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.
