People With Fibromyalgia More Likely to Have Sleep Problems, Study Says
People with fibromyalgia have poor sleep quality and experience more sleep disturbances than people without the disorder, according to data from a new study. The study, “Comparison of sleep structure in patients with fibromyalgia and healthy controls,” was published in the journal Sleep and Breathing. More than 90% of patients with fibromyalgia report experiencing sleep problems, including difficulty falling asleep, frequent nighttime awakenings, and poor sleep quality. Most studies on sleep and fibromyalgia have focused on sleep quality, since the amount of sleep does not seem to vary between patients with the disease and healthy individuals. Even when patients sleep six to eight hours a night, they often wake up feeling fatigued, unrefreshed, stiff, and in pain. The relationship between pain and sleep disturbances is thought to be bidirectional — pain affects sleep, and, in turn, sleep problems exacerbate pain. Therefore, treating sleep disturbances in people with fibromyalgia may ease their pain. Polysomnography (PSG) is a sleep test that records brain waves, blood oxygen levels, heart rate, and breathing, as well as eye and leg movements to diagnose any underlying sleep disorders. Prior studies have reported differences in several PSG parameters between those with and without fibromyalgia. However, these findings have been inconsistent across studies. A group of researchers in Turkey set out to compare the sleep structure, using objective and subjective sl
