Will Harlow, over-50s specialist physio, shows us how to turn back the clock:

Reach for youthfulness

Most of mobility is lost through lack of use. If we’re afraid of stretching fully, we’ll stop a little short, and then our body will adapt, and the shorter reach becomes our new maximum reach. This process continues until such a time as we are completely stiff.

So, never has “use it lose it” been so critical! With this in mind, here are 5 exercises to take your range of motion back to its previous levels:

  1. Open the gate: stand tall holding a wall or similar support, shift your weight onto one leg, lift your other knee, and move it up, out to the side, and around in a smooth circle before placing your foot back down; keep your back upright throughout to gently mobilize your hips and wake up the surrounding hip muscles, supporting long-term hip joint health.
  2. Dynamic hamstring sweep: stand with one foot forward and your heel on the floor, keep your front leg straight and your back knee slightly bent, then hinge down as you sweep your hands along your front leg and return upright; move in and out of the stretch in a controlled way to warm up your hamstrings before activity (but skip this one if you have sciatica, like we mentioned yesterday).
  3. Overhead reach: sit upright away from a chair back with your feet flat on the floor, interlace your fingers or stack them together, reach your arms overhead, turn your palms upwards, and push gently towards the ceiling; this opens your chest, improves your shoulder mobility, and helps counter stiffness from ergonomically unfriendly phone use, poorly angled typing, and other daily bad posture habits.
  4. Seated side bend: sit tall with your hands crossed over your chest, keep your head aligned with your shoulders, and slowly lean your whole torso to one side without lifting your hips, then return to center and switch sides; move slowly and with control to explore your spinal range of motion without forcing it.
  5. Towel shoulder stretch: hold a towel overhead with one hand and grasp it behind your back with your other hand, keeping your back upright as you gently pull upwards to lift your lower arm until you feel a stretch in the front of your shoulder, then lightly guide your elbow forwards; hold comfortably, ease off slowly, and repeat on the other side to improve shoulder range of motion for everyday reaching tasks.

  • Can what you eat during pregnancy and breastfeeding affect whether your child develops food allergies?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Many questions pop up when you’re growing or raising a new baby.

    Among them, women often wonder if what they eat during pregnancy or breastfeeding will affect whether or not their child will have a food allergy.

    Researchers have also been trying to answer this question for many years.

    A baby’s exposure to food allergens during pregnancy and via breast milk is thought to be important. Experts believe it could allow the child to start developing helpful immune responses so they tolerate food allergens in their diet in future.

    But to what degree this theory plays out, and whether a mother’s diet influences their child’s likelihood of developing food allergies, isn’t yet clear. Here’s what we know so far.

    The science of food allergies

    A food allergy occurs when the body’s immune system responds to a particular food as if it was harmful to the body.

    In Australia, foods which commonly cause allergies include egg, cow’s milk, peanut, tree nuts, sesame, soy, wheat, fish and other seafood (this can vary a little in different countries). Although almost any food can cause an allergic reaction.

    For people with food allergies, symptoms can appear within minutes of eating the food. These symptoms can include a swollen face, lips or eyes, hives or welts on the skin, vomiting, trouble breathing, and persistent dizziness or collapse.

    In pregnancy, food allergens can cross the placenta and can be detected in amniotic fluid, from which they reach the baby’s gastrointestinal tract when the baby swallows.

    After birth this process continues when food allergens pass from breast milk to the baby’s gastrointestinal tract. Both of these pathways lead to early life exposure to different foods.

    This is thought to help the baby’s developing immune system to accept food allergens when they’re introduced once the child starts eating solids. In other words, the immune system may be more likely to see the food as harmless and not mount an allergic response against the food.

    Along with food allergens, babies also receive beneficial antibodies in breast milk. Levels of food allergen-specific antibodies, which could offer protection against allergies, have been found to be higher in babies whose mothers ate more of foods including egg, peanut, cow’s milk and wheat during early breastfeeding.

