Researchers from the Indian Institute of Technology Mandi have discovered that listening to the Indian classical music raga Bhairavi in an immersive virtual reality (VR) environment can significantly reduce stress, anxiety, and depression. This groundbreaking study, published in the Scientific Reports journal, offers a promising new approach to mental health treatment that combines the ancient healing traditions of Indian music with cutting-edge VR technology.
Addressing India’s Mental Health Crisis
India is facing a growing mental health crisis, with an estimated 150 million people struggling with conditions like stress, anxiety, and depression. The country’s healthcare infrastructure has struggled to keep up, making innovative and accessible treatment options a pressing need. This study by researchers at the Indian Institute of Technology Mandi offers a potential solution that could revolutionize mental healthcare in India and beyond.
The Power of Raga Bhairavi
The foundation of Indian classical music is the raga, a melodic framework that evokes specific emotional responses. The researchers focused on the raga Bhairavi, which is considered a “complete” raga and is traditionally associated with calmness and introspection. By having participants listen to Bhairavi in an immersive VR environment, the researchers aimed to harness the therapeutic potential of this ancient musical tradition.
Measuring Psychological and Physiological Markers
To assess the impact of the Bhairavi VR intervention, the researchers used a combination of subjective and objective measures. Participants completed the Depression, Anxiety, and Stress Scale (DASS-21) before and after the six-day intervention, allowing the researchers to track changes in psychological well-being. Additionally, the researchers monitored the participants’ heart rate variability (HRV), a physiological marker that reflects the balance between the sympathetic and parasympathetic nervous systems.

Significant Improvements in Mental Well-being
The results of the study were remarkable. After just six days of listening to Bhairavi in the VR environment, participants in the intervention group showed significant reductions in all three DASS-21 subscales: stress, anxiety, and depression. In contrast, the control group, which did not receive the VR-based raga intervention, did not exhibit any significant changes in their psychological well-being.
Physiological Evidence of Relaxation
The objective HRV data provided further evidence of the intervention’s efficacy. The VR-raga group demonstrated enhanced autonomic balance, indicating a reduction in physiological stress and an increase in parasympathetic (relaxation) activity. Parameters like standard deviation of heart rate, heart rate variability triangular index, and low-frequency to high-frequency ratio all showed significant improvements in the intervention group compared to the control group.
Unlocking the Therapeutic Potential of VR-based Music Intervention
This study’s findings highlight the immense potential of combining virtual reality and Indian classical music for mental health treatment. By creating an immersive, captivating environment, the researchers were able to amplify the therapeutic benefits of the Bhairavi raga, leading to measurable improvements in both psychological and physiological markers of stress and relaxation.
Implications and Future Directions
The implications of this research extend beyond the Indian context. The VR-based music intervention could be a game-changer in the field of mental healthcare, offering a non-invasive, engaging, and accessible approach to managing conditions like stress, anxiety, and depression. The researchers are now exploring the long-term effects of this intervention and its potential applications in clinical settings, as well as investigating the use of other Indian classical music ragas for their therapeutic properties.
This groundbreaking study demonstrates the power of integrating ancient cultural traditions with cutting-edge technology to address the pressing mental health challenges of our time. By harnessing the emotional resonance of Indian classical music and the immersive capabilities of virtual reality, the researchers have paved the way for a new era of holistic, technology-driven mental health solutions.
