Sleep is very important. Did you know that sleep is more important than food? A person who does not sleep dies faster than a person who does not eat.

Teenagers need 9 to 10 hours of sleep. An adult needs an average of 7 to 8 hours a night. There are dome people who need only 3 hours of sleep. Others need 1 hours of sleep. After the age of 50, the average sleep time goes down to 6.5 hours a night. We need less sleep as we get older.
