Hey guys, I was wondering what your sleep schedules are like. I work graveyard shifts, generally around 11pm-7am, and I was wondering what the minimal amount of healthy sleep a guy can get and still perform daily tasks without issues, long term. The internet says "sleep at least 7 hours per day, not enough sleep is unhealthy, 8 hours ideal, etc., etc" but I was hoping for actual data and experience from real world people. Most of my coworkers that I asked actually sleep twice a day (including myself), and it is mainly because of the schedule for the job, apparently. I used to sleep once a day before. Now, it is a split 4-5 hour and 2-3 hour sleep schedule that I am on, and after numerous months of this, who knows it might be permanent now.

Also, what about that uberman and ultraman sleep schedule? Anyone actually try that? I get the sense that those programs don't really work, or if someone trys it out, they can only do so for like a maximum of a couple of weeks or so. Otherwise, it would be much more popular and everyone would be doing it or talking about it. But anyway, give me some feedback. What in your experience is the rock bottom amount of sleep a man can get, long term, and still be able to function well? What is your experience?

I typically sleep about 4-5 hours (2am to 6am ish) . I don't know if this is healthy or not. I do not think that it is infinitely sustainable without supplementing with other naps or something elsewhere - but for now it works, and I am generally able to function without noticeable declines in cognitive or physical ability.

I leave for work at 4AM.  I usually go to bed at 9-10PM, then I take a 1-2 hour nap when I get off, so I'm biphasic.  Polyphasic sleep patterns do work, but take a while to get adjusted to.  I took me about 2 months to get adjusted to biphasic sleep.  

The plural of "anecdote" is not "data." The Mayo Clinic and WebMD are reliable sources for health information online.

Dr. Mom strove to get 7 hours of sleep each night when I was growing up, but she also worked full days on 0 sleep. She'd trained for it. I don't know how much sleep she normally gets now, but once or twice a year she still has nights of 0 sleep. [She's an obstetrician.]

Parents can better speak to what happens once Dr. Mom's work is done and her patients' work at home begins. The mommy blogs are split between "I've never been this tired. I don't know how I'm surviving" and "Your body adjusts." When Mom had my baby sister, she was hallucinating due to lack of sleep the first few days at home.

I struggled with insomnia through school and have certainly functioned in the classroom and to some extent at work on very little sleep. I only consider myself safe to work or drive if I've had 6 hours' rest, though. And on a recent road trip for work, I discovered I might need more.

The Benedictines created and preserved Western Civilization sleeping from 1-4 twice a day.

Sleeping twice a day is healthy and how we used to sleep before electric lighting.  People would naturally do this if they where allowed to.

The real question is are you getting enough sleep in both periods to match your needs.  You may also find that you sleep better if the sleep times where in factors of 90min.  So 4.5 hours and 3 hours or some such.

Look up Science Friday on the web they had stuff about sleeping recently on their show.

I sleep a lot, and I think it's helped me stay pretty healthy at my age.  I also lift weights intensely three times a week and have a job that keeps me jumping physically, so I make sure I get all I can.

That means 7.5 hours a night and a half to full hour nap added when I get home from work, every day.

I did post a nap post here about two years ago; one guy in the military responded he got by on long posts where he could not sleep by taking ten-minute naps whenever he could get them, and that way he could go on indefinitely without a night's sleep.

I get the full 7-8 hours probably 5-nights a week.  5 or 6 the other two.  I don't nap, though ... takes me a good long while to fall asleep.  My wife is an early-to-bed-type ... so I'll usually go off with her at 9 or so, and watch TV in the bedroom.  I don't usually fall asleep for a couple hours after that.
