The purpose of this study is to examine the effect of Far Infrared Rays radiation body. Natural Zeolite was reported as having excellent characteristics for manufacturing FIR radiation body. So we manufactured FIR radiation body using the following procedure: we used the burned powder of natural zeolite and a heat resistant binding agent to produce FIR paint; and then we applied the FIR paint to an aluminum plate. The FIR radiation body did not shed from the aluminum plate, and it had a high emission rate of greater than 80% at a wavelength of 5 to 25 micrometers. In addition, to investigate the difference of heat retention of the human body, we compared the temperature distribution of a FIR radiation heater, a thermal conduction heater, and a convection heater when applied to a human hand.
