What is Infrared Light Therapy?

Infrared Light therapy or Phototherapy, is the treatment of a disorder by exposure to specific wavelengths of light using light-emitting diodes(LEDs), controlled with various devices. The light is administered for a prescribed amount of time.Light therapy has been shown, in over 40 years of independent research worldwide, to deliver powerful therapeutic benefits to living tissues and organisms. In the same way that plants use chlorophyll to convert sunlightinto plant tissue, light emitting diodes(LEDs) can trigger natural intracellular photobiochemical reactions in our bodies. Plants must have the sunlight to grow. Our cells benefit from light therapy.

Photo-stimulation was first discovered in the 1960s when European scientists began to use light beams of specific wavelengths and frequencies to treat damaged cell tissues. Today, that technology has been harnessed into portable,light-emitting diodes(LED) hand-held units, and full-body units.

Studies show when light therapy breaks through blocked energy, and the light enters and stimulates the cells as photons. The photons are absorbed by the photoreceptors within the cell. Photons strike the damaged tissue including skin, blood, muscle, and bone, and create a cellular response which reduces pain and jump-starts the healing process.

The use of monochromatic low intensity infrared laser and LED diodes has been promoted in several countries for many years as an effective treatment for arthritis, soft tissue injuries and pain. Infrared Diode Therapy has been used as a monochromatic device since around 1960. It was not until 1998 that PAIN-X-2000 (Polychromatic Infrared Diode) Therapy was developed and first used in the United States.

It is becoming increasingly rare to find a physiotherapy department or clinic without access to this modality.Polychromatic Devices are being used by Medical Doctors, Nurses, Veterinarians, Equine Therapists, Chiropractors, Anesthesiologists, Dentists, Massage Therapists, Physical Therapist, and many more. More and more publications within the medical and scientific community attest to the clinical usefulness of these devices and their many biological effects upon the cells.

Principles of phototherapy were established at the end of the nineteenth century by NR Fineness, a Nobel Prize winner, for application of light treatment of psoriases, kemicterus, and as photodynamic therapy (POT). Phototherapy was advanced with introduction of laser treatment, initially in surgery. The development of the infrared (830 nm) gallium-aluminum-arsenide and the red (633nm) helium-neon low power laser, introduced phototherapy in wound healing and analgesia. Many investigators have described successful pain treatment in a variety of diseases.

Both visible wavelengths(Red, Green, Yellow, Orange, Blue),and invisible to human eye wavelengths (infrared) have been shown to effect at least 24 different positive changes at a cellular level. Visible light penetrates tissue to a depth of about 8-10 mm. It is very beneficial in treating problems close to the surface such as wounds, cuts, scars, trigger and acupuncture points and is particularly effective in treating infections. Infrared light (904nm) penetrates to a depth of about 30-40mm which makes it more effective for bones, joints, deep muscle, etc.

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 a manner that is less fully understood. Treating points with light can have a dramatic effect on remote and internal areas of the body through the stimulation of nerves, acupuncture and trigger points that perform function not unlike transmission cables.

The technology is now becoming accepted and widely used in human medicine as well. Light therapy stimulates the natural healing power in the cells of the body. This tool uses the energy of light, called photon energy, to stimulate the activity of certain cell components. By using photo energy, you have a simple, effective, non-pharmacological medical alternative. Conservative management of acute and chronic injuries and postoperative wounds has come to include the use of photo energy because it is quickly effective, cost effective, and easy to administer.

Light is energy that moves in a wave pattern. Light is also characterized by its wavelength in the electromagnetic spectrum. PAIN-X-2000 products are available in red, orange, yellow, green, and blue which lie in the visible spectrum. These therapeutic colors of photo energy lie between the infrared and ultraviolet wavelengths. This combination of infrared and visible light wavelengths is believed therapeutic. There are components in the tissue and blood that absorbs these wavelengths and activate normal cell activity that may have been disrupted by injury or sickness. The reason for this increased cell activity is the photon. The photon is the energy portion of the light wave. For this reason we often refer to this therapy as PHOTON THERAPY.

