Far-infrared Technology: The far-infrared rays emitted by the far-infrared sauna are the same wavelength as the far-infrared rays emitted by the human body. Using this principle, it can react with the subcutaneous tissues and deeper parts of the human body through resonance effect, so that its temperature rises, thus activating the body's internal tissue cells and proteins, and has the effect of activating water molecules in the body.
