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.
Our team is currently recruiting for a study exploring the effects of bushfire smoke in children. If you live in south east Queensland and are interested in participating in the event of a bushfire or hazard reduction burn near your home, please express your interest here.

Neurotransmitter Cheatsheet
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.
Which Neurotransmitter?
There are a lot of neurotransmitters that are important for good mental health (and, by way of knock-on effects, physical health).
However, when pop-science headlines refer to them as “feel-good chemicals” (yes but which one?!) or “the love molecule” (yes but which one?!) or other such vague names when referring to a specific neurotransmitter, it’s easy to get them mixed up.
So today we’re going to do a little disambiguation of some of the main mood-related neurotransmitters (there are many more, but we only have so much room), and what things we can do to help manage them.
Dopamine
This one predominantly regulates reward responses, though it’s also necessary for critical path analysis (e.g. planning), language faculties, and motor functions. It makes us feel happy, motivated, and awake.
To have more:
- eat foods that are rich in dopamine or its precursors such as tyrosine (bananas and almonds are great)
- do things that you find rewarding
Downsides: is instrumental in most addictions, and also too much can result in psychosis. For most people, that level of “too much” isn’t obtainable due to the homeostatic system, however.
See also: Rebalancing Dopamine (Without “Dopamine Fasting”)
Serotonin
This one predominantly helps regulate our circadian rhythm. It also makes us feel happy, calm, and awake.
To have more:
- get more sunlight, or if the light must be artificial, then (ideally) full-spectrum light, or (if it’s what’s available) blue light
- spend time in nature; we are hardwired to feel happy in the environments in which we evolved, which for most of human history was large open grassy expanses with occasional trees (however, for modern purposes, a park or appropriate garden will suffice).
Downsides: this is what keeps us awake at night if we had too much light before bed, and also too much serotonin can result in (potentially fatal) serotonin syndrome. Most people can’t get that much serotonin due to our homeostatic system, but some drugs can force it upon us.
See also: Seasonal Affective Disorder Strategies
Oxytocin
This one predominantly helps us connect to others on an emotional level. It also makes us feel happy, calm, and relaxed.
To have more:
- hug a loved one (or even just think about doing so, if they’re not available)
- look at pictures/videos of cute puppies, kittens, and the like—this triggers a similar response
Downsides: negligible. Socially speaking, it can cause us to drop our guard, most for most people most of the time, this is not a problem. It can also reduce sexual desire—it’s in large part responsible for the peaceful lulled state post-orgasm. It’s not responsible for the sleepiness in men though; that’s mostly prolactin.
See also: Only One Kind Of Relationship Promotes Longevity This Much!
Adrenaline
This one predominantly affects our sympathetic nervous system; it elevates heart rate, blood pressure, and other similar functions. It makes us feel alert, ready for action, and energized.
To have more:
- listen to a “power anthem” piece of music. What it is can depend on your musical tastes; whatever gets you riled up in an empowering way.
- engage in something competitive that you feel strongly about while doing it—or by the same mechanism, a solitary activity where the stakes feel high even if it’s actually quite safe (e.g. watching a thriller or a horror movie, if that’s your thing).
Downsides: its effects are not sustainable, and (in cases of chronic stress) the body will try to sustain them anyway, which has a deleterious effect. Because adrenaline and cortisol are closely linked, chronically high adrenal action will tend to mean chronically high cortisol also.
See also: Lower Your Cortisol! (Here’s Why & How)
Some final words
You’ll notice that in none of the “how to have more” did we mention drugs. That’s because:
- a drug-free approach is generally the best thing to try first, at the very least
- there are simply a lot of drugs to affect each one (or more), and talking about them would require talking about each drug in some detail.

The Fruit That Can Specifically Reduce Belly Fat

Gambooge: Game-Changer Or Gamble?
The gambooge, also called the gummi-gutta, whence its botanical name Garcinia gummi-gutta (formerly Gardinia cambogia), is also known as the Malabar tamarind, and it even got an English name, the brindle berry.
