Beyond Relaxation: Can the Ancient Notes of Raag Malkauns Offer a Modern Path to Heart Health in Aging? 

Subtitle: A new physiological study from India explores the measurable impact of instrumental Indian classical music on the blood pressure of healthy elderly individuals, opening a window into non-pharmacological wellness. 

For centuries, the ethereal sound of a flute playing a slow, meditative Raag Malkauns at dusk has been a cornerstone of Indian cultural and spiritual life. It’s a sound instinctively associated with calm, introspection, and a quieting of the mind. But can this ancient musical tradition do more than just soothe the soul? Can its notes tangibly alter our physiology, specifically the cardiovascular health of our aging population? 

A compelling new study, published in Cureus in February 2026 by a team of researchers from Government Medical College, Datia, suggests the answer may be yes. Titled “Effect of Instrumental Indian Classical Music on Blood Pressure, Body Surface Temperature, and Oxygen Saturation Among Healthy Elderly Individuals,” the research offers a fascinating, data-driven glimpse into the intersection of art, culture, and physiological science. It moves beyond the generic notion of “relaxing music” to examine the specific effects of a structured Indian classical raga on the bodies of healthy older adults. 

The Silent Epidemic of Aging and Autonomic Imbalance 

As we age, our bodies undergo a subtle but significant shift in their automatic regulatory systems. The autonomic nervous system (ANS), which controls involuntary functions like heart rate, digestion, and blood pressure, gradually loses its flexibility. This process, known as autonomic dysregulation, is often characterized by a decline in parasympathetic tone—the “rest and digest” system—and a relative dominance of the sympathetic nervous system—the “fight or flight” response. This imbalance is a key contributor to the rising blood pressure and increased cardiovascular vulnerability seen in the elderly. 

While pharmaceutical interventions are often necessary, the search for safe, accessible, and non-pharmacological strategies to support cardiovascular health is more critical than ever. It’s in this context that the Datia study, led by researchers Palak Shilpi, Mahima Pareek, and their colleagues, becomes particularly relevant. They didn’t just ask if music relaxes people; they asked if a specific type of Indian classical music could physiologically counteract the autonomic trends of aging. 

The Study: A Deep Dive into the Data of Serenity 

The research team recruited 96 healthy participants aged 60 and above from the Datia district. To ensure the purity of their physiological data, they meticulously controlled for potential confounders. Participants were non-smokers, non-alcohol consumers, and had no significant auditory or cognitive impairments. They were asked to avoid caffeine and vigorous activity beforehand, and all measurements were taken in a quiet, temperature-controlled room to minimize environmental influence. 

The intervention was a 15-minute session of flute-based instrumental Raag Malkauns, delivered through noise-cancelling headphones at a comfortable volume. Raag Malkauns, with its pentatonic scale and use of komal (flat) notes, is traditionally associated with a serious, meditative, and calming mood, making it an ideal candidate for this type of therapeutic exploration. 

The researchers then tracked four key physiological parameters at four distinct time points: before the music (baseline), during the session, immediately after, and five minutes post-intervention. 

• Systolic and Diastolic Blood Pressure (SBP & DBP) 

• Surface Body Temperature (ST) 

• Peripheral Oxygen Saturation (SpO₂) 

The Harmony of Heart and Sound: What They Found 

The results, published in the February 21, 2026 edition of Cureus, paint a clear and encouraging picture. The most dramatic finding was a statistically significant reduction in both systolic and diastolic blood pressure. 

On average, participants experienced a drop of about 2.5 mmHg in both SBP and DBP. This reduction was not just a fleeting moment; pairwise comparisons showed that blood pressure values were significantly lower during the intervention, immediately after, and even five minutes post-intervention compared to the baseline. This indicates a sustained, albeit short-term, physiological calming effect. The effect was consistent across both male and female participants, suggesting the benefit is universal regardless of gender. 

“The consistent and sustained reductions in blood pressure observed across multiple time points indirectly support autonomic involvement,” the authors note, suggesting that the music likely encouraged a shift from sympathetic (stress) to parasympathetic (relaxation) dominance. 

