Abstract: A mid infrared radiation sauna is shown that includes a) a room, b) one or more elements able to emit infrared radiation; c) means for operating the elements; and d) a cover plate positioned between at least one of the elements and the open space of the room to be accessed by individuals.

Abstract: A mid-infrared radiation health appliance includes i) a first portion, and a second portion, the first and second portions being arranged with a space in-between for a user; the first portion including a first cover plate having an upper surface facing the space adapted for supporting the weight of the user; ii) one or more elements for emitting infrared radiation and mounted in the first portion, iii) one or more elements for emitting infrared radiation and mounted in the second portion; iv) means for operating said elements at least by turning each element on and/or off. At least one or more elements of each portion emits infrared radiation at a wavelength of within 6-14 microns during use. The first cover plate is made of either a thermoplastic or plate glass material that transmit more than 50% of incident infrared radiation in the wavelength spectrum of 6-14 microns.
