Sleep is a largely neglected part of health for most people. Compared to factors like food and exercise, it’s something that experientially we’re mostly not present for! Little wonder then that we also often feel like it’s outside of our control.
While Dr. Wiseman does cover the usual advices with regard to getting good sleep, this book has a lot more than that.
Assuming that they go beyond the above, resources about sleep can usually be divided into one of two categories:
- Hard science: lots about brainwaves, sleep phases, circadian rhythms, melatonin production, etc… But nothing very inspiring!
- Fantastical whimsy: lots about dreams, spiritualism, and not a scientific source to be found… Nothing very concrete!
This book does better.
We get the science and the wonder. When it comes to lucid dreaming, sleep-learning, sleep hypnosis, or a miraculously reduced need for sleep, everything comes with copious scientific sources or not at all. Dr. Wiseman is well-known in his field for brining scientific skepticism to paranormal claims, by the way—so it’s nice to read how he can do this without losing his sense of wonder. Think of him as the Carl Sagan of sleep, perhaps.
Style-wise, the book is pop-science and easy-reading. Unsurprising, for a professional public educator and science-popularizer.
Structurally, the main part of the book is divided into lessons. Each of these come with background science and principles first, then a problem that we might want to solve, then exercises to do, to get the thing we want. It’s at once a textbook and an instruction manual.
Bottom line: this is a very inspiring book with a lot of science. Whether you’re looking to measurably boost your working memory or heal trauma through dreams, this book has everything.

Capsaicin For Weight Loss And Against Inflammation
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.
Capsaicin’s Hot Benefits
Capsaicin, the compound in hot peppers that makes them spicy, is a chemical irritant and a neurotoxin. However, humans being humans, we decided to eat them for fun.
In contrast to many other ways in which humans recreationally enjoy things that are objectively poisonous, consuming capsaicin (in moderation) is considered to have health benefits, such as aiding weight loss (by boosting metabolism) and reducing inflammation.
Let’s see what the science says…
First: is it safe?
Capsaicin is classified as “Generally Recognized As Safe”. That said, the same mechanism that causes them to boost metabolism, does increase blood pressure:
Mechanisms underlying the hypertensive response induced by capsaicin
If you are in good cardiovascular health, this increase should be slight and not pose any threat, unless for example you enter a chili-eating contest when not acclimated to such:
Capsaicin and arterial hypertensive crisis
As ever, if unsure, do check with your doctor first, especially if you are taking any blood pressure medications, or otherwise have known blood pressure issues.
Does it really boost metabolism?
It certainly does; it works by increasing oxygen consumption and raising body temperature, both of which mean more calories will be burned for the same amount of work:
Dietary capsaicin and its anti-obesity potency: from mechanism to clinical implications
This means, of course, that chili peppers enjoy the status of being functionally a “negative calorie” food, and a top-tier one at that:
Chili pepper as a body weight-loss food
Here’s a good quality study that showed a statistically significant* fat loss improvement over placebo:
*To put it in numbers, the benefit was:
- 5.91 percentage points lower body fat percentage than placebo
- 6.68 percentage points greater change in body fat mass than placebo
See also: Difference between percentages and percentage points
For those who prefer big reviews than single studies, we’ve got you covered:
Does it really reduce inflammation?
Counterintuitive as it may seem, yes. By means of reducing oxidative stress. Given that things that reduce oxidative stress tend to reduce inflammation, and in turn tend to reduce assorted disease risks (from diabetes to cancer to Alzheimer’s), this probably has more knock-on benefits too, but we don’t have room to explore all of those today.
Fresh peppers are best for this, but dried peppers (such as when purchased as a ground spice in the supermarket, or when purchased as a capsule-based supplement) still have a very respectable anti-inflammatory effect:
- Capsaicinoids, Polyphenols and Antioxidant Activities of Capsicum annuum: Comparative Study of the Effect of Ripening Stage and Cooking Methods
- A Review on the Effect of Drying on Antioxidant Potential of Fruits and Vegetables
How much should we take?
It’s recommended to start at a low dose and gradually increase it, but 2–6mg of capsaicin per day is the standard range used in studies.
