Light is a form of energy that behaves like a wave and also as a stream of particles
called photons. Photons behave differently from conventional particles. They have
no mass and are not limited to a specific volume in space or time are electromag-
netic in nature though they have no charge. They interact with cellular tissue to
produce healthy changes in the body.

Living cells absorb these photons and transform their energy into adenosine tri-
phosphate (ATP), the form of energy that cells utilize for metabolism, synthesis of
DNA, RNA, proteins, enzymes etc for regeneration/proliferation of cells and ho-

The photons of different regions of the EM spectrum vibrate differently and have
different amounts of energy. Waves have different wavelengths as well. A wave-
length is the interval between two peaks of a wave, and relates to the color of visi-
ble light. For example, blue, green, red, and violet light have different wavelengths.
This difference becomes clearer when one compares red and infrared light. Red
light is visible but infrared is not.

Photon therapy is a simple, effective, non-pharmacological medical alternative to
prescription medicine or invasive surgery. It has been used in the horse industry for
almost 20 years for healing fractures and wounds. It helps acute/chronic injuries
and post operative wounds. It is common knowledge that sunny days are exciting
and dull ones, depressing. Not so well known is the fact that light—even in small
amounts—produces a multitude of clinical benefits, including tissue repair and
pain control.

The spectrum of visible light is very narrow compared to the invisible spectrum,
(gamma rays, x-rays, UV rays, infrared radiation, cosmic radiation, radio waves).
Gamma rays, x-rays, and UV rays tend to ionize matter and damage tissue because
their photons have high energy but radio waves have much lower energy and
longer wavelengths, and are relatively innocuous. Infrared and visible light fall

somewhere in between. Each photon gyrates and bounces at a unique frequency
and exhibits electrical and magnetic properties. As a result, their waves are called
electromagnetic (EM) waves.

LED’s (Light-emitting diodes) and LASERS are no more than convenient devices
for producing electromagnetic radiation at specific wavelengths. Lasers were in-
vented in 1960 and were produced using a technique known as Light Amplification
by Stimulated Emission of Radiation. Early research focused on high
power lasers, resulting in the weapons grade lasers and surgical lasers. Hot lasers
deliver power up to thousands of watts. They are used in surgery because they can
make a clean incision that cauterizes with no bleeding and can remove unhealthy
tissue without damaging surrounding tissue.

In the 1960s, an Hungarian physician, Endre Mester, attempted to use “high
power” laser to destroy tumors but failed. Instead, skin incisions appeared to heal
faster in animals treated with light. Skin defects, burns, and diabetic ulcers, venous
insufficiency, infected wounds and bedsores also healed faster. It turned out that his
laser was too weak to affect the tumor but stimulated the skin to heal faster—just
as sunlight may be beneficial in small amounts but destructive in high amounts. He
stumbled upon cold laser technology.

Cold lasers produce a lower average power of 100 milliwatts or less. This is the
type of laser that is used for therapeutic purposes and is often pulsed (turned on
and off) at so many pulses per second. LEDs do not deliver enough power to dam-
age the tissue, but they do deliver enough energy to stimulate a response from the
body to heal itself. These are called LED or SLD (super luminous diodes).

LEDs deliver the same healing wavelengths of light as lasers but with low peak
power output and can’t damage eyes like lasers. They also generate a broader band
of wavelengths to penetrate a larger surface area, affect a broader range of tissue
types and produce a wider range of photochemical reactions resulting in a faster
treatment time than laser.

Both visible red and infrared light in the range of 660nm to 1000nm have been
shown to effect at least 24 different positive changes at a cellular level. Photo ther-

apy stimulates the natural healing power of the cells in your body. It is absorbed by
chromophores such as cytochrome c, porphyrins, flavins, and other light-absorbing
entities within the mitochondria and cell membranes of cells. Once absorbed, the
energy is stored as ATP, the form of energy that cells use to repair tissue, reduce
pain, and restore biological normalcy. It helps healing by:-

* Creating new capillaries to carry oxygen and nutrients to the cell and waste
products away.
* Produces collagen so less scar tissue is formed.
* Releases ATP the major carrier of energy to cells. ATP accelerates the cell’s abil-
ity to accept nutrients and eliminate waste products. Food turns into ATP before it
is used by the cells. ATP provides the chemical energy that drives the chemical re-
action of the cell.
* Activates lymph system. Research shows that the lymph vessel diameter and flow
doubles with light therapy. The venous/arterial diameter can also be increased. This
means that both parts of edema (liquid and protein) can be evacuated at a much
faster rate to relieve swelling.
* Increasing RNA and DNA synthesis which helps damaged cells to be replaced
more promptly.

* Reducing the excitability of nervous tissue. The photons of light energy enter the
body as negative ions. This forces the body to send positive ions such as calcium to
go to the area which assist in firing the nerves, thereby relieving pain.
* Activates fibroblasts. Fibroblasts are present in connective tissue and form colla-
gen fibers which aids in the repair process.
* Increasing phagocyte cells which scavenge for and ingest dead cells from infec-
* Raises the temperature of the cells.
* Stimulating tissue granulation and connective tissue projections which help heal
wounds, ulcers or inflamed tissue.
* Stimulating acetylcholine release which causes cardiac inhibition, vasodilation,
gastrointestinal peristalsis and other parasympathetic effects.
* Modulating the levels of prostaglandin in inflammatory conditions, such as os-
teoarthritis, rheumatoid arthritis and soft tissue trauma.
* Regenerates nerves including the spinal cord once considered impossible to heal.

