TheraSauna® is made with non-toxic and non-allergenic Aspen Hardwood

Infrared energy heats objects (like your body and the inside wood of the sauna) directly and penetrates up to 2 inches below the surface. Cedar and redwood contain a natural insecticide within the wood called turpines. When these naturally occurring oils within the wood are heated, they gas off a substance called cedrine. Cedrine attacks the central nervous system of insects and kills them. It can also cause vomiting and convulsions in humans. TheraSauna® is made of Aspen, which is a clear wood grown at elevations where the trees do not produce an insecticide. Aspen is 99% non-toxic and non-allergenic.
