Physiological Effect of Bhrāmarī prāṇāyāma on Various Systems of the Human Body: A Narrative Review

Introduction: Bhrāmarī prāṇāyāma is a classical yogic breathing technique characterized by slow nasal inhalation followed by prolonged exhalation accompanied by a humming sound. Traditionally described in yogic literature for its calming influence on the mind, Bhrāmarī prāṇāyāma has gained increasing scientific attention for its physiological and therapeutic effects.

Aim, Methodology: The present narrative review aims to compile and critically analyse available evidence regarding the effects of Bhrāmarī prāṇāyāma on different systems of the human body. Relevant literature was identified from classical yogic texts and contemporary scientific studies. 

Review: Evidence suggests that Bhrāmarī prāṇāyāma exerts a positive influence on the autonomic nervous system, cardiovascular and respiratory functions, neuroendocrine regulation, and psychological well-being. The practice appears to promote parasympathetic dominance, reduce stress responses, and improve overall physiological homeostasis. 

Conclusion: Bhrāmarī prāṇāyāma may therefore serve as a simple, safe, and cost-effective adjunctive intervention for stress-related and lifestyle disorders.
