Can you sleep forever without being in a coma?

I don't think so.  Sleep is a general term for four stages of brain wave changes: Stage 1 is the semi-conscious, sleepy feeling you have just before you fall asleep.  Stages 2 and 3 are dream states, and stage 4 is the deep, delta wave sleep that we need for our bodies to repair themselves.  Normally, at night we cycle through these 4 stages, even almost waking up which we just don't remember.  \n\nIn order to stay asleep and not be in a coma, you would have to "surface" to stage 1 and not wake up.  If you were in a place with absolutely no outside stimulation, you might stay asleep longer, but sooner or later, your body would develop aches (or bed sores) from laying down so long and that would be enough stimulus to wake up your mind.

I don't think you're passed out long enough. Plus I think you go to delta sleep and not rem sleep when you're unconscious, as opposed to asleep. I've only passed out once though, so what do I know.

It depends on thier physical and emotional fitness.  I have a freind that spent years in a Navy Seal team.  That guy could go many days of pure physical torment and shrug it off.  On the other hand, poor physical fitness and poor nutrition could be dangerous if someone went without proper sleep.  P.S.  The Seal I mentioned was a real mean guy without sleep.....but far from death.

No the body needs sleep in order to recoup. You can die without letting your body rest. If you get tired enough you'll pass out anyway..you will no longer have control over it

interesting question. I'm not sure I think it would depend on how you die. If it was something that would affect your brain like spine injury or stroke probly not but maybe if you have a heart attack your brain can still process for a few seconds while it still has blood that your heart stopped and you are dying. I do know that the brain can still work when cut off from the body (for a few seconds.) When they decapitated people they told them to blink until they couldn't anymore and the people would blink for almost 30 seconds after the head was cut off until they bleed to death. Kinda scary...

it isn't until we have had 4 hours interrupt sleep, that our minds can unwind....{ we must attain REM state of sleep...to process}\n\nthe body can go for days...\n\nbut the mind can not...\nso get it at least 5...and you will feel refreshed..

When you are live and kicking you are supposed to be a conscious person but who can become unconscious at times but once the LIFE goes out and you are declared DEAD you are no more conscious that is you become permanently unconscious!!!There is on in between stage called COMA(Vegetable) stage where your breathing goes on and you are kept alive by life saving devices but you do not regain your consciousness any more and the moment the life saving support is with drawn you become NON ALIVE or DEAD .\nThere is yet one more different stage where you are conscious but in a deep coma like meditation stage and alive too but you do come back to normalcy subsequently at your own will but may be oblivious of what ever happened around you or to your body even.You may even might have gone out of your body and returned back.Hindu philosophy says that one may leave the body and enter another body and then return back to old body.

No, and you're not unconscious either. There's a difference in the level of consciousness (how your brain is working) between when you're asleep, or if you've passed out and are actually unconscious. The simplest way of explaining it is that when you are asleep, you can still be easily awakened, for example, by a loud noise or being shaken. When you are unconscious, your brain is no longer processing external information - that is, it's still working, but wont respond to external stimulus.\n\nOh, and you don't dream while your unconscious - you do when you sleep.

Yes, they can. I hear lots of true stories about people waking up from their comas after they enter their unconcious state. For example, i heard on the radio that a woman entered a coma after she gave birth to a child. 20 years later she woke up and found her son all grown up. So in conclusion, it is possible.

Most of the time the body can do most anything you want it to. The problem is going to be the brain. You have to know how to do a "overload dump" so you don't over heat and go nuts.\n\nThen again, I could be wrong. I don't know your body, but 6 hrs sleep, and learning the rest of the time .... sounds like normal life to me (I am constantly learning).

yes- you sure can\nyou can even let wind, cough, and burp during sleep

You are your brain, but your brain is doing a huge number of things at once.  So while it has entered an altered state called "sleep", it's still quite busy, and not completely unresponsive.  It's not just dreaming, but still maintaining your body and processing incoming signals: you can ignore a loud truck on the freeway but still wake up when your child calls your name from the other room.  Or if your bladder commands you to......

NO!Also depending on your body. Sometimes it wont let you sleep

YES, you can die if you don't sleep.\nWhile there are no scientific reports of this happening in humans, it has been tested in rats.\nThey completely deprived them of sleep by having them on a small platform so that whenever they slept and thus lost muscle tension, they would fall into water, which would wake them up and then they would have to climb onto a platform again.\nIt took a couple of weeks for them to die being almost totally sleep deprived.\nTowards the end, their coats lost all condition, their appetite became really huge and yet they continued to lose weight at a fairly rapid rate. Eventually they died.\n\nSo the answer is yes, you can die if you don't sleep.\n\nHowever, it is extremely unlikely that this would happen to you. In any natural environment, you will fall asleep and recover long before you come anywhere near to approaching death. Unless you carried out a process on yourself similar to that used by rats, you'll be fine.\nThe world record for someone depriving themselves of sleep is a bit over 11 days in the 1960's and after he had been deprived for that long, he caught up on sleep and suffered no long-term ill effects.\nA few days of sleep deprivation won't kill you and you won't even tend to suffer from any bad effects once you have caught up on sleep.\n\nIf you do deprive yourself of sleep a lot, you will find that you will have lapses of concentration and will tend to sleep for a couple of seconds in what is known as a 'microsleep' and this will happen an increasing number of times the more sleep pressure you have.\nThis is why you should NEVER drive a car if you are feeling sleep-deprived. Or heavy machinery or do any tasks that requre sustained attention. You will have no memory of falling asleep at all and will believe you were awake the entire time. Of course, suddenly you'll be ploughing into a tree having fallen asleep at the wheel and never realised it.\n\nI hope that answers your question. If you want any more information, just ask :)

Sorry, but you can't wake the dead.  What you need to do is exercise the ones you have.  And dying brain cells aren't the problem.  Your brain cells start dying off when you're fairly young (I think around age 18), no matter what.
