Effect of Mahamantra Chanting on Autonomic and Cognitive Functions- An Interventional Study

Abstract

Introduction: Stress is a major health issue which leads to several potential negative health and well-being outcomes. Early interventions like yoga, meditation and music can reduce stress induced morbidity and mortality. “Chanting is considered as one form of bakthi yoga which improves concentration and memory, relieves stress and depression and helps one to get rid of anxiety” says Upanishad. Aim: To find the effect of Mahamantra chanting in reducing stress among women nursing professionals. Materials and Methods: In this study, subjects (n=30) with moderate to severe stress levels (PSS≥14) were recruited and grouped into mahamantra (n=15) and control groups (n=15). Physiological parameters like Heart Rate Variability (HRV), serum cortisol levels and cognitive functions using Auditory (ART) and Visual Reaction Time (VRT) were measured. Mahamantra intervention was given (n=15) to one group while the control group (n=15) did not participate in the mahamantra chanting. Results: This study showed significant increase in parasympathetic tone (LF/HF ratio) (p<0.05), shortened ART (p=0.05), VRT (p=0.01) and significant decreased serum cortisol levels (p=0.05) among subjects who underwent Mahamantra intervention. Conclusion: The study results highlight the beneficial effects of simple mahamantra chanting intervention in reducing stress among nursing professionals with moderate to severe stress.
