Abstract
Fatigue levels among nurses began to increase significantly 4 hours into their 12-hour shifts, peaking at 7:30 pm.
- Fatigue accumulated across consecutive shifts, indicating a potential need for ongoing fatigue monitoring.
- Subjective sleep quality was reported to be better the night before the second shift compared to the first.
- Nurses who experienced poor sleep prior to a shift displayed higher levels of fatigue during that shift.
- Monitoring sleep characteristics may be important for managing fatigue effectively.
