Also, the main point of that is that the water aspect of the wavelength of 1072nm is that the LED light is being absorbed at that frequency "within" the body. I believe that that is the "mechanism" by which they believe the efficacy is created of a 1072 nm LED.

If you put a bag of distilled water as a filter, would you not in effect defeat the purpose and hence the infrared heat lamps energy would all be absorbed in the water, with no useful energy passed along to you?
