I think a lot of this research seems in the end to lead towards not overthinking these things. Just closely listen to your body. We have wonderful sensors and other mechanisms which is we don't use we will end up losing them. Sleep when you feel sleepy. Wake when you feel awake. Eat when you feel hungry. Drink when you feel thirsty. Really pay attention to what you're body sensors are pointing.

I had a phase of about 1 year where I slept when I was tired, and woke up when I was awake.
I noticed that my total wake+sleep time was 27h (about 8h sleep, and 19h wake). Which resulted in me moving around the clock in about 2week interval. (because of the shift of 27/24)
Be aware, this is pure behavior on instinct, whenever I was tired, I went to sleep, whenever I was awake I got up. I felt great, never tired or groggy.

Of course you notice, that the issue arises pretty quickly with society. Society is not built on a variable schedule.
But it was an eye opening information. I have never read or heard any studies to this phenomenon.
Anyway, looking back this was the only time in my life were I had a fantastic sleep.

After struggling with sleep for almost 10 years, I found that these things work for me:
1. Cold bedroom - below 18C.
2. Having a shower before bed.
3. No caffeine after 12:00.
4. Ear-plugs.
5. Exercising regularly.
6. No bright lights up to 2 hrs before bed.
7. Using my head throughout the day.
8. Refreshing walk an hour or two before bed.

Sometimes, if I get restless legs, 2-400mg of ibuprofen works well. Try not to use it too often though. Also, if I can't fall asleep, listening to something in bed besides silence helps. ASMR-videos are really great.

I'm increasingly more impressed with the progression and quality of your content over the years! Thanks for such incredible content and please keep it up!

I can’t sleep less than 8 hours. It’s physically impossible for me in the long run. After 5 or 6 days or so, I fall asleep while sitting up. 8 to 9 hours seems to be the natural time my body does it without an alarm clock. I’ve always been a “sleeper”, even as a baby.

Personally? Whenever I found myself not watching YouTube or playing video games before bed, (usually due to going somewhere and forgetting to bring my charger, ) my sleep quality skyrockets. It's incredible how much earlier I go to bed, and just how much more high-quality that sleep becomes. Even if it's in a brand-new, hot, and (relatively) uncomfortable room.

Love your content, it’s always so well researched. Thank you

This is crazy because I’ve recently discovered I love to be asleep by 10 and wake up at 5:30 or 6. I always feels amazing through the day and ready to go to bed right around 10

[johnrecker]

I do 7:30 hours of sleep every single day, going to sleep the same time and waking up at 4:30 - changed my life and helped with sleep issues, I’m pretty much invincible now.

This video cannot come at a more fantastic time than this. I have been tracking my sleep for a week now, and I know so much about myself.

[MultiMobCast]

I find watching TV has the least negative impact on my productivity when done in the late evening. However, this has always been a dilemma for me due to the affects on sleep. Glad you helped clear up this conflict

[dinglesworld]

I’ve recently begun to sleep 8-9 hrs and I’ve felt better than ever. Feeling rested, energized!

[masterdevil]

Seeing the progress of your channel and seeing the progress of my own personal journey is it extremely refreshing and I hope and pray for the success of you personally and the success of your channel.

[BrandonGallemore]

Love the new videos man. I've been a fan for a long time and am glad to see the step-up in production. Hope you keep it going for a long time.

My hours are usually 6 to 7hrs of sleep a night. It just depends on if I was tired or not. When I sleep 8hrs I feel groggy and sleepy all day.

[AntonioSanchez-gkel]

Your channel is gold, it blows my mind that this is for free. How it is edited, the amount of research mentioned... real quality, congrats!

[DN-cfrz]

The production quality on your videos is superb, especially the more recent ones. The subtle comedy really helps me enjoy them. Not only am I learning, but I'm able to quietly chuckle while doing so.

[KeshaLukin]

I love how you added some cuts from podcasts and keynotes where "productive" people share their sleeping secrets. Looks like this video is a next level. Also "Let's see Paul Allen's sleep" oh man... Literally me (yes) and my friends looking at sleep app each morning.

[TheFearmoths]

The more I hear about the importance of sleep the harder I find it is to sleep. The irony is that all this talk about sleep is adding to our stress and giving us more reason to lie awake.

One thing I really appreciate about your videos are the small reference bits/entertaining side videos (I don't know what to call them). They really keep me engaged in the video visually and help me process the information.
