Why You Probably Need More Sleep

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:
- Increased alertness
- Helps with learning
- Improved memory
- Boost to immunity
- Enhance athletic performance
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:
Sleep deficiency promotes Alzheimer’s disease development and progression

What gets measured, gets done. Sleep tracking apps can be a really good tool for getting one’s sleep on a healthier track. We compared and contrasted some popular ones:

Fitness Walking and Bodyweight Exercises – by Frank S. Ring
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.
A lot of exercise manuals assume that the reader has a “basic” body (nothing Olympian, but nothing damaged either). As we get older, increasingly few of us fall into the “but nothing damaged either” category!
Here’s where Ring brings to bear his decades of experience as a coach and educator, and also his personal recovery from a serious back injury.
The book covers direct, actionable exercise advice (with all manner of detail), and also offers mental health tips he’s learned along the way.
Ring, like us, is a big fan of keeping things simple, so he focusses on “the core four” of bodyweight exercises:
- Pushups
- Squats
- Lunges
- Planks
These four exercises get a whole chapter devoted to them, though! Because there are ways to make each exercise easier or harder, or have different benefits. For example, adjustments include:
- Body angle
- Points of contact
- Speed
- Pausing
- Range of motion
This, in effect, makes a few square meters of floor (and perhaps a chair or bench) your fully-equipped gym.
As for walking? Ring enjoys and extols the health benefits, and/but also uses his walks a lot for assorted mental exercises, and recommends we try them too.
A fine book for anyone who wants to gain and/or maintain good health, but doesn’t pressingly want to join a gym or start pumping iron!

NADᐩ Against Aging
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.
Nicotinamide adenine dinucleotide, or “NAD” to its friends, is a coenzyme produced in the human body (amongst other places), and it is critical for cellular energy metabolism, but there’s more to it than that.
Today we’ll be looking mostly at NAD+, of which the + indicates the positive formal charge of one of its nitrogen atoms. We won’t get too much into the chemistry of this, but we will mention that it’s a cofactor with NADH—the former accepting electrons and the latter donating electrons.
Both NAD+ and NADH are critical to good health, but we’re going to focus on NAD+ for the simple reason that it gets depleted with aging.
Note: it gets depleted with aging.
Chronological age is not so important here, but there is a direct relationship between biological aging and NAD+ depletion.
For example, healthy centenarians tend not to have depleted NAD+ levels. Further, its depletion (in those in whom it is depleted) is then a causal factor for many age-related diseases:
❝Remarkably, ageing is accompanied by a gradual decline in tissue and cellular NAD+ levels in multiple model organisms, including rodents and humans.
This decline in NAD+ levels is linked causally to numerous ageing-associated diseases, including cognitive decline, cancer, metabolic disease, sarcopenia and frailty.
Many of these ageing-associated diseases can be slowed down and even reversed by restoring NAD+ levels.❞
~ Dr. Rosalba Perrone et al.
Read in full: NAD+ metabolism and its roles in cellular processes during ageing
As for restoring those NADᐩ levels, that does help in interventional trials, whether by supplementing directly, or with NAD precursors*:
❝NAD+ levels steadily decline with age, resulting in altered metabolism and increased disease susceptibility.
Restoration of NAD+ levels in old or diseased animals can promote health and extend lifespan, prompting a search for safe and efficacious NAD-boosting molecules that hold the promise of increasing the body’s resilience, not just to one disease, but to many, thereby extending healthy human lifespan.❞
~ Dr. David Sinclair et al.
Read more: Therapeutic Potential of NAD-Boosting Molecules: The In Vivo Evidence
*There are actually also other NAD-boosting molecules besides NAD itself and its precursors. For example, the liver will not produce NADᐩ unless it has aminocarboxymuconate-semialdehyde decarboxylase (or “ACMSD”, to its friends), which limits the production of NADᐩ. Why, you ask? The theory is that it is a kind of evolutionary conservativism, much like not lighting a fire without the ability to put it out. In any case, taking ACMSD-blockers will thus result in an increased endogenous production of NADᐩ.
You can read about this here:
De novo NAD+ synthesis enhances mitochondrial function and improves health
Nor is taking supplements or drugs the only way to get more of it; there’s an enzyme nicotinamide phosphoribosyltransferase (“NAMPT”, to its friends) involved in the synthesis of NADᐩ, and exercise boosts levels by 127% (i.e., it more than doubles the levels), based on a modest three-week exercise bike regimen:
Skeletal muscle NAMPT is induced by exercise in humans
And to underline that point, another study found that resistance training (so, a different kind of exercise from that of the previous study) boosts levels of NADᐩ itself by the same 127%:
One way to get more out of NADᐩ
We’ll get straight to the point: it works very well paired with a senolytic agent, i.e. something that kills aging cells so that they get recycled sooner:
NAD+, Senolytics, or Pyruvate for Healthy Aging?

