The FIR Dome can penetrate deep into tissues, resonate cells, and be absorbed by the human body. As a result, the body temperature is increased, capillaries are dilated and blood circulation improved, resulting in energy, restoration of physical strength, and pain relief.
The FIR Dome also helps cells regenerate and reduces inflammation in the body. FIR Heat Therapy is very beneficial for the body and is completely safe. source
The “Super Radiant Heating Surface” of the FIR Dome is covered with a very fine, multi-faceted, acute-angle silicon surface manufactured in New Mexico. When rays are scattered in all directions by the countless surfaces created by these silicon crystals, the effectiveness of the 160 degree span is amplified. The radiant transmission area is increased some 10-fold. source