    Lower levels of these beneficial antibodies in the blood have been linked with higher chances of babies developing food allergies.

    Research is trying to answer the question

    While there are scientific explanations for how a woman’s diet during pregnancy and breastfeeding could influence her child’s likelihood of developing a food allergy, we don’t have conclusive evidence to tell us exactly what the best diet is to prevent allergies.

    Some studies have tried to look at this, but results have been inconsistent because they have been done in different populations, diet has been assessed in different ways, and they have not always been able to account for other factors that might influence both diet and food allergy risk.

    Current research is trying to understand this further. A large Australian study, the PrEggNut Study, is testing whether the amount of egg and peanut mothers eat during pregnancy and breastfeeding affects their child’s risk of having an egg or peanut allergy.

    More than 2,100 mothers were randomly assigned to eat either higher or lower amounts of egg and peanut from mid-pregnancy until their baby was four months old. Results are expected next year.

    Another Australian study, the Nuts For Babies Study, is testing whether the amount of peanuts and cashew nuts mothers eat during breastfeeding can reduce the chances of their child developing a peanut or cashew nut allergy.

    This study has recently commenced and is looking for 4,000 pregnant women living in Western Australia or Victoria and who are planning to breastfeed their baby to participate.

    So what’s the advice for now?

    There are many other things, such as genetic and environmental factors, that may also play a role in the development of a baby’s immune system, including how their immune cells respond to food allergens. And we still have a lot to learn about what causes allergies more broadly.

    While we wait for the results of the above studies, the current advice is for mothers not to avoid any common allergy-causing foods during pregnancy and breastfeeding (unless of course they’re allergic themselves).

    The science so far suggests that if anything, exposing the baby to allergens could reduce their risk of developing allergies, rather than increase it.

    Once the baby is ready to eat solid foods, we know introducing peanuts and eggs from around six months of age makes it less likely the child will develop an allergy to these foods.

    Introducing other common allergy-causing foods in the first year of life may also be helpful, although the evidence for this is not as strong compared with peanuts and eggs.

    Once these foods have been introduced, continuing to include them in your baby’s meals regularly, at least once a week, might also make it less likely they develop an allergy to these foods.

  • Lemon Balm For Stressful Times And More

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Balm For The Mind: In More Ways Than One!

    Lemon balm(Melissa officinalis) is quite unrelated to lemons, and is actually a closer relative to mint. It does have a lemony fragrance, though!

    You’ll find it in a lot of relaxing/sleepy preparations, so…

    What does the science say?

    Relaxation

    Lemon balm has indeed been found to be a potent anti-stress herb. Laboratories that need to test anything to do with stress generally create that stress in one of two main ways:

    • If it’s not humans: a forced swimming test that’s a lot like waterboarding
    • If it is humans: cognitive tests completed under time-pressure while multitasking

    Consequently, studies that have set out to examine lemon balm’s anti-stress potential in humans, have often ended up also highlighting its potential as a cognitive enhancer, like this one in which…

    ❝Both active lemon balm treatments were generally associated with improvements in mood and/or cognitive performance❞

    ~ Dr. Anastasia Ossoukhova et al.

    Read in full: Anti-Stress Effects of Lemon Balm-Containing Foods

    And this one, which found…

    ❝The results showed that the 600-mg dose of Melissa ameliorated the negative mood effects of the DISS, with significantly increased self-ratings of calmness and reduced self-ratings of alertness.

    In addition, a significant increase in the speed of mathematical processing, with no reduction in accuracy, was observed after ingestion of the 300-mg dose.❞

    ~ Dr. Wendy Little et al.

    The appropriately named “DISS” is the Defined Intensity Stress Simulation we talked about.

    Read more: Attenuation of laboratory-induced stress in humans after acute administration of Melissa officinalis (Lemon Balm)

    Sleep

    There’s a lot less research for lemon balm’s properties in this regard than for stress/anxiety, and it’s probably because sleep studies are much more expensive than stress studies.

