The group found that adequate sleep duration for age on a regular basis leads to improved attention, behavior, learning, memory, emotional regulation, quality of life, and mental and physical health. Not getting enough sleep each night is associated with an increase in injuries, hypertension, obesity and depression, especially for teens who may experience increased risk of self-harm or suicidal thoughts.
In addition to these recommendations, the AAP suggests that all screens be turned off 30 minutes before bedtime and that TV, computers and other screens not be allowed in children's bedrooms. For infants and young children, establishing a bedtime routine is important to ensuring children get adequate sleep each night.
