The systematic review “Effects of Bhramari Pranayama on health” by Maheshkumar Kuppusamy and team provides a detailed look at the health benefits of Bhramari Pranayama (Bhr.P), a yoga breathing technique. The review compiles research up to May 2016 to give a full picture of the health advantages of Bhr.P.

Methodology and Review Criteria

The review used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (Prisma) guidelines. It included studies focusing on the health effects of Bhr.P, using various databases. The studies were chosen based on set criteria and were evaluated for quality and reliability using the Methodological Quality Rating Scale (MQRS) and Newcastle-Ottawa Scale (NOS).

Main Findings

The review found that Bhr.P has several physiological benefits. It can positively affect the cardiovascular system, EEG wave patterns, cognitive functions, and conditions like tinnitus. Bhr.P tends to increase parasympathetic activity, leading to a lower heart rate and blood pressure, better cognitive control, and reduced stress levels.

Study Design and Quality

The review noted that the methodological quality of the studies was generally low, with no randomized controlled trials (RCTs). This limits the strength of the conclusions.

Future Research Directions

The review highlights the need for more comprehensive, well-designed RCTs to confirm the effects of Bhr.P. It suggests studying its impact on the respiratory and autonomic systems, stress markers, and emotional well-being.

Conclusions and Practical Uses

The review suggests that Bhramari Pranayama, which combines slow breathing and humming, could have significant health benefits. However, more rigorous research is needed to fully understand its effectiveness and role in health and wellness practices.
