Effects of Box Breathing Exercise in Patients With Fibromyalgia

Fibromyalgia is a chronic condition that can cause widespread pain, sleep problems, fatigue, gastrointestinal symptoms, and reduced comfort. This study will evaluate whether box breathing exercise improves sleep quality, pain, gastrointestinal symptoms, and comfort in patients with fibromyalgia. A total of 60 participants will be randomly assigned to either an intervention group or a control group. Participants in the intervention group will continue their routine treatment and perform box breathing exercises for 10 minutes twice daily for 30 days. Participants in the control group will continue their routine treatment without receiving the breathing exercise. Sleep quality, pain, gastrointestinal symptoms, and comfort will be assessed at the beginning and at the end of the 30-day study period