Visible red light, at a wavelength of 660 nanometers (1 nanometer = one billionth
of a meter), penetrates tissue to a depth of about 8-10 mm which is very beneficial
in treating problems close to the surface such as wounds, cuts, scars, infections,
trigger and acupuncture points.

Infrared light (904nm) penetrates to a depth of about 30-40 mm which makes it
more effective for bones, joints, deep muscle, etc. Infrared light is the invisible
spectrum below red from 700nm - 2,000nm.(sunny note: it penetrate more than 9 inches according to Prof Whelan)


The various tissues and cells in the body will only absorb light at specific wave-
lengths and not at others. For example skin, because of its high blood and water
content, absorbs red light very readily, while calcium and phosphorus absorb light
of a different wavelength.

Although both red and infrared wavelengths penetrate to different depths and af-
fect tissues differently, their therapeutic effects are similar. Depth of penetration is
defined as the depth at which 60% of the light is absorbed by the tissue, while 40%
of the light will continue to be absorbed in remote and internal areas of the body
through the stimulation of nerves, acupuncture and trigger points that perform a
function not unlike transmission cables.

With a 30 minute treatment researchers have documented increases in localized
circulation from 350% to 3200%! Cell proliferation occurs within 3 hours of expo-
sure. In osteo-arthritis with pain and limited range of motion, people notice a dif-
ference with only one 20 – 30 minute treatment. In most situations daily for a week
to ten days will bring changes. In the case of ulcers, total healing can be achieved
within 5 to 10 weeks - although not all ulcers respond positively.

In general, it promotes healing of skin, muscle, nerve, tendon, cartilage, bone,
muscle, cartilege, ligament, dental and periodontal tissues. It accelerates inflamma-
tion, enhances chondroplasia, upregulates the synthesis of type I and type III pro-
collagen mRNA, quickens bone repair and remodeling, fosters revascularization of

The literature indicates that light therapy may be beneficial in three general areas:

1) Inflammatory conditions (bursitis, tendonitis, arthritis, carpal tunnel syndrome,
arthritis, tennis elbow, golfer’s elbow).

2) Wound care and tissue repair (diabetic ulcers, venous and pressure ulcers, bed-
sores, mouth ulcer, fractures, tendon ruptures, ligamentous tear, torn cartilage).

3) Pain control (low back, neck and joint pain, post-operative pain, pain from in-
flammatory conditions, chronic pain syndrome, post-herpetic neuralgia, nerve in-

Doctor John Tate uses it every time he pulls a tooth because the lights help restore
circulation in the jaw.

Photodynamic therapy (PDT) is a cancer treatment modality that recently has been
applied for brain tumors. By injecting a photosensitizer, which accumulates in tu-
mor cells, then activating the photosensitizer with a light source such as LEDs, free
radicals are generated followed by cell death.

There is a dearth of scientific evidence that light therapy, when used at appropri-
ately low doses is therapeutic. The FDA has approved light therapy for the treat-
ment of head and neck pain, circulation, wounds and pain associated with CTS.
There are no known side effects, but suggested contraindications include treatment
of cancer; direct irradiation of the eye, the fetus, and the thyroid gland; and patients
with abnormally high sensitivity to light.

Clinical tests have been conducted by NASA, Stanford University, and the Mayo
Clinic, proving that photon therapy can help relieve pain and inflammation.

NASA developed LED infrared light to grow plants in space and these same wave-
lengths quintuple DNA synthesis in fibroblasts and muscle cells to
grow skin and muscle cells required by astronauts who lose bone and muscle mass
in long space flights due to lack of gravity.

The Medical College of Wisconsin in Milwaukee have used NASA’s LED lights
for removing brain tumors, hard to heal wounds such as diabetic skin ulcers, seri-
ous burns, and severe oral sores caused by chemotherapy and radiation.

“So far, what we’ve seen in patients and in laboratory cell cultures is that the near-
infrared light emitted by LEDs increases energy inside cells. This means whether
you’re on Earth in a hospital, working in a submarine under the sea or on your way
to Mars inside a spaceship, the LEDs boost energy to the cells and accelerate heal-
ing” said Dr. Harry Whelan, professor of pediatric neurology and director of hy-
perbaric medicine at the Medical College of Wisconsin.

“Some children who probably would have had to be fed intravenously because of
the severe sores in their mouths have been able to eat solid food,” said Dr. David
Margolis, an oncologist at Children’s Hospital of Wisconsin in Milwaukee. “Pre-
venting oral mucositis improves the patient’s ability to eat and drink and also may
reduce the risk of infections in patients with compromised immune systems.”

Navy Special Warfare Command centers in Norfolk, VA, and San Diego, CA found
40% improvement with musculoskeletal training injuries and 50% faster healing of

National Geographic Magazine™ calls light therapylight that heals “ in their
January, 2001 edition.

Imagine being able to regrow body tissue, help pain and circulation, wounds and
infections all in your own home without extra doctors’ bills and bringing no side
effects? For housebound people and those in pain, what a boon! In many cases
doctors have given a no-hope verdict to their patients - photon therapy gives new
hope to such people.
