resources</a>.</p> <p>Avoiding — or at least being aware of — <a href="https://www.sciencedirect.com/science/article/pii/S1369847821002667">anger rumination</a> can make a big difference. This happens when someone replays anger-inducing events, like being cut off in traffic, over and over in their mind. Instead of letting it go, they dwell on it, fuelling their frustration and making it harder to stay calm.</p> <p>Recognising this pattern and shifting focus — like taking a deep breath or distracting yourself — can help stop anger from escalating into aggression.</p> <p>More broadly, public awareness campaigns highlighting the link between anger and risky driving could also encourage more drivers to seek help.</p> <p>The next time you get behind the wheel, try to remember the other driver, the cyclist, or pedestrian is just another person — someone you might pass on the street without a second thought.</p> <p>We’re often good at forgiving minor missteps in non-driving contexts.

Most adults will gain half a kilo this year – and every year. Here’s how to stop ‘weight creep’

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>As we enter a new year armed with resolutions to improve our lives, there’s a good chance we’ll also be carrying something less helpful: extra kilos. At least half a kilogram, to be precise.</p> <p>“Weight creep” doesn’t have to be inevitable. Here’s what’s behind this sneaky annual occurrence and some practical steps to prevent it.</p> <h2>Small gains add up</h2> <p>Adults <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3151731/">tend to gain weight</a> progressively as they age and typically gain an average of <a href="https://pubmed.ncbi.nlm.nih.gov/23638485/">0.5 to 1kg every year</a>.</p> <p>While this doesn’t seem like much each year, it amounts to 5kg over a decade. The slow-but-steady nature of weight creep is why many of us won’t notice the extra weight gained until we’re in our fifties.</p> <h2>Why do we gain weight?</h2> <p>Subtle, gradual lifestyle shifts as we progress through life and age-related biological changes cause us to gain weight. Our:</p> <ul> <li> <p>activity levels decline. Longer work hours and family commitments can see us become more sedentary and have less time for exercise, which means we burn fewer calories</p> </li> <li> <p>diets worsen. With frenetic work and family schedules, we sometimes turn to pre-packaged and fast foods. These processed and discretionary foods are loaded with hidden sugars, salts and unhealthy fats. A better financial position later in life can also <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1467-789X.2011.00953.x">result in more dining out</a>, which is associated with a higher total energy intake</p> </li> <li> <p>sleep decreases. Busy lives and screen use can mean we don’t get enough sleep. This disturbs our body’s energy balance, increasing our <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945708700133">feelings of hunger</a>, triggering cravings and decreasing our energy</p> </li> </ul> <ul> <li> <p>stress increases. Financial, relationship and work-related stress increases our body’s production of cortisol, triggering food cravings and promoting fat storage</p> </li> <li> <p>metabolism slows. Around the age of 40, our muscle mass naturally declines, and our body fat starts increasing. Muscle mass helps determine our metabolic rate, so when our muscle mass decreases, our bodies start to burn fewer calories at rest.</p> </li> </ul> <p>We also <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2807660">tend to gain a small amount</a> of weight during festive periods – times filled with calorie-rich foods and drinks, when exercise and sleep are often overlooked. <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2807660">One study of Australian adults</a> found participants gained 0.5 kilograms on average over the Christmas/New Year period and an average of 0.25 kilograms around Easter.</p> <h2>Why we need to prevent weight creep</h2> <p>It’s important to prevent weight creep for two key reasons:</p> <p><strong>1. Weight creep resets our body’s set point</strong></p> <p>Set-point theory suggests we each have a predetermined weight or set point. Our body works to <a href="https://theconversation.com/whats-the-weight-set-point-and-why-does-it-make-it-so-hard-to-keep-weight-off-195724">keep our weight around this set point</a>, adjusting our biological systems to regulate how much we eat, how we store fat and expend energy.</p> <p>When we gain weight, our set point resets to the new, higher weight. Our body adapts to protect this new weight, making it challenging to lose the weight we’ve gained.