In our times where life flows fast, working life is not exempt from destabilizing factors, which play an important role in the quality of sleep and the quality of life of any human being. Objective: To determine the factors related to the quality of sleep in workers in the health area. Materials and methods: A systematic review of the data from 2008 to 2018 was carried out. Articles in Spanish, English and Portuguese were reviewed from PUDMED databases, MEDLINE, SCIELO, using the terms of search quality of sleep, factors related, workers in the area of health and sleep disorders. The variables included were sociodemographic, occupational and those related to sleep quality. Results: Sleep quality disorders were related to sociodemographic and psychosocial factors. The prevalence of poor sleep quality in the general population was 39%, in men 34% and in women 44%. 58% of nurses working night shifts reported problems falling asleep and these were associated with age, sex, area where they worked, years of service and night shift frequency (p <0.05). Nursing students had a prevalence of depression, anxiety and stress of 35.8%, 37.3% and 41.1% respectively. Men tend to have lower sleep quality problems than women (p = 0.0218). Significant differences were found between the body mass index (p = 0.0014) and exercise (p = 0.0020) with respect to the quality of the diet. Body mass index and sleep quality were also significantly associated (p = 0.0032). Conclusion: There are detonating factors that deteriorate this quality, some are exogenous such as the performance of night shifts, family conflicts and marital status that affect the quality of sleep and trigger anxiety and stress disorders. Among the endogenous factors we can mention the gastrointestinal alterations and the imbalance in the diet.
