A portable compact sauna wherein a user's body is warmed to sweating primarily by direct absorption of infrared radiation. Broad infrared radiation emitters or sources are placed around the inside of a narrow cabinet so as to be in close proximity to various parts of a seated user. Fins spaced apart less than finger-width on the emitters protect the user from contact with elevated temperatures in the emitters. The emitters, which lend themselves to easy cleaning, are heated by electric infrared heaters having a unique design which eliminates extremely-low-frequency (ELF) electromagnetic field (ELF) normally generated by AC energized electrical heater elements, to provide low extremely-low frequency EMF saunas able to utilize conventional-commercial electrical-energy sources. The emitters protect the heaters. Power wires for the heaters are arranged for low ELF EMF emission, too.
In a compact sauna for causing a user to sweat, infrared source elements disposed in close proximity to the user so that infrared radiation absorbed by the user constitutes the primary means for inducing the user to sweat.
An infrared heater comprised of two sets of parallel electrically-resistive bars, the corresponding bars of the respective sets being juxtaposed, electric conductors interconnecting corresponding ends of the bars, and connectors for applying 180 degrees out of phase electrical current to the respective sets of conductors so that current flows in opposite directions in corresponding bars at any given point in time.
A finned infrared source comprised of a base adapted to be heated to uncomfortable-to-the-touch but sufficiently-high temperatures to provide effective infrared radiation, and closely-spaced protrusions of a low heat-conductance material which project away from the base and present temperatures comfortable to the touch even though the base is at uncomfortable temperatures.
A method of sweating a person, comprising primarily heating the person by direct infrared radiation absorption.
An extremely-low-frequency electro-magnetic-field power wring for connecting an alternating current source to a load, comprising a first electrical conductor for supplying the alternating current from the source to the load and emanating an extremely-low-frequency electromagnetic field when so doing, a second electrical conductor for returning the alternating current from the load to the source and emanating an extremely-low-frequency electromagnetic field when so doing, the first and second electrical conductors being juxtaposed so that the extremely-low-frequency electro-magnetic fields when obtaining cancel each other, and an electrical insulator separating the two conductors.