What Happens To Your Body When You Do 100 Glute Bridges Every Day
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.
Not just for a sculpted butt:
Benefits
With consistent daily glute bridge practice, you may expect:
- Rounder, toned butt: targets the gluteus maximus, toning and lifting the butt for a rounder appearance.
- Improved posture: strengthens glutes to support the spine and pelvis, alleviating lower back and hip pain. Stretches tight hip flexors from prolonged sitting.
- Stronger lower back: glutes support the lower back and spine, reducing pain and making it easier to lift heavy objects. Activating the glutes transfers force from legs to core, preventing injuries.
- Stronger knees: stabilizes the knee joint and promotes alignment by engaging glutes, hamstrings, and quadriceps, reducing knee pain.
- Sculpted hamstrings: contracts hamstrings during lifts for strength, while stretching them on the way down increases flexibility.
- Increased hip flexibility: strengthens muscles around the hip joint, improving mobility and counteracting tight hips from sedentary habits.
- Reduced back pain: strengthens glutes to correct pelvic tilt and reduce strain on the lower back.
- Faster running speed: improves hip extension, strengthens hamstrings, and activates the gluteus medius for better running power and balance.
- Enhanced strength training performance: strengthens glutes, back, and knees, improving performance in exercises like squats and deadlifts.
As for how to get going, the video offers the following very sound advice: begin with 25–30 reps per session and gradually increase to sets of 100 daily. It should take about 5 minutes (that’s 3 seconds per repetition). Results can be seen in as little as 2 weeks, with significant changes after a month of consistent practice.

Ras El-Hanout
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.
This is a spice blend, and its name (رأس الحانوت) means “head of the shop”. It’s popular throughout Morocco, Algeria, and Tunisia, but can often be found elsewhere. The exact blend will vary a little from place to place and even from maker to maker, but the general idea is the same. The one we provide here today is very representative (and for an example of its use, see our Marrakesh Sorghum Salad recipe!).
Note: we’re giving all the quantities in whole tsp today, to make multiplying/dividing easier if you want to make more/less ras el-hanout.
You will need
- 6 tsp ground ginger
- 6 tsp ground coriander seeds
- 4 tsp ground turmeric
- 4 tsp ground sweet cinnamon
- 4 tsp ground cumin
- 2 tsp ground allspice ← not a spice mix! This is the name of a spice!
- 2 tsp ground cardamom
- 2 tsp ground anise
- 2 tsp ground black pepper
- 1 tsp ground cayenne pepper
- 1 tsp ground cloves
Note: you may notice that garlic and salt are conspicuous by their absence. The reason for this is that they are usually added separately per dish, if desired.
Method
1) Mix them thoroughly
That’s it! Enjoy!

You Are the One You’ve Been Waiting For – by Dr. Richard Schwartz
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.
As self-therapy approaches go, the title here could be read two ways: as pop-psychology fluff, or a suggestion of something deeper. And, while written in a way to make it accessible to all, we’re happy to report the content consists of serious therapeutic ideas, presented clearly.
Internal Family Systems (IFS) is a large, internationally recognized, and popular therapeutic approach. It’s also an approach that lends itself quite well to self-therapy, as this book illustrates.
Dr. Schwartz kicks off by explaining not IFS, but the problem that it solves… We (most of us, anyway) have over the course of our lives tried to plug the gaps in our own unmet psychological needs. And, that can cause resentment, strain, and can even be taken out on others if we’re not careful.
The real meat of the book, however, is in its illustrative explanations of how IFS works, and can be applied by an individual. The goal is to recognize all the parts that make us who we are, understand what they need in order to be at peace, and give them that. Spoiler: most what they will need is just being adequately heard, rather than locked in a box untended.
One of the benefits of using this book for self-therapy, of course, is that it requires a lot less vulnerability with a third party.
But, speaking of which, what of these intimate relationships the subtitle of the book referenced? Mostly the benefits to such come from a “put your own oxygen mask on first” angle… but the book does also cover discussions between intimate partners, and approaches to love, including what the author calls “courageous love”.
Bottom line: this is a great book if you want to do some “spring-cleaning of the soul” and live a little more lightly as a result.

The End of Alzheimer’s – by Dr. Dale Bredesen
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.
This one didn’t use the “The New Science Of…” subtitle that many books do, and this one actually is a “new science of”!
Which is exciting, and/but comes with the caveat that the overall protocol itself is still undergoing testing, but the results so far are promising. The constituent parts of the protocol are for the most already well-established, but have not previously been put together in this way.
Dr. Bredesen argues that Alzheimer’s Disease is not one condition but three (medical consensus agrees at least that it is a collection of conditions, but different schools of thought slice them differently), and outlines 36 metabolic factors that are implicated, and the good news is, most of them are within our control.
Since there’s a lot to put together, he also offers many workarounds and “crutches”, making for very practical advice.
The style of the book is on the hard end of pop-science, that is to say while the feel and tone is very pop-sciencey, there are nevertheless a lot of words that you might know but your spellchecker probably wouldn’t. He does explain everything along the way, but this does mean that if you’re not already well-versed, you can’t just dip in to a later point without reading the earlier parts.
Bottom line: even if you only implement half the advice in this book, you’ll be doing your long-term cognitive health a huge favor.
