3.4.4 Social media, emotional wellbeing and mental health disorders

Over 90% of adolescents in the UK and US own a smartphone, with approximately 70% of teenagers using social media platforms daily (Ofcom, 2022; Pew Research Center, 2022). There is a growing body of evidence linking high social media usage to increased rates of anxiety, depression, self-harm and suicidal ideation among young people (Twenge, 2023). Adolescents spending more than three hours per day on social media have double the risk of experiencing poor mental health outcomes compared to peers with minimal use (Twenge et al., 2019). Generation Z, sometimes referred to as the iGen, have been particularly affected, reporting rising dissatisfaction with life and higher rates of depressive symptoms. This runs alongside a marked increase in teenage suicide rates over the past decade (Twenge, 2023).

Addressing the adverse impact of social media on youth mental health requires a multi-faceted approach. Schools and policymakers are encouraged to develop robust digital literacy curricula that educate students about healthy online behaviours, critical consumption of digital content and the risks associated with excessive use (Livingstone & Smith, 2014). Promoting open dialogue about mental health, training staff to recognise digital distress signals, and implementing early intervention pathways are vital steps (Reavley & Jorm, 2010).

Parental involvement is also crucial; setting clear boundaries for device usage and encouraging offline activities can mitigate negative outcomes (Odgers & Jensen, 2020). Furthermore, integrating social-emotional learning programmes into the curriculum helps students build resilience and coping skills, thereby reducing the impact of online stressors (Durlak et al., 2011). Collaboration between educators, mental health professionals, and technology providers is essential for creating safer digital environments and effective support systems (Patel, 2022).

Several interventions have demonstrated success in reducing the harmful effects of social media on young people. Notably, phone-free school initiatives—where mobile devices are restricted during the school day—have led to improved academic engagement, reduced cyberbullying and enhanced student wellbeing (Beland & Murphy, 2016). Schools in France and the UK that have implemented device bans report fewer classroom disruptions and increased face-to-face interaction among students (BBC, 2019).

In parallel, structured digital detox programmes and peer-led support groups have shown promise in helping students moderate their online habits and seek help when needed (Smith et al., 2021).
