Castor oil is all the rage among health influencers – what you need to know about this alternative remedy

<p><em><a href="https://theconversation.com/profiles/veronique-seidel-1542416">Veronique Seidel</a>, <a href="https://theconversation.com/institutions/university-of-strathclyde-1287"><em>University of Strathclyde</em></a></em></p> <p>Castor oil, which was once used by fascists in Italy as <a href="https://www.rcpe.ac.uk/remoteandruralremedies/activities/exhibitions/medicines.html#:%7E:text=Due%20to%20its%20use%20as,the%20bludgeon%20and%20castor%20oil'.">punishment</a> because of its quick-acting laxative effect, is now a weight-loss trend on TikTok. Not drinking it, but rubbing it on your belly.</p> <p>Influencers are also pouring it in their belly buttons and wrapping towels soaked in it around their midriff. They claim it can <a href="https://www.tiktok.com/@karinawaldron/video/7333667470756072709?lang=en">melt belly fat</a> and <a href="https://www.tiktok.com/@sarahjmce/video/7322670147473362207?lang=en&amp;q=castor%20oil&amp;t=1716463274921">help with bloating</a>.</p> <p>Castor oil – made from the beans of the castor plant – is an ancient medicine. References to it appear in an ancient Egyptian medical text called the <a href="https://www.nationalgeographic.com/premium/article/castor-oil-real-health-benefits">Ebers Papyrus</a> (1550BC). It was used as a laxative and to treat various skin conditions. Cleopatra is said to have <a href="https://www.washingtonpost.com/lifestyle/wellness/cleopatra-used-it-as-a-beauty-aid-now-castor-oil-is-staging-a-cosmetics-comeback/2019/07/05/2d457584-92c5-11e9-aadb-74e6b2b46f6a_story.html?itid=sr_1_4c3daa8b-2b15-41d9-9b45-f1b2af1d7cf7">used it</a> in her hair and to brighten the whites of her eyes.</p> <p>The odourless oil is rich in a fatty substance called ricinoleic acid that strongly stimulates bowel movements. Today, it is an approved <a href="https://dps.fda.gov/omuf/monographsearch/monograph_m007">over-the-counter remedy</a> in some countries for short-term constipation and is used for cleansing the bowel before medical examinations. However, there’s not much scientific evidence to indicate that this laxative effect is better than other commonly used laxatives, such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3862068/">senna</a> – which has also been used for centuries.</p> <p>Other reported traditional uses for the oil include as a cure for sore and itchy eyes, to relieve joint and period pain, and as a means to induce labour. But, again, the evidence for these things is scant.</p> <p>Castor oil isn’t just imbibed, it is also widely used in skin creams, hair conditioners and other cosmetic products, such as lipsticks. It is used to moisturise, soothe irritated skin and reduce the appearance of wrinkles. Its moisturising properties have been attributed to ricinoleic acid.</p> <p>As part of haircare products, it is said to help with hair loss and dandruff.</p> <p>But taking castor oil as a standalone product is not risk free. The main side-effects of imbibing the oil are abdominal cramps, vomiting, bloating and dizziness.</p> <p>Vulnerable people, such as the elderly, babies, pregnant or breastfeeding women, and those with liver or kidney failure should avoid taking castor oil. As should anyone with inflammatory bowel disease, appendicitis or gastrointestinal obstruction or perforation.</p> <p>The side-effects of castor oil can also be exacerbated in people with <a href="https://www.degruyter.com/document/doi/10.1515/jom-1988-880520/html">eating disorders</a> who may choose to use the oil to lose weight by speeding up the passage of food through the gut.</p> <p>However, if you want to apply the oil to your skin or scalp, proceed with caution. In some people, it can trigger an allergic reaction.</p> <p>It is always advised to apply a small amount of pure castor oil or a castor oil-containing cosmetic product onto a small patch of skin. If there is no allergic reaction after 24 hours, then it can be assumed that the product can be applied safely to a larger area of the body.</p> <p>Ultimately, though, there are generally safer and better remedies out there. And rubbing it on your belly – sadly – won’t melt the fat.<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/232782/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/veronique-seidel-1542416">Veronique Seidel</a>, Senior Lecturer, Pharmacy and Biomedical Sciences, <a href="https://theconversation.com/institutions/university-of-strathclyde-1287">University of Strathclyde</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

I can’t afford olive oil. What else can I use?

<p><em><a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a></em></p> <p>If you buy your olive oil in bulk, you’ve likely been in for a shock in recent weeks. Major supermarkets have been selling olive oil for up to A$65 for a four-litre tin, and up to $26 for a 750 millilitre bottle.</p> <p>We’ve been hearing about the health benefits of olive oil for years. And many of us are adding it to salads, or baking and frying with it.</p> <p>But during a cost-of-living crisis, these high prices can put olive oil out of reach.</p> <p>Let’s take a look at why olive oil is in demand, why it’s so expensive right now, and what to do until prices come down.</p> <h2>Remind me, why is olive oil so good for you?</h2> <p>Including olive oil in your diet can reduce your risk of developing type 2 diabetes and improve heart health through more favourable <a href="https://www.mdpi.com/2072-6643/12/6/1548">blood pressure</a>, <a href="https://www.mdpi.com/2072-6643/7/9/5356">inflammation</a> and <a href="https://www.sciencedirect.com/science/article/abs/pii/S0939475319302662">cholesterol levels</a>.</p> <p>This is largely because olive oil is high in <a href="https://www.mdpi.com/2072-6643/4/12/1989">monounsaturated fatty acids</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8300823/">polyphenols</a> (antioxidants).</p> <p>Some researchers have suggested you can get these benefits from consuming up to <a href="https://www.frontiersin.org/articles/10.3389/fnut.2022.1041203/full">20 grams a day</a>. That’s equivalent to about five teaspoons of olive oil.</p> <h2>Why is olive oil so expensive right now?</h2> <p>A European heatwave and drought have <a href="https://www.abc.net.au/news/rural/2024-04-27/olive-oil-alternatives-what-you-can-use-in-cooking/103761718">limited</a> Spanish and Italian producers’ ability to supply olive oil to international markets, including Australia.</p> <p>This has been coupled with an unusually cold and short growing season for Australian <a href="https://www.abc.net.au/news/rural/2023-08-02/record-olive-oil-price-set-to-increase-again/102675452">olive oil suppliers</a>.</p> <p>The lower-than-usual production and supply of olive oil, together with heightened demand from shoppers, means prices have gone up.</p> <h2>How can I make my olive oil go further?</h2> <p>Many households buy olive oil in large quantities because it is cheaper per litre. So, if you have some still in stock, you can make it go further by:</p> <ul> <li> <p><strong>storing it correctly</strong> – make sure the lid is on tightly and it’s kept in a cool, dark place, such as a pantry or cabinet. If stored this way, olive oil can typically last <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6218649/">12–18 months</a></p> </li> <li> <p><strong>using a spray</strong> – sprays distribute oil more evenly than pourers, using less olive oil overall. You could buy a spray bottle to fill from a large tin, as needed</p> </li> <li> <p><strong>straining or freezing it</strong> – if you have leftover olive oil after frying, strain it and reuse it for other fried dishes. You could also freeze this used oil in an airtight container, then thaw and fry with it later, without affecting the oil’s <a href="https://link.springer.com/article/10.1007/s00217-022-04078-9">taste and other characteristics</a>. But for dressings, only use fresh oil.</p> </li> </ul> <h2>I’ve run out of olive oil. What else can I use?</h2> <p>Here are some healthy and cheaper alternatives to olive oil:</p> <ul> <li> <p><strong>canola oil</strong> is a good alternative for frying. It’s relatively <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/canola-oil">low</a> in saturated fat so is generally considered healthy. Like olive oil, it is high in <a href="https://pubmed.ncbi.nlm.nih.gov/23731447/">healthy monounsaturated fats</a>. Cost? Up to $6 for a 750mL bottle (home brand is about half the price)</p> </li> <li> <p><strong>sunflower oil</strong> is a great alternative to use on salads or for frying. It has a mild flavour that does not overwhelm other ingredients. Some <a href="https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/conjugated-linoleic-acid-versus-higholeic-acid-sunflower-oil-effects-on-energy-metabolism-glucose-tolerance-blood-lipids-appetite-and-body-composition-in-regularly-exercising-individuals/6C035B5C6E9FD7C9D6D7F806ADA56983">studies</a> suggest using sunflower oil may help reduce your risk of heart disease by lowering LDL (bad) cholesterol and raising HDL (good) cholesterol. Cost? Up to $6.50 for a 750mL bottle (again, home brand is about half the price)</p> </li> <li> <p><strong>sesame oil</strong> has a nutty flavour. It’s good for Asian dressings, and frying. Light sesame oil is typically used as a neutral cooking oil, while the toasted type is used to flavour sauces. Sesame oil is <a href="https://onlinelibrary.wiley.com/doi/10.1002/ptr.6428">high in</a> antioxidants and has some anti-inflammatory properties. Sesame oil is generally sold in smaller bottles than canola or sunflower oil. Cost? Up to $5 for a 150mL bottle.</p> </li> </ul> <h2>How can I use less oil, generally?</h2> <p>Using less oil in your cooking could keep your meals healthy. Here are some alternatives and cooking techniques:</p> <ul> <li> <p><strong>use alternatives for baking</strong> – unless you are making an olive oil cake, if your recipe calls for a large quantity of oil, try using an alternative such as apple sauce, Greek yoghurt or mashed banana</p> </li> <li> <p><strong>use non-stick cookware</strong> – using high-quality, non-stick pots and pans reduces the need for oil when cooking, or means you don’t need oil at all</p> </li> <li> <p><strong>steam instead</strong> – steam vegetables, fish and poultry to retain nutrients and moisture without adding oil</p> </li> <li> <p><strong>bake or roast</strong> – potatoes, vegetables or chicken can be baked or roasted rather than fried. You can still achieve crispy textures without needing excessive oil</p> </li> <li> <p><strong>grill</strong> – the natural fats in meat and vegetables can help keep ingredients moist, without using oil</p> </li> <li> <p><strong>use stock</strong> – instead of sautéing vegetables in oil, try using vegetable broth or stock to add flavour</p> </li> <li> <p><strong>try vinegar or citrus</strong> – use vinegar or citrus juice (such as lemon or lime) to add flavour to salads, marinades and sauces without relying on oil</p> </li> <li> <p><strong>use natural moisture</strong> – use the natural moisture in ingredients such as tomatoes, onions and mushrooms to cook dishes without adding extra oil. They release moisture as they cook, helping to prevent sticking.<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/228788/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> </li> </ul> <p><em><a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, Professor of Community Health and Wellbeing, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, Accredited Practising Dietitian and Lecturer, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Drinking olive oil: a health and beauty elixir or celebrity fad in a shot glass?

Viral videos show influencers tossing back shots of cult olive oil brands, and proclaiming a wide range of health benefits from improving digestion to clearing up acne.</p> <p>Celebrity and influencers are sold on liquid gold but what about the rest of us? Can drinking olive oil really work on miracles for our health?</p> <h2>The benefits of olive oil</h2> <p>There’s no doubt that olive oil is full of good stuff. It’s high in polyphenols and antioxidants, which have protective qualities for the body’s tissues. It’s also a rich source of essential fatty acids, including oleic acid, which is known for <a href="https://foodrevolution.org/blog/olives-and-olive-oil-benefits/#:%7E:text=Compared%20with%20olives%2C%20olive%20oil,in%20polyphenols%20and%20antioxidants%2C%20however">lowering cholesterol</a> so reducing the chances of heart disease.</p> <p>Research has found that the inclusion of olive oil in the diet shows encouraging effects in a variety of <a href="https://doi.org/10.3390%2Fnu11092039">inflammatory and medical diseases</a> and can <a href="https://doi.org/10.3389%2Ffnut.2022.980429">support weight management</a> if used correctly.</p> <p>Replacing butter, margarine, mayonnaise and dairy fat with olive oil has been linked to a <a href="https://doi.org/10.1016%2Fj.jacc.2021.10.041">lower risk of mortality</a>. There’s also evidence to suggest that the protective compounds in olive oil may help <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0261649">guard against cancer</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10376491/">dementia</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/29141573/">support the liver</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7916323/">and kidneys</a>.</p> <p>But none of this is new information to health professionals. The health benefits of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7466243/">extra virgin olive oil</a> are <a href="https://doi.org/10.3390%2Fnu11092039">well researched</a> and nutritionists have promoted olive oil as a swap for saturated cooking fat for years.</p> <p>After all, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7536728/">Mediterranean diet</a> has been touted as one of the healthiest diets in the world for decades. The diet itself can vary from region to region, but <a href="https://doi.org/10.3390%2Fnu15092127">virgin olive oil</a> is a <a href="https://doi.org/10.3390%2Fnu11092039">consistent element</a>. It’s used as the <a href="https://www.themediterraneandish.com/cooking-with-olive-oil/">main source of cooking fat</a> and included in everything from salad dressings to bread.</p> <figure><iframe src="https://www.youtube.com/embed/krFcE5IPT7g?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Can fat be healthy? Yes and no</h2> <p>Fats are crucial for a balanced diet, aiding in the absorption of fat-soluble vitamins A,D,E,K and enhancing the nutritional value of meals.</p> <p>However, fat of any kind is also dense in calories and excessive consumption <a href="https://doi.org/10.1159/000336848">can lead to weight gain</a>. According to the <a href="https://www.who.int/news/item/17-07-2023-who-updates-guidelines-on-fats-and-carbohydrates">World Health Organization</a>, to prevent unhealthy weight gain, adults should limit their intake of fat to 30% of total energy intake with no more than 10% coming from saturated fats.</p> <p>Two tablespoons of olive oil – the standard amount in the shots taken by celebrities and social media influencers – contain 28g of fat (238 calories) and 3.8g of saturated fat equating to <a href="https://fdc.nal.usda.gov/fdc-app.html#/food-details/171413/nutrients">19% of the recommended daily intake</a>.</p> <p>That daily shot of extra virgin, then, might not be the best idea. Adding small amounts of olive oil to meals throughout the day is a more balanced – and appetising – approach to incorporating healthy fats into your diet.</p> <p>But what about Kourtney Kardashian’s <a href="https://poosh.com/why-kourtney-kardashian-drinks-tablespoon-evoo/#:%7E:text=First%20things%20first%2C%20it's%20recommended,a.m.%20(every%20other%20day).">claim that</a>: “It’s recommended to consume extra virgin olive oil in the morning on an empty stomach so the oil can coat your system and neutralize your stomach walls for optimal benefits?”</p> <p><a href="https://www.oliveoiltimes.com/briefs/consuming-olive-oil-on-an-empty-stomach-health-benefits/91503">Some brands</a> have also echoed the idea that consuming olive oil on an empty stomach offers unique health benefits. But no. There’s no scientific evidence to suggest this is true.</p> <p>For a healthy but more satisfying snack, Kourtney might try including a handful of olives into her daily diet. Olives offer the same rich array of nutrients, including vitamins E, A and K, alongside essential minerals such as iron, calcium, magnesium, potassium and amino acids.</p> <p>Unlike olive oil, olives have the added benefit of a high fibre content. The combination of fat and fibre enhances feelings of satiety, making olives a nutritious addition to the diet.<!-- Below is The Conversation's page counter tag.

