“More and more evidence is emerging that shows the benefits of these healing waves of light, without surgery or medication, and the therapy can be done at home,” Flagstaff’s Michelle Boyer, PA-C, certified light therapist, spine care specialist and owner of Your Shining Life, LLC, said.

“It is amazing what just 20 minutes two to four times per week can do for the body. The changes on the cellular level helps the body heal itself from the inside out.”

Polychromatic Light Therapy, or PLT, (medically called photobiomodulation) uses pulsating, low-level (LED), specific wavelengths (colored) of light that can penetrate into the body to promote healing and decrease pain. PLT has been known for more than 40 years but is gaining more widespread acceptance as research provides answers as to how and why this deeply penetrating light benefits the body.

(PLT should not be confused with light therapy boxes that use full-spectrum lights to treat conditions such as Seasonal Affective Disorder and depression; or high-power or low-level laser light therapy, which uses amplified light on a targeted area.)

How PLT works:

Our cells require light, such as sunlight, for optimal function and each cell has photo-acceptors to receive light. Direct, intentional application of light triggers the cells to kick into high gear.

PLT uses a specific combination of pulsating blue, red and near-infrared lights that are able to penetrate into the body.

For example, PLT blue light penetrates about two to three millimeters; PLT red light penetrates about eight to 10 millimeters; and PLT near-infrared light can penetrate from 20 to 100 millimeters, reaching deep into the body. These waves of light are absorbed into the cells to assist in the production of ATP, the energy the body needs for cell repair and regeneration.

The light also triggers the cells to release nitric oxide, which causes blood vessels to dilate and increase circulation throughout the body. The increase in the production of ATP and circulation stimulates the body’s healing process and decreases pain in the area the lights are applied and other areas of the body.

PLT is known to:

• Increase oxygenation in the blood

• Reduce pain

• Decrease inflammation and edema

• Promote muscle relaxation and reduce tenderness

• Accelerate natural healing processes

• Rejuvenate body tissues

Some medical conditions that benefit from PLT include:

• Joint pain in the neck, back, fingers, elbow, knee, wrist

• Swelling and inflammation from illness or injury

• Lymphedema

• Brain injuries

• Bone fractures

• Bruises

• Burns

• Non-healing wounds

• Peripheral neuropathy

• Tight/sore muscles

• Mood disorders

• Skin conditions

Currently, Medicare and most insurance companies do not cover this FDA Class II medical device. Fortunately, it is considered durable medical equipment so the cost can often be applied to out-of-pocket medical expenses and health saving plans can be used to purchase and/or rent the at-home technology. The technology is sold via FDA-approved companies and is not available in stores. Boyer helps people choose the correct products and provides training and support on how to properly use the technology to gain the most benefits.
