Sleeping for 15hrs is too much.If you think it is because of your work then try to reduce it and do what is important.\nInstead of sleeping longer you can also do YOGA which will help you reduce stress. And also consult a doctor to check if it is not a serious problem.

if you are normally active you need 5-7 hour total sleep during a 24 hour period. limit your naps to 20 minutes or you will feel sleepy the rest of your day or night. if you are not active you could probably stay in bed all day and night. get some fresh air and some sunlight

Because having 13 hours of alseep, can be worse than having 7, depending on your age, you should hit exactly the amount of sleep you need, and you will wake up just fine, like one time i fell alseep at 3 o clock in the afternoon, woke up at about 11:30, and i was wide awake, becuase I convieniently hit the time to wake up, but then i fell back asleep to about 7, and i felt horrible, like I stayed up 10 days in a row, so try to time your sleep perfectly there is an algebraic question somewhere on the internet, but if your young, about 9 hours. if your a bit older 8, and if your very old, about 6 and a half, try to find it its like S=a*2.6937 dont ask, but its sometheing very simaler to that, i couldnt find it :&#92;

Most peoples' normal sleep cycle lasts 90 minutes.  When you first fall asleep you are in a light sleep, then you go deeper into sleep and back to a light sleep after about 90 minutes.  The longer that you are asleep the shorter your cycles are.  If you slept for 3 hours, you probably had two full sleep cycles and awoke naturally when you were in the lightest stage of sleep.  When waking from this stage of sleep you feel most awake and refreshed.  If you are awoke from a deep sleep you will more likely still feel tired.

No, only if you are sick, then it's normal if you sleep all day and night, or at least nap all day. Even if you hadn't slept much recently, that's too long to be considered normal.\n\nIf it only happened once I wouldn't worry about it!

7 to eight 8 hours and if I get less than 6 it makes for a really long grouchy day,but cant ever seem to sleep more than 8 unless I have a hangover.\n   or cuddling next to that perfect little beaty queen

For healthy adults, 5-7 hours of sleep per day is what is required.\n\nIf however, you are not a healthy adult, and you sleep for less than 4 hours per day, then your chances for medical problems dramatically increases.

You sound exactly like me.  It is now 4:07 a.m. my local time, and I will probably be up another hour or so.  I just cannot get to sleep any earlier.  It stinks because I want to sleep past noon.  I have always been a night owl and not a morning person, but this is getting to be ridiculous.  I am also thinking of seeing a specialist.  I don't do well on 8 hours of sleep.  I also need about 10.  Good luck!

Nope. BY THE 15 does not include the 15. If you say you want to go to bed by 12, does that mean you would stay up until 12:59?

i've heard several times that the amount of sleep each individual requires is based on a number of factors, some of which include age, weight, and even diet. everyone has different schedules, and each one is independent to one another depending on their own individual health.<br />\ni'm not one to set an example, but i average anywhere from 5-7 hours of sleep on a regular basis. sometimes my body requires more, sometimes less, but it seems to balance out and i never feel as though i'm suffering from lack, or over abundance, of sleep.<br />\ni've included a yahoo! health article to help shed light on some of your own personal sleep habits.

You're gonna have a lot of problem functioning normally if you don't sleep at least 6 hours a day. Your body needs to rest otherwise you'll be more prone to sickness. Also, people who don't sleep normally tend to be more irritable and their brains don't function properly. You'll be able to maximise your days if you sleep well. :) Take a long bath, relax, listen to some soothing music, and snooze away...

Maybe you have had enough sleep. Einstein averaged 3 hours a sleep a night ! I don't always sleep well, but sooner or later my body catches me up on needed sleep.
