Ultraviolet (UV) light has been used to purify and deodorize air, destroy bacteria and sterilize water. Objects that have been contaminated like bedding, room air, skin and surgical instruments have all reportedly been rapidly cleansed of bacteria and viruses using UV light. New scientific discoveries for UV light have included that in various intensities the wavelengths can also treat seasonal affective disorder (SAD), as well as various kinds of muscle and joint pain for certain body parts.
Photo Therapy Uses
Photo (therapeutic light) therapy, or "UVBI" has been determined to be very useful in pain management of medical conditions such as arthritis, Carpal Tunnel Syndrome, osteoarthritis, plantar fasciitis, fibro myalgia, tennis and golfers elbow, bone chips and spurs as well as leg, ankle, wrist, shoulder and back pain. UV light therapy has also promoted healing for various joint and muscle injuries. Light therapy has been used for sleep disorders and to increase energy. The Mayo Clinic has reported that various forms of light therapy, including blue light and diode laser, have also been effective as new acne treatments.
Light Therapy Devices
Numerous companies have developed light therapy machines in various types and sizes to suit a variety of uses. Some come with straps so that they may be easily applied to areas such as arms and knees. Some devices were created to handle specific types of pain associated with various ailments.
Pain Management
UV light therapy utilizes infrared light that emits diodes (LEDs) which direct a stream of warmth deep within muscle tissues. Circulation and blood flow, in turn, is increased to certain targeted areas for relief of joint and muscle pain, stiffness and aches.
NASA Study
UV light therapy technology has been researched by NASA in connection with skin problems, cancer, to grow plants and for pain relief. According to a NASA study, the usage of light therapy resulted in significant pain relief for pediatric patients that had bone-marrow transplants and were suffering from chemo and radiation treatment side effects, as reported by Dr. David Margolis, associate professor of pediatrics at the Medical College, with Dr. Whelan at Children's Hospital.
Cost
Light therapy devices are available at a variety of stores, both online and off and most can be purchased without providing a doctor's prescription. Many of the machines are lightweight and portable, ranging from $150 to $400.
