Dutch researchers report that weather conditions including temperature, sunshine, and precipitation have no impact on fibromyalgia symptoms in female patients. Results published in Arthritis Care & Research, a journal of the American College of Rheumatology (ACR), suggest that individual patients may be sensitive to some changes in the weather.
Medical evidence shows that fibromyalgia affects 2% of the world population with a greater prevalence among women. In the U.S., the ACR estimates that five million people experience the widespread pain, unexplained fatigue, headaches, and sleep disturbances from this chronic pain syndrome. While the cause of fibromyalgia remains a mystery, studies suggest patients have increased sensitivity to a range of stimuli and up to 92% cite weather conditions exacerbate their symptoms.
"Many fibromyalgia patients report that certain weather conditions seem to aggravate their symptoms," explains first author, Ercolie Bossema, Ph.D. from Utrecht University in the Netherlands. "Previous research has investigated weather conditions and changes in fibromyalgia symptoms, but an association remains unclear."
To further explore the impact of weather on pain and fatigue in fibromyalgia, the team enrolled 333 female patients with this pain syndrome in the study. Participants had a mean age of 47 years and had a diagnosis of fibromyalgia for nearly 2 years. The patients completed questions regarding their pain and fatigue symptoms over a 28-day period. Researchers obtained air temperature, sunshine duration, precipitation, atmospheric pressure, and relative humidity from the Royal Netherlands Meteorological Institute.
Findings indicate that in 10% of analyses, weather variables showed a significant but small effect on pain or fatigue symptoms. In 20% of analyses, researchers found significant small differences between patients' responses to weather, suggesting pain and fatigue symptoms were diff