Infrared therapy utilizes light energy in the invisible range of light. Infrared rays are just beyond the visible red range of light in the spectrum, thus we cannot see the Infrared light emitted from the treatment unit. Virtually all light has some penetration properties; however, it is often absorbed by the outermost skin layers. Traditional thermal (hot) laser light, on the other hand, can penetrate but often destroys tissue. Since damaged cells benefit from light, the objective was to develop a non-thermal and nondestructive deep tissue delivery vehicle—hence Infrared Light Therapy.

Once delivered, the light energy promotes the process of photobiostimulation. The positive effect of photobiostimulation on animal cells is analogous to photosynthesis in plant cells, whereby a chain of chemical reactions are set in motion. In human tissue the resulting photochemical reaction produces an increase in the cellular metabolism rate which expedites cell repair and the stimulation of the immune, lymphatic and vascular systems. The net result, observed in clinical trials to date, is the apparent reduction in pain, inflammation, edema and an overall reduction in healing time.

Future LED Applications

Much research is underway on the use of medical LED therapy to determine whether there are other applications for light therapy. "Research is currently being done on the different effects of different spectrums of light on living tissues," says Braden. It is thought that the visible red spectrum, which is roughly in the 600 to 700 nanometer range, is effective with surface issues such as wound care and that higher wavelengths, including infrared, are more penetrating. Studies also suggest that going down to the 400 or 500 nanometer spectrum, which is blue light, might be effective for treating skin disorders including acne and scarring.

"We've already seen how using LEDs can improve a bone-marrow transplant patient's quality of life," said Dr. Harry Whelan, professor of neurology, pediatrics and hyperbaric medicine at the Medical College of Wisconsin. "These trials will hopefully help us take the next steps to provide this as a standard of care for this ailment."

"Companies in this business are looking at the medical research that is being conducted regarding different frequencies of light to see where this technology might take us," says Braden. He foresees wound care as being the next big application. "You can expect over the next few years to see LED therapy as being the primary treatment for wounds such as post-surgical and non-healing wounds like diabetic ulcers." Whelan and Ignatius say they would like to test their technology in other clinical situations such as spinal cord injuries and for treatment of Parkinson's disease, strokes, brain tumors, and tissue and organ regeneration.

"It may seem strange to some people because it is very much a change in the whole paradigm of medicine, which has been pretty much poisons and knives up until this point. The use of natural energy at an intensity that is brighter than the sun, but still nonetheless near infrared light at wavelengths that are helpful and not harmful, to enhance the cells' natural biochemistry truly has a lot of potential in the medical arena," says Whelan.

Studies have proven that Infrared Light aids:

Fighting Mucositis with LED Lights From 27 ABC Updated: June 12, 2008 04:32 AM CDT

Four year old Delaney (duh lane ee) Dikeman (dike min) is recovering from severe aplastic (ay plastic) anemia. "They did a blood test and all of her cell counts were low." Delaney needed a bone marrow transplant from her baby sister. It required the destruction of delaney's immune system using chemo, leaving her susceptible to severe mouth sores. "Mucositis is one of the most painful side effects of cancer treatment and it essentially occurs in all patients with bone marrow transplant regimens to a fairly severe extent."

The medical college of wisconsin is testing near-infrared technology to see if it can prevent mucositis (myoo co sigh tiss) by reviving and re-energizing damaged cells. "The cells have been attacked by the treatment of the cancer, and now they're in an energy crisis. if the light is able to help them over that energy crisis so they can heal faster, we can actually heal the mucus membranes." Hundreds of tiny l-e-d chips emit near-infrared light. The light isn't hot, but it is powerful. "We're able to administer light that can be over ten times as bright as the sun, but just at the helpful wavelengths." For delaney's mom, the light treatment was a way to help her daughter and advance the science. "She had a couple of sores, but that was about it, and from my understanding, it can be a lot worse than what she had." Ultimately, a small glimmer of hope that helped heal this little girl. In addition to the national study on mucositis treatment, the Wisconsin researchers are investigating whether this light therapy may treat other conditions such as parkinson's disease.

Why Use LEDS?

