PURPOSE: Spirometry is one of the most widely used Pulmonary Function Tests by physicians worldwide.Many breathing techniques and exercises have been tested to observe for improvement in lung function by spirometry, FEV1, FVC & PEFR in particular. Sudarshan Kriya Yoga (SKY) is a unique rhythmic breathing technique cognized by the world renowned spiritual leader and founder of Art Of Living Foundation Sri Sri Ravi Shankar. The neurophysiological and immunological effects of SKY have already been studied.We intended to study the effect of SKY on lung function of normal healthy adults.
METHODS: Study design : Observational prospective study. Setting :A Tertiary care hospital in Southern India .Subjects : 63 normal adult patients above 18 years (45 males,18 females )volunteered for the study. All subjects participated in a 1 week (18 hours)course of Art Of Living, inclusive of SKY.Spirometry was perfomed by a trained person for all the subjects by the Spiro USB of Micro Medical, UK .
RESULTS: The mean FEV 1 improved from 2.7397 L (pre SKY )to 2.7905 L (post SKY) (p > 0.05). The mean FVC improved from 3.1211 L (pre SKY) to 3.3275 L (post SKY) with p < 0.0001. The mean PEFR changed from 390.015 L/min (pre SKY) to 441.952L/min (post SKY ) which is highly significant (p < 0.0001).
CONCLUSION: There is a statistically significant increase in the two lung function parameters FVC and PEFR but not in FEV 1 after practising a short course of Sudarshan Kriya Yoga (SKY) among normal healthy adults.
CLINICAL IMPLICATIONS: SKY a simple and easily practised breathing technique, by improving the lung function of normal healthy adults, may have implications in serving as an adjunctive complementary treatment modality for improvement in lung function among the patients of obstructive airway disease, Asthmatics in particular.
