US teens spend an average of more than seven hours per day on screen media for entertainment, and tweens spend nearly five hours, a new report finds – and that doesn’t include time spent using screens for school and homework.

Among teens, the amount of time dedicated to several individual screen activities inched up by 42 minutes per day since 2015, the report said. Nearly 62% spend more than four hours a day on screen media and 29% use screens more than eight hours a day, according to a report by Common Sense Media, a nonprofit organization that helps kids, parents and schools navigate media.
