Fibromyalgia Successfully Treated With Light Box Therapy (Study Results)



Bright Light Improves Function, Pain in Fibromyalgia


There’s new way for fibromyalgia sufferers to improve function and ease pain sensitivity. 

According to a recent pilot study, bright light treatment is an effective complimentary treatment which shifts sleep patterns in a a way that helps relieve fibromyalgia symptoms by improving function and reducing pain.

Helen J. Burgess, PhD, director, Biological Rhythms Research Laboratory and professor, Department of Behavioral Sciences, Rush University Medical Center in Chicago, Illinois, presented the study in Boston at the 31st Annual Meeting of the Associated Professional Sleep Societies.


Testing Light Box Therapy for Fibromyalgia


Fibromyalgia patients were assigned 6 days of self-administered light treatment.


Dr Burgess and her colleagues tested the effect of bright-light treatment on function and pain sensitivity in 10 women meeting 2010 criteria for fibromyalgia from the American College of Rheumatology.

The women slept at home, keeping their usual sleep schedule for 1 week, followed by an overnight session in the sleep lab.

During the overnight session, the researchers assessed baseline function (Fibromyalgia Impact Questionnaire [FIQ]), pain sensitivity (heat threshold and tolerance), and circadian timing (dim-light melatonin onset). 

The following morning, the women were randomly assigned to 6 days of a self-administered home either morning or evening light treatment, using a light box 1 hour per day.

Afterward, function, pain sensitivity, and circadian timing were reassessed.


The women with fibromyalgia used light boxes for 1 hour each day.


Study Results



On average, the women completed 84% of the scheduled light treatments. No side effects were reported.

Both morning and evening light treatments led to improvements in function and pain sensitivity, but only morning light treatment led to a clinically meaningful improvement in function (>14% reduction in FIQ) and heat pain threshold (P < .05).


Morning light box treatments improved function by 14% and decreased pain threshold by 5%.



Results Equal to Cognitive Behavioral Therapy


Dr Burgess noted that the improvement was about equal to that seen after cognitive-behavioral therapy and about half of that seen after weeks of intense exercise therapy. 

The study also found that phase advances in circadian timing were associated with a significant increase in pain tolerance.


Morning light box treatment improved fibromyalgia pain tolerance by 67%.


Clinically Significant Implications


Light therapy is a potentially feasible add-on therapy for fibromyalgia.


The study authors concluded that:

“Morning bright light treatment should be further explored as a potentially feasible, acceptable and effective adjunctive [add-on] treatment for fibromyalgia.

The improvement in function was similar to that seen after psychotherapy, and about half of the improvement seen after months of exercise training.”


Improvements using a light box were similar to that seen after psychotherapy, and half of the improvement gained from months of exercise training.


A “Noteworthy” Study


Shelby Harris, PsyD, director, Behavioral Sleep Medicine, Sleep-Wake Disorders Center, Montefiore Health System, New York City, says this is a “very noteworthy and novel study since, in terms of helping sleep and fibromyalgia, the researched sleep treatments in this population — that we currently have on hand — are cognitive-behavior therapy for insomnia and medication interventions.”

“This study utilized a simple, quick method (light therapy) to help patients shift sleep patterns in a way that appears to help their fibromyalgia symptoms,” says Dr Harris.

“Patients with fibromyalgia typically suffer from difficulties falling asleep and staying asleep,” she said, “and this study noted that early-morning light exposure helped to advance their sleep timing, helping them to fall asleep earlier.”

“It is very possible that earlier sleep times, with less tossing and turning in bed throughout the night, can lead to more alertness in the morning, pain tolerance, helping to decrease pain and increase overall functioning. However, this was a small study and one that needs more research behind it,” added Dr Harris.


Morning light treatment led to significant improvement.


She also noted that some patients are “not ideal candidates for light boxes due to eye problems, and it would be interesting to see whether similar results would be found using natural outdoor light. This is worth studying further because a simple technique may make a big impact on the lives of those with chronic pain problems. More research is needed in this area,” said Dr Harris.

Kevin Fleming, MD, medical director of the Fibromyalgia and Chronic Fatigue Clinic at Mayo Clinic in Rochester, Minnesota, also thinks the study is noteworthy.

“Although a small study (just 10 patients) and only 1 week long, it is very suggestive of being useful because it fits with at least one physiology issue known to contribute to FM [fibromyalgia] — bad sleep. Light therapy may address that portion,” he said. 

Impaired sleep is known to be common in FM and likely contributes to pain (sleep deprivation makes people have widespread discomfort like FM),” Dr Fleming explained. “Why this is so is unclear; what sleep does for our muscles and brain is uncertain. But lacking good sleep contributes to pain, so it is reasonable to focus on sleep in treating FM.”

“The sleep clock (circadian rhythm) is set at least in part by your exposure to bright light, such as sunlight. Exposure to bright light or light therapy can remedy that part of the sleep disorder,” he noted.


Light Therapy Also Effective For Depression


Light therapy has been proven to relieve depression.


Morning light treatment has already been shown to reduce depression, which can lead to diminished pain and improvement in people’s ability to cope and function with pain.

A 2016 placebo-controlled clinical trial published in the Journal of the American Medical Association Psychiatry found that:


“Bright light treatment, both as monotherapy and in combination with fluoxetine, was efficacious and well tolerated in the treatment of adults with nonseasonal MDD [major depressive disorder].”


The research was the first first placebo-controlled trial that shows that light therapy is an effective treatment for depression that is not brought on by seasonal affective disorder.

“These results are very exciting because light box therapy is inexpensive, easy to access and use, and comes with few side effects,” said Dr. Raymond Lam, a UBC professor and psychiatrist at the Djavad Mowafaghian Centre for Brain Health, a partnership between UBC and Vancouver Coastal Health.

“Patients can easily use light therapy along with other treatments such as antidepressants and psychotherapy.”

Lam and his colleagues followed 122 patients and evaluated whether light therapy improved the mood of patients when it was used both with and without the commonly prescribed antidepressant fluoxetine [Prozac].


Light therapy involved 30 minutes of exposure to a light box soon after waking up every day for eight weeks.


Some study participants were given placebo pills and placebo devices instead of the real therapies. The researchers found that light therapy helped many patients and provided the most benefit to those who were also taking antidepressants.


Future Fibromyalgia Studies


Dr Fleming said light therapy for fibromyalgia is worth continued study. 

“There’d be no way to do a randomized trial I can think of, but size could be increased and compared to usual FM care for 12 months,” he said.

But before those studies are completed, “it is really low risk for FM patients to trial [light therapy] in the morning,” he said.
