Start with history of Red Light with Lasers and Serendipitous discovery
Why not just lay in the Sun? Peak Green, very little red and nir.
Penetrates deeper
It's essential for ATP and cellular energy/respiration.
Of ALL the frequencies from the sun that reach us on earth, 630-680 and 800-880 are the most essential!
Why? Because they literally drive our production of ATP and cellular energy!

LASERS
Albert Einstein first explained the theory of stimulated emissions of energy in 1917, which became the basis for the production of lasers.
In the 1940s and 1950s, scientists and engineers worked to produce a device based on the principles of stimulated emissions of energy, which was then called a MASER (microwave amplification by stimulated emissions of radiation), useful for its immediate application in microwave communication systems; additionally, they conceived of an optical Maser, or device for creating powerful beams of light using higher frequency energy to stimulate what was termed the lasing medium. As a result, the first laser was invented in 1960, using a Ruby as a lasing medium.
In 1967, Hungarian physicist Endre Mester pioneered laser medicine, including discovering the biological benefits of stimulated light energy on living tissues, including enhanced wound healing. Since that time, scientists and physicians have grown to understand more about the nature of stimulated light energy and its beneficial effects, all the while developing new techniques and devices for the use of lasers in medicine.

Tracing the history of Low Level Laser (light) therapy LLLT is a fairly recent journey that began with the discovery of the laser in the 1960's. The idea of the laser began in 1916 when Albert Einstein. Albert Einstein while considering the ramifications of the newly invented quantum physics, predicted that electromagnetic waves could stimulate atoms to emit more electromagnetic waves of the same wavelength. This is the theory of stimulated emissions and population inversion of energy, which became the basis for the production of lasers.

But it took several decades for technology to catch up with Einstein, but finally in 1960 Ted Maiman applied Einstein's principles and built the first successful working laser which was a flash lamp ruby laser (which was very small as shown here). From this device, the first ever pulses of red laser light were observed. Think about that, up until May 16th, 1960 the world had never seen laser light!

In the 1960s, the two different areas of science and research came together, with photomedicine and the newly discovered lasers being united in research within medicine.
First there was Leon Goldman of the University of Cincinatti, who began experiments on how lasers reacted with the skin[20], and researched whether they were able to remove tattoos [21]. What he found out was that lasers could do "bloodless surgery" and came to believe that high powered lasers were superior to steel blades for repairing wounded livers and removing damaged and dead tissue from burn wounds. For all this pioneering work, Goldman became known as the "father of laser medicine" [22].
Also in the early 1960s, Paul McGuff used this ruby laser to treat tumors. He was able to successfully ablate the tumors using a high power ruby laser. And he found his laser could not only cure experimental tumors but human tumors as well! McGuff's amazing result was published in the New England Journal of Medicine [23].

The Birth of Low Level Laser Therapy.
In Hungary, physicist Endre Mester set out to repeat Paul McGuff's anti-tumor laser treatment by trying to destroy tumors that were implanted in the bellies of rats.
But to his disappointment, he found out his laser was very low powered compared to McGuff's laser, so his attempt to destroy the tumors failed.
But then like many discoveries, he observed something completely unexpected with his low power laser. Because the mice were shaved, to test for skin cancer, instead of causing cancer, he saw the mice experienced increased hair growth and better wound healing (from the surgical incision) with a low power laser! This serendipitous discovery literally by accident was the first clinical demonstration and real birth of Low Level Laser therapy (or "cold laser") as opposed to high level or hot lasers that to this day are used in surgery, eyes, etc.
Mester also observed the anti-inflammatory effects of PBM, and he also further noticed that he could stimulate the cells that produce collagen. Collagen is the most abundant protein in the body and our body relies on collagen for regenerating tissue structure. This is one of the primary reasons LLLT is good for the hair, skin, nails and joints.
Mester furthered his research into laser therapy up until 1985 with many papers on wound healing both pre-clinical and clinical. Wound healing is another popular application of LLLT that continues to this day.

After Mester's landmark discovery, this started off a huge interest in research that has lasted right up until today which was initially called low level laser therapy (LLLT) to distinguish it from high powered surgical lasers used extensively nowadays for eye surgery. So there are many applications for using high powered lasers for cutting, heating and perform very surgeries and precise incisions.
Since then, medical treatment with coherent-light sources (lasers) or noncoherent light (light-emitting diodes, LEDs) has passed through its childhood and adolescence. Currently, low-level laser (or light) therapy (LLLT), also known as "cold laser", "soft laser", "biostimulation" or "photobiomodulation" is practiced as part of physical therapy in many parts of the world with research proven benefits from A-Z and head to toe

From LASERS to LEDS
NASA and LEDs
Light emitting diode (LED) technology was created towards the end of the 20th century, when NASA researched the effects of zero gravity (or very low gravity) on the health of cosmonauts. It was definitely established that gravity was an essential element of health for normal cell growth and functioning, and it was known wounds did not heal as well out in space as they did on earth. As we'll see in chapter 7, LED's stimulate cellular energy production in at least 3 fundamental ways leading to ATP production which is the currency of energy for all cellular activities. In one NASA study, DNA synthesis in fibroblasts and muscle cells quadrupled when exposed to LED light.

Special High Emissivity Aluminiferous Luminescent Substrate, or HEALS technology developed for NASA's commercial plant growth experiments in space is helping to treat cancer and save lives on Earth. NASA has partnered with Quantum Devices Inc. (QDI) of Barneveld Wis., to develop the WARP 75 light delivery system device for wound healing. A two-year clinical trial using the WARP 75 device on cancer patients undergoing bone marrow or stem cell transplants, concluded that there was a 96-percent chance that the improvement in pain relief of those in the high-risk patient group was the result of the HEALS treatment. The clinical trial was funded by NASA's Innovative Partnerships Program at the Marshall Space Flight Center in Huntsville, Ala. The NASA program works with industry and commercial partners to spinoff space technology and adapt it for new, innovative applications. (NASA/Higginbotham.
Most people nowadays are familiar with laser therapy and even low level laser therapy LLLT, but probably have not heard of photobiomodulation (PBM). The reason the name was changed back in 2015. First, it turns out you don't need a laser, as there is nothing really magical about laser beams. Since the vast proliferation of LEDs researchers realized that there is nothing special about a laser and LEDs work just as good or BETTER because of the ability to use higher total power over a larger area of the body (more on this later).
The other issue with the name LLLT is "low level", which is not well defined and it is a relative term. And finally because some of the applications do NOT involve stimulation, they involve inhibition, like inhibiting pain signals for example. So "modulation" is a much more apropos term which we'll explore in detail through this book. But in PBM, research still uses low level lasers, LEDs are fast surpassing lasers as the device of choice in research studies, mainly because of their affordability, and ability to cover a much larger area for healing then lasers which are frankly too focused and localized for many conditions. Though they will always have a place for spot treatments of all sorts and laser acupuncture.
As we'll see, because near infrared and red light therapy work with the body's innate biological wisdom to create balance and homeostasis, photobiomodulation (PBM) is a perfectly chosen word and throughout this book we'll use interchangeably PBM and RLT and only refer to lasers when talking of lasers specifically.
