The Surgeon General called social media's safety unproven

The short answer

In 2023 the United States Surgeon General published an advisory that does not say social media is proven to harm children, and does not say it is proven safe either. Its actual claim is narrower and, in its own way, more useful: there is not yet enough evidence to say social media is sufficiently safe for children and adolescents, and five different groups, policymakers, technology companies, researchers, parents and young people, each have something they can do about that gap.

What the evidence says

The advisory states its central finding directly: 'At this time, we do not yet have enough evidence to determine if social media is sufficiently safe for children and adolescents.' It was built, by its own account, through 'a substantial review of the available evidence... with priority given to, but not limited to, meta-analyses and systematic literature reviews', rather than an exhaustive literature review. It cites specific studies on both sides: a longitudinal cohort of 6,595 American adolescents aged twelve to fifteen found that those spending more than three hours a day on social media faced roughly double the risk of poor mental health outcomes after adjusting for baseline mental health, while a separate randomised trial found that limiting social media use to thirty minutes a day for three weeks measurably improved depression scores, especially among those who started with higher baseline symptoms. The advisory also names concrete risks, including exposure to harmful content and design features built to maximise engagement, such as autoplay and infinite scroll.

For context

The advisory is unusually candid about what remains unknown, devoting a full section to 'critical questions' it says are still unanswered, including which specific content and design features cause the most harm, and for whom. It also identifies a structural barrier to closing that gap: technology companies hold much of the relevant data, and independent researchers largely cannot access it, which the advisory calls out explicitly as limiting what any single document can conclude. Its policy recommendations draw an analogy to how the United States already regulates toys, vehicles and medicines, a 'safety-first' principle requiring safety to be demonstrated before wide use, which is a stronger stance than most professional-body guidance in this batch, even though its own evidence base is, by its own account, still developing.

A practical next step

Among its many recommendations for families, two are concrete enough to act on directly: build a family media plan together, and keep phones, tablets and computers out of use for at least an hour before bedtime and overnight.

• Which of the advisory's five groups, policymakers, companies, researchers, parents or young people, do you have any real influence over?
• Does your household already have a rule for the hour before bedtime, and is it actually followed?
• What would change in your own view if the missing data the advisory describes eventually became available?

An advisory built around admitted uncertainty is not indecisive; it is an accurate description of where the evidence currently stands, paired with a case for acting on incomplete information rather than waiting for certainty that may be years away.
