Effects of Less Sleep on Children: What Scientific Studies Prove

Based on five reviewed studies, we suggest that school age children should sleep at least 10 hours (better 11.5 hours) per day. Otherwise, it increases the odds of obesity in childhood and adulthood and lead to poor IQ performance; preschoolers should sleep at least 10 hours per night. Otherwise, there is a risk of external behavioral problems (hyperactivity-impulses) and poor intellectual performance.