Interestingly, the other two parameters told a different story. Oxygen saturation (SpO₂) remained remarkably stable throughout the entire process. While statistical analysis showed some variation, the actual numerical changes were clinically negligible and stayed within the healthy, normal range. This is a crucial safety finding, reinforcing that this type of intervention does not compromise respiratory function. 

Surface body temperature showed only a minimal decrease. The researchers posit that this slight dip, coupled with the negative correlation found between blood pressure changes and temperature changes, could hint at peripheral vasodilation—a subtle widening of blood vessels near the skin’s surface—which is another sign of reduced sympathetic tone and a state of relaxation. 

Why This Matters: From Anecdote to Evidence 

For generations, the calming effects of Indian classical music have been accepted as a matter of cultural wisdom. This study is significant because it begins to translate that wisdom into the language of evidence-based medicine. It’s a crucial step in validating a traditional practice with modern scientific rigor. 

The choice of Raag Malkauns is particularly insightful. The researchers were careful to distinguish its effects from other musical forms. They cite recent neurophysiological evidence showing that not all classical music is created equal; some structures with a higher ratio of minor notes might even increase stress. In contrast, the slow tempo and meditative, grounding structure of Raag Malkauns appear to be perfectly suited for fostering physiological calm. This highlights a critical point for future therapeutic applications: the “prescription” of music may need to be as specific as the prescription of a drug, with the right “raga” chosen for the desired effect. 

Dr. Koelsch and Dr. Jäncke, in a 2015 European Heart Journal paper referenced by the study, noted that “music and the heart” are intimately connected. This new research from Datia provides a practical, real-world example of that connection, demonstrating how a culturally-relevant auditory stimulus can act as a gentle, non-invasive modulator of cardiovascular function. 

The Limitations and the Unanswered Questions 

As with any pioneering research, this study raises as many questions as it answers, and the authors are transparent about its limitations. The most significant is the absence of a separate control group. While the participants served as their own controls (with baseline measurements acting as the point of comparison), this design can’t fully rule out a “placebo effect” or the possibility that any period of quiet, focused rest might produce similar results. Future studies with a control group listening to silence or a different genre of music are essential. 

Furthermore, the study measured the effects of a single, 15-minute session. We don’t yet know if these benefits accumulate over time. Would daily listening to Raag Malkauns lead to a sustained, clinically meaningful reduction in baseline blood pressure? This is the crucial next question. 

Finally, the researchers did not measure direct autonomic indicators like heart rate variability (HRV) , which is considered a gold-standard metric for assessing the balance between the sympathetic and parasympathetic nervous systems. Including HRV analysis in future research would provide a much deeper understanding of the mechanism by which the music exerts its effect. 

A Future Tuned to Wellness 

Despite these limitations, the “Datia District Study” is a valuable and promising contribution to the field of music therapy and geriatric care. It provides a robust foundation for future, more elaborate research. The implications are broad and exciting. Imagine a future where: 

• Community health programs for the elderly in India and beyond incorporate listening sessions of specific ragas as a low-cost, scalable intervention for stress management and cardiovascular support. 

• Geriatric care facilities use personalized “music playlists” based on classical ragas, not just for entertainment, but as a scheduled, non-pharmacological tool to help manage residents’ blood pressure. 

• Further research explores the effects of other ragas on different health parameters, creating a sophisticated “map” of how musical notes and structures interact with human physiology. 

The study concludes that instrumental Indian classical music, specifically Raag Malkauns, can “effectively reduce blood pressure in healthy older adults, suggesting its potential role as a non-pharmacological intervention for cardiovascular health and stress reduction.” 

In a world increasingly burdened by the costs and side-effects of pharmaceuticals, turning to the inherent wisdom of our cultural heritage—validated by the lens of modern science—offers a path to wellness that is not only effective but also deeply humane and accessible. The gentle notes of a flute, it seems, may indeed be a kind of medicine for the heart, in more ways than one.
