Most adults need between six and nine hours of sleep every night. By working out what time you need to wake up, you can set a regular bedtime schedule. Winding down is a critical stage in preparing for bed. A warm bath (not hot) will help your body reach a temperature that's ideal for rest.
REM sleep occurs at intervals of one to two hours, and is variable in length. REM sleep is characterized by irregular breathing and heart rate, and involuntary muscle jerks.

Children, particularly teenagers, often need nine or ten hours for optimal functioning.
