The American Academy of Sleep Medicine recommends eight to ten hours of nightly sleep for teenagers. Most get less than seven. There's robust evidence linking nighttime media use to poor sleep. For many teens, nighttime scrolling fills the hours meant for rest. Our work and others' show that more than 70 percent of adolescents say they check their phones after going to bed, and many wake up in the night to respond to notifications.
For the study, researchers at the University of Oregon and the State University of New York Upstate Medical University analyzed data from more than a thousand 16 to 24-year-olds in which participants reported their sleep/waking hours, including weekend catch-up sleep. While one might imagine that teens who spring out of bed early each morning - regardless of the day of the week- are more mentally sound, the opposite may be true. Interestingly, the study found that teens who slept in on weekends were significantly less likely to report symptoms of depression. The group had a 41% lower risk of depression when compared with the group who kept a more regimented sleep schedule on weekends.
