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.

Don't forget about the 40-hour work week as part of the "horrible world for sleep".

The thirst mechanism becomes less reliable with age, so older people may find those products beneficial. But yes, for most healthy young to middle aged people, "drink when you're thirsty" is generally fine. Maybe with the added subpoint that if your urine is often colored, try to drink a little more.

Yes, it is important to pay attention to urine, and poop too.

This will sound wierd, but I knew a rancher who could diagnose a calf (correctly, confirmed by a vet) based on those two things. Ironically, he had been developing diabetes, which had he been paying as close attention to waste products he might have caught sooner.

PSA: Look before you flush, it's actually not a bad way to gauge general health.

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…

> A couple of times I think I was coming down with something, I slept for more than 24 hours with only pee breaks. And I woke up feeling fresh as a cucumber, as they say. I don't really take sleeping that seriously in general, but I used to get sick pretty frequently (sick enough to not work, a couple times a year). Nowadays I have a routine, and it's not so different: if I feel a tiny bit sick, I go home, lie in bed…

Agreed; I've worked hard to prioritize sleep in my life, though not to the extent that the parent poster has. But simply stopping, right now, and going to sleep for as long as you need, at the first sign of illness, will save you days of misery.

Every single time I've said "well, I'll just go into the office and if I don't feel well, I can just head home midday", I've regretted it. It's too late.

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…

Our body evolved for an environment without those things that you listed. I think you were right to consciously remove those things from its access. Sleep was always an essential part of the equation, however. Try to imagine how you lived 10K years ago.

Yes, sleep was always essential, but we didn’t have artificial lights and didn’t spend most of our days sitting on our asses. Both are things that probably disturb our natural sleep clues.

Sure... But I'm not giving those up for now. Not sleeping enough for optimal function, I'm not as attached to.

Maybe a little weird, but certainly not surprising to me.

It's the closest you can get non-invasively to looking inside yourself.

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.

IIRC, if you're thirsty, your body has already been dehydrated. Ideally, you'd want to drink before you're thirsty.

I have a very weird problem/issue, maybe someone can help. In my school days I used to maintain a dream diary, where I would note down every dream I had after waking up. I stopped doing that when I got into college, but dreams never stopped and I never stopped analysing and trying to remember the dreams. Fast forward to present time (10 years from school), whenever I want to wake up i.e. after 6-7 hours of sleep I ca…

You need more sleep. That's it. That's the story. There's nothing wrong with you. Trying to set additional alarms, or worrying about how you used to record your dreams... Not relevant. Your body isn't done resting. Stop interrupting it before its done, and you'll find that 8ish hours of uninterrupted sleep is more restful than the quasi-sleep you're getting now.

>Stop interrupting it before its done, and you'll find that 8ish hours of uninterrupted sleep is more restful than the quasi-sleep you're getting now.

Probably true, but I value my free time and I want as much of it as possible. That means staying up late. Spending that time sleeping makes me feel like I live to work, and not work to live.

Yeah, the body has a mechanism to tell us when it needs water. You don't pee when you don't feel the urge to, so I don't drink water when I don't feel the urge to in most cases. I drink some when I first wake up just so I don't forget to drink some, and if I'm exercising I drink a lot

If that is a bulletproof way to handle water intake, why would you worry about "forgetting"?

I know that my sleep quality would increase if 1) I could keep my window open and get fresh air 2) have a silent environment like I did when I was a child/teen living in a remote area. Now I live next to a relatively busy street, so keeping my window open is not possible due to pollution, and using earplugs won't fully solve the noise issue either.