</p> <p>But it’s also possible to <a href="https://theconversation.com/whats-the-weight-set-point-and-why-does-it-make-it-so-hard-to-keep-weight-off-195724">lower your set point</a> if you lose weight gradually and with an interval weight loss approach. Specifically, losing weight in small manageable chunks you can sustain – periods of weight loss, followed by periods of weight maintenance, and so on, until you achieve your goal weight.</p> <p><strong>2. Weight creep can lead to obesity and health issues</strong></p> <p>Undetected and unmanaged weight creep <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5817436/">can result in</a> obesity which can increase our risk of heart disease, strokes, type 2 diabetes, osteoporosis and several types of cancers (including breast, colorectal, oesophageal, kidney, gallbladder, uterine, pancreatic and liver).</p> <p>A <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5817436/">large study</a> examined the link between weight gain from early to middle adulthood and health outcomes later in life, following people for around 15 years. It found those who gained 2.5 to 10kg over this period had an increased incidence of type 2 diabetes, heart disease, strokes, obesity-related cancer and death compared to participants who had maintained a stable weight.</p> <p>Fortunately, there are steps we can take to build lasting habits that will make weight creep a thing of the past.</p> <h2>7 practical steps to prevent weight creep</h2> <p><strong>1. Eat from big to small</strong></p> <p>Aim to consume most of your food earlier in the day and taper your meal sizes to ensure dinner is the smallest meal you eat.</p> <p>A low-calorie or small breakfast <a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">leads to increased feelings of hunger</a>, specifically appetite for sweets, across the course of the day.</p> <p>We burn the calories from a meal <a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">2.5 times more efficiently</a> in the morning than in the evening. So emphasising breakfast over dinner is also good for weight management.</p> <p><strong>2. Use chopsticks, a teaspoon or an oyster fork</strong></p> <p>Sit at the table for dinner and use different utensils to encourage eating more slowly.</p> <p>This gives your brain time to recognise and adapt to signals from your stomach <a href="https://pubmed.ncbi.nlm.nih.gov/28718396/">telling you you’re full</a>.</p> <p><strong>3. Eat the full rainbow</strong></p> <p>Fill your plate with vegetables and fruits of different colours first to support eating a high-fibre, nutrient-dense diet that will keep you feeling full and satisfied.</p> <p>Meals also need to be balanced and include a source of protein, wholegrain carbohydrates and healthy fat to meet our dietary needs – for example, eggs on wholegrain toast with avocado.</p> <p><strong>4. Reach for nature first</strong></p> <p>Retrain your brain to rely on nature’s treats – fresh vegetables, fruit, honey, nuts and seeds. In their natural state, these foods release the same pleasure response in the brain as ultra-processed and fast foods, helping you avoid unnecessary calories, sugar, salt and unhealthy fats.</p> <p><strong>5. Choose to move</strong></p> <p>Look for ways to incorporate incidental activity into your daily routine – such as taking the stairs instead of the lift – and <a href="https://theconversation.com/does-exercise-help-you-lose-weight-198292">boost your exercise</a> by challenging yourself to try a new activity.</p> <p>Just be sure to include variety, as doing the same activities every day often results in boredom and avoidance.</p> <p><strong>6. Prioritise sleep</strong></p> <p>Set yourself a goal of getting a minimum of <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945708700133">seven hours of uninterrupted sleep</a> each night, and help yourself achieve it by <a href="https://www.nature.com/articles/ncomms3259">avoiding screens</a> for an hour or <a href="https://journals.sagepub.com/doi/abs/10.1177/1477153515584979?journalCode=lrtd">two</a> before bed.</p> <p><strong>7. Weigh yourself regularly</strong></p> <p>Getting into the habit of weighing yourself weekly is a guaranteed way <a href="https://theconversation.com/how-often-should-you-really-weigh-yourself-223864">to help avoid the kilos creeping up</a> on us. Aim to weigh yourself on the same day, at the same time and in the same environment each week and use the best quality scales you can afford.</p> <hr /> <p><em>At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss. <a href="https://redcap.sydney.edu.au/surveys/?s=RKTXPPPHKY">You can register here</a> to express your interest.</em><!-- Below is The Conversation's page counter tag.

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

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

Going for a bushwalk? 3 handy foods to have in your backpack (including muesli bars)

