Some of us have mastered the art of sleep-posting - or borrowed a trick from whichever it is of dolphins and sharks, and only sleep with half our brain at a time...


More seriously, there are regular posters here covering a wide range of time zones, so there'll probably be an uberpuzzler awake at any given moment (not necessarily logged in though) and it's an accepted fact that some people just plain require less sleep than others (or at least get by with less)

yeah, what new thing do you introduce to us? wait, there's the dictionary. i see. Yup, i get buy with 10 hours of sleep/month. But i think it's only because my inhumanness disables my need want sleep function untill i have absolutely nothing left to do, for until i have nothing left to do, i feel like i've had a bucket full of sugar and, although i visit this site regularly, i still get the absolute most out of life possible before sleeping, so it isn't really one of my hobbies

Maybe "sleeping pattern" problems will be the only kind of problems that will stump the uberpuzzlers here!!  ;) ;D

Deep bonus question: why do we sleep?
Title: Re: Sleep
Post by rmsgrey on May 17th, 2010, 7:00am
One theory is that sleep evolved in order to reduce wear and tear on our bodies - if you don't need to be active at that moment in order to improve your survival chances, then being active is all downside - you burn through more food, you have an increased risk of injury, you stretch or stress various body parts...

Of course, nature being what it is, once you are sleeping regularly, it gets adapted for other purposes - a lot of mental filing and organisation appears to happen during the periodic downtime...

Did it evolve? Do amoebae think that sleep is for wimps?

I read somewhere that our physical bodies can get by without (very much) sleep. Along with REM, 'mental filing and organisation' happens during dreams. But I seem to rememeber that dreams comprise only a small percentage of the time spent asleep. During dreams we still seem to retain our sense of self. How about during deep sleep? What's going on during deep sleep? The alpha waves of deep sleep are similar to those during meditation. Of course, we are fully aware during meditation.

I don't think amoebae think :P (But then, if that's true, they don't think I think either, so that's fair enough.)
I think it sounds plausible that it is adaptive in the way rmsgrey says, and that that has contributed to its evolution. I don't know if there's much research about how sleep evolved though. And dolphins (http://www.newscientist.com/article/dn17059-brainjuggling-lets-dolphins-avoid-sleep-deprivation.html) seem to sleep one brain hemisphere at a time, which is peculiar (but understandable, since drowning is not very good for one's survival).

Going without any sleep is lethal, according to this article (http://www.newscientist.com/article/mg20627562.100-maxed-out-how-long-can-you-go-without-sleep.html). Or at least it is to rats, if they're kept up for two weeks. And there are occasionally news stories about gamers staying up for two weeks and dying.
Not sure about how far you can reduce the need for sleep. But I think there are drugs you can take to extend the amount of time you can stay awake without suffering adverse consequences (and I don't mean coffee).

I'm not quite sure what you mean by a sense of self here. I dream about being others often enough, even switching characters randomly without noticing it till I wake up. It's not typically like a lucid dream, where I'd actually have any control about my actions or perspective. I'd say my sense of self is rather impaired during most dreams.

Right, you start getting psychotic on about the 3rd or 4th day. (Yes, I'll try anything twice.)

While one's sense of self is severely impaired during dreams, I think it nevertheless remains to some extent.
In contrast, our egos do not exist during deep sleep.

I never dream about being others. I guess that's just me.

So what's the longest that you guys have been without sleep ? The longest I had was 56 hrs. The most mind numbing experience of my life..added to the fact I spent a huge portion of that time in the jungle with the barest necessities to survive. And the instructor somehow see fit to give us loaded with live rounds M16 after 36 hours of no sleep for target practice. Hmm..

I don't think I've ever went without sleep for longer than a day. Which hasn't, however, stopped me from the occasional being sleep deprived; I don't do well without a full nights sleep.

I skipped a night a few times when I was young but I went to bed early afterward.  So maybe 36 h max.
Now, even missing half a night gives me a headache the next day.  So I don't think I will ever try to improve my record.

Back in college I pulled back-to-back all-nighters one semester studying for finals, so that's something like 60 hours, and I was still lucid enough to do well on the tests.  The worst, though, was, a few years later, trying to finish a project on-deadline for a commercial launch, I spent a week sleeping only every-other night: that's four straight 40-hour days.  That was brutal, and I was pretty loopy by the end.

In my student days, I did 40-hour stretches on occasion.

I've also been known to sleep (more or less) for up to 16 hours.


As for whether sleep has evolved, the alternative would be that sleep has been static and unchanging ever since it first appeared - it seems much more likely that sleep has been, and is still, evolving slowly, like most things about living creatures...

hello my friends to you :) i am computer science research, working in the area of ubiquitous computing. Share your thoughts if you are familiar with this field.


well , for best and fresh mind i suggest 6-8 hours sound sleep. This helps over come on the pressure we face during the routine life.
