Readers response: Is there any item of memorabilia you’ve passed down to family or plan to in the future?

As in many families, there are often sentimental items and memorabilia that are passed down from several generations. We asked our readers if there are any heirlooms that they have passed down to their younger family members, or if they plan to, and the response was overwhelming. Here's what they said. Marjorie Gale - The christening gown made by my Aunt in the UK in 1955 for my eldest daughter, worn by my two other daughters. Now been worn by my 9 grandchildren and 12 great grandchildren, and another due soon. So far 24 babies have worn it. Dawn Douglas - Yes, I have my Mums jewellery box and my eldest daughter will get it when I’m gone. I also have a brooch that belonged to my Nana. Sue Crawley - I have a 1925 gold embossed book by AA Milne “When We Were Very Young”. My most cherished memory was sitting on my great grandfathers knee whilst he read it to me. Not sure yet which grandchild will receive it. Greg Browning - A Winchester rifle my great grandfather bought in the 1800s. Have already passed it on. Marion Ingram - Family bassinets. Now on its 4th generation! Margie Buckingham - My grandmother’s costume jewellery was stunning. She was a racehorse breeder always in the Flemington Racecourse members, even had many Group One winners, so her jewellery had to look special. Paul Uttley - A silver pocket knife that belonged to my great grandfather now belongs to my oldest grandson (six generations apart)! Image credits: Shutterstock

How do I know when it’s time to replace my running shoes?

<a href="https://theconversation.com/profiles/john-arnold-178470">John Arnold</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/joel-fuller-2210202">Joel Fuller</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> Any runner will tell you there’s nothing better than slipping on a brand new pair of shoes. But how regularly should runners fork out hundreds of dollars on their next pair? Conventional wisdom tells us the average lifespan of a running shoe is around 500 to 800 kilometres. But where did this advice come from, and is it based on science? Some evidence comes from <a href="https://doi.org/10.1177/0363546585013004">impact testing</a> with machines designed to simulate the shoe repeatedly contacting the ground during running. Other evidence comes from <a href="https://doi.org/10.1080/19424280.2010.519348">monitoring runners who have used shoes in the real world</a> for long periods. This research is often focused on shoe materials and structure. But we think more compelling markers for the runner are shoe comfort, performance benefit and injury risk. Rather than seeking a “one-size-fits-all” answer to how many kilometres your shoes should be limited to, it’s also better to consider individual signs based on your shoe type and its purpose. <h2>The three signs to watch for</h2> Runners tend to replace their shoes for three main reasons: <ol> <li>they believe their performance is being negatively impacted</li> <li>their shoes are leading to some bodily discomfort which may cause (or has already caused) an injury</li> <li>the shoes are no longer comfortable or “feel” as good as they used to.</li> </ol> So what does the evidence say about these factors? <h2>Performance</h2> Some shoe material properties do contribute to enhanced running efficiency. Degrading these materials by racking up the kilometres may hinder peak performance on race day. This is most clearly seen in carbon fibre plate shoes used by modern elite runners to achieve <a href="https://doi.org/10.1007/s40279-020-01420-7">rapid road race times</a>. The design features <a href="https://doi.org/10.1007/s40279-018-1024-z">thought to drive this</a> are the combination of highly compliant and resilient midsole foam and a stiff embedded carbon fibre plate, which support energy storage and return. Runners will typically “save” these shoes for race day and replace them after fewer kilometres, compared to conventional running shoes. The available research does support the <a href="https://doi.org/10.1007/s40279-017-0811-2">performance benefits of these shoes</a>. However, it’s not known how long the benefits last relative to kilometres of wear. To our best knowledge, there’s only one study on running performance and shoe wear, but unfortunately it did not involve carbon fibre plate shoes. A University of Connecticut 2020 <a href="http://hdl.handle.net/11134/20002:860659513">master’s thesis</a> investigated eight college-level runners over 400 miles (643km) of Nike Pegasus shoe use. Large reductions in running economy were reported at 240km, and this was statistically significant at 320km. No reduction was observed at 160km. So, if you’re chasing personal best times, the evidence above suggests that for peak performance, shoes should be replaced somewhere between 160 and 240km (although this is not directly based on carbon fibre plate shoe research). It appears that minimising training kilometres for your favourite racing shoes – keeping them “fresh” – could contribute to peak performance on race day, compared to racing in a pair of old shoes. <h2>Injury or discomfort</h2> The link between shoe wear and injury is unclear, and based on <a href="https://bjsm.bmj.com/content/37/3/239">minimal and often conflicting evidence</a>. One study did find that <a href="https://doi.org/10.1111/sms.12154">runners who alternate their running shoes</a> have a lower risk of injury than runners who run only in the same pair of shoes over a 22-week period. Runners who alternated shoes throughout the study period would have accumulated less wear in each shoe. This provides some support for the notion that accumulating too many kilometres in your shoes may increase risk of injury. Unfortunately, the exact age of running shoes was not reported in this study. However, based on the running characteristics reported, the single-shoe pair users completed an average of 320km in their shoes (after adjusting for a small fraction who had to replace shoes during the study). This was compared to the multi-shoe pair users who used an average of 3.6 pairs of shoes, ran more total kilometres, but accumulated an average of only 200km per shoe pair. <h2>Comfort</h2> Comfort and fit are the <a href="https://www.tandfonline.com/doi/full/10.1080/19424280.2024.2353597#abstract">two most important factors</a> to runners when selecting running shoes. Evidence linking improved shoe comfort to <a href="https://journals.lww.com/acsm-msse/fulltext/2001/11000/relationship_between_footwear_comfort_of_shoe.21.aspx">reduced injury rates</a> or <a href="https://www.tandfonline.com/doi/full/10.1080/17461391.2019.1640288">improved running economy</a> is mixed, but reducing harms from poorly fitting and uncomfortable shoes is clearly a priority for runners. Most <a href="https://commons.nmu.edu/isbs/vol35/iss1/293/">runners land on their heel</a>. The repeated compression of the midsole causes the material to harden, possibly after as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5534152/pdf/ijspt-12-616.pdf">little as 160km</a>, according to one study from 2017. However, there was virtually no change in the amount of cushioning runners perceived under their heel after 160km. Even after using the shoes for 640km, they felt little difference – about 3%. While at first this might seem like runners are not very good at judging when shoes lose their cushioning, it also tells us changes in perceived shoe cushioning are very gradual and may not be important for runners until they reach a certain threshold. This amount will differ from person to person, and from shoe to shoe, but research suggests it’s not until perceived cushioning reaches about a <a href="https://www.tandfonline.com/doi/full/10.1080/02640414.2020.1773613?casa_token=P87vatZhOlgAAAAA%3ACu11TZmGjKc1xYsaUlEVfWvZDvcSnx3qgKL1E2DsRYwf6hMvBiyVAm-M_-4Iauq4lwHna0QMu1IRmw">10% change</a> that runners consider it meaningful. We must be careful when applying these findings to the latest running shoes which use newer materials. But you can use it as a rule of thumb – once you notice a drop in comfort, it’s time to get a new pair. <h2>When to choose new shoes</h2> Ultimately, there’s no one simple answer for when you should get new running shoes. You may also not keep close track of how many kilometres your favourite pair has racked up. Overall, we believe the most practical advice is to keep your racing shoes “fresh” (under 240km), alternate a couple of other pairs during regular training, and replace them when you detect a notable drop in comfort.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/238997/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/john-arnold-178470">John Arnold</a>, Senior lecturer, Sport & Exercise Biomechanics, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/joel-fuller-2210202">Joel Fuller</a>, Senior Lecturer, Department of Health Sciences, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

New research proves travelling can slow down the ageing process

It turns out that going on holiday is good for you in more ways than one. According to new research conducted at Edith Cowan University in Western Australia, travelling can actually slow the ageing process both physically and mentally. The study, published in the <a title="Journal of Travel Research" href="https://journals.sagepub.com/doi/10.1177/00472875241269892#:~:text=The%20principle%20of%20entropy%20increase%20provides%20a%20dynamic%20perspective%20to,Silva%20%26%20Annamalai%2C%202008)." target="_blank" rel="noopener">Journal of Travel Research</a>, is believed to be the first-ever that applied the theory of entropy - the general trend of the universe towards death and disorder – to tourism. "Tourism isn't just about leisure and recreation. It could also contribute to people's physical and mental health," ECU PhD candidate Fangli Hu said. "Ageing, as a process, is irreversible. While it can't be stopped, it can be slowed down." According to the research, travelling, exploring new corners of the world and engaging in unique and relaxing activities can stimulate stress responses and elevate metabolic rates, positively influencing metabolic activities and the body's self-organising capabilities. "Leisurely travel activities might help alleviate chronic stress, dampen over-activation of the immune system, and encourage normal functioning of the self-defence system," Fangli added. While some people prefer relaxing holidays, others prefer to stay on their feet and keep active during their travels, enjoying the many well-known benefits of exercise. It can "enhance the body's immune function and self-defence capabilities, bolstering its hardiness to external risks". In response to their study, the experts suggested that "travel therapy could serve as a groundbreaking health intervention." Despite the positive results of the research, experts also warned that travelling can exposed to infectious diseases, accidents, injuries, violence, water and food safety issues, and concerns related to inappropriate tourism engagement, which in turn will have the opposite effect on our health. "Conversely, tourism can involve negative experiences that potentially lead to health problems, paralleling the process of promoting entropy increase," Fangli said. Image credits: Shutterstock

