New breakthrough! US research and development of green LED light source can relieve pain

Modern people have a lot of stress, which leads to chronic pain. Many people may have to rely on painkillers, but the latest study from the University of Arizona found that illuminating green LED light sources can help relieve pain, and for future patients with chronic pain. It will be a great gospel.

Dr. Mohab Ibrahim of the University of Arizona unexpectedly found that sitting under a green tree during a headache seemed to have an analgesic effect. Out of curiosity, he decided to do a simple experiment to test whether green light can really alleviate chronic pain.

A team led by Dr. Mohab Ibrahim studied three groups of experimental white mice with neuropathic pain. They placed the first group of mice in a clear plastic container with green LED strips and continued to light for eight hours a day for five days. The second group of mice were placed in a general indoor lighting environment, but with special contact lenses, only green light was allowed to pass through the eyes of the mouse. White rats in the third group of control groups were wearing opaque contact lenses and could not see any color of light.

The results of the experiment showed that the former two groups were able to withstand stronger temperature and tactile stimuli than the white mice in the control group, and no side effects were found in the process. And after the last light, the mouse continued to maintain this effect for the next four days.

Scientists initially determined that this may be because green light increased the level of "endogenous opioids" in mice. This substance protects against pain and relieves the nervous system's inflammatory response. The results of the study have been published in the February issue of Pain.

Currently, the researchers are conducting a 10-week human clinical trial of 10 patients with fibromyalgia, and the initial results are encouraging. Because the analgesic effect was significant, even two patients refused to return the green LED light source used in the trial to the research team.

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