Introduction: Sleep deprivation due to night work among nursing professionals can compromise their health. Fatigue complaints are often mentioned, as well as difficulty to recover from work. Aim: To evaluate if napping during night work (duration, latency, allocation and quality) is associated with need for recovery from work, and fatigue perception among nursing professionals. Methods: A cross-sectional study was conducted among nursing professionals in a public hospital of the city of São Paulo, Brazil. At this hospital, napping was allowed during night work. Female nurses and nursing assistants who worked night shifts (19:00h 7:00h) and did not report sleep complaints (N = 49) filled in a questionnaire. The questionnaire included sociodemographic data, aspects of professional and domestic work and health (need for recovery from work - the total score ranged from 0 to 100 - and fatigue perception - the total score ranged from 30 to 150). As a second step, they used an actigraph for 10 consecutive days that allow us to evaluate their wake-sleep cycle. Activity diaries were also filled out during this period of time. Results: The majority of participants (87%) nap during all working nights. The mean duration of napping at work was 136 minutes (sd= 39.8 min). Those who nap in the first half of the night (00:00h-03:00h) showed the longest napping duration, compared to those who nap between 03:00h-06:00h. The perception of sleep quality during night work (napping) was lower compared to night sleep at home during off-days. The sleep latency, either at work, or at home did not show significant differences. The sleep efficiency at work was similar of night sleep efficiency at home, but was higher 29 when compared with sleep efficiency of day sleep at home. The longest duration of napping was associated with long hours of domestic work and higher domestic overload. The mean need for recovery from work was 43.6 points and perception of fatigue was 63.5 points. The younger workers, those who performed short hours of domestic work and registered nurses reported a higher perception of fatigue. There were no associations between sleep during night work (duration, latency, allocation and quality) and need for recovery from work and fatigue perception. However, among participants who worked six or more nights every 15 days, the higher the perception of fatigue and need for recovery from work, the higher the efficiency of sleep during night work. Conclusions: In spite of different napping durations were not associated with fatigue and need for recovery, napping showed positive effects to participants in relation to sleep efficiency and social aspects of their lives.
