Researchers conducting a six-week trial with thousands of schoolchildren across the UK are placing curbs on their access to popular social media platforms, gathering data on how those restrictions affect the young participants' sleep, mental wellbeing, and day-to-day lives. Roughly 4,000 to 5,000 young people between the ages of 12 and 15 are taking part in the research, which is under way in Bradford, West Yorkshire.
Researchers at Bradford are set to investigate what happens when young people's access to platforms such as Instagram, TikTok and Snapchat is restricted. Those taking part will be subject to two platform-use constraints: a cap on how many hours per day they may spend on social media, and a ban on access during overnight hours.
Researchers will track how those adjustments affect participants' psychological wellbeing, nightly rest, and day-to-day functioning. The study's authors are looking to the data to determine whether cutting back on social media use translates into tangible shifts in how teenagers experience their daily lives.
Jointly coordinated between the Bradford Institute for Health Research and the University of Cambridge, the work places researchers at the intersection of social media habits and the psychological and emotional health of young people. Findings from the study are intended to shed light on whether placing limits on adolescents' social media activity yields measurable gains in their wellbeing, with the results also expected to feed into the broader policy conversation around age-based access rules for digital platforms.
Under plans set out by the government, children under 16 in the UK would lose access to social media platforms from spring 2027. New rules on age verification for social media platforms are set to take effect under a regulatory framework the government aims to finalise before the close of 2026.
Platform-specific services — among them Instagram, TikTok, Snapchat, Facebook, YouTube, and X — fall within the scope of the proposed age-based restrictions, while messaging applications such as WhatsApp and Signal sit outside the under-16 provisions as the government's plans currently stand. Overnight access to social media platforms would be blocked for 16- and 17-year-olds between midnight and 6 am under the plan, which also sets autoplay and personalised feeds to off by default for that age group.
A separate UK government pilot, which enrolled 309 families and focused on teenagers between the ages of 13 and 17, preceded the broader Bradford research effort. Three methods formed the backbone of that four-week trial: capping daily social media access at 15 minutes, blocking platform use through an overnight window running from 9 pm to 7 am, and stripping out certain social media apps entirely.
Both teenagers and their parents took part in structured interviews conducted at two points — once before the pilot programme began and again after it concluded — with the aim of gauging how the usage restrictions shaped participants' sleep patterns, general wellbeing, time spent on offline pursuits, and the quality of their social ties. A report on the topic was published by the Department for Science, Innovation and Technology in July 2026, with the department describing the research as aimed at building the evidence base around how young people navigate restrictions placed on their social media use.
Findings from the Bradford study are anticipated to contribute to an expanding field of inquiry into whether limiting young people's access to social media platforms can benefit their overall wellbeing, at a time when policymakers are weighing stricter controls over how children engage with those platforms online.