It’s a fruit that looks like a small pale yellow pumpkin in shape, but it grows on trees and has a taste so sour, that it’s usually used only in cooking, and not eaten raw
which makes this writer really want to try it raw now.Its active phytochemical compound hydroxycitric acid (HCA) rose to popularity as a supplement in the US based on a paid recommendation from Dr. Oz, and then became a controversy as supplements associated with it, were in turn associated with hepatotoxicity (more on this in the “Is it safe?” section below).
What do people use it for?
Simply put: it’s a weight loss supplement.
Less simply put: least interestingly, it’s a mild appetite suppressant:
Safety and mechanism of appetite suppression by a novel hydroxycitric acid extract (HCA-SX) ← this talks more about the biochemistry, but isn’t a human study. Human studies have been small and with mixed results. It seems likely that (as in the rat studies discussed above) the mechanism of action is largely about increasing serotonin, which itself is a well-established appetite suppressant. Therefore, the results will depend somewhat on a person’s brain’s serotonergic system.
We’ll revisit that later, but first let’s look at…
Even less simply put: its other mechanism of action is much more interesting; it actually blocks the production of fat (especially: visceral fat) in the body, by inhibiting citrate lyase, which enzyme plays a significant role in fat production:
Effects of (−)-hydroxycitrate on net fat synthesis as de novo lipogenesis
More illustratively, here’s another study, which found:
❝G cambogia reduced abdominal fat accumulation in subjects, regardless of sex, who had the visceral fat accumulation type of obesity. No rebound effect was observed.
It is therefore expected that G cambogia may be useful for the prevention and reduction of accumulation of visceral fat. ❞
~ Dr. Norihiro Shigematsu et al.
As to why this is particularly important, and far more important than mere fat loss in general, see our previous main feature:
Visceral Belly Fat (And How To Lose It)
Is it safe?
It has shown a good safety profile up to large doses (2.8g/day):
Evaluation of the safety and efficacy of hydroxycitric acid or Garcinia cambogia extracts in humans
There have been some fears about hepatotoxicity, but they appear to be unfounded, and based on products that did not, in fact, contain HCA (and were merely sold by a company that used a similar name in their marketing):
No evidence demonstrating hepatotoxicity associated with hydroxycitric acid
However, as it has a serotoninergic effect, it could cause problems for anyone at risk of serotonin syndrome, which means caution is advisable if you are taking SSRIs (which reduce the rate at which the brain can scrub serotonin, with the usually laudable goal of having more serotonin in the brain—but it is possible to have too much of a good thing, and serotonin syndrome isn’t fun).
As ever, do check with your pharmacist and/or doctor, to be sure, since they can advise with regard to your specific situation and any medications you may be taking.

Why Going Gluten-Free Could Be A Bad Idea
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.
Is A Gluten-Free Diet Right For You?
This is Rachel Begun, MS, RD. She’s a nutritionist who, since her own diagnosis with Celiac disease, has shifted her career into a position of educating the public (and correcting misconceptions) about gluten sensitivity, wheat allergy, and Celiac disease. In short, the whole “gluten-free” field.
First, a quick recap
We’ve written on this topic ourselves before; here’s what we had to say:
On “Everyone should go gluten-free”
Some people who have gone gluten-free are very evangelical about the lifestyle change, and will advise everyone that it will make them lose weight, have clearer skin, more energy, and sing well, too. Ok, maybe not the last one, but you get the idea—a dietary change gets seen as a cure-all.
And for some people, it can indeed make a huge difference!
Begun urges us to have a dose of level-headedness in our approach, though.
Specifically, she advises:
- Don’t ignore symptoms, and/but…
- Don’t self-diagnose
- Don’t just quit gluten
One problem with self-diagnosis is that we can easily be wrong:
But why is that a problem? Surely there’s not a health risk in skipping the gluten just to be on the safe side? As it turns out, there actually is:
If we self-diagnose incorrectly, Begun points out, we can miss the actual cause of the symptoms, and by cheerfully proclaiming “I’m allergic to gluten” or such, a case of endometriosis, or Hashimoto’s, or something else entirely, might go undiagnosed and thus untreated.
“Oh, I feel terrible today, there must have been some cross-contamination in my food” when in fact, it’s an undiagnosed lupus flare-up, that kind of thing.
Similarly, just quitting gluten “to be on the safe side” can mask a different problem, if wheat consumption (for example) contributed to, but did not cause, some ailment.
