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.The Conversation

  • Rice vs Buckwheat – Which is Healthier?

    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.

    Our Verdict

    When comparing rice to buckwheat, we picked the buckwheat.

    Why?

    It’s a simple one today:

    • The vitamin and mineral profiles are very similar, so neither of these are a swaying factor
    • In terms of macros, rice is higher in carbohydrates while buckwheat is higher in fiber
    • Buckwheat also has more protein, but not by much
    • Buckwheat has the lower glycemic index, and a lower insulin index, too

    While buckwheat cannot always be reasonably used as a substitute for rice (often because the texture would not work the same), in many cases it can be.

    And if you love rice, well, so do we, but variety is also the spice of life indeed, not to mention important for good health. You know that whole “eat 30 different plants per week” thing? Grains count in that tally! So substituting buckwheat in place of rice sometimes seems like a very good bet.

    Myth-Buster, Myth-Buster, Bust Us A Myth (or three!)

    Let’s can this myth for good

    People think of “canned foods” as meaning “processed foods” and therefore bad. But the reality is it’s all dependent on what’s in the can (check the ingredients!). And as for nutrients?

    Many canned fruits and vegetables contain more nutrients than fresh ones! This is because the way they’ve been stored preserves them better. For example:

    • Canned tomatoes contain more bioavailable lycopene than fresh
    • Canned spinach contains more bioavailable carotene than fresh
    • Canned corn contains more bioavailable lutein than fresh
    • The list goes on, but you get the idea!

    Many women and girls avoid doing weight-training as part of their exercise—or use only the smallest weights—to avoid “bulking up” and “looking like a man”.

    Many men, meanwhile, wish it were that easy to bulk up!

    The reality is that nobody, unless you have very rare genes, packs on a lot of muscle by accident. Even with the genes for it, it won’t happen unless you’re also eating for it!

    Resistance-based strength training (such as lifting weights), is a great way for most people to look after an important part of their long-term health: bone density!

    You can’t have strong muscles on weak bones, so strengthening the muscles cues the body to strengthen the bones. In short, your strength-training at age 45 or 55 (or earlier) could be what helps you avoid a broken hip at 65 or 75.

    We’re Not Kidding, It Really Is That Important (Read The Study Here)!

    Something doesn’t smell right about this

    There’s been a big backlash against anti-perspirants and deodorants. The popular argument is that the aluminium in them causes cancer.

    This led to many people buying “deodo-rocks”, crystal rocks that can be run under water and then rubbed on the armpits to deodorize “naturally”. But, those crystal rocks are actually alum crystals (guess what they contain…).

    The belief that deodorants cause cancer came from studies done by applying deodorant to cells (like the canine kidney cells in this study) in petri dishes. So, assuming you don’t cut out your kidney and then spray it directly with the deodorant, the jury is still out!

    A more recent systematic review sorted out quite clearly the ways in which aluminium was, or was not, harmful, and said:

    ❝Neither is there clear evidence to show use of Al-containing underarm antiperspirants or cosmetics increases the risk of Alzheimer’s Disease or breast cancer. Metallic Al, its oxides, and common Al salts have not been shown to be either genotoxic or carcinogenic.❞

    …but also says that you should avoid eating aluminium while pregnant or breastfeeding. We hope you can resist the urge.

  • Egg Whites vs Whole Eggs – Which is Healthier?

    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.

    Our Verdict

    When comparing egg whites to whole eggs, we picked the whole eggs.

    Why?

    Egg whites are mostly protein. Egg yolks are mostly fat, with some protein.

    However, fat ≠ bad, and the yolk is also where the choline is stored, which itself (as well as its benefits for your brain) will tend to reduce fat storage in the body.

    Furthermore, the yolk contains an assortment of vitamins, minerals, and essential amino acids. After all, the yolk is there specifically to contain everything needed to turn a cluster of cells into a small bird.

  • Body Image Dissatisfaction/Appreciation Across The Ages

    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.

    Every second news article about body image issues is talking about teens and social media use, but science tells a different story.

    A large (n=1,327) study of people of mixed genders aged 16–88 examined matters relating to people’s body image, expecting…

    ❝We hypothesized that body dissatisfaction and importance of appearance would be higher in women than in men, that body dissatisfaction would remain stable across age in women, and that importance of appearance would be lower in older women compared to younger women. Body appreciation was predicted to be higher in men than in women.❞

    As they discovered, only half of that turned out to be true:

    ❝In line with our hypotheses, body dissatisfaction was higher in women than in men and was unaffected by age in women, and importance of appearance was higher in women than in men.

    However, only in men did age predict a lower level of the importance of appearance. Compared to men, women stated that they would invest more hours of their lives to achieve their ideal appearance.

    Contrary to our assumption, body appreciation improved and was higher in women across all ages than in men.❞

    You can read the study in full here:

    Body Dissatisfaction, Importance of Appearance, and Body Appreciation in Men and Women Over the Lifespan

    That’s a lot of information, and we don’t have the space to go into all parts of it here, fascinating as that would be. So we’re going to put two pieces of information (from the above) next to each other:

    • body dissatisfaction was higher in women than in men and was unaffected by age in women
    • body appreciation improved and was higher in women across all ages than in men

    …and resolve this apparent paradox.

