is 5hrs sleep enough for an adult without any side effects?

It depends on the person.  \n\nJudging my the phrasing of your question- if you are subsisting on just 5 hours I would say it isn't enough.  (not being mean, just honest)\n\nMost adults need 8 hours or so per night.  As we age, we tend to need a little less or at least not be able to sleep that long.  Sleep recharges your mental batteries- I like to think of it as housekeeping for my brain- things always just make more sense when I have had enough. \n\nTo see how much sleep you really need, take a couple of weeks of going to bed early and not using an alarm.  After the 1st few days, see what time you are naturally waking up.  Average it, and that is how much you need. \n\nTake care of yourself!

I need around 6-8 hours sleep.  Anything less than 5 hrs and you can bet I'd be dangerously cranky and would be snapping at everyone the rest of the day, plus, I won't be up to any "thinking" tasks such as heavy analyzing and all that. I'd be on auto-pilot mode then until I get enough sleep. I usually wake up for bathroom breaks but I try not to turn on the lights (autopilot mode again) so that I can go right back to sleep without being woken up too much.

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.

Most of the people keep thinking that human being needs eight hours per day of sleep time. New researches have found that the perfect time to get really full filled is 7 hours. (Tibetans monks sleep just 4). So, let's say you want to wake up at 6 a.m. to get jogging and hour back home take a shower and get ready for being at the office at 9 a.m. The best time you can go to bed is 11 p.m.

Too much of anything is not good, even sleep.  Too much sleep will make you lethargic and can slow down your reflexes.  Just enough sleep (8 hours /day) would be ideal.

It sounds like you might not be getting quality sleep...see below....\n\nAccording to a poll conducted by the National Sleep Foundation, adults in America average 6.9 hours of sleep each night, which is slightly less than the recommended range of 7-9 hours. Sleeping gives the mind and body an opportunity to work. During sleep, the body does repair work by replacing old cells with new ones and re-energizing the organs and muscles. Also during sleep the brain is busy sorting through all the events of the day and storing the day’s learning into memory. \n\nThe quality and quantity of the sleep you get will determine how productive the next day will be. Here are some tips to help you get the sleep you need and deserve.\n\nEstablish and maintain a regular bed and wake time schedule, including weekends. \nDevelop a regular bedtime routine that is relaxing. Examples include soaking a hot bath or reading a good book. \nCreate a sleep inviting environment that is dark, quiet, comfortable, and cool. \nMake sure you have a comfortable mattress and pillows. \nUse your bedroom only for sleeping and relaxing. It is not wise to take work materials and computers into your sleeping environment. \nEat the last meal of your day at least two to three hours before bedtime. \nComplete your exercise routines at least a few hours before bedtime. \nAvoid caffeine close to bedtime as it may keep you awake. \nThe amount of sleep each person requires varies from individual to individual. When you get the right amount of sleep, you should not feel sleepy the next day. If sleepiness is creating problems in daily activities, you probably need more sleep. \n\nAccording to the National Sleep Foundation, the amount of sleep recommended, according to age, is as follows:\n\nInfants/Babies (including naps) \n0-2 months: 10.5-18.5 hours \n2-12 months: 14-15 hours \nToddlers/Children (including naps) 12-18 months: 13-15 hours \n18 months to 3 years: 12-14 hours \n3-5 years: 11-13 hours \n5-12 years: 9-11 hours \nAdolescents 8.5 -9.5 hours \nAdults/Older Persons On Average 7-9 hours \nSleep is as important to our health and well-being as air, food, and water. You may need to seek to advise of your doctor, if problems getting quality sleep last for more than a week and become bothersome or if sleepiness interferes with the way you feel or function during the day. \n\nDon’t deprive yourself of the precious sleep your body needs to stay healthy. Remember, when you get the right amount of quality sleep, you’ll wake up feeling fresh, alert, and ready to face your day.\n\nSource: The National Sleep Institute