Are fish oil supplements as healthy as we think? And is eating fish better?

<p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>Fish oil, which contains omega-3 fatty acids, is promoted for a number of health benefits – from boosting our heart health, protecting our brain from dementia, and easing the symptoms of rheumatoid arthritis.</p> <p>But what exactly are omega-3 fats and what does the evidence say about their benefits for keeping us healthy?</p> <p>And if they <em>are</em> good for us, does eating fish provide the same benefit as supplements?</p> <h2>What are omega-3 fats?</h2> <p>Omega-3 fatty acids are a type of polyunsaturated fatty acid. They are essential to consume in our diet because we can’t make them in our body.</p> <p>Three main types of omega-3 fats are important in our diet:</p> <ul> <li> <p>alpha-linolenic acid (ALA), which is found in plant foods such as green leafy vegetables, walnuts, flaxseed and chia seeds</p> </li> <li> <p>eicosapentanoic acid (EPA), which is only found in seafood, eggs (higher in free-range rather than cage eggs) and breast milk</p> </li> <li> <p>docosahexaenoic acid (DHA) is also only found in seafood, eggs (again, higher in free-range eggs) and breast milk.</p> </li> </ul> <p>Omega 3s are key to the structure of our cells, and help keep our heart, lungs, blood vessels, and immune system working.</p> <h2>Eating fish vs taking a supplement</h2> <p>The initial studies suggesting omega-3 fats may have health benefits came from <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/j.0954-6820.1976.tb08198.x">observational studies on people eating fish</a>, not from fish oil.</p> <p>So are the “active ingredients” from supplements – the EPA and DHA – absorbed into our body in the same way as fish?</p> <p>An <a href="https://www.sciencedirect.com/science/article/pii/S0002916523281484">intervention study</a> (where one group was given fish and one group fish oil supplements) found the levels of EPA and DHA in your body increase in a similar way when you consume equal amounts of them from either fish or fish oil.</p> <p>But this assumes it is just the omega-3 fats that provide health benefits. There are other <a href="https://www.foodstandards.gov.au/science/monitoringnutrients/afcd/pages/default.aspx">components of fish</a>, such as protein, vitamins A and D, iodine, and selenium that could be wholly or jointly responsible for the health benefits.</p> <p>The health benefits seen may also be partially due to the absence of certain nutrients that would have otherwise been consumed from other types of meat (red meat and processed meat) such as saturated fats and salt.</p> <h2>So what are the benefits of omega 3 fats? And does the source matter?</h2> <p>Let’s consider the evidence for heart disease, arthritis and dementia.</p> <p><strong>Heart disease</strong></p> <p>For cardiovascular disease (heart attacks and stroke), a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD003177.pub3/full">meta-analysis</a>, which provides the highest quality evidence, has shown fish oil supplementation probably makes little or no difference.</p> <p>Another <a href="https://www.mdpi.com/2072-6643/12/8/2278">meta-analysis</a> found for every 20 grams per day of fish consumed it reduced the risk of coronary heart disease by 4%.</p> <p>The <a href="https://www.heartfoundation.org.au/getmedia/f1d22267-7381-4513-834b-df317bed9a40/Nutrition_Position_Statement_-_DIETARY_FAT_FINAL-4.pdf">National Heart Foundation</a> recommends, based on the scientific evidence, eating fish rich in omega-3 fats for optimal heart health. <a href="https://apjcn.nhri.org.tw/server/APJCN/17/3/385.pdf">Fish vary in their omega-3 levels</a> and generally the fishier they taste the more omega-3 fats they have – such as tuna, salmon, deep sea perch, trevally, mackeral and snook.</p> <p>The foundation says fish oil may be beneficial for people with heart failure or high triglycerides, a type of fat that circulates in the blood that increases the risk of heart disease and stroke. But it doesn’t recommend fish oil for reducing the risk of cardiovascular diseases (heart attack and stroke).</p> <p><strong>Arthritis</strong></p> <p>For rheumatoid arthritis, <a href="https://arthritis-research.biomedcentral.com/articles/10.1186/s13075-022-02781-2">studies</a> have shown fish oil supplements do provide benefits in reducing the severity and the progression of the disease.</p> <p>Eating fish also leads to these improvements, but as the level of EPA and DHA needed is high, often it’s difficult and expensive to consume that amount from fish alone.</p> <p><a href="https://arthritisaustralia.com.au/managing-arthritis/living-with-arthritis/complementary-treatments-and-therapies/fish-oils/">Arthritis Australia</a> recommends, based on the evidence, about 2.7 grams of EPA and DHA a day to reduce joint inflammation. Most supplements contain about 300-400mg of omega-3 fats.</p> <p>So depending on how much EPA and DHA is in each capsule, you may need nine to 14 capsules (or five to seven capsules of fish oil concentrate) a day. This is about 130g-140g of grilled salmon or mackeral, or 350g of canned tuna in brine (almost four small tins).</p> <p><strong>Dementia</strong></p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0952327807001421?via%3Dihub">Epidemiological studies</a> have shown a positive link between an increased DHA intake (from diet) and a lower risk of developing Alzheimer’s disease, a type of dementia.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0952327807001421?via%3Dihub">Animal studies</a> have shown DHA can alter markers that are used to assess brain function (such as accumulation of amyloid – a protein thought to be linked to dementia, and damage to tau protein, which helps stabilise nerve cells in the brain). But this hasn’t been shown in humans yet.</p> <p>A systematic review of <a href="http://betamedarts.gr/wp-content/uploads/2021/05/31Psychiatriki03_2020.pdf#page=58">multiple studies in people</a> has shown different results for omega-3 fats from supplements.</p> <p>In the two studies that gave omega-3 fats as supplements to people with dementia, there was no improvement. But when given to people with mild cognitive impairment, a condition associated with increased risk of progressing to dementia, there was an improvement.</p> <p>Another <a href="https://pubmed.ncbi.nlm.nih.gov/25446949/">meta-anlayses</a> (a study of studies) showed a higher intake of fish was linked to lower risk of Alzheimers, but this relationship was not observed with total dietary intake of omega-3 fats. This indicates there may be other protective benefits derived from eating fish.</p> <p>In line with the evidence, the <a href="https://www.alzheimers.org.uk/about-dementia/risk-factors-and-prevention/omega-3-and-dementia#:%7E:text=This%20could%20suggest%20that%20taking,its%20own%20may%20not%20be.">Alzheimer’s Society</a> recommends eating fish over taking fish oil supplements.</p> <h2>So what’s the bottom line?</h2> <p>The more people stick to a healthy, plant-based diet with fish and minimal intakes of ultra-processed foods, the better their health will be.</p> <p>At the moment, the evidence suggests fish oil is beneficial for rheumatoid arthritis, particularly if people find it difficult to eat large amounts of fish.</p> <p>For dementia and heart disease, it’s best to try to eat your omega-3 fats from your diet. While plant foods contain ALA, this will not be as efficient as increasing EPA and DHA levels in your body by eating seafood.</p> <p>Like any product that sits on the shop shelves, check the use-by date of the fish oil and make sure you will be able to consume it all by then. The chemical structure of EPA and DHA makes <a href="https://www.sciencedirect.com/science/article/pii/S0924224421005422">it susceptible to degradation</a>, which affects its nutritional value. Store it in cold conditions, preferably in the fridge, away from light.</p> <p>Fish oil can have some annoying side effects, such as fishy burps, but generally there are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3664575/">minimal serious side effects</a>. However, it’s important to discuss taking fish oil with all your treating doctors, particularly if you’re on other medication.<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/212250/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, Program Director of Nutrition and Food Sciences, Accredited Practising Dietitian, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Essential money conversations retirees should have with family

<p>Discussions about funding retirement, aged care and inheritances may be uncomfortable. However, not having them risks your wishes going unmet and family conflicts where details aren’t clear. </p> <p>Hence having discussions about money while you are able to is one of the best (and cheapest!) investments you can make – for both you and your family.</p> <p>Precisely what those discussions entail will depend on your circumstances – and theirs. Yet many points apply almost universally:</p> <p><strong>What matters to you</strong></p> <p>Even the best laid plans mean nothing if those responsible for enacting them don’t know what they are or understand your reasoning behind them.</p> <p>Your will provides a legal overview of who gets what upon your death, while nominated beneficiaries determine how assets are divided from superannuation and some other structures.</p> <p>A separate letter of wishes can informally share your wishes, covering more than just legalities. Sharing this before your death allows family to clarify your wishes and ask questions. </p> <p><em>Go through:</em></p> <ul> <li>How your money should be managed now and longer term (e.g., you may want money set aside for grandchildren’s education, or have instructions for a dependent’s ongoing care).</li> <li>Funeral arrangements; cremation or burial; where you will be laid to rest.</li> <li>Plans for anyone other than direct family, charities etc.</li> <li>Any non-negotiables among your wishes.</li> </ul> <p><strong>Partner protections</strong></p> <p>Ensure your partner knows how they will be looked after if they outlive you. Similarly, your kids should know what if any support they will need to provide – especially important for blended families. </p> <p>Where beneficiaries have divorced/separated, will you exclude their ex from your estate? Are your records updated to reflect this?</p> <p>Ensure everyone knows the difference between joint tenants and tenants in common for property owners – only one automatically leaves your share of the property to your co-owner. </p> <p><strong>Health matters</strong></p> <p>How do you want to be looked after in your final years? Don’t assume your loved ones already know everything.</p> <p>Communicate your wishes, small and large – medications, dietary requirements, retirement living, palliative care, resuscitation.</p> <p>Discuss whether power of attorney and enduring guardianship are needed should you be unable to make decisions over your health and finances (e.g., due to dementia or stroke), and who will assume those responsibilities.</p> <p><strong>Family legacy</strong></p> <p>Consider the legacy you want to leave and whether this aligns with your family’s expectations.</p> <p>Is dividing assets equally among your children really fair if one is well-off while another struggles or has complex needs? </p> <p>Do your plans on inheritance unwittingly create headaches for the recipients – such as leaving property to someone who cannot afford to maintain it, or tax liabilities that eat into any financial gain?</p> <p>Discuss non-financial legacy too: do your offspring know about your (and hence their) heritage? Are there special family mementos/stories to pass on? This knowledge may be lost if you don’t share it now.</p> <p><strong>Place to call home</strong></p> <p>Given their financial, logistical, and emotional implications, living arrangements are crucial to discuss before things need to change (and change can be imposed suddenly, such as by a health emergency). </p> <p><em>Consider:</em></p> <ul> <li>Where would you want to go if you need high-level care?</li> <li>Is your current home suitable in your advanced years? How would any required modifications be paid for?</li> <li>Would you move nearer your kids? Downsize, upsize or sea/treechange?</li> <li>If you move, would you need to sell your current home? Could it be retained somehow?</li> <li>Do you want/expect kids to care for you? Are they capable of doing so? </li> <li>Could/would you live with one of your children? If so – such as paying to build a granny flat on their property – how does this affect your will? Would they be forced to sell so their siblings receive their inheritance?</li> </ul> <p><strong>Team united</strong></p> <p>Having everyone on the same page helps things to run smoothly – especially during difficult times such as a death or serious illness in the family.</p> <p><em>Stay aligned by:</em></p> <ul> <li>Introducing adult children to your financial adviser, lawyer, and accountant.</li> <li>Ensuring everyone knows where to find your will and who is your executor.</li> <li>Disclosing what is and is not up to date.</li> <li>Providing contingency access to passwords, important documents, keys etc.</li> <li>Sharing relevant policy details (e.g., life insurance).</li> </ul> <p>These discussions may be sensitive and difficult to initiate, but are crucial to ensure your wishes are known and enacted. Plus, they may encourage your loved ones to think about their own wishes – and give you all peace of mind for the future!</p> <p><strong><em>Helen Baker is a licensed Australian financial adviser and author of the new book, On Your Own Two Feet: The Essential Guide to Financial Independence for all Women (Ventura Press, $32.99). Helen is among the 1% of financial planners who hold a master’s degree in the field.

