How Sleep-Deprived Are Teenagers?

While teenagers need 9.25 hours of sleep to be optimally alert, multiple studies have shown that the vast majority today are living with borderline to severe sleep deprivation.

  • According to a 2010 large-scale study published in The Journal of Adolescent Health, a scant 8 percent of U.S. high school students get the recommended amount of sleep.
  • Some 23 percent get six hours of sleep on an average school night.
  • 10 percent get only five hours.
