The association between short sleep duration and obesity is stronger in children and adolescents than in adults, and may weaken with age.

Pay close attention to sleep duration, especially if you are a parent or young adult. Children and teens are particularly vulnerable to weight gain from short sleep. While the effect may diminish in older age, maintaining 7-8 hours of sleep is still a key component of metabolic health.
