Senior British doctors are warning that social media is becoming as dangerous to children’s health as smoking, as pressure grows on the UK government to introduce tougher restrictions for users under 16.
The warning comes from the Academy of Medical Royal Colleges, which represents 23 medical colleges and faculties across the UK and Ireland. In a submission to the government’s online safety consultation, the organization said doctors are increasingly treating children suffering physical and mental harm linked to excessive social media and smartphone use.
According to the report, more than half of the surveyed doctors said they encounter at least one case every week involving health issues connected to online content, digital platforms, or screen overexposure. Clinicians reported cases involving anxiety, depression, sleep problems, self-harm, exposure to violence, radicalization, and injuries caused by children imitating dangerous online challenges.
The Academy said the issue has become a “unifying force” for the medical profession comparable to public health campaigns involving smoking and seatbelt safety. Doctors warned that children are being exposed to “hateful, addictive and grossly distressing content” through recommendation algorithms and engagement-focused platform design.
The growing concerns come as the UK government considers new online safety measures targeting minors. Proposals currently under discussion include social media bans for under-16s, app curfews, restrictions on addictive platform features, and mandatory screen time controls.
Australia became the first country to introduce a nationwide social media ban for children under 16 in 2025, and several European governments are now considering similar measures. Britain has already implemented online safety laws requiring platforms to reduce children’s exposure to illegal and harmful content, but ministers have signaled plans to go further.
Former UK Health Secretary Wes Streeting also backed stronger restrictions, comparing major technology companies to the tobacco industry. He accused social media platforms of designing addictive systems that prioritize engagement over child safety.
Prime Minister Keir Starmer met with families this week who say social media platforms contributed to the deaths or harm of their children. Following the meeting, officials indicated the government could announce new policy measures within weeks.
The UK’s “Growing Up in the Online World” consultation closed this week after receiving tens of thousands of responses from parents, educators, healthcare professionals, and technology companies. Ministers are expected to publish formal proposals later this year.
