Hanging Exercises For Complete Beginners & Older Adults
Hanging (not the kind with a gallows) is great for the heath, improving not just strength and mobility, but also—critically—looking after spinal health too.
In this video, Angela Raynor explains how this exercise is accessible to almost anyone (yes, even if you have a very weak grip that cannot support your weight):

Tuesday’s Expert Insights
The Sleep Doctor Is [Not Sleeping] In
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:
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:
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.

Alleviate Chronic Stress With Well-Evidenced Adaptogens
Cortisol is great if you need to suddenly fight a tiger. It’s not so great if you're just dealing with ongoing daily stresses. Chronically high cortisol does physical damage to your body and brain, and it also reduces your body's own ability to heal itself, leading to burnout and fatigue.
That's why it can be good to give your body and brain some help against it, with well-evidenced adaptogens (substances found to aid the body in dealing with stress naturally).
Evinature's "Exhale" is a calming blend of 3 ingredients known for exactly that (all of which we at 10almonds have featured before in our “Research Review Mondays”):
ashwagandha
chamomile
mimosa bark
...to help get your body and brain back into balance.
And as a bonus? A balanced nervous system has been shown to improve overall health, mood, digestion, restorative sleep, and cognitive function.

One-Minute Book Review
Women Living Deliciously – by Florence Given
“Wouldst thou like to live deliciously?” as the line goes, and this book answers that, and how.
While roundly aimed at women, as per the title, this book will be of benefit to anyone who finds that society has wanted to keep you small and contained, and that perhaps you were meant for better.
The book is divided into three sections:
Excavating
Planting
Blooming
…which broadly describes the process the author takes us through, of:
Digging up what is wrong
Putting better things in place
Enjoying life
This is important, because otherwise a lot of people will understandably exhort us to step 3 (enjoying life), without really thinking about steps 1 and 2.
Her wording of it is important too, it wasn’t just being flowery for floweriness’ sake—rather, it highlights the nature of the process: while “enjoy life” seems like a thing-in-itself (as Kant might say), in reality, there’s another necessary thing (or series of things) behind it. In contrast, the gardening metaphor renders it clear: how will your flowers bloom if you do not plant them? And what good will planting them do if the soil is not right for them?
So, she gives us a “ground upwards” therapeutic approach.
The style throughout is casual but sincere and heartfelt, and while this is a book of personal change rather than social change, it does reference feminism throughout so if that’s not for you, then neither is this book.
Bottom line: this is a lot more than just a pep talk or a book of platitudes; it’s a lot of concrete, applicable stuff to markedly live life better.
PS: we notice a one-star review on Amazon expressed disappointment upon discovering that this is not a recipe book. So please be aware, the only recipe in this book is the recipe for a fulfilling and vibrant life 😎