    It’s not for a lack of popular academic interest—for example, typing “Melissa officinalis” into PubMed (the vast library of studies we often cite from) autosuggests “Melissa officinalis sleep”. But alas, autosuggestions do not Randomized Controlled Trials make.

    There are some, but they’re often small, old, and combined with other things, like this one:

    A combination of valerian and lemon balm is effective in the treatment of restlessness and dyssomnia in children

    This is interesting, because generally speaking there is little to no evidence that valerian actually helps sleep, so if this mixture worked, we might reasonably assume it was because of the lemon balm—but there’s an outside chance it could be that it only works in the presence of valerian (unlikely, but in science we must consider all possibilities).

    Beyond that, we just have meta-reviews to work from, like this one that noted:

    ❝M. officinalis contains several phytochemicals such as phenolic acids, flavonoids, terpenoids, and many others at the basis of its pharmacological activities. Indeed, the plant can have antioxidant, anti-inflammatory, antispasmodic, antimicrobial, neuroprotective, nephroprotective, antinociceptive effects.

    Given its consolidated use, M. officinalis has also been experimented with clinical settings, demonstrating interesting properties against different human diseases, such as anxiety, sleeping difficulties, palpitation, hypertension, depression, dementia, infantile colic, bruxism, metabolic problems, Alzheimer’s disease, and sexual disorders. ❞

    ~ Dr. Cristina Quispe et al.

  • Rewire Your OCD Brain – by Dr. Catherine Pittman & Dr. William Youngs

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    OCD is just as misrepresented in popular media as many other disorders, and in this case, it’s typically not “being a neat freak” or needing to alphabetize things, so much as having uncontrollable obsessive intrusive thoughts, and often in response to those, unwanted compulsions. This can come from unchecked spiralling anxiety, and/or PTSD, for example.

    What Drs. Pittman & Young offer is an applicable set of solutions, to literally rewire the brain (insofar as synapses can be considered neural wires). Leveraging neuroplasticity to work with us rather than against us, the authors talk us through picking apart the crossed wires, and putting them back in more helpful ways.

    This is not, by the way, a book of CBT, though it does touch on that too.

    Mostly, the book explains—clearly and simply and sometimes with illustrationswhat is going wrong for us neurologically, and how to neurologically change that.

    Bottom line: whether you have OCD or suffer from anxiety or just need help dealing with obsessive thoughts, this book can help a lot in, as the title suggests, rewiring that.

  • Heart Healthy Diet Plan – by Stephen William

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    We’ve covered heart-healthy cooking books before, but variety is good, and boredom is an enemy of health, so let’s shake it up with a fresh stack of recipes!

    After a brief overview of the relevant science (which if you’re a regular 10almonds reader, probably won’t be new to you), the author takes the reader on a 28-day journey. Yes, we know the subtitle says 30 days, but unless they carefully hid the other two days somewhere we didn’t find, there are “only” 28 inside. Perhaps the publisher heard it was a month and took creative license. Or maybe there’s a different edition. Either way…

    Rather than merely giving a diet plan (though yes, he also does that), he gives a wide range of “spotlight ingredients”, such that many of the recipes, while great in and of themselves, can also be jumping-off points for those of us who like to take recipes and immediately do our own things to them.

    Each day gets a breakfast, lunch, dinner, and he also covers drinks, desserts, and such like.

    Notwithstanding the cover art being a lot of plants, the recipes are not entirely plant-based; there are a selection of fish dishes (and other seafood, e.g. shrimp) and also some dairy products (e.g. Greek yoghurt). The recipes are certainly very “plant-forward” though and many are just plants. If you’re a strict vegan though, this probably isn’t the book for you.

    Bottom line: if you’d like to cook heart-healthy but are often stuck wondering “aaah, what to cook again today?”, then this is the book to get you out of any culinary creative block!

