Sleep Quality and Psychological Well-Being Among Postgraduate Students
Abstract: Sleep is a fundamental biological process that supports cognitive functioning, emotional regulation, and overall mental health. Postgraduate students represent a population that is particularly vulnerable to disturbed sleep because of intensive academic workloads, research pressures, career uncertainty, and lifestyle irregularities. This article examines the relationship between sleep quality and psychological well-being among postgraduate students by reviewing recent empirical literature and outlining a conceptual and methodological framework for further research. Evidence consistently indicates that poor sleep quality is associated with lower psychological well-being, higher levels of depressive symptoms, anxiety, and stress, whereas adequate and restorative sleep is linked to better emotional stability, life satisfaction, and academic functioning. The article discusses contributing factors such as academic stress, interpersonal sensitivity, psychological capital, and lifestyle habits, and proposes a correlational research design using standardised tools such as the Pittsburgh Sleep Quality Index (PSQI) and Ryff's Scales of Psychological Well-Being. The discussion highlights implications for student counselling services, sleep hygiene interventions, and institutional mental health policy, and concludes with recommendations for future longitudinal and intervention-based research.
