| Tiivistelmä: | Fatigue has often been viewed as a simple variable that is positively correlated with time on task in the workplace and is produced mainly by physical activity. However, shiftwork researchers have demonstrated time-of-day differences for variables including sleepiness and mood, thereby challenging this notion of fatigue. Using a within-subjects design, the present study advances this research by searching for differences in time-of-day interactions in firefighters' sleep length, sleepiness, and mood ratings as a function of shift. |