1, max 8hrs sleep no longer. min 6 i would say. we do need our sleep and i suppose it also depends on the lifestyle of the individual. waking up between 5 and eight is acceptable but again subject to your life style. I wouldn't expect you to wake up in 2/3 hours now!\n\n2, there are web sites telling you how much you should eat, im not qualified enough to recomend though. Generally though a healthy diet will mean you small amounts frequently and cover all food groups. Try and keep things less toxic by avoiding processed foods and those unnecessarily containing loads of E's, soya is bad for men apparantly, and hydrogenated fats and also any other gobaldy gook that you dont understand in ingredients. Of course it ok in small amounts as preservatives.\n\n3, Generally start your day with a high carb cereal with a portion of fruit snack then protien/card meal snack another small meal. you should not eat after 7pm and make your last meal containg less heavy carbs.\n\nDrink loads of water. basically two glasses after a meal and lesurly in between as and if you need/want it. I only ever drink water nowadays, no other drink is better (apart from a yoghurt drink i have with my indian meals- mix 1 part plain natural yoghurt to approx 4-5 parts water).\n\n4, 30 mins of cardio is sufficient. it could be walking to/from work doing house work/chores basically somthing that gets your heart beating fast.\n\n5, as much as you want! but saying that i just saw a prog a few hours ago on ch5 in UK about sex addicts. dont let sex run your life otherwise it will ruin it. of course its a different matter if your job invovles it but apply the same principles out side of it if thats the case.\n\n6, ok i think i know what you mean here. routine everyday jobs are essential you cant get out it otherwise you become disorganised in other aspects in life as well. make these jobs enjoyable-listen to music use as one of your once a day cardio excercises if its hard working.\n\n(if you mean you have a boring job stick at it but keep looking for opportunities and something will meet you half way if you put the effort in to look for it. working is afterall essential for survival in a society. the alt is give up worldy goods and head east to india (asetics have nothing and yet have so much fun- a lot smoke green as well! or go to some budhist monestory)\n\nFinaly plan and look forward to going on vacations. I like to aim to go to places i've never been. however somtimes i just feel like going back to places where ive been before cus its good and i enjoy it there.

The multi-vitamin I take gives me lots of energy, I can go with as little as 5 hours sleep with no problems.

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.)

According to studies, minimum rest/sleep time must at least be 10 hours a day... If you don't, it might impair your judging abilities and affect harshly on your work... Also you are easily irritated if you lack sleep... 10 hours a day man... prioritize your own health rather than your job...\n\nHope this will help you...

Heavens no.  Everyone has different needs as to sleep.  Some people function wonderfully on 4 - 6 hours.  Others can't feel their best without 8 - 10.  You will learn what your body requires to feel completely rested as you go - it will change as you get older.

I know you said no medicine but I have a tip. I too am into natural healing but you need to regulate your sleep patterns in order to fix your issue. When the sun goes down someone with normal sleep patterns will have in increase in their melatonin. It is a brain chemical that helps us to sleep through the night. You may have a shortage of this for a variety of reasons. You can take a melatonin supplement 20min before you want to fall asleep. After taking this supplement for as little as two weeks your body will start to regulate it's own melatonin levels and return you to a normal sleep schedule. I take it every few years when I feel like my lack of sleep is negatively effecting my life. Give it a shot. It is totally natural and non addictive. \nIt may have many other uses and has been reported to make people feel better, strengthen the immune system, and reduce free radicals in the body. Current research is underway to determine it's effect as an anti-oxidant, immno-modulator in cancer, delayed sleep-phase disorders, and jet lag. So it is actually good for you!

9 hours is actually a very healthy amount to sleep. If you can, why not? 6 hours is too little

Caffiene will keep you alert when feeling tired how ever  you will need take more and more to fight the effects of tiredness, and it is also addictive. Another side effect will be a sudden crash if you dont maintian the levels in your body. One minute you will be awake and alert the next you will find that you have no energy and feel reallly tired. You should be aware that by working long hours at full alertness is detremental to you health over long periods of time. It disturbs your sleep pattern and causes you to become less alert. \n\nThere is also the practical issue of determining the level of fatigue at which performance poses a real risk. How do we set standards for fatigue? How much fatigue is too much? We recently compared the effects of sleep deprivation and alcohol intoxication and found that after 17-19 hours without sleep, starting from waking at about 0600 hours, individuals' performance was equivalent to or worse than at 0.05% blood alcohol concentration.15 In other words, commonly experienced levels of sleep deprivation—one extended day for a well rested individual—had a profound effect on performance. At around 2230-2430, well before reaching the circadian trough in alertness, performance levels were low enough to be considered incompatible with safe driving in many countries.\n\nThats an extract from the link below. I hope you work it worth the cost to you and your health.

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.

You should get at least 8 hours of quality sleep a night.