6 essential tips and tricks for your kitchen

<p>Whether you’re friends with a professional chef, watch every cooking show on which you can lay your eyeballs, or your mum was some kind of wise, kitchen magician, it seems that everyone has their very own secret cooking tips to make life easier, or at least less stressful, in the kitchen. We’ve gathered a few of our own just in case no one’s ever shared them with you until now.</p> <p><strong>1. Where there’s smoke…</strong></p> <p>People often think that setting off the smoke detectors is a sign of an unskilled cook, but, as long as you’re not burning anything, don’t be afraid of a little smoke or vapour. Some foods just need that extra heat to reach their flavourful best, and that’s okay. Just make sure you’re safe.</p> <p><strong>2. Dressing in a jar</strong></p> <p>If you’re not a fan of off-the-shelf salad dressings, the natural solution to lifeless salads is making your own dressing. The annoying part of that is mixing such small quantities of ingredients in a bowl can be ridiculously fiddly. Next time, pop those ingredients into an old (clean) jam jar and give it a good shake. Not only will it be easier, you’re guaranteed to combine everything much better than you could with any whisk.</p> <p><strong>3. When life gives you lemons</strong></p> <p>If you’re using lemons or limes when you’re cooking, save the leftover skins once you’ve juiced them. You can use them to disinfect your chopping board without any chemicals. Plus, the smell is pretty fantastic.</p> <p><strong>4. Perfect pasta</strong></p> <p>When cooking pasta, the best tip we can offer is to remove the noodles from their water just before they’re completely cooked. Then, with just a little bit of the starchy water, pour them into the same saucepan in which you’re cooking your sauce. Cooking the pasta with the sauce for at least a minute or two will help infuse the flavours. If you’re not already cooking your pasta this way, you soon will be.</p> <p><strong>5. You crack me up</strong></p> <p>If you find that you’re constantly picking tiny shards of eggshell out of your dishes before you cook, you might want to adjust the way you crack your eggs. Rapping the eggs onto a sharp/thin edge of a bowl of counter causes these small fractures. If you crack the egg onto a flat surface, you’ll avoid a lot of the fuss. Plus, it’s really easy to do that cool one-handed egg crack this way. Bonus!</p> <p><strong>6. No-stick cheese</strong></p> <p>There’s a reason buying pre-grated cheese is so ridiculously expensive – grating cheese yourself is one of the most loathed kitchen tasks around. But if you spray your grater with a little cooking spray before you start, it will help the cheese glide over a little easier. Plus it’s going to make cleaning a dream.</p> <p><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;"><em>Images: Getty</em>                                                                </span></p>

5 essential tips for buying clothes online

<p>It all seems so easy – a few clicks and you can have a pretty pile of clothes (or shoes, bags, jewellery – anything you like really) delivered to your door.</p> <p>But if you’ve ever gotten a bit click-happy with your online shop and then had buyer’s remorse, read on. We’ve got some advice that will ensure you’re left with nothing but five-star reviews for the items you purchased.</p> <p><strong>1. Buy from stores you trust</strong></p> <p>Often we are left dissatisfied when we buy clothes from a brand we don’t know. The fit isn’t quite right, or the quality might be off. Try to point your credit card at labels that you know and love. You’ll know your true size, you’ll know how well the clothes stay in shape after ten washes, and you’ll know you can return it with no hassles.</p> <p><strong>2. Check your wardrobe</strong></p> <p>Often we are attracted to clothes that we think we love, but it turns out we already own something pretty similar. This could explain why you might have five blue and white striped tops (and so perhaps you don’t need another?). Think about whether the items you want to buy fit into your current collection. If you’re buying shorts, do you have some shirts to go with them? If you have your eye on a dress, do your sandals go with it?</p> <p><strong>3. Check the returns policy</strong></p> <p>Many online shopping hubs offer free returns – but it always pays to check the details. Some will only offer store credit, while others offer your money back (no question asked). You’ll also want to be sure that you can either return the items in the post (without paying for postage), or that you can pop in-store to get a refund in person. Don’t get stuck with a bag full of ill-fitting clothes that you can’t easily give back.</p> <p><strong>4. Look for discounts first</strong></p> <p>Many sites offer discounts online, but you have to know where to look to find them. Simply search online for the store name and the word ‘discount coupon’ and you should find a few options to try. Or if you want to save time, download the Honey app, which automatically applies any working coupon available on the web. Then just enjoy the savings.</p> <p><strong>5. Sign up to be notified about sales</strong></p> <p>If there is a brand or site you use often, sign up to the newsletter so that you’re in the loop about big discount sales. Often there are change of season sales, pre- and post-Christmas offers, and more. Stay in the know and plan your splurges accordingly, rather than buying now and then seeing everything half price the following week.</p> <p><em>Image credits: Getty Images</em></p>

Lumps, bumps and oil slicks: what your skin is really trying to tell you

<p>It is common knowledge to drink water, cleanse, tone and moisture to ensure your skin is healthy, but sometimes these methods aren’t enough. Skincare expert and touch therapist, Sarah Jones, believes that skincare starts from the inside and her approach is based around the idea that your skin reflects the tensions and emotions in your life.</p> <p>“Have you ever noticed that your skin reacts badly when you’re under stress? I can sometimes point to a spot and say, 'This is from that terrible traffic jam I got stuck in yesterday.' Or when you’re giddy with good news, people often comment on your skin, saying you’re “glowing”. Don’t underestimate how emotions play a huge role in how our skin behaves,” Sarah said.</p> <p>Sarah explains the emotions behind common skin complaints.</p> <p><strong>Dry skin</strong></p> <p>Sarah suggests that dry skin can be linked to deep-rooted stress, self-criticism and a little sadness. This is common in those who are caring and help others but tend to forget to look after themselves. Be sure to look after yourself even if it is escaping to have a bath, and if you need to talk to someone, speak to a trusted friend or counsellor.</p> <p><strong>Cold sores and breakouts</strong></p> <p>Both of these skin problems can be an indication of unexpressed anger. Sarah explains that cold sores and spots are nature’s way of communicating that you have gotten off balance.</p> <p><strong>Eczema</strong></p> <p>Eczema, which causes crusting and red patches on the skin, is tedious to treat and can be a real battle to overcome. Sarah believes eczema can be a signal that you feel suffocated in your thoughts and emotionally overwhelmed. She suggests writing down how you feel and finding ways to tackle each emotion.</p> <p><strong>Oily skin and acne</strong></p> <p>Those who have oily skin are prone to large pores and regular but small breakouts. Sarah suggests that this can be a sign that you are not relaxed and you put a lot of pressure on yourself. You may also be prone to highly critiquing yourself. Be sure to focus on your confidence and surround yourself with people who encourage you.</p> <p><em>Images: Getty</em></p>

Drugs – 4 essential reads on how they’re made, how they work and how context can make poison a medicine

<p>Pandemics and disease outbreaks put a spotlight on the hurdles researchers face to get a drug on the shelves. From finding prospective drug candidates to balancing time and financial pressures with ensuring safety and efficacy, there are many aspects of drug development that determine whether a treatment ever makes it out of the lab.</p> <p>Broadening the definition of “medicine” and where it can be found, however, could help expand the therapeutic options available for both researchers and patients.</p> <p>Here are four facets of how drugs are developed and how they work in the body, drawn from stories in The Conversation’s archive.</p> <h2>1. Matching drug to target</h2> <p>The most effective drugs are, in a sense, the product of good matchmaking – they bind to a specific disease-causing receptor in the body, elicit a desired effect and ideally ignore healthy parts of the body.</p> <p>Drugs <a href="https://theconversation.com/how-do-drugs-know-where-to-go-in-the-body-a-pharmaceutical-scientist-explains-why-some-medications-are-swallowed-while-others-are-injected-182488" target="_blank" rel="noopener">travel through the bloodstream</a> to reach their targets. Because of this, most drugs circulate throughout the body and can bind to unintended sites, potentially causing undesired side effects.</p> <p>Researchers can increase the precision and effectiveness of a drug by designing different ways to take it. An inhaler, for example, delivers a drug directly to the lungs without its having to travel through the rest of the body to get there.</p> <p>Whether patients take drugs as prescribed is also essential to ensuring the right dose gets to where it needs to be often enough to have a desired effect. “Even with all the science that goes into understanding a disease well enough to develop an effective drug, it is often up to the patient to make it all work as designed,” writes pharmaceutical scientist <a href="https://www.researchgate.net/profile/Thomas-Anchordoquy" target="_blank" rel="noopener">Tom Anchordoquy</a> of the University of Colorado Anschutz.</p> <h2>2. Searching for drug candidates</h2> <p>Researchers have discovered a number of drugs by chance, including <a href="https://www.pbs.org/newshour/health/the-real-story-behind-the-worlds-first-antibiotic" target="_blank" rel="noopener">penicillin</a> for bacterial infections, <a href="https://www.bbc.com/future/article/20200928-how-the-first-vaccine-was-born" target="_blank" rel="noopener">vaccines for smallpox</a> and <a href="https://doi.org/10.1038/nrcardio.2017.172" target="_blank" rel="noopener">warfarin</a> for blood clots. While serendipity still plays a role in modern drug discovery, most drug developers take a systematic approach.</p> <p>Scientists typically start by identifying a particular molecular target, usually receptors that trigger a specific response in the body. Then, they look for chemical compounds that react with that target. Technology called <a href="https://theconversation.com/discovering-new-drugs-is-a-long-and-expensive-process-chemical-compounds-that-dupe-screening-tools-make-it-even-harder-175972" target="_blank" rel="noopener">high-throughput screening</a> allows researchers to quickly test thousands of potential drug candidates at once. Compounds that match screening criteria advance to further development and refinement. Once optimized for their intended use, compounds go on to safety and efficacy testing in animals and people.</p> <p>One way to ease the search for optimal drug candidates is to work with compounds that are already optimized to work in living beings. <a href="https://theconversation.com/nature-is-the-worlds-original-pharmacy-returning-to-medicines-roots-could-help-fill-drug-discovery-gaps-176963" target="_blank" rel="noopener">Natural products</a>, derived from organisms like microbes, fungi, plants and animals, share similar structures and functions across species. Though not without their own development challenges, they could aid the search for related compounds that work in people.</p> <p>“There are thousands of microorganisms in the ocean left to explore as potential sources of drug candidates, not to mention all the ones on land,” writes medical chemist <a href="https://scholar.google.com/citations?user=8_T1ueYAAAAJ&amp;hl=en" target="_blank" rel="noopener">Ashu Tripathi</a> of the University of Michigan. “In the search for new drugs to combat antibiotic resistance, natural products may still be the way to go.”</p> <h2>3. A drug by any other name may be just as effective</h2> <p>Existing drugs can find a second (or third, fourth and fifth) life through repurposing.</p> <p>Most drugs <a href="https://theconversation.com/many-medications-affect-more-than-one-target-in-the-body-some-drug-designers-are-embracing-the-side-effects-that-had-been-seen-as-a-drawback-184922" target="_blank" rel="noopener">have many functions</a> beyond what researchers originally designed them to do. While this multifunctionality is often the cause of unwanted side effects, sometimes these results are exactly what’s needed to treat a completely unrelated condition.</p> <p>Sildenafil, for example, failed to treat severe chest pain from coronary artery disease, but proved to be potent at inducing erections as Viagra. Similarly, thalidomide, a compound that caused birth defects in thousands of infants around the world as a morning sickness drug, found redemption as a cancer treatment.</p> <p>Because drugs inherently have more than one function in the body, <a href="https://theconversation.com/repurposing-generic-drugs-can-reduce-time-and-cost-to-develop-new-treatments-but-low-profitability-remains-a-barrier-174874" target="_blank" rel="noopener">repurposing existing drugs</a> can help fill a gap where pharmaceutical companies and other developers cannot or will not. <a href="https://scholar.google.com/citations?user=iDKZaA4AAAAJ&amp;hl=en" target="_blank" rel="noopener">Gregory Way</a>, a researcher at the University of Colorado Anschutz, uses artificial intelligence to predict the various effects a drug can have and believes that this lack of specificity is something to explore rather than eliminate. Instead of trying to home in on one specific target, he suggests that scientists “embrace the complexity of biology and try to leverage the multifaceted effects drugs can offer.”</p> <h2>4. Poison as medicine</h2> <p>If so many drugs can have toxic effects in the body, be it through side effects or taking the wrong dose or for the wrong condition, what determines whether a drug is a “medicine” or a “poison”?</p> <p>Biomedical scientists evaluate drugs based on their active ingredient, or a specific compound that has a specific effect in the body. But reducing medicines to just a single molecule ignores another important factor that determines whether a drug is therapeutic – the context in which it is used. Opioids treat intractable pain but can lead to debilitating and lethal addiction when improperly administered. Chemotherapy kills tumors but causes collateral damage to healthy tissues in the process.</p> <p>Another pharmaceutical paradigm, <a href="https://theconversation.com/poison-or-cure-traditional-chinese-medicine-shows-that-context-can-make-all-the-difference-163337" target="_blank" rel="noopener">traditional Chinese medicine</a>, has historically acknowledged the malleability of drugs through the use of poisons as therapeutics.</p> <p><a href="https://scholar.google.com/citations?user=4q0hYSwAAAAJ&amp;hl=en" target="_blank" rel="noopener">Yan Liu</a>, a medical historian at University of Buffalo who studies this practice, notes that ancient texts did not distinguish between poisons and nonpoisons – rather, Chinese doctors examined drugs based on a continuum of potency, or ability to harm and heal. They used different processing and administration techniques to adjust the potency of poisons. They also took a personalized approach to treatment, aware that each drug works differently based on a number of different individual factors.</p> <p>“The paradox of healing with poisons in traditional Chinese medicine reveals a key message: There is no essential, absolute or unchanging core that characterizes a medicine,” Liu writes. “Instead, the effect of any given drug is always relational – it is contingent on how the drug is used, how it interacts with a particular body and its intended effects.”</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/drugs-4-essential-reads-on-how-theyre-made-how-they-work-and-how-context-can-make-poison-a-medicine-192590" target="_blank" rel="noopener">The Conversation</a> and is a roundup of of articles from The Conversation’s archives.</strong></p> <p><em>Image: Shutterstock</em></p>

