Light therapy is being used as an effective alternative treatment for a variety of ailments with encouraging results. What makes light therapy so favorable is other modes of treatment involve surgery or drugs . With the latter two treatment methods, risks to the patient are higher.
For medical uses, doctors and researchers are using varying wavelengths of light. The types of light being used in these innovative therapies are; near infrared light, red light, blue light and ultraviolet light. Near infrared light with it’s long wavelengths can penetrate deeply
into human tissue.
Presently, near infrared light is being used at Children’s Hospital of Wisconsin to treat severe mucositis, oral sores that occur as a side effect of chemotherapy. Laboratory testing is being done for further applications such as reversing blindness and cutting the severity of a heart attack. Red light helps wounds heal more quickly and has an anti-inflammatory and antibacterial effect, acting as a natural skin care treatment.
Red light has been used to remove precancerous skin cells without scarring. When red light is used in combination with blue light, it has been effective in the treatment of severe acne. Also, when red light is used together with near infrared light, it induces collagen formation which
helps smooth out wrinkles in the skin. Blue light has been effective in the treatment of seasonal affective disorder.
A dose of blue light increases alertness and decreases insomnia. Exposure to blue light in the evening helps Alzheimer’s patients to sleep through the night. Ultraviolet light keeps bacteria and viruses from reproducing. It is used in water treatment plants. Studies are being done for it’s potential to sterilize air in office and retail buildings.
Light effects human tissue at the cellular level and can help the body and skin repair itself. Research is uncovering a host of ways in which light therapy can help us.
