The pervasive influence of social media on modern society has sparked significant discourse regarding its impact on mental health and well-being. This research paper delves into the complex interplay between social media usage and psychological outcomes, aiming to provide a nuanced understanding of the implications for individuals, communities, and society at large. Drawing upon a multidisciplinary approach encompassing psychology, sociology, and communication studies, this paper examines the various ways in which social media platforms shape perceptions, behaviors, and mental health outcomes. It explores both the positive and negative aspects of social media use, acknowledging its potential for fostering social connections, disseminating information, and facilitating self-expression, while also recognizing its role in exacerbating feelings of loneliness, comparison, and anxiety.
