Multiple outlets report that UK Prime Minister Keir Starmer plans to introduce an overnight curfew on social media use for teenagers as part of measures aimed at reducing “addictive scrolling.” Under the proposal, platforms would be expected to apply default settings that restrict access for older teenagers—specifically those aged 16 and 17—during late-night hours. The restriction is described as operating from midnight until 6:00 a.m. In practice, the policy would rely on platforms’ default account settings to prevent access rather than placing the burden entirely on individual users. The move is framed as part of wider efforts to address concerns about how social media can affect young people’s wellbeing, including their sleep and overall usage patterns. At this stage, details on implementation, enforcement, and whether exceptions would apply are not included in the provided excerpts. The reporting indicates the government is seeking to limit use during the hours when most teenagers would normally be asleep.
