Early bedtimes during preschool years reduces risk of ADHD.

Children who do not get early, adequate sleep before the age of 4 are more likely to develop ADHD (attention deficit/hyperactivity disorder). A study of 6868 preschool children from the Early Childhood Longitudinal Study-Birth Cohort has found that early, regular bedtimes is a strong predictor of normal development.  Lack of regular sleep in this age group leads to inattention, hyperactivity, impulsivity, and ultimately lower academic performance.
