How Yellow Light Therapy Works
Inspired by pioneers like Roland T. Hunt and his 1971 book, “Seven Keys to Color Healing,” the patent-pending Visum Light encompasses the entire spectrum of light therapy — from contemporary science to metaphysical insights regarding color and the body.
This allows for a far more forward-thinking approach to handheld light therapy devices. As others become outdated and obsolete as new scientific evidence is uncovered, the Visum Light’s polychromatic design ensures it can adapt to new therapies and applications — making it the most versatile tool in your healthcare toolbox.
What is Polychromatic Light Therapy?
Also known as PLT, polychromatic light therapy involves the application of more than one color. Different combinations of wavelengths (colors) used simultaneously can provide synergistic effects — additional health benefits — in the same approximate amount of time as a single color.
Unlike most other light therapy devices, the Visum Light combines the three primary colors — red, blue, and green — to create additive colors. Red and blue light make magenta, red and green light make yellow, and green and blue light give us cyan (also known as turquoise).
By using additive colors, the body receives both the benefit of each individual color as well as the combined color the eye sees. Light therapy colors in the Visum Light each have their own healing properties and can be used independently or combined with another. What’s more, all colors can add near-infrared (NIR) light, allowing for deeper penetration and other benefits.
The most exciting aspect of polychromatic light therapy is that more research is needed to fully understand its benefits. By combining pioneering Color Healing theory with extrapolations on what we know thus far about primary color light therapy — along with established evidence like Yellow’s photorejuvenation capacity — we have a clear theoretical view of what future polychromatic light therapy will look like. And the Visum Light will be ready, with the versatility needed to provide exciting new treatments.
Yellow Light Therapy
What we know so far about yellow light is pretty remarkable — much like red and NIR, it makes an effective wound-healing treatment, including scars and burns. Yet it seems to be more effective under certain conditions, which is pretty intriguing. It may have something to do with yellow light’s collagen expression properties, which show great potential as an effective new skin photorejuvenation therapy.
Regarding Color Healing theory, yellow is believed to support the function of various organs, including the stomach, liver and intestines. It’s also believed to stimulate the thymus gland. Yellow light is said to ease digestive issues, aid in metabolism, enzyme activation of the liver, and boosting the immune system via the thymus gland.