    Dissatisfied appreciation

    How is it that women are both more dissatisfied with, and yet also more appreciative of, their bodies?

    The answer is that we can have positive and negative feelings about the same thing, without them cancelling each other out. In short, simply, feeling more feelings about it.

    Whether the gender-related disparity in this case comes more from hormones or society could be vigorously debated, but chances are, it’s both. And, for our gentleman-readers, note that the principle still applies to you, even if scaled down on average.

    Call to action:

    • be aware of the negative feelings of body dissatisfaction
    • focus on the positive feelings of body appreciation

    While in theory both could motivate us to action, in reality, the former will tend to inform us (about what we might wish to change), while the latter will actually motivate us in a useful way (to do something positive about it).

    This is because the negative feelings about body image tend to be largely based in shame, and shame is a useless motivator (i.e., it simply doesn’t work) when it comes to taking positive actions:

    Why Shame Only Works Negatively

    You can’t hate yourself into a body you love

    That may sound like a wishy-washy platitude, but given the evidence on how shame works (and doesn’t), it’s true.

    Instead, once you’ve identified the things about your body with which you’re dissatisfied, you can then assess:

    • what can reasonably be changed
    • whether it is important enough to you to change it
    • how to go about usefully changing it

    While weight issues are perhaps the most commonly-discussed body image consideration, to the point that often all others get forgotten, let’s look at something that’s generally more specific to adults, and also a very common cause of distress for women and men alike: hair loss/thinning.

    If your hair is just starting to thin and fall, then if this bothers you, there’s a lot that can be done about it quite easily, but (and this is important) you have to love yourself enough to actually do it. Merely feeling miserable about it, and perhaps like you don’t deserve better, or that it is somehow a personal failing on your part, will not help.

    If your hair has been gone for years, then chances are you’ve made your peace with this by now, and might not even take it back if a fairy godmother came along and offered to restore it magically. On the other hand, let’s say that you’re just coming out the other end of a 10-year-long depression, and perhaps you let a lot of things go that you now wish you hadn’t, and maybe your hair is one of them. In this case, now you need to decide whether getting implants (likely the only solution at this late stage) is worth it.

    Note that in both cases, whatever the starting point and whether the path ahead is easy or hard, the person who has dissatisfaction and/but still values themself and their body will get what they need.

    In contrast, the person who has dissatisfaction and does not value themself and their body, will languish.

    The person without dissatisfaction, of course, probably already has what they need.

    In short: identification of dissatisfaction + love and appreciation of oneself and one’s body → motivation to usefully take action (out of love, not hate)

    Now, dear reader, apply the same thinking to whatever body image issues you may have, and take it from there!

    Embodiment

    A quick note in closing: if you are a person with no body dissatisfactions, there are two main possible reasons:

    • You are genuinely happy with your body in all respects. Congratulations!
    • You have disassociated from your body to such an extent that it’s become a mere vehicle to you and you don’t care about it.

    This latter may seem like a Zen-level win, but in fact it’s a warning sign for depression, so please do examine that even if you don’t “feel” depressed (depression is often characterized by a lack of feelings), perhaps by taking the (very quick) free PHQ9 Test ← under 2 minutes; immediate results; industry-standard diagnostic tool

    Take care!

    We’ve written before about Dr. Seeman’s method for robust health at all ages, focussing on:

    • Nutrition
    • Movement
    • Sleep
    • Mindset
    • Environment

    In this book, she expands on these things far more than we have room to in our little newsletter, including (importantly!) how each interplays with the others. She also follows up with an invitation to take the “Hard to Kill 30-Day Challenge”.

    That said, in the category of criticism, it’s only 152 pages, and she takes some of that to advertise her online services in an effort to upsell the reader.

    Nevertheless, there’s a lot of worth in the book itself, and the writing style is certainly easy-reading and compelling.

    Bottom line: this book is half instructional, half motivational, and covers some very important areas of health.

  • Prolonged Grief: A New Mental Disorder?

    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 issue is not whether certain mental conditions are real—they are. It is how we conceptualize them and what we think treating them requires.

    The latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) features a new diagnosis: prolonged grief disorder—used for those who, a year after a loss, still remain incapacitated by it. This addition follows more than a decade of debate. Supporters argued that the addition enables clinicians to provide much-needed help to those afflicted by what one might simply consider a too much of grief, whereas opponents insisted that one mustn’t unduly pathologize grief and reject an increasingly medicalized approach to a condition that they considered part of a normal process of dealing with loss—a process which in some simply takes longer than in others.    

