WHAT IS A PHOTON?
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.
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-
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
This difference becomes clearer when one compares red and
infrared light. Red
light is visible but
infrared is not.
WHAT IS PHOTON
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
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
LED LIGHT and LASER
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
longer wavelengths, and are relatively innocuous. Infrared and
visible light fall
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
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
tissue without damaging surrounding tissue.
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.
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
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.
HOW DOES IT HELP HEALING?
Both visible red and infrared light in the range of 660nm to 1000nm have
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
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
* 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
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
* 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,
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.
HOW DEEP DO
Visible red light, at a wavelength of 660 nanometers (1 nanometer = one
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,
trigger and acupuncture points.
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.

situations daily for a week

PHOTODYNAMIC THERAPY FOR CANCER
(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.
IS IT SAFE?
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.
