The circadian typology is a behavioral dimension associated with preferences of daily habits. Thus, this study aimed to evaluate the quality of sleep and excessive sleepiness of undergraduates in psychology. Fifty-five students aged between 17 and 34 years participated in this quasi-experimental study. The Pittsburgh Sleep Quality Index, the Morningness-Eveningness Questionnaire, the Karolinska Sleepiness Scale, and the Brief Social Rhythm Scale were used as instruments. After assessing the PSQI, all participants answered the instruments for a period of 14 consecutive days. MANOVA showed significant difference for daily sleepiness during the working days [λλ=.81; F(4.47)=451.53; p<.05], specifically for business hours of 21h [F(2;5)=3.03; p<.05]. It is concluded that students have poor sleep quality and generally try to compensate for the lack of nights of sleep during the week on weekends.
