Sleep assessment during shift work in Korean firefighters: a cross-sectional study

ConclusionsWe found that the sleep quality in night shift of shift work group was poorer than control group. As to the type of shift work, sleep quality was good in 6-day shift and poor in 21-day shift. So fast rotating shift like 6-day shift may be recommended to improve the sleep quality of the firefighters.
