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.

Physiological changes during the menstrual cycle in women with primary dysmenorrhea may affect their respiratory system, so this study aimed to examine various respiratory parameters in three phases of the menstrual cycle in these women. Materials and Methods:This study was conducted on 15 women with dysmenorrhea aged 18-25 years. The respiratory parameters were measured using a capnograph during the menstrual phase (MP; on days 3 or 4), follicular phase (FP; on days 10 or 11), and luteal phase (LP; on days 20 or 21). Results:The results of this study showed a significant difference in end-tidal CO 2 pressure in the follicular and luteal phase with that in the menstrual phase (P<0.01). Also, the respiration rate and oxygen saturation showed a significant difference in different phases of menstruation (P<0.01). Conclusion:The results of this study indicated that respiratory indices differ in various phases of the menstrual cycle in women with primary dysmenorrhea, which seems to be due to pain during the menstrual cycle and increased progesterone levels in the luteal phase.
