Sleep and PA

This study investigates how sleep quality and physical activity relate to academic performance among male university students in Saudi Arabia. Using validated Arabic versions of the PSQI and IPAQ-SF, along with measured BMI and self-reported GPA, we examined whether better sleep and higher physical activity levels independently predict higher grades. The findings highlight that poor sleep is common and, together with lower physical activity, is associated with poorer academic performance, underscoring the need for campus-based health promotion strategies.