If you’re getting this from peppers, then for example cayenne pepper (a good source of capsaicin) contains around 2.5mg of capsaicin per 1 gram of cayenne.
In the case of capsules, if for example you don’t like eating hot pepper, this will usually mean taking 2–6 capsules per day, depending on dosage.
Make sure to take it with plenty of water!
Where can we get it?
Fresh peppers or ground spice from your local grocery store is fine. Your local health food store probably sells the supplements, too.
If you’d like to buy it online, here is an example product on Amazon.
Note: options on Amazon were more limited than usual, so this product is not vegan, and probably not halal or kosher, as the capsule contains an unspecified gelatin.

10 Simple Japanese Habits For Healthier & Longer Life
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.
You don’t have to be Japanese or live in Okinawa to enjoy the benefits of healthy longevity. A lot of it comes down to simple habits:
Easy to implement
We’ll not keep the 10 habits a mystery; they are:
- Start the day with hot water: drinking hot water in the morning helps with hydration, warming the body, and aiding digestion.
- Enjoy a hearty breakfast: Japanese breakfasts are traditionally filling, nutritious, and help promote energy and longevity. Typical components include rice, miso soup, fish, and pickles.
- Take balanced meals: Japanese education emphasizes nutrition from a young age, promoting balanced meals with proteins, fiber, and vitamins & minerals.
- Enjoy fermented foods: fermented foods, such as nattō and soy-based condiments, support digestion, heart health, and the immune system.
- Drink green tea and matcha: both are rich in health benefits; preparing matcha mindfully adds a peaceful ritual to daily life too.
- Keep the “80% full” rule: “hara hachi bu” encourages eating until 80% full, which can improve longevity and, of course, prevent overeating.
- Use multiple small dishes: small servings and a variety of dishes help prevent overeating and ensure a diverse intake of nutrients.
- Gratitude before and after meals: saying “itadakimasu” and “gochisousama” promotes mindful eating, and afterwards, good digestion. Speaking Japanese is of course not the key factor here, but rather, do give yourself a moment of reflection before and after meals.
- Use vinegar in cooking: vinegar, often used in sushi rice and sauces like ponzu, adds flavor and offers health benefits, mostly pertaining to blood sugar balance.
- Eat slowly: Eating at a slower pace will improve digestion, and can enhance satiety and prevent accidentally overeating.

So, no question/request too big or small
❝What happens when you age in your sixties?❞
The good news is, a lot of that depends on you!
But, speaking on averages:
While it’s common for people to describe being over 50 as being “over the hill”, halfway to a hundred, and many greetings cards and such reflect this… Biologically speaking, our 60s are more relevant as being halfway to our likely optimal lifespan of 120. Humans love round numbers, but nature doesn’t care for such.
- In our 60s, we’re now usually the “wrong” side of the menopausal metabolic slump (usually starting at 45–55 and taking 5–10 years), or the corresponding “andropause” where testosterone levels drop (usually starting at 45 and a slow decline for 10–15 years).
- In our 60s, women will now be at a higher risk of osteoporosis, due to the above. The risk is not nearly so severe for men.
- In our 60s, if we’re ever going to get cancer, this is the most likely decade for us to find out.
- In our 60s, approximately half of us will suffer some form of hearing loss
- In our 60s, our body has all but stopped making new T-cells, which means our immune defenses drop (this is why many vaccines/boosters are offered to over-60s, but not to younger people)
While at first glance this does not seem a cheery outlook, knowledge is power.
- We can take HRT to avoid the health impact of the menopause/andropause
- We can take extra care to look after our bone health and avoid osteoporosis
- We can make sure we get the appropriate cancer screenings when we should
- We can take hearing tests, and if appropriate find the right hearing aids for us
- We can also learn to lip-read (this writer relies heavily on lip-reading!)
- We can take advantage of those extra vaccinations/boosters
- We can take extra care to boost immune health, too
Your body has no idea how many times you’ve flown around the sun and nor does it care. What actually makes a difference to it, is how it has been treated.

The Easiest Way To Take Up Journaling
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.
Dear Diary…
It’s well-established that journaling is generally good for mental health. It’s not a magical panacea, as evidenced by The Diaries of Franz Kafka for example (that man was not in good mental health). But for most of us, putting our thoughts and feelings down on paper (or the digital equivalent) is a good step for tidying our mind.
