Abstract

As a result of using a heat generator to experiment the physiological influence of the human body due to the warming effect of far-infrared radiation (FIR), the blood pressure of the subjects lowered and stabilized due the expansion of capillary vessels and salt discharge during perspiration as the temperature of the generator elevated($30{\sim}65^{\circ}C$). In case of heart rate, it decreased and stabilized when the temperature of the ‘far-infrared radiation heat generator’ was at a low temperature below $40^{\circ}C$. At a high temperature above $44^{\circ}C$, there was a slow elevation in the heart rate. However, the elevation of the heart rate is not a sudden elevation, therefore, does not give much stress to the heart.
