| Abstract: | This article explores the influence of social media on the self-esteem and mental health of adolescents. With the pervasive use of platforms like Instagram, TikTok, and Snapchat, young individuals are increasingly exposed to idealized images and curated lifestyles that can distort their self-perception. The study analyses both positive and negative effects, considering factors such as social comparison, cyberbullying, and the role of social support networks. Findings indicate that while social media can foster connectivity and a sense of belonging, it also poses significant risks for mental health, including anxiety, depression, and lowered self-esteem. Recommendations for mitigating adverse impacts include promoting digital literacy and encouraging balanced media consumption. |
