Poll: How many hours do you sleep?

I sleep 3-7 hours per day (so average 5), I think it's bad for my brains and health in general. What about you, what's your average?

8-10 hours

I spent years in a mildly sleep deprived state, then I started sleeping 8+ hours and became 2x more productive. I recommend it to anyone who feels like they need a nap midday.

What a terrible breakdown. How is 7-10, which is what I imagine the majority of people sleep, a single category?

Try something like: (< 4, 4-5, 5-6, 6-7, 7-8, 8-9, 9+)

7-8 for sure. Anything less for a sustained period of time and I lose a ton of productivity.

I was seriously considering going on a polyphasic sleep experiment for a while to cut down on the hours, but after doing a lot of research it didn't really seem legit. Does anyone here have any real experience with polyphasic sleep?
