people need between 8 to 11 hours of sleep depending on their age and health. For example; a teenager needs a minimum of 9 hours of sleep a night while an adult only needs between 7 to 9. The more sleep a person gets, the better it is for their well being.
Most adults need between 7-9 hours of sleep a night. Some may need less, and too much sleep can just make you feel more tired.The National Sleep Foundation has a useful chart on their website for all age groups.http://www.sleepfoundation.org/article/how-sleep-works/how-much-sleep-do-we-really-need
