Social media profoundly influences the mental health of young adults, both positively and negatively. On the positive side, it provides connection, support communities, and platforms for self-expression. However, overuse and unhealthy patterns of engagement often lead to anxiety, depression, low self-esteem, and sleep disruption. Young adults are particularly vulnerable to social comparison, where they measure their lives against curated highlights of others, leading to feelings of inadequacy or failure. Cyberbullying, exposure to unrealistic beauty standards, and fear of missing out (FOMO) further exacerbate mental health struggles. Excessive screen time disrupts real-life relationships, physical activity, and rest, all of which are crucial for psychological well-being. Studies have shown that heavy social media use correlates with higher rates of loneliness and depressive symptoms. While social media is not inherently harmful, mindful usage is key. Setting time limits, curating positive content, and engaging in offline activities can create balance. Parents and educators can also play a role by promoting digital literacy.
