In a\u00a0landmark decision<\/a>, a Los Angeles jury has found that social media company Meta and video streaming service YouTube harmed a young user with addictive design features that led to mental health distress, including\u00a0body dysmorphia, depression and suicidal thoughts<\/a>.<\/p>\n Commentators have referred to this as\u00a0social media\u2019s \u201cBig Tobacco\u201d moment<\/a>\u00a0and\u00a0further lawsuits<\/a>\u00a0are pending. The verdict has\u00a0escalated calls for more regulation<\/a>\u00a0of social media platforms across jurisdictions.<\/p>\n Countries like\u00a0Australia<\/a>,\u00a0France<\/a>\u00a0and\u00a0Spain<\/a>\u00a0have already introduced age restrictions for social media use. Canada still lacks\u00a0online harms legislation<\/a>.<\/p>\n As\u00a0parents campaign<\/a>\u00a0and\u00a0policymakers consider how to address online harms<\/a>, one crucial question is often overlooked: Why are teenagers so uniquely vulnerable to these platforms in the first place?<\/p>\n Imagine Sara, who at 14 was found unconscious on her bedroom floor after an attempt to take her own life. By every measure, she was thriving: strong in school, supported by family, living in a vibrant community. But behind her bedroom door, she was struggling with something no one could see. She spent hours scrolling, posting and chasing likes until the validation stopped coming.<\/p>\n A quiet sense of not being good enough slowly took root. Despite 150 online followers, she had no one she felt she could truly talk to. She became convinced she was completely alone.<\/p>\n Sara is a composite drawn from clinical and research experience, but her story is common. Like many teenagers, Sara turned to social media to connect, express herself and find a sense of belonging. At first, it felt good. Each\u00a0quick hit of dopamine<\/a>\u00a0drew her back until the habit became hard to control.<\/p>\n Neuroscience shows that heavy social media use can overstimulate the teen brain\u2019s still-developing reward pathways in ways similar to\u00a0addictive behaviours like gambling<\/a>.<\/p>\n This immature system also makes teenagers\u00a0more sensitive to social feedback<\/a>\u00a0and\u00a0less able to cope with rejection<\/a>. This leaves them vulnerable to highs and lows of online interaction, including the rapid, repeated negative comments that can intensify emotional stress.<\/p>\n This imbalance<\/a>\u00a0means that the fast emotional traffic often outruns the signals from the control centre, creating traffic jams in judgment and rational thinking and making it harder for teens to pause, reflect and assess consequences.<\/p>\n Social comparison deepens this strain further. As Sara scrolled through images of seemingly perfect lives, she felt increasingly inadequate.\u00a0Envy<\/a>, insecurity and\u00a0fear of missing out<\/a>\u00a0chipped away at her confidence. At the same time, social media encouraged constant self-monitoring, as she tracked her likes, comments and appearance online.<\/p>\n Research links this kind of\u00a0inward focus<\/a>\u00a0to\u00a0higher levels of anxiety<\/a>, especially in teens already under pressure.<\/p>\n Puberty\u00a0adds another layer<\/a>. During this stage, the brain becomes more sensitive to social and emotional cues. For girls, these changes often occur earlier and more intensely, helping explain why adolescent girls are disproportionately affected by\u00a0social media-related anxiety and depression<\/a>.<\/p>\nDopamine hits to immature pathways<\/strong><\/h4>\n
