Key result
Daily Nadi Shodhana Pranayama increases SpO2 and perfusion index while reducing resting pulse rate.
Why the study?
Regular practice of Nadi Shodhana Pranayama is known to improve cardiovascular and respiratory efficiency, but its effects on SpO2, RPR, and PI required evaluation in young healthy individuals.
Does Nadi Shodhana Pranayama improve peripheral oxygen saturation, resting pulse rate, and perfusion index in young healthy individuals?
RCT (n=110)
Does Nadi Shodhana Pranayama improve peripheral oxygen saturation, resting pulse rate, and perfusion index in young healthy individuals?
Regular practice of Nadi Shodhana Pranayama for 8 weeks significantly improves oxygen saturation, perfusion index, and resting pulse rate in young healthy individuals.
NSP effects on SpO2, RPR, and PI in healthy youth remain hypothesis-generating; prospective RCTs needed before any clinical consideration.
A BSTRACT Background: Regular practice of Nadi Shodhana Pranayama (NSP) is known to improve cardiovascular and respiratory efficiency, enhance parasympathetic activity, reduce stress, and promote overall physical and mental health. It may also improve blood oxygenation, perfusion index (PI), and resting pulse rate (RPR). Aim: To evaluate the effect of NSP on peripheral oxygen saturation (SpO 2 ), RPR, and PI in young healthy individuals. Materials and Methods: A total of 110 volunteers aged 18–25 years were selected based on the inclusion and exclusion criteria and randomly divided into control ( n = 55) and experimental ( n = 55) groups. Baseline measurements of SpO 2 , RPR, and PI were recorded. The experimental group practiced NSP for 30 min daily for 8 weeks, while the control group did not receive any intervention. Postintervention measurements were recorded and analyzed. Results: Significant improvements were observed after the intervention. SpO 2 increased from 97.34 ± 0.67 to 98.98 ± 0.13, PI increased from 10.11 ± 1.696 to 11.85 ± 1.919, and RPR decreased from 74.20 ± 1.889 to 68.98 ± 1.870. Conclusion: The findings suggest that regular practice of NSP significantly enhances oxygen saturation and PI, while reducing RPR in young healthy individuals. These changes indicate improved cardiovascular efficiency, better tissue oxygenation, and reduced physiological stress.

Sahu et al. (2026) conducted an RCT in Healthy (n=110). Nadi Shodhana Pranayama vs. No intervention was evaluated on Peripheral oxygen saturation (SpO2), resting pulse rate (RPR), and perfusion index (PI). Daily practice of Nadi Shodhana Pranayama for 8 weeks significantly increased peripheral oxygen saturation (from 97.34 to 98.98) and perfusion index, and reduced resting pulse rate.
