Sleep: yes, you really do still need it!
We asked you how much sleep you usually get, and got the above-pictured, below-described set of responses:
- A little of a third of all respondents selected the option “< 7 hours”
- However, because respondents also selected options such as < 6 hours, < 5 hours, and < 4 hours, so if we include those in the tally, the actual total percentage of respondents who reported getting under 7 hours, is actually more like 62%, or just under two thirds of all respondents.
- Nine respondents, which was about 5% of the total, reported usually getting under 4 hours sleep
- A little over quarter of respondents reported usually getting between 7 and 8 hours sleep
- Fifteen respondents, which was a little under 10% of the total, reported usually getting between 8 and 9 hours of sleep
- Three respondents, which was a little under 2% of the total, reported getting over 9 hours of sleep
- In terms of the classic “you should get 7–9 hours sleep”, approximately a third of respondents reported getting this amount.
You need to get 7–9 hours sleep: True or False?
True! Unless you have a (rare!) mutated ADRB1 gene, which reduces that.
The way to know whether you have this, without genomic testing to know for sure, is: do you regularly get under 6.5 hours sleep, and yet continue to go through life bright-eyed and bushy-tailed? If so, you probably have that gene. If you experience daytime fatigue, brain fog, and restlessness, you probably don’t.
About that mutated ADRB1 gene:
NIH | Gene identified in people who need little sleep
Quality of sleep matters as much as duration, and a lot of studies use the “RU-Sated” framework, which assesses six key dimensions of sleep that have been consistently associated with better health outcomes. These are:
- regularity / usual hours
- satisfaction with sleep
- alertness during waking hours
- timing of sleep
- efficiency of sleep
- duration of sleep
But, that doesn’t mean that you can skimp on the last one if the others are in order. In fact, getting a good 7 hours sleep can reduce your risk of getting a cold by three or four times (compared with six or fewer hours):
Behaviorally Assessed Sleep and Susceptibility to the Common Cold
^This study was about the common cold, but you may be aware there are more serious respiratory viruses freely available, and you don’t want those, either.
Napping is good for the health: True or False?
True or False, depending on how you’re doing it!
If you’re trying to do it to sleep less in total (per polyphasic sleep scheduling), then no, this will not work in any sustainable fashion and will be ruinous to the health. We did a Mythbusting Friday special on specifically this, a while back:
Could Just Two Hours Sleep Per Day Be Enough?
PS: you might remember Betteridge’s Law of Headlines
If you’re doing it as a energy-boosting supplement to a reasonable night’s sleep, napping can indeed be beneficial to the health, and can give benefits such as:
However! There is still a right and a wrong way to go about it, and we wrote about this previously, for a Saturday Life Hacks edition of 10almonds:
How To Nap Like A Pro (No More “Sleep Hangovers”!)
As we get older, we need less sleep: True or False
False, with one small caveat.
The small caveat: children and adolescents need 9–12 hours sleep because, uncredited as it goes, they are doing some seriously impressive bodybuilding, and that is exhausting to the body. So, an adult (with a normal lifestyle, who is not a bodybuilder) will tend to need less sleep than a child/adolescent.
But, the statement “As we get older, we need less sleep” is generally taken to mean “People in the 65+ age bracket need less sleep than younger adults”, and this popular myth is based on anecdotal observational evidence: older people tend to sleep less (as our survey above shows! For any who aren’t aware, our readership is heavily weighted towards the 60+ demographic), and still continue functioning, after all.
Just because we survive something with a degree of resilience doesn’t mean it’s good for us.
In fact, there can be serious health risks from not getting enough sleep in later years, for example:

Finish What You Start – by Peter Hollins
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.
For some people, getting started is the problem. For others of us, getting started is the easy part! We just need a little help not dropping things we started.
There are summaries at the starts and ends of sections, and many “quick tips” to get you back on track.
As a taster: one of these is “temptation bundling“, combining unpleasant things with pleasant. A kind of “spoonful of sugar” approach.
Hollins also discusses hyperbolic discounting (the way we tend to value rewards according to how near they are, and procrastinate accordingly). He offers a tool to overcome this, too, the “10–10–10 rule“.
Also dealt with is “the preparation trap“, and how to know when you have enough information to press on.
For a lot of us, the places we’re most likely to drop a project is 20% in (initial enthusiasm wore off) or 80% in (“it’s nearly done; no need to worry about it”). Those are the times when the advices in this book can be particularly handy!
All in all, a great book for seeing a lot of things to completion.

