Explanation:
Teens typically need up to 10 hours of sleep each night to function at their best during the day. Problem is, many adolescents don't get the healthy sleep they need. Getting teens on a regular sleep schedule can improve their health, as well as their performance at school and at home, but it will require a creative approach. If you have a teen, you have seen firsthand that children's sleep needs change over time. According to Kathy Gromer, MD, a sleep medicine physician at the Minnesota Sleep Institute in Edina, infants need roughly 16 hours of sleep each day. By age 4, children begin sleeping mostly at night, but they still need 10 to 12 hours of sleep. "Teens need 9 to 10 hours, although there is some natural variability," says Dr. Gromer.
While teens' daily sleep requirements do decline somewhat, they also naturally begin going to bed later. "It isn't just bone-headedness, it's biology," says Gromer. But this normal tendency can spell trouble if high school hours start earlier than what teens are used to. And when teens' sleep needs and a shifting sleep schedule are combined with a packed activity schedule, it can cut into the amount of healthy sleep they’re getting. Factor in their tendency to wake up later in the morning on weekends, and it can add up to frustration for parents trying to get their teens on a healthy sleep schedule.
