Abstract
Sleep is a fundamental biological need essential for health and well-being. Adolescents are especially vulnerable to the effects of sleep deprivation due to rapid developmental changes and increasing academic demands. This study aims to examine sleep deprivation problems among adolescents in a selected Chinese high school in Johor, Malaysia. The study employs a quantitative approach using the Pittsburgh Sleep Quality Index (PSQI). data were collected from 254 students aged 13 to 17. The findings revealed that 65.7% of the students were affected by sleep deprivation as measured by a Pittsburgh Sleep Quality Index (PSQI) global score >5. Key contributing factors include academic workload, screen time, irregular sleep patterns, and psychological stress. The study underscores the importance of school-based and family-level interventions to promote healthy sleep behaviours among adolescents.
