But is 300 watts necessary? That is a heck of a lot of power to be pumping into one's body, a person normally generates about 100 watts of heat, so that would increase their heat load by 300%. The body would have to dissipate 4X as much as as normal, and if using it on an extremety could result in overheating or even cooking I would think. > > One question worth asking is what kind of electromagnetic field do they > generate?

It is similar to the radiation you feel coming off of a hot pan and will contain both far as well as near infrared. Use of some cotton between it and your body will eliminate the near infrared (that has very little penetrating power), leaving the deep penetration far infrared. Refrigerators are being made with far infrared compartments for meat. They claim that the far infrared increases the nucleic acid in meat, making it maintain it's taste longer. This could be a hint on what it does in the body as well. Also there is a paper on pasturization using far infrared, which might mean it is capable of killing pathogens in the body as well: TI Far-infrared irradiation effect on pasteurization of bacteria on or within wet-solid medium AU Hashimoto, Atsushi; Igarashi, Hideo; Shimizu, Masaru AF Tokyo Univ of Agriculture & Technology AC Tokyo AY Jpn SE J Chem Eng Jpn ST Journal of Chemical Engineering of Japan SN 0021-9592 CN JCEJAQ IG 0078972 ISL n 6 SD Dec VOL v 25 YR 1992 AT (Author abstract) NR 9 Refs AB The present purpose is to study the influence of far-infrared irradiation on pasteurization of Escherichia coli and Staphylococcus aureus on or within a model for wet-solid food. Agar medium was used as the food model. By determining the thermal resistances of the test bacteria, the pasteurization effect of far-infrared irradiation (radiative heating) was compared with that of hot-air heating (a conventional method) from the viewpoint of thermal death kinetics. It was found experimentally that far-infrared irradiation is more effective than hot-air heating for the test bacteria on the agar-plate.
