Long weekend sleep is linked to stronger academic performance in male but not female pharmacy students

Abstract

Introduction Poor sleep hygiene portends loss of physical and mental stamina. Therefore, maintaining a regular sleep/wake schedule on both weekdays and weekends is highly recommended. However, this advice runs contrary to the habits of university students, who may only experience recovery sleep if they sleep late on weekends. Pharmacy students at Duquesne University sit for frequent examinations, typically commencing at 7:30 AM, and they complain about fatigue. Here, we tested the central hypothesis that longer sleep durations on weekdays and weekends are linked to stronger academic performance in Pharmacy students.Methods Students in their first professional year were administered three surveys to collect data on sleep habits and factors that might influence sleep, such as roommates, long commute times, and sleep interruptions. GPAs were collected from the Dean’s office, with permission from the students.Results Longer weekend—but not weekday—sleep durations were significantly correlated with higher cumulative GPAs in men and not in women. Women achieved slightly higher cumulative GPAs than men. Students who fell asleep within 15 minutes of going to bed had higher professional-phase GPAs than those who fell asleep after an hour or more.Conclusion Our observations cannot establish causal links, but, given the body of prior evidence on the salutary properties of sleep, men in this cohort may reap benefit from recovery sleep on weekends. Rather than recommending that students force themselves awake early on weekends in an attempt to maintain a consistent sleep routine, the real-life habits of students should be given consideration.View Full Text
