   How many hours of sleep per day is healthy for a human? When I was in the army, they said 7 hours of sleep is sufficient. When I was in school, they told us to have at least 8 hours of sleep everyday. So, what's the number?

   The answer is not only is there no "correct" set number.  The need for sleep is going to vary with the age of a person, their lifestyle and their health.
   
   Most stressed adults get less sleep, but their circumstances actually would be helped if they got more.  Children who are actively growing need more sleep, and when adults become elderly, they start to need more than when they were younger.

   around 7-8 hours, but it really depends on each individual. Adults don't sleep as much, while babies sleep all day. Some people get off on just 4 hours of sleep a day and several naps during the day. What's also important is the quality of your sleep.
   
   "If you feel drowsy during the day — even during boring activities — you're probably not getting enough sleep. Also, remember that quality of sleep is just as important as quantity. If your sleep is frequently interrupted or cut short, you're not getting quality sleep." - mayoclinic
   
   hope this helped!

   Recommended hours of sleep are 6-8 hours. Naps are also recommended.

   It can differ for everyone....If you eat healthy, 9 times out of 10 you won't need no more than 6, maybe 7 and function well throughout the day

   It depends on your general health, age, and many other factors.  For instance, babies can sleep 18 to 20 hours a day because they need the sleep.

   There is no specific number, Azhar, as the others so rightly say.
   But there are averages; adults need either 6, 7, or 8 hours.
   Speaking for myself, I can't establish how much I need; it's always varied according to my circumstances. If I don't feel tired throughout the day, and fall asleep easily at bedtime, then I'm getting the exact amount of sleep I need.
   I saw an interesting documentary on this topic a couple of years ago. Apparently, according to statistic, the particular type of individual that NEEDS 7 hours lives longer. Of course, if I only need 6 hours, forcing myself to sleep 7 will not prolong my life

   A sound sleep ranging from 6 to 8 hours is perfectly healthy for the human body.  The sleep pattern differs from person to person.

    It's not the same for every person.  A few people do fine with 5 hours, and some need 12.  Most do good with 7-8.  The Army may have reasons for wanting to stick to the low side of the range. They tend to ignore the idea that anyone might need more than 8 hours sleep in trucking as well.  That's profit driven, not a scientific fact.  Schools don't profit from your lack of sleep so they can recommend 8 as a minimum.

    It depends on your age, level of exercise, and general health. Six to eight hours is a good range in which all five stages of sleep can be expressed adequately to refresh all parts of the brain. If sleep is extended beyond eight hours, it can result in a similar grogginess as if the person got too little sleep.
    
    Teenagers and those who exercise frequently require more towards the top end of that spectrum, as sleep is the period that allows for the most active growth and recovery.
    
    Adults are often comfortable in the six to seven hour range because they are done growing for the most part, and frequently don't exercise as much.
    
    The elderly also tend to require more sleep as it becomes difficult to stay awake for long durations at a time. This sleep is often broken up into naps during the day.
