Sleep, tiredness, and alertness during work hours in Korean nurses with rotating shifts
AI simplified
Abstract
Nurses experienced shorter sleep hours and lower sleep efficiency before night shifts compared to other shifts.
- Fatigue levels were highest before day shifts.
- Participants with alertness scores below 70 showed a significant decline in alertness, associated with sleep parameters and fatigue.
- Shorter sleep duration and longer time to fall asleep may contribute to decreased alertness among rotating-shift nurses.
- Differences in alertness decline across shifts may be linked to sleep quality and fatigue levels.