<p dir="ltr">As the season’s transition from winter to summer, there’s no better time to have a wardrobe clear out. </p> <p dir="ltr">While many people like to top up their closet with the latest trends, patterns, colours and fits, it’s important to hold on to classic pieces that never go out of style. </p> <p dir="ltr">"A timeless piece is one that transcends trends and seasons, something that stands the test of time," Jye Marshall, board member of the Australian Fashion Innovation, told <a href="https://style.nine.com.au/latest/five-wardrobe-staples-that-never-go-out-of-style/a07a81ff-38d4-4524-827f-9816c0aee809">9Honey</a>.</p> <p dir="ltr">"It doesn't have to be boring and should reflect your own personal style and celebrate your individuality. Whether it's an edgy cut or a vintage collection – it really depends on what brings you the most fashion joy."</p> <p dir="ltr">Next time you’re looking to purchase clothes, or you’re considering doing a wardrobe clear out, think about investing in these five timeless styles. </p> <p dir="ltr"><strong>Jewellery</strong></p> <p dir="ltr">According to new research from Klarna, almost one third of Aussies consider jewellery to be the most timeless, and most valued, item in their wardrobe.</p> <p dir="ltr">"Jewellery is often passed through a few owners, whether it's a sentimental piece from a family member or something you collected at a vintage store," Marshall says.</p> <p dir="ltr">Even the most basic jewellery can elevate any outfit, so hold on to your valuable pieces as they tend to go with everything. </p> <p dir="ltr"><strong>Blazer</strong></p> <p dir="ltr">A classic blazer is one of the most noteworthy wardrobe must-haves, with 13 percent of Australians considering them the most timeless piece they own. </p> <p dir="ltr">Marshall echoes this sentiment, saying the versatility of the blazer is what makes it such a staple piece.</p> <p dir="ltr">He said, "This is a wardrobe must, with flexibility to dress up or down, smart or casual, work or leisure. The list goes on."</p> <p dir="ltr"><strong>Denim</strong></p> <p dir="ltr">Whether it's a jacket or the perfect pair of jeans, denim is destined to be found in most wardrobes. </p> <p dir="ltr">"Denim has a long history," he says. "It was traditionally made for workwear due to its properties of durability, and therefore makes the perfect staple piece."</p> <p dir="ltr"><strong>Wool fibre garments</strong></p> <p dir="ltr">Good quality knitwear is a must-have for any wardrobe, even though it only gets used for half of the year. </p> <p dir="ltr">Investing in good quality materials instead of synthetic wool will mean your favourite jumper lasts much longer than just one season. </p> <p dir="ltr">"I absolutely love a good quality knit," Marshall says. "Wool fibre garments have a variety of natural properties such as natural anti-wrinkle, anti-odour and it's breathable, these are all the traits I would be looking for in a piece that can be worn from many years to come."</p> <p dir="ltr"><strong>Leather</strong></p> <p dir="ltr">The versatility of leather is utilised by many, whether its a jacket, pants or the ultimate accessories. </p> <p dir="ltr">"Second hand leather garments like jackets or pants that can make great timeless pieces," Marshall says. </p> <p dir="ltr">"I love how great they look brand new and how easily they can be positioned as vintage after you've worn them out!"</p> <p dir="ltr"><em>Image credits: Getty Images</em></p>

6 essential tips for travelling with grandkids

<p>Spending time with the grandkids can be both a rewarding and frustrating experience. While they can be a source of cuddles and homemade artwork, little ones can also bring out the worst in us, leading to family arguments and the testing of even the strongest relationships.</p> <p>So if you are planning a trip with little ones, here’s how to make the most of the opportunity for a family holiday.</p> <p><strong>Get their input</strong></p> <p>Rather than just planning everything out for them, get them to help decide on the itinerary. By getting them involved in the decision making process it makes them feel more of an equal player on the trip. </p> <p>This way they are also less likely to make a fuss when you let them know it’s time to go to the museum now, even when they are having fun in the pool.</p> <p><strong>Lay out the ground rules</strong></p> <p>Let the grandkids know what is going to happen in terms of who pays for what. This could be theme park entries, souvenir purchases, or meals and snacks. This will eliminate issues down the track.</p> <p><strong>Decide on a fair use for electronic devices</strong></p> <p>Though you may not be as obsessed with your smartphone, tablet, gaming console or laptop – your grandchildren might be. Allow them to use their devices for at least a short time each day on your trip, but first check with their parents on the family rules. </p> <p>Feel free to put your own rules in place, such as no devices during meal times. </p> <p><strong>Plan for relaxation time</strong></p> <p>Down time needs to be allowed for each day, as being on the go can be exhausting for both kids and grandparents alike. Build this into your schedule, whether that means naps for little ones, watching movies or just relaxing by the pool.</p> <p><strong>Allow for changes to the plan</strong></p> <p>Don’t be too rigid with your schedule as kids can of course be unpredictable with their moods. If you notice the grandkids are getting tired or emotional it might be a good idea to skip a planned activity in favour of more down time or some time apart. </p> <p>Older children might want to make an unscheduled stop based on a recommendation from someone they meet on the trip. Always take their ideas on board rather than dismissing them, and go for a group consensus if it will affect everyone. </p> <p><strong>Make your own memories</strong></p> <p>Keep in mind that when things go wrong or the weather is bad, this can be an opportunity rather than a disaster. Use these times to talk to the grandkids about times when your travel plans have gone awry and led to a fun or interesting outcome.</p> <p>Purposely take part in activities that you know they will remember as they grow older – it could be trying a fun new food together, sleeping under the stars, trekking up a mountain to watch the sunset, or getting up early to go fishing on the beach together.</p> <p><em>Image credits: Getty Images</em></p>

Three arguments why Just Stop Oil was right to target Van Gogh’s Sunflowers

<p>Waves of controversy were sparked recently when the Just Stop Oil activists <a href="https://edition.cnn.com/style/article/oil-protest-van-gogh-sunflower-soup-intl-scli-gbr/index.html">threw tomato soup</a> over Van Gogh’s Sunflowers at the National Gallery in London. Although the painting was behind glass <a href="https://www.theguardian.com/environment/2022/oct/14/just-stop-oil-activists-throw-soup-at-van-goghs-sunflowers">so not damaged</a>, politicians were quick to condemn their “<a href="https://twitter.com/JamesCleverly/status/1581327788388163584?s=20&amp;t=ACNnBMBQN9UNL-cxoRhrVg">attention-seeking</a>” vandalism while media commentators proclaimed that the act had “<a href="https://twitter.com/AndrewMarr9/status/1580879221656006656?s=20&amp;t=ACNnBMBQN9UNL-cxoRhrVg">lost them</a>” to the cause. </p> <p>It is perhaps with some poetic timing that I’ve just started a project that is an oral history of the <a href="https://www.royalholloway.ac.uk/research-and-teaching/departments-and-schools/geography/oral-history-of-the-environmental-movement-project/">environmental movements in the UK</a>. The aim is to contribute to a greater understanding and wider public awareness of the variety of modes of engagement with environmental issues.</p> <p>This tactic was certainly a provocative act and Van Gogh’s work is undoubtedly some of the most important artwork of modern times. However, many of these commentaries on Just Stop Oil’s actions simply just don’t hold up. </p> <p>The main critiques of the activist stunt are that it <a href="https://www.commondreams.org/news/2022/10/14/just-stop-oils-van-gogh-soup-stunt-sparks-criticism-alienating-strategy">alienates people</a> who are sympathetic to the climate cause by attacking a much-loved and important piece of art. That it smacks of <a href="https://theconversation.com/climate-change-is-too-middle-class-heres-how-to-fix-that-123231">middle-class activism</a> and is overly performative. And, finally, that it has required “<a href="https://currentlyhq.com/personal/we-need-more-climate-protests-just-not-performative-ones/">explanation</a>”, which if you have to do, you’re losing.</p> <p>While there is some truth to these critiques, I don’t buy them.</p> <p>Rather than wade further into the quagmire of social media debate, here is a breakdown of the three arguments and explanations of why I think that this kind of provocative activism deserves our unwavering support.</p> <h2>1. Art is an extension of corporate power</h2> <p>First off, museums and art galleries have long been used by fossil fuel companies for the purposes of <a href="https://www.plutobooks.com/9780745335889/artwash/">artwashing</a> – the ethically acceptable process of funding art and culture to smooth over their very unethical corporate practices. Some of the more conscientious institutions (<a href="https://www.theguardian.com/business/2018/oct/19/shells-ends-national-gallery-sponsorship-to-delight-of-campaigners">including</a> <a href="https://www.ft.com/content/c3ab1b10-ee06-4fac-abe9-1a1e4dcef39f">The National Gallery</a>) have <a href="https://news.artnet.com/art-world/bp-ends-tate-sponsorship-2017-447041#:%7E:text=Tate%20was%20forced%20to%20disclose,year%20between%201990%20and%202006.">cut ties</a>with any sponsorship from oil companies, but others have <a href="https://www.channel4.com/news/revealed-science-museum-signed-gagging-clause-with-exhibition-sponsor-shell">doubled down</a> on it.</p> <p>Art itself, through the <a href="https://qz.com/513625/the-new-reserve-currency-for-the-worlds-rich-is-not-actually-currency/">networks of global trading</a>, <a href="https://www.bloomberg.com/news/articles/2021-11-02/how-do-the-rich-avoid-taxes-billionaires-use-this-art-strategy?leadSource=uverify%20wall">tax avoidance</a> and the creation of <a href="https://mitpress.mit.edu/9783956796227/">freeports</a> (huge walled complexes where art is stored away from prying eyes and tax collectors), has become <a href="https://www.plutobooks.com/9780745338248/art-after-money-money-after-art/">totally intertwined</a> with global corporate and fossil fuel capitalism. Corporations plough money into art institutions and art pieces themselves because it buys them validity in the eyes of the public. Art becomes a shield for their more nefarious planet-destroying practices.</p> <p>But the art should never be considered above, or separate from, the capitalist content behind it. Millions of treasured pieces of art are now under the purview of corporate power and have <a href="https://newrepublic.com/article/147192/modern-art-serves-rich">become windows</a> – beautiful windows no doubt, but still windows – into the shady practices of global capital and <a href="https://www.emerald.com/insight/content/doi/10.1108/JMLC-01-2021-0002/full/html?casa_token=HAd9Kr6jD2kAAAAA:37GtlbaQIbxeoQOtXExK2-OKjvog5kYNaEv94Jwy_MF1ssCHNztVGBofMoPYjqp-NMkKE5PYOPklW_nmDBelpT8QQpgo6cEAmp_vF_Ydv6DNIL8h1Q">international tax avoidance</a>. As hard as it is to stomach sometimes, art pieces, in this way, become extensions of corporate power and hence are legitimate targets of climate activism.</p> <h2>2. Fighting class oppression and climate change is the same</h2> <p>The second critique, often coming from the left, accuses climate activism of being inherently middle-class. Groups, they argue, are populated by white people and the “mess” they create (be that with soup on paintings or <a href="https://twitter.com/Taj_Ali1/status/1581332937475207169?s=20&amp;t=4ELyikRjs5qmUWZuNYYl6g">milk on supermarket floors</a>) is often cleared up by working-class cleaning staff. </p> <p>There is truth in these arguments, which are often missing from the justification of these activist practices. However, taking a more holistic approach, social and economic justice is a fundamental pillar of climate justice – you cannot have <a href="https://www.opendemocracy.net/en/oureconomy/cop26-tackling-climate-breakdown-and-delivering-economic-justice-must-go-hand-in-hand/">one without the other</a>. The Just Stop Oil activists who defaced the Van Gogh recognised these arguments in part when <a href="https://twitter.com/JustStop_Oil/status/1580883249228046336?s=20&amp;t=x0HvtkQci8bXDeUjY0EFQw">they said</a> that many people “can’t afford to even buy and heat soup because of the energy crisis”.</p> <p>“Solving” the climate crisis demands total system change. As <a href="https://theconversation.com/climate-strikes-greta-thunberg-calls-for-system-change-not-climate-change-heres-what-that-could-look-like-112891">Greta Thunberg</a> and other prominent voices have constantly said. Capitalism will not solve the problem, it only makes it worse. Capitalism has the oppression of the working class as its core engine. So, fighting against the changing climate means also fighting capitalism’s class (and indeed, racial, gendered and ableist) imbalance. The two are, and need to continue to be, one.</p> <h2>3. Direct action is important</h2> <p>Finally, some people have wheeled out the phrase “if you’re explaining yourself, you’re losing”. Again, there is a kernel of truth to that, but the severity of the climate catastrophe needs no further explanation. </p> <p>Explaining is not the point of direct action. If you need to be “won over” by the argument, then you’re clearly not doing enough. </p> <p>Just Stop Oil’s action with soup on Sunflowers was to symbolise that we’re attacking something we love. The level of ire at those symbolically ruining – remember, it was behind glass so has not be destroyed – a precious art piece should be given a million-fold to those who are actually ruining our precious planet.</p> <p>Direct climate action will only increase as the situation worsens and our governments continue to actively make things worse with new mines, fracking and new <a href="https://www.theguardian.com/business/2022/oct/07/uk-offers-new-north-sea-oil-and-gas-licences-despite-climate-concerns">oil drilling contracts</a>. <a href="https://www.versobooks.com/books/3665-how-to-blow-up-a-pipeline">Destroying pipelines</a>, <a href="https://www.insider.com/laver-cup-climate-change-activist-sets-his-arm-on-fire-on-court-2022-9">demanding an end to private jets</a> and other direct action against fossil fuel burning infrastructures are important acts in this regard. They highlight how art is also part of that infrastructure and is therefore equally vital.</p> <p>The current crop of climate activists –- Just Stop Oil, Extinction Rebellion, Insulate Britain etc – will forge their own path because that is what activists need to do to make their points heard. But for all the reasons outlined above, understanding the history (and their successes and failures) will be important to help build a coherent, united and effective climate movement. </p> <p>That cohesive movement will need art yes, but not as a conduit for the very capitalist vehicles that are destroying our beautiful planet. As Van Gogh himself said, "…it is not the language of painters but the language of nature which one should listen to, the feeling for the things themselves, for reality is more important than the feeling for pictures."</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/three-arguments-why-just-stop-oil-was-right-to-target-van-goghs-sunflowers-192661" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Achoo! 5 essential reads for pollen season

