Far infrared light is in the frequency of invisible light that is generated naturally by the sun. Far Infrared rays cannot be perceived by our eyes but can be felt as a gentle radiant heat. FIR Saunas differ from conventional saunas in that the heat from a FIR Sauna penetrates much deeper (about 1.5 - 2 inches deep) and causes more sweat to be released. Heating of the skin with FIR Saunas is much faster (in comparison with the conventional saunas).
Sweating is one of the most important excretory processes through which our body gets rid of toxins. With FIR Therapy, since the heat penetrates much deeper, it causes the fat cells and water molecules to vibrate and release stored toxins which then gets eliminated through sweat.
FIR Sauna therapy has been shown to improve cardiac and vascular function by up-regulating Nitric Oxide (NO) synthesis. NO causes the arteries which have become stiff to relax and improves circulation. FIR has been shown to reduce inflammation by inhibiting IL-6 and TNF-α (pro-inflammatory cytokines). FIR has also been shown to reduce oxidative stress in patients with chronic heart failure.
Other health benefits
FIR Therapy is extremely safe. Infrared waves are produced by our own body and by everyone else surrounding us which is how Thermal cameras are able to detect temperatures.
