Healthy Amounts of Sleep for Children

Adequate sleep is recognized as a pillar of physical and mental health. The amount of sleep children get affects not only how much energy they have but also their abilities to learn and stay healthy.

There are four components to healthy sleep for children:
  • quality
  • quantity/amount of sleep for the child’s age, including daytime
    and nighttime
  • positioning (bumpers, wedges, co-sleeping, flat surface)
  • environment (home life factors, presence of stress, parental marital discord, establishment of routines, room temperature/noise levels/darkness)
Healthy sleep is necessary for:
  • Consolidation of cognitive performance, required for executive functioning, abstract reasoning, goal-directed behavior, and creative processing
  • Operation of overnight brain processes thought to influence cognitive, physical, and emotional regulation during the day
Unhealthy sleep is associated with:
  • an increased risk for overweight and obesity
  • mood disorders
  • overtiredness, poor response time, costly behaviors, driving accidents, and alcohol/cigarette/marijuana use
  • aggression, depression, anxiety, inattention, overactivity, internalizing, problem behaviors, and psychosomatic symptoms
  • poor school performance, learning capacity, and neurobehavioral function