I’m feeling run down. Why am I more likely to get sick? And how can I boost my immune system?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/sathana-dushyanthen-1169328">Sathana Dushyanthen</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> It has been a long winter, filled with many viruses and cost-of-living pressures, on top of the usual mix of work, study, life admin and caring responsibilities. Stress is an inevitable part of life. In short bursts, our stress response has evolved as a survival mechanism to help us be more alert in <a href="https://theconversation.com/no-you-cant-blame-all-your-health-issues-on-high-cortisol-heres-how-the-hormone-works-203162">fight or flight situations</a>. But when stress is chronic, it weakens the immune system and makes us more vulnerable to illnesses such as the <a href="https://www.healthline.com/health/can-stress-make-you-sick#:%7E:text=The%20common%20cold&text=Inflammation%20has%20been%20linked%20to,to%20the%20cold%2Dcausing%20germs.">common cold</a>, <a href="https://journals.lww.com/psychosomaticmedicine/abstract/1999/03000/psychological_stress,_cytokine_production,_and.9.aspx">flu</a> and <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/smi.3017">COVID</a>. <h2>Stress makes it harder to fight off viruses</h2> When the immune system starts to break down, a virus that would normally have been under control starts to flourish. Once you begin to feel sick, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4465119/">stress response</a> rises, making it harder for the immune system to fight off the disease. You may be sick more often and for longer periods of time, without enough immune cells primed and ready to <a href="https://link.springer.com/chapter/10.1007/978-3-030-16996-1_6">fight</a>. In the 1990s, American psychology professor Sheldon Cohen and his colleagues conducted a number of <a href="https://www.cmu.edu/common-cold-project/">studies</a> where healthy people were exposed to an upper respiratory infection, through drops of virus placed directly into their <a href="https://www.nejm.org/doi/full/10.1056/NEJM199108293250903">nose</a>. These participants were then quarantined in a hotel and monitored closely to determine who became <a href="https://theconversation.com/stress-less-it-might-protect-you-from-covid-153361">ill</a>.

In the short term, cortisol suppresses inflammation, to ensure the body has enough energy available to respond to an <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2019.00245/full">immediate threat</a>. But in the longer term, chronic stress can be harmful. A Harvard University study <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2796097">from 2022</a> showed that people suffering from psychological distress in the lead up to their COVID infection had a greater chance of experiencing long COVID. They <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2796097">classified</a> this distress as depression, probable anxiety, perceived stress, worry about COVID and loneliness. Those suffering distress had close to a <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2796097">50% greater risk</a> of long COVID compared to other <a href="https://theconversation.com/being-stressed-out-before-you-get-covid-increases-your-chances-of-long-covid-heres-why-190649">participants</a>. Cortisol has been shown to be high in the most severe cases of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7102614/">COVID</a>. <h2>Stress causes inflammation</h2> <a href="https://stories.uq.edu.au/imb/the-edge/inflammation/what-is-inflammation/index.html">Inflammation</a> is a short-term reaction to an injury or infection. It is responsible for trafficking immune cells in your body so the right cells are present in the right locations at the right times and at the right <a href="https://link.springer.com/article/10.1007/s12026-014-8517-0">levels</a>. The immune cells also store a memory of that threat to respond faster and more effectively the next <a href="https://theconversation.com/being-stressed-out-before-you-get-covid-increases-your-chances-of-long-covid-heres-why-190649">time</a>. Initially, circulating immune cells detect and flock to the site of <a href="https://www.nature.com/articles/ni1275">infection</a>. Messenger proteins, known as pro-inflammatory cytokines, are released by immune cells, to signal the danger and recruit help, and our immune system responds to neutralise the <a href="https://stories.uq.edu.au/imb/the-edge/inflammation/what-is-inflammation/index.html">threat</a>. During this response to the infection, if the immune system produces too much of these inflammatory chemicals, it can trigger symptoms such as nasal congestion and runny <a href="https://journals.sagepub.com/doi/full/10.1177/1745691620942516">nose</a>. <h2>What about chronic stress?</h2> Chronic stress causes persistently high cortisol secretion, which remains high even in the absence of an immediate <a href="https://theconversation.com/no-you-cant-blame-all-your-health-issues-on-high-cortisol-heres-how-the-hormone-works-203162">stressor</a>. The immune system becomes desensitised and unresponsive to this <a href="https://www.sciencedirect.com/science/article/abs/pii/S1043661816307435">cortisol suppression</a>, increasing low-grade “silent” inflammation and the production of pro-inflammatory cytokines (the messenger proteins). Immune cells become exhausted and start to <a href="https://www.fxmedicine.com.au/blog-post/adrenal-immune-connection">malfunction</a>. The body loses the ability to turn down the inflammatory <a href="https://journals.sagepub.com/doi/full/10.1177/1745691620942516">response</a>. Over time, the immune system changes the way it responds by reprogramming to a “<a href="https://www.unimelb.edu.au/newsroom/news/2021/april/how-stress-can-stop-immune-cells-in-their-tracks">low surveillance mode</a>”. The immune system misses early opportunities to destroy threats, and the process of recovery can take <a href="https://theconversation.com/being-stressed-out-before-you-get-covid-increases-your-chances-of-long-covid-heres-why-190649">longer</a>. <h2>So how can you manage your stress?</h2> We can actively strengthen our immunity and natural defences by managing our <a href="https://theconversation.com/stuck-in-fight-or-flight-mode-5-ways-to-complete-the-stress-cycle-and-avoid-burnout-or-depression-218599">stress levels</a>. Rather than letting stress build up, try to address it early and frequently by: 1) Getting enough sleep Getting enough sleep reduces <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3132857/">cortisol levels</a> and inflammation. During sleep, the immune system <a href="https://link.springer.com/chapter/10.1007/978-1-4939-6578-6_12">releases</a> <a href="https://theconversation.com/sleep-wont-cure-the-coronavirus-but-it-can-help-our-bodies-fight-it-134674">cytokines</a>, which help fight infections and inflammation. 2) Taking regular exercise Exercising helps the lymphatic system (which balances bodily fluids as part of the immune system) circulate and allows immune cells to monitor for threats, while sweating flushes <a href="https://www.healthline.com/nutrition/does-exercise-boost-immune-system">toxins</a>. Physical activity also lowers stress hormone levels through the release of positive brain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7387807/">signals</a>. 3) Eating a healthy diet Ensuring your diet contains enough nutrients – such as the B vitamins, and the full breadth of minerals like magnesium, iron and zinc – during times of stress has a positive impact on overall stress <a href="https://www.ncbi.nlm.nih.gov/pubmed/22782571">levels</a>.

