If far-infrared waves are emitted from the sun and too much exposure to the sun is harmful, why are far-infrared saunas so beneficial?
True that excessive exposure to the sun can be harmful, but this has not to do with the infrared frequency but rather the ultraviolet frequency. Ultraviolet is responsible for the cellular damage associated with overexposure to the sun. Infrared however, is so safe that it is utilized in hospital neonatal unit incubators with newborns.
