On the surface, far-infrared light wave bath room and sauna room are very similar, but their working principles are different. There is an electric stove inside the sauna room, which generates high-temperature steam by splashing water, and the steam conducts heat to promote human perspiration. The principle of light wave bath room is to use far infrared radiation and light wave (slimming) bath room to simulate human biological spectrum information and scientifically configure five infrared radiation sources. Under the control of computer intelligent program, it emits 5.6 1.5 micron far infrared light wave, so that the light wave is fully absorbed by human body and penetrates the skin until the deep tissue makes it vibrate with human cells, and the human cells are massaged by light. The "static outside and dynamic inside" is supplemented by essential oil, nutritional cream, slimming cream, milk, petals and other nutritional factors, thus achieving the best effects of body adjustment, skin care and body shaping.
