Stay Safe From Heat Exhaustion & Heatstroke!
For most of us, summer is upon us now. Which can be lovely… and also bring new, different health risks. Today we’re going to talk about heat exhaustion and heatstroke.
What’s the difference?
Heat exhaustion is a milder form of heatstroke, but the former can turn into the latter very quickly if left untreated.
Symptoms of heat exhaustion include:
- Headache
- Nausea
- Cold sweats
- Light-headedness
Symptoms of heatstroke include the above and also:
- Red/flushed-looking skin
- High body temperature (104ºF / 40ºC)
- Disorientation/confusion
- Accelerated heart rate

What should we do about it?
In the case of heatstroke, call 911 or the equivalent emergency number for the country where you are.
Hopefully we can avoid it getting that far, though:
Prevention first
Here are some top tips to avoid heat exhaustion and thus also avoid heatstroke. Many are common sense, but it’s easy to forget things—especially in the moment, on a hot sunny day!
- Hydrate, hydrate, hydrate
- (Non-sugary) iced teas, fruit infusions, that sort of thing are more hydrating than water alone
- Avoid alcohol
- If you really want to imbibe, rehydrate between each alcoholic drink
- Time your exercise with the heat in mind
- In other words, make any exercise session early or late in the day, not during the hottest period
- Use sunscreen
- This isn’t just for skin health (though it is important for that); it will also help keep you cooler, as it blocks the UV rays that literally cook your cells
- Keep your environment cool
- Shade is good, air conditioning / cooling fans can help.
- A wide-brimmed hat is portable shade just for you
- Wear loose, breathable clothing
- We write about health, not fashion, but: light breathable clothes that cover more of your body are generally better healthwise in this context, than minimal clothes that don’t, if you’re in the sun.
- Be aware of any medications you’re taking that will increase your sensitivity to heat.
- This includes medications that are dehydrating, and includes most anti-depressants, many anti-nausea medications, some anti-allergy medications, and more.
- Check your labels/leaflets, look up your meds online, or ask your pharmacist.
Treatment
If prevention fails, treatment is next. Again, in the case of heatstroke, it’s time for an ambulance.
If symptoms are “only” of heat exhaustion and are more mild, then:
- Move to a cooler location
- Rehydrate again
- Remove clothing that’s confining or too thick
- What does confining mean? Clothing that’s tight and may interfere with the body’s ability to lose heat.
- For example, you might want to lose your sports bra, but there is no need to lose a bikini, for instance.
- What does confining mean? Clothing that’s tight and may interfere with the body’s ability to lose heat.
- Use ice packs or towels soaked in cold water, applied to your body, especially wear circulation is easiest to affect, e.g. forehead, wrists, back of neck, under the arms, or groin.
- A cool bath or shower, or a dip in the pool may help cool you down, but only do this if there’s someone else around and you’re not too dizzy.
- This isn’t a good moment to go in the sea, no matter how refreshing it would be. You do not want to avoid heatstroke by drowning instead.
If full recovery doesn’t occur within a couple of hours, seek medical help.
Stay safe and have fun!

5 Surprising Benefits Of Exercise After 50 (More Than Just Fitness)
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.
It’s easy to want to do less as we get older, but the benefits of continuing to actively exercise, pushing oneself even just a little, can be far-reaching.
Direct and indirect benefits
As well as the obvious fitness benefits, keeping up good levels of exercise can also offer:
Healthy Skin
Exercise improves circulation, bringing growth factors (thus: regeneration, because it’s replacing cells), oxygen, and nutrients to the skin. Accordingly, it can lead to healthier, more youthful-looking skin as a low-cost alternative to a lot of skincare products. That said, it also encourages good skin habits, like daily sunscreen use.
Bone Health
Weight-bearing and resistance exercises (which between them, encompasses most forms of exercise) improve bone density. This is because physical stress signals bones to strengthen, reducing the risk of fractures. This includes activities like walking, hiking, and using resistance bands or weights. Note however that it is on a “per bone” basis. So for example, hiking will improve your lower body and spine, but do nothing for your arms. On the other hand, doing a daily groceries trip on foot, if local geography makes that practicable, can do the whole body, if one is then carrying groceries home (this writer lives about 2 miles from where she buys groceries, and does this pretty much daily).
Mental Health
Exercise, especially outdoors, has well-established positive effects on mental well-being, and can relieve stress and improve mood. As a bonus, community engagement and shared experiences can enhance mental health benefits for many people—but if you prefer it as peaceful time for yourself, that’s beneficial in its own way too!
Better Sleep
Physical activity helps promote better sleep quality, which is important for so many aspects of health—because fatiguing the body through exercise can lead to a more restful night, which is often harder to achieve with age.
Visibility and Confidence
Staying active and taking on challenges (e.g. training for some event) can boost visibility in social and family settings, countering “invisibility” often felt from midlife onwards. And even if one doesn’t do those things, exercise fosters confidence and helps people carry themselves with more self-assurance, which has a lot of knock-on benefits too.

