Studies show that the number of hours is not the main factor - what is more important is the number of complete sleep cycles. Each sleep cycle lasts an average of 90 minutes and contains five distinct phases, which exhibit different brain-wave patterns: 65 minutes of normal, or non-REM (rapid eye movement), sleep; 20 minutes of REM sleep (dream state); and a further 5 minutes of non-REM sleep.  The REM sleep phases are shorter during earlier cycles (less than 20 minutes) and longer during later ones.  If we were to sleep completely naturally, with no alarm clocks or other sleep disturbances, we would usually wake up after a multiple of 90 minutes, e.g. after 4.5 hours, 6 hours, 7.5 hours or 9 hours, but not after 7 or 8 hours, which are not multiples of 90 minutes.\n\nA person sleeping only four cycles (6 hours) will feel more rested than someone who's slept for 8 to 10 hours but not been allowed to complete a cycle due to being woken up before it was completed.\n\nI have also heard from various sources that scientists are developing a new type of alarm clock that would detect the phase of your sleep and wake you when the current cycle is complete, so as not to disturb the cycle and ensure that you are as fresh upon waking as possible.  (I heard this over a year ago and have been waiting for its release, as I have a medical condition that means I am almost constantly fatigued.)

This depends on each person. I only want/need eight hours. Mrs. Thatcher (and others) famously needed only four hours. I knew a girl who regularly had twenty-two hours. None of these people thought they were getting "too much" sleep. They simply slept the amount they felt they needed.\nWithout medication and assuming good health, I would think the body naturally wakes when it has had sufficient sleep.

I get about 8hrs of sleep. I go to sleep at about 10pm and wake up at 6 am, but thats only because its my senior year (17 years young)of high school and I have like the easiest classes everrrr. Even with my two AP classes I finish homework so quickly. The last 3 years of high school I had alot of homework though so I usually went to sleep like at 2 every night. and got about 4 hours of sleep.

Day person, definitely.  I get up for work each day at 4:15 AM so even on days off now, when I get up at 6 AM that feels like sleeping in.  But I'm beat and ready for bed by 9:30-10:00.

The guidelines on how much sleep people need are just that - guidelines. They are not one-size fits all, and different people need different amounts of sleep. If you are in good health and don't feel tired, then consider yourself lucky to need so little sleep. I seem to need around 8-10 hrs, which is a total drag and dosen't fit into my schedule at all - I wish I had your "problem" :).

Most people recommend at least 7 1/2  to 8 hours.  It depends also how old you are, sometimes older people get by with less sleep.  Look at it this way, if you get a certain amount of sleep then wake up, and you still feel like crap, you need more sleep.  Most important too is if you wake up in the middle of the night, DON'T look at the clock, it will psyche you out and you won't fall back asleep as fast.  Also try to go to to bed and wake up at the same time every day, or at least don't vary the sleep/wake up times by more than 2 hours (for example if you normally get up at 7am, don't sleep in longer than 9am, regardless of the time you went to bed), that's the maximum difference your body can take. Also don't drink ANYTHING closer than 3 hours before you hit the sack.

The most anyone can sleep is most definitely NOT 8hrs. I have had friends who slept for 24hrs straight. It all depends on how much of a "sleep deficit" you have. \nYour body needs a certain amount of sleep, and that differs for everyone. However, it is recommended that we get around 8hrs per night if we are to function at our best. \nSleep is important for many reasons - helps with "solidifying" your experiences and memories that you have from the previous day, recharges you with energy - I think it's pretty obvious. \nAbout the day vs night sleep? It is best to sleep during the dark hours because the production of MELATONIN - a hormone that regulates sleep-wake cycles - varies with exposure to light. \nI also happen to be "nocturnal", but this is causing me a lot of problems. I cannot imagine how it would feel like to wake up feeling refreshed before 11am!

It depends on your daily activity.\nSince I haven't been exercising lately, instead of sleeping 8 hours and feeling refreshed, I've been sleeping 14. Not normal of course.\n\nJust do something all day and set yourself up for what time you go to sleep. Normally go to sleep at 10 and wake up at 6 A.M.\nMost people do that, if they have jobs.\n\nMight wanna go get some exercise and go to the doctor.

That varies but I tend to be tired all day if I don't get at least 12 hours of sleep.

For most adults, yes.  I think a lot of people sleep too much, either because they are avoiding life, or because they are wearing themselves out in the daytime.  Did you know, by the way, that if you nap in short segments, you need less total sleep time?  Try taking a nap soon after dinner, for an hour or two, and then stay up until you are really sleepy.  Even if you have to get up to an alarm clock in the wee small hours of the morning, you will probably be more refreshed than if you went to bed approximately 7 to 8 hours before the alarm is due to go off.\n\nRemember, too, that wake/sleep cycles are as individual as everything else about human beings.  We can learn something from the ways of others, but ultimately we must each find what makes us feel the best.  Life is an experiment, and you are your own guinea pig.

There will be times in your life when you will need 12 hours and it's no big thing.  Your body tells you when you need sleep, and if it's at all possible (like not at work or driving, etc.) then listen to your body.  When you sleep your body rebuilds itself.  Just don't over-do it night after night with that much sleep.  Normal needed is about 8 hours a night.  But you can play catch-up sometimes.

The truth of the matter is that nothing may be wrong with you!  The amount of sleep needed varies from person to person with the average needed being 8 hours.  Some can get by on 5, others need 10 or more.  Since you have no symptoms of illness, are not depressed and you've always required a lot of sleep, this must be your "normal".  Nothing to worry about!

Wake at the same time everyday, even weekends, and your body will adapt within a 7-10 days. Research has shown that sleeping in on the weekends does more harm than good.  If you need extra sleep go to bed 1/2 an hour earlier every evening.

Im 33 and look no older than 24 and I never sleep for anymore than 5-6 hours a night and work at least 9-11 hours a day.\nI think its more in your genes and not smoking.
