Abstract:
It is widely understood that mental stress produces various physiological changes. Though the relationship between mental stress and physiological response has been extensively reported, few reports have tried to clarify the relationships between various physiological responses and the intensity level of stress. In this study, we investigated autonomic nervous system activities to find a physiological index based on which we can evaluate the intensity of mental stress. As a result, we found that there were different response patterns for each physiological index. We consider that each physiological index shows different feelings and/or situations related to mental stress.