4 ways to cut down on meat when dining out – and still make healthy choices

.<a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Many of us are looking for ways to eat a healthier and more <a href="https://theconversation.com/how-sustainable-is-your-weekly-grocery-shop-these-small-changes-can-have-big-benefits-234367">sustainable diet</a>. And one way to do this is by reducing the amount of meat we eat. That doesn’t mean you need to become a <a href="https://theconversation.com/why-you-should-eat-a-plant-based-diet-but-that-doesnt-mean-being-a-vegetarian-78470">vegan or vegetarian</a>. Our <a href="https://jn.nutrition.org/article/S0022-3166(24)00333-X/fulltext">recent research</a> shows even small changes to cut down on meat consumption could help improve health and wellbeing. But not all plant-based options are created equal and some are <a href="https://pubmed.ncbi.nlm.nih.gov/30744710/">ultra-processed</a>. Navigating what’s available when eating out – including options like tofu and fake meats – can be a challenge. So what are your best options at a cafe or restaurant? Here are some guiding principles to keep in mind when cutting down on meat. <h2>Health benefits to cutting down</h2> Small amounts of lean meat can be part of a healthy, balanced diet. But the majority of Australians <a href="https://cancer.org.au/about-us/policy-and-advocacy/prevention/obesity/related-resources/meat-and-cancer#consumption">still eat more meat</a> than recommended. Only a small percentage of Australians (10%) are vegetarian or vegan. But an <a href="https://www.foodfrontier.org/wp-content/uploads/2019/10/Food-Frontier-Hungry-For-Plant-Based-Australian-Consumer-Insights.pdf">increasing</a> number opt for a <a href="https://theconversation.com/love-meat-too-much-to-be-vegetarian-go-flexitarian-73741">flexitarian</a> diet. <a href="https://theconversation.com/whats-the-difference-between-vegan-and-vegetarian-225275">Flexitarians</a> eat a diet rich in fruits and vegetables, while still enjoying small amounts of meat, dairy, eggs and fish. Our <a href="https://jn.nutrition.org/article/S0022-3166(24)00333-X/fulltext">recent research</a> looked at whether the average Australian diet would improve if we swapped meat and dairy for plant-based alternatives, and the results were promising. The study found health benefits when people halved the amount of meat and dairy they ate and replaced them with healthy plant-based foods, like tofu or <a href="https://www.heartfoundation.org.au/blog/why-you-need-legumes-in-your-life">legumes</a>. On average, their dietary fibre intake – which helps with feeling fuller for longer and digestive health – went up. Saturated fats – which increase our blood cholesterol levels, a risk factor for heart disease – went down. Including more fibre and less saturated fat helps reduce the risk of <a href="https://www.heartfoundation.org.au/healthy-living/healthy-eating/healthy-eating-to-protect-your-heart">heart disease</a>. Achieving these health benefits may be as simple as swapping ham for baked beans in a toastie for lunch, or substituting half of the mince in your bolognese for lentils at dinner. <h2>How it’s made matters</h2> For a long time we’ve known processed meats – such as ham, bacon and sausages – are bad for your health. Eating high amounts of these foods is associated with poor <a href="https://www.heartfoundation.org.au/healthy-living/healthy-eating/protein-and-heart-health">heart health</a> and some forms of <a href="https://cancer.org.au/cancer-information/causes-and-prevention/diet-and-exercise/meat-and-cancer-risk">cancer</a>. But the same can be true of many processed meat alternatives. Plant-based alternatives designed to mimic meat, such as sausages and burgers, have become readily available in supermarkets, cafes and restaurants. These products are ultra-processed and can be <a href="https://theconversation.com/we-looked-at-700-plant-based-foods-to-see-how-healthy-they-really-are-heres-what-we-found-222991">high in salt and saturated fat</a>. Our study found when people replaced meat and dairy with ultra-processed meat alternatives – such as plant-based burgers or sausages – they ate more salt and less calcium, compared to eating meat or healthy plant-based options. So if you’re cutting down on meat for health reasons, it’s important to think about what you’re replacing it with. The <a href="https://www.eatforhealth.gov.au/sites/default/files/2022-09/n55g_adult_brochure.pdf">Australian Dietary Guidelines</a> recommend eggs, legumes/beans, tofu, nuts and seeds. Tofu can be a great option. But we recommend flavouring plain tofu with herbs and spices yourself, as pre-marinated products are often ultra-processed and can be high in salt. <h2>What about when dining out?</h2> When you’re making your own food, it’s easier to adapt recipes or reduce the amount of meat. But when faced with a menu, it can be difficult to work out what is the best option. Here are our four ways to make healthy choices when you eat out: 1. Fill half your plate with vegetables When cutting down on meat, aim for half your plate to be vegetables. Try to also eat <a href="https://theconversation.com/were-told-to-eat-a-rainbow-of-fruit-and-vegetables-heres-what-each-colour-does-in-our-body-191337">a variety of colours</a>, such as leafy green spinach, red capsicum and pumpkin. When you’re out, this might look like choosing a vegetable-based entree, a stir-fry or ordering a side salad to have with your meal. 2. Avoid the deep fryer The Australian Dietary Guidelines <a href="https://www.eatforhealth.gov.au/sites/default/files/files/the_guidelines/n55a_australian_dietary_guidelines_summary_130530.pdf">recommend limiting</a> deep fried foods to once a week or less. When dining out, choose plant-based options that are sautéed, grilled, baked, steamed, boiled or poached – instead of those that are crumbed or battered before deep frying. This could mean choosing vegetarian dumplings that are steamed not fried, or poached eggs at brunch instead of fried. Ordering a side of roast vegetables instead of hot chips is also a great option. 3. Pick wholegrains Scan the menu for wholegrain options such as brown rice, wholemeal pizza or pasta, barley, quinoa or wholemeal burger buns. Not only are they good sources of protein, but they also provide more <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/grain-cereal-foods-mostly-wholegrain-and-or-high-cereal-fibre">dietary fibre</a> than refined grains, which help keep you fuller for longer. 4. If you do pick meat – choose less processed kinds You may not always want, or be able, to make a vegetarian choice when eating out and with other people. If you do opt for meat, it’s better to steer clear of processed options like bacon or sausages. If sharing dishes with other people, you could try adding unprocessed plant-based options into the mix. For example, a curry with lentils or chickpeas, or a vegetable-based pizza instead of one with ham or salami. If that’s not an option, try choose meat that’s a lean cut, such as chicken breast, or options which are grilled rather than fried.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236505/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, PhD candidate at the Institute for Physical Activity and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, NHMRC Emerging Leadership Fellow and Senior Research Fellow at the Institute for Physical Activity and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

From maxing out to slowing down, how much do heart rates vary across sports?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> and <a href="https://theconversation.com/profiles/gregory-peoples-1556509">Gregory Peoples</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> A classic image of the Olympics and Paralympics is an athlete at the end of a race struggling for breath, their heart obviously racing. But at the other end of the scale are athletes such as archers and shooters, who need to slow their heart rates down as much as possible. Athletes in speed and endurance events regularly push their heart rate to the maximum. But these athletes usually have low heart rates at rest. What causes our heart rates and respiratory (breathing) rates to change so much, and is this healthy? <h2>When heart rates and respiratory rates rise</h2> If you are still and calm as you read this, your heart is probably beating 60–100 times per minute and you are likely breathing 12–20 times per minute. These are the <a href="https://theconversation.com/what-should-my-heart-rate-be-and-what-affects-it-98945">normal ranges for a resting adult</a>. During physical activity when muscles are contracting, the muscles need more oxygen to provide them with energy to work. To deliver this extra oxygen (<a href="https://theconversation.com/curious-kids-why-is-blood-red-229121#:%7E:text=Haemoglobin%20is%20like%20a%20red,oxygen%2C%20our%20blood%20is%20red.">carried in our blood</a>), our heart pumps blood faster. In other words, our heart rate increases. We also breathe faster to get more oxygen into our lungs to be delivered to the exercising muscles. <figure><iframe src="https://www.youtube.com/embed/3YOap5k0R_8?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Your resting heart rate can tell you plenty about your health and fitness.</figcaption></figure> <h2>How fast can our heart rate get during exercise?</h2> Aerobic means “with oxygen”. In <a href="https://my.clevelandclinic.org/health/articles/7050-aerobic-exercise">aerobic exercise</a> (“cardio”) you use large muscles repetitively and rhythmically. For example, walking, running, cycling, swimming and rowing. Muscles that are contracting during aerobic exercise use a lot of energy and need ten times <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4551211/">more oxygen than at rest</a>. High intensity aerobic events that involve large muscles or the entire body cause the highest heart rates. An <a href="https://www.heartonline.org.au/resources/calculators/target-heart-rate-calculator">estimate</a> of maximum heart rate (beats per minute) is 220 minus your age. This equates to 195 beats per minute for a 25-year-old – close to the average age of the Australian Olympic team of 26.5 years. Athletes competing in Olympic events of endurance or speed will reach their maximum heart rate. You can usually only maintain maximum heart rate for a few minutes. But in a 2000-metre rowing race, the rowers maintain intense effort at close to maximum heart rate for 6–8 minutes. This is one of the toughest events for the heart. It’s no wonder rowers often collapse in the boat <a href="https://www.bbc.com/news/uk-england-cambridgeshire-68731840">as they cross the finish line</a>. Highly trained endurance athletes can have a maximum heart rate higher than expected for their age. <a href="https://olympics.com/en/athletes/eliud-kipchoge">Eliud Kipchoge</a> from Kenya is considered the greatest marathon runner of all time. During his <a href="https://au.coros.com/stories?world-record">world record run</a> in the 2022 Berlin marathon, he ran with a heart rate of around 180 beats per minute for almost the entire race. <h2>How does breathing change with exercise?</h2> Our breathing changes with exercise to increase oxygen uptake from the air. At low-to-moderate intensity exercise, you start to take deeper breaths. This brings in more air and oxygen with each breath. However, there is a limit to how much the chest can expand. With higher intensity exercise, respiratory rate increases to increase oxygen intake. Elite athletes can breathe <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4818249/">more than 50 times</a> per minute. This is driven by <a href="https://theconversation.com/what-is-breathwork-and-do-i-need-to-do-it-231192">our diaphragm</a>, the most important muscle of breathing. <a href="https://www.abc.net.au/news/2024-07-28/paris-olympics-grace-brown-cycling-gold-medal-australia/104151466">Grace Brown</a>, Olympic gold medal cyclist in Paris, <a href="https://inscyd.com/article/grace-brown-olympic-gold-physiology/">breathes close to a maximal oxygen uptake</a> when she is cycling at high intensity. <h2>Some athletes need to slow things down</h2> Archery and shooting athletes perform better with a lower heart rate. They time their shots to be <a href="https://pubmed.ncbi.nlm.nih.gov/3580727/#:%7E:text=Results%20showed%20that%20the%20champion,both%20during%20diastole%20and%20systole">between heart beats</a> when the body is the most still. This is easier with a slower heart rate, with more time between beats. Archers consciously lower their heart rate <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6441821/">prior to shooting</a> by <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6721071/">slowing their breathing</a>. Other Olympians use <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10224217/#:%7E:text=For%20practicing%20slow%20and%20deep,minutes%20before%20starting%20the%20exercise.">breathing techniques</a> to calm pre-race anticipation and high heart rates. Slowing the breath, <a href="https://theconversation.com/what-is-breathwork-and-do-i-need-to-do-it-231192">especially the exhale</a>, is the best way to lower your heart rate. Beta-blockers also reduce heart rate, by blocking adrenaline. This is why they are on the <a href="https://www.wada-ama.org/en/prohibited-list">prohibited substances list</a> of the World Anti-Doping Agency. <h2>What about resting heart rates?</h2> Athletes often have a <a href="https://www.health.harvard.edu/heart-health/is-a-low-heart-rate-worrisome">low resting heart rate</a>, around 40-50 beats per minute, and slower during sleep. Some are even lower – five time Tour de France winner Miguel Indurain famously had a resting heart rate of <a href="https://www.cyclingweekly.com/fitness/miguel-indurain-vs-your-body-34288">28 beats per minute</a>. Legendary US swimmer Michael Phelps is the <a href="https://olympics.com/en/news/michael-phelps-olympic-medals-record-how-many-gold-swimmer-world-record">most successful Olympian</a> of all time – he had a resting heart rate of <a href="https://www.reanfoundation.org/low-resting-heart-rate-and-lifespan/#:%7E:text=Studies%20on%20Athletes%20and%20Low%20Resting%20Heart%20Rate&text=It%20could%20also%20hint%20at,BPM%20throughout%20his%20professional%20career">less than 40 beats per minute</a>. Regular moderate-to-vigorous intensity aerobic exercise makes the <a href="https://www.medicalnewstoday.com/articles/athletes-heart-rate">heart stronger and more efficient</a>. A stronger heart pumps more blood per beat, which means it doesn’t need to beat as often. Exercise also <a href="https://pubmed.ncbi.nlm.nih.gov/12477376/">increases vagus nerve</a> activity to the heart and <a href="https://www.nature.com/articles/ncomms4775">slows down</a> the heart’s pacemaker cells. These both reduce heart rate. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6306777/">A large review</a> found endurance training and yoga were the best exercises to reduce resting heart rate. But training needs to be maintained to keep resting heart rate low. When elite athletes reduced their training volume by half during COVID lockdown, their <a href="https://www.mdpi.com/2071-1050/13/5/2970">resting heart rate increased</a>. <h2>What does this mean for our health?</h2> A slower resting heart rate is linked to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6306777/">longer life expectancy and reduced death from cardiovascular disease</a>. Indeed, <a href="https://bjsm.bmj.com/content/55/4/206">a study</a> of more than 8,000 Olympians from the United States found they lived longer than the general population. So it is healthy to do activities that increase your heart rate in the short-term, whether as an Olympian or Paralympian competing, or a fan with your heart racing watching a gold medal event.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/235594/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, Associate professor of Medical Sciences, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> and <a href="https://theconversation.com/profiles/gregory-peoples-1556509">Gregory Peoples</a>, Senior Lecturer - Physiology, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Gold medallist breaks down in tears over her late father's note

