Could Just Two Hours Sleep Per Day Be Enough?

Polyphasic Sleep… Super-Schedule Or An Idea Best Put To Rest?
What is it?
Let’s start by defining some terms:
- Monophasic sleep—sleeping in one “chunk” per day. For example, a good night’s “normal” sleep.
- Biphasic sleep—sleeping in two “chunks” per day. Typically, a shorter night’s sleep, with a nap usually around the middle of the day / early afternoon.
- Polyphasic sleep—sleeping in two or more “chunks per day”. Some people do this in order to have more hours awake per day, to do things. The idea is that sleeping this way is more efficient, and one can get enough rest in less time. The most popular schedules used are:
- The Überman schedule—six evenly-spaced 20-minute naps, one every four hours, throughout the 24-hour day. The name is a semi-anglicized version of the German word Übermensch, “Superman”.
- The Everyman schedule—a less extreme schedule, that has a three-hours “long sleep” during the night, and three evenly-spaced 20-minute naps during the day, for a total of 4 hours sleep.
There are other schedules, but we’ll focus on the most popular ones here.

Some people have pointed to evidence that suggests humans are naturally polyphasic sleepers, and that it is only modern lifestyles that have forced us to be (mostly) monophasic.
There is at least some evidence to suggest that when environmental light/dark conditions are changed (because of extreme seasonal variation at the poles, or, as in this case, because of artificial changes as part of a sleep science experiment), we adjust our sleeping patterns accordingly.
The counterpoint, of course, is that perhaps when at the mercy of long days/nights at the poles, or no air-conditioning to deal with the heat of the day in the tropics, that perhaps we were forced to be polyphasic, and now, with modern technology and greater control, we are free to be monophasic.
Either way, there are plenty of people who take up the practice of polyphasic sleep.
Ok, But… Why?
The main motivation for trying polyphasic sleep is simply to have more hours in the day! It’s exciting, the prospect of having 22 hours per day to be so productive and still have time over for leisure.
A secondary motivation for trying polyphasic sleep is that when the brain is sleep-deprived, it will prioritize REM sleep. Here’s where the Überman schedule becomes perhaps most interesting:
The six evenly-spaced naps of the Überman schedule are each 20 minutes long. This corresponds to the approximate length of a normal REM cycle.
Consequently, when your head hits the pillow, you’ll immediately begin dreaming, and at the end of your dream, the alarm will go off.
Waking up at the end of a dream, when one hasn’t yet entered a non-REM phase of sleep, will make you more likely to remember it. Similarly, going straight into REM sleep will make you more likely to be aware of it, thus, lucid dreaming.
Read: Sleep fragmentation and lucid dreaming (actually a very interesting and informative lucid dreaming study even if you don’t want to take up polyphasic sleep)
Six 20-minute lucid-dreaming sessions per day?! While awake for the other 22 hours?! That’s… 24 hours per day of wakefulness to use as you please! What sorcery is this?
Hence, it has quite an understandable appeal.
Next Question: Does it work?
Can we get by without the other (non-REM) kinds of sleep?
According to Überman cycle enthusiasts: Yes! The body and brain will adapt.
According to sleep scientists: No! The non-REM slow-wave phases of sleep are essential
Read: Adverse impact of polyphasic sleep patterns in humans—Report of the National Sleep Foundation sleep timing and variability consensus panel
(if you want to know just how bad it is… the top-listed “similar article” is entitled “Suicidal Ideation”)
But what about, for example, the Everman schedule? Three hours at night is enough for some non-REM sleep, right?
It is, and so it’s not as quickly deleterious to the health as the Überman schedule. But, unless you are blessed with rare genes that allow you to operate comfortably on 4 hours per day (you’ll know already if that describes you, without having to run any experiment), it’s still bad.
Adults typically need 7–9 hours of sleep per night, and if you don’t get it, you’ll accumulate a sleep debt. And, importantly:
When you accumulate sleep debt, you are borrowing time at a very high rate of interest!
And, at risk of laboring the metaphor, but this is important too:
Not only will you have to pay it back soon (with interest), you will be hounded by the debt collection agents—decreased cognitive ability and decreased physical ability—until you pay up.
In summary:
- Polyphasic sleep is really very tempting
- It will give you more hours per day (for a while)
- It will give the promised lucid dreaming benefits (which is great until you start micronapping between naps, this is effectively a mini psychotic break from reality lasting split seconds each—can be deadly if behind the wheel of a car, for instance!)
- It is unequivocally bad for the health and we do not recommend it
Bottom line:
Some of the claimed benefits are real, but are incredibly short-term, unsustainable, and come at a cost that’s far too high. We get why it’s tempting, but ultimately, it’s self-sabotage.
(Sadly! We really wanted it to work, too…)

