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!

6 Daily Habits To Keep Your Brain Young & Sharp
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.
Without brain health, we do not have health. So here are six ways to keep it in order:
Food for thought
The six areas to focus on are as follows:
- Physical exercise: as we at 10almonds sometimes say, what’s good for the heart is good for the brain (because the brain is only as healthy as the circulation feeding it). For this reason, the recommendation here is for physical exercise that improves heart health—so, walking, running, swimming, dancing, etc.
- Healthy diet: shocking nobody, this is important too. Specifically, a diet rich in fruits, vegetables, and healthy proteins and fats is important—partly for the heart benefits that give indirect benefits to the brain, and partly because the brain is built of stuff and so we have to consume that stuff in order to rebuild it (omega-3s features strongly here, for instance). Remember to hydrate, too! The body can’t do anything without water.
- Good sleep: yes, the famous 7–9 hours sleep per night, and yes, even at your age, whatever that might be. This is important for memory consolidation, cell repair, toxin removal, and more. Sleep deprivation, on the other hand, leads to cognitive decline and brain shrinkage.
- Mental stimulation: ideally, engaging those parts of the brain you most wish to protect (e.g. language, memory, or whatever is most important to you).
- Social interaction: this one gets underestimated a lot, but it’s important to have meaningful conversations (not just polite smalltalk from a small menu of stock phrases), and that these should be two-way, i.e. involving both listening/reading and speaking/writing. Ideally, all four of those, which for most people means online and offline social interactions.
- Stress management: because chronic stress damages brain cells and accelerates cognitive decline, it’s important to manage that; practices like mindfulness meditation go a very long way and make a big difference.

Cupping: How It Works (And How It Doesn’t)
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.
Good Health By The Cup?
In Tuesday’s newsletter, we asked you for your opinion of cupping (the medical practice), and got the above-depicted, below-described, set of responses:
- About 40% said “It may help by improving circulation and stimulating the immune system”
- About 26% said “I have never heard of the medical practice of cupping before this”
- About 19% said “It is pseudoscience and/or placebo at best, but probably not harmful
- About 9% said “It is a good, evidence-based practice that removes toxins and stimulates health”
- About 6% said “It is a dangerous practice that often causes harm to people who need medical help”
So what does the science say?
First, a quick note for those unfamiliar with cupping: it is the practice of placing a warmed cup on the skin (open side of the cup against the skin). As the warm air inside cools, it reduces the interior air pressure, which means the cup is now (quite literally) a suction cup. This pulls the skin up into the cup a little. The end result is visually, and physiologically, the same process as what happens if someone places the nozzle of a vacuum cleaner against their skin. For that matter, there are alternative versions that simply use a pump-based suction system, instead of heated cups—but the heated cups are most traditional and seem to be most popular. See also:
National Center for Complementary and Integrative Health | Cupping
It is a dangerous practice that often causes harm to people who need medical help: True or False?
False, for any practical purposes.
- Directly, it can (and usually does) cause minor superficial harm, much like many medical treatments, wherein the benefits are considered to outweigh the harm, justifying the treatment. In the case of cupping, the minor harm is usually a little bruising, but there are other risks; see the link we gave just above.
- Indirectly, it could cause harm by emboldening a person to neglect a more impactful treatment for their ailment.
But, there’s nothing for cupping akin to the “the most common cause of death is when someone gets a vertebral artery fatally severed” of chiropractic, for example.
It is a good, evidence-based practice that removes toxins and stimulates health: True or False?
True and False in different parts. This one’s on us; we included four claims in one short line. But let’s look at them individually:
- Is it good? Well, those who like it, like it. It legitimately has some mild health benefits, and its potential for harm is quite small. We’d call this a modest good, but good nonetheless.
- Is it evidence-based? Somewhat, albeit weakly; there are some papers supporting its modest health claims, although the research is mostly only published in journals of alternative medicine, and any we found were in journals that have been described by scientists as pseudoscientific.
- Does it remove toxins? Not directly, at least. There is also a version that involves making a small hole in the skin before applying the cup, the better to draw out the toxins (called “wet cupping”). This might seem a little medieval, but this is because it is from early medieval times (wet cupping’s first recorded use being in the early 7th century). However, the body’s response to being poked, pierced, sucked, etc is to produce antibodies, and they will do their best to remove toxins. So, indirectly, there’s an argument.
- Does it stimulate health? Yes! We’ll come to that shortly. But first…
It is pseudoscience and/or placebo at best, but probably not harmful: True or False?
True in that its traditionally-proposed mechanism of action is a pseudoscience and placebo almost certainly plays a strong part, and also in that it’s generally not harmful.
On it being a pseudoscience: we’ve talked about this before, but it bears repeating; just because something’s proposed mechanism of action is pseudoscience, doesn’t necessarily mean it doesn’t work by some other mechanism of action. If you tell a small child that “eating the rainbow” will improve their health, and they believe this is some sort of magical rainbow power imbuing them with health, then the mechanism of action that they believe in is a pseudoscience, but eating a variety of colorful fruit and vegetables will still be healthy.
In the case of cupping, its proposed mechanism of action has to do withbalancing qi, yin and yang, etc (for which scientific evidence does not exist), in combination with acupuncture lore (for which some limited weak scientific evidence exists). On balancing qi, yin and yang etc, this is a lot like Europe’s historically popular humorism, which was based on the idea of balancing the four humors (blood, yellow bile, black bile, phlegm). Needless to say, humorism was not only a pseudoscience, but also eventually actively disproved with the advent of germ theory and modern medicine. Cupping therapy is not more scientifically based than humorism.
On the placebo side of things, there probably is a little more to it than that; much like with acupuncture, a lot of it may be a combination of placebo and using counter-irritation, a nerve-tricking method to use pain to reduce pain (much like pressing with one’s nail next to an insect bite).
Here’s one of the few studies we found that’s in what looks, at a glance, to be a reputable journal:
Cupping therapy and chronic back pain: systematic review and meta-analysis
It may help by improving circulation and stimulating the immune system: True or False?
True! It will improve local circulation by forcing blood into the area, and stimulate the immune system by giving it a perceived threat to fight.
Again, this can be achieved by many other means; acupuncture (or just “dry needling”, which is similar but without the traditional lore), a cold shower, and/or exercise (and for that matter, sex—which combines exercise, physiological arousal, and usually also foreign bodies to respond to) are all options that can improve circulation and stimulate the immune system.

