This concept paper explores the complex relationship between social media usage and the mental health of young adults. The paper introduces the notion of social media and its significance in the lives of young adult, emphasizing the importance of studying its effects on their mental health and psychological well-being. Social media platforms have become an integral part of daily activities in the lives of young people. It has also become an invasive element in the lives of youth, shaping their social interactions, self-perception, and access to lots of information. Even though these platforms offer opportunities for social connection, creative expression, and educational engagement, they also present significant mental health challenges, including anxiety, depression, and low self-esteem, which are often driven by social comparison, cyberbullying, and the pressure to maintain an idealized online image. The paper investigates key areas of concern, including the rise of anxiety, depression, and low self-esteem linked to social comparison, cyberbullying, and the relentless pursuit of online validation. It also examines the addictive nature of social media, its impact on sleep, and the destruction of face-to-face social skills. By analysing existing literature and identifying research gaps, this paper aims to provide a comprehensive framework for understanding the two-edged nature of social media's influence on mental health. It advocates for the development of digital literacy programs, mental health support systems, and balanced usage strategies to help young people navigate the challenges posed by social media while maximizing its potential benefits.
