Sleepiness, Fatigue, Shift work scheduleAbstract
Sleepiness means a heightened propensity to fall asleep that increases with night work. Fatigue is a feeling of strain or exhaustion induced by effort that increases with day or night work shift. The aim of this study was to evaluate sleep duration, perceived sleepiness and fatigue, and other variables among permanent day and night workers. The data were obtained by questionnaires and actimetry. Workers didn’t differ significantly regarding sleep duration, but night workers perceived worse sleep quality and a significant increase in sleepiness. Increase of fatigue was significant for all workers, more pronounced for night workers. These results confirm the association of night work with disturbed sleep, sleepiness, and fatigue. Poor working conditions were associated with greater perceived stress, sleepiness, and fatigue. Evaluations of occupational safety and health should also cover workers sleepiness and fatigue and associated variables.
