Should children under 16 be banned from social media in your country?
Researchers reported that social media is the number-one reason children are not getting recommended sleep. Australia became the first country to ban social media use for children under 16 in December 2025, and other countries have followed.
Why it matters
Growing concern about social media's effects on developing brains has prompted measures to restrict children's use of these platforms. The findings link sleep loss to brain development processes that are still underway in childhood.
Synaptic pruning eliminates around 40% of the synapses children had at the start of the process, a stage during which poor sleep is linked to impaired myelin formation. Brain scans showed a small but significant decrease in cerebellum volume among children with higher social media use, though the study does not establish how much of this reflects social media itself.

The details
Researchers say social media use is linked to shorter sleep and to attention patterns that may drive dopamine-driven addiction and constant need for stimulation. Findings from the Adolescent Behavior Cognitive Development Study associated screen time and shorter sleep with weaker white-matter organization and depressive symptoms in early adolescents. Preliminary findings on these effects were published in the journal Nature.

Youth Culture Shift
Australia's December 2025 ban on social media for users under 16 is the first national-level restriction of its kind, and other countries have since followed its lead. The new sleep and brain research supplies scientific grounds for such measures at a time when governments are reassessing youth access to these platforms.
Parents and caregivers may face decisions about whether to limit children's social media access in light of the sleep and brain findings. The research points to sleep as a concrete area where daily screen habits can be adjusted.
The takeaway
Protecting children's sleep may be one of the most practical steps families can take as researchers continue studying how social media shapes developing brains. Limiting screens before bed is a straightforward habit that parents can start now.
