Rank of Solar Waves or Energy
- Gamma, shortest rays, most destructive to life
- X-rays = Penetrate tissues, carcinogenic
- Ultraviolet = sunburn, corneal and lens damage
- Infrared: contains at the lowest end of spectrum, far infrared = lowest = 1000-5.6 microns; the rays most vital to healing are 4-14 microns, also are the majority of sun energy or photons (safest and most beneficial) responsible for photosynthesis; lowers lactic acid, stimulates brain, kills organisms, penetrates tissues, stops swelling, improves lymphatic flow, attracts calcium to cell membranes; detoxifies by vibrating ionic bonds and reducing the size of water clusters; by creating a resonance dance between water and chemical molecules, it facilitates water in moving stored toxins out of the cell and into sweat.
- Broadcast radio wavelength
Far-infrared radiant (FIR) heat is a completely safe form of naturally occurring energy that heats objects by a process called direct light, infrared heat or infrared energy. Direct light conversion warms only the object and does not raise the temperature of the surrounding free air. This type of energy penetrates 2-3" deep into the body and is tho9ught by some to increase circulation and nourish damaged tissue.
FIR heat is not ultraviolet radiation but a narrow band of energy within the 5-15 micron level. The infrared segment of the electromagnetic spectrum is divided into 3 segments of wavelength measured in microns or micrometers (a microns=1/1,000,000 of a meter); 0.076 ~ 1.5 microns = near or close; 1.5 ~ 5.6 middle of the intermediate; 5.6 ~ 1,000 = far or long wave infrared. The infrared segment of the electromagnetic spectrum occurs just below (infra) to red light. This band of light is not visible to human eyes but can be seen by special camera. We can, however, feel this type of light we perceive as heat. Our sun produces most of its energy output in the infrared segment of the spectrum Our atmosphere has a window in it that allows infrared rays in the 7-14 micron range to safely reach the earth's surface. When warmed, the earth radiates infrared rays in the 7-14 micron band with its peak output at 10 microns.
The sun is the primary source of radiant energy, but not all of this energy is beneficial. Although life needs energy form the sun, too much sunlight damages the skin. FIR heat provides many health benefits.
