“Heavier use of social media and video games does not in itself worsen teenagers’ mental health, despite widespread concerns,” according to a new study that challenges long-held assumptions about the impact of digital habits on young people.
Research led by the University of Manchester found no evidence that higher levels of social media use or more frequent gaming increased symptoms of anxiety or depression over a one-year period. The findings, published in the Journal of Public Health, suggest that links between screen time and declining mental health may be overstated.
The study tracked around 25,000 students aged 11 to 14 across three school years, examining their online activity alongside reported symptoms such as low mood and anxiety. Researchers also compared different types of social media engagement, including active use such as messaging and posting, and passive use such as scrolling. The overall results remained consistent: patterns of use alone did not predict later mental health problems.
“We know families are worried, but our results do not support the idea that simply spending time on social media or gaming leads to mental health problems – the story is far more complex than that,” said lead author Qiqi Cheng.
The researchers said public debate often focuses heavily on potential harms, while overlooking benefits such as maintaining friendships, sharing experiences and exploring identity through online platforms.
The team also reviewed earlier studies that claimed direct links between digital activity and emotional distress. They argued that many of those findings fail to consider whether poor mental health may influence online behaviour rather than result from it.
“Mental health struggles: cause or consequence?” remains a key question, the researchers said. Adolescents who already feel anxious or depressed may turn to social media for reassurance or connection, or use gaming as a distraction from difficult emotions.
“Our findings tell us that young people’s choices around social media and gaming may be shaped by how they’re feeling, but not necessarily the other way around,” said co-author Neil Humphrey.
He added that attention should shift away from blaming technology itself and towards understanding what young people are doing online, who they are interacting with, and how supported they feel in their offline lives.
The researchers acknowledged limitations in the study. The data relied on self-reported behaviour and emotions, and the 12-month gap between measurements may not capture short-term changes. Teenagers’ moods and online habits can vary sharply from day to day.
The findings come as concern grows about rising mental health problems among young people. The World Health Organization’s European office estimates that more than 30 million children and adolescents aged 0 to 19 in the region live with a mental health condition. Mental health and substance use disorders are now the leading cause of disease burden among people aged 0 to 29.
Among adolescents, more than one in five are affected, a proportion that has risen by about one third over the past 15 years.
The Manchester researchers said their work does not dismiss the need for safeguards online, but calls for a more balanced understanding of how digital life fits into teenagers’ emotional development.
