Social media addiction has emerged as a significant global public health concern, affecting over 210 million individuals who meet clinical criteria for behavioural addiction. With 5.24 billion social media users worldwide representing 62% of the global population, the scale and consequences of problematic use are vast and poorly understood by the general public. This review examines the multi-dimensional harms of social media addiction across six domains: interpersonal relationships, family structure, behavioural patterns, physical health, mental health, and societal consequences, with specific attention to the Indian context. A narrative review of published literature was conducted, drawing on peer-reviewed research from the Pew Research Centre, Harvard T.H. Chan School of Public Health, Stanford University, JAMA Pediatrics, the U.S. Surgeon General's Office, the National Mental Health Survey of India, and a 2025 Tamil Nadu cohort study, among others. Findings are synthesised thematically across the identified domains. Evidence across domains consistently demonstrates that social media addiction causes measurable harm: phubbing and social comparison damage intimate relationships and contribute to rising divorce rates (1 in 3 now cite social media); parental distraction disrupts child attachment and development; behavioural changes include shortened attention spans, impulsivity, and the displacement of authentic experience by performative living. Physically, sleep deprivation, sedentary behaviour, and musculoskeletal injury are well documented. Mentally, youth anxiety has risen 134% and depression 106% between 2010 and 2018, paralleling smartphone adoption. Social media platforms are deliberately engineered to exploit neurological reward mechanisms, producing dependency with wide-ranging consequences for individuals, families, and societies. Urgent action is required at regulatory, institutional, and cultural levels. In India, this includes mandatory age verification, phone-free schools, and expanded mental health resources addressing digital addiction.
