Bushfire smoke affects children differently. Here’s how to protect them

Bushfires are currently burning in Australian states including Victoria, Tasmania, Western Australia and South Australia. In some areas, fire authorities have warned residents about the presence of smoke.

Bushfire smoke is harmful to our health. Tiny particles of ash can lodge deep in the lungs.

Exposure to this type of smoke may worsen existing conditions such as asthma, and induce a range of health effects from irritation of the eyes, nose and throat to changes in the cardiovascular system.

Public health recommendations during smoke events tend to provide general advice, and don’t often include advice specifically geared at children. But children are not just little adults. They are uniquely vulnerable to environmental hazards such as bushfire smoke for a number of reasons.

Different physiology, different behaviour

Children’s lungs are still developing and maturing.

Airways are smaller in children, especially young children, which is associated with greater rates of particle deposition – when particles settle on the surfaces of the airways.

Children also breathe more air per kilogram of body weight compared with adults, and therefore inhale more polluted air relative to their size.

Further, children’s detoxification systems are still developing, so environmental toxins take longer to effectively clear from their bodies.

Meanwhile, children’s behaviour and habits may expose them to more environmental toxins than adults. For example, they tend to do more physical activity and spend more time outdoors. Higher levels of physical activity lead to more air inhaled per kilogram of body weight.

Also, a normal and important part of children’s early play is exploring their environment, including by putting things in their mouth. This can result in kids ingesting soil, dust and dirt, which often contain environmental contaminants.

For these reasons, it’s important to consider the specific needs of children when providing advice on what to do when there’s smoke in the air.

Keeping our environments healthy

The Australian government offers recommendations for minimising the health risks from exposure to bushfire smoke. The main advice includes staying indoors and keeping doors and windows closed.

This is great advice when the smoke is thick outside, but air pollutants may still accumulate inside the home. So it’s important to air your home once the smoke outside starts to clear. Take advantage of wind changes to open up and get air moving out of the house with a cross breeze.

Kids are natural scientists, so get them involved. For example, you and your child can “rate” the air each hour by looking at a landmark outside your home and rating how clearly you can see it. When you notice the haze is reducing, open up the house and clear the air.

Because air pollutants settle onto surfaces in our home and into household dust, an easy way to protect kids during smoky periods is to do a daily dust with a wet cloth and vacuum regularly. This will remove pollutants and reduce ingestion by children as they play. Frequent hand washing helps too.

Healthy bodies and minds

Research exploring the effects of bushfire smoke exposure on children’s health is sparse. However, during smoke events, we do see an increase in hospital visits for asthma, as well as children reporting irritation to their eyes, nose and throat.

If your child has asthma or another medical condition, ensure they take any prescribed medications on a regular schedule to keep their condition well controlled. This will minimise the risk of a sudden worsening of their symptoms with bushfire smoke exposure.

Make sure any action plans for symptom flare-ups are up to date, and ensure you have an adequate supply of in-date medication somewhere easy to locate and access.

Kids can get worried during bushfires, and fire emergencies have been linked with a reduction in children’s mental health. Stories such as the Birdie’s Tree books can help children understand these events do pass and people help one another in times of difficulty.

Learning more about air pollution can help too. Our group has a children’s story explaining how air pollution affects our bodies and what can help.

It’s also important for parents and caregivers not to get too stressed, as children cope better when their parents manage their own anxiety and help their children do the same. Try to strike a balance between being vigilant and staying calm.

What about masks?

N95 masks can protect the wearer from fine particles in bushfire smoke, but their use is a bit complicated when it comes to kids. Most young children won’t be able to fit properly into an N95 mask, or won’t tolerate the tight fit for long periods. Also, their smaller airways make it harder for young children to breathe through a mask.

If you choose to use an N95 mask for your children, it’s best to save them for instances when high-level outdoor exposure is unavoidable, such as if you’re going outside when the smoke is very thick.

N95 masks should be replaced after around four hours or when they become damp.

