Abstract

The exponential rise of social media in the 21st century has fundamentally transformed how humans communicate, build relationships, and construct identities. While digital platforms such as TikTok, Instagram, Snapchat, Twitter (X), and Facebook have created unprecedented opportunities for global connectivity, self-expression, and civic engagement, they also raise pressing concerns about their impact on psychological well-being. The consequences of excessive social media use are particularly evident among adolescents and young adults, who form the largest demographic of users. This paper critically investigates the behavioral and psychological outcomes of social media use, drawing on both global scholarship and Nigerian case studies.

The research highlights negative effects, including addiction, sleep disruption, academic decline, anxiety, depression, loneliness, and reduced self-esteem. Nigerian-specific contexts—such as sextortion networks like the “BM Boys,” cyberbullying of public figures like Chef Dammy, and exam malpractice through social media and AI tools—demonstrate how these global risks manifest locally. Financial strain, online scams, and the spread of hate speech further exacerbate the problem.

At the same time, the paper acknowledges positive dimensions, such as opportunities for identity exploration, peer support, and access to educational resources. Employing a qualitative desk research methodology, the study synthesizes findings from international peer-reviewed journals, reports, and Nigerian media sources. The paper concludes that while social media can empower youth, the risks of unregulated use outweigh the benefits. Recommendations include introducing digital literacy education, strengthening parental and institutional guidance, implementing government regulations, and expanding access to mental health services.
