Infrared Radiation By the Numbers
Re: There seems to be considerable points of contradiction with respect to infrared therapy.
Not surprising, since the infrared (redder than red) spectrum is wider than the color and ultraviolet spectra.
The ultraviolet (more violet than violet) spectrum is 390 nanometers across.
The color spectrum is 300 nanometers.
The infrared spectrum is 999,300 nanometers.
The near-infrared (NIR) spectrum by itself is 1,800 nanometers.
The mid-infrared (MIR) spectrum is 2,500 nanometers.
The far-infrared (FIR) spectrum is 995,000 nanometers.
The last three spectra are approximations since “experts” disagree where one category leaves off and another one begins.
Red visible light seems to be more healing than the infrared invisible spectrum, especially around 670 nanometers (basically the frequency of the commonest type of red laser pointer pen, which should NOT be used for therapy without knowledge of the hazards involved).
Mice have been cured of laboratory-induced blindness with 690-nanometer red light.
NIR radiation of various frequencies has been used to eliminate skin wrinkles with some success.
Red and NIR wavelengths protect plants from getting sunburned and definitely accelerate WOUND HEALING by resonating with mitochondria and other organelles, according to many “experts.”
Red and infrared are important constituents of Earth’s “radiation budget.”
A typical red chicken brooding light radiates EM wavelengths between 550-3,500 nanometers, mostly 700-1,100.
Natural infrared light from sunlight is almost exclusively NIR, and is especially abundant in the vicinity of chlorophyll-rich trees.
Satellites monitor chlorophyll in corporate crops with NIR spectroscopy on an ongoing basis.
Natural red and infrared radiation from sunlight is especially therapeutic at sunrise and sunlight, the Time of the Green Shadows, when most of the blue and violet light has been filtered out.
The green shadows and the occasional “green flash” of the setting Sun predominate over the color blue, which is scattered out of the line of sight.
I’ve instinctively sought out the healing power of the setting Sun’s rays, even before Swami Nitty-Gritty endorsed them in 1976 and before I was a lens polisher at Infrared Industries.
Blue light is critically important to set the circadian clock, but too much of a good thing is not our highest choice.
My knowledge of FIR “black body radiation” almost exclusively revolves around pheromones.
Human pheromones are emitted and received between 7,500-14,000 nanometers, the pheromone-detecting range of the nose.
Pheromones are also emitted and received between 15,000-26,000 nanometers.
A female cabbage looper moth emits the same FIR frequency as a candle flame (17,000 nanometers), dooming many a male cabbage looper moth to sex hot enough to turn him into a flaming fireball.
Be careful what you drag into an FIR sauna — you might fall “in love” with it.
