Abstract
A 1-hour afternoon nap before the first night shift may equalize neurobehavioural performance with the second night shift.
- Neurobehavioural impairment is typically worse on the first night shift compared to subsequent shifts.
- Twelve male volunteers with a mean age of 22.9 years participated in the study.
- Participants underwent a laboratory simulation of two 12-hour night shifts.
- Neurobehavioural performance and subjective sleepiness were measured during both shifts.
- No significant differences in performance or sleepiness were observed between the first and second night shifts.
