A recent study from the University of Oxford has found that the majority of young people who encounter self-harm content online do so unintentionally, often due to algorithm-driven social media feeds. Researchers analyzed data from 32,102 students aged 11 to 18 who participated in the 2025 OxWell Student Survey in England. Approximately one-third of respondents reported seeing self-harm-related material on social media in the month prior to the survey.

Of those who encountered such content, nearly 72 percent said they had not actively sought it out. Instead, much of this exposure was the result of algorithms designed to keep users engaged by suggesting related posts, videos, or images within their feeds. About 66 percent reported that the content was recommended to them through these automated systems.

Lead author Dr. Holly Bear noted that self-harm content could include a range of posts, from potentially harmful material to supportive narratives such as personal recovery journeys shared by peers. However, the high prevalence of unintentional exposure raises concerns about the potential negative impact on vulnerable adolescents.

The findings, published in the journal Nature Mental Health, emphasize the need for a multifaceted approach to address the issue. Researchers recommend public health measures aimed at reducing passive exposure to harmful content via platform algorithms. Additionally, they stress the importance of tailored support for the smaller subset of young people who actively engage with self-harm material online. The study calls for coordinated efforts encompassing digital literacy education, changes in platform design, regulatory frameworks, and enforcement actions.

This research comes amid increasing international attention on social media’s impact on youth mental health. France recently became the first European country to approve legislation banning social media use for children under 15, effective from September, with a requirement to delete existing accounts by January. The United Kingdom is also moving toward similar restrictions, with a planned ban on certain social media platforms for children under 16 expected to take effect by spring, following announcements by Labour Party leader Keir Starmer.

Experts emphasize that addressing the algorithms governing content delivery is critical to mitigating unintended exposure to harmful material. Dr. Bear and her colleagues argue that platform policies and broader public health strategies must evolve to better protect adolescents navigating social media environments where self-harm content is prevalent.
