A comprehensive review shows that social media can both support and harm young people’s mental health, depending on how, what, and when they use platforms. Active engagement and context matter more than screen time alone, prompting calls for digital education and offline connections.
A new review suggests social media is neither simply good nor bad for adolescents and young adults, but that its effects depend heavily on how it is used, what people see, and the circumstances in which they use it. Published in Humanities and Social Sciences Communications, the paper argues that the same platforms that can support friendship, self-expression and access to help can also fuel anxiety, low self-esteem, loneliness and disturbed sleep.
The authors examined 33 peer-reviewed studies drawn from PubMed, Scopus and Google Scholar, covering people under 40. That wider evidence base fits with other recent reviews, including an umbrella review on adolescent mental health that found the research remains inconsistent, with some studies pointing to only weak links and others suggesting more substantial harms. A separate systematic review also concluded that the field still lacks clear answers on causation.
One of the clearest themes in the new review is that active, relational use tends to be more beneficial than passive scrolling. Posting about personal experiences, receiving encouragement and staying connected across distance can ease stress and strengthen social ties. Social media can also help people find mental health information and, in some cases, connect them with suicide-prevention support and peer communities.
But the paper also details clear risks. Exposure to idealised beauty standards, cyberbullying and self-harm content has been associated with body dissatisfaction, depressive symptoms, suicidal thoughts and other forms of distress. The authors say the pattern of use matters more than raw screen time alone, and note that problematic or compulsive use has been linked with sleep loss, loneliness, substance misuse and strained relationships.
The review also places social media in a wider developmental and cultural context. Adolescents are already more vulnerable because of changes in behaviour, cognition and neurobiology, according to related research in npj Mental Health Research. Cultural attitudes towards individuality and body image may also shape how harmful comparison becomes, which is why the authors say simple screen-time limits are not enough on their own. They call instead for digital literacy, content moderation, balanced online habits and more offline connection, while urging longer-term studies to better separate cause from effect.
