Calculate (And Enjoy) The Perfect Night’s Sleep

This is Dr. Michael Breus, a clinical psychologist and sleep specialist, and he wants you to get a good night’s sleep, every night.
First, let’s assume you know a lot of good advice about how to do that already in terms of environment and preparation, etc. If you want a recap before proceeding, then we recommend:
Get Better Sleep: Beyond The Basics
Now, what does he want to add?
Wake up refreshed
Of course, how obtainable this is will depend on the previous night’s sleep, but there is something important we can do here regardless, and it’s: beat sleep inertia.
Sleep inertia is what happens when we wake up groggy (for reasons other than being ill, drugged, etc) rather than refreshed. It’s not actually related to how much sleep we have, though!
Rather, it pertains to whether we woke up during a sleep cycle, or between cycles:
- If we wake up between sleep cycles, we’ll avoid sleep inertia.
- If we wake up during a sleep cycle, we’ll be groggy.
Deep sleep generally occurs in 90-minute blocks, albeit secretly that is generally 3× 20 minute blocks in a trenchcoat, with transition periods between, during which the brainwaves change frequency.
REM sleep generally occurs in 20 minute blocks, and will usually arrive in series towards the end of our natural sleep period, to fit neatly into the last 90-minute cycle.
Sometimes these will appear a little out of order, because we are complicated organic beings, but those are the general trends.
In any case, the take-away here is: interrupt them at your peril. You need to wake up between cycles. There are two ways you can do this:
- Carefully calculate everything, and set a very precise alarm clock (this will work so long as you are correct in guessing how long it will take you to fall asleep)
- Use a “sunrise” lamp alarm clock, that in the hour approaching your set alarm time, will gradually increase the light. Because the body will not naturally wake up during a cycle unless a threat is perceived (loud noise, physical rousing, etc), the sunrise lamp method means that you will wake up between sleep cycles at some point during that hour (towards the beginning or end, depending on what your sleep balance/debt is like).
Do not sleep in (even if you have a sleep debt); it will throw everything out.
Caffeine will not help much in the morning
Assuming you got a reasonable night’s sleep, your brain has been cleansed of adenosine (a sleepy chemical), and if you are suffering from sleep inertia, the grogginess is due to melatonin (a different sleepy chemical).
Caffeine is an adenosine receptor blocker, so that will do nothing to mitigate the effects of melatonin in your brain that doesn’t have any meaningful quantity of adenosine in it in the morning.
Adenosine gradually accumulates in the brain over the course of the day (and then gets washed out while we sleep), so if you’re sleepy in the afternoon (for reasons other than: you just had a nap and now have sleep inertia again), then caffeine can block that adenosine in the afternoon.
Of course, caffeine is also a stimulant (it increases adrenaline levels and promotes vasoconstriction), but its effects at healthily small doses are modest for most people, and you’d do better by splashing cold water on your face and/or listening to some upbeat music.

Time your naps correctly (if you take naps)
Dr. Breus has a lot to say about this, based on a lot of clinical research, but as it’s entirely consistent with what we’ve written before (based on the exact same research), to save space we’ll link to that here:
How To Be An Expert Nap-Artist (With No “Sleep-Hangovers”)
Calculate your bedtime correctly
Remember what we said about sleep cycles? This means that that famous “7–9 hours sleep” is actually “either 7½ or 9 hours sleep”—because those are multiples of 90 minutes, whereas 8 hours (for example) is not.
So, consider the time you want to get up (ideally, this should be relatively early, and the same time every day), and then count backwards either 7½ or 9 hours sleep (you choose), add 20–30 minutes to fall asleep, and that’s your bedtime.
So for example: if you want to have 7½ hours sleep and get up at 6am, then your bedtime is anywhere between 10pm and 10:10pm.
Remember how we said not to sleep in, even if you have a sleep debt? Now is the time to pay it off, if you have one. If you normally sleep 7½ hours, then make tonight a 9-hour sleep (plus 20–30 minutes to fall asleep). This means you’ll still get up at 6am, but your bedtime is now anywhere between 8:30pm and 8:40pm.

Parsnips vs Potatoes – 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 parsnips to potatoes, we picked the parsnips.
Why?
To be more specific, we’re looking at russet potatoes, and in both cases we’re looking at cooked without fat or salt, skin on. In other words, the basic nutritional values of these plants in edible form, without adding anything. With this in mind, once we get to the root of things, there’s a clear winner:
Looking at the macros first, potatoes have more carbs while parsnips have more fiber. Potatoes do have more protein too, but given the small numbers involved when it comes to protein we don’t think this is enough of a plus to outweigh the extra fiber in the parsnips.
In the category of vitamins, again a champion emerges: parsnips have more of vitamins B1, B2, B5, B9, C, E, and K, while potatoes have more of vitamins B3, B6, and choline. So, a 7:3 win for parsnips.
When it comes to minerals, parsnips have more calcium copper, manganese, selenium, and zinc, while potatoes have more iron and potassium. Potatoes do also have more sodium, but for most people most of the time, this is not a plus, healthwise. Disregarding the sodium, this category sees a 5:2 win for parsnips.
In short: as with most starchy vegetables, enjoy both in moderation if you feel so inclined, but if you’re picking one, then parsnips are the nutritionally best choice here.

