THE “GOLDILOCKS” LEVEL OF TEEN SCREEN USE

It pays to get the time spent on a device just right.

It’s a familiar lament: Teenagers are spending all their time on digital devices, and it’s wreaking havoc on their physical and mental health. But a study published in January in Psychological Science suggests a moderate level of use is not necessarily harmful—and may even be beneficial. The effect on well-being varies depending on the type of medium or device: TV and movies, video games, computers and smartphones, as well as the day of the week (weekday versus weekend). The optimal amount of exposure peaks at around one to two hours daily during the week and longer on weekends.

A graph plots several curves corresponding to teens’ daily digital-screen engagement in hours for weekdays and weekends. The vertical axis shows the mental wellbeing between 40 and 50. The data are as follows. You can read full description from the link below.

Limiting your teen’s screen time is fine, but consider the benefits before you pull the plug entirely.
