Facts of Life

Children need at least nine hours of sleep each night for their health, safety and best performance in school and other activities, according to the National Center on Sleep Disorders Research (of the National Institutes of Health). Inadequate sleep can lead to attention difficulties, easy frustration and difficulty controlling emotions. Sleep “is just as important as healthy eating and exercise for children's development,” says Dr. Claude Lenfant, director of the National Heart, Lung and Blood Institute. Drawing by Tim Rauch
