School Smartphone Ban Improves Sleep and Mood
2024-12-15
A three-week school smartphone ban experiment at the University of York showed significant improvements in students' sleep and mood. Students fell asleep 20 minutes faster on average, gained an hour of sleep nightly, and reported 17% less depression and 18% less anxiety. While cognitive improvements were modest, researchers suggest longer-term bans may yield greater benefits, informing policy decisions regarding smartphone use among young people.
