Sleep quality is an important factor involved in students' learning process. Using different methods, actual studies suggest that complaints about sleep problems are common in young medical students. The aim of this study was to evaluate if is any relation between factors like medium and lifestyle among students of the University of Medicine and Pharmacy "Grigore T Popa" from Iaşi. The study group included 30 students (2 of them were excluded) who performed a polisomnography, self reported Epworth questionnaire and two weeks sleep diary. Coffee, energy drinks, green and black tea and alcohol intake were recorded. In our evaluation it was used sleep disturbance index (SDI), for sleep quality description. In those two weeks, the mean sleep hours was 7.8 (95% CI 7.6-8), greater in female than in male. The results suggest a significant correlation between psychical excitants and sleep fragmentation. More, excessive daytime somnolence declared is not in concordance with sleep quality observed in sleep recorded with polysomnography. It looks to be in correlation with bad sleep habits and psychical excitants intake.