An Olympic gold medallist has broken down in tears as she recalled an emotional and poignant exchange she had with her father before he died of cancer. Lola Anderson claimed the gold medal for Team Great Britain in rowing, beating The Netherlands by just 0.15 seconds in the women’s quadruple sculls. In her victory interview with the <a href="https://www.bbc.com/news/articles/cnd06pg0k0wo" target="_blank" rel="noopener">BBC</a>, Lola recalled a note her father Don had given her months before his death in 2019. Before his death, Lola's father asked her to retrieve a safety deposit box that contained an old diary entry that Lola wrote when she was just 14 years old. In it, she wrote about becoming an Olympic rowing champion after seeing Helen Glover win gold at London 2012. The note read: “My name is Lola Anderson and I think it would be my biggest dream in life to go to the Olympics and represent Team GB in rowing and, if possible, win a gold medal.” Lola soon threw the note in the bin as she started to doubt her dream, but unbeknownst to her, her father fished it out of the garbage and kept it, giving it back to her before he died. When asked about the note after the win, she told the BBC, “I’d forgotten about it obviously. A couple years ago my dad reminded me." “I know he’d be so, so proud. I’m just thinking a lot about him right now, it’s really lovely.” Speaking about the note to the <a href="https://www.theguardian.com/sport/article/2024/jul/26/he-chose-to-believe-meet-lola-anderson-gb-rower-living-her-late-fathers-olympic-dream" target="_blank" rel="noopener">Guardian</a> before the Olympics, Anderson said her father, who introduced her to the sport, believed in her when she didn’t. “I kinda thought that was a really cocky, arrogant thing to have written. Back then, on a good day I wasn’t capsizing. I ripped the page out and threw it in the bin,” she said. “It reflects to me how much he cared, invested and believed in me and my siblings, even when we couldn’t see it. There was nothing to show I had any talent when I first started rowing but he kept the note and chose to believe.” Image credits: BBC

Walking or running: for the same distance, which consumes more energy?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/clement-lemineur-1529211">Clément Lemineur</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>; <a href="https://theconversation.com/profiles/clement-naveilhan-1495411">Clément Naveilhan</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>, and <a href="https://theconversation.com/profiles/francois-dernoncourt-1495410">François Dernoncourt</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a> It’s Monday morning, the alarm goes off and it’s already 7:30 a.m. – and you’re 30 minutes late. Normally you need 45 minutes to walk the 3 kilometres to work, but this morning you’ll be running for 20 minutes. Yes, but by lunchtime you’re feeling more tired and you have the impression that you’ve expended more energy than usual on the trip. Yet you’ve covered the same distance as on the other days. How can this be? The calorie expenditure associated with any activity is called the “metabolic cost”, and corresponds to the energy consumed by our organs to cover a given distance. This metabolic cost can be determined by analysing the oxygen our bodies consume and the carbon dioxide they produce, we can estimate the amount of energy expended, and thus the metabolic cost. It was using this method that <a href="https://pubmed.ncbi.nlm.nih.gov/692303/">researchers had already answered our question back in the 1970s</a>. Perhaps not surprisingly, running consumes more energy than walking for the same distance covered. But why? <h2>Energy lost when running</h2> Imagine you’re watching someone running. Now look closely at the vertical movement (up and down) of their pelvis and head. As you can see from the diagram below, when we run, the distance that our body moves up and down is greater than when we walk. To produce this vertical movement, the muscles of the lower limbs have to generate more force, and that consumes more energy, yet doesn’t bring us any closer to our destination. So when running, part of the energy expended is used to move our bodies <a href="https://pubmed.ncbi.nlm.nih.gov/16029949/">upward rather than forward</a>. The energy needed to cover those 3 km is therefore higher for running than for walking. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=287&fit=crop&dpr=1 600w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=287&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=287&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=361&fit=crop&dpr=1 754w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=361&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=361&fit=crop&dpr=3 2262w" alt="Illustration of the oscillations of running and walking" /></a><figcaption>Running involves much greater vertical oscillation of the centre of mass than walking. This is the main reason why running consumes more energy than walking for the same distance covered. François Dernoncourt, Fourni par l'auteur</figcaption></figure> This difference between walking and running is not confined to what happens during the activity itself. In fact, each physical exercise causes a delayed expenditure of energy, which is added to the expenditure during the activity. Taking this into account, it’s once again running that uses more energy than walking. Immediately after running your 3 km, the increased energy consumption (compared with resting) lasts for several minutes, mainly because of the increase in body temperature and the replenishment of energy reserves. This additional expenditure after running is <a href="https://pubmed.ncbi.nlm.nih.gov/22446673/">more than twice that observed after walking</a>, due to the difference in intensity between the two exercises. <h2>It all depends on speed</h2> Running therefore involves a higher calorie expenditure than walking for the same distance covered. But this is on condition that the walking speed considered is “normal” (around 5 km/h). So, if we walk very slowly, it will take us so long to cover the 3 km that the calorie expenditure will be greater in the end. This is because the body expends a certain amount of energy per unit of time no matter what, regardless of the activity performed (known as the “basal metabolic rate”). The same applies if the walking speed is very fast (<a href="https://pubmed.ncbi.nlm.nih.gov/29925582/">more than 8 km/h</a>): running is more energy-efficient. Here, the coordination required to walk at such a speed means that we need to activate our muscles more, without being able to take advantage of the elasticity of our tendons, as is the case with running. Moreover, we have a very precise intuitive perception of the energy efficiency of a particular style of movement. If we’re on a treadmill whose speed gradually increases, the point at which we spontaneously switch from walking to running coincides with the <a href="https://www.sciencedirect.com/science/article/pii/S096663622100120X">moment when it would become more energy-consuming to walk than to run</a>. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=395&fit=crop&dpr=1 600w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=395&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=395&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=497&fit=crop&dpr=1 754w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=497&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=497&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Modelling of metabolic cost (kilocalories expended per kilogram per kilometre covered) as a function of speed (kilometres per hour) for walking and running.

