6 to 8 hours: Most people will perform best and have the best health with 6 to 8 hours of sleep. Your body will tell you what you need. Eventhough some people do well with less than 6 hours others may need more than 8. The quality of sleep is also important and if deep sleep is not achieved, 8 hours may not be enough.
