Recent events have reignited debate over whether social media is the root cause of increasing youth self‐harm and suicide. Social media is a fertile ground for disseminating harmful content, including graphic imagery and messages depicting gendered violence and religious intolerance. This proliferation of harmful content makes social media an unwelcoming space, especially for women, minority groups, and young people, who are more likely to be targeted by such content, strengthening the narrative that social media is at the crux of a youth mental health crisis.

However, the parallel rise in social media use and youth mental health problems does not imply a causal relationship. Increased social media use may be a correlate, exacerbating factor, or a consequence of rising trends in youth self‐harm, which may have entirely separate causes. Despite its potential negative impacts, social media is also a source of information and support for young people experiencing mental health problems. Restricting young people's access to social media could impede pathways for help‐seeking. This complexity highlights the need for a considered approach.

Recommendations  

• Understand why some individuals are more susceptible to social media harms.
• Assess alternative explanations for youth self-harm trends.
• Mitigate artificial intelligence (AI)-related risks.
• Evaluate interventions that restrict social media and ensure they are evidence-based.