It’s at around this threshold speed that people spontaneously switch from walking to running. François Dernoncourt, Adapted from Summerside et al, Fourni par l'auteur</figcaption></figure> In conclusion, because of greater oscillation of the centre of mass and increased energy expenditure after exercise, running to work is more energy-intensive than covering the same distance by walking. But remember, whether you choose to walk or run to work, the most important thing is that you’re already saving energy!<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233943/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/clement-lemineur-1529211">Clément Lemineur</a>, Doctorant en Sciences du Mouvement Humain, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>; <a href="https://theconversation.com/profiles/clement-naveilhan-1495411">Clément Naveilhan</a>, Doctorant en Sciences du Mouvement Humain, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>, and <a href="https://theconversation.com/profiles/francois-dernoncourt-1495410">François Dernoncourt</a>, Doctorant en Sciences du Mouvement Humain, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Daughter of former All Black charged over alleged hit and run death

The daughter of former New Zealand All Black has been charged over an alleged hit and run that left a 65-year-old man dead in Auckland. Helena Jade Cribb, the daughter of Ron Cribb, was charged earlier this year after Jason Collins' body was found by a member of the public on O'Brien Rd, Lucas Heights in the early hours of December 7. The 22-year-old previously had a name suppression, which has now lapsed. Earlier this year, Detective Sergeant Ben Bergin said the driver allegedly involved had been identified not long after Collins' death. "A thorough investigation has been underway into the tragic circumstances by the Waitematā CIB and we have reached a point where charges have been filed," Bergin said. Collins has been remembered as a devoted father, husband and friend. "The tragic loss of Jason has left an unfillable void in our hearts," a statement on behalf of his family read. "...his absence is a constant ache, a relentless reminder of what we've lost. "Taken from us too soon, his departure is a profound and senseless blow that we struggle to comprehend. "Each day is a battle against the overwhelming emptiness left in his wake. "We ask for privacy at this time as we continue to grieve." The 22-year-old reportedly faces a charge of operating a vehicle carelessly, causing death while under the influence of alcohol or drugs. She is set to reappear in court in September.

"Felt like a criminal": Mother and disabled son "kicked out" of Pink concert

A distraught mother has taken to social media to recall the moment her and her seven-year-old son, who has Down syndrome, were asked to leave a concert venue. Vanessa Vasey, 48, spent over $1,000 to take her son Jesse to see Pink in London during her UK stadium tour, but when the pair arrived at the venue, things took a turn. Jesse struggled to stay still in his seat and was soon surrounded by "six security guards" who ordered the disabled boy to sit down, otherwise they would have to leave. She said she tried to explain her son’s condition to the guards but they ended up being “escorted from the premises” just as Pink took to the stage. On Facebook, Vasey wrote in detail about what happened, saying her son had been “robbed” of a special experience. “Music is his life and Pink is one of his absolute favourites,” she wrote. “We successfully saw her perform at BST Hyde Park last year and were thrilled to learn of her return again this year.” Vasey said she purchased more expensive “hospitality tickets” allowing people to move between bars and food outlets during the night “so that Jesse wouldn’t be pressured into remaining in one seat all night, as he gets overwhelmed in busy environments and finds it hard to sit still.” “We spent some time in the bar leading up to the main act, and Jesse was having a wonderful time, until about 45 minutes before Pink was due to come on, they suddenly shut all the blinds, obstructing us from seeing anything,” she wrote. “I tried to consult with the hospitality managers over this, and explained Jesse’s needs, but they wouldn’t budge on it. So not wanting Jesse to stare at a blind all night, we attempted to go into the seating zone." “We couldn’t get him to sit in his seat, but he was happy dancing and singing at the front railings, and even interacting with some of the other guests." “Doing no harm to anyone, or obstructing anyone’s view. This seemed OK for about half an hour or so. Then ... just as Pink dropped from the sky in her opening number, we had six security guards come into the zone and ask us to leave or sit in our seats.” Vasey said the security guards were “abrupt, intimidating and unpleasant”, as they "tried to force us to take Jesse to a sensory room which was soundproof, and watch Pink on a screen.” <div> </div> “Something we could do at home, robbing us of the whole experience, as if my son was some sort of inconvenience, and better off shut in a room out of sight.” When Vasey complained to venue staff, she claims that more security guards appeared and they had no choice but to leave. “We were escorted out of the building like criminals and saw no more of the Pink show. Jesse was utterly devastated, and they showed absolutely zero care or understanding." “Shame on you Tottenham Stadium,” she concluded. “My poor boy deserved so much better than this!” After UK media picked up Vasey's story, Tottenham Stadium released a statement explaining their actions. “Following further investigation, we can confirm that Ms Vasey was offered assistance by our Safeguarding and Welfare teams throughout the night to provide Jesse with a comfortable viewing experience, including access to our dedicated Sensory Room,” the statement read. “The offers of assistance were declined by Ms Vasey and the party chose to leave the event.” Vasey was soon set upon by online trolls who condemned her choice to take Jesse to the concert in the first place, to which she issues a lengthy statement about inclusivity and not singling people out for their disabilities. “Why do we take them [to events]? Because, as parents, we have the same dreams and aspirations for our children as any other parent,” she wrote. “We have the same desires to see our children’s faces light up, as any other parent would. Our children are exposed to the same world as other children, and they enjoy the same things." “They have the same likes and desires. The only thing that’s different is their needs, their abilities and their way of accessing their dreams." “Why should these things deny them of fulfilling these dreams and passions? This is meant to be a world of inclusion. So let’s start including!" “That means adapting, understanding, supporting and most importantly; changing the way we deliver these privileges so that they are privileges for all of us, and not just some of us.” Image credits: Facebook/Richard Isaac/Shutterstock Editorial

To-do list got you down? Understanding the psychology of goals can help tick things off – and keep you on track

<a href="https://theconversation.com/profiles/kim-m-caudwell-1258935">Kim M Caudwell</a>, <a href="https://theconversation.com/institutions/charles-darwin-university-1066">Charles Darwin University</a> It feels like we are living in busy times. According to the <a href="https://www.oecdbetterlifeindex.org/topics/work-life-balance/">OECD Better Life Index</a>, 12.5% of Australians report working at least 50 hours a week, higher than the OECD average. Many Australians are also <a href="https://www.abc.net.au/news/2023-08-03/multiple-job-holders-hit-record-high-abs/102679190">working more than one job to buffer against cost-of-living pressures</a>. Psychology has long been interested in our goals – our mental representations of desirable outcomes. Much of this research is on how we form, pursue and attain goals, plus how goals make us feel. Across studies, we see a consistent pattern of <a href="https://link.springer.com/article/10.1007/s10902-013-9493-0#Sec34">successful goal pursuit and wellbeing</a>. So, having time to work toward our goals is important. With this in mind, what is the best way to get things done – and how can we get better at achieving our goals, especially when we feel time poor? <h2>Make a list</h2> Most of us approach multiple goals with the age-old “to-do” list. First, you write down everything you need to do. Then you “check” or tick things off as you do them. One reason to-do lists are useful is because we are more likely to remember things we haven’t completed, rather than things we have. This is known as the <a href="https://www.youtube.com/watch?v=E-F1U4bV2m8">Zeigarnik effect</a>. While to-do lists are easy to write, they don’t always work. There are however <a href="https://hbr.org/2021/01/i-tried-4-to-do-list-methods-heres-what-worked">various approaches for to-do lists</a> that may improve their effectiveness. Another thing to consider is the wide range of apps, tools and platforms that can make tasks more fun and outsource mental load. Adding elements of game play like point scoring or competition – called “<a href="https://theconversation.com/how-gamification-could-revolutionise-creative-thinking-in-the-workplace-122852">gamification</a>” – can <a href="https://www.sciencedirect.com/science/article/pii/S0747563221002867">help people work toward goals in educational and work settings</a>. Similarly, app-based reminders can help people reach <a href="https://doi.org/10.1177/2047487320905717">physical rehabilitation goals and form good exercise habits</a>. <h2>Finding your why</h2> Researchers have focused a lot on the psychology of why people pursue goals – and how this affects their approach to tasks. For example, some people want to complete a university degree because they want to get a job. Others may be more interested in developing skills or knowledge. In both cases, there is a desired outcome – albeit with differing reasons. Our goals can be differentiated by who or what is driving them. Goals that feel like our own, and for which we experience a sense of intrinsic motivation, are known as “self-concordant”. These goals represent enduring personal interests, are aligned with values and are positively <a href="https://link.springer.com/article/10.1007/s12144-020-01156-7">linked to wellbeing</a>. <a href="https://link.springer.com/article/10.1007/s10648-006-9012-5">Goal orientation theory</a> offers a similar perspective. Using the same example, you may study so you score well on a test (a performance goal) or because you want to be sure you develop your knowledge (a mastery goal). Mastery goals tend to lead to <a href="https://link.springer.com/article/10.1007/s10869-010-9201-6">better results and self-regulation</a>. <h2>Juggling goals – 4 to-do tips</h2> So, what happens when we have multiple – perhaps even competing – goals, or goals that aren’t so enjoyable? We might want to finish writing a report or assignment, then read a few chapters of a textbook – but also go to the gym and binge a few episodes of our favourite TV show. In such scenarios, psychological science offers some insights into how we might stay task-focused, and on track to tick more items off our to-do list. 1. Beware the <a href="https://www.pwc.pl/en/articles/planning-fallacy-part-I-cognitive-traps.html">planning fallacy</a>. This happens when we underestimate the amount of resources (such as time) it will take to reach a goal. As writer and religious thinker William Penn put it: “Time is what we want most, but what we use worst”. Think through the all the steps and time required to complete your goal. 2. Monitor your progress. <a href="https://eprints.whiterose.ac.uk/91437/8/3_PDFsam_Does%20monitoring%20goal.pdf">Incorporating goal monitoring</a> into an activity can boost progress. And reviewing your estimations and expectations against your actual times and achievements can be used to calculate a “<a href="https://www.indeed.com/career-advice/career-development/estimating-time-for-tasks">fudge ratio</a>” to aid future planning. For instance, you could multiply your expected time on tasks by 1.5 to help buffer against the planning fallacy. 3. Focus on mastery. Self-concordant goals and tasks feel easier, and their underlying tasks may be <a href="https://journals.sagepub.com/doi/full/10.1177/0146167215575730">less subject to forgetting</a>. Tedious but necessary goals (such as doing the dishes or filling out forms) are less intrinsically motivating. This means <a href="https://www.emerald.com/insight/content/doi/10.1108/EBHRM-04-2014-0013/full/html#idm45933122746592">planning, reminders and support become more important to goal progress</a>. 4. Plan for derailments. People vary in their ability to plan and might forget to take a goal-directed action at an appropriate time (this could be one reason the <a href="https://www.sbs.com.au/news/article/the-streaming-services-winning-the-battle-for-attention-and-the-feature-australians-want/9crrpafgd">average Australian streams 27 hours of video each week</a>). <a href="https://www.tandfonline.com/doi/full/10.1080/10463283.2024.2334563">Implementation intentions</a> bring our attention back toward our goals by linking them to an environmental marker. These simple “if-then” plans are shown to <a href="https://cancercontrol.cancer.gov/brp/research/constructs/implementation-intentions#:%7E:text=Implementation%20intentions%20are%20formed%20for,might%20otherwise%20undermine%20goal%20striving.">help overcome issues with self-regulation</a>. Such a statement might be “if I see the ‘next episode’ icon appear, I will get up and turn off the TV so I can read a chapter of my textbook”. With time being frustratingly finite, it is inevitable we will run out of time to do all of the things on our to-do list. Finding an approach that works for us will take time and effort. But it’s probably a worthy goal in itself.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/230399/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/kim-m-caudwell-1258935">Kim M Caudwell</a>, Senior Lecturer - Psychology | Chair, Researchers in Behavioural Addictions, Alcohol and Drugs (BAAD), <a href="https://theconversation.com/institutions/charles-darwin-university-1066">Charles Darwin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Teen with Down Syndrome sets new world record

