Abstract
Higher salivary cortisol levels were observed in sound engineers working very fast backward-rotating shifts compared to those on forward-rotating shifts.
- Salivary cortisol retained a typical daily pattern across all participants.
- The rotation direction significantly interacted with shift timing, affecting cortisol levels.
- Engineers on backward-rotating shifts reported worse sleep quality.
- Higher cortisol values during morning and night shifts in the backward-rotating group may suggest insufficient recovery.
- Ratings of stress and fatigue were monitored alongside cortisol assessments.