If your child has an existing heart or lung condition, consult their doctor before having them wear an N95 mask.

  • What you need to know about the new weight loss drug Zepbound

    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.

    In a recent poll, KFF found that nearly half of U.S. adults were interested in taking a weight management drug like the increasingly popular Ozempic, Wegovy, and Mounjaro. 

    “I can understand why there would be widespread interest in these medications,” says Dr. Alyssa Lampe Dominguez, an endocrinologist and clinical assistant professor at the University of Southern California. “Obesity is a chronic disease that is very difficult to treat. And a lot of the medications that we previously used weren’t as effective.”

    Now, there’s a new option available: In November 2023, the FDA approved Zepbound, another weight management medication, developed by the pharmaceutical company Eli Lilly. Zepbound is different from other drugs in many ways, including the fact that it’s proven to be the most effective option so far.

    Keep reading to find out more about Zepbound, including who can take it, its side effects, and more. 

    What is Zepbound? 

    Zepbound, one of the brand names for tirzepatide, is an injectable drug with a maximum dosage of 15 mg per week. It’s based on incretin, a hormone that’s naturally released in the gut after a meal. (Mounjaro is another brand name for tirzepatide.) 

    Tirzepatide is considered a dual agonist because it activates the two primary incretin hormones: the glucagon-like peptide-1 (GLP-1) and gastric inhibitory peptide (GIP) hormones.

    According to Dr. Katherine H. Saunders, an obesity medicine physician at Weill Cornell Medicine and co-founder of Intellihealth, tirzepatide is involved with several processes that regulate blood sugar, slow the removal of food from the stomach, and affect brain areas involved in appetite.

    This means that people taking the medication feel less hungry and get fuller faster, leading to less food intake and, ultimately, weight loss.

    How is Zepbound different from Ozempic?

    The medications are different in many ways. Ozempic and Wegovy, which are both brand names for semaglutide, only target the GLP-1 hormone. Studies have shown that Zepbound can lead to a higher percentage of total body weight loss than semaglutide medications. In addition to being more effective, there is some evidence that Zepbound is overall more tolerable than Ozempic or Wegovy. 

    “I have seen overall lower rates in severity of side effects with the tirzepatide medications. Mounjaro [tirzepatide] in particular is the one that I’ve used up until this point, but there’s a thought that the GIP component of the medication actually decreases nausea,” adds Lampe Dominguez. “Anecdotally, patients that I have switched from semaglutide or Ozempic to Mounjaro say that they have less side effects with Mounjaro.”

    How is Zepbound different from Mounjaro? 

    Zepbound and Mounjaro are the same medication—tirzepatide—but they’re approved for different conditions. Zepbound is FDA-approved for weight loss, while Mounjaro is approved for type 2 diabetes. (However, Mounjaro is also at times prescribed off-label for weight loss.) 

    What are some of Zepbound’s side effects? 

    According to the FDA, side effects include nausea, vomiting, diarrhea, constipation, stomach discomfort and pain, fatigue, and burping. See a more comprehensive list of side effects here

    Who can take Zepbound?

    Zepbound is FDA-approved for adults with obesity (a BMI of 30 or greater) or who have a BMI of 27 or greater with at least one weight-related condition, like high blood pressure, type 2 diabetes, or high cholesterol. 

    “I tend to advise patients who don’t meet those criteria to not take these medications because we really don’t know what the risks are,” says Lampe Dominguez, adding that people with lower BMI weren’t included in the medication’s studies. “We don’t know if there are specific risks to using this medication at a lower body mass index [or] if there might be some negative outcomes.”

    Both doctors agree that it’s important for people who are interested in starting any weight loss medication to talk to their doctors about the potential risks and benefits. For instance, the FDA notes that Zepbound has caused thyroid tumors in rats, and while it’s unknown if this could also happen to humans, the agency said the medication shouldn’t be used in patients with a personal or family history of medullary thyroid cancer. 

