Daytime Sleepiness

The use of technology before bed and relying on caffeine in the morning are affecting teens’ ability to stay alert and function during the day.

In a study in the journal, Pediatrics, researchers asked Philadelphia middle and high school students from 12-to-18-years-old about their sleep behavior, technology use, and caffeine intake. Researchers found that one-third of the students reported falling asleep in school. Caffeine consumption among this group was 76 percent higher.

Teens usually need about nine hours of sleep in order to function. In order for teens to get optimal sleep, they should avoid technology at least an hour before bed and limit their caffeine consumption.
