More than half of teens are losing sleep to phone use.

May 26 2026

More than half of teens are losing sleep to phone use. A new UCSF study that tracked teens’ phone patterns shows more than half used their phones between midnight and 4 a.m. Overall, the survey found that teens scrolled on their phones late on school nights, averaging 50 minutes between 12-6 a.m. The majority of their late-night screentime was devoted to social media apps like YouTube, Instagram, or TikTok, or gaming platforms like Roblox. Researchers say that teens losing sleep during those critical hours are more susceptible to depression, anxiety, and impaired cognitive development. The consensus is that the best solution is to get rid of screens from the bedroom, especially while teens should be asleep. But given that two thirds of teens sleep with their phones or other electronics in their rooms, that will be a tough habit to break—if teens don’t find a way around anyway. (Washington Post)
