The rapid proliferation of social media platforms over the past decade has transformed the way young adults communicate, socialize, and consume information. While social media offers numerous benefits such as enhanced connectivity, access to information, and opportunities for self-expression, its impact on mental health has become a growing concern. This paper explores the complex relationship between social media use and mental health outcomes among young adults, highlighting both the positive influences and the potential risks, including anxiety, depression, and social isolation. By reviewing recent empirical studies and theoretical frameworks, this study examines the factors that mediate and moderate these effects, such as usage patterns, content exposure, and individual vulnerability. Furthermore, it discusses intervention strategies and policy recommendations aimed at mitigating negative consequences while promoting healthy social media engagement. The paper concludes by emphasizing the need for a balanced approach that leverages social media�s opportunities while addressing its challenges to foster psychological well-being in the digital age
