Experimental and calculated investigation on heat transfer in a low temperature sauna was made. Low temperature sauna was usually heated up by a radiation panel heater at the ceiling to 50 degree C. In order to examine how heat transfers from the radiation heater to a human body in a sauna room, temperature and velocity distribution air were examined by the experiment and calculation of indoor air flow. It was found that heat flowed from the radiation heater to the human body mainly through air convection and wall radiation, not direct radiation from the heater.