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/margaret-murray-1173544">Margaret Murray</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>This time of year, many of us love to get out and spend time in nature. This may include hiking through Australia’s many beautiful <a href="https://www.nationalparks.nsw.gov.au/conservation-and-heritage/national-parks/australias-national-parks">national parks</a>.</p> <p>Walking in nature is a wonderful activity, supporting both <a href="https://doi.org/10.1108/S2044-994120170000009004">physical</a> and <a href="https://link.springer.com/article/10.1007/s12144-023-05112-z">mental health</a>. But there can be risks and it’s important to be prepared.</p> <p>You may have read the news about hiker, Hadi Nazari, who was <a href="https://www.theguardian.com/australia-news/2025/jan/08/how-missing-hiker-survived-in-kosciuszko-national-park">recently found</a> alive after spending 13 days lost in Kosciuszko National Park.</p> <p>He reportedly survived for almost two weeks in the Snowy Mountains region of New South Wales by drinking fresh water from creeks, and eating foraged berries and two muesli bars.</p> <p>So next time you’re heading out for a day of hiking, what foods should you pack?</p> <p>Here are my three top foods to carry on a bushwalk that are dense in nutrients and energy, lightweight and available from the local grocery store.</p> <h2>1. Muesli bars</h2> <p>Nazari <a href="https://www.theguardian.com/australia-news/2025/jan/09/hiker-who-left-museli-bars-in-kosciuszko-hut-hadi-nazari">reportedly ate</a> two muesli bars he found in a mountain hut. Whoever left the muesli bars there made a great choice.</p> <p>Muesli bars come individually wrapped, which helps them last longer and makes them easy to transport.</p> <p>They are also a good source of energy. Muesli bars typically contain about <a href="https://afcd.foodstandards.gov.au/fooddetails.aspx?PFKID=F000333">1,500</a>-<a href="https://afcd.foodstandards.gov.au/fooddetails.aspx?PFKID=F000344">1,900</a> kilojoules per 100 grams. The average energy content for a 35g bar is <a href="https://doi.org/10.3390/foods8090370">about 614kJ</a>.</p> <p>This may be <a href="https://www.eatforhealth.gov.au/nutrient-reference-values/nutrients/dietary-energy">a fraction</a> of what you’d usually need in a day. However, the energy from muesli bars is released at a <a href="https://glycemicindex.com/gi-search/?food_name=muesli+bar&amp;product_category=&amp;country=&amp;gi=&amp;gi_filter=&amp;serving_size_(g)=&amp;serving_size_(g)_filter=&amp;carbs_per_serve_(g)=&amp;carbs_per_serve_(g)_filter=&amp;gl=&amp;gl_filter=">slow to moderate pace</a>, which will help keep you going for longer.</p> <p>Muesli bars are also <a href="https://afcd.foodstandards.gov.au/fooddetails.aspx?PFKID=F000333">packed with nutrients</a>. They contain all three macronutrients (carbohydrate, protein and fat) that our body needs to function. They’re a good source of carbohydrates, in particular, which are a key energy source. An average Australian muesli bar contains <a href="https://doi.org/10.3390/foods8090370">14g of whole grains</a>, which provide carbohydrates and dietary fibre for long-lasting energy.</p> <p>Muesli bars that contain nuts <a href="https://afcd.foodstandards.gov.au/fooddetails.aspx?PFKID=F000344">are typically</a> higher in fat (19.9g per 100g) and protein (9.4g per 100g) than <a href="https://afcd.foodstandards.gov.au/fooddetails.aspx?PFKID=F000333">those without</a>.</p> <p>Fat and protein are helpful for <a href="https://pubmed.ncbi.nlm.nih.gov/16988118/">slowing down</a> the release of energy from foods and the protein will help keep you <a href="https://doi.org/10.1016/j.foodhyd.2016.08.003">feeling full for longer</a>.