How does an infrared sauna work?
Infrared light, or far infrared as it can often be called, is a wavelength of light naturally emitted by the sun. But whereas some wavelengths of light are visible, infared, or far infrared, is not. An example of the visible wavelengths from the sun is the light that you see when you see a rainbow. This is the visible wavelengths broken into their individual wavelengths for you to see. But you cannot see infared. Infrared is thermal radiation, meaning that it carries heat. The most common demonstation of this is one that everyone will recognise. You know how, when the sun comes out from behind the clouds there is an immediate sensation of heat on the skin? This is the warming effect of the infrared radiation from the suns light spectrum. A radiator or electric heater emits infrared light and therefore thermal radiation and this is what causes the heating effect. Or you may even have an infrared heater in your bathroom right now. Infra red radiation does not heat the air as some forms o
