What contributes to the uniqueness of infrared light? A form of electromagnetic radiation, infrared rays deliver considerably greater heat than ordinary visible light. More penetrating too, they’re the source of many practical applications. Also, infrared light is further categorized according to wavelength measurement. Such measurement of waves emanating from the sun identifies every form of radiation. Furthermore, measuring infrared radiation wavelengths has established three major types, from the shortest to the longest. Possessing wavelengths longer than visible light, all infrared radiation is invisible to the human eye and exists just beyond the “red end” of the visible spectrum. The infrared rays closest to visible light are shortest and, because of position, dubbed “near infrared. ” Still within the infrared frequency range, “mid infrared” rays are a bit longer, while those longest and farthest from visible are “far infrared. ” Though agreement on exact measurement standards for infrared wavelength categories is lacking, it’s been concluded that different lengths determine applications. Hence, some are more applicable to everyday usage than others. Near infrared technology underlies the fabrication of night-vision devices worn to compensate for a reduction in the visible light enabling humans to see. Near infrared sources augment available light by converting it into visible light. Thus, visibility in the dark is increased without an additional light source. A prime application involves goggles used by the military. Additionally, near infrared light heavily contributes to the field of fiber-optic telecommunications. Mid infrared, or mid-wavelength infrared, is widely used in guided missile technology. There, heads of infrared heat seeking missiles “home in” on the target aircraft through infrared cues, such as the exhaust plume of a jet engine. Meanwhile, the longest infrared light rays have been recognized as having the most application to natural health and wellness therapies. Indeed, far infrared light is often referred to as “thermal infrared. ” Near infrared radiation, despite its also being a form of radiant heat, is sometimes described as “reflective infrared. ” And although far infrared radiation does have reflective characteristics that can influence surface heating, its application to health therapies is most related to its deep penetration and absorption qualities. The emerging field of “energy medicine,” to which it belongs, has roots in ancient Chinese medical practices and wisdom. Though not identified as such then, ancient practitioners recognized that radiant heat, an accompaniment to far infrared light, could alter the balance of health.
Embracing this philosophy over twenty years ago, some European countries, the U. S. , and Japan began to openly recognize and promote the benefits of far infrared light. Indeed, the science of far infrared technology launched many new products: sun lamps, saunas, wraps, clothing, and an array of therapy treatments. Health results from the use of far infrared technology have been promising, extending easily to preventive, wellness and sports medicine.