<p>As spring expands across North America, trees, shrubs and flowers are releasing <a href="https://www.britannica.com/science/pollen">pollen</a>. This fine, powdery substance is produced by the male structures of cone-bearing and flowering plants. When it’s carried to the plants’ female structures by wind, water or pollinators, fertilization happens. </p> <p>As pollen travels, it also triggers allergies in <a href="https://www.aafa.org/allergy-facts/">some 25 million Americans</a>. Pollen exposure can cause sneezing, coughing, itchy eyes, runny nose and postnasal drip – unwelcome signs of spring for sufferers. This roundup of articles from our archives describes recent findings on protecting pollinators and coping with pollen season.</p> <h2>1. Hey pollinators, over here</h2> <p>Since pollen grains carry the cells that fertilize plants, it’s critical for them to get where they need to go. Often wind or gravity is all it takes, but for many plants, a pollinator has to carry the pollen grains. Some plants offer nectar or edible pollen to attract insects, bats or other animals, which carry pollen from plant to plant as they forage. Many flowers also <a href="https://theconversation.com/why-do-flowers-smell-151672">lure pollinators with scent</a>.</p> <p>“Similar to the perfumes at a department store counter, flower scents are made up from a large and diverse number of chemicals which evaporate easily and float through the air,” writes Mississippi State University horticulturalist <a href="https://scholar.google.com/citations?user=dJ8gD7MAAAAJ&amp;hl=en">Richard L. Harkess</a>. “To differentiate itself from other flowers, each species’ flowers put out a unique scent to attract specific pollinators. … Once pollinated, the flower stops producing a floral scent and nectar and redirects its energy to the fertilized embryo that will become the seed.”</p> <h2>2. Bees at the buffet</h2> <p>It’s well known that many species of insects have <a href="https://theconversation.com/insect-apocalypse-not-so-fast-at-least-in-north-america-141107">declined in recent years</a>. One big focus is <a href="https://www.aphis.usda.gov/aphis/ourfocus/planthealth/plant-pest-and-disease-programs/honey-bees/honeybees">honeybees</a> and <a href="https://theconversation.com/beyond-honey-bees-wild-bees-are-also-key-pollinators-and-some-species-are-disappearing-89214">other species of bees</a>, which pollinate many important crops. </p> <p>In a 2021 study, University of Florida agricultural extension specialist <a href="https://scholar.google.com/citations?user=I8IjAnIAAAAJ&amp;hl=en">Hamutahl Cohen</a> found that when bees visited fields where sunflowers, grown as crops, were blooming over many acres, they <a href="https://theconversation.com/planting-mixes-of-flowers-around-farm-fields-helps-keep-bees-healthy-170527">picked up parasites at a high rate</a>. In contrast, bees that foraged in hedgerows around crop fields and could choose from diverse types of flowers to feed on spread out farther and had lower rates of infection.</p> <p>“The more bees in sunflower fields, the more parasites,” Cohen observed. “Sunflower blooms were aggregating bees, which in turn was amplifying disease risk.” However, “in the presence of many flower types, bees disperse and spread across resources, reducing each individual bee’s likelihood of encountering an infected individual.”</p> <h2>3. Warmer weather means more pollen</h2> <p>As climate change raises average temperatures across the U.S., growing seasons are starting earlier and ending later in the year. That’s <a href="https://theconversation.com/pollen-season-is-getting-longer-and-more-intense-with-climate-change-heres-what-allergy-sufferers-can-expect-in-the-future-179158">bad news for allergy sufferers</a>. </p> <p>“The higher temperature will extend the growing season, giving plants more time to emit pollen and reproduce,” write University of Michigan atmospheric scientists <a href="https://clasp.engin.umich.edu/people/zhang-yingxiao/">Yingxiao Zhang</a> and <a href="https://scholar.google.com/citations?user=3dWPwz8AAAAJ&amp;hl=en">Allison L. Steiner</a>. And by increasing the concentration of carbon dioxide in Earth’s atmosphere, climate change will make it possible for plants to grow larger and generate more pollen. </p> <p>“Southeastern regions, including Florida, Georgia and South Carolina, can expect large grass and weed pollen increases in the future. The Pacific Northwest is likely to see peak pollen season a month earlier because of the early pollen season of alder,” Zhang and Steiner report.</p> <h2>4. Providing better forecasts</h2> <p>With all that pollen out there, how can allergy sufferers know when counts are high? Today the U.S. has only a rudimentary network of 90 pollen observation stations across the country, staffed by volunteers and run only during pollen season, so often there isn’t good information available when people need it.</p> <p><a href="https://scholar.google.com/citations?user=sUwveOEAAAAJ&amp;hl=en">Fiona Lo</a>, an environmental health scientist at the University of Washington, is working with colleagues to develop a model that can predict airborne pollen releases. “Our forecast can predict for specific pollen types because our model includes information about how each plant type interacts differently with the environment,” Lo reports.</p> <p>So far, the model only predicts levels of four types of common pollen in areas where there are observation stations. Ultimately, though, Lo and her collaborators “want to provide a forecast every day during pollen season to give allergy sufferers the information they need to manage their symptoms. Allergies are often undertreated, and knowledge about self-care is limited, so a reliable pollen forecast that is easy to access – for example, via an app on your phone – along with education on allergy management, could really help allergy sufferers.”</p> <h2>5. Support pollinators in your garden</h2> <p>Pollen season is also gardening season, since it’s when plants are blooming. West Virginia University mycologist <a href="https://www.researchgate.net/profile/Brian-Lovett">Brian Lovett</a>offers advice for gardeners who want to <a href="https://theconversation.com/to-help-insects-make-them-welcome-in-your-garden-heres-how-153609">attract beneficial insects to their yards</a> for pollination and other purposes. </p> <p>One step is to replace grass with native wildflowers, which will provide pollen and nectar for insects like ants, bees and butterflies. “Just as you may have a favorite local restaurant, insects that live around you have a taste for the flowers that are native to their areas,” Lovett notes.</p> <p>Replacing white lightbulbs with yellow or warm-hued LED bulbs, and providing water in dishes or other containers, are also insect-friendly steps. Local university extension offices and gardening stores can offer other suggestions. </p> <p>“In my view, humans all too often see ourselves as separate from nature, which leads us to relegate biodiversity to designated parks,” Lovett observes. “In fact, however, we are an important part of the natural world, and we need insects just as much as they need us.”</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/achoo-5-essential-reads-for-pollen-season-181672" target="_blank" rel="noopener">The Conversation</a>. </em></p>

4 essential reads on pesticides and the environment

<p>In 1962 environmental scientist Rachel Carson published “<a href="http://www.rachelcarson.org/SilentSpring.aspx" target="_blank" rel="noopener">Silent Spring</a>,” a bestselling book that asserted that overuse of pesticides was harming the environment and threatening human health. Carson did not call for banning DDT, the most widely used pesticide at that time, but she argued for using it and similar products much more selectively and paying attention to their effects on nontargeted species.</p> <p>“Silent Spring” is widely viewed as <a href="https://www.nytimes.com/2012/09/23/magazine/how-silent-spring-ignited-the-environmental-movement.html" target="_blank" rel="noopener">an inspiration for the modern environmental movement</a>. These articles from The Conversation’s archive spotlight ongoing questions about pesticides and their effects.</p> <h2>1. Against absolutes</h2> <p>Although the chemical industry attacked “Silent Spring” as <a href="https://www.penguinrandomhouse.com/books/170448/on-a-farther-shore-by-william-souder/" target="_blank" rel="noopener">anti-science and anti-progress</a>, Carson believed that chemicals had their place in agriculture. She “favored <a href="https://theconversation.com/would-rachel-carson-eat-organic-94967" target="_blank" rel="noopener">a restrained use of pesticides, but not a complete elimination</a>, and did not oppose judicious use of manufactured fertilizers,” writes Harvard University sustainability scholar <a href="https://wcfia.harvard.edu/people/robert-l-paarlberg" target="_blank" rel="noopener">Robert Paarlberg</a>.</p> <p>This approach put Carson at odds with the fledgling organic movement, which totally rejected synthetic pesticides and fertilizers. Early organic advocates claimed Carson as a supporter nonetheless, but Carson kept them at arm’s length. “The organic farming movement was suspect in Carson’s eyes because most of its early leaders were not scientists,” Paarlberg observes.</p> <p>This divergence has echoes today in debates about whether organic production or steady improvements in conventional farming have more potential to feed a growing world population.</p> <h2>2. Concerned cropdusters</h2> <p>Well before “Silent Spring” was published, a crop-dusting industry developed on the Great Plains in the years after World War II to apply newly commercialized pesticides. “Chemical companies made broad promises about these ‘miracle’ products, with little discussion of risks. But pilots and scientists took <a href="https://theconversation.com/farmers-and-cropdusting-pilots-on-the-great-plains-worried-about-pesticide-risks-before-silent-spring-91976" target="_blank" rel="noopener">a much more cautious approach</a>,” recounts University of Nebraska-Kearney historian <a href="https://scholar.google.com/citations?user=37kbK3MAAAAJ&amp;hl=en" target="_blank" rel="noopener">David Vail</a>.</p> <p>As Vail’s research shows, many crop-dusting pilots and university agricultural scientists were well aware of how little they knew about how these new tools actually worked. They attended conferences, debated practices for applying pesticides and organized flight schools that taught agricultural science along with spraying techniques. When “Silent Spring” was published, many of these practitioners pushed back, arguing that they had developed strategies for managing pesticide risks.</p> <p>Today aerial spraying is still practiced on the Great Plains, but it’s also clear that insects and weeds rapidly evolve resistance to every new generation of pesticides, trapping farmers on what Vail calls “a chemical-pest treadmill.” Carson anticipated this effect in “Silent Spring,” and called for more research into alternative pest control methods – an approach that <a href="https://www.usda.gov/oce/pest/integrated-pest-management" target="_blank" rel="noopener">has become mainstream today</a>.</p> <h2>3. The osprey’s crash and recovery</h2> <p>In “Silent Spring,” Carson described in detail how chlorinated hydrocarbon pesticides persisted in the environment long after they were sprayed, rising through the food chain and building up in the bodies of predators. Populations of fish-eating <a href="https://raptor.umn.edu/about-raptors/learn-about-raptors" target="_blank" rel="noopener">raptors</a>, such as bald eagles and ospreys, were ravaged by these chemicals, which thinned the shells of the birds’ eggs so that they broke in the nest before they could hatch.</p> <p>“Up to 1950, ospreys were one of the most widespread and abundant hawks in North America,” writes Cornell University research associate <a href="https://academy.allaboutbirds.org/person/alan-poole/" target="_blank" rel="noopener">Alan Poole</a>. “By the mid-1960s, the number of ospreys breeding along the Atlantic coast between New York City and Boston <a href="https://theconversation.com/ospreys-recovery-from-pollution-and-shooting-is-a-global-conservation-success-story-111907" target="_blank" rel="noopener">had fallen by 90%</a>.”</p> <p>Bans on DDT and other highly persistent pesticides opened the door to recovery. But by the 1970s, many former osprey nesting sites had been developed. To compensate, concerned naturalists built nesting poles along shorelines. Ospreys also learned to colonize light posts, cell towers and other human-made structures.</p> <p>Today, “Along the shores of the Chesapeake Bay, nearly 20,000 ospreys now arrive to nest each spring – the largest concentration of breeding pairs in the world. Two-thirds of them nest on buoys and channel markers maintained by the U.S. Coast Guard, who have become de facto osprey guardians,” writes Poole. “To have robust numbers of this species back again is a reward for all who value wild animals, and a reminder of how nature can rebound if we address the key threats.”</p> <h2>4. New concerns</h2> <p>Pesticide application techniques have become much more targeted in the 60 years since “Silent Spring” was published. One prominent example: crop seeds coated with neonicotinoids, the world’s most widely used class of insecticides. Coating the seeds makes it possible to introduce pesticides into the environment at the point where they are needed, without spraying a drop.</p> <p>But a growing body of research indicates that even though coated seeds are highly targeted, much of their pesticide load washes off into nearby streams and lakes. “Studies show that neonicotinoids are <a href="https://theconversation.com/farmers-are-overusing-insecticide-coated-seeds-with-mounting-harmful-effects-on-nature-176109" target="_blank" rel="noopener">poisoning and killing aquatic invertebrates</a> that are vital food sources for fish, birds and other wildlife,” writes Penn State entomologist <a href="https://scholar.google.com/citations?user=AAdZM1UAAAAJ&amp;hl=en" target="_blank" rel="noopener">John Tooker</a>.</p> <p>In multiple studies, Tooker and colleagues have found that using coated seeds reduces populations of beneficial insects that prey on crop-destroying pests like slugs.</p> <p>“As I see it, neonicotinoids can provide good value in controlling critical pest species, particularly in vegetable and fruit production, and managing invasive species like the spotted lanternfly. However, I believe the time has come to rein in their use as seed coatings in field crops like corn and soybeans, where they are providing little benefit and where the scale of their use is causing the most critical environmental problems,” Tooker writes.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/silent-spring-60-years-on-4-essential-reads-on-pesticides-and-the-environment-192232" target="_blank" rel="noopener">The Conversation</a>. </strong></p> <p><em>Image: Shutterstock</em></p>

"An essential piece in every wardrobe": Young people are shopping for luxury like never before