  • LGBTQ+ People Relive Old Traumas as They Age on Their Own

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Bill Hall, 71, has been fighting for his life for 38 years. These days, he’s feeling worn out.

    Hall contracted HIV, the virus that can cause AIDS, in 1986. Since then, he’s battled depression, heart disease, diabetes, non-Hodgkin lymphoma, kidney cancer, and prostate cancer. This past year, Hall has been hospitalized five times with dangerous infections and life-threatening internal bleeding.

    But that’s only part of what Hall, a gay man, has dealt with. Hall was born into the Tlingit tribe in a small fishing village in Alaska. He was separated from his family at age 9 and sent to a government boarding school. There, he told me, he endured years of bullying and sexual abuse that “killed my spirit.”

    Because of the trauma, Hall said, he’s never been able to form an intimate relationship. He contracted HIV from anonymous sex at bath houses he used to visit. He lives alone in Seattle and has been on his own throughout his adult life.

    “It’s really difficult to maintain a positive attitude when you’re going through so much,” said Hall, who works with Native American community organizations. “You become mentally exhausted.”

    It’s a sentiment shared by many older LGBTQ+ adults — most of whom, like Hall, are trying to manage on their own.

    Of the 3 million Americans over age 50 who identify as gay, bisexual, or transgender, about twice as many are single and living alone when compared with their heterosexual counterparts, according to the National Resource Center on LGBTQ+ Aging.

    This slice of the older population is expanding rapidly. By 2030, the number of LGBTQ+ seniors is expected to double. Many won’t have partners and most won’t have children or grandchildren to help care for them, AARP research indicates.

    They face a daunting array of problems, including higher-than-usual rates of anxiety and depression, chronic stress, disability, and chronic illnesses such as heart disease, according to numerous research studies. High rates of smoking, alcohol use, and drug use — all ways people try to cope with stress — contribute to poor health.

    Keep in mind, this generation grew up at a time when every state outlawed same-sex relations and when the American Psychiatric Association identified homosexuality as a psychiatric disorder. Many were rejected by their families and their churches when they came out. Then, they endured the horrifying impact of the AIDS crisis.

    “Dozens of people were dying every day,” Hall said. “Your life becomes going to support groups, going to visit friends in the hospital, going to funerals.”

    It’s no wonder that LGBTQ+ seniors often withdraw socially and experience isolation more commonly than other older adults. “There was too much grief, too much anger, too much trauma — too many people were dying,” said Vincent Crisostomo, director of aging services for the San Francisco AIDS Foundation. “It was just too much to bear.”

    In an AARP survey of 2,200 LGBTQ+ adults 45 or older this year, 48% said they felt isolated from others and 45% reported lacking companionship. Almost 80% reported being concerned about having adequate social support as they grow older.

    Embracing aging isn’t easy for anyone, but it can be especially difficult for LGBTQ+ seniors who are long-term HIV survivors like Hall.

    Of 1.2 million people living with HIV in the United States, about half are over age 50. By 2030, that’s estimated to rise to 70%.

    Christopher Christensen, 72, of Palm Springs, California, has been HIV-positive since May 1981 and is deeply involved with local organizations serving HIV survivors. “A lot of people living with HIV never thought they’d grow old — or planned for it — because they thought they would die quickly,” Christensen said.

    Jeff Berry is executive director of the Reunion Project, an alliance of long-term HIV survivors. “Here people are who survived the AIDS epidemic, and all these years later their health issues are getting worse and they’re losing their peers again,” Berry said. “And it’s triggering this post-traumatic stress that’s been underlying for many, many years. Yes, it’s part of getting older. But it’s very, very hard.”

    Being on their own, without people who understand how the past is informing current challenges, can magnify those difficulties.

    “Not having access to supports and services that are both LGBTQ-friendly and age-friendly is a real hardship for many,” said Christina DaCosta, chief experience officer at SAGE, the nation’s largest and oldest organization for older LGBTQ+ adults.