In other words: it could reduce your undesired symptoms, but in so doing, leave a more serious problem unknown.
Instead…
If you suspect you might have a gluten sensitivity, a wheat allergy, or even Celiac disease, get yourself tested, and take professional advice on proceeding from there.
How? Your physician should be able to order the tests for you.
You can also check out resources available here:

❝Does anything actually get rid of cellulite? Nothing seems to❞
Let’s get the bad news over with in one go:
Nothing (that the scientific world currently knows of) can get rid of cellulite permanently, nor completely guard against it proactively. Which, given that it affects up to 98% of women to some degree, and often shows up not long after puberty (though it can appear at any time and often increases later in life), any pre-emptive health regime would need to be started as a child in any case.
As with many things that predominantly affect women, the world of medicine isn’t entirely sure what causes it, let alone how to effectively treat it.
Obviously hormones are implicated, namely estrogen.
Obviously adiposity is implicated, because one can’t have dimples in one’s fat if one doesn’t have enough fat to dimple.
Other hypothesized contributory factors include genetics, poor diet, inactivity, unhealthy lifestyle (in ways not previously mentioned, e.g. use of alcohol, tobacco, etc), accumulated toxins, and pregnancy.
Here’s an old paper (from 2004); today’s reviews say pretty much the same thing, but we love how succinctly (albeit, somewhat depressingly) this abstract states how little we know and how little we can do:
Cellulite: a review of its physiology and treatment
However, all is not lost!
There are some things that can affect how much cellulite we get, and there are some things that can reduce it, and even some things that can get rid of it completely—albeit temporarily.
First, a quick refresher on what it actually is, physiologically speaking: cellulite occurs when connective tissue bands pull the skin down in places, where fat tissue has been able to squeeze through. One of the reasons it is hypothesized women get this more than men is because our fat is not merely different in distribution and overall percentage, but also in how the fat cells stack up; we generally have have of a vertical stacking structure going on, while men generally have a more horizontal structure. This means that it can be easier for ours to get moved about differently, causing the connective tissue to pull on the skin unevenly in places.
With that in mind…
Prevention is, as we say, probably impossible if your body is running on estrogen. However, those contributory factors we mentioned above? Most of those are modifiable, including these things that it is hypothesized can reduce it:
Diet: as it seems to be worsened by inflammation (what isn’t?), an anti-inflammatory diet is recommended.
Exercise: there are three things here: 1) exercises to improve circulation and thus the body’s ability to sort things out by itself 2) HIIT exercise to reduce body fat percentage, if one has a high enough starting body fat percentage for that to be a healthy goal 3) mobility exercises, to ensure our connective tissues are the right amount of mobile.
Creams and lotions
These reduce the superficial appearance of cellulite, without actually treating the thing itself. Mostly they are caffeine-based, which when used topically increases blood flow and works as a local diuretic, reducing the water content of the fat cells, diminishing the appearance of the cellulite by making each fat cell physically smaller (while still containing the same amount of fat, and it’ll bounce back in size as soon as the body can restore osmotic balance).
Medical procedures
There are too many of these to discuss them all separately, but they all work on the principle of breaking up the tough bands of connective tissue to eliminate the dimpling of cellulite.
The methods they use vary from ultrasound to cryolipolysis to lasers to “vacuum-assisted precise tissue release”, which involves a suction pump and a multipronged robotic assembly with needles to administer anaesthetic as it goes and small blades to cut the connective tissues under the skin:
Tissue Stabilized–Guided Subcision for the Treatment of Cellulite
That last one definitely sounds like the least fun, but it’s also the only one that doesn’t take months to maybe see results.
Cellulite can and almost certainly will come back after all of these.
Home remedies
Aside from at-home versions of the above (not the robots with vacuum pumps and needles and microblades, hopefully, but for example homemade caffeine creams), and of course diet and exercise which can be considered “home remedies”, there are two more things worth mentioning:
Dry brushing: using a body brush to, as the name suggests, simply brush one’s skin. The “dry” aspect here is simply that it’s not done in the bath or shower; it’s done while dry. It can improve local circulation of blood and lymph, allowing for better detoxification and redistribution of needed bodily resources.
