Screen time is GOOD for teen brains: Why 257 minutes is the 'sweet spot' before computers damage mental health and behavior

Hours of screen time can be good for teenagers' brains, according to new research from the University of Oxford. The study insists many parents may be too concerned about computers harming their children. In fact, they calculated the'sweet spot' at which point young people get the most out of online activity: 257 minutes. According to their calculations, four hours and 17 minutes is the Goldilocks number, providing enough time to develop social connections and skills. It is only after that point that devices could begin to cripple teenage brains.