Science of Yoga – by Ann Swanson
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.
There are a lot of yoga books out there to say “bend this way, hold this that way” and so forth, but few that really explain what is going on, how, and why. And understanding those things is of course key to motivation and adherence. So that’s what this book provides!
The book is divided into sections, and in the first part we have a tour of human anatomy and physiology. This may seem almost unrelated to yoga, but is valuable necessary-knowledge to get the most out of the next section:
The next few parts are given over to yoga asanas (stretches, positions, poses, call them what you will in English) and now we are given a clear idea of what it is doing: we get to understand exactly what’s being stretched, what blood flow is being increased and how, what organs are being settled into their correct place, and many other such things.
Importantly, this means we also understand why certain things are the way they are, and why they can’t be done in some other slightly different but perhaps superficially easier way.
The style of the book is like a school textbook, really, but without patronizing the reader. The illustrations, of which there are many, are simple enough to be clear while being detailed enough to be informative.
Bottom line: if you’re ever doing yoga at home and wondering if you should cut a certain corner, this is the book that will tell you why you shouldn’t.

Top 8 Fruits That Prevent & Kill Cancer
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.
Dr. Amy Dee, pharmacist and cancer survivor herself, lays out the best options for anticancer fruits:
The fruits
Without further ado, they are:
- Kiwi: promotes cancer cell death while sparing healthy cells
- Plums & peaches: an interesting choice to list these similar fruits together as one item, but they both also induce cell death in cancer cells while sparing healthy ones
- Dragon fruit: this does the same, while also inhibiting cancer cell growth
- Figs: these have antitumor effects specifically, while removing carcinogens too, and additionally sensitizing cancer cells to light therapy
- cranberries: disrupt cancer cell adhesion, breaking down tumors, while protecting non-cancerous cells against DNA damage
- citrus fruits: inhibit tumor growth and kill cancer cells; regular consumption is also associated with a lower cancer risk (be warned though, grapefruit interacts with some medications)
- cherries: induce cancer cell death; protect healthy cells against DNA damage
- tomatoes: don’t often make it into lists of fruits, but lycopene reduces cancer risk, and slows the growth of cancer cells (10almonds note: watermelon has more lycopene than tomatoes, and is more traditionally considered a fruit in all respects, so could have taken the spot here).
We would also argue that apricots could have had a spot on the list, both for their lycopene content (comparable to tomatoes) and their botanical (and this phytochemical) similarities to peaches and plums.
For more information on each of these (she also talks about the different polyphenols and other nutrients that constitute the active compounds delivering these anticancer effects), enjoy:

How often should you wash your sheets and towels?
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.
Everyone seems to have a different opinion when it comes to how often towels and bed sheets should be washed. While many people might wonder whether days or weeks is best, in one survey from the United Kingdom, almost half of single men reported not washing their sheets for up to four months at a time.
It’s fairly clear that four months is too long to leave it, but what is the ideal frequency?
Bed linen and towels are quite different and so should be washed at different intervals. While every week or two will generally suffice for sheets, towels are best washed every few days.
Anyway, who doesn’t love the feeling of a fresh set of sheets or the smell of a newly laundered towel?
Why you should wash towels more often
When you dry yourself, you deposit thousands of skin cells and millions of microbes onto the towel. And because you use your towel to dry yourself after a shower or bath, your towel is regularly damp.
You also deposit a hefty amount of dead skin, microbes, sweat and oils onto your sheets every night. But unless you’re a prolific night sweater, your bedding doesn’t get wet after a night’s sleep.
Towels are also made of a thicker material than sheets and therefore tend to stay damp for longer.
So what is it about the dampness that causes a problem? Wet towels are a breeding ground for bacteria and moulds. Moulds especially love damp environments. Although mould won’t necessarily be visible (you would need significant growth to be able to see it) this can lead to an unpleasant smell.
As well as odours, exposure to these microbes in your towels and sheets can cause asthma, allergic skin irritations, or other skin infections.
People don’t always agree on how often to change the sheets.
http://rawpixel.com/ShutterstockSo what’s the ideal frequency?
For bedding, it really depends on factors such as whether you have a bath or shower just before going to bed, or if you fall into bed after a long, sweaty day and have your shower in the morning. You will need to wash your sheets more regularly in the latter case. As a rule of thumb, once a week or every two weeks should be fine.
Towels should ideally be washed more regularly – perhaps every few days – while your facecloth should be cleaned after every use. Because it gets completely wet, it will be wet for a longer time, and retain more skin cells and microbes.
Wash your towels at a high temperature (for example, 65°C) as that will kill many microbes. If you are conscious of saving energy, you can use a lower temperature and add a cup of vinegar to the wash. The vinegar will kill microbes and prevent bad smells from developing.
Clean your washing machine regularly and dry the fold in the rubber after every wash, as this is another place microbes like to grow.
Smelly towels
What if you regularly wash your towels, but they still smell bad? One of the reasons for this pong could be that you’ve left them in the washing machine too long after the wash. Especially if it was a warm wash cycle, the time they’re warm and damp will allow microbes to happily grow. Under lab conditions the number of these bacteria can double every 30 minutes.
It’s important to hang your towel out to dry after use and not to leave towels in the washing machine after the cycle has finished. If possible, hang your towels and bedding out in the sun. That will dry them quickly and thoroughly and will foster that lovely fresh, clean cotton smell. Using a dryer is a good alternative if the weather is bad, but outdoors in the sun is always better if possible.
Also, even if your towel is going to be washed, don’t throw a wet towel into the laundry basket, as the damp, dirty towel will be an ideal place for microbes to breed. By the time you get to doing your washing, the towel and the other laundry around it may have acquired a bad smell. And it can be difficult to get your towels smelling fresh again.
Towels should be washed more often than sheets.
New Africa/ShutterstockWhat about ‘self-cleaning’ sheets and towels?
Some companies sell “quick-dry” towels or “self-cleaning” towels and bedding. Quick-dry towels are made from synthetic materials that are weaved in a way to allow them to dry quickly. This would help prevent the growth of microbes and the bad smells that develop when towels are damp for long periods of time.
But the notion of self-cleaning products is more complicated. Most of these products contain nanosilver or copper, antibacterial metals that kill micro-organisms. The antibacterial compounds will stop the growth of bacteria and can be useful to limit smells and reduce the frequency with which you need to clean your sheets and towels.
However, they’re not going to remove dirt like oils, skin flakes and sweat. So as much as I would love the idea of sheets and towels that clean themselves, that’s not exactly what happens.
Also, excessive use of antimicrobials such as nanosilver can lead to microbes becoming resistant to them.

Fast. Feast. Repeat – by Dr. Gin Stephens
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 intermittent fasting books before, so what makes this one different?
The title “Fast. Feast. Repeat.” doesn’t give much away; after all, we already know that that’s what intermittent fasting is.
After taking the reader though the basics of how intermittent fasting works and what it does for the body, much of the rest of the book is given over to improvements.
That’s what the real strength of this book is: ways to make intermittent fasting more efficient, including how to avoid plateaus. After all, sometimes it can seem like the only way to push further with intermittent fasting is to restrict the eating window further. Not so!
Instead, Dr. Stephens gives us ways to keep confusing our metabolism (in a good way) if, for example, we had a weight loss goal we haven’t met yet.
Best of all, this comes without actually having to eat less.
Bottom line: if you want to be in good physical health, and/but also believe that life is for living and you enjoy eating food, then this book can resolve that age-old dilemma!