And as it can be said: mental health is also just health.
But…
What to write about?
It’s about self-expression (even if only you will read it), and…
❝Writing about traumatic, stressful or emotional events has been found to result in improvements in both physical and psychological health, in non-clinical and clinical populations.
In the expressive writing paradigm, participants are asked to write about such events for 15–20 minutes on 3–5 occasions.
Those who do so generally have significantly better physical and psychological outcomes compared with those who write about neutral topics.❞
Source: Emotional and physical health benefits of expressive writing
In other words, write about whatever moves you.
Working from prompts
If you read the advice above and thought “but I don’t know what moves me”, then fear not. It’s perfectly respectable to work from prompts, such as:
- What last made you cry?
- What last made you laugh?
- What was a recent meaningful moment with family?
- What is a serious mistake that you made and learned from?
- If you could be remembered for just one thing, what would you want it to be?
In fact, sometimes working from prompts has extra benefits, precisely because it challenges us to examine things we might not otherwise think about.
If a prompt asks “What tends to bring you most joy recently?” and the question stumps you, then a) you now are prompted to look at what you can change to find more joy b) you probably wouldn’t have thought of this question—most depressed people don’t, and if you cannot remember recent joy, then well, we’re not here to diagnose, but let’s just say that’s a symptom.
A quick aside: if you or a loved oneare prone to depressive episodes, here’s a good resource, by the way:
The Mental Health First-Aid That You’ll Hopefully Never Need
And in the event of the mental health worst case scenario:
The six prompts we gave earlier are just ideas that came to this writer’s mind, but they’re (ok, some bias here) very good ones. If you’d like more though, here’s a good resource:
550+ Journal Prompts: The Ultimate List
The Good, The Bad, and The Ugly
While it’s not good to get stuck in ruminative negative thought spirals, it is good to have a safe outlet to express one’s negative thoughts/feelings:
Remember, your journal is (or ideally, should be) a place without censure. If you fear social consequences should your journal be read, then using an app with a good security policy and encryption options can be a good idea for journaling
Finch App is a good free option if it’s not too cutesy for your taste, because in terms of security:
- It can’t leak your data because your data never leaves your phone (unless you manually back up your data and then you choose to put it somewhere unsafe)
- It has an option to require passcode/biometrics etc to open the app
As a bonus, it also has very many optional journaling prompts, and also (optional) behavioral activation prompts, amongst more other offerings that we don’t have room to list here.
Take care!

Turns out the viral ‘Sleepy Girl Mocktail’ is backed by science. Should you try it?
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.
Many of us wish we could get a better night’s sleep. Wouldn’t it be great if it was as easy as a mocktail before bed?
That’s what the latest viral trend might have us believe. The “Sleepy Girl Mocktail” is a mix of tart cherry juice, powdered magnesium supplement and soda water. TikTok videos featuring the concoction have garnered hundreds of thousands of views. But, what does the science say? Do these ingredients actually help us sleep?
Tart cherry juice
There is research to show including tart cherry juice in your diet improves overall sleep. Clinical trials show tart cherry juice increases sleep quality and quantity, as well as a lessening insomnia symptoms (compared to a placebo). This could be due to the presence of melatonin, a sleep-promoting hormone, in cherries.
Tart cherry varieties such as Jerte Valley or Montmorency have the highest concentration of melatonin (approximately 0.135 micrograms of melatonin per 100g of cherry juice). Over the counter melatonin supplements can range from 0.5 milligram to over 100 milligrams, with research suggesting those beginning to take melatonin start with a dose of 0.5–2 milligrams to see an improvement in sleep.
Melatonin naturally occurs in our bodies. Our body clock promotes the release of melatonin in the evening to help us sleep, specifically in the two hours before our natural bedtime.
If we want to increase our melatonin intake with external sources, such as cherries, then we should be timing our intake with our natural increase in melatonin. Supplementing melatonin too close to bed will mean we may not get the sleep-promoting benefits in time to get off to sleep easily. Taking melatonin too late may even harm our long-term sleep health by sending the message to our body clock to delay the release of melatonin until later in the evening.
