Although light (Photon) Therapy has been documented in medical literature as early as 1500BC, it was the Danish physician Nils Finsen, who is believed to be the father of phototherapy that received a Nobel Prize for his work in 1903. Since then, numerous authors have advocated treatment by phototherapy for many different diseases ranging from acne, vitilago, jaundice in babies, wound healing and rheumatoid arthritis to name only a few.
Throughout the ages, sunlight (as the earliest form of phototherapy) has been known to have both healing and wellness properties. Light is energy, and energy sustains life – it cannot be destroyed, but it can be transformed into other forms.
Photizo Light Therapy harnesses the healing power of red and infrared light at specific wavelengths & frequencies proven to be effective in accelerating natural healing of the body, reducing swelling and inflammation, stimulating the immune system and relieving pain. Cells that are injured can actually be rejuvenated by light.
Light Emitting Diodes (LED’s) have been around for a long time, but have only been introduced as a legitimate therapy option in recent years. LED’s are similar to lasers in that as they can emit the same light but differ in the way that the light energy is delivered. Lasers are focused-beam single-wavelength light emitters that can be intense enough (a ‘hot’ laser) to burn/cut tissue or ‘cold’ enough to only have light therapy effects. LED’s do not deliver enough power to damage the tissue, but they do deliver enough energy to promote natural self-healing and pain relief. With a low peak power output, the LED’s provide a much gentler delivery of the same healing wavelengths of light, as does the laser but without the same risk of accidental eye damage that lasers do.
LED’s are merely convenient devices for producing light at specific wavelengths, and several studies established that it is the light itself at specific wavelengths that is therapeutic in nature. All biological systems have a unique absorption spectrum that determines what wavelengths of radiation will be absorbed to produce a given therapeutic effect. The visible red and invisible infrared portions of the spectrum have been shown to have highly absorbent and unique therapeutic effects in living tissues.
LED’s also allow the light beam to spread out instead of being a pinpoint light beam. The wide-angle diffusion of the LED confers upon it a greater ease of application, since light emissions are thereby able to penetrate a broader surface area, and this results in a faster treatment time for a given area than laser.
Infrared light is one of the safest therapies on the market today. When infrared light is administered, it reduces sensitivity of neural pathways and causes the body to release endorphins that provide a nontoxic, natural form of pain relief. Unlike ultrasound and electrical stimulation, infrared technology is so gentle that patients can use it frequently without causing more damage to injuries or other chronic pathologies.
Light therapy has broad treatment applications. Using these devices, wounds and other injuries can heal faster and chronic conditions can be managed without the over use of pain and anti-inflammatory medications within a few treatments.
People with back problems, nerve damage, muscular diseases, tennis elbow, burns and other ailments have all shown marked signs of improvement using infrared light therapy.
The technology can also offset the long-term costs of surgery, pain medicines and physical therapy visits. We will be seeing infrared light used for all kinds of healing and pain control in the future. There will always be a place for medication and other modalities such as ultrasound and electrical stimulation, but now doctors will also start using light for treatment.
The FDA has approved light therapy for the treatment of head and neck pain, as well as pain associated with CTS (Carpal Tunnel Syndrome). In addition to these conditions, the literature indicates that light therapy may be beneficial in three general areas:
1. Inflammatory conditions (e.g., bursitis, tendonitis, arthritis, etc).
2. Wound care and tissue repair (e.g., diabetic ulcers, venous ulcers, bedsores, mouth ulcer, fractures, tendon ruptures, ligament tears, torn cartilage, etc).
3. Pain control (e.g., low back pain, neck pain, and pain associated with inflammatory conditions—carpal tunnel syndrome, arthritis, tennis elbow, golfer’s elbow, post-herpetic neuralgia, etc).
More about the light wavelengths used in Photizo Light Therapy:
Visible Red Light: Light that lie within the visible spectrum, from 400nm (violet) to 700nm (red). At a wavelength of 660 nanometers (nm – 1 nanometer is equal to one billionth of a meter), penetrates tissue to a depth of about 8-10 mm (about 3/8″). It is very beneficial in treating problems close to the surface such as wounds, cuts, scars, trigger points and acupuncture points, and is particularly effective in treating infections.
Infrared Light: Light in the invisible spectrum (below red), from 700nm to 2,000nm. Infrared Ray is not visible to the eye; it penetrates to a depth of about 30-40 mm (1.2″ to 1.4″), which makes it more effective for bones, joints, deep muscles, bursa, etc. Although both red and infrared wavelengths penetrate to different depths and affect tissues differently, their therapeutic effects are similar.