    “Zepbound is a powerful medication that can lead to severe side effects, vitamin deficiencies, a complete lack of appetite, or too much weight loss if prescribed without the appropriate personalization, education, and close monitoring,” says Saunders.

    “With all of these medications, and particularly with Zepbound, we would want to make sure that [patients] don’t have a family history of a specific type of thyroid cancer called medullary thyroid cancer,” says Lampe Dominguez.

    How long should people take Zepbound for?

    “Anti-obesity medications like Zepbound are not meant for short-term weight loss, but long-term treatment of obesity, which is a chronic disease,” explains Saunders. “We prepare our patients to be on the medication (or some type of medical obesity treatment) long term for their chronic disease, which is only controlled for the duration of time they’re being treated.”

  • 100 Things Productive People Do – by Nigel Cumberland

    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.

    This is a book of a hundred small chapters (the book is 396 pages, so 2–3 pages per chapter) which makes for a feeling of quick reading, and definitely gives an option of “light bites”, dipping into the book here and there.

    Cumberland offers a wide range of practical wisdom here, and while the book is (per the title) focused on productivity, it also includes all due weight to not burning out and/or breaking down. Because things productive people do does not, it turns out, include working themselves directly into an early grave.

    But—despite the author’s considerable and obvious starting point of social privilege—nor is this a tome of “offer your genius leadership and otherwise just coast while everyone does your work for you”, either. This is a “brass tacks” book and highly relatable whether your to-do list most prominently features “personally manage the merger of these Fortune 500 companies” or “sort out that junk in the spare room”

    Bottom line: we’d be surprised if this book with 100 pieces of advice failed to bring you enough value to more than pay for itself!

  • Protein vs Sarcopenia

    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.

    Protein vs Sarcopenia

    This is Dr. Gabrielle Lyon. A medical doctor, she’s board-certified in family medicine, and has also engaged in research and clinical practice in the fields of geriatrics and nutritional sciences.

    A quick note…

    We’re going to be talking a bit about protein metabolism today, and it’s worth noting that Dr. Lyon personally is vehemently against vegetarianism/veganism, and considers red meat to be healthy.

    Scientific consensus on the other hand, holds that vegetarianism and veganism are fine for most people if pursued in an informed and mindful fashion, that white meat and fish are also fine for most people, and red meat is simply not.

    If you’d like a recap on the science of any of that:

    Nevertheless, if we look at the science that she provides, the advice is sound when applied to protein in general and without an undue focus on red meat.

    How much protein is enough?

    In our article linked above, we gave 1–2g/kg/day

    Dr. Lyons gives the more specific 1.6g/kg/day for adults older than 40 (this is where sarcopenia often begins!) and laments that many sources offer 0.8g/kg.

    To be clear, that “per kilogram” means per kilogram of your bodyweight. For Americans, this means dividing lbs by 2.2 to get the kg figure.

    Why so much protein?

    Protein is needed to rebuild not just our muscles, but also our bones, joint tissues, and various other parts of us:

    We Are Such Stuff As Fish Are Made Of

    Additionally, our muscles themselves are important for far more than just moving us (and other things) around.

    As Dr. Lyon explains: sarcopenia, the (usually age-related) loss of muscle mass, does more than just make us frail; it also messes up our metabolism, which in turn messes up… Everything else, really. Because everything depends on that.

    This is because our muscles themselves use a lot of our energy, and/but also store energy as glycogen, so having less of them means:

    • getting a slower metabolism
    • the energy that can’t be stored in muscle tissue gets stored somewhere else (like the liver, and/or visceral fat)

    So, while for example the correlation between maintaining strong muscles and avoiding non-alcoholic fatty liver disease may not be immediately obvious, it is clear when one follows the metabolic trail to its inevitable conclusion.

    Same goes for avoiding diabetes, heart disease, and suchlike, though those things are a little more intuitive.

    How can we get so much protein?

