The habit of scrolling through social media is more detrimental than you might realize, particularly for adolescents.

      A decade-long study highlights the potential mental health risks associated with excessive social media use by teenagers.

      A recent study from Australia strengthens the case against social media, particularly regarding its impact on teenagers. Conducted by the Murdoch Children’s Research Institute, the research indicates that adolescents who spend over two hours daily on social media are more likely to report depressive symptoms and reduced wellbeing a year later compared to those who engage with social platforms for under an hour each day.

      While the study does not establish a direct cause-and-effect relationship between social media use and mental health issues, the connection is significant due to the longitudinal nature of the research, rather than relying solely on short-term data.

      Critical period identified in early adolescence

      The research tracked nearly 1,200 children in Melbourne, from ages nine to 19, as part of the Child to Adult Transition Study. Researchers gathered yearly data on social media usage and mental health outcomes, including depression, anxiety, and self-harm. The most pronounced association was seen in girls aged 12 to 13, a crucial time for potential intervention. Dr. Nandi Vijayakumar of MCRI and Deakin University noted that early adolescence appears to be a time when increased social media use correlates with a heightened risk of mental health issues a year later.

      Ages 12 and 13 often see the convergence of phones, social apps, peer pressure, and other influences. Thus, even a slight increase in risk can be significant when millions of young people are engaging with the same platforms daily.

      Why simply removing apps isn’t a solution

      The researchers emphasized the complexity of the issue, noting that social media can provide valuable support for some teenagers, fostering a sense of belonging, self-expression, and friendship networks—essential for those who struggle to find such connections offline. However, high usage can also lead to greater exposure to cyberbullying, harmful content, and comparisons that negatively impact sleep and contribute to the pressure to remain constantly connected.

      Professor Susan Sawyer from MCRI stated that while the results do not indicate that social media is inherently harmful, they do support the need for age-specific limits, improved digital literacy, and clearer guidance for parents.

      These findings come at a time when governments are deliberating on age restrictions and regulations for young social media users. Australia has already implemented pioneering age restrictions for social media, and MCRI along with Deakin University is simultaneously researching the impact of these changes on teenagers’ smartphone usage and mental health.