Yes, you still need to use sunscreen, despite what you’ve heard on TikTok
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.
Summer is nearly here. But rather than getting out the sunscreen, some TikTokers are urging followers to chuck it out and go sunscreen-free.
They claim it’s healthier to forgo sunscreen to get the full benefits of sunshine.
Here’s the science really says.
Karolina Grabowska/Pexels How does sunscreen work?
Because of Australia’s extreme UV environment, most people with pale to olive skin or other risk factors for skin cancer need to protect themselves. Applying sunscreen is a key method of protecting areas not easily covered by clothes.
Sunscreen works by absorbing or scattering UV rays before they can enter your skin and damage DNA or supportive structures such as collagen.
When UV particles hit DNA, the excess energy can damage our DNA. This damage can be repaired, but if the cell divides before the mistake is fixed, it causes a mutation that can lead to skin cancers.
The energy from a particle of UV (a photon) causes DNA strands to break apart and reconnect incorrectly. This causes a bump in the DNA strand that makes it difficult to copy accurately and can introduce mutations. NASA/David Herring The most common skin cancers are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Melanoma is less common, but is the most likely to spread around the body; this process is called metastasis.
Two in three Australians will have at least one skin cancer in their lifetime, and they make up 80% of all cancers in Australia.
Around 99% of skin cancers in Australia are caused by excessive exposure to UV radiation.
Excessive exposure to UV radiation also affects the appearance of your skin. UVA rays are able to penetrate deep into the skin, where they break down supportive structures such as elastin and collagen.
This causes signs of premature ageing, such as deep wrinkling, brown or white blotches, and broken capillaries.
Sunscreen can help prevent skin cancers
Used consistently, sunscreen reduces your risk of skin cancer and slows skin ageing.
In a Queensland study, participants either used sunscreen daily for almost five years, or continued their usual use.
At the end of five years, the daily-use group had reduced their risk of squamous cell carcinoma by 40% compared to the other group.
Ten years later, the daily use group had reduced their risk of invasive melanoma by 73%
Does sunscreen block the health-promoting properties of sunlight?
The answer is a bit more complicated, and involves personalised risk versus benefit trade-offs.
First, the good news: there are many health benefits of spending time in the sun that don’t rely on exposure to UV radiation and aren’t affected by sunscreen use.
Sunscreen only filters UV rays, not all light. Ron Lach/Pexels Sunscreen only filters UV rays, not visible light or infrared light (which we feel as heat). And importantly, some of the benefits of sunlight are obtained via the eyes.
Visible light improves mood and regulates circadian rhythm (which influences your sleep-wake cycle), and probably reduces myopia (short-sightedness) in children.
Infrared light is being investigated as a treatment for several skin, neurological, psychiatric and autoimmune disorders.
So what is the benefit of exposing skin to UV radiation?
Exposing the skin to the sun produces vitamin D, which is critical for healthy bones and muscles.
Vitamin D deficiency is surprisingly common among Australians, peaking in Victoria at 49% in winter and being lowest in Queensland at 6% in summer.
Luckily, people who are careful about sun protection can avoid vitamin D deficiency by taking a supplement.
Exposing the skin to UV radiation might have benefits independent of vitamin D production, but these are not proven. It might reduce the risk of autoimmune diseases such as multiple sclerosis or cause release of a chemical that could reduce blood pressure. However, there is not enough detail about these benefits to know whether sunscreen would be a problem.
What does this mean for you?
There are some benefits of exposing the skin to UV radiation that might be blunted by sunscreen. Whether it’s worth foregoing those benefits to avoid skin cancer depends on how susceptible you are to skin cancer.
If you have pale skin or other factors that increase you risk of skin cancer, you should aim to apply sunscreen daily on all days when the UV index is forecast to reach 3.
If you have darker skin that rarely or never burns, you can go without daily sunscreen – although you will still need protection during extended times outdoors.
For now, the balance of evidence suggests it’s better for people who are susceptible to skin cancer to continue with sun protection practices, with vitamin D supplementation if needed.

As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝What’s the science on chocolate and acne? Asking for a family member❞
The science is: these two things are broadly unrelated to each other.
There was a very illustrative study done specifically for this, though!
❝65 subjects with moderate acne ate either a bar containing ten times the amount of chocolate in a typical bar, or an identical-appearing bar which contained no chocolate. Counting of all the lesions on one side of the face before and after each ingestion period indicated no difference between the bars.
Five normal subjects ingested two enriched chocolate bars daily for one month; this represented a daily addition of the diet of 1,200 calories, of which about half was vegetable fat. This excessive intake of chocolate and fat did not alter the composition or output of sebum.
A review of studies purporting to show that diets high in carbohydrate or fat stimulate sebaceous secretion and adversely affect acne vulgaris indicates that these claims are unproved.❞