    Diedra Nottingham, a 74-year-old gay woman, lives alone in a one-bedroom apartment in Stonewall House, an LGBTQ+-friendly elder housing complex in New York City. “I just don’t trust people,“ she said. “And I don’t want to get hurt, either, by the way people attack gay people.”

    When I first spoke to Nottingham in 2022, she described a post-traumatic-stress-type reaction to so many people dying of covid-19 and the fear of becoming infected. This was a common reaction among older people who are gay, bisexual, or transgender and who bear psychological scars from the AIDS epidemic.

    Nottingham was kicked out of her house by her mother at age 14 and spent the next four years on the streets. The only sibling she talks with regularly lives across the country in Seattle. Four partners whom she’d remained close with died in short order in 1999 and 2000, and her last partner passed away in 2003.

    When I talked to her in September, Nottingham said she was benefiting from weekly therapy sessions and time spent with a volunteer “friendly visitor” arranged by SAGE. Yet she acknowledged: “I don’t like being by myself all the time the way I am. I’m lonely.”

    Donald Bell, a 74-year-old gay Black man who is co-chair of the Illinois Commission on LGBTQ Aging, lives alone in a studio apartment in subsidized LGBTQ+-friendly senior housing in Chicago. He spent 30 years caring for two elderly parents who had serious health issues, while he was also a single father, raising two sons he adopted from a niece.

    Bell has very little money, he said, because he left work as a higher-education administrator to care for his parents. “The cost of health care bankrupted us,” he said. (According to SAGE, one-third of older LGBTQ+ adults live at or below 200% of the federal poverty level.) He has hypertension, diabetes, heart disease, and nerve damage in his feet. These days, he walks with a cane.

    To his great regret, Bell told me, he’s never had a long-term relationship. But he has several good friends in his building and in the city.

    “Of course I experience loneliness,” Bell said when we spoke in June. “But the fact that I am a Black man who has lived to 74, that I have not been destroyed, that I have the sanctity of my own life and my own person is a victory and something for which I am grateful.”

    Now he wants to be a model to younger gay men and accept aging rather than feeling stuck in the past. “My past is over,” Bell said, “and I must move on.”

  • How safe are the chemicals in sunscreen? A pharmacology expert explains

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Last week, the Therapeutic Goods Administration (TGA) released its safety review of seven active ingredients commonly used in sunscreens.

    It found five were low-risk and appropriate for use in sunscreens at their current concentrations.

    However, the TGA recommended tighter restrictions on two ingredients – homosalate and oxybenzone – to reduce how much can be used in a product. This is based on uncertainty about their potential effects on the endocrine system, which creates and releases hormones.

    This news, together with recent reports some products may have inflated their claims of SPF coverage, might make Australians worried about whether their sunscreen products are working – and safe.

    But it’s not time to abandon sunscreens. In Australia, all sunscreens must pass a strict approval process before going on the market. The TGA tests the safety and efficacy of all ingredients, and this recent review is part of the TGA’s continuing commitment to safety.

    The greatest threat sunscreen poses to Australians’ health is not using it.

    Australia has the highest incidence of melanoma and non-melanoma skin cancer worldwide, and approximately 95% of melanoma cases in Australia are linked to ultraviolet (UV) exposure.

    Still, it’s understandable people want to know what’s in their products, and any changes that might affect them. So let’s take a closer look at the safety review and what it found.

    aquaArts studio/Getty

    What are the active ingredients in sunscreen?

    There are two main types of sunscreen: physical and chemical. This is based on the different active ingredients they use.

    An active ingredient is a chemical component in a product that has an effect on the body – basically, what makes the product “work”.

    In sunscreens, this is the compound that absorbs UV rays from the Sun. The other ingredients – for example, those that give the sunscreen its smell or help the skin absorb it – are “inactive”.

    Physical sunscreens typically use minerals, such as titanium dioxide and zinc oxide, that can absorb the Sun’s rays but also reflect some of them.