A 19-year-old teen with Down Syndrome has conquered the London Marathon and became a Guinness World Record after just five months of training. Lloyd Martin from Cardiff completed the 42.1 km course across the capital with his mother cheering him on. Guinness World Record has awarded him the certificate for becoming the youngest person in his learning disability category to finish a marathon. "I'm so excited to run London. I love being fit and healthy and I want to make my family and friends proud," the teenager said. Mum Ceri Hooper also told the BBC how proud she was of her son's accomplishment. "In Lloyd's words, it's achieving his dream," she said. "Really anything is possible if you put your mind to it. With a bit of work, you can achieve it." Recalling the experience, the proud mum said: "He ran continuously for 14 miles which is the longest he's ever run before." Although Lloyd walked for a bit after his 14-mile-long streak, the crowd cheered him on every step of the way, and despite the challenge the mother-and-son duo had "a ball". The pair were at a loss for words when he finally crossed the finish line and they both "burst into tears." Lloyd is also now the third Welsh Special Olympics athlete to compete in the London Marathon. Prior to completing the world-famous marathon, Lloyed had completed an astonishing 30 Parkruns. Until last Christmas the teenager had never run further than three miles, but his mother was determined to get him marathon-ready. Ceri, who has taken on the London Marathon four times, created a specialised training regime for her son which included weekly runs. Lloyd managed to secure a spot in the marathon thanks to the help of the Special Olympics GB, where he is also a footballer and a gymnast. Images: Facebook/ Twitter

Running or yoga can help beat depression, research shows – even if exercise is the last thing you feel like

<a href="https://theconversation.com/profiles/michael-noetel-147460">Michael Noetel</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> At least <a href="https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2021.665019/full">one in ten people</a> have depression at some point in their lives, with some estimates <a href="https://www.sciencedirect.com/science/article/pii/S0749379720301793">closer to one in four</a>. It’s one of the worst things for someone’s wellbeing – worse than <a href="https://www.happinessresearchinstitute.com/_files/ugd/928487_4a99b6e23f014f85b38495b7ab1ac24b.pdf">debt, divorce or diabetes</a>. <a href="https://theconversation.com/why-are-so-many-australians-taking-antidepressants-221857">One in seven</a> Australians take antidepressants. Psychologists are in <a href="https://theconversation.com/we-cant-solve-australias-mental-health-emergency-if-we-dont-train-enough-psychologists-here-are-5-fixes-190135">high demand</a>. Still, only <a href="http://dx.doi.org/10.1371/journal.pmed.1003901">half</a> of people with depression in high-income countries get treatment. Our <a href="https://www.bmj.com/content/384/bmj-2023-075847">new research</a> shows that exercise should be considered alongside therapy and antidepressants. It can be just as impactful in treating depression as therapy, but it matters what type of exercise you do and how you do it. <h2>Walk, run, lift, or dance away depression</h2> We found 218 randomised trials on exercise for depression, with 14,170 participants. We analysed them using a method called a network meta-analysis. This allowed us to see how different types of exercise compared, instead of lumping all types together. We found walking, running, strength training, yoga and mixed aerobic exercise were about as effective as <a href="https://theconversation.com/explainer-what-is-cognitive-behaviour-therapy-37351">cognitive behaviour therapy</a> – one of the <a href="https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2018.00004/full">gold-standard treatments</a> for depression. The effects of dancing were also powerful. However, this came from analysing just five studies, mostly involving young women. Other exercise types had more evidence to back them. Walking, running, strength training, yoga and mixed aerobic exercise seemed more effective than antidepressant medication alone, and were about as effective as exercise alongside antidepressants. But of these exercises, people were most likely to stick with strength training and yoga. <iframe id="cZaWb" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/cZaWb/2/" width="100%" height="400px" frameborder="0"></iframe> Antidepressants certainly help <a href="https://www.thelancet.com/article/S0140-6736(17)32802-7/fulltext">some people</a>. And of course, anyone getting treatment for depression should talk to their doctor <a href="https://australia.cochrane.org/news/new-cochrane-review-explores-latest-evidence-approaches-stopping-long-term-antidepressants">before changing</a> what they are doing. Still, our evidence shows that if you have depression, you should get a psychologist and an exercise plan, whether or not you’re taking antidepressants. <h2>Join a program and go hard (with support)</h2> Before we analysed the data, we thought people with depression might need to “ease into it” with generic advice, <a href="https://www.who.int/initiatives/behealthy/physical-activity">such as</a> “some physical activity is better than doing none.” But we found it was far better to have a clear program that aimed to push you, at least a little. Programs with clear structure worked better, compared with those that gave people lots of freedom. Exercising by yourself might also make it hard to set the bar at the right level, given low self-esteem is a symptom of depression. We also found it didn’t matter how much people exercised, in terms of sessions or minutes a week. It also didn’t really matter how long the exercise program lasted. What mattered was the intensity of the exercise: the higher the intensity, the better the results. <h2>Yes, it’s hard to keep motivated</h2> We should exercise caution in interpreting the findings. Unlike drug trials, participants in exercise trials know which “treatment” they’ve been randomised to receive, so this may skew the results. Many people with depression have physical, psychological or social barriers to participating in formal exercise programs. And getting support to exercise isn’t free. We also still don’t know the best way to stay motivated to exercise, which can be even harder if you have depression. Our study tried to find out whether things like setting exercise goals helped, but we couldn’t get a clear result. Other reviews found it’s important to have a <a href="https://pubmed.ncbi.nlm.nih.gov/31923898/">clear action plan</a> (for example, putting exercise in your calendar) and to <a href="https://pubmed.ncbi.nlm.nih.gov/19916637/">track your progress</a> (for example, using an app or smartwatch). But predicting which of these interventions work is notoriously difficult. A <a href="https://www.nature.com/articles/s41586-021-04128-4">2021 mega-study</a> of more than 60,000 gym-goers <a href="https://www.nature.com/articles/s41586-021-04128-4/figures/1">found</a> experts struggled to predict which strategies might get people into the gym more often. Even making workouts fun didn’t seem to motivate people. However, listening to audiobooks while exercising helped a lot, which no experts predicted. Still, we can be confident that people benefit from personalised support and accountability. The support helps overcome the hurdles they’re sure to hit. The accountability keeps people going even when their brains are telling them to avoid it. So, when starting out, it seems wise to avoid going it alone. Instead: <ul> <li> join a fitness group or yoga studio </li> <li> get a trainer or an exercise physiologist </li> <li> ask a friend or family member to go for a walk with you. </li> </ul> Taking a few steps towards getting that support makes it more likely you’ll keep exercising. <h2>Let’s make this official</h2> Some countries see exercise as a backup plan for treating depression. For example, the American Psychological Association only <a href="https://www.apa.org/depression-guideline/">conditionally recommends</a> exercise as a “complementary and alternative treatment” when “psychotherapy or pharmacotherapy is either ineffective or unacceptable”. Based on our research, this recommendation is withholding a potent treatment from many people who need it. In contrast, The Royal Australian and New Zealand College of Psychiatrists <a href="https://www.ranzcp.org/getmedia/a4678cf4-91f5-4746-99d4-03dc7379ae51/mood-disorders-clinical-practice-guideline-2020.pdf">recommends</a> vigorous aerobic activity at least two to three times a week for all people with depression. Given how common depression is, and the number failing to receive care, other countries should follow suit and recommend exercise alongside front-line treatments for depression.