    It can seem daunting at first to get so much protein if you’re not used to it, especially as protein is an appetite suppressant, so you’ll feel full sooner.

    It can especially seem daunting to get so much protein if you’re trying to avoid too many carbs, and here’s where Dr. Lyon’s anti-vegetarianism does have a point: it’s harder to get lean protein without meat/fish.

    That said, “harder” does not mean “impossible” and even she acknowledges that lentils are great for this.

    If you’re not vegetarian or vegan, collagen supplementation is a good way to make up any shortfall, by the way.

    And for everyone, there are protein supplements available if we want them (usually based on whey protein or soy protein)

    Anything else we need to do?

    Yes! Eating protein means nothing if you don’t do any resistance work to build and maintain muscle. This can take various forms, and Dr. Lyon recommends lifting weights and/or doing bodyweight resistance training (calisthenics, Pilates, etc).

    Here are some previous articles of ours, consistent with the above:

  • Give Your Adrenal Glands A Chance

    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.

    The Hats Of Wrath

    Your adrenal glands are two little hat-shaped glands that sit on top of your kidneys (like your kidneys are wearing them as hats, in fact).

    They produce adrenaline, as you might have guessed, and also cortisol and aldosterone, which you might or might not have known, as well as some miscellaneous corticosteroids that are beyond the scope of today’s article.

    Fun fact! For a long time, doctors thought adrenal glands were much larger than they usually are, because of learning anatomy from corpses that were dissected, but invariably the corpses were those of poor people, especially criminals, whose adrenal glands were almost always overworked and swollen.

    You don’t want yours to be like that.

    What goes wrong

    Assuming you don’t have a rare disorder like Addison’s disease (in which the adrenal glands don’t produce enough of the hormones they’re supposed to), your adrenal glands will usually not have trouble producing enough adrenaline et al.

    However, as we learned from the Victorian vagabonds, they can also have no problems producing too much—much like any organ that gets overworked, however, this has consequences.

    Hopefully you’re not living a life of stressful crime on the streets, but maybe you have other reasons your adrenal glands are working overtime, such as any source of chronic stress, bad sleep (can’t recharge without this downtime), overuse of stimulants (including caffeine and/or nicotine), and, counterintuitively, alcohol. All these things can tax the adrenal glands considerably.

    When this happens, in the extreme we can get Cushing’s syndrome, characterized by the symptoms: hypertension, cortisol-based fat distribution i.e. especially face and abdomen, weakness, fragile easily irritable skin, hair loss and/or hirsutism, paradoxically, and of course general fatigue.

    In the non-extreme, we get all the same symptoms just to a lower level, and experience what the medical profession is begging us not to call “Adrenal Fatigue Syndrome” because that’s not an official diagnosis, whereas if it gets a name then they’ll be expected to treat it.

    What keeps things going right

    Obviously, the opposite of the above, for a start. Which means:

    Manage chronic stress; see: How To Manage Chronic Stress

    Get good sleep; see: Why You Probably Need More Sleep

    Go easy on the caffeine; see: Caffeine Mythbusting

    Skip the nicotine; see: Nicotine Benefits (That We Don’t Recommend)!

    Avoid alcohol; see: How To Reduce Or Quit Alcohol

    There are specific vitamins and minerals that support adrenal health too; they are: vitamins B5, B6, B12, C, & D, and also magnesium and zinc.

    Good dietary sources of the above include green leafy things, cruciferous vegetables*, nuts and seeds, avocados, olive oil, and if you eat fish, then also fatty fish.

    In contrast, it is good to cut down (or avoid entirely) red meat and unfermented dairy.

    Want to know more?

    A large part of adrenal health is about keeping cortisol levels down generally (except: for most of us, we can have a little hormesis, as a treat), so for the rest of that you might like to read:

  • Castor Oil: All-Purpose Life-Changer, Or Snake Oil?

    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.

