SCREEN TIME EXPOSURE IN CHILDREN AND ITS IMPACT ON SLEEP QUALITY, VISION, AND BODY MASS INDEX

Abstract

This article synthesizes current evidence and guidance on how screen time influences sleep through circadian disruption and sleep displacement, influences vision through prolonged near work and reduced outdoor time, and influences body mass index through increased sedentary behavior, appetite stimulation, food marketing exposure, and sleep-mediated metabolic effects. Practical, family-centered strategies are proposed for clinicians and caregivers, emphasizing screen-free sleep routines, device placement rules, outdoor activity protection, and regular vision and growth monitoring.
