Overuse of social media has contributed to a crisis in mental health, says a warning from the World Health Organization. Since it induces the brain’s release of dopamine, made to entertain based on the rewards mechanism, it pushes one toward more addiction behavior. There are neural effects and psychological and somatic expressions of overuse, including increased anxiety levels, depression, and cognitive decline, and impacts on cardiovascular health, sleep, and vision. The article further urges immediate action through education, policy regulation, and personal interventions to prevent these risks and protect future generations.
