http://en.wikipedia.org/wiki/Randy_Gardner_(sleep_deprived)......       That link is the world record for sleep deprivation. No you will NOT....I repeat NOT DIE from lack of sleep. You will die without food and water of course....Your body will eventually just shut down and stop. You will pass out...The record(seelink) is 11 days. I do know not sleeping enough wont kill you. Ive had too many friends that were chemically dependent....I'll just leave it at that

It's usually depression that causes insomnia, anxiety, and hyperactivity.  Although no one has ever DIED from lack of sleep, it's best not to let this slide. Our human body needs between 7-8 hours of sleep every night to function at it's best. Make an appointment fora physical with you family doctor and make sure you tell him/her about your problems.

Getting a good night’s sleep is an essential biological need. Without it, you can’t be your best during the day – at work, at home and in the car. Our behavior, moods, our ability to make decisions and even our eating habits are affected by the quality of sleep we get1. You can dramatically improve your quality of life by getting a good night’s sleep, which allows you to fully rest your body and your mind, so when you’re awake, you’re ready to take on all the things you need to on a daily business. LIVE LIFE! \n\nThe American Academy of Sleep Medicine \nreports that a majority of Americans say they experience frequent sleep problems and nearly 25% experience daytime sleepiness that often interferes with work and other activities. Left untreated, sleep problems can contribute to significant health problems, such as strokes, heart attacks, high blood pressure, clinical depression, diabetes and other serious conditions.

How do you define too much sleep? Every person has a different need of how much sleep is necessary to feel comfortable. Although there are average figures available, they are only a guideline but not binding.\nI recently saw a conversation on TV where a guy was talking about common prejudices in medicine. One of them was the amount of sleep. He said they found a significant connection between long sleeping hours and various diseases. However, it was the chicken and egg question. Meaning: do people sleep a lot and become sick because of that or do sick people need more sleep?

It's not worthless . . . just not as beneficial.  Even a few hours sleep will recharge your muscles as well as increase blood flow to your brain.  But, REM sleep is necessary.  Go a day or two without it and you will begin to suffer memory loss, poor concentration, and difficulty completing simple tasks.

Our cells do not sleep.  The function of cognizance shifts from the real world to the dream world.  Yes, as we expand our knowledge our capacity to learn increases.  It is a false notion that there is only so much "space" in the brain\nWe all function far below or mental capacities.

depends on how old you are, but basically no. you have to sleep at least 9 hours so if you wake at 7AM that's marginal...

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!

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.

Proper rest is real important in maintaining healthy weight.  I have sleep apnea. and it greatly affects my weight.  Also it is a tremendous stress on my heart, due to the extra weight and the "stopped" breathing during the night.  It is also self full filling, I am so tired during the day from lack of sleep it is hard to exercise.  And I have to have a nap every day due to being so tired all the time.  \n\nBTW:  My family is quite thin, I developed the sleep apnea and have been fighting weight gain ever since.  I was thin even after giving birth three times, developed sleep apnea after.\n\nPeace.

Yes, the brain never sleeps. There have been many studies of Rapid Eye Movement. It makes no differance what your physical handicaps are as long as your not on life support and listed as "Brain Dead".

why on earth would you want to go without sleep when the consequences of hnot getting enough REM, at worse could be death lol!\nIf its for studying etc then coffee can help to a degree but you need to realise that drinking stacks of anything that is caffiene based can affect your heart so thats not good either.\nExersize can make you less drowsy and lethargic too but it needs to be steady exersize rather than majorly frantic ...\nif you have concerns that you are getting too much sleep then go see your GP