PTSD, But, Well…. Complex.
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.
PTSD is typically associated with military veterans, for example, or sexual assault survivors. There was a clear, indisputable, Bad Thing™ that was experienced, and it left a psychological scar. When something happens to remind us of that—say, there are fireworks, or somebody touches us a certain way—it’ll trigger an immediate strong response of some kind.
These days the word “triggered” has been popularly misappropriated to mean any adverse emotional reaction, often to something trivial.
But, not all trauma is so clear. If PTSD refers to the result of that one time you were smashed with a sledgehammer, C-PTSD (Complex PTSD) refers to the result of having been hit with a rolled-up newspaper every few days for fifteen years, say.
This might have been…
- childhood emotional neglect
- a parent with a hair-trigger temper
- bullying at school
- extended financial hardship as a young adult
- “just” being told or shown all too often that your best was never good enough
- the persistent threat (real or imagined) of doom of some kind
- the often-reinforced idea that you might lose everything at any moment
If you’re reading this list and thinking “that’s just life though”, you might be in the estimated 1 in 5 people with (often undiagnosed) C-PTSD.
How About You? Take The (5mins) Test Here
Now, we at 10almonds are not doctors or therapists and even if we were, we certainly wouldn’t try to diagnose from afar. But, even if there’s only a partial match, sometimes the same advice can help.
So what are the symptoms of C-PTSD?
- A feeling that nothing is safe; we might suddenly lose what we have gained
- The body keeps the score… And it shows. We may have trouble relaxing, an aversion to exercise for reasons that don’t really add up, or an aversion to being touched.
- Trouble sleeping, born of nagging sense that to sleep is to be vulnerable to attack, and/or lazy, and/or negligent of our duties
- Poor self-image, about our body and/or about ourself as a person.
- We’re often drawn to highly unavailable people—or we are the highly unavailable person to which our complementary C-PTSD sufferers are attracted.
- We are prone to feelings of rage. Whether we keep a calm lid on it or lose our temper, we know it’s there. We’re angry at the world and at ourselves.
- We are not quick to trust—we may go through the motions of showing trust, but we’re already half-expecting that trust to have been misplaced.
- “Hell is other people” has become such a rule of life that we may tend to cloister ourselves away from company.
- We may try to order our environment around us as a matter of safety, and be easily perturbed by sudden changes being imposed on us, even if ostensibly quite minor or harmless.
- In a bid to try to find safety, we may throw ourselves into work—whatever that is for us. It could be literally our job, or passion projects, or our family, or community, and in and of itself that’s great! But the motivation is more of an attempt to distract ourselves from The Horrors™.
“Alright, I scored more of those than I care to admit. What now?”
A lot of the answer lies in first acknowledging to yourself what happened, to make you feel the way you do now. If you, for example, have an abject hatred of Christmas, what were your childhood Christmases like? If you fear losing money that you’ve accumulated, what underpins that fear? It could be something that directly happened to you, but it also could just be repeated messages you received from your parents, for example.
It could even be that you had superficially an idyllic perfect childhood. Health, wealth, security, a loving family… and simply a chemical imbalance in your brain made it a special kind of Hell for you that nobody understood, and perhaps you didn’t either.
Unfortunately, a difficult task now lies ahead: giving love, understanding, compassion, and reassurance to the person for whom you may have the most contempt in the world: yourself.
If you’d like some help with that, here are some resources:
ComplexTrauma.org (a lot of very good free resources, with no need for interaction)
CPTSD Foundation (mostly paid courses and the like)
Some final words about healing…
- You are in fact amazing,
- You can do it, and
- You deserve it.

What Your Doctor May Not Tell You About Fibromyalgia – by Dr. R. Paul St Amand
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 core claim of the book is that guaifenesin, an over-the-counter expectorant (with a good safety profile) usually taken to treat a chesty cough, is absorbed from the gastrointestinal tract, and is rapidly metabolized and excreted into the urine—and on the way, it lowers uric acid levels, which is a big deal for fibromyalgia sufferers.
He goes on to explain how the guaifenesin, by a similar biochemical mechanism, additionally facilitates the removal of other excess secretions that are associated with fibromyalgia.
The science for all this is… Compelling and logical, while not being nearly so well-established yet as his confidence would have us believe.
In other words, he could be completely wrong, because adequate testing has not yet been done. However, he also could be right; scientific knowledge is, by the very reality of scientific method, always a step behind hypothesis and theory (in that order).
Meanwhile, there are certainly many glowing testimonials from fibromyalgia sufferers, saying that this helped a lot.
Bottom line: if you have fibromyalgia and do not mind trying a relatively clinically untested (yet logical and anecdotally successful) protocol to lessen then symptoms (allegedly, to zero), then this book will guide you through that and tell you everything to watch out for.

