Out of 5,000 red (and blue, infrared, green and yellow) light studies in the past 50 years, the vast majority support light therapy as a reliable healing modality. Red light therapy can heal so many problems because it stimulates the body to make energy. Rather than acting on the wrinkles or acne, or pain, it stimulates the cells to make the energy required for the body to heal itself. Cold Laser or Low Level Light Therapy (LLLT) came out of laser medicine when researchers realized that “cold” light heals. You don’t need a hot column of laser light to get the healing effects. You just need the right wavelength (color) and irradiance (power) to stimulate the body into a healing state. Our bodies absorb light in photoreceptors. When we absorb enough light of the right color, the body kicks off a cascade of healing events. For about the last 20 years, researchers have performed over 5,000 studies to test new light therapy ideas. They tested low energy laser beams, and low energy light emitting diodes (LEDs). Repeatedly they found that low energy lasers and LEDs triggered a healing response. These studies justified investment in home-use LED light products. Red light therapy is the most popular, and usually includes both red and infrared light. Home devices emitting blue, green or yellow light are now becoming popular, as those colors have specific healing abilities as well. #photobiomodulation #redlighttherapy #lighttherapy #coldlaser #lowlevellighttherapy #lllt
