A Cross-Sectional Study on Sleep Duration, Circadian Disruption, and Academic Performance Among College Students

Abstract Sleep is a critical physiological process influencing cognitive performance, emotional stability, and academic success. However, irregular sleep patterns and circadian disruption are increasingly prevalent among college students due to academic pressures and lifestyle habits. The present cross-sectional study aimed to evaluate sleep duration, circadian disruption, and their association with academic performance among college students.
Data were collected using a structured questionnaire administered through a Google form. A total of 209 students participated in the study. Variables included sleep duration, sleep timing, circadian behaviors, lifestyle factors, and academic performance. Descriptive statistics, Chi-square tests, and multiple linear regression analysis were applied.
The results indicated that 39.2% of students slept 5–6 hours on weekdays, while 15.8% slept less than 5 hours. Weekend sleep duration improved significantly (p < 0.05). Circadian disruption was evident, with 31.1% reporting irregular sleep schedules. Significant associations were observed between sleep duration and academic performance (χ² = 12.64, p < 0.05), and between daytime sleepiness and concentration difficulties (χ² = 18.27, p < 0.01). Regression analysis showed that sleep duration positively predicted academic performance (β = 0.32), whereas circadian disruption (β = −0.21) and daytime sleepiness (β = −0.35) negatively affected outcomes.
The findings suggest that inadequate sleep and circadian misalignment significantly impair academic performance. Promoting sleep hygiene and consistent sleep patterns is essential for improving student well-being and academic success.