How to be kind to yourself (without going to a day spa)
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.
“I have to be hard on myself,” Sarah told me in a recent telehealth psychology session. “I would never reach my potential if I was kind and let myself off the hook.”
I could empathise with this fear of self-compassion from clients such as Sarah (not her real name). From a young age, we are taught to be kind to others, but self-kindness is never mentioned.
Instead, we are taught success hinges on self-sacrifice. And we need a healthy inner critic to bully us forward into becoming increasingly better versions of ourselves.
But research shows there doesn’t have to be a trade-off between self-compassion and success.
Self-compassion can help you reach your potential, while supporting you to face the inevitable stumbles and setbacks along the way.
What is self-compassion?
Self-compassion has three key ingredients.
1. Self-kindness
This involves treating yourself with the same kindness you would extend towards a good friend – via your thoughts, feelings and actions – especially during life’s difficult moments.
For instance, if you find yourself fixating on a minor mistake you made at work, self-kindness might involve taking a ten-minute walk to shift focus, and reminding yourself it is OK to make mistakes sometimes, before moving on with your day.
2. Mindfulness
In this context, mindfulness involves being aware of your own experience of stress or suffering, rather than repressing or avoiding your feelings, or over-identifying with them.
Basically, you must see your stress with a clear (mindful) perspective before you can respond with kindness. If we avoid or are consumed by our suffering, we lose perspective.
3. Common humanity
Common humanity involves recognising our own experience of suffering as something that unites us as being human.
For instance, a sleep-deprived parent waking up (for the fourth time) to feed their newborn might choose to think about all the other parents around the world doing exactly the same thing – as opposed to feeling isolated and alone.
It’s not about day spas, or booking a manicure
When Sarah voiced her fear that self-compassion would prevent her success, I explained self-compassion is distinct from self-indulgence.
“So is self-compassion just about booking in more mani/pedis?” Sarah asked.
Not really, I explained. A one-off trip to a day spa is unlikely to transform your mental health.
Instead, self-compassion is a flexible psychological resilience factor that shapes our thoughts, feelings and actions.
It’s associated with a suite of benefits to our wellbeing, relationships and health.
What does the science say?
Over the past 20 years, we’ve learned self-compassionate people enjoy a wide range of benefits. They tend to be happier and have fewer psychological symptoms of distress.
Those high on self-compassion persevere following a failure. They say they are more motivated to overcome a personal weakness than those low on self-compassion, who are more likely to give up.
So rather than feeling trapped by your inadequacies, self-compassion encourages a growth mindset, helping you reach your potential.
However, self-compassion is not a panacea. It will not change your life circumstances or somehow make life “easy”. It is based on the premise that life is hard, and provides practical tools to cope.
It’s a factor in healthy ageing
I research menopause and healthy ageing and am especially interested in the value of self-compassion through menopause and in the second half of life.
Because self-compassion becomes important during life’s challenges, it can help people navigate physical symptoms (for instance, menopausal hot flushes), life transitions such as divorce, and promote healthy ageing.
I’ve also teamed up with researchers at Autism Spectrum Australia to explore self-compassion in autistic adults.
We found autistic adults report significantly lower levels of self-compassion than neurotypical adults. So we developed an online self-compassion training program for this at-risk population.
Three tips for self-compassion
You can learn self-compassion with these three exercises.
1. What would you say to a friend?
Think back to the last time you made a mistake. What did you say to yourself?
If you notice you’re treating yourself more like an enemy than a friend, don’t beat yourself up about it. Instead, try to think about what you might tell a friend, and direct that same friendly language towards yourself.
2. Harness the power of touch
Soothing human touch activates the parasympathetic “relaxation” branch of our nervous system and counteracts the fight or flight response.
Specifically, self-soothing touch (for instance, by placing both hands on your heart, stroking your forearm or giving yourself a hug) reduces cortisol responses to psychosocial stress.
3. What do I need right now?
Sometimes, it can be hard to figure out exactly what self-compassion looks like in a given moment. The question “what do I need right now” helps clarify your true needs.
For example, when I was 37 weeks pregnant, I woke up bolt awake one morning at 3am.
Rather than beating myself up about it, or fretting about not getting enough sleep, I gently placed my hands on my heart and took a few deep breaths. By asking myself “what do I need right now?” it became clear that listening to a gentle podcast/meditation fitted the bill (even though I wanted to addictively scroll my phone).

