Most of the light that we see every day is actually a combination of different types. All the lights are electromagnetic waves. Wavelengths of light will determine their properties. Lights can be visible or invisible. The visible lights can be a variety of colors. Shown in the picture below you can see, the Sun lights spectrum ranges from ultraviolet and violet on the short wavelength side, the red and infrared long-wavelength side.

Different types of light interact with our body differently. In general, the smaller the wavelength of light, the more damage to living cells is caused. Lights, like ultraviolet, are very harmful to living cells. The most beneficial lights are those whose wavelength is close to the red light. Far Infrared Therapy, FIR therapy or Infrared Therapy uses far infrared light, which is part of the sun light spectrum whose wavelengths fall just below (the word Infra means), visible red light.
Although the wavelengths of FIR are too long for the eyes to see, we can experience its energy as gentle, radiant heat, which can penetrate up to [3.5] inches beneath the skin. So Far Infrared Therapy, or FIR Therapy is also a kind of light therapy and heat therapy, it works to improve health using the following principles:
Improves the microcirculation by soothing blood vessels
Increases the supply of oxygen and nutrients in blood cells to areas of the body's soft tissues
Improves functioning of white blood cells, which increases the immune response and elimination of foreign pathogens and cellular debris
Removes accumulated toxins by improving lymph circulation which are often at the core of many health problems. The build up of toxins in a health body could block the normal blood circulation and impair the cellular energy. When FIR waves are applied, the water molecules that encapsulate the toxins get heat up, and start to vibrate. This vibration reduces the ion bonds of the atoms that are holding together the molecules of water. As the breakdown of the water molecules occurs, encapsulated gases and other toxic materials are released and the body gets rejuvenated
Promotes regeneration and fast healing
Increases metabolism between blood and tissue
Stimulates the hypothalamus, which controls the production of neuro-chemicals that are involved in such biological processes as sleep, mood, pain sensations and blood pressure
