Light surrounds us every day, it’s so easy to take for granted. Yet, what we perceive as light is actually a form of energy that behaves both as a wave and a stream of particles called photons. Light streams photons to our bodies—tiny packets of energy with a number of beneficial effects such as restoring balance to the system.
What is light therapy?
Light therapy has been shown in over 50 years of independent research worldwide to deliver powerful benefits to living tissues and organisms. Visible red, blue and “invisible” infrared light have been shown to effect at least 24 positive changes at the cellular level. According to some clinical studies, light therapy has been shown to increase energy, stimulate collagen, ATP and nitric oxide; reduce pain and inflammation; and reduce stress.
These studies also have shown that light energy causes biologic effects based on the knowledge that specific proteins absorb different wavelengths. Light Emitting Diodes (LEDs) are a form of light energy that is a relatively recent outgrowth from the laser industry. LEDs are similar to lasers in that they have the same effects but differ in the way that the light energy is delivered. LED disperses light (red, blue or infrared) over a greater surface area; this tends to result in shorter session times for a given area. LED light is a safe, noninvasive way to ‘enlighten’ cells.
Who uses LED light therapy?
There are volumes of scientific studies available. The following is just a sample list of institutions that have conducted clinical studies on the effectiveness of LED Light Therapy:
- National Institute of Health
- Mayo Clinic, Jeffrey Basford, MD
- Stanford University, Kendric C. Smith
- Harvard Medical School
- NASA, Dr. Harry T. Whelan
- Marshall Space Flight Center
- Yale Medical School