    By including a condition in a professional classification system, we collectively recognize it as real. Recognizing hitherto unnamed conditions can help remove certain kinds of disadvantages. Miranda Fricker emphasizes this in her discussion of what she dubs hermeneutic injustice: a specific sort of epistemic injustice that affects persons in their capacity as knowers1. Creating terms like ‘post-natal depression’ and ‘sexual harassment’, Fricker argues, filled lacunae in the collectively available hermeneutic resources that existed where names for distinctive kinds of social experience should have been. The absence of such resources, Fricker holds, put those who suffered from such experiences at an epistemic disadvantage: they lacked the words to talk about them, understand them, and articulate how they were wronged. Simultaneously, such absences prevented wrong-doers from properly understanding and facing the harm they were inflicting—e.g. those who would ridicule or scold mothers of newborns for not being happier or those who would either actively engage in sexual harassment or (knowingly or not) support the societal structures that helped make it seem as if it was something women just had to put up with. 

    For Fricker, the hermeneutical disadvantage faced by those who suffer from an as-of-yet ill-understood and largely undiagnosed medical condition is not an epistemic injustice. Those so disadvantaged are not excluded from full participation in hermeneutic practices, or at least not through mechanisms of social coercion that arise due to some structural identity prejudice. They are not, in other words, hermeneutically marginalized, which for Fricker, is an essential characteristic of epistemic injustice. Instead, their situation is simply one of “circumstantial epistemic bad luck”2. Still, Fricker, too, can agree that providing labels for ill-understood conditions is valuable. Naming a condition helps raise awareness of it, makes it discursively available and, thus, a possible object of knowledge and understanding. This, in turn, can enable those afflicted by it to understand their experience and give those who care about them another way of nudging them into seeking help. 

    Surely, if adding prolonged grief disorder to the DSM-5 were merely a matter of recognizing the condition and of facilitating assistance, nobody should have any qualms with it. However, the addition also turns intense grief into a mental disorder—something for whose treatment insurance companies can be billed. With this, significant forces of interest enter the scene. The DSM-5, recall, is mainly consulted by psychiatrists. In contrast to talk-therapists like psychotherapists or psychoanalysts, psychiatrists constitute a highly medicalized profession, in which symptoms—clustered together as syndromes or disorders—are frequently taken to require drugs to treat them. Adding prolonged grief disorder thus heralds the advent of research into various drug-based grief therapies. Ellen Barry of the New York Times confirms this: “naltrexone, a drug used to help treat addiction,” she reports, “is currently in clinical trials as a form of grief therapy”, and we are likely to see a “competition for approval of medicines by the Food and Drug Administration.”3

    Adding diagnoses to the DSM-5 creates financial incentives for players in the pharmaceutical industry to develop drugs advertised as providing relief to those so diagnosed. Surely, for various conditions, providing drug-induced relief from severe symptoms is useful, even necessary to enable patients to return to normal levels of functioning. But while drugs may help suppress feelings associated with intense grief, they cannot remove the grief. If all mental illnesses were brain diseases, they might be removed by adhering to some drug regimen or other. Note, however, that ‘mental illness’ is a metaphor that carries the implicit suggestion that just like physical illnesses, mental afflictions, too, are curable by providing the right kind of physical treatment. Unsurprisingly, this metaphor is embraced by those who stand to massively benefit from what profits they may reap from selling a plethora of drugs to those diagnosed with any of what seems like an ever-increasing number of mental disorders. But metaphors have limits. Lou Marinoff, a proponent of philosophical counselling, puts the point aptly:

    Those who are dysfunctional by reason of physical illness entirely beyond their control—such as manic-depressives—are helped by medication. For handling that kind of problem, make your first stop a psychiatrist’s office. But if your problem is about identity or values or ethics, your worst bet is to let someone reify a mental illness and write a prescription. There is no pill that will make you find yourself, achieve your goals, or do the right thing.

    Much more could be said about the differences between psychotherapy, psychiatry, and the newcomer in the field: philosophical counselling. Interested readers may benefit from consulting Marinoff’s work. Written in a provocative, sometimes alarmist style, it is both entertaining and—if taken with a substantial grain of salt—frequently insightful. My own view is this: from Fricker’s work, we can extract reasons to side with the proponents of adding prolonged grief disorder to the DSM-5. Creating hermeneutic resources that allow us to help raise awareness, promote understanding, and facilitate assistance is commendable. If the addition achieves that, we should welcome it. And yet, one may indeed worry that practitioners are too eager to move from the recognition of a mental condition to the implementation of therapeutic interventions that are based on the assumption that such afflictions must be understood on the model of physical disease. The issue is not whether certain mental conditions are real—they are. It is how we conceptualize them and what we think treating them requires.

    No doubt, grief manifests physically. It is, however, not primarily a physical condition—let alone a brain disease. Grief is a distinctive mental condition. Apart from bouts of sadness, its symptoms typically include the loss of orientation or a sense of meaning. To overcome grief, we must come to terms with who we are or can be without the loved one’s physical presence in our life. We may need to reinvent ourselves, figure out how to be better again and whence to derive a new purpose. What is at stake is our sense of identity, our self-worth, and, ultimately, our happiness. Thinking that such issues are best addressed by popping pills puts us on a dangerous path, leading perhaps towards the kind of dystopian society Aldous Huxley imagined in his 1932 novel Brave New World. It does little to help us understand, let alone address, the moral and broader philosophical issues that trouble the bereaved and that lie at the root not just of prolonged grief but, arguably, of many so-called mental illnesses.
