Is there anything wrong with splitting up your sleep into two separate chunks a day?

Go with what works for you. This may interrupt your life later on after college but for now just sleep when you want

Totally individual and different..\nAlthough there are some standard recommendations, deviating doesn't mean it's bad.\nI know a lot of people who only sleep 4-5 hours and don't have any problem while others are unbearably grouchy if they only had 8..\nIf you can rejuvenate on 15 minutes naps, you surely need less during the night..

Body need 7-9 hours on average -- If you are getting less then that once in a while that will not hurt you. But the sleep you do get is it consistent - if you wake up a lot during rest then there might be a problem

It is supposed to be really good exercise, personally I don't think you can have too much, as long as you are only having it with one person and not sleeping around, I think it is fine.\n\nIf it is you you are talking about I think you are a lucky $£&*(**!"£$!^$^

I think that everyone I know has an addiction to my space, you should limit your self to 3 checks a day... Waking up in the middle of the night is compulsive behavior, you need to take control of yourself. You can do it.

no, its just not good to do it too much, because you need a life besides doing it, 1-3 times a day is probably healthy enough

Many people would reply by saying a minimum of eight hours of rest. But the answer doesn't depend solely on how many hours you log in bed. Night after night, you need deep uninterrupted sleep in a bed that provides adequate comfort support and space. What matters most of all is how you feel in the morning. If you wake up full of renewed energy, you've had a good night's sleep. \n\nThere is no one formula for how much sleep is enough for you. Expecting all people to need the same amount of rest would be as absurd as expecting them to eat the same amount of food every day. Each of us seems to have an innate sleep "appetite" that is as much a part of our genetic programming as hair color, height and skin tone. Normal sleep times range from five to ten hours; the average is 7 1/2. About one or two people in one hundred can get by with just five hours; another small minority needs twice that amount. \n\nHow much sleep is enough for you? To figure out your sleep needs, keep your wake-up time the same every morning and vary your bedtimes. Are you groggy after six hours of shut-eye? Does an extra hour give your more stamina? What about an extra two hours? Since too much time in bed can make some people feel sluggish, don't assume that more is always better. Listen to your body's signals and adjust your sleep schedule to suit them. \n\nKeep in mind that sleep needs change with age. And the older you are, the less total sleep time you may need. A newborn may spend 18 hours asleep. From infancy to adulthood, sleep decreases by more than half. Throughout the middle decades of life, seven or eight hours of sleep generally are needed to provide adequate rest. For older individuals, six hours may suffice.

This really depends upon the person.  As a general rule of thumb, it does have an impact and is sometimes associate with personality and sleep disorders.  But this is not a hard and fast rule.\nIf sleep is like the body’s pit stops in the rat race of life, then avoiding pit stops when you need them will only lead to unscheduled stops later.  With any luck you will not crash, or worse, crash and burn.

Yes and no.  You can not build a "stockpile" of sleep.  However, your body can accumulate "sleep debt."  The amount of sleep each person needs varies.  In addition, how your body addresses it's sleep debt depends on the circumstances.\n\nLet's say, for example, you need 8 hours per night.  If you have zero sleep debt, you will not be able to sleep more than 8 hours.  But if you sleep for only 7 hours one night, you add 1 hour to your sleep debt.  If you do this Sunday through Thursday night, you will have 5 hours of sleep debt.\n\nThe catch is, most people can not relieve themselves of more than about an hour of sleep debt per night.  So, even if you sleep for 10 or 11 hours on Friday and Saturday nights, you would most likely not make up for your lack of sleep all week.  The quality of sleep diminishes with each sleep cycle, so those last couple of hours aren't nearly as effective as the first few.\n\nMost people are carrying around sleep debt.  In fact, it is healthy to have a small amount of sleep debt (say, 5-10 hours).  If you have too little, it is difficult to fall asleep at night.  If you have the right amount of sleep debt, you should not feel tired during the day but it should only take you 10-15 minutes to fall asleep at night.\n\nHowever, generally speaking, there is a cap to the amount of sleep debt you can accumulate.  If I remember correctly, it is at about 50 hours or so.  The average person is walking around with about 25 hours of sleep debt or so.  Many sleep specialists believe that a large portion of auto accidents have a root cause of lack of sleep, but it is difficult to accurately measure this.  50 hours of sleep debt has a similar impact to your ability to function as if you had just finished off a couple of beers.\n\nThere's an excellent book on the subject called "The Promise of Sleep"

This is an interesting one which I think depends on what we THINK we need. Most folk in UK seem to generally consider we need 8 hours or thereabouts. I joined a group once which stated that if you needed more than 4 hours there was something the matter with you. This struck me as quite ridiculous on first hearing it but I gradually realised that our perception and conditioning are an enormous influence. I now KNOW I can manage quite well with 5 or 4 hours but have the capacity to sleep for 12 hours too. I am truly blessed to be able to drop off almost the minute my head touches the pillow.

An hour or two of personal time is a good thing for me. So yeah, a slightly different schedule would be nice to have.\n\nGood question.

don't know about that, but I know it can affect your mood and how well you react the next day.  You actually need proper amount of rest.

its healthy to have at LEAST half an hour a day. if you want to be tone or really healthy then you will want to do an hour or more.

Why do you have this obsession with weird sleep habits? (I just answered another of your questions regarding sleep.) Sleeping with your eyes open would be bad, since your eyes could dry out. As for sleeping standing up, I doubt that would be very good either.

of course it is!  Any exercise is better than no exercise.  A good workout a couple hours before bedtime might help you sleep better too!

No -the person is still getting 7 hours of sleep.\n\nIt really doesn't matter what time of night - or day - you sleep, as long as you are getting at least 6 hours of sleep.\n\nThe only thing it might be bad for is your job if you're supposed to be there at 8 am.

twice a day for ten minutes
