How much sleep does an average person need for proper health maintenance?

future doc

I know that recieving 9.5 hours of sleep restores a person immune system, and at least 8 hours guide in effective anabolic activity as well as neurohormone effectiveness. But i find myself quite educated in general biology and medicine, but unfortunately do not know that much about sleep. Any accurate information would be helpful, please get into as much detail as possible in your own words, do not copy adn waste from wikipedia or other sources, as i can do that myself. Thanks.

a normal grown up requires 8 hours of sleep. oversleeping does no good either. but every individual needs more or less according to his/her own needs, we r all different after all.

Well I have a 2 year old who wakes up frequently through the night. When she was first born I sometimes went 48 hours with no sleep. Now she is a bit older I get about 4 hours per night and I have to go to work the next day. I think I'm use to sleep deprivation since having a child

But for me to feel fully functional I need at least 8 hours sleep. I was told by my GP this is what I should be getting! Hahaha if you have a child who doesn't let you sleep!

I think that it depends on the person. Your body goes through stages as you sleep and it is random for everybody some people need 5 hours other need 10 hours. My machinist teacher sleeps 3 to 4 hours a day while one of my friend sleeps around 12 hours a day(which i think is too much). Itdepends on who you are. I think diet and exercise has something to do about it too.