Canned Tuna vs Canned Sardines – 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 canned tuna to canned sardines, we picked the sardines.
Why?
This comparison is unfair, but practical—because both are sold next to each other in the supermarket and often used for similar things.
It’s unfair because in a can of tuna, there is tuna meat, whereas in a can of sardines, there is sardine meat, skin, and bones.
Consequently, sardines outperform tuna in almost everything, because a lot of nutrients are in the skin and bones.
To be completely unambiguous:
Sardines have more vitamins and minerals by far (special shout-out to calcium, of which sardines contain 6000% more), and more choline (which is sometimes reckoned as a vitamin, sometimes not).
Tuna does have marginally more protein, and less fat. If you are trying to limit your cholesterol intake, then that could be an argument for choosing tuna over sardines.
All in all: the sardines are more nutrient dense by far, are good sources of vitamins and minerals that tuna contains less of (and in many cases only trace amounts of), and for most people this will more than offset the difference in cholesterol, especially if having not more than one can per day.
About that skin and bones…
That’s where the real benefit for your joints lies, by the way!

Are you ready for the least comfortable bed? The reviews are in, and…
Let’s get straight to the point
“Laura Try” tries out health things and reports on her findings. And in this case…
- She noted up front that the claims for this are to improve relaxation, alleviate muscle pain, and improve sleep.
- It also is said to help with myofascial release specifically, which can improve flexibility and mobility (as well as contributing to the alleviation of muscle pain previously mentioned)
- She did not enjoy it at first! Shocking nobody, it was uncomfortable and even somewhat painful. However, after a while, it became less painful and more comfortable—except for trying standing on it, which still hurt (this writer has one too, and I often stand on it at my desk, whenever I feel my feet need a little excitement—it’s probably good for the circulation, but that is just a hypothesis)
- Soon, it became relaxing. Writer’s note: that raised hemicylindrical pillow she’s using? Try putting it under your neck instead, to stimulate the vagus nerve.
- While it is best use on bare skin, the effect can be softened by wearing a thin later of clothing between you and the mat.
- She got hers for £71 GBP (this writer got hers for a fraction of that price from Aldi—and here’s an example product on Amazon, at a more mid-range price)

Successful Aging – by Dr. Daniel Levitin
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 all know about age-related cognitive decline. What if there’s a flipside, though?
Neuroscientist Dr. Daniel Levitin explores the changes that the brain undergoes with age, and notes that it’s not all downhill.
From cumulative improvements in the hippocampi to a dialling-down of the (often overfunctioning) amygdalae, there are benefits too.
The book examines the things that shape our brains from childhood into our eighties and beyond. Many milestones may be behind us, but neuroplasticity means there’s always time for rewiring. Yes, it also covers the “how”.
We learn also about the neurogenesis promoted by such simple acts as taking a different route and/or going somewhere new, and what other things improve the brain’s healthspan.
The writing style is very accessible “pop-science”, and is focused on being of practical use to the reader.
Bottom line: if you want to get the most out of your aging wizening brain, this book is a great how-to manual.

Yoga for Better Sleep – by Mark 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.
The book has, as you might expect:
- postural exercises
- breathing exercises
- meditation exercises
Instructions given in all of the above categories are clear and easy to follow, and there are photographic illustrations too where appropriate.
What sets it apart from many books of this kind is that it also has chapters dedicated to various specific circumstances; the many actual reasons people seriously struggle to sleep; not just “screentime too late”, but for example deprepression, sleep apnea, hyperarousal, or even just aging.
As well as the comprehensive exercises, there are also many tips, tricks, hacks, and workarounds—it’s a practical guidebook with practical advice.
While the book is about yogic practices, the author also does tackle this holistically, acknowledging that there are many factors going on, and that yogic practices should be one more string to our sleep-improving bow—as we continue with other general good advice for good sleep too, have medical tests if it seems appropriate, that kind of thing. Basically, to have one’s assorted approaches work together with synergistic effect.
Bottom line: this book will quite possibly put you to sleep! But only in the best possible way.