Run out of butter or eggs? Here’s the science behind substitute ingredients

<a href="https://theconversation.com/profiles/paulomi-polly-burey-404695">Paulomi (Polly) Burey</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> It’s an all too common situation – you’re busy cooking or baking to a recipe when you open the cupboard and suddenly realise you are missing an ingredient. Unless you can immediately run to the shops, this can leave you scrambling for a substitute that can perform a similar function. Thankfully, such substitutes can be more successful than you’d expect. There are a few reasons why certain ingredient substitutions work so well. This is usually to do with the chemistry and the physical features having enough similarity to the original ingredient to still do the job appropriately. Let’s delve into some common ingredient substitutions and why they work – or need to be tweaked. <iframe id="IitfH" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/IitfH/1/" width="100%" height="400px" frameborder="0"></iframe> <h2>Oils versus butter</h2> Both butter and oils belong to a chemical class called <a href="https://chem.libretexts.org/Bookshelves/Introductory_Chemistry/Map%3A_Fundamentals_of_General_Organic_and_Biological_Chemistry_(McMurry_et_al.)/23%3A_Lipids/23.01%3A_Structure_and_Classification_of_Lipids">lipids</a>. It encompasses solid, semi-solid and liquid fats. In a baked product the “job” of these ingredients is to provide flavour and influence the structure and texture of the finished item. In cake batters, lipids contribute to creating an emulsion structure – this means combining two liquids that wouldn’t usually mix. In the baking process, this helps to create a light, fluffy crumb. One of the primary differences between butter and oil is that butter is only about 80% lipid (the rest being water), while <a href="https://www.nutritionadvance.com/types-of-cooking-fats-and-oils/">oil is almost 100% lipid</a>. Oil creates a softer crumb but is still a great fat to bake with. You can use a wide range of oils from different sources, such as olive oil, rice bran, avocado, peanut, coconut, macadamia and many more. Each of these may impart different flavours. Other “butters”, such as peanut and cashew butter, aren’t strictly butters but pastes. They impart different characteristics and can’t easily replace dairy butter, unless you also add extra oil. <h2>Aquafaba or flaxseed versus eggs</h2> Aquafaba is the liquid you drain from a can of legumes – such as chickpeas or lentils. It contains proteins, kind of how egg white also contains proteins. The proteins in egg white include albumins, and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5912395/">aquafaba also contains albumins</a>. This is why it is possible to make meringue from egg whites, or from aquafaba if you’re after a vegan version. The proteins act as a foam stabiliser – they hold the light, airy texture in the product. The concentration of protein in egg white is a bit higher, so it doesn’t take long to create a stable foam. Aquafaba requires more whipping to create a meringue-like foam, but it will bake in a similar way. Another albumin-containing alternative for eggs is <a href="https://foodstruct.com/compare/seeds-flaxseed-vs-egg">flaxseed</a>. These seeds form a thick gel texture when mixed with a little water. The texture is similar to raw egg and can provide structure and emulsification in baked recipes that call for a small amount of egg white. <h2>Lemon plus dairy versus buttermilk</h2> Buttermilk is the liquid left over after churning butter – it can be made from sweet cream, cultured/sour cream or whey-based cream. Buttermilk mostly <a href="https://www.journalofdairyscience.org/article/S0022-0302(06)72115-4/fulltext">contains proteins and fats</a>. Cultured buttermilk has a somewhat tangy flavour. Slightly soured milk can be a good substitute as it contains similar components and isn’t too different from “real” buttermilk, chemically speaking. One way to achieve slightly soured milk is by adding some lemon juice or cream of tartar to milk. Buttermilk is used in pancakes and baked goods to give extra height or volume. This is because the acidic (sour) components of buttermilk interact with baking soda, producing a light and airy texture. Buttermilk can also influence flavour, imparting a slightly tangy taste to pancakes and baked goods. It can also be used in sauces and dressings if you’re looking for a lightly acidic touch. <h2>Honey versus sugar</h2> Honey is a <a href="https://resources.perkinelmer.com/lab-solutions/resources/docs/APP_Analysis-of-Sugars-in-Honey-012101_01.pdf">complex sugar-based syrup</a> that includes floral or botanical flavours and aromas. Honey can be used in cooking and baking, adding both flavour and texture (viscosity, softness) to a wide range of products. If you add honey instead of regular sugar in baked goods, keep in mind that honey imparts a softer, moister texture. This is because it contains more moisture and is a humectant (that is, it likes to hold on to water). It is also less crystalline than sugar, unless you leave it to crystallise. The intensity of sweetness can also be different – some people find honey is sweeter than its granular counterpart, so you will want to adjust your recipes accordingly. <h2>Gluten-free versus regular flour</h2> Sometimes you need to make substitutions to avoid allergens, such as gluten – the protein found in cereal grains such as wheat, rye, barley and others. Unfortunately, gluten is also the component that gives a nice, stretchy, squishy quality to bread. To build this characteristic in a gluten-free product, it’s necessary to have a mixture of ingredients that work together to mimic this texture. Common ingredients used are corn or rice flour, xanthan gum, which acts as a binder and moisture holder, and tapioca starch, which is a good water absorbent and can aid with binding the dough. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/202036/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/paulomi-polly-burey-404695">Paulomi (Polly) Burey</a>, Associate Professor (Food Science), <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

15 hacks that make running errands so much better

Run errands during the week More than 90 per cent of people do errands on the weekends, meaning shops will be packed and traffic will be a nightmare. Running errands on a weeknight will get you in and out in half the time. Once the kids are in bed, have one parent stay home while the other drives to the shops. You’ll miss the crowds and keep your weekend free for fun and family. Turn on a podcast Radio music – and its deejays and commercials – can get intense. Switch off the FM and plug in your phone so you can listen to a podcast or audiobook. You’ll be more relaxed, and the time will fly as you get engrossed in the story. Make the most of your time Never run out for just one task. Save time, petrol, and stress by getting more than one thing done when you’re out of the house. After dropping your child off at soccer practice, drop off your dry cleaning or pick up the milk from the supermarket. Set up an errand centre in your home Keeping all the objects you’ll need to complete your errands – packages to be mailed, dry cleaning to be delivered, library books to be returned – in one place will make it easy to get out the door when you get the chance. Designate a space by the door or in your car as a visual reminder of what needs to get done. Buy in bulk Picking up big batches of items like toilet paper, dog food, and tampons means fewer trips to the supermarket and less time running errands. Plus, you save money by buying bulk packages or stocking up while the items are on sale. Use long lines for "me time" Instead of griping about how long your wait to the cash register is, think of it as a few peaceful moments to yourself. Close your eyes (don’t be self-conscious!) and imagine yourself sitting on a quiet beach or getting a massage. Take several deep breaths while you mentally escape to that place. You’ll be much more relaxed, and you can wait in line with less frustration. Practice mindfulness Performing a ‘walking meditation’ while you shop will keep you engaged with your task instead of letting your mind wander to other stressors. By the end of your trip, you’ll have more energy and less frustration. Pay attention to the bright colours of the produce, the scents wafting from the bakery, and the feeling of each step you take. Do someone else's errands If you have an elderly neighbour or know a mother with young kids, offer to add some of their tasks to your to-do list. Studies have shown that helping others can reduce stress. Tune out Instead of drowning out your thoughts with music, keep the radio off when you’re driving and allow your own thoughts to come to you. The stimuli of everyday life can be overwhelming, so this is your chance to recharge your energy in the silence. Keep a grocery list on your phone You probably buy the same things on most of your grocery runs. Instead of writing a new list every week, keep an ongoing list on your phone, which makes it easy to add and remove items. Organise your list in the order you’ll find them at the supermarket. For instance, if you start near the produce section, write the fruits and vegetables first. Reward yourself To keep yourself motivated while you’re out, add a little luxury to your shopping list. Treat yourself with nice bath soap, a bouquet of flowers, or your favourite craft beer. Keep an ongoing errands list Write down your usual tasks, along with the ones you keep forgetting to do, like buying socks for your child or making a vet appointment for the dog, in a notepad. Carry it with you so you don’t miss anything when you’re out. When you’re home, stash it where the rest of your family can access it and jot down their needs. Buy online as much as possible The possibilities are endless: order groceries, buy stamps, cash checks, and renew library books online. Giving your credit card number over a secured server is safer than stating your number over the phone, and sometimes safer than handing your card over at a store. Alternate tasks with your neighbours Make a deal with your neighbours in which you do the grocery shopping one week, and they take care of it the next. You can watch each other’s kids when it’s your turn to stay home, and both of you will make fewer trips to the supermarket. Or plan to go grocery shopping with a friend. You’ll have more fun with the social support, and your kids might behave better with someone else present. Have dad run errands with the kids Kids who cook, clean, and run errands with their dads have more friends and are better behaved, according to a University of California study. Make sure your partner (or you, if you’re a dad) takes the kids along every now and then. As a bonus, wives of men who do chores with their kids find their husbands more attractive.

