THE IMPACT OF SMARTPHONE ADDICTION ON SLEEP QUALITY AMONG UNIVERSITY STUDENTS

Smartphone addiction has emerged as a significant public health concern among university students, with growing evidence linking excessive smartphone use to deteriorating sleep quality. This comprehensive study examines the multifaceted relationship between smartphone addiction and sleep quality among university students, exploring the underlying psychological mechanisms including depression, anxiety, stress, self-regulation, and bedtime procrastination. Drawing upon recent empirical research from 2020 to 2025, this work synthesizes findings from large-scale cross-sectional studies, longitudinal investigations, and mediation analyses conducted across diverse university populations. The prevalence of smartphone addiction among university students ranges from 23% to 52.8%, with students exhibiting smartphone addiction demonstrating significantly higher risks of poor sleep quality, shorter sleep duration, and increased insomnia symptoms. Key mediating factors include psychological distress (depression, anxiety, and stress), poor self-regulation, and bedtime procrastination. This research aims to provide a comprehensive understanding of these relationships and inform evidence-based intervention strategies for promoting healthy smartphone use and improving sleep quality among university populations.
