The rise of social media has transformed modern communication, creating connectivity and fostering new platforms for self-expression. However, this shift has raised significant concerns about its effects on mental health. This article critically examines the relationship between social media use and mental health. While social media can provide valuable social support and facilitate the sharing of personal achievements, evidence suggests it may also contribute to heightened anxiety, depression, and body dissatisfaction, especially among adolescents and young adults. The article analyzes how social media algorithms, the pressure to present an idealized self-image, and constant comparison with others create an environment where self-esteem and mental well-being are often compromised. Furthermore, the long-term implications of social media use, including its impact on attention spans, social isolation, and self-worth, are discussed. Ultimately, this article emphasizes the importance of understanding and managing social media’s influence on mental health to create healthier digital environments.
