The main difference between near-infrared and far-infrared saunas lies in the wavelength of the infrared radiation they use:
Near-Infrared Saunas: Near-infrared saunas primarily use near-infrared light, which has shorter wavelengths and is closer to visible light on the electromagnetic spectrum. These saunas often feature incandescent or LED bulbs that emit near-infrared light. Near-infrared is thought to penetrate the skin more superficially, promoting skin health, collagen production, and potentially providing localized benefits.
Far-Infrared Saunas: Far-infrared saunas use far-infrared radiation, which has longer wavelengths and is closer to microwave radiation on the electromagnetic spectrum. They typically have heating elements that emit far-infrared heat, which penetrates the body more deeply and is believed to generate internal heating and promote more significant health benefits, such as improved circulation, pain relief, and detoxification.
Both types of saunas are designed to provide therapeutic effects, but they may have different applications and potential benefits based on the wavelength of infrared radiation they primarily emit. Some saunas combine both near and far-infrared elements to offer a broader range of benefits. Individual preferences and health goals can influence the choice between near-infrared, far-infrared, or a combination of both.
