5 Sleep Phenotypes, By Actual Science
You probably know people can be broadly divided into “early birds” and “night owls”:
Early Bird Or Night Owl? Genes vs Environment
…and then the term “hummingbird” gets used for a person who flits between the two.
That’s three animals so far. If you read a book we reviewed recently, specifically this one:
The Power of When – by Dr. Michael Breus
…then you may have used the guide within to self-diagnose your circadian rhythm type (chronotype) according to Dr. Breus’s system, which divides people into bears, lions, wolves, and dolphins.
That’s another four animals. If you have a FitBit, it can “diagnose” you with being those and/or a menagerie of others, such as giraffe, hedgehog, parrot, and tortoise:
How Fitbit Developed the Sleep Profile Experience (Part 2 – Sleep Animals)
Five million nights
A team of researchers recently took a step away from this veritable zoo of 11 different animals and counting, and used a sophisticated modelling system to create a spatial-temporal map of people’s sleep habits, and this map created five main “islands” that people’s sleep habits could settle on, or sometimes move from island to island.
Those “five million nights” by the way? It was actually 5,095,798 nights! You might notice that would take from the 2020s to the 15970s to complete, so this was rather a matter of monitoring 33,152 individuals between January and October of the same year. Between them, they got those 5,095,798 nights of sleep (or in some cases, nights of little or no sleep, but still, they were there for the nights).
The five main phenotypes that the researchers found were:
- What we think of as “normal” sleep. In this phenotype, people get about eight hours of uninterrupted sleep for at least six days in a row.
- As above for half the nights, but they only sleep for short periods of time in bouts of less than three hours the other half.
- As per normal sleep, but with one interrupted night per week, consisting of a 5 hour sleep period and then broken sleep for a few more hours.
- As per normal sleep generally, but with occasional nights in which long bouts of sleep are separated by a mid-sleep waking.
- Sleeping for very short periods of time every night. This phenotype was the rarest the researchers found, and represents extremely disrupted sleep.
As you might suspect, phenotype 1 is healthier than phenotype 5. But that’s not hugely informational, as the correlation between getting good sleep and having good health is well-established. So, what did the study teach us?
❝We found that little changes in sleep quality helped us identify health risks. Those little changes wouldn’t show up on an average night, or on a questionnaire, so it really shows how wearables help us detect risks that would otherwise be missed.❞
More specifically,
❝We found that the little differences in how sleep disruptions occur can tell us a lot. Even if these instances are rare, their frequency is also telling. So it’s not just whether you sleep well or not – it’s the patterns of sleep over time where the key info hides❞
…and, which gets to the absolute point,
❝If you imagine there’s a landscape of sleep types, then it’s less about where you tend to live on that landscape, and more about how often you leave that area❞
In other words: if your sleep pattern is not ideal, that’s one thing and it’d probably be good to address it, by improving your sleep. However, if your sleep pattern changes phenotype without an obvious known reason why, this may be considered an alarm bell warning of something else that needs addressing, which may be an underlying illness or condition—meaning it can be worthwhile being a little extra vigilant when it comes to regular health screenings, in case something new has appeared.

The Well Plated Cookbook – by Erin Clarke
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.
Clarke’s focus here is on what she calls “stealthy healthy”, with the idea of dishes that feel indulgent while being great for the health.
The recipes, of which there are well over 100, are indeed delicious and easy to make without being oversimplified, and since she encourages the use of in-season ingredients, many recipes come with a “market swaps” substitution guide, to make each recipe seasonal.
The book is largely not vegetarian, let alone vegan, but the required substitutions will be second-nature to any seasoned vegetarian or vegan. Indeed, “skip the meat sometimes” is one of the advices she offers near the beginning of the book, in the category of tips to make things even healthier.
Bottom line: if you want to add dishes to your repertoire that are great for entertaining and still super-healthy, this book will be a fine addition to your collection.

Your Health Audit, From Head To Toe
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.