9 beauty hacks for when you’re running late

Spritz on dry shampoo When you don’t have time to wash or blow-dry your hair, dry shampoo is your new best friend. One quick spritz is a shortcut to volume and oil-free hair. Simply spray the dry shampoo directly at the roots and massage in for a clean, tousled look. Beauty expert and blogger, Jeanette Zinno, shares her special trick, “Use a dry shampoo at night to wake up with fresh textured hair. It has all night to work and absorb.” If you’re in a pinch and don’t have any dry shampoo on hand, run a dryer sheet across your hair, suggests Rochelle Maribojoc from Spa Pechanga. Though it sounds strange, it effectively picks up static, dirt, and oil; even if you plan on throwing your hair into a ponytail or messy bun, it’ll look leagues better. Stock up on travel-size products If you’re constantly running late (hey – no judgments!), having a to-go makeup bag full of mini hair and makeup products at the ready is a lifesaver. On those harried mornings, simply grab this trusty tote and do your beauty routine on the fly (on the train or when you get to your office). Makeup artists, Sam & Nic Chapman, share, “Travel-ready products are fantastic in a bind. If you haven’t had enough time to perfect your look in the morning, you’ll have the tools to freshen it up throughout the day.” Take advantage of multipurpose products Multi-purpose products help reduce the number of products you use and can be applied in less time. For example, a colour stick the can be used for cheeks, eyes, and lips. “I love it because it’s also very small, so you can take it on-the-go too,” Zinno says. Dry nail polish fast with ice water We’ve all been there – you’re going to an event or getting ready for a date, and you didn’t have time for a manicure. Of course, there’s no such thing as speedily painting your nails, as polish requires ample drying time, except, that is, if you use this brilliant trick from Zinno. “Soak your freshly-painted nails in a bowl of ice water for a minute; the cold will dry them quickly. Make sure you have the bowl ready before you paint your nails so you don’t mess them up!” Skip the foundation Unless your skin has a lot of unevenness, you really don’t need foundation 24/7. When you’re in a hurry, you can get away with dabbing concealer under eyes, down the bridge of the nose, on your chin, and on any problem areas like dark spots or pimples. “Using your concealer for spot-concealing is the best time-saver as it provides evenness of tone, while giving your complexion a natural, not-fussy look,” says CEO of Veil Cosmetics, Sébastien Tardif, who adds that you want to pick a concealer that matches your skin tone for the most flattering finish. Apply eyeliner on the "negative space" While cat liner and smoky eyes require a time commitment, filling in the negative space (the area of skin on your eyelid between your lashes and eye) is extremely easy and gives instant definition and make your lashes look fuller without any mascara. Smudge eyeliner for an instant smoky eye For the quickest smoky eye, “Simply line your eyes using a creamy eyeliner and smudge with your ring finger (it’s the weakest, so it’s the best for blending without pulling your delicate eyelid skin),” shares beauty expert and professional makeup artist, Sona Gasparian, “In just a few seconds, you’ll have a simple Parisian look!” Blush is a must Although contouring your full face will eat up too much time, blush is too important to skip, especially in the morning when most of us tend to roll out of bed looking pasty or sallow. If you’re super tight on time, dab a tinted lip balm on your cheeks and blend for a creamy blush alternative. “A little bit of colour on our cheeks can go a long way – the colour makes you look more alive without barely even trying,” says BH Cosmetics. Swipe on a dark lip colour A red, plum, or sophisticated brown lip hue can elevate your look and make others think you dedicated a whole lot of effort on your appearance, even when you didn’t. Choose a lip stain and you won’t even have to re-apply throughout the day, says Liz Fuller from Makeup Artistry Inc, “One quick pat on the lips in the morning as you’re running out the door, and you can forget about it for the remainder of the day.” Image credits: Getty Images This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/beauty/9-beauty-hacks-for-when-youre-running-late" target="_blank" rel="noopener">Reader's Digest</a>.

Body language expert breaks down royal family's Christmas card

A body language expert has broken down the subtle meanings and messages hidden in the royal family's Christmas card. On Monday, Prince William and Kate Middleton shared their 2023 Christmas card portrait, which features the Prince and Princess of Wales and their three children in a charming black and white photo. While their family portrait was met with <a href="https://oversixty.com.au/lifestyle/family-pets/blah-brutal-reactions-to-royal-family-s-2023-christmas-card" target="_blank" rel="noopener">mixed reactions</a>, royal fans wasted no time in praising the family for their charming photo.

Judi went on to say that their choice of relaxed outfits - jeans and white button-up shirts - would be an intentional choice as they show "the strength and total confidence of the pared-down family brand here, without all the trimmings and trappings of their royal status." As she notes, "We know they look superb in formalwear and royal regalia but this is the casual and much more relatable version." Judi also claims that Prince William's slight head tilt "suggests a desire to be liked", while "Kate leans into William’s torso to make this a subtly romantic pose too." Meanwhile, according to Judi, the position of Princess Charlotte right in the middle of the family could be intentional, who says "Charlotte looks so much like the late Queen and this central status-rich pose and beautiful smile are like echoes of Elizabeth when she was young." "This effect doesn’t look deliberate but it is still a rather moving message from this family Christmas card." Image credits: Getty Images

Selfie-taking tourists launched from Venice gondola after refusing to sit down

A group of rowdy tourists have ended up in the waters of a Venice canal after causing a ruckus onboard the boat. Six passengers were travelling on a canal in the Italian hotspot when the boat was heading towards a low bridge that they needed to pass under. The gondolier explained to the tourists that they needed to sit down and be still as the boat passed under the bridge, explaining that a change in weight would cause an issue. Despite the gondolier's warning, the tourists continued to stand up and move around the narrow vessel to take selfies of their journey. Predictably, ignoring the requests of the gondolier caused the vessel to capsize, sending the tourists into the freezing water as the gondolier jumped to safety. <iframe style="border: none; overflow: hidden;" src="https://www.facebook.com/plugins/video.php?height=314&href=https%3A%2F%2Fwww.facebook.com%2FSkyNewsAustralia%2Fvideos%2F854034223389998%2F&show_text=false&width=560&t=0" width="560" height="314" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe> No one was injured in the mishap, as the tourists swam to safety at the bank of the canal, before seeking refuge at La Fenice theatre, according to Venice police. According to a spokesman for the city’s gondola association, the gondola was not damaged, although the upholstered furniture in the vessel was ruined by the water. The spokesperson went on to confirm that the gondolier had instructed the tourists not to move around or stand up to take selfies during the manoeuvre, but due to a language barrier, the tourists did not comply. A video of the incident was posted to an Instagram page called Venezia Non è Disneyland (Venice Is Not Disneyland), an account run by young locals to chronicle tourism in the city, with the video being flooded with comments about the misbehaved tourists. Many Italian locals were quick to point out how rowdy the tourists must've been to cause the incident, with many pointing out they "didn't know it was possible to capsize a gondola".

Slimmed down Oprah addresses Ozempic rumours

Oprah Winfrey has addressed rumours about her impressive weight loss on the red carpet. The TV icon stunned at the premiere for the reboot of The Color Purple, walking the red carpet in a figure-hugging purple dress in Los Angeles on Wednesday night. While doing an interview with <a href="https://www.etonline.com/oprah-winfrey-reacts-to-her-physical-transformation-at-the-color-purple-premiere-exclusive-216118" target="_blank" rel="noopener">Entertainment Tonight</a>, the 69-year-old spoke candidly about her body transformation. ET host Kevin Frazier told Winfrey she was looking “divine in purple” and then asked, “What’s going on? Because if this is WeightWatchers, please, sign me up tonight!” “Well it’s not one thing, it’s everything … and I intend to keep it that way,” she replied, noting that she “was on that treadmill” hours before the premiere kicked off. Oprah's admission comes after her drastic weight loss was the subject of many rumours, with many people questioning whether she had used the weight loss drug to slim down. The former TV host did admit that she had contemplated the controversial weight loss injections, but ultimately decided against using it. “When I first started hearing about the weight loss drugs, at the same time, I was going through knee surgery, and I felt, ‘I’ve got to do this on my own,’” she explained on an episode of Oprah Daily’s The Life You Want: The State of Weight, which featured a panel of obesity specialists. “Because if I take the drug, that’s the easy way out.” Oprah has long been an ambassador for Weight Watchers, and said in 2015 when she first partnered with the company that her new lifestyle is "a way of living that’s so freeing".
