This study utilized objective video monitoring and wearable sensors to move beyond unreliable self-reporting when investigating how adolescent technology use affects rest. The researchers discovered that while general screen time in the two hours before bed had little impact on sleep, device use while physically in bed significantly reduced total sleep time. The findings highlight that interactive activities, such as gaming or multitasking, are far more disruptive to sleep health than passive consumption. Consequently, the authors suggest that traditional advice to avoid all screens before bed is outdated, arguing instead that interventions should focus specifically on restricting device engagement after getting into bed.