Health Audit Time
Here at 10almonds, we often cover quite specific things, ranging from “the effect of sodium on organs other than your heart” to “make this one small change to save your knees while driving”.
But, we’re each a whole person, and we need to take care of the whole organism that makes up the wonderful being that we each are. If we let one part of it drop in health too much, the others will soon follow suit because of the knock-on effects.
So, let’s do a quick self-check-up, and see what can be done for each! How’s your…
Mental Health
We’re doing this audit head-to-to, so let’s start it here, because mental health is also just health, and it’s difficult to tackle the others without having this one at least under control!
Are you experiencing chronic stress? Anxiety? Depression? Joy?
If you answered “no” to “joy” but also “no” to “depression”, you might want to rethink your answer to “depression”, by the way. Life should be a joyous thing!
Some resources to address your mental health:
Brain Health
Your brain is a big, powerful organ. It uses more of your daily energy (in the physiological sense of the word, we’re talking calories and mitochondria and ATP) than any other organ, by far.
And when it comes to organ failure, if your brain fails, then having the best joints in the world won’t help you, for example.
Some resources to address your brain health:
- Brain Food? The Eyes Have It
- How To Reduce Your Alzheimer’s Risk
- The 6 Dimensions Of Sleep (And Why They Matter)
Heart Health
Everything depends on your heart, head to toe. Tirelessly pumping blood with oxygen, nutrients, and agents of your immune system all around your body, all day every day for your entire life.
What’s your resting heart rate like? How about your blood pressure? And while we’re on the topic of blood… how’s your blood sugar health?
These are all important things to a) know about and b) keep on top of!
Some resources to address your heart health:
- 1-Minute Heart Health Check-Up Tips
- A Five-Point Plan For Heart Health
- High Blood Pressure? Try These!
Gut Health
By cell count, we’re about 10% human and 90% bacteria. By gene count, also. Pretty important, therefore, that we look after our trillions of tiny friends that keep our organism working.
Most people in N. America, for example, get vastly under the recommended daily amount of fiber, and that’s just the most basic courtesy we could do for these bugs that keep us alive (they need that fiber to live, and their process of consuming it is beneficial to us in a stack of ways).
Some resources to address your gut health:
- Making Friends With Your Gut (You Can Thank Us Later)
- The Surprising Link Between Gut Health And Serotonin
- The Vagus Nerve: The Brain-Gut Highway!
Hormonal Health
Hormones are weird and wonderful and affect so much more than the obvious sex-related functions (but yes, those too). A lot of people don’t realize it, but having our hormones in good order or not can make the difference between abject misery and a happy, fulfilling life.
Some resources to address your hormonal health:
- What Does “Balance Your Hormones” Even Mean?
- Healthy Hormones And How To Hack Them
- Too Much Or Too Little Testosterone?
Bone/Joint Health
Fear nothing! For you are a ghost operating a skeleton clad in flesh. But also, you know, look after that skeleton; you only get one! Being animals, we’re all about movement, and being humans, we’ve ended up with some lifestyle situations that aren’t great for that mobility. We sit too much; we walk too little; we cramp ourselves into weird positions (driving, anyone?), and we forget the range of motion we’re supposed to have. But let’s remember…
Some resources to address your bone/joint health:
- Collagen’s benefits are more than skin deep
- Cool As A Cucumber (Move Over, Glucosamine + Chondroitin)
- 5 Best Bodyweight Exercises For Incredible Mobility
Lastly…
While it’s good to do a little self-audit like this every now and again, it’s even better to get a professional check-up!
As engineers say: if you don’t schedule time for maintenance, your equipment will schedule it for you.

The Most Anti Aging Exercise
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 referenced this (excellent) video before, but never actually put it under the spotlight in one of these features, so here we go!
Deep squats
It’s about deep squats, also called Slav squats, Asian squats, sitting squats, resting squats, or various other names. However, fear not; you don’t need to be Slavic or Asian to do it; you just need to practice.
