The document discusses the relationship between social media use and depression. It provides evidence from multiple studies that prolonged social media use is linked to depressive symptoms in teenagers and young adults. Specifically, the constant comparison to idealized versions of others' lives presented on social media can increase feelings of exclusion and anxiety. Additionally, social media encourages shallow interactions and narcissistic behavior over meaningful face-to-face connections, which has been tied to greater isolation and loneliness. While social media allows for global connectivity, unmanaged overuse may contribute to mental health issues like depression by disrupting real-world social skills and relationships.
