Stress exposure affects lung function parameters along with other systemic effects. Yoga practice improve lung function and decrease risk for cardiorespiratory diseases. 50 stressed Manipuri women in the age group of 18-45 years were included in this study. Stress levels were assessed using the Holmes and Rahe Stress Scale, and Computerised Spirometer Helios 401was used to record various lung function parameters both before and after three (3) months of yoga training. Paired t test and one way ANOVA were used for analysis using statistical software SPSS version 21. Out of 50 participants, 8(16%) of them were low to moderately stressed, 32(64%) were highly stressed and 12(24%) were very highly stressed. Increase in lung function parameters such as FVC (p=0.000), FEV1 (p=0.000), PEFR (p=0.000), MVV (p=0.000), MEFR25-75% (p=0.000) and decrease in FEV1/FVC (p=0.000) were observed indicating improvement in lung function. Statistically significant improvement in lung function parameters was seen in stress level 2 and 3 suggesting the significant impact yoga have on stress. Thus, yoga therapy helps in improving lung function. Therefore, yoga may be adopted as a safe method in respiratory disorders for its preventive and therapeutic effects.
