ABSTRACT

Objectives: The aim of present study is to investigate the effect of regular Yoga practice for six months on the level of serum Adrenaline, serum cortisol and cardiovascular reactivity induced by cold pressor test. Materials and Methods: This study is conducted in the department of physiology, Medical College, Rewa MP. Study group comprises 60 healthy subjects of 18-25 years age group. The parameters like serum level of Adrenaline, serum cortisol, basal blood pressure, blood pressure before and after cold pressor test and pulse rate were recorded. Data were analyzed by using student‗t‘ test. Results: Regular practice of yoga significantly reduces the level of Adrenaline, serum cortisol and cardiovascular hyper-reactivity to cold pressor test. Out of 40 hyper-reactors to cold pressor test; 35 were converted in to hypo-reactor group after six months of yoga therapy (87.5%). Regular Yoga practice also reduces basal blood pressure, rise blood pressure and pulse rate after six month. Conclusion: We concluded that regular practice of yoga for six months reduced the possibly by inducing parasympathetic predominance and cortico-hypothalamo-medullary inhibition., who was hyper–reactive to cold stress, This shows that yoga provides significant improvement in aging to reduce the morbidity and mortality from stress induced disorders.
