Far Infrared Saunas have gained tremendous respect and renown among weekend cyclists, marathoners, weekend warriors and professional athletes alike. Far infrared sauna therapy has the unique ability to speed up and improve the healing process of many injuries, including joint and muscle pain, back pain, scarring, colds and flus as well as a host of other conditions. Far infrared sauna therapy penetrates the skin up to two inches to allow increased blood flow and vasodilation. During the sub-acute stage, far infrared sauna therapy permits a new growth of connective tissue and capillaries that help repair the damaged structures. Scar tissue also continues to grow during this time but can be minimized by the use of far infrared saunas. FIRT helps promote rebuilding of injured tissue by having a positive effect on the fibroblasts (connective tissue cells necessary for the repair of injury). Furthermore, it increases growth of cells, DNA syntheses, and protein synthesis all necessary during tissue repair and regeneration.
