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.
How many hours of sleep does a person need?
I am only sleeping 2-4 hours a night. I can’t go to sleep until sometimes 4 or 5 am and am awake by 8am, this has been happening for the last 5 nights, I figure I’ve had under 18 hours of sleep since last Thursday, one night not sleeping at all.. What am I to do?
How much sleep should a person actually get per night?
I ask because I’ve been told that a person should try to complete full sleep cycles of roughly 3 hours each at night, and that waking up in the middle of a sleep cycle actually makes you feel more tired. So, would a 3 hour nap be better than 1.5? Should we abandon the 8 hours of sleep standard?