<p>I recently purchased a pair of sandals. Not just any sandals, but an $850 pair of sandals. They are neatly stitched from calfskin leather, an “<a href="https://www.hermes.com/ca/en/product/izmir-sandal-H041141ZH01400/">essential piece in every wardrobe</a>,” or so I’ve been told. </p> <p>The absurdity of this is not lost on me. But I, like so many young people my age, want to keep up and stay in-step with the city’s sartorial styles and the fashionable people who wear them. </p> <p>In our visual and virtual culture, visions and dreams of fashionable people and the luxurious things they purchase are constantly up for show. Young people know this well. They are repeatedly invited to follow, and “like,” lives and lifestyles once kept hidden by the well-to-do. </p> <p>A look to Instagram’s Discover page or TikTok’s For You page, provides a window into “rich kids” and “<a href="https://doi.org/10.1093/ccc/tcab033">luxury fashion hauls</a>” as well as critical commentary on the season’s latest staples and the “new” versus “old” money looks they <a href="https://www.tiktok.com/@eileen_darling/video/6977003418619497734">might lend themselves to</a>. </p> <p>Together, content of this kind plays an important part in fostering a sense of aspiration and desire, in stoking anxiety about who we are and, what we should buy.</p> <p>It may come as little surprise that, following <a href="https://www.mckinsey.com/featured-insights/coronavirus-leading-through-the-crisis/charting-the-path-to-the-next-normal/fashion-industrys-profits-hemmed-in-by-the-covid-19-pandemic">a downturn in sales driven by the COVID-19 pandemic</a> and media fanfare surrounding “<a href="https://www.nytimes.com/interactive/2020/08/06/magazine/fashion-sweatpants.html">the end of fashion</a>,” luxury products like the sandals I stepped out to buy are <a href="https://news.northeastern.edu/2022/01/26/luxury-spending-surge-during-pandemic/">being sold with great speed</a>. </p> <p>And much or most of these sales are <a href="https://www.businessinsider.com/gucci-millennials-teens-love-designer-comeback-2018-11">driven by consumers under the age of 35</a>, with reporters and scholars documenting a new cohort of young people <a href="https://doi.org/10.1007/978-3-030-01671-5">eager to acquire luxury goods of their own</a>. </p> <p>Some will no doubt make their purchase online where, as sociologist and philosopher Zygmunt Bauman observed, <a href="https://doi.org/10.1177/146954050100100102">our shopping can be “broken up” into dozens of “joyful moments.”</a> Still others will take their business to brick-and-mortar stores where class-based aspirations (and anxieties) take meaningful form. My research looks at how cultural workers like stylists and visual merchandisers <a href="https://doi.org/10.1177/13675494221099578">influence our purchases</a>.</p> <h2>A place for aspiration</h2> <p>Retail giants in the luxury sector like Chanel, Tom Ford and Dior, invest heavily in their brick-and-mortar stores — a physical pronouncement of their brands’ prestige and authority in the fashion landscape. </p> <p>In the past five years, these retailers have taken significant steps to court Millennials and members of Generation Z, with routine invitations to come in and purchase everything from small leather goods and high-end trainers, to micro-bags and belts.</p> <p>These luxury retail environments feel “expensive” and “exclusive,” and this is the result of co-ordinated efforts on behalf of a team of cultural workers who often go without notice. </p> <p>Visual merchandisers, for example, position products and arrange decorative fixtures to produce a vision of beauty and glamour. Sales associates and stylists connect with clients and drive sales in store. </p> <p>I interviewed several cultural workers <a href="https://doi.org/10.1177/13675494221099578">to identify and explain how they do this</a>, how they leverage a series of techniques to foster aspiration, class-based desires and anxieties to command three- and four- figure purchases. </p> <p>They cite current designers and fashion trends, lending knowledge to clients with cash and credit to spend. Stylists also make use of carefully crafted stories related to where clients’ purchases might be worn and what these purchases say about them. Put differently, they romance their clients with visions and dreams of who they could be.</p> <p>All the while, the <a href="http://dx.doi.org/10.12942/lrlr-2009-3">material dimensions of place</a> give stylists and merchandisers authority and what sociologists call “capital.”</p> <p>Pony-hair upholstered furniture, tufted cushions and bronzed mirrors are some of the things that help them produce a sense of awe among clients who in turn, defer to their stylists and their well-furnished fashion knowledge. But they do something more too. These physical and symbolic markers of place remind purchasers that some, but not all are welcome inside. </p> <p>Historian Sarah Miller-Davenport has <a href="https://www.jstor.org/stable/44363357">discussed what it means to feel unwelcome</a> in these settings; to be, as she puts it, a “trespasser, a class-tourist in a rich person’s department store.” </p> <p>For young people, the physical and symbolic markers of these luxury retail environments bear significant weight. They communicate “a sense of one’s place” and suggest the purchaser might be made more fashionable and therefore worthwhile, if and when they purchase luxury products the likes of which we see on celebrities and social media. </p> <p>Of course, there are few of us who can truly afford to make these purchases and fewer still who can make them regularly, leaving many stretched thin and others, in debt to their aspirations and desire.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/an-essential-piece-in-every-wardrobe-young-people-are-shopping-for-luxury-like-never-before-184536" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Sunscreen: here’s why it’s an anti-ageing skincare essential

<p>Every month there seems to be a trendy new product to add to your skincare collection. Lately, a commonplace product that many people already use has taken the top spot, with everyone from dermatologists to influencers swearing by it as the number one way to stay looking youthful through the years: sunscreen.</p> <p>It’s no wonder. It’s thought that solar exposure – also known as “photoageing” – causes up to <a href="https://pubmed.ncbi.nlm.nih.gov/24101874/">80% of skin ageing</a>. So if you’re someone who’s worried about fine lines, wrinkles and uneven pigmentation, limiting the amount of solar radiation you get is one of the most important things you can do.</p> <p>There are thought to be a number of different triggers for photoageing. Most research has linked it to the expression of a group of proteins called matrix metalloproteinases (MMPs). These proteins are enzymes that break down elastins and collagens in the skin’s deeper layer (called the dermis). Elastins and collagens are responsible for the skin’s structure, strength and stretchiness.</p> <p>Expression of these MMP proteins has been linked to both <a href="https://europepmc.org/article/med/18459971">DNA damage</a> in skin cells and the <a href="https://pubmed.ncbi.nlm.nih.gov/19116368/">production</a> of <a href="https://link.springer.com/article/10.1007/BF02505041">reactive oxygen species</a>. Reactive oxygen species are highly reactive chemicals formed from oxygen that can damage other cellular components, such as DNA and proteins.</p> <p>Both of these factors are caused by too much sun exposure. Over time, this damage accumulates to cause characteristic signs of ageing. This may explains why one study even showed people who tended to avoid the sun had <a href="https://pubmed.ncbi.nlm.nih.gov/24101874/">significantly fewer signs of ageing</a> compared to people who enjoyed spending time in the sun.</p> <p>But it isn’t always possible to avoid the sun – which is where sunscreens help. These products contain ingredients (such as zinc oxide) which absorb or reflect UV radiation and dissipate it safely before it can damage our skin cells. This also reduces the cumulative dose of radiation received by the skin.</p> <p>Studies have shown that sunscreens can prevent many signs of photoageing by tackling the triggers, with <a href="https://pubmed.ncbi.nlm.nih.gov/16520862/">numerous studies</a> showing they can prevent the expression of MMPs. A study that compared the effects of <a href="https://pubmed.ncbi.nlm.nih.gov/7490363/">using sunscreen versus a placebo</a> on skin ageing, found that people in the placebo group had higher levels of solar elastosis (a sign of photoageing which causes a loss of elasticity) after two years.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/23732711/">An Australian study</a> compared levels of photoageing in groups assigned to daily sunscreen use versus discretionary sunscreen use. In the daily sunscreen use group, there was no detectable increase in skin ageing over the four-and-a-half year study period compared to the discretionary sunscreen group. <a href="https://pubmed.ncbi.nlm.nih.gov/27749441/">Another study</a> has also shown daily sunscreen use for a year may reverse visible signs of ageing when assessed by a dermatologist.</p> <h2>Choosing the right product</h2> <p>While there is plenty of evidence that sunscreens can prevent photoageing, many only block the UV (ultraviolet) range of the solar spectrum. In the case of photoageing, exposure to <a href="https://pubmed.ncbi.nlm.nih.gov/34585779/">visible radiation</a> (particularly <a href="https://www.nature.com/articles/s41598-018-30738-6">blue light</a>) and <a href="https://pubmed.ncbi.nlm.nih.gov/19675547/">infrared</a> have all been shown to contribute to photoageing. Basically, this means that sunscreens can’t protect against photoageing entirely, but can reduce it significantly.</p> <p>Some <a href="https://www.sciencedirect.com/science/article/pii/S1011134421002517">newer solar filters</a> used in sunscreens have been developed which can block some blue light. Other ingredients sometimes added to sunscreens (<a href="https://pubmed.ncbi.nlm.nih.gov/30071261/">such as antioxidants</a>) have also been shown to prevent the production of MMPs and reduce <a href="https://pubmed.ncbi.nlm.nih.gov/34789788/">reactive oxygen species</a> – which will likely help in the fight against photoageing beyond the UV spectrum, too. Antioxidants may also protect against factors such as <a href="https://pubmed.ncbi.nlm.nih.gov/31927691/#:%7E:text=Recent%20findings%3A%20Traffic%2Drelated%20air,effects%20on%20premature%20skin%20aging.">pollution</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/17951030/">smoking</a>, which are both linked to faster ageing.</p> <p>Photoageing is a cumulative process that occurs over time. Doing anything you can to <a href="https://www.britishskinfoundation.org.uk/how-to-stay-safe-in-the-sun">limit exposure</a> will slow this process – such as covering up with clothing when you go outside. But choosing the right kind of sunscreen may also help somewhat.</p> <p>The best product to use comes down largely to personal preference. But in general, the higher the SPF, the greater protection you’ll have against photoageing. You should also try to find a sunscreen with five-star UVA protection on the label, which will help protect against the broadest range of UV radiation.</p> <p>Be sure to regularly use sunscreen or SPF-containing products from spring to autumn. If you’re going to be getting a lot of sun (such as on a beach holiday) it’s best to use a higher SPF product and reapply regularly. Although some people recommend wearing sunscreen even in winter, this is unlikely to be of much benefit to people living in the UK, as UV radiation is lowest this time of year. But if you go on a skiing holiday or live somewhere with lots of snow, sunscreen will still be beneficial as snow reflects solar radiation.</p> <p>All the evidence suggests that by far the most effective way to prevent photoageing is with the use of sunscreens, as these prevent damage from happening in the first place. Now with more choice than ever and formulations always being improved, it’s just a matter of finding what product works best for you.</p> <p>But a final word of warning: slathering on sunscreen before sitting out tanning won’t be enough to protect you completely – and this goes beyond photoageing. Too much sun exposure can carry other risks – such as sunburn and skin cancer – which is something to bear in mind during the summer months.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/sunscreen-heres-why-its-an-anti-ageing-skincare-essential-187322" target="_blank" rel="noopener">The Conversation</a>. </em></p>

8 essential rules for working out in the winter

<p><strong>Baby, it’s cold outside</strong></p> <p>It can be tough to find the motivation to do an outdoor workout once winter strikes with low temperatures, wind chill, rain and dark nights. However, don’t let the cold weather deter you from accomplishing your fitness goals – even in the winter.</p> <p>Read on down below and follow our expert tips to stay fit, warm and motivated this winter.</p> <p><strong>Dress for the weather</strong></p> <p>Workout clothes are much more than just for aesthetics – they’re designed for the type of exercise you’re doing as well as the climate and weather that you’re training in. “The most important elements to take into consideration for outdoor workouts are wind chill and precipitation,” says Kaitlyn Noble, a personal trainer. Layers will protect you on a cold, wind-free day, however, wind chills can easily penetrate thinner items of clothes, which is why wind-resistant materials are so crucial. And of course, if your clothes are wet, you’ll have no protection from the frigid temperature, so be sure to wear a water-resistant outer layer when it’s raining. Your workout wear should always be water wicking in the cold too, like with thermal leggings, since sweat-soaked clothes can freeze in really cold conditions.</p> <p><strong>Active warm-ups</strong></p> <p>“Imagine a rubber band… it’s flexible, bendy and pulls right back to its shape. Now imagine that same rubber band, but frozen. If you try to pull too hard before it’s thawed out, it’ll snap,” explains trainer Ashley Wilking. Your muscles are like rubber bands, you need to gradually warm them up to prevent injury.</p> <p>Noble suggests starting to heat up your larger muscles, like quads and hamstrings, with light stretching, jumping jacks and lunges indoors before heading outside. If you’re commuting to a class or gym, consider speed walking to get your heart rate up.</p> <p><strong>Don’t skip your cool down</strong></p> <p>Make sure to give your body time to cool down and stretch before you rush out of your workout class or the gym. “You don’t want to go from a heart-pumping, sweat-drenched working session, straight into the cold or a sedentary position, like sitting at a desk,” says Wilking. Stretching post-workout is crucial – but particularly after a cold-weather workout to keep your body safe from injury.</p> <p><strong>Protect your head and hands</strong></p> <p>While only about 10 percent of your body heat escapes from your head, as opposed to 70 percent as previously believed (just one of the many myths about the human body), wearing a hat in cold weather – especially when doing outdoor activities, like biking, running and even on your daily stroll – is still important. “Choose a hat made of a warm, breathable material that also protects your ears,” says Noble. Your hands are another body part that are likely to feel the chill, which means gloves are a must. Pro tip: Choose a pair with touchscreen fingers, so you’re not taking them off and on to change music.</p> <p><strong>Hydrate</strong></p> <p>You may feel like you sweat less in cold weather, but don’t be fooled, you still need to drink up. Dehydration increases your risk of injury significantly and will slow down your performance. Stay hydrated by drinking room temperature water before, during and after your workout. “Many people find that cold water is harder to drink, so by keeping your water room temperature you can hydrate more easily,” says Amanda Kloots, creator of The Rope and The Dance studios.</p> <p><strong>Choose reflective gear</strong></p> <p>Since winter months also mean less daylight, your workout is more likely to happen in the dark. Make yourself visible to cars, cyclists and other pedestrians by wearing reflective items, like shoes, backpacks and jackets.</p> <p><strong>Don’t forget sun protection</strong></p> <p>Just because it’s cold doesn’t mean you can’t get burnt. Don’t skimp on the sunscreen. Continue wearing sun protection during daylight hours, regardless of the temperature.</p> <p><em><strong>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/fitness/8-essential-rules-for-working-out-in-the-winter" target="_blank" rel="noopener">Reader’s Digest</a>.</strong></em></p> <p><em>Image: Shutterstock</em></p>

