USE OF TECHNOLOGY IN ADOLESCENTS' MENTAL HEALTH POST-COVID-19 PANDEMIC AND SCHOOL LEARNING: A SYSTEMATIC LITERATURE REVIEW

Abstract

Introduction: The intensive use of digital devices has become a structuring part of adolescents' lives, especially in the post-COVID-19 pandemic period, altering routines, modes of interaction, and learning processes. Scientific evidence indicates that overexposure to technology can lead to cognitive and emotional harm, including reduced attention, irritability, low self-esteem, and anxious and depressive symptoms. Objective: To analyze, through a systematic literature review, the relationship between screen time, digital technologies, mental health, and psychosocial development of adolescents between 2020 and 2025. Methodology: Systematic review based on scientific articles, national reports, and indexed documents that discuss the impact of digital media use on adolescents in the post-pandemic period. Results: Between 90% and 93% of adolescents use the internet daily, indicating a consolidated pattern of hyperconnectivity. Prolonged use of technology has been associated with a decline in attention and memory, worsening school performance, impaired sleep, increased sedentary behavior, intensified social comparison, and weakened family and school relationships. Conclusion: Excessive exposure to digital media negatively influences the mental health and psychosocial development of adolescents. Family and school mediation has demonstrated an essential role in promoting the healthy use of technology and in preventing the risks associated with hyperconnectivity.
