Excessive screen exposure hinders child development, while guided use can foster learning and growth.
According to the findings of a recent study, screen time shows a dual impact — educational use under supervision supports cognitive growth, while prolonged or unsupervised use harms children’s focus, sleep quality, and social wellbeing.
Children grow up in an increasingly digital world where screen-based technology is deeply integrated into daily life. While screens offer educational and recreational opportunities, concerns have emerged about their potential impact on various aspects of child development, including physical health, cognitive abilities, emotional regulation, and social skills.
Investigators systematically searched major scientific databases, including PubMed, Scopus, Web of Science, and PsycINFO, for studies published from 2014 to 2024 that investigated the effects of screen exposure on child and adolescent development. Only peer-reviewed articles in English that focused on participants aged 0 to 18 and addressed at least one aspect of physical, cognitive, emotional, or social development were considered. Each study was independently screened and critically evaluated by two reviewers following PRISMA standards to ensure methodological rigor and quality.
The review of 46 studies showed that screen time affects children’s cognitive, social, emotional, physical, and language development. The impact depended on the type of screen use, its duration, and parental involvement.
The authors highlight the importance of conducting long-term research to better comprehend how digital exposure shapes developmental trajectories. Until then, maintaining balanced screen use — combining learning opportunities with healthy boundaries — remains key to promoting children’s well-being in a digital world.
