The mean sleepiness level assessed by the KS score was lower, 3.3 (SD±1.6), when the nap was taken during the first span (00:01 - 03:00h) of the night shift, compared with 6.6 (SD±1.0) when there was no nap. The mean sleepiness level assessed by the KS score was also lower, 3.6 (SD±0.9), when the nap was taken during the second span (03:01 - 06:00h) of the night shift, compared with 7.0 (SD±1.1) when there was no nap. Thus, napping either during the first or second part of the night shift reduces sleepiness of 12-hour, night-shift nursing personnel. Moreover, the mean duration of the first sleep episode after night work was longer in those who did not nap than in those who did.<br>CONCLUSIONS: The results of this study show that napping during the 12-hour, night-shift results in less sleepiness at work and less need for recovery sleep after work.<p> 1 Chronobiology Circadian Rhythm Occupational Health Nurses Workplace document-rn33986 2023-09-30T20:36:00.593-05:00 37114 2 21617
