AN ANALYSIS OF DUAL IMPACT OF SOCIAL MEDIA ON MENTAL HEALTH AND SOCIAL LIFE OF YOUTH

Abstract

Social-media platforms like Facebook, Instagram, TikTok, and YouTube are central to the
everyday life of teenagers, helping them to be connected, to explore their identity, and to
have support from their peers. On the other hand, these platforms also increase the chances of
mental health problems, low self-esteem, sleep disorders, and unhealthy habits. The origins of
these problems include mechanisms such as upward social comparison, circadian disruption
due to screen exposure in the evening, emotional hyperarousal caused by receiving
notifications and algorithmic amplification of risky content. The evidence, in general, shows
consistent moderate associations across various domains: depression and anxiety (r≈0.27)
that are connected to cyberbullying and FOMO; body image dissatisfaction (r≈0.21, which is
more in females) that is associated with the consumption of idealized visual content; sleep
problems wherein 30–45 minutes of delayed sleep onset, reduction of deep sleep, and
daytime sleepiness are observed (r≈0.19); and heightened behavioral risks (e.g., NSSI,
antisocial behavior, gambling, polysubstance, and sexual risk) in particular among multiplatform heavy users (>3 hours/day). There are still methodological issues, as most of the
studies are cross-sectional, depend on self-report, are skewed towards WEIRD populations,
and usually consider “social media” as one entity although there are differences between
platforms. However, longitudinal and experimental evidence, which is converging, shows
that there is bidirectional reinforcement between social media use and adverse outcomes.
Considering that the damages are most severe in vulnerable subgroups (early adolescents,
females, LGBTQ+, low-SES youth), there is a need for multi-level responses, such as digital
literacy programs, family media plans, platform-level reforms (age-gating, safer algorithms),
and regulatory measures modelled on other public health interventions.
