How Social Media Use Affects Student Performance
A team from the University of Milan-Bicocca has discovered that middle schoolers who create social media accounts at age 11–12 are often noticeably behind their classmates by the time they reach 15–16. Published in Nature Human Behaviour, the study drew on data from 5,227 Italian students, comparing when they first opened TikTok or Instagram accounts with their final grades in mathematics, Italian, and English. As concerns about teen screen time grow worldwide, these findings provide a concrete measure of potential academic cost.
The results show that children who began using social media at age 11 end up roughly six months behind their peers on exit exams. Students who signed up at 11–12 performed significantly worse in math and Italian than those who waited until age 14–15—a gap equivalent to half a year of schooling. Interestingly, early access had no measurable impact on English scores, which researchers attribute to the massive volume of English-language content available on the internet.
What This Could Mean and What Might Change
Because the study is observational, other factors such as family income or home circumstances may also influence academic results. Even so, similar worries have led the United Kingdom to consider stricter rules for young people's use of popular platforms. Among the proposed measures are:
- a complete ban on Instagram, TikTok, YouTube, Snapchat, Facebook, and X for anyone under 16;
- a nighttime curfew for teens aged 16–17, blocking online access between midnight and 6 a.m.;
- requiring companies to turn off autoplay videos and endless news feeds by default.
The study highlights how crucial it is to guide young people's social media habits, since registering early may harm academic progress. It also strengthens the call for parents and schools to encourage balanced digital routines. These proposed UK restrictions may be the first step in a broader effort to shield teenagers from the downsides of online environments.