    As “trending” health products go, castor oil is enjoying a lot of popularity presently, lauded as a life-changing miracle-worker, and social media is abuzz with advice to put it everywhere from your eyes to your vagina.

    But:

    • what things does science actually say it’s good for,
    • what things lack evidence, and
    • what things go into the category of “wow definitely do not do that”?

    We don’t have the space to go into all of its proposed uses (there are simply far too many), but we’ll examine some common ones:

    To heal/improve the skin barrier

    Like most oils, it’s functional as a moisturizer. In particular, its high (90%!) ricinoleic fatty acid content does indeed make it good at that, and furthermore, has properties that can help reduce skin inflammation and promote wound healing:

    Bioactive polymeric formulations for wound healing ← there isn’t a conveniently quotable summary we can just grab here, but you can see the data and results, from which we can conclude:

    • formulations with ricinoleic acid (such as with castor oil) performed very well for topical anti-inflammatory purposes
    • they avoided the unwanted side effects associated with some other contenders
    • they consistently beat other preparations in the category of wound-healing

    To support hair growth and scalp health

    There is no evidence that it helps. We’d love to provide a citation for this, but it’s simply not there. There’s also no evidence that it doesn’t help. For whatever reason, despite its popularity, peer-reviewed science has simply not been done for this, or if it has, it wasn’t anywhere publicly accessible.

    It’s possible that if a person is suffering hair loss specifically as a result of prostaglandin D2 levels, that ricinoleic acid will inhibit the PGD2, reversing the hair loss, but even this is hypothetical so far, as the science is currently only at the step before that:

    In silico prediction of prostaglandin D2 synthase inhibitors from herbal constituents for the treatment of hair loss

    However, due to some interesting chemistry, the combination of castor oil and warm water can result in acute (and irreversible) hair felting, in other words, the strands of hair suddenly glue together to become one mass which then has to be cut off:

    “Castor Oil” – The Culprit of Acute Hair Felting

    👆 this is a case study, which is generally considered a low standard of evidence (compared to high-quality Randomized Controlled Trials as the highest standard of evidence), but let’s just say, this writer (hi, it’s me) isn’t risking her butt-length hair on the off-chance, and doesn’t advise you to, either. There are other hair-oils out there; argan oil is great, coconut oil is totally fine too.

    As a laxative

    This time, there’s a lot of evidence, and it’s even approved for this purpose by the FDA, but it can be a bit too good, insofar as taking too much can result in diarrhea and uncomfortable cramping (the cramps are a feature not a bug; the mechanism of action is stimulatory, i.e. it gets the intestines squeezing, but again, it can result in doing that too much for comfort):

    Castor Oil: FDA-Approved Indications

    To soothe dry eyes

    While putting oil in your eyes may seem dubious, this is another one where it actually works:

    ❝Castor oil is deemed safe and tolerable, with strong anti-microbial, anti-inflammatory, anti-nociceptive, analgesic, antioxidant, wound healing and vasoconstrictive properties.

    These can supplement deficient physiological tear film lipids, enabling enhanced lipid spreading characteristics and reducing aqueous tear evaporation.

    Studies reveal that castor oil applied topically to the ocular surface has a prolonged residence time, facilitating increased tear film lipid layer thickness, stability, improved ocular surface staining and symptoms.❞

    Source: Therapeutic potential of castor oil in managing blepharitis, meibomian gland dysfunction and dry eye

    Against candidiasis (thrush)

    We couldn’t find science for (or against) castor oil’s use against vaginal candidiasis, but here’s a study that investigated its use against oral candidiasis:

    Rosemary, Castor Oils, and Propolis Extract: Activity Against Candida Albicans and Alterations on Properties of Dental Acrylic Resins

    …in which castor oil was the only preparation that didn’t work against the yeast.

    Summary

    We left a lot unsaid today (so many proposed uses, it feels like a shame to skip them), but in few words: it’s good for skin (including wound healing) and eyes; but we’d give it a miss for hair, candidiasis, and digestive disorders.
