Zusammenfassung: | Breathing exercises have been reported to have positive physiological effects on the body. The incidence of hypertension has become a major risk factor for cardiac complications leading to higher morbidity and mortality. Our aim was to conduct a systematic review and meta-analysis to study the effect of breathing exercises on blood pressure (BP) and heart rate (HR).
A systematic review and meta-analysis analyzing randomized clinical trials (RCTs) about the effect of breathing exercises on blood pressure was conducted (PROSPERO Registration ID: CRD42022316413). PubMed, ScienceDirect, WebofScience, and Cochrane Library databases were screened for RCTs from January 2017 to September 2022. The main search terms included “breathing exercise”, “Pranayam”, “Bhramari”, “alternate nostril breathing”, “deep breathing”, “slow breathing”, “hypertension”, and “high blood pressure”. The primary outcome was the value of the systolic blood pressure and diastolic blood pressure after the intervention. The effect on heart rate was also analyzed as a secondary outcome.
A total of 15 studies were included in the meta-analysis. Breathing exercises have a modest but significant effect on decreasing systolic blood pressure (−7.06 [-10.20, −3.92], P = |