As for why this is called “anti-aging”, by the way, it’s because being able to get up off the ground is one of the main tests of age-related mobility decline, and if you can deep-squat comfortably, then you can do that easily. And so long as you continue being able to deep-squat comfortably, you’ll continue to be able to get up off the ground easily too, because you have the strength in the right muscles, as well as the suppleness, comfort with range of motion, and balance (those stabilizing muscles are used constantly in a deep squat, whereas Western lifestyle sitting leaves those muscles very neglected and thus atrophied).
Epidemiological note: chairs, couches, and assorted modern conveniences reduce the need for squatting in daily life, leading to stiffness in joints, muscles, tendons, and ligaments. Many adults in developed countries struggle with deep squats due to lack of use, not aging. Which is a problem, because a lack of full range of motion in joints causes wear and tear, leading to chronic pain and degenerative joint diseases. People in countries where squatting is a common resting position have lower incidences of osteoarthritis, for example—contrary to what some might expect, squatting does not harm joints but rather protects them from arthritis and knee pain. Strengthening leg muscles through squatting can alleviate knee pain, whereas knee pain is often worsened by inactivity.
Notwithstanding the thumbnail, which is showing an interim position, one’s feet should be flat on the ground, by the way, and one’s butt should be nearby, just a few inches off the ground (in other words, the position that we see her in for most of this video).
Troubleshooting: if you’re accustomed to sitting in chairs a lot, then this may be uncomfortable at first. Zuzka advises us to go gently, and/but gradually increase our range of motion and (equally importantly) duration in the resting position.
You can use a wall or doorway to partially support you, at first, if you struggle with mobility or balance. Just try to gradually use it less, until you’re comfortable deep-squatting with no support.
Since this is not an intrinsically very exciting exercise, once you build up the duration for which you’re comfortable deep-squatting, it can be good to get in the habit of “sitting” this way (i.e. deep squatting, still butt-off-the-floor, but doing the job of sitting) while doing other things such as working (if you have an appropriate work set-up for that*), reading, or watching TV.
*this is probably easiest with a laptop placed on an object/surface of appropriate height, such as a coffee table or such. As a bonus, having your hands in front of you while working will also bring your center of gravity forwards a bit, making the position easier and more comfortable to maintain. This writer (hi, it’s me) prefers her standing desk for work in general, with a nice ergonomic keyboard and all that, but if using a laptop from time to time, then squatting is a very good option.
In terms of working up duration, if you can only manage seconds to start with, that’s fine. Just do a few more seconds each time, until it’s 30, 60, 120, and so on until it’s 5 minutes, 10, 15, and so on.
You can even start that habit-forming while you’re still in the “seconds at a time” stage! You can deep-squat just for some seconds while you:
- pick up something from the floor
- check on something in the oven
- get something out of the bottom of the fridge
…etc!
For more on all this, plus many visual demonstrations including interim exercises to get you there if it’s difficult for you at first, enjoy:

Exercise, therapy and diet can all improve life during cancer treatment and boost survival. Here’s how
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.
With so many high-profile people diagnosed with cancer we are confronted with the stark reality the disease can strike any of us at any time. There are also reports certain cancers are increasing among younger people in their 30s and 40s.
On the positive side, medical treatments for cancer are advancing very rapidly. Survival rates are improving greatly and some cancers are now being managed more as long-term chronic diseases rather than illnesses that will rapidly claim a patient’s life.
The mainstays of cancer treatment remain surgery, chemotherapy, radiation therapy, immunotherapy, targeted therapy and hormone therapy. But there are other treatments and strategies – “adjunct” or supportive cancer care – that can have a powerful impact on a patient’s quality of life, survival and experience during cancer treatment.
PeopleImages.com – Yuri A/Shutterstock Keep moving if you can
Physical exercise is now recognised as a medicine. It can be tailored to the patient and their health issues to stimulate the body and build an internal environment where cancer is less likely to flourish. It does this in a number of ways.
