The Digital Mirror: Understanding the Impact of Social Media on Youth Mental Health

The proliferation of social media platforms has fundamentally restructured how young people communicate, construct identity, and engage with the world around them. This paper examines the relationship between social media usage and youth mental health through a doctrinal and analytical framework, drawing upon international and national studies, government reports including India’s Economic Survey 2026, data from the World Health Organization, and the World Happiness Report 2026. The analysis addresses key psychological mechanisms — social comparison processes, dopaminergic feedback loops, fear of missing out (FoMO), and the displacement of in-person interaction — that mediate the relationship between platform use and psychological well-being, and concludes that mental health impact is determined not by exposure alone but by the quality and intentionality of engagement.
