How can light therapy help you?

Posted by Megan Kelly on

Throughout the ages, sunlight, which is actually 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 and 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 (LEDs) have been around for a long time, but have only been introduced as a legitimate therapy option in recent years. LEDs 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 (hot) enough to burn/cut tissue or ‘cold’ enough to provide only light therapy effects. LEDs 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 LEDs provide a much gentler way of delivering the same healing wavelengths of light as the laser, but without the same risk of accidental eye damage associated with lasers.

LEDs 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.

LEDs also allow the light beam to spread out instead of being a pinpoint light beam. The wide-angle diffusion of the LED provides greater ease of application, since light emissions are thereby able to penetrate a broader surface area. 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 non-toxic, 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 within a few treatments, resulting in a reduction in the use of pain and anti-inflammatory medications.

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 in the United States has approved light therapy for the treatment of head and neck pain, as well as pain associated with CTS (Carpal Tunnel Syndrome).

The light wavelengths used in Photizo Light Therapy

Visible red light: Light that lie within the visible spectrum, from 400 nm* (violet) to 700 nm (red). At a wavelength of 660 nanometers, 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 700 nm to 2 000 nm. Infrared rays are not visible to the eye; they penetrate to a depth of about 30-40 mm (1.2″ to 1.4″), making them 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.

*:1 nanometer (nm) is equal to one billionth of a metre