Exercise provides a strong stimulus to our immune system, increasing the number of cancer-fighting immune cells in our blood circulation and infusing these into the tumour tissue to identify and kill cancer cells.
Our skeletal muscles (those attached to bone for movement) release signalling molecules called myokines. The larger the muscle mass, the more myokines are released – even when a person is at rest. However, during and immediately after bouts of exercise, a further surge of myokines is secreted into the bloodstream. Myokines attach to immune cells, stimulating them to be better “hunter-killers”. Myokines also signal directly to cancer cells slowing their growth and causing cell death.
Exercise can also greatly reduce the side effects of cancer treatment such as fatigue, muscle and bone loss, and fat gain. And it reduces the risk of developing other chronic diseases such as heart disease and type 2 diabetes. Exercise can maintain or improve quality of life and mental health for patients with cancer.
Emerging research evidence indicates exercise might increase the effectiveness of mainstream treatments such as chemotherapy and radiation therapy. Exercise is certainly essential for preparing the patient for any surgery to increase cardio-respiratory fitness, reduce systemic inflammation, and increase muscle mass, strength and physical function, and then rehabilitating them after surgery.
These mechanisms explain why cancer patients who are physically active have much better survival outcomes with the relative risk of death from cancer reduced by as much as 40–50%.
Mental health helps
The second “tool” which has a major role in cancer management is psycho-oncology. It involves the psychological, social, behavioural and emotional aspects of cancer for not only the patient but also their carers and family. The aim is to maintain or improve quality of life and mental health aspects such as emotional distress, anxiety, depression, sexual health, coping strategies, personal identity and relationships.
Supporting quality of life and happiness is important on their own, but these barometers can also impact a patient’s physical health, response to exercise medicine, resilience to disease and to treatments.
If a patient is highly distressed or anxious, their body can enter a flight or fight response. This creates an internal environment that is actually supportive of cancer progression through hormonal and inflammatory mechanisms. So it’s essential their mental health is supported.
Chemotherapy can be stressful on the body and emotional reserves. Shutterstock Putting the good things in: diet
A third therapy in the supportive cancer care toolbox is diet. A healthy diet can support the body to fight cancer and help it tolerate and recover from medical or surgical treatments.
Inflammation provides a more fertile environment for cancer cells. If a patient is overweight with excessive fat tissue then a diet to reduce fat which is also anti-inflammatory can be very helpful. This generally means avoiding processed foods and eating predominantly fresh food, locally sourced and mostly plant based.
Some cancer treatments cause muscle loss. Avoiding processed foods may help. Shutterstock Muscle loss is a side effect of all cancer treatments. Resistance training exercise can help but people may need protein supplements or diet changes to make sure they get enough protein to build muscle. Older age and cancer treatments may reduce both the intake of protein and compromise absorption so supplementation may be indicated.
Depending on the cancer and treatment, some patients may require highly specialised diet therapy. Some cancers such as pancreatic, stomach, esophageal, and lung cancer can cause rapid and uncontrolled drops in body weight. This is called cachexia and needs careful management.
Other cancers and treatments such as hormone therapy can cause rapid weight gain. This also needs careful monitoring and guidance so that, when a patient is clear of cancer, they are not left with higher risks of other health problems such as cardiovascular disease and metabolic syndrome (a cluster of conditions that boost your risk of heart disease, stroke and type 2 diabetes).
Working as a team
These are three of the most powerful tools in the supportive care toolbox for people with cancer. None of them are “cures” for cancer, alone or together. But they can work in tandem with medical treatments to greatly improve outcomes for patients.
If you or someone you care about has cancer, national and state cancer councils and cancer-specific organisations can provide support.
For exercise medicine support it is best to consult with an accredited exercise physiologist, for diet therapy an accredited practising dietitian and mental health support with a registered psychologist. Some of these services are supported through Medicare on referral from a general practitioner.
For free and confidential cancer support call the Cancer Council on 13 11 20.

The Paleo Diet
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.
What’s The Real Deal With The Paleo Diet?
The Paleo diet is popular, and has some compelling arguments for it.
