What is the main difference between far infrared and convectional heat with regard to temperature?
Far infrared systems emit their energy in long micron wavelengths, convectional heat releases their energy in short wavelengths, like your oven. The main difference is far infrared light heats the body and not the air like a convectional system. Therefore you can enjoy your sauna at a much lower ambient temperature and receive more effective and efficient heat therapy.