Our Infrared Therapy products use LEDs instead of Lasers. Lasers have a focused beam (as used for eye surgery) that produces a narrow bandwidth of radiation that generates the light. The laser light is called "coherent" because the light waves are "in step" with each other, which is called coherence. Picture the laser lights as a single column penetrating to a specific point within the target area.

The LEDs in our products are non-coherent which is electromagnetic radiant energy not all of the same phase (not in a column, but an array), and can consist of various wavelengths.

Lasers and Infrared LEDs have different wavelength configuration, but they both disburse in the body when the light enters. The difference is in the wavelength and the density of the energy. The LED array reaches a larger surface area.

The laser actually delivers substantially less energy per unit of time because of the duty cycle of the LED. The LED's duty cycle is 2.5 million times longer than a laser of comparable wavelength. Lasers are also expensive to produce.

Because lasers were used in early research, we see names such as low level laser, infrared laser, cold laser, low level light laser, and low power laser where we read about photon therapy. The term laser therapy is not all together appropriate for the photon therapy used today. Remember what is important is the type of energy produced which creates the biological effect. Bear in mind it is the interaction of light photons and molecules within the cell that creates cellular activity. LED's will penetrate just as deep as a laser. Once the laser enters the skin it is no longer a columated beam of light so it does the same as the LED's except the LED's have a wider viewing angle and cover a larger area than a single laser beam.

Most lasers produce a brilliant visible red light. The can be large and expensive. Most popular tools available today do not require this type of brilliant light emitting equipment, but use semi-conductor diodes. Our light-emitting diodes are less expensive and tiny, by comparison. They are also extremely safe.

Many proponents of lasers say that light must be coherent. While this may be a controversial question to some, remember living tissue has its own coherency factor. This coherency factor is much higher than that of the light therapy. We believe this cancels the coherency factor of the incoming light. This light then becomes scattered. If the coherency is lost when it passes through the first layer of tissue, then the distinctive tissue such as the nerves, muscles, blood, and or connective tissues absorb light which are non-coherent. Basically the tissue at this point does not know if the light was emitted from a coherent or incoherent source. To quote David Olszewski from the book Light Years Ahead "LED's are increasingly replacing cold lasers, as they demonstrate comparable effectiveness without the laser's side effects. There is concern with the use of even soft lasers in terms of potential harm around negative side effects. They can be harmful if overused or if they come in contact with the eyes." He also is stated as follows, "LEDs give a larger light dispersion beam and allow a greater margin of error in locating and activating the acupuncture point".

In his paper, Laser Therapy: Infrared Photo Energy May Reduce Neuropathic Pain, by Thomas J. Burke, PhD, he states that diabetic neuropathy is a common health problem today which often poses a variety of clinical challenges. Dr. Thomas J. Burke reports on the results of a study utilizing phototherapy (non-coherent light therapy) on patients with neuropathies. There is a rapidly increasing body of evidence that is demonstrating the clinical value of using non laser light therapy for a wide variety of painful conditions..

The studies of LED therapy by NASA states: "Lasers, however, have some inherent characteristics that make their use in a clinical setting problematic, such as limitations in wavelength capabilities and beam width. The combined wavelengths of light optimal for wound healing cannot be efficiently produced, and the size of wounds that may be treated by lasers is limited. Light-emitting diodes (LEDs) offer an effective alternative to lasers. These diodes can be made to produce multiple wavelengths, and can be arranged in large, flat arrays allowing treatment of large wounds. Potential benefits to NASA, military, and civilian populations, include treatment of serious burns, crush injuries, non-healing fractures, muscle and bone atrophy, traumatic ischemic wounds, radiation tissue damage, compromised skin grafts, and tissue regeneration."


