I'd like to share my sleeping practice which I've developed after several years of focusing on it and trying to recreate the pre-industrial (and possibly pre-farming) sleep patterns my ancestors had for millions of years before the last few thousand. Whenever I feel tired, I lay down to rest. Whenever I am sleeping, I allow myself to sleep until I am "fully slept", meaning I can lay there for a while, still physicall…

What are your other practices, I love this pre-industrial modality

I've written a few comments in this tree, please let me know if you'd like to know anything else I haven't mentioned.

you do not sound like you have kids. if you do, how do you possibly achieve this with kids.

I think with kids it's not possible, have to make some sacrifices. I think it's important to have multiple full-time caretakers.

thanks for sharing, had a quick couple of follow up questions, how do you unsubscribe from paying monthly rent ? also did you get married and have kids ? if yes how did they factor in to your life ?

I have not dared have children until I'm certain I can take care of them, and I think I'm getting close. I don't believe in marriage, but I'm in a relationship. My partners accept me and support me. I am low-maintenance, so it is not a burden on them. My rider is clean water, unprocessed food, Web hosting, a 104-key, a computer, and an Internet connection. I unsubscribed from rent by not renewing my lease and moving…

thanks for sharing again. Living minimalistically and not marrying all the comforts of life is the key I guess. Makes sense although you will have to return to paying rent and a fixed place you call your own when you have kids. Goodluck.

I have a completely different problem - I almost never dream. If I do, they're very short, and very difficult to remember.

Thats me too, I almost never dream , although I am sure I do dream every night, just that when I wake up I have no recollection, perhaps if it was an intense dream then I may sense if it was a sad dream or a happy dream, but rarely do I remember anything specific. I've always wondered if this is normal.

I wonder too. Most people I know, who I've told this to, think its very odd that I never dream.

Probably related, I've struggled with depression nearly my entire adult life. I've learned to cope, drug free, but yea, I'm sure on a neural level my brain just isn't firing at peak levels like a normal person.

Main thing for me has been quitting caffeine after lunchtime. For most of my life I just drank caffeine as if it were synomynous with hydration - coffee in the morning, diet sodas in the afternoon, teas in the evenings. And for years, I wondered why I couldn't sleep... Withdrawal was surprising. On the first day, I fell asleep at 6pm until the next morning. The next day, 8pm until morning. Felt ill for a week. Ached…

I recently went on a break from caffeine, and while the withdrawals weren't bad (I was only ever a one coffee in the morning person), I have since noticed how INCREDIBLY sensitive I am to caffeine. Now that I have no tolerance, having one coffee at any point during the day will completely ruin my sleep for that night (from ~7h down to ~4h with lots of awake time). I'm at a point now where I don't think coffee is for…

I’m the same way, also very sensitive.

I never thought a morning coffee can affect sleep. But once I quit, I realized just how much it does.

Now I use coffee if I wanna stay up late on a Friday night - a cappuccino in the morning makes sure I’m wide awake until midnight.

Love it! You are light-years ahead of me. I recently came up with analogy of pet sleep, like you said, cats and dogs just sleep here and there if the feel like it. I tried to implement that on my weekends but wasn't very successful so far.

How do you keep your sleep rhythms while you're working?

How do you know whether those teachers were actually wise or just repeating bullshit that sounded good?

Because I witnessed their abilities.

Which abilities were those, and how do you know whether their abilities were caused by or in spite of their hydration habits?

I work whenever not sleeping or otherwise occupied.

I've set a goal for myself of one commit daily, and I usually overshoot.

Is this study saying that more than 8 hours of sleep correlates with negative effects on cognition?

I'm a bit confused by this statement as well : "For cognition only, associations shift to a negative association of sleep duration and cognition for participants sleeping more than 8 hr a day."

I used to think that our body know better. But I realise it doesn't do what is better but rather what it is used to do. I felt I had to eat sweets frequently, drink coca-coca everyday and 3 meals a day etc. My body felt terrible when I didn't. I stopped listed to what my body wanted and consciously stop those things. First week it was really painful. Second week I got used to. Third week I completely changed. Now I h…
