Thermographical comparison of skin surface temperatures in the lumbar region 12 minutes after commencement of irradiation with water-filtered infrared-A (left) and conventional infrared (right) with the same irradiance: the skin surface temperature is higher in the case of irradiation with conventional infrared (presented in the thermography), while the temperature at 1 cm tissue depth is higher when irradiating with water-filtered infrared-A (from [1], [20]). Water-filtered infrared-A thus leads to a high tissue penetration combined with a low thermal load to the skin surface.