10 Healthiest Foods You Should Eat In The Morning
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 many of us, our creative minds aren’t their absolute best first thing in the morning, and it’s easy to reach for what’s available, if we haven’t planned ahead.
So here’s some inspiration for the coming week! If you’re a regular coffee-and-toast person, at least consider alternating some of these with that:
- Oatmeal with fresh fruit: fiber, energy, protein, vitamins and minerals (10almonds tip: we recommend making it as overnight oats! Same nutrients, lower glycemic index)
- Greek yogurt parfait: probiotic gut benefits, along with all the goodness of fruit
- Avocado toast: so many nutrients; most famous for the healthy fats, but there’s lots more in there too!
- Egg + vegetable scramble: protein, healthy fats, vitamins and minerals, fiber
- Smoothie bowl: many nutrients—But be aware that blending will reduce fiber and make the sugar quicker to enter your bloodstream. Still not bad as an occasional feature for the sake of variety, though!
- Wholegrain pancakes: energy, fiber, and whatever your toppings! Fresh fruit is a top-tier choice; the video suggests maple syrup; we however invite you to try aged balsamic vinegar instead (sounds unlikely, we know, but try it and you’ll see; it is so delicious and your blood sugars will thank you too!)
- Chia pudding: so many nutrients in this one; chia seeds are incredible!
- Quinoa breakfast bowl: the healthy grains are a great start to the day, and contain a fair bit of protein too, and served with nuts, seeds, and diced fruit, many more nutrients get added to the mix. Unclear why the video-makers want to put honey or maple syrup on everything.
- Berries: lots of vitamins, fiber, hydration, and very many polyphenols
For a quick visual overview, and a quick-start preparation guide for the ones that aren’t just “berries” or similar, enjoy this short (3:11) video:

PS: They said 10, and we only counted 9. Where is the tenth one? Who would say “10 things” and then ostensibly only have 9? Who would do such a thing?!
About that chia pudding…
It’s a great way to get a healthy dose of protein, healthy fats, antioxidants, and a lot of other benefits for the heart and brain:

Can I Eat That? – by Jenefer Roberts
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 answer to the question in the title is: you can eat pretty much anything, if you’re prepared for the consequences!
This book looks to give you the information to make your own decisions in that regard. There’s a large section on the science of glucose metabolism in the context of food (other aspects of glucose metabolism aren’t covered), so you will not simply be told “raw carrots are good; mashed potatoes are bad”, you’ll understand many factors that affect it, e.g:
- Macronutrient profiles of food and resultant base glycemic indices
- How the glycemic index changes if you cut something, crush it, mash it, juice it, etc
- How the glycemic index changes if you chill something, heat it, fry it, boil it, etc
- The many “this food works differently in the presence of this other food” factors
- How your relative level of insulin resistance affects things itself
…and much more.
The style is simple and explanatory, without deep science, but with good science and comprehensive advice.
There are also the promised recipes; they’re in an appendix at the back and aren’t the main meat of the book, though.
Bottom line: if you’ve ever found it confusing working out what works how in the mysterious world of diabetes nutrition, this book is a top tier demystifier.

Heal & Reenergize Your Brain With Optimized Sleep Cycles
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.
Sometimes 8 hours sleep can result in grogginess while 6 hours can result in waking up fresh as a daisy, so what gives? Dr. Tracey Marks explains, in this short video.
Getting more than Zs in
Sleep involves 90-minute cycles, usually in 4 stages:
- Stage 1: (drowsy state): brief muscle jerks; lasts a few minutes.
- Stage 2: (light sleep): sleep spindles for memory consolidation; 50% of total sleep.
- Stage 3 (deep sleep): tissue repair, immune support, brain toxin removal via the glymphatic system.
- Stage 4 (REM sleep): emotional processing, creativity, problem-solving, and dreaming.
Some things can disrupt some or all of those. To give a few common examples:
- Alcohol: impairs REM sleep.
- Caffeine: hinders deep sleep even if consumed hours before bed.
- Screentime: delays sleep onset due to blue light (but not by much); the greater problem is that it can also disrupt REM sleep due to mental stimulation.
To optimize things, Dr. Marks recommends:
- 90-minute rule: plan sleep to align with full cycles (e.g: 22:30 to 06:00 = 7½ hours, which is 5x 90-minute cycles).
- Smart alarms: use sleep-tracking apps with built-in alarm, to wake you up during light sleep phases.
- Strategic naps: keep naps to 20 minutes or a full 90-minute cycle.
- Pink noise: improves deep sleep.
- Meal timing: avoid eating within 3 hours of bedtime.
- Natural light: get morning light exposure in the morning to strengthen circadian rhythm.

The Pains That Good Posture Now Can Help You Avoid Later
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. Murat Dalkilinç explains:
As a rule…
Posture is the foundation for all body movements and good posture helps the body adapt to stress.
Problems arise when poor posture causes muscles to overwork in ways that are not good for them, becoming tight or inhibited over time. Bad posture can lead to wear and tear on joints, increase accident risk, and make some organs (like the lungs, which feed everything else with the oxygen necessary for normal functioning) less efficient. It’s also of course linked to issues like scoliosis, tension headaches, and back pain, and can even affect emotions and pain sensitivity.
Good posture includes straight alignment of vertebrae when viewed from the front/back, and three natural curves in a (very!) gentle S-shape when viewed from the side. Proper posture allows for efficient movement, reduces fatigue, and minimizes muscle strain. For sitting posture, the neck should be vertical, shoulders relaxed, arms close to the body, and knees at a right angle with feet flat.
But really, one should avoid sitting, to whatever extent is reasonably possible. Standing is better than sitting; walking is better than standing. Movement is crucial, as being stationary for extended periods, even with good posture, is not good for our body.
Advices given include: adjust your environment, use ergonomic aids, wear supportive shoes, and keep moving. Regular movement and exercise keep muscles strong to support the body.