Why 7 Hours Sleep Is Not Enough
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.
How Sleep-Deprived Are You, Really?
This is Dr. Matthew Walker. He’s a neuroscientist and sleep specialist, and is the Director of the Center for Human Sleep Science at UC Berkeley’s Department of Psychology. He’s also the author of the international bestseller “Why We Sleep”.
What does he want us to know?
Sleep deprivation is more serious than many people think it is. After about 16 hours without sleep, the brain begins to fail, and needs more than 7 hours of sleep to “reset” cognitive performance.
Note: note “seven or more”, but “more than seven”.
After ten days with only 7 hours sleep (per day), Dr. Walker points out, the brain is as dysfunctional as it would be after going without sleep for 24 hours.
Here’s the study that sparked a lot of Dr. Walker’s work:
Importantly, in Dr. Walker’s own words:
❝Three full nights of recovery sleep (i.e., more nights than a weekend) are insufficient to restore performance back to normal levels after a week of short sleeping❞
~ Dr. Matthew Walker
See also: Why You Probably Need More Sleep
Furthermore: the sleep-deprived mind is unaware of how sleep-deprived it is.
You know how a drunk person thinks they can drive safely? It’s like that.
You do not know how sleep-deprived you are, when you are sleep-deprived!
For example:
❝(60.7%) did not signal sleepiness before a sleep fragment occurred in at least one of the four MWT trials❞
Source: Sleepiness is not always perceived before falling asleep in healthy, sleep-deprived subjects
Sleep efficiency matters
With regard to the 7–9 hours band for optimal health, Dr. Walker points out that the sleep we’re getting is not always the sleep we think we’re getting:
❝Assuming you have a healthy sleep efficiency (85%), to sleep 9 hours in terms of duration (i.e. to be a long-sleeper), you would need to be consistently in bed for 10 hours and 36 minutes a night. ❞
~ Dr. Matthew Walker
At the bottom end of that, by the way, doing the same math: to get only the insufficient 7 hours sleep discussed earlier, a with a healthy 85% sleep efficiency, you’d need to be in bed for 8 hours and 14 minutes per night.
The unfortunate implication of this: if you are consistently in bed for 8 hours and 14 minutes (or under) per night, you are not getting enough sleep.
“But what if my sleep efficiency is higher than 85%?”
It shouldn’t be.If your sleep efficiency is higher than 85%, you are sleep-deprived and your body is having to enforce things.

The No-Nonsense Meditation Book – by Dr. Steven Laureys
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 reviewed books about meditation before, and when we review books, we try to pick ones that have something that make them stand out from the others. So, what stands out in this case?
The author is a medical doctor and neurologist, with decades of experience focusing on neuronal plasticity and multimodel neural imaging. So, a little beyond “think happy thoughts”-style woo.
The style of the book is pop-science in tone, but with a lot of hard clinical science underpinning it and referenced throughout, as one would expect of a scientist of Dr. Laurey’s stature (with hundreds of peer-reviewed papers in top-level journals).
You may be wondering: is this a “how-to” book or a “why-to” book or a “what-happens” book? It’s all three.
The “how-to” is also, as the title suggests, no-nonsense. We are talking maximum results for minimum mystery here.
Bottom line: if you’d like to be able to take up a meditative practice and know exactly what it’s doing to your brain (quietening these parts, stimulating and physically growing those parts, etc) then this is the book for you.

Cooling Bulgarian Tarator
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 “Bulgarian” qualifier is important here because the name “tarator” is used to refer to several different dishes from nearby-ish countries, and they aren’t the same. Today’s dish (a very healthy and deliciously cooling cucumber soup) isn’t well-known outside of Bulgaria, but it should be, and with your help we can share it around the world. It’s super-easy and takes only about 10 minutes to prepare:
You will need
- 1 large cucumber, cut into small (¼” x ¼”) cubes or small (1″ x ⅛”) batons (the size is important; any smaller and we lose texture; any larger and we lose the balance of the soup, and also make it very different to eat with a spoon)
- 2 cups plain unsweetened yogurt (your preference what kind; live-cultured of some kind is best, and yes, vegan is fine too)
- 1½ cup water, chilled but not icy (fridge-temperature is great)
- ½ cup chopped walnuts (substitutions are not advised; omit if allergic)
- ½ bulb garlic, minced
- 3 tbsp fresh dill, chopped
- 2 tbsp extra virgin olive oil
- 1 tsp black pepper, coarse ground
- ½ tsp MSG* or 1 tsp low-sodium salt
Method
(we suggest you read everything at least once before doing anything)
1) Mix the cucumber, garlic, 2 tbsp of the dill, oil, MSG-or-salt and pepper in a big bowl
2) Add the yogurt and mix it in too
3) Add the cold water slowly and stir thoroughly; it may take a minute to achieve smooth consistency of the liquid—it should be creamy but thin, and definitely shouldn’t stand up by itself
4) Top with the chopped nuts, and the other tbsp of dill as a garnish
5) Serve immediately, or chill in the fridge until ready to serve. It’s perfect as a breakfast or a light lunch, by the way.
Enjoy!
