This study aimed to investigate the relationship between sleepiness and physiological changes and vital signs in night shift workers in rehabilitation staff. Materials and Methods: This study was a cross-sectional study performed on night shift personnel of Rafideh Hospital in Tehran City, Iran, in 2018. A questionnaire, including demographic information and the Stanford sleepiness scale, was used for data collection. The results were analyzed using repeated measures analysis in SPSS software v. 21. Results: The Mean±SD age of the participants was 38.23±5.96 years, comprising 33 men (64.7%) and 18 women (35.3%). Most personnel were married (72.5%) and non-smoker (82.4%). The amount of sleepiness increased significantly with increasing working time. Demographic characteristics had no significant association with sleepiness. However, there was a significant negative association between sleepiness and heart rate, and oral temperature. Blood pressure showed a decreasing trend with increasing working time until midnight. Also, an increase in blood pressure was recorded at 2 AM. Conclusion: The findings of this study showed that sleepiness might have a significant association with vital signs in night work personnel. Hence, proper planning of shift work schedules and compatibility with physiological conditions might result in better working conditions for medical staff. }, URL = {http://hdq.uswr.ac.ir/article-1-391-en.html}, eprint = {http://hdq.uswr.ac.ir/article-1-391-en.pdf}, journal = {Health in Emergencies and Disasters Quarterly}, doi = {10.32598/hdq.7.3.435.1}, year = {2022} }
