New Green Light Therapy Promising For Fibromyalgia Relief


Researchers at the University of Arizona discovered a new, promising way to relieve chronic pain.

The investigators found that lab animals with neuropathic pain showed improvement after being bathed with green light-emitting diodes (LED), when compared with animals not bathed in green LED. The pain relief benefits continued for four days after final exposure, and no side effects of the light therapy were observed.

The animals were exposed to green LED either by housing them near green LED strips, or by fitting them with contact lenses that let the green wavelength of room light pass through.

“Chronic pain is a serious issue afflicting millions of people of all ages,” said lead study author Mohab Ibrahim, UA assistant professor of Anesthesiology and Pharmacology. “Opioids, while having many benefits for managing pain, come with serious side effects. We need safer, effective, and affordable approaches, used in conjunction with our current tools, to manage chronic pain. While the results of the green LED are still preliminary, it holds significant promise to manage some types of chronic pain.”

Though the pain-relieving attributes of green LED are apparent, scientists are unclear how it works. Early studies suggest green light increases circulating endogenous opioids, which could account for the pain-reducing effects. Study coauthor Todd Vanderah states that green LED therapy might alter levels of natural pain inhibiting substances in the body, and may decrease nervous system inflammation.

The researchers are currently conducting a green LED study using human participants suffering from fibromyalgia. They hope the therapy will relieve pain if used alone, or in tandem with other treatments such as low-dose analgesics, or physical therapy.
