      5 out of 6 U.S. middle and high schools start the school day before 8:30 AM

      The American Academy of Pediatrics has recommended that middle and high schools should aim to start no earlier than 8:30 AM to enable students to get adequate sleep.

      Teens need at least 8 hours of sleep per night.

      Younger students need at least 9 hours.

      2 out of 3 U.S. high school students sleep less than 8 hours on school nights
