Objective: The aim of this study was to evaluate the sleep quality of medical students to identify the main factors that affect sleep patterns. Methods: According to the methodology, 154 students participated in the research, attending from the first to the sixth year of the course. The Pittsburg Sleep Quality Index questionnaire and the Epworth sleepiness scale were applied. Descriptive statistics techniques were applied and demonstrated in the form of tables and graphs. The comparison of variables was carried out using statistical tests. Results: The results showed that most students do not sleep very well. It was observed that 68.83% of a total of 106 students are bad sleepers. Conclusion: It is concluded that medical students sleep a low number of hours by period, which could interfere in impairment of attention, learning and memory formation, interfering in academic performance. On the other hand, they showed greater daytime sleepiness compared to the general population.
