“…Major contribution to this increase came from LF power. Similar results were reported during Suryanadi pranayama at 6 bpm without breath holding 10 . Changes in breathing frequency can override the haemodynamic fluctuations in both time and frequency domain parameters.…”

“…Regular practice of slow breathing exercise for three months improves autonomic functions 8 , and sympathetic tone reduction is observed with seven days’ practice of slow breathing 9 . A few studies conducted on the immediate effect of slow yogic breathing have reported that the right nostril breathing has sympathomimetic effect whereas the left nostril breathing has parasympathomimetic effect 10 11 .…”

Background & objectives: Breathing exercises are believed to modulate the cardiovascular oscillations in the body. To assess the validity of the assumption and understand the underlying mechanism, the key autonomic regulatory parameters such as heart rate variability (HRV), blood pressure variability (BPV) and baroreflex sensitivity (BRS) were recorded during controlled slow yogic breathing. Alternate nostril breathing (ANB) was selected as the yogic manoeuvre. Methods: Twelve healthy volunteers (age 30±3.8 yr) participated in the study. ANB was performed at a breathing frequency of 5 breaths per minute (bpm). In each participant, the electrocardiogram, respiratory movements, beat-to-beat BP and end-tidal carbon dioxide were recorded for five minutes each: before, during and after ANB. The records were analyzed for HRV, BPV and BRS. Results: During ANB, HRV analysis showed significant increase in the standard deviation of all NN intervals, low-frequency (LF) component, LF/HF (low frequency/high frequency) ratio and significant decrease in the HF component. BPV analysis showed a significant increase in total power in systolic BPV (SBPV), diastolic BPV (DBPV) and mean BPV. BRS analysis showed a significant increase in the total number of sequences in SBPV and DBPV and significant augmentation of α-LF and reduction in α-HF. The power spectrum showed a dominant peak in HRV at 0.08 Hz (LF component) similar to the respiratory frequency. The acute short-term change in circulatory control system declined immediately after the cessation of slow yogic breathing (ANB) and remained elevated in post-ANB stage as compared to the pre-ANB. Interpretation & conclusions: Significant increase in cardiovascular oscillations and baroreflex recruitments during-ANB suggested a dynamic interaction between respiratory and cardiovascular system. Enhanced phasic relationship with some delay indicated the complexity of the system. It indicated that respiratory and cardiovascular oscillations were coupled through multiple regulatory mechanisms, such as mechanical coupling, baroreflex and central cardiovascular control.

“…Pranayamic breathing practiced exclusively via either nostril has opposite effects on right nostril breathing increases sympathetic activity while left nostril decreases it. [17,30] When the respiratory cycle of inhalation and exhalation is completed through the left nostril alone the practice is called "Chandra Anulomaa Vilomaa Pranayam" which means a heat dissipating or cooling liberating practice [31]. This study found remarkable fall of pulse rate, respiratory rate, systolic blood pressure and diastolic blood pressure after CAV Pranayama among Naïve group but the fall was found to be significant in SBP only (at p < 0.05).…”

Background and Objectives: In recent years, there has been considerable interest in scientific research on yoga, especially on Pranayama. Nostril breathing exercises including Alternate nostril breathing, Left nostril breathing and right nostril breathing exercises is getting attention in the east and in the west. Left nostril breathing exercises is also called Chandra Nadisuddhi Pranayama or Chandra anulomaa vilomaa Pranayama (CAV). Very few have carried out research on Chandra Anuloma Viloma Pranayama (CAV). This study was carried out to see the effects of CAV on experienced yoga practitioners and naïves.Material and Methods: The study consisted of 36 subjects divided into two groups, first group consist of 26 medical students who were naïve and the next group consist of 10 yoga practitioners. All the subjects performed 12 rounds of Chandra Nadisuddhi Pranayama in each session for 24 days. Variables were entered into SPSS Program and were analyzed.Results: This study depicts fall in Pulse rate, respiratory rate, systolic blood pressure and Diastolic blood pressure after CAV Pranayama in both Naïves and Yoga practitioners. But the significant drop was observed in SBP only (at p < 0.05) among Naives and in all parameters except respiratory rate among Yoga Practitioners.Conclusion: The effect of the Chandra Anuloma Viloma (CAV) in this study was more eminent in the yoga practitioners than in the naïve group.Janaki Medical College Journal of Medical Sciences (2015) Vol. 3 (1):45-51

“…As a Canadian Yogacharya responded, “hard to single one out, but studies on alternative nostril breathing [ 18 , 20 - 22 ], for instance, have influenced my own practice, and have allowed me to consider gradually incorporating these techniques, which I normally would have deemed too advanced, into some of my classes.”…”

Introduction:Yoga has become popular worldwide with increasing research done on its therapeutic potential. However, it remains to be determined whether such findings actually percolate down into teaching and practice of Yoga teachers/therapists.Materials and Methods:The aim of this survey was to document awareness of Yoga research findings in the Yoga community and find out how these were utilized. It was undertaken with a select group of 34 international Yoga teachers and therapists utilizing email and social media between August and December 2015. Majority of responders had well-established reputation in Yoga and were from diverse lineages with 30 of them having more than 5 years of experience in the field. A set of eight questions were sent to them related to essentiality of Yoga research, how they updated themselves on research findings and whether such studies influenced their teaching and practice. Responses were compiled and appropriate statistics determined for quantitative aspects while feedback, comments and suggestions were noted in detail.Results and Discussion:About 89% agreed that it was essential to be up-to-date on Yoga research but only 70% updated themselves regularly with average papers read fully per year being <10. Most accessed information through general news reports, emails from contacts, and articles on internet sites whereas only 7% were through PubMed. About 60% felt these studies helped them in general teaching whereas 20% said that such studies had not really influenced it in any way.Conclusion:This survey provides a basic picture of a general lack of awareness of Yoga research amongst practicing Yoga teachers and therapists. Though a majority agree research is important, few seriously update themselves on this through scientific channels. With regard to future studies, most wanted “proof” that could be used to convince potential clients and felt that more qualitative methods should be applied.
