Generally, it is said that shaking a tip of a hand or a foot, that is, shaking a peripheral nerve of the tip of a hand or a foot can accelerate a relaxation state. Also, since many peripheral nerves are gathered in the palm and it is very sensitive, when you feel acoustic vibration with your body, applying vibration to the palm is preferable to applying vibration to other parts such as the thigh. The effect is great. Furthermore, as a movable sensible vibrator (for example, a cassette tape recorder), it is advantageous to consume less power, but the palm is sensitive as described above, so it is better to vibrate the thigh. There is an advantage that power consumption can be reduced as compared with the case where vibration is applied to other parts such as a part. In this way, applying vibrations to the palm of your hand helps create a relaxed state.
