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…

Do you have children? If yes, how on earth is this doable?

This is another cruel modern irony, we know more about the importance of sleep then ever before, yet we’ve built such a horrible world for sleep.

Light pollution, noise pollution, blue light emitting devices, being “connected” 24x7, synthetic bedding materials, global man made crisis to worry about.

Now study after study on how getting more sleep is important.

Just listen to your body. It knows what you need better than you do. Which is why you don't have to think about beating your heart or processing food in your stomach. Any amount of cognitive increases are most likely related to the fact that your body can relay the excess to other areas such as the brain.

How are you measuring "improved cognition, better health and overall feeling"?

I don't think you need to measure having a better overall feeling. If someone says they feel poorly then they feel poorly. Suppose there was some object way to measure such a thing, what are you going to do with that metric? Imagine being depressed and going to the doctor only for them to say, "no you're not, look at this metric!".

This reply works for a lot of self-improvement advice I read on HN.

In principle this sounds pretty ideal. Sleeping, or resting, when you need and not force an arbitrary societal schedule on yourself. But, I'm guessing that you don't go into an office nor have a lot of meetings? Do you live alone or does it work with a family around the house?

My circumstances vary. If I'm sharing space with someone, I ask that they don't wake me up unless it's urgent, and that they don't talk to or engage me after I wake up, until I signal that I'm ready.

No, I don't go into the office anymore. I live a pauper's existence compared to the past, when I lived like royalty, "earning" enough to pay rent on my own nice apartment in Manhattan, buying new clothes and things regularly, as much as whatever food I wanted, and so on. Though compared to majority of humans and other animals, I'm still doing very well in terms of survival and comfort.

My finances are almost non-existence, and my sense of happiness and self-fulfillment is through the roof.

This is similar to my "drink when you're thirsty" method for remaining hydrated. There's a whole industry built on the premise that we're unable to regulate our own water intake without the help of apps and special water bottles. I've not found that to be the case myself.

No, of course this would be somewhat different with children.

However, this is how I would also raise a child, letting them sleep as much and whenever they want.

When I was a child myself, my parents were in disagreement. My dad's opinion that I should be "broken in" so that I am better able to integrate into society. My mom thought more along the lines of what I describe.

Seeing that my dad had a societal job while my mom raised me, she largely won out.

I think I have her defense and sheltering of me to thank for being blessed with rarely having problems in this department.

Earlier quoted context omitted.

I wake between 11:00 and 13:00 for years now. And I go to sleep between 2:00 and 4:00.

When I stop using alarms and stop forcing myself to go to sleep early, my hours seem to converge to something very similar to yours. I experience the "shifting forward" until I get to 2am-11am, and the shifting stops. I've noticed the same pattern on roommates and family members as well.

It wasn't always like that.

I fondly the time between school and university, when I was unemployed.

I was awake until 7 and slept until 16. I didn't even party much at that time.
