US Surgeon General's office issues a public-health warning on children's screen time
The US Surgeon General's office, part of the Department of Health and Human Services, has issued an extensive warning document detailing the public-health risks of prolonged screen time for children and adolescents. According to STAT News, the document draws on more than 300 peer-reviewed studies published between 2010 and 2025, and offers concrete recommendations for families, educators, technology companies and policy-makers. This is the office's most comprehensive official statement on screen time in recent years.
In the warning document, daily screen time (excluding educational use) is recommended at less than 2 hours for children aged 9-12 and less than 3 hours for adolescents aged 13-17. For social-media use, the document endorses the existing US federal guideline (COPPA) advising that children under 13 should not open accounts; for adolescents over 13, accounts under parental consent and supervision are recommended.
The report particularly emphasises data on screen time's effect on mental health. Referencing a 2024 meta-analysis from Yale University, it notes that adolescents using social media more than 4 hours daily show a 47% higher rate of depressive symptoms. Citing a Mayo Clinic study, the report documents that adolescents aged 13-17 with daily social-media use of 3 hours show an average sleep-duration shortening of 90 minutes.
Sleep is one of the most strongly emphasised areas in the report. The document states that keeping a mobile phone in the bedroom at night delays sleep onset by an average of 38 minutes and measurably reduces REM sleep quality. Families are advised to keep phones away from children's bedrooms overnight and to maintain at least one hour of screen-free time before bed.
In the section addressed to technology companies, the Surgeon General's office made three concrete demands. First, real-time transparent labelling on advertising designed for children and restriction of advertising data collection to those with parental consent. Second, annual disclosure to an independent auditing body of the types of content algorithms preferentially deliver to children and adolescent users. Third, platform design features such as 'infinite scroll' and 'auto-play' should be off by default on child accounts.
The family-facing section includes concrete daily-routine suggestions. Keep 'screen-time' tablets out of bedrooms; choose 'device-free activities' (camping, learning a musical instrument, cooking) for family weekends; limit screen use to a single time window in the home (for example between 17:00 and 19:00). The Surgeon General's office references research findings showing these suggestions have positive effects on children's social lives and school performance.
The regulatory debate in the United States is also accelerating. The 'Kids Online Safety Act 2.0' bill, co-sponsored in Congress by Republican and Democrat senators, would oblige technology platforms to report child-user data annually to a federal regulator. The Surgeon General's new warning document may reinforce public sentiment in favour of supporting that bill.
The response from technology companies has so far been mixed. Meta Platforms' vice-president of corporate policy Jennifer Newstead said in a press statement, 'we are seriously evaluating parts of the Surgeon General's recommendations, particularly in collaboration on improving parental control tools.' TikTok, in its official response, said its 120-minute daily screen-time notice is automatically delivered to younger age categories and will remain that technical default.
Some children's-health organisations questioned whether the Surgeon General's document was strong enough. The American Academy of Pediatrics (AAP) said in its statement that 'the recommendations point in the right direction, but guidance documents without enforcement mechanisms are not sufficient on their own.' AAP continues to push for federal-level legislation on children's digital safety. Common Sense Media said in a parallel statement that the technology industry's history of self-regulation has failed.
The decision will also affect clinical decision-making. The Surgeon General's public-health warnings are being integrated into the routine pediatrician examination standard in the United States so that screen-time questioning becomes standard during visits; major children's health systems such as Mayo Clinic, Cleveland Clinic and Stanford Children's Hospital are reported to be adding screen-time evaluation to standard intake forms in 2025. Medical professionals are expected to convert this warning into a clinical-conversation framework. The Surgeon General's announcement this week is regarded as an important turning point in children's health policy; in family-communications terms, the official position of the most widely followed health agency in the United States is now clear.
