We have examined how much tourmaline particle-impregnated pantyhose will affect human skin temperature when wearing it.

  Experiment 1 was carried out to examine the thermal behaviors of the sample and Experiment 2 was carried out to examine the effect by using a tourmaline-impregnated pantyhose and a non-impregnated one concurrently to compare their effects with each other, provided their composition and constitution are equal to each other in this case.

  The main results obtained through the 2 experiments mentioned above are as follows :

1. In case of the experiment by stably leaving a flagon for 75 minutes, the surface temperature of the flagon comprising the clothe of a tourmaline-impregnated pantyhose had risen approximately 1℃ higher than that of the flagon comprising the clothe of a non-impregnated pantyhose.

2. Also in case of the experiment by shaking a flagon for 10 minutes, the surface temperature on the front side of the flagon comprising the clothe of a tourmaline-impregnated pantyhose had furthermore risen approximately 1.5℃ higher than that of the flagon comprising the clothe of a non-impregnated pantyhose.

3. In case of the experiment wearing the pantyhose under a walking load kept at the advancing speed of 70 m/min for 20 minutes, the skin temperature on the front side of lower thigh wearing a tourmaline-impregnated pantyhose had markedly higher than that of the same part as the former wearing a non-impregnated pantyhose.

4. Also in case of the prior experiment wearing the pantyhose under the same walking load as mentioned above, the skin temperatures of these parts of a human body such as the lower thigh, ankle, toes of a foot, and the flow rate of blood of the toes of his foot, as well as the average skin temperature of whole body of his had been kept markedly higher in case of wearing a tourmaline-impregnated pantyhose than in case of wearing a non-impregnated one pantyhose.
