New video explains the science behind sleepy teens

A new video developed by the American Academy of Sleep Medicine offers tips to help sleep-deprived teenagers get healthy sleep on a regular basis. Released during Student Sleep Health Week, the video “Why Are Teens So Sleepy?” highlights the challenges teenagers face to get sufficient sleep, recommends later school start times, and provides advice on how teens can develop positive sleep habits.

“The obligations of school, work, family and friends make it hard for teenagers to get sufficient sleep to perform their best,” said AASM President Dr. Raman Malhotra. “While it might seem like teens sleep a lot, most are sleep deprived and trying to catch up on the weekends.”

According to the Centers for Disease Control and Prevention, 78% of high school students don’t get enough sleep on an average school night. The AASM recommends that teenagers between 13 and 18 years old should obtain eight to 10 hours of sleep per night. One obstacle to achieving sufficient sleep, explained in the video, is that teenagers’ body clocks are naturally programmed to trigger sleepiness later at night and wakefulness later in the morning. That makes it more difficult for teens to get up for an early school day, which is why the AASM supports school start times of no earlier than 8:30 a.m. for middle and high schools.

“Adjusting school start times to better align with teens’ circadian rhythms is a positive step toward improving student achievement, health and safety,” said Malhotra. “Later school start times are associated with longer total sleep time, reduced daytime sleepiness, increased classroom engagement, and reduced tardiness and absences.”
