Introduction:The study was performed to analyze the effect of Yagya therapy on pulmonary functions among healthy college students.Methods:A total of 40 male participants were randomly selected and divided into two groups, i.e., the experimental group (n = 20) and the control group (n = 20). Participant’s age was ranged between 18 and 30 years (group age mean ± standard deviation = 22.20 ± 2.14 years). The experimental group performed Yagya in two sessions (morning and evening) every day for 34 days. Each session was for 30 min. The outcome measured assessed was (i) forced vital capacity (FVC), (ii) forced expiratory volume in the first second (FEV1), (iii) peak expiratory flow rate (PEFR), and (iv) maximum voluntary ventilation (MVV) at baseline and post.Results:The paired sample t-test showed that there was a significant increase in FVC, FEV1, and MVV for both experimental group and control group. The magnitude of change in FEV1 and MVV was little higher in the experimental group. The PEFR showed no significant changes in both groups. Independent sample t-test also showed no significant effect in favor of any assessed variables of both groups.Conclusions:The findings of the study indicate that the practice of Yagya shows slight or almost the same effect on pulmonary functions of the experimental as well as in the control groups. Hence, we can conclude that Yagya has no such specific improvement in pulmonary functions compared to usual care. Furthermore, larger-scale and well-designed randomized controlled trials should be highly encouraged to analyze the effect.
