Cedrus Saunas use Far Infrared energy to penetrate the body's tissue to a depth of up to 21/2". Tests have shown that the energy output is tuned so closely to the body's own radiant energy that our bodies absorb as much as 93% of the infrared waves that reach our skin.

By comparison, conventional saunas must rely only on indirect means of heat: first, on convection (air currents) and then, conduction (direct contact of hot air with the skin) to produce its heating effect. The Cedrus Saunas operates at temperatures of 110 to 130 F versus 180 to 234 F for hot-air saunas. Since conventional saunas require 30 to 90 minutes of warm-up before use, electricity costs are reported to be a lot higher than those of Cedrus Saunas which are ready to use in 5 to 10 minutes,
