A far infrared (“FIR”) sauna cabin equipped with a far infrared (“FIR”) heating elements constructed of ceramic, carbon, and/or light emitting diodes (“LED”), designed for therapeutic use in a sauna, capable of emitting far infrared energy, and heating an individuals skin for purposes of rejuvenation, anti-aging, weight loss, and acne therapy. The FIR heating element emits IR energy in a wavelength and frequency optimum for resonant absorption by the human body, resulting in the release of toxins stored within subcutaneous fatty deposits, which are then carried out of the persons system as he or she sweats. The FIR sauna cabin is further equipped with necessary hardware and tools to effectively create a more flexible environment in which the user can change seating configurations, move about more freely and conduct stretching routines or exercises within the sauna cabin, using specialized fittings integrated to the interior of the sauna cabin.
