I first heard about near infrared light in an interview Dr Mercola had with Dr Michael Hamblin. It was so interesting that I continued to study it and tried several ways to apply the ideas.
Now I use a Vielight – a manufacturer of several types of infrared lights. I have been using the Gamma Vielinght for almost 2 years. It cost about $1,700 and I use it about 5 days per week. It cleared up my neuropathy completely and I sleep much better.
Here is the interview I first heard:
Near Infrared light http://mercola.fileburst.com/PDF/ExpertInterviewTranscripts/Interview-MichaelHamblin-Photobiomodulation.pdf
Dr. Michael Hamblin, who is an expert in this area, has quite a prestigious background of credentials as a researcher. He’s an associate professor at Harvard Medical School.
Dr H: Infrared therapy is part of photobiomodulation. The most commonly used wavelengths of light are what we call the near-infrared which starts [at] about 750 nanometers and goes all the way into maybe 1,200 nanometers.. It also penetrates well into the body Other colors of light, like blue and green, have a biological effects, but they don’t penetrate as deeply.

Low-Level Light/Laser Therapy Versus Photobiomodulation Therapy
Sunlight has much anecdotal use in ancient scriptures. In the late eighteenth century, Niels Ryberg Finsen pioneered the use of red and blue light to treat various human ailments, especially Lupus vulgaris. He was awarded the Nobel Prize in medicine and physiology in 1903 for his pioneering demonstration that concentrated chemical rays from sunlight could be bactericidal as well as stimulating surrounding tissue
The second major milestone in therapeutic use of light began in the early 1960s.3 .. Mester et al. noted that laser light at low doses demonstrated increased hair growth at an accelerated rate, and promoted wound healing.
In addition to biostimulation, a few of the other names previously used for this therapy have included low-level laser (or light) therapy (LLLT), low-intensity laser therapy, low-power laser therapy, cold laser, soft laser, photobiostimulation, and photobiomodulation.
The use of the term photomodulation distinguishes the nonthermal, from simple heating of tissues that can be accomplished using near-infrared (NIR) lamps.
The definition for photobiomodulation therapy – “A form of light therapy that utilizes non-ionizing forms of light sources, in the visible and infrared spectrum. It is a nonthermal process involving endogenous chromophores that results in but is not limited to the alleviation of pain or inflammation, immunomodulation, and promotion of wound healing and tissue regeneration.”

Many ancient therapies have applied sunlight for wound healing and pain relief. The spectrum of sunlight in the environment and the corresponding water absorption spectrum are shown below
Since the human body is made up of 70% water, it can potentially accumulate a large amount of energy that could modulate biological processes by sunlight
