Exactly, my kids are in elementary school and I’ve been talking with superintendents and high school principals. It’s straightforward to teach kids about the brain as a muscle and sleep as critical to rest and recovery to best power cognition. The glymphatic system gives a clear mechanism and yet I haven’t found many places where it’s being taught as a core part of how to best use your brain. Sleep is still considered a nice to have for brain performance, not a driver of working smarter.

After learning this and reading about lion’s mane reversing plaque induced dementia in rats I started taking it as “brain washing detergent” before bed. It gives me some wildly vivid dreams and I always wake up more refreshed.

How much?

I scoop about 2-3 grams

I don’t feel physically tired in the mornings. I ran in high school 8-10 miles a day and would collapse, waking up dream free. Now I wake up refreshed but I’m sick of watching the same rehashed combinations of dreams. I can do lucid dreaming, but I’d just rather not dream at all

You always dream. That's the thing. Unless something is seriously wrong you dream every night. You might not want to remember them but you'll dream all the same.

Might be a symptom of my good memory? Shame. I like the memory but not the dreams

I think the point would be if you could replace ~8 hours of sleep with ~1-2 hours of meditation. I very much doubt it's a like-for-like replacement, but it might go some way to reducing the need for full sleep, e.g. 2 hours meditating + 2 hours sleeping = 8 hours sleeping.

Is the idea that yoga/meditation are more efficient than sleep at redistributing the cerebral fluid? That would be very surprising.

What people really require for sleep vary a lot. But there are claims some people practicing very intensely, need only 4-6 hours of sleep at night. That's rarely a goal in itself though, as it's not a means to become more efficient or "save time", in a traditional, linear way of thinking at least.

However, the goal of meditation can be very diverse, since there are many different techniques, each with their own aims and side-effects. Generally, the main goal is often to calm the mind, make the body relax and let go of stress. There are many more benefits though, which you only realize when doing personal and experiencial practice over longer periods of time. It's not like the effects are the same for each person even, so it's more like a discovery process rather than do A, B, C techniques for X, Y, Z gains. However, there's a baseline of methods and general health, which is what it's usually used for. Very few people are suited to be munks or living in secluded communes like that. But it can be Very nice to be on a 1-2 week retreat now and then.

If you have any doubts about sleep quantity and quality, worth reading about the glymphatic nervous system, which is so newly discovered likely you didn’t learn about it in school. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4636982/ In short it explains, mechanistically, why poor sleep affects daily cognition, mental health, and age-related declines. Robust scientific theories explain more of the evidence. The glym…

It makes me sad as my SO struggles a lot with sleep. It's been years since she's had a good nights sleep.

Sadly her issues are mostly psychologically rooted due to past trauma, while all the treatments seem to be geared towards "simple" physical issues. She's tried contacting various sleep clinics here and they've all said they can't help.

She struggles a lot with falling asleep, she's exceptionally sensitive to sound and vibration while trying to sleep or sleeping, and if she falls asleep she almost always have nightmares, which significantly reduces the quality of the sleep even if they don't always wake her up.

One issue is that when you're that close to the limit of what is no longer bearable, it's hard to just try things. For example, I've been thinking exposure therapy might help for her sound and light sensitivity, but she's not convinced it'll help and doesn't want to try potentially sleeping even worse for many weeks. Which I understand, but...

Sounds so hard.

I’ve experienced that a moderate or intense exercise regimen can help a lot with sleep.

If she hasn’t tried therapies directed at trauma and recovery that may also be helpful.

Has she tried cannabis? It prevents dream memory formation and can help with nightmares

That's been in use for thousands of years already: yoga, pranayama and meditation. There are courses one can take where one learns this, like Art of Living and any other that follows the same traditions. Yes, there's research on that, and new studies should absolutely gain from this study. Not entirely sure you'll observe the same effect, that depends on meditator, but you can fall asleep during practice. I have over…

It's hilarious to me that these practices are laughed off, trivialized through memes and hyper-objectivity (science can't evaluate their value in a practical manner -> "Lulz hippie-dippie nonsense for ditzy/ungrounded women!!!!" -- Western dolt). Its insane considering their benefits...that are of course tragically perfect for those who would never participate Of course that's a huge generality, I'd say it may be 1 o…

It's dismissed like any other woo woo bullshit: strong claims, no evidence.

Where's the evidence that yoga and meditation accomplish the effects of sleep and how strong is it?
