Abstract
Objective: To investigate the relationship between screen time and cognitive impact in adolescents, analyzing relevant studies. Methods: This is an integrative review regarding the relationship between screen time and cognitive repercussions in adolescents conducted in the period between 2021 and 2023, using the PubMed database, the Health Sciences (DeCS) descriptors “Time of screen”, “Cognition” and “adolescents”. Results: 6 articles were selected for analysis. The studies reviewed present evidence of a significant association between screen time and cognitive impairment in adolescents, associations consistent with mental health problems, disturbed sleep, and risk of cognitive disorders. Blue light from devices negatively impacts sleep by suppressing melatonin production and disrupting the circadian rhythm, leading to difficulty falling asleep and reduced sleep quality. Final considerations: The relationship between screen time in adolescence and mental and cognitive health challenges is multifaceted, involving socioeconomic, behavioral and technological factors. Personalized interventions and holistic approaches are essential to mitigate negative effects and promote a healthy balance in digital device use.