</p> <p>There are many different types of muesli bars to choose from. I recommend looking for those with whole grains, higher dietary fibre and higher protein content.</p> <h2>2. Nuts</h2> <p>Nuts are nature’s savoury snack and are also a great source of energy. Cashews, pistachios and peanuts contain about <a href="https://www.researchgate.net/publication/6671761_Nuts_Source_of_energy_and_macronutrients#fullTextFileContent">2,300-2,400kJ per 100g</a> while Brazil nuts, pecans and macadamias contain about <a href="https://www.researchgate.net/publication/6671761_Nuts_Source_of_energy_and_macronutrients#fullTextFileContent">2,700-3,000kJ per 100g</a>. So a 30g serving of nuts will provide about 700-900kJ depending on the type of nut.</p> <p>Just like muesli bars, the energy from nuts <a href="https://glycemicindex.com/gi-search/?food_name=nut+&amp;product_category=nuts&amp;country=&amp;gi=&amp;gi_filter=&amp;serving_size_(g)=&amp;serving_size_(g)_filter=&amp;carbs_per_serve_(g)=&amp;carbs_per_serve_(g)_filter=&amp;gl=&amp;gl_filter=">is released slowly</a>. So even a relatively small quantity will keep you powering on.</p> <p>Nuts are also <a href="https://www.mdpi.com/2304-8158/12/5/942">full of nutrients</a>, such as protein, fat and fibre, which will help to <a href="https://doi.org/10.1080/10408398.2018.1514486">stave off hunger</a> and keep you moving for longer.</p> <p>When choosing which nuts to pack, almost any type of nut is going to be great.</p> <p>Peanuts are often the best value for money, or go for something like walnuts that are <a href="https://afcd.foodstandards.gov.au/fooddetails.aspx?PFKID=F006116">high in omega-3 fatty acids</a>, or a nut mix.</p> <p>Whichever nut you choose, go for the unsalted natural or roasted varieties. Salted nuts will make you thirsty.</p> <p>Nut bars are also a great option and have the added benefit of coming in pre-packed serves (although nuts can also be easily packed into re-usable containers).</p> <p>If you’re allergic to nuts, roasted chickpeas are another option. Just try to avoid those with added salt.</p> <h2>3. Dried fruit</h2> <p>If nuts are nature’s savoury snack, fruit is nature’s candy. Fresh fruits (such as grapes, frozen in advance) are wonderfully refreshing and perfect as an everyday snack, although can add a bit of weight to your hiking pack.</p> <p>So if you’re looking to reduce the weight you’re carrying, go for dried fruit. It’s lighter and will withstand various conditions better than fresh fruit, so is less likely to spoil or bruise on the journey.</p> <p>There are lots of varieties of dried fruits, such as sultanas, dried mango, dried apricots and dried apple slices.</p> <p>These are good sources of <a href="https://afcd.foodstandards.gov.au/fooddetails.aspx?PFKID=F008983">sugar for energy</a>, <a href="https://doi.org/10.3390/nu10121833">fibre</a> for fullness and healthy digestion, and contain <a href="http://dx.doi.org/10.12944/CRNFSJ.10.1.06">lots of vitamins and minerals</a>. So choose one (or a combination) that works for you.</p> <h2>Don’t forget water</h2> <p>Next time you head out hiking for the day, you’re all set with these easily available, lightweight, energy- and nutrient-dense snacks.</p> <p>This is not the time to be overly concerned about limiting your sugar or fat intake. Hiking, particularly in rough terrain, places demands on your body and energy needs. For instance, an adult hiking in rough terrain can burn upwards <a href="https://scholar.ufs.ac.za/server/api/core/bitstreams/eb9b5b76-bdfc-456f-b833-c3e285948e4a/content">of about</a> 2,000kJ per hour.</p> <p>And of course, don’t forget to take plenty of water.</p> <p>Having access to even limited food, and plenty of fresh water, will not only make your hike more pleasurable, it can save your life.<!-- Below is The Conversation's page counter tag.