The Book Of Hormones – by Dr. Shweta Patel
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 subtitle promising “through every stage of life” is a slight overstatement, as the book barely touches on puberty, but we know that the vast majority of our readers have left that one far behind in the past, so probably this is not such an issue.
Where the book gives more attention is in general adult life, through the years of potential fertility, into menopause and beyond. This means lots about the hormonal fluctuations inherent to the menstrual cycle (both the normal, and the still-quite-commonly abnormal, e.g. in cases of PCOS etc), the before-during-after of pregnancy, and many hormonal matters that are not related to sex hormones, such as stress-related hormones and food-related hormones. As such, the book certainly lives up to its title; it is indeed “the book of hormones”.
The style is light and conversational; we get a lot of lessons in chemistry here, but it never feels like it, and there’s certainly no hard science, just clear and easy explanations.
Bottom line: if you’d like to understand hormones quite comprehensively but in a light-hearted manner, this book is a very pleasant and educational read.

❓ Q&A With 10almonds Subscribers!
Q: What kind of salt is best for neti pots?
A: Non-iodised salt is usually recommended, but really, any human-safe salt is fine. By this we mean for example:
- Sodium chloride (like most kitchen salts),
- Potassium chloride (as found in “reduced sodium” kitchen salts), or
- Magnesium sulfate (also known as epsom salts).

One Critical Mistake That Costs Seniors Their Mobility

Will Harlow, the over-50s specialist physio, advises what to do instead:
Nose over toes
Often considered the most important test of mobility in later life (or in general, but later life is when it tends to decline) is the ability to get up off the floor without using your arms.
Many seniors, meanwhile, struggle to get out of a chair without using their arms.
Now, sitting in chairs in the first place is not good for the health, but that’s another matter and beyond the scope of today’s article.
If, perchance, you struggle to get up from a chair (especially if it’s low/deep, like many armchairs are) without using your hands, then here’s the way to do it:
- While practicing, cross your arms in front of you, so that you cannot use them.
- Shuffle yourself towards the front of the chair. No, don’t use your arms for this either, do a little butt-walk instead, to get you to the front edge of the chair.
- Lean forwards to position your nose over your toes (hence the mnemonic: “nose over toes”; memorize that!), as this will put your center of gravity where it needs to be.
- Now, push with your feet to rise up and forwards; slowly is better than quickly (quickly may be easier, but slowly will improve your strength and balance).

Yoga Therapy for Arthritis – by Dr. Steffany Moonaz & Erin Byron
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.
Two quick notes to start with:
- One of the problems with arthritis and exercise is that arthritis can often impede exercise.
- Another of the problems with arthritis and exercise is that some kinds of exercise can exacerbate arthritis.
This book deals with both of those issues, by providing yoga specifically tailored to living with arthritis. Indeed, the first-listed author’s PhD in public health was the result of 8 years of study developing an evidence-based yoga program for people with arthritis, including osteoarthritis and rheumatoid arthritis.
The authors take the view that arthritis is a whole-person disease (i.e. it affects all parts of you), and so addressing it requires a whole-person approach, which is what this book delivers.
As such, this is not just a book of asana (yoga postures). It does provide that, of course (as well as breathing exercises), but also its 328 pages additionally cover a lot of conscious work from the inside out, including attention to the brain, energy levels, pain, and so forth, and that the practice of yoga should not merely directly improve the joints via gentle physical exercise, but also should help to heal the whole person, including reducing stress levels, reducing physical tension, and with those two things, reducing inflammation also—and also, due to both that and the asana side of practice, better-functioning organs, which is always a bonus.
The style is interesting, as it refers to both science (8 pages of hard-science bibliography) and yogic principles (enough esoterica to put off, say, James Randi or Penn & Teller). This reviewer is very comfortable with both, and so if you, dear reader, are comfortable with both too, then you will surely enjoy this book.
Bottom line: if you or a loved one has arthritis, you’ll wish you got this book sooner.

Kiwi Fruit vs Pineapple – 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 kiwi fruit to pineapple, we picked the kiwi.
Why?
In terms of macros, they’re mostly quite comparable, being fruits made of mostly water, and a similar carb count (slightly different proportions of sugar types, but nothing that throws out the end result, and the GI is low for both). Technically kiwi has twice the protein, but they are fruits and “twice the protein” means “0.5g difference per 100g”. Aside from that, and more meaningfully, kiwi also has twice the fiber.
When it comes to vitamins, kiwi has more of vitamins A, B9, C, E, K, and choline, while pineapple has more of vitamins B1, B2, B3, B5, and B6. This would be a marginal (6:5) win for kiwi, but kiwi’s margins of difference are greater per vitamin, including 72x more vitamin E (with a cupful giving 29% of the RDA, vs a cupful of pineapple giving 0.4% of the RDA) and 57x more vitamin K (with a cupful giving a day’s RDA, vs a cupful of pineapple giving a little under 2% of the RDA). So, this is a fair win for kiwi.
In the category of minerals, things are clear: kiwi has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while pineapple has more manganese. An overwhelming win for kiwi.
Looking at their respective anti-inflammatory powers, pineapple has its special bromelain enzymes, which is a point in its favour, but when it comes to actual polyphenols, the two fruits are quite balanced, with kiwi’s flavonoids vs pineapple’s lignans.
Adding up the sections, it’s a clear win for kiwi—but pineapple is a very respectable fruit too (especially because of its bromelain content), so do enjoy both!
