    In a new analysis of 1 million U.S. teens, my co-authors and I looked at how teens were spending their free time and which activities correlated with happiness, and which didn’t.

    (…) every activity that didn’t involve a screen was linked to more happiness, and every activity that involved a screen was linked to less happiness. The differences were considerable: Teens who spent more than five hours a day online were twice as likely to be unhappy as those who spent less than an hour a day.

    Of course, it might be that unhappy people seek out screen activities. However, a growing number of studies show that most of the causation goes from screen use to unhappiness, not the other way around.
