Sleep is when important processing, restoration and strengthening occur throughout your immune, nervous, skeletal and muscular systems, according to the National Sleep Foundation.
Good sleep benefits your whole body including your heart and brain with effects such as improved mood, memory and reasoning.

- 14-17 hours for newborns (0-3 months)
- 12-15 hours for infants (4-11 months)
- 11-14 hours for 1- and 2-year-olds
- 10-13 hours for 3- to 5-year-olds
- 9-11 hours for 6- to 13-year-olds
- 8-10 hours for 14- to 17-year-olds
