Abstract
We investigated the influence on the physiological response of clothing pressure from a fastened waist belt under several luminance conditions. Brain activity and autonomic nerve activity were evaluated by electroencephalogram and electrocardiogram measurements. From the results, in the case of high luminance, the brain wave has a tendency to shift to fast wave activity, and the autonomic nerve activity response to stimuli of pressure sensation was striking. When the luminance was lowered at the same time that the clothing pressure was applied, the pressure sensation had a greater influence than the visual sensation on the physiological response. When the luminance was heightened, the visual sensation had greater influence than the pressure sensation. From the viewpoint of homeostasis, when evaluating stress using autonomic nerve activity, we should not make the judgment that increases in parasympathetic nerve activity are relaxed conditions, but should consider stress as changes from the normal conditions.
