Abstract
Use of a massage chair to relieve the muscle fatigue is useful also for the relief of a mental stress. The comfortableness improvement after the chair had been used was evaluated with physiological index. However, individual difference was shown and constant tendency of physiological response to the comfortable was not obtained. Then, thirty subjects were measured and their response was made the grope by the physiological index. As a result, it was clarified that the tendency to the rise of the skin temperature and the heart rate decrease became an evaluation index in the effect of the massage.
