Effect of alternate nostril breathing exercises on cardiorespiratory function- a systematic review

Abstract

Introduction- Alternate nostril breathing has positively affected the cardio-respiratory system. This review aimed to compile information on the effects of alternate nostril breathing on cardiorespiratory function. Method– Databases such as PubMed, Medline, Scopus, Cochrane, and Google Scholar were systematically searched to review current evidence of randomized control trials (RCT) on alternate nostril breathing over the past two decades. Out of 89 articles, six were chosen for the final data extraction based on the inclusion and exclusion criteria. Results- All of the final included studies demonstrated a significant improvement in respiratory endurance and functioning and a high heart rate variability (HRV) that mostly has a parasympathetic effect. Conclusion- Alternate nostril breathing shows promising results in reducing stress, improving cardiovascular and respiratory function, and reducing complications of pulmonary problems in the future.
