Normal human being have 6-8 hours sleep in 24 hours and its better if one have this duration in a stretch. If your required quta is fulfilled then its psychological factor that you feel asleep all the time. Try to remain busy and have some productive and positive hubbies. By the way, why you laydown so many times?

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

If there is 24 hours a day, I have to sleep 8 hours, so there will be 16 hours left. From 16 hours, I'll spend 8 hours studying, 4 hours watching television, 2 hours having fun and with the 2 hours, u can do what ever u want.

everybody is different. I found out that some people can get by with 6 hours while others need 10 (average 8.) I'm in the 10 hour range, so I have to sleep around 10-10:30.

yes you can but it sucks.........your brain re charges after 4 hours of sleep, the other 4 are for your body, but your body can function on a half charge, so if you sleep roughly 4 hours a night that's all you really need to keep from getting nerve disorders and shit like that witch will kill you, Ive heard that a person will die if they go more than 4 days straight with out sleeping. Also, I dint know how long they would go but I have heard the Nazi's would force Jewish prisoners to work until they died from exhaustion.  \n\nI myself have conditioned myself to the point that I could stay awake while driving after 4 and a half hours sleep each night for a week, but the tax it in poses on the body is not cool. After about a year and a half I became allergic to the sun, doc. said that it was because one of my origins was increasing the out put of some long named chemical that I cant pronounce or come close to spelling, all thanks to a lack of sleep. my doc. recommended at least 6 hours of sleep each night, I sleep 6-7 hours and stay healthy

Schools used to say seven to eight hours.  Now they are saying eight to nine hours.  I feel you should sleep as much as you feel you need to.  sometimes I only need to sleep three or four hours... sometimes I will sleep eleven hours.

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

Oh ya, me too as healthcare provider, I work 12 hours a day. I'm used to sleep late at night, with wakeful hours since my boyfriend calls me from time to time from work. He work night shift, so more or less, I get 4 to 5 hours of sleep daily too except my off days, which is the happiest days of my life because I can take enough rest and sleep. I can even sleep 12 hours during my day off to catch up those days I lack sleep. We need enough sleep since lack of sleep below 6 hours a day will lead to serious heart problems as what I've read in the internet.

Not enough in general. We need good six hours sleep .\nAlso your age sex your physical conditions the type of work , all play a role. How can I pilot or driver be continuously exposed to short periods of sleep and endangering the life of many.\nIf you are enjjoying holidays and watching WORLD CUP FOOT BALL MATCH DAILY LATE IN THE NIGHT AT PLACES LIKE ASIA then less sleep, intemittent sleep during night and a day time nap is ok. You cant help it. We get to watch such matches once in four years and there is thrill in watching LIVE not recorded and replayed

A healthy adult, from ages 16 to 38 or so can get by on about 4 hours of sleep a night.  However, it is reccomend you get from 6 to 7 hours of sleep.  8 hours of sleep was mandated for many years, but found to be non optimal.\n\nChildren under the age of 16 should get at least 8 hours of sleep or more.  Infants and toddlers, preschoolers and such should get more than 10-12 hours of sleep per day.\n\nOlder adults from ages 38is to 60 should get about 8 to 10 hours of sleep per day to help their bodies recoup the daily losses.  \n\nOlder people, from ages 60+ should usualy get from 10-12 hours of sleep a day to help recoup the losses.\n\nMind  you these are optimal hours, the range can be decreased and increased based on the activeness of the person.

It depends on the individual, but most teenagers need 8 or 9 hours of sleep, so I'd say by 10:30 pm.

Eight hours is plenty of sleep.  Most teenagers get MUCH less than that, but for most adults and teenagers, the recommended amount is 8-10, I think, and it varies from person to person.\n\nGetting too little sleep, of course, leaves you tired through the day.  However, it is possible to get too much sleep (although that seems IMPOSSIBLE to those of us who are sleep deprived), and that can leave you feeling groggy and wishing you had more.\n\nIf you're waking up feeling rested, you're probably just fine.  You may want to talk to your doctor (or a trainer, if you have one) to make sure, or if you are waking up still feeling tired.

Eight hours of a restful night and 10 hours in the bed if you wake up one to two times in the middle of the night............The sounder you sleep the less slept you need................Even six is good if you have a peaceful nights sleep.........................

To get more energy. If you don't you will get in Sleep debt. Also your brain, reflexes, and body would not do as good. When you are in sleep debt you have to sleep more to get back on track. Also the recommended hours of sleep are 8 to 9 hours.\n\nFor kids they need 10 to 11 hours of sleep.\nAlso Dr. Know (from TV) did tests on a lab rat (Not a rat but a human) by forcing them to only get 4 hours of sleep each night and did a test a found out their reflexes were slowing, their memory test wasn't as good, and when they recovered (pay their sleep debt) they did better.

i know it's lame, but try sleeping a little earlier. if you're not staying up for something important, sleeping earlier will help. make sure you're getting enough sleep for you. it's not necessarily 8 hours, but however long your body needs, that could be 6. you can feel tired if you get too much sleep. try waking up at the same time every morning to regulate you sleep cycle. make sure you're comfortable while you're sleeping. and try not drinking caffeine from late afternoon and at night so you don't have problems sleeping.

You can only catch up on lost sleep by about 2-2.5 hours a night.  Then only for a few nights in a row.  Trying to make it up all at once will leave you groggy.
