Strict smartphone rules may cause teenage groans, but they also bring extra sleep and better grades.
A new University of Geneva study shows that 13- to 15-year-olds who hand over their phones in the evening snooze an average of 40 minutes longer. That’s nearly an extra night’s rest per week.
Lead researcher Virginie Sterpenich notes that teens need about nine hours of sleep, but usually only get seven to eight.
Parents, it seems, hold the power button - no phone in the bedroom equals more sleep and sharper school performance.
Other limits, like screen-time caps, hardly moved the needle. Bottom line: bedtime really does beat screen time.
