Using within-subjects design, present study advances research searching interactions firefighters' sleep length, sleepiness, mood ratings function shift. We examined reductions length associated used scales to assess effects these reductions. Participants completed surveys throughout complete cycle their shift schedule. The showed firefighters working rotating 8-h schedule will less report lower positive scores, higher negative greater night Additionally, it was shown over course (two weeks), were unable adapt changes Finally, significant observed challenge historical, singular
