Digital technologies dominate students' academic, social, and leisure activities, although excessive use of digital media can harm psychological well-being. In this cross-sectional study, we examined the predictive role of digital engagement patterns on well-being, burnout, and sleep quality among university students. A sample of 120 students (60 males and 60 females) from Islamabad/Rawalpindi completed the (WEMWBS), (DBOS), and (PSQI). Correlation analyses showed that increased digital engagement was linked to higher burnout, lower mental well-being, and poorer sleep quality. Emotional exhaustion emerged as the most significant predictor of decreased well-being and disrupted sleep. These findings highlight the mental health risks of heavy online use and underscore the need for interventions promoting healthy technology habits and sleep maintenance. The study enhances understanding of how digital behaviors influence students' emotional, cognitive, and physical performance.
