The advantage of the traditional medical field and their wide acceptance of infrared light therapy is that research began to develop it in regard to its (1) positive aspects, and (2) life-saving qualities, whereas unnecessary surgeries and dangerous medication had been used previously. A recent system of infrared light therapy uses a new combination of infrared light energy–non-visible forms and visible–called the Healthlight System.
The Visible Infrared Light is a system that is recognized as being able to reach about eight to 10 mm into the human skin surface, beneficial for many types of surface wounds, cuts, scars, triggers, treating infections, and also acupuncture points. On the other hand, the Invisible Infrared Light can reach a depth of about 30 to 40 mm, an area that involves bones, deep muscles, and joints. What all of this refers to is that both the red and the infrared wavelengths have the ability to reach different depths yet have similar therapeutic effects toward healing.
To give credit where credit is due, infrared light therapy is an ancient form of light therapy that originated when sunlight shining on bare skin was filtered through red stained glass. From then on, documentation shows us that more is known about infrared light therapy than any other treatment in history–red will stimulate the system as it is a base chakra color, the “fight or flight” area.
