People need eight hours of sleep each night, some may need a little more and some a little less, but four hours is definitely not enough. Our bodies need rest to be at optimum health, just as much as they need nutritious food and regular exercise.
Most adults need 6-8 hours of sleep, but children or growing people may need 7-9 or more, depending on age.
It is commonly reported that people need 8 hours of sleep per night, but recent studies point otherwise. These studies showed that adults who got 6 to 7 hours of sleep per night lived longer than those who got less than 6 or greater than 7 hours of sleep. As long as your sleep is undisturbed, there is no reason why a person would need more than 7 hours per night. Children, teenagers, and elderly people may need more than this though.
Some people need more sleep than others for several reasons. Some people are busier and need more sleep and some may need more sleep due to genetic reasons.

Around 8 hours or more but you can sleep less if you wan to or need to so about 8 hours.
The average is 8 hours, some people require 10 hours and there is approximately 35% that only need six hours (I'm one of those people.) It depends if you have REM sleep (deep sleep) and if you do then even six hours is enough for many people. If you are a lighter sleeper then 8 - 10 hours is a must. Children from 1-19 need at least 10 hours of sleep each day.
While sleep requirements vary slightly from person to person, most healthy adults need seven to nine hours of sleep per night to function at their best. Children and teens need even more. And despite the notion that our sleep needs decrease with age, most older people still need at least seven hours of sleep.
