要約(英語): The objectives of this study were to quantify changes in autonomic nervous function in shift workers after work using a finger plethysmogram and to evaluate their psychological states by means of psychological questionnaire. Eight female participated in the study. After a day shift (AD), after a night shift (AN), and on a holiday (OH) (referred to as “conditions”), the subjects' plethysmogram was continuously recorded while they performed tasks that would induce mental workload. Also, psychological questionnaire were conducted. The subjects engaged in four tasks: they gazed at a cross-shaped symbol on a computer screen (cross: “CS”), then they closed their eyes and rested (baseline: “BL”), they performed a mental arithmetic task (“AC”), and finally they rested (closed eyes: “CE”). The results showed that, the pulse wave amplitude during the “AC” task was significantly lower as compared to the figures during the “CS” task after a day and a night shift. The “CE” task was significantly higher than “AC” task after a day shift. The pulse wave length during the “CE” task was significantly higher than “AC” task after a day shift and on a holiday. The results of the psychological tests showed that fatigue levels were significantly higher than vigor levels after a night shift. These results suggest that the sympathetic nervous system becomes dominant during the mental workload after a night shift and that sympathetic dominance remains unchanged even after completing tasks.
