WHY DO WE NEED TO RAISE THE AGE?

A significant minority of adolescents now show signs of addiction-like engagement. Globally,11% of young people demonstrate problematic social media use, characterised by compulsive checking, withdrawal symptoms, and continued use despite harm. Girls are particularly affected — in England, 20% of 11-year-old girls and 23% of 13-year-old girls meet criteria for problematic use. This pattern is associated with lower life satisfaction, irritability, and psychosomatic complaints, independent of perceived social support.

Sleep disruption is one of the most consistent harms linked to social media. Higher use is
directly associated with shorter sleep duration and difficulty falling asleep. Bedroom screen use is the strongest predictor of exposure to mature content and disrupted sleep.
Poor sleep then compounds risk: it affects brain regions responsible for emotional regulation and decision-making, increasing vulnerability to depression. In short, more social media
leads to less sleep — and less sleep increases mental health risk.

Early social media access predicts earlier substance use. Engagement at ages 11–12 is associated with increased likelihood of trying alcohol, nicotine and cannabis within the following 18 months. Each additional hour spent on social media increases the risk of early “alcohol sipping,” a behaviour strongly linked to later misuse. Social platforms have also been identified as facilitating access to drug markets, exposing young people to additional harms.

The association between addictive social media use and suicidal behaviour is particularly concerning. In a longitudinal study of over 4,000 adolescents, 31.3% showed rising addictive use over four years, and this group had double the risk of suicidal behaviour. Early smartphone ownership (before age 13) is associated with poorer emotional regulation, lower self-worth and increased suicidal thoughts in young adulthood. Age of first social media account explains around 40% of the link between smartphone access and later mental health difficulties.

Social media amplifies unrealistic appearance ideals and diet culture. A review covering 50 studies across 17 countries found consistent links between social media use, body dissatisfaction, disordered eating and poor mental health. Each additional hour online increases the odds of engaging in risky eating behaviours (odds ratios ranging from 1.05 to 1.55). Hospital admissions for eating disorders among girls aged 11–15 have risen by 515% in recent years. Notably, anorexia nervosa remains the psychiatric illness with the highest mortality rate.

Exposure to violence online is widespread. 56% of 13–17-year-olds report seeing fights involving young people, and 35% have seen children carrying or promoting weapons on social media. Alarmingly, only 6% actively searched for violent content — most encountered it through feeds or direct sharing. Teachers report that 59% attribute deteriorating behaviour in schools partly to social media use, suggesting that online exposure influences offline conduct.

Online harms disproportionately affect vulnerable groups. Children receiving Free School Meals are more likely to report exposure to online harms (74% vs 60% of non-FSM peers) and are more likely to say being online makes them sad. Children with SEND, those in care, and those experiencing poverty are at greater risk of exploitation, including criminal recruitment via social media. Research consistently shows that offline vulnerability extends into online life, magnifying existing inequalities.

Higher social media use is linked to increased rates of depression, anxiety, ADHD symptoms, obsessive-compulsive traits, disruptive behaviours and self-harm. Longitudinal research shows this relationship is not merely correlational — rising use predicts worsening symptoms over time. Adolescence is a critical period of identity formation, and constant social comparison, algorithmic reinforcement, and appearance- focused culture intensify self-criticism and dissatisfaction.

The evidence is clear: social media is not a harmless habit for early adolescents. Its impact on whole-child mental health is measurable, cumulative and growing.

The digital ecosystem in the UK has shifted from a communication utility to a high-risk environment characterised by exploitation, manipulation and abuse. Evidence indicates that social media platforms pose a systemic and unmanageable threat to the safety, developmental health, and social integration of children.

The risks are no longer anecdotal side effects of digital engagement but are endemic features of platforms that prioritise engagement metrics, data extraction and profit over children’s safety.

The result is a generation of children who are increasingly isolated in their physical lives while being hyper-exposed to risk in their digital lives.

Social media algorithms are designed to maximise engagement, not protect children. They track behaviour and progressively feed users more extreme or attention-grabbing content.

Young people rarely search for harmful material intentionally — instead, it is delivered to them. Research shows that users with eating disorders were exposed to +335% more dieting content and an alarming +4,343% more toxic eating disorder videos compared to controls. This automated amplification creates powerful “rabbit holes” that shape beliefs, identity and behaviour during critical stages of brain development.
