The purpose of this study is to investigate the effect of clothing pressure on physiological and psychological responses, to create an evaluating method of the clothing comfort. We have investigated the physiological and psychological responses to the clothing pressure in both situations which eyes open and eyes closed. The pressure amounting to 90% of the subjects' waist size was applied to their abdominal region by the waist belt. The influence of clothing pressure on physiological and psychological responses were evaluated by the following measurements: sensory test, electrocardiogram, electroencephalogram and blood pressure. Consequently, when subjects were fastened by waist belt, sympathetic nerve activity increased in case of eyes closed. On the other hand, parasympathetic nerve activity increased in case of eyes open. The physiological and psychological responses are different in eyes closed and eyes open conditions. The results mean that the clothing comfort on the pressure requires a sensory multimodality evaluation.
