This study examines the impact of binge-watching behaviour on sleep disruption among teenagers amid the growing use of digital streaming platforms and personal devices. A descriptive research design was used, with data collected from 128 respondents through a structured questionnaire and analysed using frequency distribution, ANOVA, t-test, and correlation. Findings show that most teenagers frequently binge-watch for extended periods, often late at night, leading to difficulty stopping and delayed bedtimes. The results indicate significant negative effects on sleep, including reduced duration, irregular patterns, difficulty falling asleep, and increased daytime fatigue, which also affects academic concentration. Correlation analysis revealed a strong positive relationship (r = 0.753, p < 0.001) between binge-watching and sleep disruption. The study highlights the need for awareness and healthier media consumption habits to improve sleep quality and overall well-being.