When this therapy reached the U.S. and Canada, both lasers and light-emitting diodes at 660 nanometers were being used. The LED diffuses; the single frequency laser does not. With this diffusion, the cell can actually be in control of the treatment and shut off the molecules when it was done. But with the laser, the cells are no longer in control; the doctor or the practitioner applying the laser is in control. If he does it too long or with too much strength, you would not only heal the tissue, but you would start a deterioration again. So basically, the use of light-emitting diodes eliminated the draw back of lasers, and light could be applied into such sensitive areas as the eyes and around the face. LEDs allowed this whole area to blossom into a much larger usage by average people in their homes. Tiina Karu, Ph.D. of the Laser Technology Center in Russia, and affiliated with the University of California at Berkely, probably the top researcher in the world on the use of lasers and light emitting diodes published a study in Health and Physics Digest called "Photobiological Effects of Lasers" which discusses photobiological stimulation without laser light. The article explains that you can do laser treatment without using laser light, by using light emitting diodes which are much safer. Since the cells are basically in control of the process, there is no way to overuse light.

Facts about Wavelengths/frequencies/colors

The different types of tissue and cell types in the body all have their own particular light absorption values and characteristics. These tissue and cells will only absorb light at specific wavelengths. This is one of the reasons that PAIN-X-2000TM used the Patented Polychromatic Process (using more than one color; this can also mean that it contains radiation of more than one wavelength.) Superluminous LEDs (Light Emitting Diodes) are safe concentrated light sources used to produce the specific wavelengths of light that provide therapeutic benefits of light therapy without adverse side effects.

The diverse tissue and cell types in the body all have their own unique light absorption characteristics; that is, they will only absorb light at specific wavelengths and not at others. For example, skin layers, because of their high blood and water content, absorb red light very readily, while calcium and phosphorus absorb light of a different wavelength.


The University of Chicago researchers discovered that the average wavelength of cell tissue in the human body ranged between 600 nanometers and 720 nm; 660 is the mid-point.

Excellent studies have been done using light for pain relief, degenerative osteoarthritis, carpal tunnel tendonitis, skin ailments, acne, psoriasis, healing of the sinus cells, throat and ear problems, whiplash and lower back problems.

The red and infrared diodes are absorbed by the skin, muscles, tissues, bone as well as working at the physical cellular level. Visible red light, at wavelengths from 630 to 700 nm, is very beneficial in treating problems close to the surface such as wounds, cuts, scars, trigger and acupuncture points, and is particularly effective in treating infections. Infrared light (800 to 1000nm) penetrates deeper which makes it more effective for treating organs and provide relief for ailments of bones, joints, deep muscle tissue.Although both red and infrared wavelengths penetrate to different depths and affect tissues differently, the therapeutic effects are similar.

The green diodes are absorbed by the Bio-Electro-Magnetic Energy Field (E-Field) which surrounds the body. It is here that the stress and strain build up and develop into "weak spots." If these spots are not eliminated from the E-Field, eventually under hard work or performance pressure they can become problem areas. Green is also considered a master color and has reported usefulness as an anti-inflammatory as well as for painful joints and allergies.

The orange light is considered a rejuvenating color. It can help with muscle cramps and boosts energy in the lungs and stomach.

The yellow lights can be great stimulants for the sensory and motor nervous system, as well as toning muscles. It helps to increase your energy state. It, reportedly, helps relieve arthritis pain and improves the lymphatic system.

The blue lights are believed to be contractors and restrictors.They have reportedly help with inflammation, acne, burns, headaches, fever, etc., as well as provide a calming and relaxing effect. In addition to the Blue 9 LED, other models have blue lights available in the switchable model.

There are many other colors that are used in color therapy, however, we feel at this time the combination we have developed are appropriate for general use.The "warm colors" are of positive polarity and the "cool" colors are of the negative polarity.

Is it safe?

Our Infrared Light Therapy products are completely safe to use. So safe, in fact, that the FDA has given them the clearance for human infrared therapy. There are no known side effects to this treatment. Patients who are pregnant or who might be pregnant, and patients with active malignancy (cancer) should avoid this therapy.

Read the studies of LED therapy by NASA. "Long term space flight, with its many inherent risks, also raises the possibility of astronauts being injured performing their required tasks. The fact that the normal healing process is negatively affected by microgravity requires novel approaches to improve wound healing and tissue growth in space. NASA LED arrays have already flown on Space Shuttle missions for studies of plant growth and the U.S. Food and Drug Administration (FDA) has cleared human trials."
