Ask HN: How many hours of sleep are you getting?

I feel like I lose productivity if I get less than 7 hours of sleep a night. I can't think as clearly and can't process as much information

8-10 hours.

Anything less than 7 and I get "brain fog." And my day is essentially ruined. Hard to be productive when your mind is mush.

Cannot tell if I am the strange exception or if only the exceptional cases (e.g. 5 hrs etc) are posting here. Kind of like asking people their height, only the people who are the extreme end of the spectrum give an answer and the whole thing looks warped.

I spent years sleep deprived. Sleeping around 6 hours per night. Sometimes working 36 hours non-stop. Deciding to get a solid 8 hours every single night was probably the smartest thing I've ever done for my productivity and sanity.

The other night I fell asleep at 6pm, woke up 4 hours later (10pm) then done some work until about 4:30am and caught 3 hours sleep and I felt great the next day. It was really weird, felt like I was up all night but wasn't tired at all the next day until late evening.

Anyway, I usually get 6 hours on weekdays and feel crap for an hour before brushing my teeth etc.

It would be interesting to try and link these numbers to some form of productivity / successfulness metric.
