Red light therapy has shown great benefits in natural health intervention. Many industries have welcomed light therapy for the versatility of this treatment. From cold sores to medical depression, light therapy has shown exceptional promise.
Most of our health problems occur due to damage to the body cells.
Light therapy energizes our body from a cellular level. Therefore, our cells can repair and replicate themselves. It allows us to keep an overall healthy body.
Cold sore is a viral condition initiating itching, burning, or tingling sensation around your mouth. Red light therapy has proven to be helpful in reducing the lasting period of cold sores.
In this article, we are going to discuss how to treat cold sores with light therapy. Stay tuned.
What is Red Light Therapy?
Light therapy is a modern means of therapy using different light wavelengths. Normally, blue, green, red, and near-infrared wavelengths are used in this therapy.
Red light and near-infrared light have the highest wavelength among visible light. It penetrates deeper into the skin and induces a healing effect. Also, it helps repair your inner cells and restores your circadian rhythm.
In red light therapy, 600 to 680 nm wavelengths of light. In near-infrared therapy, 750 to 850 nm of light wavelength are used.
Red light therapy boosts collagen production in the skin tissue. Also, it helps with proper circulation in the body. Therefore, blood and oxygen can easily rotate around the body, reduce inflammation and induce healing effects.
LED light bulbs are used in red light therapy. These bulbs emit the exact wavelength of visible light. Thus, it contains no harmful UV rays, unlike natural sunlight.
How Light Therapy Works on Cold Sores?
All light doesn’t work equally on the body. Also, natural sunlight or UV radiation can be pretty harmful to the skin and health. Therefore, you will need to find the spectrum of the light that can heal the body without causing harm.
Red and near-infrared wavelengths are most suitable in this manner. When used together, these two wavelengths of light can accelerate the healing process.
Visible red light has the biggest wavelength among other visible colored light. Thus, it can travel deeper into the skin. Therefore, light therapy can energize the cells deeper in the skin and tissue cells.
A 2009 research concluded that 69 patients had shown significant improvement after one therapy session. Another long-term, large-scale study has found a significant time-span between flare-ups.
When light is emitted upon the skin, the cells absorb energy from the light. The energized cells can shield themselves from damage. Also, they gain the ability to repair and replicate themselves. It can work as a cure for cold sores.
Preventing cold sores from occurring is not an option yet. However, it is possible to reduce inflammation, infection and distance the time between each flare-up.
Light therapy can certainly help in this manner. However, you will need to maintain some precautionary measures.
