It used to be 9-10 hrs in my twenties. With young kids it was much less but has now steadied at about 7-8 hrs. It’s usually interrupted through the night. I can fall back asleep at the drop of a hat.

My wife finds getting to sleep incredibly hard, she can be awake for hours reading, trying to fall asleep, so for her some nights would minus 2-3 hrs from that.

She is always brighter and more energetic than me, I never seem to get enough sleep.

Not everyone is the same but what worked well to fix my now rare sleeping issues is to keep it consistent. I go to bed about the same time and I wake up about the same time. Also during weekends and holidays. I also used to keep about the same time despite the stupid summer and winter time zone changes, but I don’t anymore and I am more tired for a few days twice a year.

I also sleep better when I’m physically active. And sex helps to fall asleep.

I am getting 4 hours of sleep a night and then 4 hours of napping time during the day. That’s not a good approach but I’m working FT during the day to fund my startup venture. My job requires me to wake up at 2:30am and be at work for 4:15am. I’m usually done by 12:45ish and I then need to nap because of the lack of sleep . So it depends really but I would love to have 8 hours in a go.

4-6 hours. Always struggled with sleep. I wish I could slow time down for others and have like 60 hours a day to do stuff. Just ain’t enough time with so much to do. I also don’t feel comfortable taking sleeping pills, and I have struggled with insomnia since I was a kid.

I do try to get some movement in during the day. I try going to bed around “normal” times but end up waking around 2-4am.

On the bright side maybe I’ll just live a fulfilling life and my body will eventually just sudo shutdown -h now lol. Yolo.

I tend to sleep on weekdays around 8'5 hours (from 1am to 9:30). On weekends I sleep usually 9'5 hours. I'm not on my 20s anymore. I don't wake up in the nights (unless I drink a glass of water before going to sleep, then I wake up earlier in the morning usually).

Edit: on summers I usually sleep one hour less (because it's too damn hot in the morning). I hate sleeping during the summer.

If I get 7.5 i'm solid. If I get less, on occasion due to kids or whatever, I will need to 'catch up' after a few days. I can survive on less, but I did lots of leetcode on low sleep and compared it to not on low sleep, and I can't solve algorithms as fast when i'm sleep deprived. I also can't focus as well. So generally, poor sleep for a software engineer is costly.

I recently turned 21 and I am sleeping between 6-7 hours but lately I feel like I'm wasting my time thinking that I could have woken up a little earlier, no matter how early I wake up. Maybe anxiety issues lately. Feels like running out of time while catching up with the speed the world is changing.
