Objective: analyze the relationship between sleep quality, excessive daytime sleepiness, and health symptoms among the nursing team working in a hospital. Method: cross-sectional research, carried out with the nursing team of a public hospital in Brazil, between September 2017 and April 2018. A sociodemographic questionnaire, health symptoms, Sleepiness Scale, and the Pittsburgh Sleep Quality Index were used. Data are presented as absolute and relative frequencies, means, standard deviations, bivariate analysis, and binary logistic regression. Results: a total of 308 workers participated in the study, and poor sleep quality and absence of daytime sleepiness predominated among them. There was an association between sleepiness, children (p=0.006), and work accidents (p=0.044). Factors associated with poor sleep quality and drowsiness, appetite disorders, feeling of poor digestion, flatulence, weight gain, irritability, headache, feeling of low self-esteem, and mood lability. Conclusion: appetite disorder was the main factor for poor sleep quality for the nursing team working in a hospital in Brazil. This suggests that it is important to consider sleep quality when examining a worker´s health.