Do natural fabrics really keep us cooler in summer? Here’s the science

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nisa-salim-1442233">Nisa Salim</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>The Bureau of Meteorology has warned Australia is facing one of the <a href="https://www.abc.net.au/news/2024-10-12/australia-facing-one-of-hottest-summers-on-record-bom/104464014">hottest summers on record</a>. As the weather warms, many of us reach for light-coloured clothes in natural fabrics, such as cotton and linen.</p> <p>But why are natural fabrics like these so much better at keeping us cool when the weather is hot?</p> <p>Here’s what the science says.</p> <h2>Natural fabrics and sweat: a match made in heaven</h2> <p>In hot weather, we sweat. As sweat evaporates, it carries heat away, which helps cool the body down.</p> <p>In hot weather, then, we want clothes that help take moisture away from the body as efficiently as possible.</p> <p>Natural fabrics are made using fibres extracted from plant- or animal-based sources such as cotton, linen, hemp, wool and silk.</p> <p>The primary component of all plant-based fibres is cellulose. Animal-based fibres are made up of proteins such as keratin and silk fibroin.</p> <p>Cellulose molecules are rich in compounds called hydroxyl groups that attract water and moisture. In scientific terms, they are hydrophilic – they love water.</p> <p>So, clothing made of cotton and linen is highly hydrophilic. It tends to absorb moisture and disperse it across the fabric, allowing it to evaporate more easily.</p> <p>This takes the sweat away quickly, making it more comfortable and breathable and allowing us to stay cool in sweltering temperatures.</p> <p>One downside of the natural fabrics is they wrinkle quickly (some people, of course, like that look).</p> <p>And on a really hot, sweaty day, natural fabrics can get heavy and wet.</p> <p>Animal fibres are basically proteins, and their properties vary depending on the source.</p> <p>Wool has been bio-engineered over millions of years to be comfortable to wear. Wool fibres are hydrophilic on the inside and hydrophobic on the outside, meaning they’re both water resistant and good at wicking moisture away.</p> <p>On the other hand, silk fabrics are very good at helping regulate temperature; they keep us cool in hot weather and warm in cold weather.</p> <h2>Synthetic fabrics: less wrinkly, more sweaty</h2> <p>Synthetic fabrics, on the other hand, are lighter and tend to wrinkle less.</p> <p>Common synthetic fabrics (such as polyester, nylon and acrylic) are all made from petroleum-based chemicals.</p> <p>Most synthetic fibres are made of long chains of hydrogen and carbon atoms and do not contain the hydroxyl groups we discussed earlier.</p> <p>Such fibres are therefore hydrophobic – they hate water. This means the water can’t spread evenly across the fabric and evaporate easily.</p> <p>They trap sweat against the skin, making the clothes less breathable and comfortable when the weather is warm and humid.</p> <p>However, some synthetic fabrics used in certain types of active wear can wick sweat away from body.</p> <p>And some semi-synthetic fabrics such as rayon or tencel (which are made from wood pulp or cotton with synthetic fibres) are more breathable than other synthetic fabrics such as polyester or nylon.</p> <h2>Fabric weave makes a difference, too</h2> <p>The colour of the clothing is also a contributing factor to keep you cool during summer. Light colours reflect sunlight away from you and help to keep the body cooler.</p> <p>There is some evidence dark colours absorb the <a href="https://www.sciencedirect.com/science/article/pii/S2214157X23012054">sunlight and associated heat</a>, making the surface of the skin warmer than normal.</p> <p>Another factor affecting breathability and comfort of clothing is the way the fabrics are woven.</p> <p>Fabrics that are loosely woven (sometimes known as “open weave”) with thinner materials naturally have more airflow, which helps you keep cool.</p> <p>For a quick, non-scientific test, hold a fabric up and see how much light passes through it. The more light you can see, the more breathable it likely is.</p> <p>The way the fabric is treated can play a role, too; such as for softening and wrinkle resistance.</p> <p>Using a fabric softener when you do a load of laundry usually doesn’t affect fabric breathability; softeners modify the surface of the fabric but don’t change the internal structure or porous nature of the fabrics.</p> <p>Wrinkle resistance is the ability of the fabric to stay smooth and polished even after washing. Synthetic fabrics are inherently wrinkle resistant. Natural fibres are more prone to wrinkles but can be chemically treated on the fabric surface during manufacturing to make them wrinkle resistant.</p> <p>Such treatments, however, may form layers on top of the fabric blocking the airflow, leading them to be less breathable.<!-- Below is The Conversation's page counter tag.

<p>Former NSW premier Mike Baird has reflected on the Lindt cafe siege that left two hostages dead in December 2014, revealing his struggle with post-traumatic stress. </p> <p>Baird, who was the state premier at the time of the attack, said it was his mother - who is a psychologist - who first noticed his signs of PTSD after he was tasked with coordinating a response to the siege. </p> <p>"I ignored it and there was other things to get on with and be busy about. But I should have listened," Baird told <em><a href="https://9now.nine.com.au/60-minutes/mike-baird-former-nsw-premier-mental-health-struggle-10-years-after-lindt-cafe-siege/e5376455-411a-4b25-b71d-526eb86f7995" target="_blank" rel="noopener">60 Minutes</a></em>. </p> <p>Reflecting on the terrifying day, he said, "Everyone just wanted them out. And you know, for it not to happen, there's a deep grief in that. And I think the impact is felt by everyone."</p> <p>"To have that loss of Tori and Katrina, I'll never lose that," Baird said, referring to the two hostages who were tragically killed during the siege.</p> <p>"It's just impossible not to feel guilt."</p> <p>Baird admitted he struggled to validate his own mental struggles, saying it feels like a very small part of the impact the siege had on Australians, including the enormous pain felt by the families of cafe manager Tori Johnson and barrister Katrina Dawson who lost their lives. </p> <p>"In my mind there's a sense of, 'I shouldn't be impacted that way'," Baird said. "I was just there as an observer and trying to coordinate a response." </p> <p>Several hostages who survived the terrifying ordeal, including Louisa Hope, told 60 Minutes that the memories will never leave them.</p> <p>"For me personally it does not go away, but it is the thing that pushes me to continue to find the good or to find a good out of that awful situation," she said.</p> <p><em>Image credits: 60 Minutes</em></p>
