Sleep dysfunction is considered an integral feature of fibromyalgia. About 70% of patients recognize a connection between poor sleep and increased pain, along with feeling unrefreshed, fatigued, and emotionally distressed. [45, 46] Several studies have linked abnormal sleep with these symptoms. Sleep studies have shown that patients with fibromyalgia have disordered sleep physiology.

Sleep is not a state of massive system shutdown. On the contrary, the brain is active during sleep, constantly communicating with the body. Many neurohormones, antibodies, and other molecules are synthesized during sleep; therefore, when sleep is disrupted, biochemical abnormalities can occur, leading to multisystem disturbances.
