Fibromyalgia is a condition that can contribute to widespread musculoskeletal pain and temperature sensitivity, which in turn may cause poor sleep. People with fibromyalgia may experience other sleep problems such as disruptive sleep, lack of restorative sleep, and/or insomnia. The condition can also lead to sleep apnea and restless leg syndrome. While you should consult a doctor about treating fibromyalgia, a supportive, comfortable mattress can promote quality sleep regardless of underlying conditions.