Magnesium – but how much?
Magnesium also works to promote melatonin, and magnesium supplements have been shown to improve sleep outcomes.
However, results vary depending on the amount of magnesium people take. And we don’t yet have the answers on the best dose of magnesium for sleep benefits.
We do know magnesium plays a vital role in energy production and bone development, making it an important daily nutrient for our diets. Foods rich in magnesium include wheat cereal or bread, almonds, cashews, pumpkin seeds, spinach, artichokes, green beans, soy milk and dark chocolate.
Bubbly water
Soda water serves as the base of the drink, rather than a pathway to better sleep. And bubbly water may make the mix more palatable. It is important to keep in mind that drinking fluids close to bedtime can be disruptive to our sleep as it might lead to waking during the night to urinate.
Healthy sleep recommendations include avoiding water intake in the two hours before bed. Having carbonated beverages too close to bed can also trigger digestive symptoms such as bloating, gassiness and reflux during the night.
Bottoms up?
Overall, there is evidence to support trying out the Sleepy Girl Mocktail to see if it improves sleep, however there are some key things to remember:
timing: to get the benefits of this drink, avoid having it too close to bed. Aim to have it two hours before your usual bedtime and avoid fluids after this time
consistency: no drink is going to be an immediate cure for poor sleep. However, this recipe could help promote sleep if used strategically (at the right time) and consistently as part of a balanced diet. It may also introduce a calming evening routine that helps your brain relax and signals it’s time for bed
- maximum magnesium: be mindful of the amount of magnesium you are consuming. While there are many health benefits to magnesium, the recommended daily maximum amounts are 420mg for adult males and 320mg for adult females. Exceeding the maximum can lead to low blood pressure, respiratory distress, stomach problems, muscle weakness and mood problems
sugar: in some of the TikTok recipes sugar (as flavoured sodas, syrups or lollies) is added to the drink. While this may help hide the taste of the tart cherry juice, the consumption of sugar too close to bed may make it more difficult to get to sleep. And sugar in the evening raises blood sugar levels at a time when our body is not primed to be processing sugar. Long term, this can increase our risk of diabetes
sleep environment: follow good sleep hygiene practices including keeping a consistent bedtime and wake time, a wind-down routine before bed, avoiding electronic device use like phones or laptops in bed, and avoiding bright light in the evening. Bright light works to suppress our melatonin levels in the evening and make us more alert.
What about other drinks?
Other common evening beverages include herbal tisanes or teas, hot chocolate, or warm milk.
Milk can be especially beneficial for sleep, as it contains the amino acid tryptophan, which can promote melatonin production. Again, it is important to also consider the timing of these drinks and to avoid any caffeine in tea and too much chocolate too close to bedtime, as this can make us more alert rather than sleepy.
Getting enough sleep is crucial to our health and wellbeing. If you have tried multiple strategies to improve your sleep and things are not getting better, it may be time to seek professional advice, such as from a GP.

Eat Better, Feel Better – by Giada de Laurentis
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 yesterday’s edition of 10almonds, we reviewed Dr. Aujla’s “The Doctor’s Kitchen“; today we’re reviewing a different book about healing through food—in this case, with a special focus on maintaining energy and good health as we get older.
De Laurentis may not be a medical doctor, but she is a TV chef, and not only holds a lot of influence, but also has access to a lot of celebrity doctors and such; that’s reflected a lot in her style and approach here.
The recipes are clear and easy to follow; well-illustrated and nicely laid-out.
This cookbook’s style is less “enjoy this hearty dish of rice and beans with these herbs and spices” and more “you can serve your steak salad with white beans and sweet shallot dressing on a bed of organic quinoa if you haven’t already had your day’s serving of grains, of course”.
It’s a little fancier, in short, and more focused on what to cut out, than what to include. On account of that, this could make it a good contrast to yesterday’s book, which had the opposite focus.
She also recommends assorted adjuvant practices; some that are evidence-based, like intermittent fasting and meditation, and some that are not, like extreme detox-dieting, and acupuncture (which has no bearing on gut health).
Bottom line: if you like the idea of eating for good health, and prefer a touch of celebrity lifestyle to your meals, this one’s a good book for you.
