PURPOSE: The purpose of this study was to assess the efficacy of breathing exercises alongside traditional therapy on respiratory indexes and the level of anxiety of generalized anxiety disorder patients. PARTICIPANTS AND METHODS: Forty-one patients were assigned a study group undergoing medication and routine counselling plus breathing exercises (EXS), and a control group received medication and routine counselling only (Non-EXS). Every two weeks, patients are called (weeks 2, 4, 6, and 8) to monitor their schedule adherence. RESULTS: This study's results showed FEV1/FVC ratio significantly increased in the EXS group in the second study follow-up period after two months. Anxiety, FVC, FEV1, Etco2, respiration, and pulse rate over time have tended towards desirable results in the exercise group than control groups, especially after two months, but significant differences not seen. CONCLUSION: This study's findings indicated that breathing exercises could improve generalized anxiety disorder's pharmacotherapy and psychotherapy. Our data bring up this hypothesis that longer follow up, increasing breathing period, and more exercising is associated with higher outcome.