    Chemical sunscreens use a variety of chemical ingredients to absorb or scatter UV light, both long wave (UVA) or short wave (UVB).

    The seven active ingredients in this review are in chemical sunscreens.

    Why did the TGA do the review?

    Our current limits for the concentrations of these chemicals in sunscreen are generally consistent with other regulatory agencies, such as the European Union and the US Food and Drug Administration.

    However, safety is an evolving subject. The TGA periodically reexamines the safety of all therapeutic goods.

    Last year, the TGA revised its method of estimating sunscreen exposure to more closely model how skin is exposed to sunscreens over time.

    This model considers how much sunscreen someone typically applies, how much skin they cover (whole body versus face and hands, or just face) and how it’s absorbed through the skin.

    Given this new model – along with changes in the EU and US approaches to sunscreen regulation – the TGA selected seven common sunscreen ingredients to investigate in depth.

    Determining what’s safe

    When evaluating whether chemicals are safe for human use, testing will often consider studies in animals – especially when there is no or limited data on humans. These animal tests are done by the manufacturers, not the TGA.

    To take into account any unforeseen sensitivity humans may have to these chemicals, a “margin of safety” is built in. This is typically a concentration 50–100 times lower than the dose at which no negative effect was seen in animals.

    The sunscreen review used a margin of safety 100 times lower than this dose as the safety threshold.

    For most of the seven investigated sunscreen chemicals, the TGA found the margin of safety was above 100.

    This means they’re considered safe and low-risk for long-term use.

    However, two ingredients, homosalate and oxybenzone, were found to be below 100. This was based on the highest estimated sunscreen exposure, applied to the body at the maximum permitted concentration: 15% for homosalate, 10% for oxybenzone.

    At lower concentrations, other uses – such as just the hands and face – could be considered low-risk for both ingredients.

    What are the health concerns?

    Homosalate and oxybenzone have low acute oral toxicity – meaning you would need to swallow a lot of it to experience toxic effects, nearly half a kilogram of these chemicals – and don’t cause irritation to eyes or skin.

    There is inconclusive evidence about oxybenzone potentially causing cancer in rats and mice – but only at concentrations to which humans will never be exposed via sunscreens.

    The key issue is whether the two ingredients affect the endocrine system.

    While effects have been seen at high concentrations in animal studies, it is not clear whether these translate to humans exposed to sunscreen levels.

    No effect has been seen in clinical studies on fertility, hormones, weight gain and, in pregnant women, fetal development.

    The TGA is being very cautious here, using a very wide margin of safety under worst-case scenarios.

    What are the recommendations?

    The TGA recommends the allowed concentration of homosalate and oxybenzone be reduced.

    But exactly how much it will be lowered is complicated, depending on whether the product is intended for adults or children, specifically for face, or the whole body, and so on.

    However, some sunscreens would need to be reformulated or warning labels placed on particular formulations. The exact changes will be decided after public consultation. Submissions close on August 12.

    What about benzophenone?

    There is also some evidence benzophenone – a chemical produced when sunscreen that contains octocrylene degrades – may cause cancer at high concentrations.

    This is based on studies in which mice and rats were fed benzophenone well above the concentration in sunscreens.

    Octocrylene degrades slowly over time to benzophenone. Heat makes it degrade faster, especially at temperatures above 40°C.

    The TGA has recommended restricting benzophenone to 0.0383% in sunscreens to ensure it remains safe during the product’s shelf life.

    The Cancer Council advises storing sunscreens below 30°C.

    The bottom line

    The proposed restrictions are very conservative, based on worst-case scenarios.

    But even in worst-case scenarios, the margin of safety for these ingredients is still below the level at which any negative effect was seen in animals.

    The threat of cancer from sun exposure is far more serious than any potential negative effect from sunscreens.

    If you do wish to avoid these chemicals before new limits are imposed, several sunscreens are available that provide high levels of protection with little or no homosalate and oxybenzone. For more information, consult product labels.
