Role of sudarshan kriya and pranayam on lipid profile and blood cell parameters during exam stress: A randomized controlled trial.
Int J Yoga. 2012 Jan ;5(1):21-7. PMID: 22346062
BACKGROUND: Yoga is a science practiced in India over thousands of years. It produces constituent physiological changes and has sound scientific basis.
AIM: Since exam stress modifies lipid profile and hematological parameters, we conducted an investigation on the effect of sudarshan kriya (SK and P) program on these parameters.
MATERIALS AND METHODS: Blood samples of 43 engineering students were collected at four intervals namely baseline (BL), exam stress (ES), three and six weeks practice of SK and P during exam stress. Lipid profile and hematological parameters were measured at all four intervals.
RESULTS: ES elevated total cholesterol (TC), triglycerides (TGL) and very low density lipoprotein (VLDL) levels. Hematological parameters affected by ES included neutrophil, lymphocytes, platelet count, packed cell volume (PCV) and mean cell volume (MCV). Three and six weeks practice of SK and P reduced the elevated lipid profile, hematological parameters and improved lymphocyte levels.
CONCLUSION: Our study indicates that SK and P practice has the potential to overcome ES by improving lipid profile and hematological parameters.
