We evaluated the impact of night reading on daytime sleepiness, quality of sleep and performance of student. Pharmacy students (N = 253, 71.5% response rate) completed a sleep and study lifestyle questionnaire, the Pittsburgh sleep quality index and the Epworth sleepiness scale questionnaires, and their grade indices (were obtained. The results showed that the prevalence of night reading was 76.7% and there was a significant (P < 0.05) association between night reading and sleep quality, and also between sleep quality and academic performance. Thus, habitual night reading may affect academic performance, possibly due to the reduced sleep and poor sleep quality of habitual night readers. © 2008 The Authors Journal compilation © 2008 Japanese Society of Sleep Research.