Here’s an example dry brushing body brush on Amazon; this writer has one and hates it, but I’ve also tried with other kinds of brush and hate them too, so it seems to be a me thing rather than a brush thing, and I have desisted in trying, now. Maybe you will like it better; many people do.
Self-massage: or massage by someone else, if that’s an option for you and you prefer. In this case, it works by a different mechanism than dry brushing; this time it’s working by the same principle as the medical techniques described in the previous section; it’s physically breaking down the toughened bits of connective tissue.
Here’s an example wooden massage roller on Amazon; this writer has one and loves it; it’s sooooooo good. I got it as a matter of general maintenance for my fascia, but it’s also very good if I get a muscular pain now and again. As for cellulite, I personally get just a little cellulite sometimes (in the backs of my thighs), and whenever I use this regularly, it goes away for at least a while.
A quick note in closing
Cellulite is normal for women and is not unhealthy. Much like gray hair for example, it’s something that can be increased by poor health, but the thing itself isn’t intrinsically unhealthy, and most of us get it to some degree at some point.
Nevertheless, aesthetic factors can also have a role to play in mental health, and we tend to feel best when we like the way our body looks. If for you that means wanting less/no cellulite, then the above are some ways towards that.
As a bonus, most of the nonmedical options are directly good for the physical health anyway, so doing them is of course good.
In particular that last one (the wooden massage roller), because that connective tissue we talked about? It matters for a lot more than just cellulite, and is heavily implicated in a lot of kinds of chronic pain, so it pays to keep it in good health:
Fascia: Why (And How) You Should Take Care Of Yours
(that article, also written by this same writer by the way, suggests a vibrating foam roller—those are very popular; I just really love my wooden one, and find it more effective)
Take care!

Coenzyme Q10 From Foods & Supplements
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.
Coenzyme Q10 and the difference it makes
Coenzyme Q10, often abbreviated to CoQ10, is a popular supplement, and is often one of the more expensive supplements that’s commonly found on supermarket shelves as opposed to having to go to more specialist stores or looking online.
What is it?
It’s a compound naturally made in the human body and stored in mitochondria. Now, everyone remembers the main job of mitochondria (producing energy), but they also protect cells from oxidative stress, among other things. In other words, aging.
Like many things, CoQ10 production slows as we age. So after a certain age, often around 45 but lifestyle factors can push it either way, it can start to make sense to supplement.
Does it work?
The short answer is “yes”, though we’ll do a quick breakdown of some main benefits, and studies for such, before moving on.
First, do bear in mind that CoQ10 comes in two main forms, ubiquinol and ubiquinone.
Ubiquinol is much more easily-used by the body, so that’s the one you want. Here be science:
What is it good for?
Benefits include:
- Against aging
- Against skin cancer
- Against breast cancer
- Against prostate cancer
- Against heart failure
- Against obesity
- Against diabetes
- Against Alzheimer’s
- Against Parkinson’s
Can we get it from foods?
Yes, and it’s equally well-absorbed through foods or supplementation, so feel free to go with whichever is more convenient for you.
Read: Intestinal absorption of coenzyme Q10 administered in a meal or as capsules to healthy subjects
If you do want to get it from food, you can get it from many places:
- Organ meats: the top source, though many don’t want to eat them, either because they don’t like them or some of us just don’t eat meat. If you do, though, top choices include the heart, liver, and kidneys.
- Fatty fish: sardines are up top, along with mackerel, herring, and trout
- Vegetables: leafy greens, and cruciferous vegetables e.g. cauliflower, broccoli, sprouts
- Legumes: for example soy, lentils, peanuts
- Nuts and seeds: pistachios come up top; sesame seeds are great too
- Fruit: strawberries come up top; oranges are great too
If supplementing, how much is good?
Most studies have used doses in the 100mg–200mg (per day) range.
However, it’s also been found to be safe at 1200mg (per day), for example in this high-quality study that found that higher doses resulted in greater benefit, in patients with early Parkinson’s Disease:
Effects of coenzyme Q10 in early Parkinson disease: evidence of slowing of the functional decline
Wondering where you can get it?
We don’t sell it (or anything else for that matter), and you can probably find it in your local supermarket or health food store. However, if you’d like to buy it online, here’s an example product on Amazon
