Sleep Duration Needs

Try the same logic : 4 hours sleep for a week/2 weeks and see if your statement is still valid.

Usually 10 hours a night. It's super annoyingly long, but that's exactly how long I seem to need. It builds up some sort of reserve of energy so I can do all nighters when necessary, but if I go too long without 10 hours I will become super unproductive. Naps help mitigate the effects of less sleep, but definitely don't help all the way.I'd be interested to know why I have to have so much sleep - anyone else need 10+ hours? My hunch is that I sort of operate at full-tilt p

Something that took me an embarrassingly long time to figure out is that I don't need 8 hours sleep every night, just on average. The correct sleeping time turns out to be half the time I was previously awake for.

Wow, less than 6 hours of sleep. Is that sustainable?

What works for you isn't necessarily what works for someone else. 4-5 hours a night turns me into a zombie after about two days. My optimal duration seems to be about 8.5 hours, up to 9 hours if I heavily exerted myself the previous day.

Get enough sleep. I need 9 hours most nights.

I wish I could get by on four hours of sleep a night. But my body just doesn't cooperate. If I get less than ~7 hours of sleep over a period of a couple of days, I start to feel absolutely miserable and can't sustain it. I seem to function best on 8 hours, but I can survive on 7. I can do less than 7 for a couple of days in a row, but not consistently for long periods of time.It's depressing, because I would love to use those hours for something more productive than sleep, but what

Maybe look into polyphasic sleep. Instead of sleeping continuous 8 hours you can have main sleep chunk with short naps sprinkled throughout the day.

I need 8 and often more like 9 or 10 hours of solid sleep each night. If I'm well-rested, one night of 6 or 7 hours doesn't affect me, but it can't happen repeatedly. We may both just be outliers.

The no sleep is tough for me. Historically, I've required about eight solid hours. Lately, I've found that with a morning exercise routine I can cut about two hours out of my night's sleep and still function fine. Anything less than six hours and I start to require a power nap during the day.
