Green LED light source amazing medical effect
- Jul 24, 2017 -

At present, the State's attention and investment in health care and national health increase, making the demand for health lighting is increasing, and with the progress of technology and research and development, the relationship between light and health is increasingly being discovered, and a series of thematic studies are being carried out or deepened, such as light and non visual biological effects, light medicine, health light environment, etc., around the health lighting, more interdisciplinary interdisciplinary cooperation across the field. At the same time, LED lighting produced, but also to the lighting field of the original evaluation methods, systems bring challenges. 

The research of illumination is in-depth, and the relationship between light and health is more and more discovered by human beings. Dr. Mohab Ibrahim, of the University of Arizona, accidentally found that sitting under the tree during a headache seemed to have analgesic effects. Out of curiosity, he decided to do a simple experiment to test whether the green light really relieves chronic pain.

The team, led by Dr. Mohab Ibrahim, studied three experimental white mice with neuropathic pain. They placed the first group of mice in a transparent plastic container with green LED light strips that lasted eight hours a day for five days. The second group of mice was placed in a general indoor lighting environment, but the use of special contact lenses, only allow the green light through the mouse eyes. As for the third group of controls, the white wore opaque contact lenses and could not see any color of light.

The results showed that the first two groups could withstand a higher temperature and tactile stimulation than the mice in the control group, and no side effects were found in the process. And after the last light, the mice continued to maintain that effect for the next four days.

Scientists have tentatively concluded that this may be because the green light enhances the level of "endogenous opioid substance" (endogenous opioid) in mice. This substance can withstand pain and relieve inflammation in the nervous system. The findings were published in the February issue of the pain Journal of Pain.

At present, researchers are encouraging the initial results of a 10-week human clinical trial of 10 patients with fibromyalgia (fibromyalgia). Because of the remarkable analgesic effect, even two patients refused to return the green LED light source to the research team.

Although the study is still in its infancy, Dr. Mohab Ibrahim said the light created by green LED light has considerable potential to reduce specific chronic pain, which is safe, effective and affordable. He hopes to introduce green LED light therapy in the future, or with other methods to help many patients suffering from pain.