Genius uses for essential oils in your home

<p><strong>Use as a natural fragrance</strong></p> <p>With all the talk about the dangers of phthalates, which are found in many commercial air fresheners and have been shown to decrease thyroid function over time, it’s nice to know that essential oils can be used as an all-natural scent booster. And you don’t even need to own a diffuser. Place sweet orange, lavender, or lime essential oil on a cotton ball and tape it to the back of a flower pot or the bottom of a chair, advises Erin Stewart, certified aromatherapist, herbalist, and founder of AromaCulture.</p> <p>“It will release the aroma of the essential oil into the air and leave your house smelling fresh,” she says. She also recommends placing a drop or two of essential oil into a bowl of clay diffuser beads or pebbles in the bathroom. “The clay will act as a diffuser, slowly releasing the aroma of the essential oil into the room and acting as a natural air freshener.”</p> <p><strong>Disinfect your bench tops</strong></p> <p>Since many essential oils have antibacterial, antiviral and antifungal properties, they are well-suited for use in simple homemade cleaning products. Plus, think of all the cash you’ll save on overpriced (and overly processed) commercial varieties. </p> <p>Stewart recommends adding 2 to 3 drops of lemon, lavender, sweet orange, or tea tree essential oil to some diluted liquid castile soap in a small spray bottle. “You can use this combination to wipe down your kitchen and bathroom counters and other non-porous surfaces,” she says.</p> <p><strong>Clean your toilet</strong></p> <p>You can even use the same essential oils as for countertop cleaners – lemon, lavender, sweet orange, or tea tree – to keep your toilet spick and span. Stewart recommends DIYing your own “toilet tabs” by stirring a couple of drops of one of these essential oils into a bowl of baking soda, spraying the mixture lightly with water and then pressing the baking soda mixture into a silicon mould (like for ice cubes or brownies). </p> <p>“Let it sit overnight to dry and, the next morning, remove the tabs from the mould and store them in an airtight jar,” she says. “Toss one into the toilet before you shower each day and flush when you get out of the shower to keep your toilet fresh between deep cleanings.”</p> <p><strong>Swap out grocery items</strong></p> <p>Instead of buying a heap of herbs that will go bad in a week, replace them with essential oils. “The rule is to use one drop of essential oil per tablespoon of herbs in your favourite recipe,” says Maat van Uitert, essential oil expert. Essential oils can also be used in desserts. </p> <p>“If you love chocolate mint patties, you can make a homemade version using one drop of peppermint – and, if you’re trying to lose weight and don’t like the taste of water, you can add one drop of orange essential oil to 250ml of water to make it more palatable.” You can also add 1 to 2 drops of lemon essential oil to your water bottle to give it some zing.</p> <p><strong>Wash fresh fruit and veggies</strong></p> <p>Just thinking about how many hands have touched the surfaces of the fruits and vegetables you buy at your local supermarket can give you a ballpark idea of the amount of germs that may be on them – and that’s not including any pesticides that may have been sprayed on them at the farm. </p> <p>As well as washing them with water, use essential oils. Sally Pansing Kravich, celebrity holistic nutritionist and author, recommends adding five drops of lemon essential oil to a large bowl of water to wash fruits and veggies.</p> <p><strong>Protect lawns and gardens</strong></p> <p>Most commercial products for pest control aren’t kid- or pet-safe and contain chemicals harmful to your local ecosystem, notes van Uitert. </p> <p>His advice: If insects are destroying your lawn or garden, combine 10 drops of essential oil with 250ml of water and castile soap for organic pest control. Use a spray attachment with your hose and spray the insects away.</p> <p><strong>Keep flying bugs away</strong></p> <p>One of the few downsides to summer weather is the influx of relentless outdoor pests. With so many dangerous chemical combinations being used in commercial insect repellents, why not make your own more affordable and less harmful spray? </p> <p>For a great natural alternative to chemical bug sprays with DEET in them, Ed Foy, co-founder of Clear Scents, suggests trying this recipe: In a small spray bottle, combine 60-120ml of distilled water, 45ml witch hazel or vodka, and 30 to 50 drops of your favourite essential oil. You can add more or less essential oil depending how strong you want the fragrance to be. Use the spray around your outdoor seating areas.</p> <p><strong>Deter crawling bugs</strong></p> <p>If ants are invading your home – or camping tent – cinnamon essential oil can help. “The cinnamon interacts with their nervous system and prevents them from communicating with other ants, forcing them to leave the area,” says van Uitert. </p> <p>“Even better, you won’t have to worry about your child or pet ingesting toxins.” Lemongrass is another great solution. Try diluting 10 to 20 drops of the stuff in 60-120ml of water. Shake it up and spray the area where you’re hoping to ward off bugs. One whiff of the stuff and they’ll head in another direction.</p> <p><strong>Boost the scent of laundry</strong></p> <p>If your detergent isn’t leaving your clothes smelling quite as fresh as you’d like, it’s not that you’re making these <a href="https://www.readersdigest.com.au/food-home-garden/home-tips/14-laundry-myths-that-are-ruining-your-clothes" target="_blank" rel="noopener">common laundry mistakes</a>. It’s that you haven’t been taking advantage of non-toxic scenting power of essential oils. Try adding essential oils to laundering or drying clothes to give them a clean, natural smell. </p> <p>“Whether you’re using a homemade or store-bought detergent or fabric softener, just add several drops of your favourite essential oil such as lavender, lemongrass or peppermint, and launder as usual,” says Foy. “You can also condition your clothes in the dryer by adding essential oil to any wool dryer ball.” This hypoallergenic alternative is sure to leave your clothes feeling soft and smelling great every time.</p> <p><strong>Spray away sunburn</strong></p> <p>You probably already know that applying lemon essential oil to your hair while you’re out in the sun can create natural blonde highlights, but you might be surprised to know that essential oils can also take the sting away from a sunburn. </p> <p>“If you’ve been out in the sun too long, combine one-half cup witch hazel with 3 tablespoons of pure aloe vera gel and five drops of lavender essential oil in a spray bottle,” suggests van Uitert. Shake to mix and apply to your body as needed. “The aloe vera and lavender are soothing!”</p> <p><strong>Sooth pain</strong></p> <p>Have a headache? Sure, you can pop an over-the-counter pain medication like aspirin or ibuprofen, but another option, and an all-natural one at that, is to treat pain with essential oils. </p> <p>“Combine almond oil with four drops peppermint essential oil, two drops rosemary essential oil, one drop lavender essential oil, one drop chamomile essential oil, and one drop frankincense essential oil,” suggests Peggy O’Kelly, essential oil expert. “Shake up and apply to temples, pulse points, and back of neck.”</p> <p><strong>Relieve allergies</strong></p> <p>Seasonal allergies can be downright debilitating. And, while there are countless store-bought medications and products that promise to provide relief, there are plenty of all-natural solutions for stopping seasonal allergies in their tracks. One is through the use of an aromatherapy inhaler (they look like a lip balm tube with a cotton ‘wick’ inside). </p> <p>“On the cotton wick, add four drops of cedarwood, four drops of sweet orange and seven drops of eucalyptus,” suggests Butje. “Close the inhaler up and use it as needed to calm sniffling and sneezing. It will last two months.”</p> <p><strong>Clean carpets</strong></p> <p>Having a clean and fresh-smelling carpet can be a lot more affordable when you DIY your own cleanser. In fact, as long as you have baking soda and some divine essential oils, you’re good to go. “Baking soda is great for removing pet and food odors, and essential oils will leave your carpet and entire room smelling brand new,” says Kravich.</p> <p>She recommends vacuuming first to pick up any surface dirt or hair and then combining two cups of baking soda with one of the following combinations: 10 drops orange or lemon, five drops lemongrass and five drops tea tree, or 10 drops lavender essential oil, five drops clove and five drops cinnamon. “Sprinkle the mixture over the entire area of your carpet and use a sponge or dry brush to make sure it penetrates to the carpet bottom,” she adds. “Let stand for at least two hours or more and then vacuum thoroughly.”</p> <p><strong>Get grime off floors</strong></p> <p>People have been cleaning their homes with water and vinegar for decades (check out these 95 household uses for vinegar), and the all-natural solution still stands the test of time. But, let’s be honest, no one really enjoys the lingering smell of vinegar. And if you use it on your floors, the scent is sure to make its way into the entire room. </p> <p>Instead, Priti Robyn Ross E-RYT, advanced yoga instructor and wellness advocate for dōTERRA essential oils, recommends adding five drops each of orange and lemon essential oils into a mixture of one bucket of warm water and one cup white vinegar. It kills the smell of the vinegar, and citrus essential oils add antibacterial and anti-fungal properties.</p> <p><strong>Ease aching muscles</strong></p> <p>There’s a good reason just about every massage therapist incorporates essential oils into his or her practice: They have incredibly powerful soothing effects when applied topically to the skin. One study found essential oils to be beneficial not only for relaxation, sleep, and pain relief, but also for a reduction of depressive symptoms in dementia patients. </p> <p>Foy recommends trying this soothing recipe on aching muscles: In a small bottle, combine a ½ ounce grapeseed oil and 8 to 10 drops each of lavender, peppermint, and eucalyptus oil. Shake together and rub on areas for added comfort and relaxation.</p> <p><strong>Soften and grow your hair</strong></p> <p>Tea tree oil, also known as melaleuca oil, has been used for centuries to promote and maintain healthy, natural looking hair, according to Foy. “The strong antifungal and antiseptic properties of this oil make it extremely effective at combating common ailments such as dandruff, itchy scalp and head lice,” he says. </p> <p>One study published in the Archives of Dermatology even linked essential oil use to hair growth in patients with alopecia. Foy recommends adding several drops of your favourite essential oil to your regular hair conditioner and use as normal, or massage it directly into the scalp after a bath or shower.</p> <p><strong>Customise the scent of your lotion</strong></p> <p>Unscented lotion and essential oils are a match made in heaven. “There are endless options available for mixing your favourite scents with any unscented lotions,” says Foy.</p> <p>“Most lotions have already been formulated to restore moisture to your skin, but adding in your own essential oils will only bring additional benefits.” Lavender, lemongrass and tea tree are some of the more popular oils that have been dermatologically tested and proven to help restore and maintain the natural properties of your skin.</p> <p><strong>Give yourself a facial</strong></p> <p>One of the easiest ways to incorporate essential oils into your skin care routine is to treat yourself to a weekly facial steam – they’re surprisingly easy to do! Stewart recommends boiling a cup or two of water and pouring it into a heat safe bowl. “Place the bowl on the table where you’re going to sit for your facial steam, and add the hot water.” </p> <p>Next, add one drop of a skin-nourishing essential oil like lavender or rose to the water of the bowl. Close your eyes and hold your clean, makeup-free face 30cm above the bowl for 1 to 3 minutes. “Keep your eyes closed throughout the whole steam, and if it feels too hot or uncomfortable, give yourself a little more space between you and the bowl.”</p> <p><strong>Clean makeup brushes</strong></p> <p>Believe it or not, beauty experts recommend washing your makeup brushes once a week But store-bought cleaners can be pricey, and if you break out easily you might be concerned about the ingredient list on manufactured varieties. Instead, make your own brush cleanser using essential oils. </p> <p>O’Kelly recommends combining two tablespoons witch hazel, ½ teaspoon of extra virgin olive oil, two teaspoons of castile soap, and 20 drops of tea tree essential oil, which has antifungal properties. Shake it well and then pour it into a bowl. Gently swirl your brushes around in the mixture until clean. Rinse with water, squeeze out excess liquid, and set out to try.</p> <p><strong>Deodorise sports gear</strong></p> <p>If you have smelly athletes running around your home, essential oils can help get rid of that icky, sweaty smell. </p> <p>Ross recommends adding two drops each of tea tree and lemon essential oils in one quart of warm water along with four tablespoons of baking soda. Mix it together and use to clean everything from jerseys to cleats, sports accessories and running shoes.</p> <p><strong>Remove shower curtain scum</strong></p> <p>That dark, filmy, bacteria that builds up when water interacts with soap, dirt and other substances during your shower is undoubtedly disgusting – not to mention that mould and mildew can literally make you sick. </p> <p>Rather than apply harsh, commercial products that contain a laundry list of dangerous chemicals, try this solution that Ross recommends. “Fill a 475ml spray bottle with warm water and add in four drops eucalyptus oil and four drops tea tree oil. Spray onto your shower for natural mould-killing action!”</p> <p><strong>Freshen your garbage bin</strong></p> <p>Even if you’re careful not to let any waste touch the rim of your garbage bom, it’s inevitable that the bag will start to smell. Instead of spraying store-bought freshener, Ross recommends a combination of purifying and odour-eliminating essential oils. </p> <p>“Add several drops of wild orange, lemon and tea tree essential oils to a cotton ball,” she says. “You’ll be amazed at how well it detoxifies your whole bin!”</p> <p><strong>Ease digestive discomfort</strong></p> <p>Before you reach for that over-the-counter digestive remedy, try this all-natural, essential oil-infused solution. “Peppermint and ginger make an excellent digestive blend, so apply the oils all over your body, from your stomach to your feet,” suggests Ross. </p> <p>Studies have found both peppermint and ginger to be useful in soothing an upset stomach and aiding digestion, particularly in relieving irritable bowel syndrome.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/home-tips/genius-uses-for-essential-oils-in-your-home?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

The ocean is essential to tackling climate change. So why has it been neglected in global climate talks?

