Social media has become an inseparable component of modern life, particularly among adolescents and young adults. Excessive and uncontrolled use of social networking platforms has led to a growing phenomenon known as social media addiction. This behavioral addiction is increasingly associated with adverse psychological, physiological, and cognitive outcomes. The present paper reviews and analyzes the relationship between social media addiction, sleep disturbances, and cognitive impairment. The study explores how prolonged exposure to social media platforms negatively influences sleep quality, sleep duration, memory, attention, academic performance, and executive functioning. Data from previous studies demonstrate that addictive social media use significantly contributes to delayed sleep onset, insomnia, daytime fatigue, impaired concentration, reduced working memory, and decreased academic productivity. The study also highlights the neuropsychological mechanisms underlying these effects, including dopamine-mediated reward pathways, blue-light exposure, emotional arousal, and disrupted circadian rhythms. The findings suggest that social media addiction is an emerging public health concern requiring behavioral interventions, digital literacy education, and awareness programs.
