Light Therapy for Fibromyalgia

(Light Bulb Trial)

This trial explores whether different types of light exposure can reduce pain for individuals with fibromyalgia, a condition causing widespread pain and fatigue. Participants will try two types of light treatments—Equal-Energy White Light and S-Cone Stimulating Chromatic Light—each for one week, to assess their effects on pain and sensitivity. This trial suits those who have experienced fibromyalgia or ongoing pain in multiple body areas for at least three months. Participants must be willing to use special light bulbs in their homes for two hours daily. As an unphased trial, this study offers a unique opportunity to explore innovative treatments and contribute to advancing fibromyalgia research.

Research has shown that both types of light therapy being tested—equal-energy white light and S-cone stimulating chromatic light—are generally safe.

For equal-energy white light, studies have found that low-level light therapy (LLLT) is well tolerated and has no known side effects when used correctly. However, it is not recommended for pregnant women.

Regarding S-cone stimulating chromatic light, past studies, especially those involving green light exposure (similar to S-cone stimulation), reported no safety concerns. This suggests that the treatment is safe for regular use.

Researchers are excited about using light therapy for fibromyalgia because it offers a non-invasive alternative to standard treatments like medications and physical therapy. Unlike traditional methods, which often involve drugs targeting pain or inflammation, this approach utilizes specific types of light—equal-energy white light and S-cone stimulating chromatic light—to potentially influence sensory processing and pain perception. This innovative method could provide relief without the side effects associated with medications, and it works quickly, potentially showing results in just a week of daily 2-hour sessions.

This trial will compare two types of light therapy for fibromyalgia: Equal-Energy White Light and S-Cone Stimulating Chromatic Light. Research has shown that light therapy can reduce pain in people with fibromyalgia. One study found that bright light treatments improved pain sensitivity and overall functioning. Another study demonstrated that whole-body light therapy reduced pain and enhanced quality of life. Specifically, colored light might improve pain and sleep quality. This therapy may work by influencing nerve cell function and inflammation management in the body. These findings offer hope that various light exposures can help manage fibromyalgia symptoms.⁶⁷⁸⁹¹⁰