<p>Climate change is commonly discussed as though it’s a uniquely atmospheric phenomena. But the crisis is deeply entwined with the ocean, and this has largely been neglected in international climate talks.</p> <p>The latest international climate negotiations made some progress by, for the first time, <a href="https://www.becausetheocean.org/the-ocean-anchored-in-glasgow-climate-pact/">anchoring oceans</a> permanently into the multilateral climate change regime. But the <a href="https://unfccc.int/process-and-meetings/conferences/glasgow-climate-change-conference-october-november-2021/outcomes-of-the-glasgow-climate-change-conference">Glasgow Climate Pact</a> is still leagues from where it needs to be to adequately reflect the importance of oceans to our climate system.</p> <p>Most countries have targets for land-based emissions – but there are no such targets for oceans. Yet the ocean plays a vital role in helping balance the conditions humans and most other species need to survive, while also offering a substantial part of the solution to stop the planet warming over the crucial limit of 1.5℃ this century.</p> <p>So how can oceans help us tackle the climate crisis? And what progress has been made in international negotiations?</p> <h2>The ocean’s incredible potential</h2> <p>Since industrialisation, the ocean has absorbed <a href="https://www.ipcc.ch/assessment-report/ar5/">93% of human-generated heat</a> and <a href="https://www.science.org/doi/10.1126/science.aau5153">one-third of anthropogenic carbon dioxide</a> (CO₂). The consequences of this are profound, including the thermal expansion of water (the key cause of sea level rise), ocean acidification, <a href="https://www.iucn.org/theme/marine-and-polar/our-work/climate-change-and-oceans/ocean-deoxygenation">deoxygenation</a> (oxygen loss), and forcing marine life to redistribute to other places.</p> <p>Alarmingly, this may one day lead the ocean to reverse its role as a carbon sink and release CO₂ <a href="https://unesdoc.unesco.org/ark:/48223/pf0000376708">back into the atmosphere</a>, as its absorption ability declines.</p> <p>Equally important is ocean-based climate mitigation, which could provide <a href="https://www.wri.org/insights/turning-tide-ocean-based-solutions-could-close-emission-gap-21">more than 20% of the emissions reductions</a> needed for the 1.5℃ goal.</p> <p><a href="https://images.theconversation.com/files/432511/original/file-20211117-25-34h4c8.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/432511/original/file-20211117-25-34h4c8.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Cargo ships" /></a> <span class="caption">The shipping industry is responsible for about 3% of global emissions.</span> <span class="attribution"><span class="source">Andy Li/Unsplash</span>, <a href="http://creativecommons.org/licenses/by/4.0/" class="license">CC BY</a></span></p> <p>Crucially, we must see changes to maritime industries. The shipping industry alone has a similar carbon footprint to Germany – if shipping were a country it would be the world’s sixth-largest emitter. Although high on the <a href="https://theconversation.com/the-shipping-sector-is-finally-on-board-in-the-fight-against-climate-change-95212">International Maritime Organisation’s agenda</a>, the <a href="https://theconversation.com/to-reach-net-zero-we-must-decarbonise-shipping-but-two-big-problems-are-getting-in-the-way-170464">decarbonisation of shipping</a> still lacks <a href="https://www.maritime-executive.com/article/let-s-be-honest-un-secretary-general-slams-imo-s-progress-on-co2">adequate targets or processes</a>.</p> <p>Oceans can also provide climate-safe, sustainable food choices. Current food systems, such as emissions-intensive agriculture, fishing, and processed foods are responsible for <a href="https://www.nature.com/articles/s43016-021-00225-9">one-third of global emissions</a>. Considerable environmental (and health) benefits can be gained by shifting our diets to sustainable “<a href="https://theconversation.com/how-fish-can-still-be-part-of-a-more-sustainable-food-future-167944">blue foods</a>”.</p> <p>These include seafoods sourced from fisheries with sustainable management practices, such as avoiding overfishing and reducing carbon emissions. Markets and technologies should also be geared towards the large-scale production and consumption of aquatic plants such as seagrasses.</p> <p>There’s also a wealth of opportunity in “blue carbon” – capturing CO₂ in the atmosphere by conserving and restoring marine ecosystems such as mangroves, seagrasses and salt marshes. However, the success of nature-based solutions depends on a healthy ocean ecosystem. For example, there are emerging concerns around the impact of <a href="https://theconversation.com/oil-companies-are-ploughing-money-into-fossil-fuelled-plastics-production-at-a-record-rate-new-research-169690">plastic pollution</a> on plankton’s ability to absorb CO₂.</p> <p><a href="https://images.theconversation.com/files/432512/original/file-20211117-21-1lqaa5q.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/432512/original/file-20211117-21-1lqaa5q.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /></a> <span class="caption">Conserving mangroves is an important way to sequester carbon from the atmosphere.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <p>But perhaps the greatest impact would come from adopting offshore renewable energy. This has the potential to offer <a href="https://www.oceanpanel.org/climate">one-tenth of the emissions reductions we need to reach the 1.5℃ goal</a>. The International Energy Agency has estimated offshore wind could <a href="https://www.iea.org/reports/offshore-wind-outlook-2019">power the world 18 times over its current consumption rate</a>.</p> <h2>Climate talks are making slow progress</h2> <p>For more than a decade, the inclusion of oceans in climate talks has been piecemeal and inconsistent. Where they have been part of negotiations, including at COP26, talk has focused on the potential for coastal areas to adapt to climate change impacts such as sea-level rise, as first raised in international fora <a href="http://www.islandvulnerability.org/slr1989/declaration.pdf">in 1989</a> by small island states.</p> <p>The final COP26 agreement, known as the <a href="https://unfccc.int/process-and-meetings/conferences/glasgow-climate-change-conference-october-november-2021/outcomes-of-the-glasgow-climate-change-conference">Glasgow Climate Pact</a>, made slight progress.</p> <p>The pact recognised the importance of ensuring the <a href="https://unfccc.int/sites/default/files/resource/cma3_auv_2_cover%20decision.pdf">ocean ecosystem’s integrity</a>. It established the “the Ocean and Climate Change Dialogue” as an annual process to strengthen ocean-based action. And <a href="https://unfccc.int/sites/default/files/resource/cop26_auv_2f_cover_decision.pdf">it invited</a> UNFCCC bodies to consider how to “integrate and strengthen ocean-based action into existing mandates and workplans” and report back.</p> <p>While these are positive measures, at this stage they don’t require action by parties. Therefore, they’re only a theoretical inclusion, not action-oriented.</p> <p>We still lack national targets and clear, mandatory international requirements for countries to consider sinks, sources and activities beyond the shoreline in their climate planning and reporting.</p> <p>Where COP26 did progress was its focus on whether ocean impacts and mitigation will finally be brought into the mainstream climate agenda. For the first time in five years, a new <a href="https://www.becausetheocean.org/wp-content/uploads/2021/11/Final-Draft-BtO3_31_Oct_2021.pdf">“Because the Ocean” declaration</a> was released, which calls for the systematic inclusion of the oceans in the UNFCCC and Paris Agreement process.</p> <h2>What do we do now?</h2> <p>What’s now needed is a list of mandated requirements that ensure countries report on and take responsibility for climate impacts within their maritime territories.</p> <p>But as COP26 president Alok Sharma said of the summit as a whole, it was a “fragile win”. We still lack any reference to consistency with existing mechanisms, such as the <a href="https://www.un.org/depts/los/index.htm">law of the sea convention</a> or how funding will be allocated specifically to oceans.</p> <p>As such, the actual impact of COP26 on the inclusion of oceans in climate action remains uncertain. It will depend on how the UNFCCC bodies respond to these directives, and their success in extending obligations to state parties.</p> <p>Responding to the climate crisis means we need to stop pretending the ocean and atmosphere are separate. We must start including ocean action as a routine part of climate action.</p> <p><span><a href="https://theconversation.com/profiles/dr-sali-bache-1286674">Dr Sali Bache</a>, Strategic Advisor in International Policy and Oceans , <em><a href="https://theconversation.com/institutions/climateworks-australia-984">ClimateWorks Australia</a></em></span></p> <p>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

A successful COP26 is essential for Earth’s future. Here’s what needs to go right

<p>A week from Monday, a crucial round of United Nations climate change negotiations will begin in Glasgow and the stakes could not be higher. By the end, we’ll know how far nations are willing to go to address humanity’s biggest challenge.</p> <p>So is COP26 on track for success? There are reasons to be hopeful.</p> <p>More than 100 countries, including China, the United States and United Kingdom, have already pledged to reach net-zero emissions. Globally, renewable energy is <a href="https://www.npr.org/2021/05/11/995849954/renewable-energy-capacity-jumped-45-worldwide-in-2020-iea-sees-new-normal">booming</a>, <a href="https://theconversation.com/asias-energy-pivot-is-a-warning-to-australia-clinging-to-coal-is-bad-for-the-economy-169541">the tide is turning</a> against fossil fuels, and the <a href="https://www.climatecouncil.org.au/resources/markets-moving-economic-costs-australias-climate-inaction/">economic costs</a> of not acting on climate change are becoming ever more obvious.</p> <p>But if history has taught us anything, no country at the summit will agree to do more on climate change than it believes it can do at home. In other words, domestic politics is what drives international negotiations.</p> <h2>What will happen in Glasgow?</h2> <p>The first COP, or Conference of Parties, was held in Berlin in 1995. About a quarter of a century later, it will meet for the 26th time.</p> <p>COP26 will determine the direction of key aspects of the fight against global warming. Chief <a href="https://theconversation.com/what-is-cop26-heres-how-global-climate-negotiations-work-and-whats-expected-from-the-glasgow-summit-169434">among them</a> is how well nations have implemented their commitments under the Paris Agreement to limit global warming to well below 2℃, and the extent to which they will increase that ambition.</p> <p>Other issues on the agenda include climate finance to developing nations, adaptation to climate change and carbon trading rules.</p> <p>Starting on October 31, hundreds of government delegates will attend for two weeks of complex and intense negotiations over the specific text of the agreement.</p> <p>Typically, what delegates can’t sort out is left to political leaders, who negotiate the thorniest issues. Historically, final agreement occurs in the wee hours of the final session.</p> <p>Outside the convention centre is the unofficial COP, which is more like a world climate expo. Thousands of representatives from business, civil society and elsewhere — from bankers and billionaires, to students and survivalists – gather for panel discussions, exhibitions and protests.</p> <h2>Progress is slow</h2> <p>Global climate talks involve people from all around the globe with different interests, preferences, and mandates (what negotiators sometimes call “red lines”). As you can imagine, progress can be slow.</p> <p>Almost 200 nations are signed up to the Paris Agreement, and agreement is by consensus. That means just one country can hold up progress for hours or even days.</p> <p>Cynics – more often than not, those wanting to <a href="https://theconversation.com/fossil-fuel-misinformation-may-sideline-one-of-the-most-important-climate-change-reports-ever-released-165887">delay climate action</a> – claim the whole process is nothing more than a talk shop.</p> <p>It’s true, talk is slow. But it’s also much better than coercion, and without the negotiations countries would face much less pressure to act. It’s also true that over the last 25 years, these negotiations have redefined how the world thinks and acts on climate change.</p> <p>After all, it was the COP in Paris that tasked the Intergovernmental Panel on Climate Change to provide a <a href="https://www.ipcc.ch/sr15/chapter/spm/">special report</a> on the impacts of global warming of 1.5℃ above pre-industrial levels. Its findings reverberated around the world.</p> <p><a href="https://theconversation.com/new-un-report-outlines-urgent-transformational-change-needed-to-hold-global-warming-to-1-5-c-103237">It found</a> if we’re to limit warming to 1.5℃, we must reduce carbon dioxide emissions by 45% by 2030, reaching near-zero by around 2050.</p> <p>But since the Paris Agreement was struck, global emissions have continued to rise, even with the impacts of COVID-19. COP26 is a major test of whether the world can turn this around and avert runaway global warming.</p> <p><a href="https://images.theconversation.com/files/427720/original/file-20211021-15-1xxiq11.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/427720/original/file-20211021-15-1xxiq11.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /></a></p> <h2>Will Glasgow deliver?</h2> <p>For the Glasgow summit to be deemed a success, a few things need to go right. First of all, countries need to commit not simply to net-zero targets by 2050, but stronger targets for 2030. <a href="https://www.nature.com/articles/d41586-018-06876-2">Without them</a>, there’s zero chance the world will hold the rise in global temperatures to 2℃.</p> <p>Major emitters will also need to support developing countries with the finance and technologies to enable them to transition to clean energy and adapt to climate change impacts, including severe flooding and prolonged droughts.</p> <p>Other issues, such as rules around international carbon markets, will also be on the agenda, but even the most robust carbon markets are <a href="https://www.pnas.org/content/117/16/8664">unlikely</a> to deliver emissions cuts at the speed scientists warn is necessary to avert disaster.</p> <p>There are signs of hope. The US has been, historically, the most important player in the international negotiations, and President Joe Biden has outlined <a href="https://theconversation.com/biden-says-the-us-will-rejoin-the-paris-climate-agreement-in-77-days-then-australia-will-really-feel-the-heat-149533">the most ambition climate plans</a> in the nation’s history ahead of the Glasgow summit.</p> <p>The US, together with the UK, the European Union and a host of smaller countries, <a href="https://theconversation.com/glasgow-showdown-pacific-islands-demand-global-leaders-bring-action-not-excuses-to-un-summit-169649">including those in the Pacific</a>, comprise a strong and influential coalition of countries gunning to limit warming to 1.5℃.</p> <p>So what stands in their way? Well, what countries are willing to commit to in Glasgow is not so much a function of what happens in Glasgow, but of <a href="https://www.e-elgar.com/shop/gbp/the-politics-of-climate-change-negotiations-9781783472109.html">domestic politics</a> in their capitals.</p> <p>This is why Democrats in Washington are feverishly working to ensure <a href="https://www.washingtonpost.com/climate-environment/2021/10/19/climate-reconciliation-biden-white-house/">Biden’s massive budget bill</a>, which includes measures such as a clean electricity program, makes its way through Congress. The bill is vital to the president’s commitment to halve emissions by 2030.</p> <p>It’s also why astute observers have been fixated on well-known climate laggards heavily reliant on fossil fuels, such Brazil, Russia, and Australia, to see whether any domestic political developments might lead these nations to commit to more ambitious targets by 2030.</p> <p>And it’s why lobbyists for industries that stand to lose from climate change – namely oil, gas and coal – know to kill off climate action in Glasgow, they need to kill off climate action at home.</p> <p>International negotiations are often referred to as a <a href="https://www.jstor.org/stable/2706785">two-level game</a>. Changes at the domestic level can enable new and, hopefully, ambitious realignments at the international level.</p> <p>Will these realignments occur? We don’t have long to find out, but at the domestic level in many nations, there has never been a worse time to advocate for fossil fuels – and this should give us all hope that action on climate change is more likely than ever.</p> <p><span><a href="https://theconversation.com/profiles/christian-downie-762">Christian Downie</a>, Associate Professor, <em><a href="https://theconversation.com/institutions/australian-national-university-877">Australian National University</a></em></span></p> <p>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
