Infants sleep about 16 hours a day, while teenagers need 9 hours on average. For most adults, 7 to 8 hours a night appears to be the best amount of sleep, although some people may need as few as 5 hours or as many as 10 hours of sleep each day.
Given this much, we now know why we sleep. The average adult sleeps 7 to 8.6 hours a day. Children sleep more than adults; they spent about 10 hours a day sleeping. Newborns, however, may sleep for nearly two-thirds of their day. There is an age-related difference in average time spent sleeping. As a person ages, they require less sleep. The elderly only spent around 6.5 hours a day sleeping.