Detractors, meanwhile, have derided Paleo’s inclusion of modern innovations, and have also claimed it’s bad for the heart.
But where does the science stand?
First: what is it?
The Paleo diet looks to recreate the diet of the Paleolithic era—in terms of nutrients, anyway. So for example, you’re perfectly welcome to use modern cooking techniques and enjoy foods that aren’t from your immediate locale. Just, not foods that weren’t a thing yet. To give a general idea:
Paleo includes:
- Meat and animal fats
- Eggs
- Fruits and vegetables
- Nuts and seeds
- Herbs and spices
Paleo excludes:
- Processed foods
- Dairy products
- Refined sugar
- Grains of any kind
- Legumes, including any beans or peas
Enjoyers of the Mediterranean Diet or the DASH heart-healthy diet, or those with a keen interest in nutritional science in general, may notice they went off a bit with those last couple of items at the end there, by excluding things that scientific consensus holds should be making up a substantial portion of our daily diet.
But let’s break it down…
First thing: is it accurate?
Well, aside from the modern cooking techniques, the global market of goods, and the fact it does include food that didn’t exist yet (most fruits and vegetables in their modern form are the result of agricultural engineering a mere few thousand years ago, especially in the Americas)…
…no, no it isn’t. Best current scientific consensus is that in the Paleolithic we ate mostly plants, with about 3% of our diet coming from animal-based foods. Much like most modern apes.
Ok, so it’s not historically accurate. No biggie, we’re pragmatists. Is it healthy, though?
Well, health involves a lot of factors, so that depends on what you have in mind. But for example, it can be good for weight loss, almost certainly because of cutting out refined sugar and, by virtue of cutting out all grains, that means having cut out refined flour products, too:
Diet Review: Paleo Diet for Weight Loss
Measured head-to-head with the Mediterranean diet for all-cause mortality and specific mortality, it performed better than the control (Standard American Diet, or “SAD”), probably for the same reasons we just mentioned. However, it was outperformed by the Mediterranean Diet:
So in lay terms: the Paleo is definitely better than just eating lots of refined foods and sugar and stuff, but it’s still not as good as the Mediterranean Diet.
What about some of the health risk claims? Are they true or false?
A common knee-jerk criticism of the paleo-diet is that it’s heart-unhealthy. So much red meat, saturated fat, and no grains and legumes.
The science agrees.
For example, a recent study on long-term adherence to the Paleo diet concluded:
❝Results indicate long-term adherence is associated with different gut microbiota and increased serum trimethylamine-N-oxide (TMAO), a gut-derived metabolite associated with cardiovascular disease. A variety of fiber components, including whole grain sources may be required to maintain gut and cardiovascular health.❞
Bottom line:
The Paleo Diet is an interesting concept, and certainly can be good for short-term weight loss. In the long-term, however (and: especially for our heart health) we need less meat and more grains and legumes.

6 Signs Of A Heart Attack… A Month In Advance
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 people know the signs of a heart attack when it’s happening, but how about before it’s too late to avoid it?
The signs
- Unusual fatigue: persistent tiredness that doesn’t improve with rest
- Shortness of breath: unexplained breathlessness during light activities or rest, which can be caused by fluid buildup in the lungs (because the heart isn’t circulating blood as well as it should)
- Chest discomfort: pain, pressure, tightness, or aching in the chest due to reduced blood flow to the heart muscle—often occurring during physical exertion or emotional stress
- Frequent indigestion: means that heartburn could be heart-related! This is about persistently reoccurring discomfort or pain in the upper abdomen
- Sleep disturbances: difficulties falling asleep, staying asleep, or waking up abruptly
- Excessive sweating: unexplained cold sweats or sudden sweating without physical exertion or excessive heat, can be a response to the decreased oxygen levels caused by less efficient blood flow
Note: this is a list of warning signs, not a diagnostic tool. Any or even all of these could be caused by something else. Just, don’t ignore the signs and do get yourself checked out.
