Effect of Specific Yogasanas on Volunteers Having Cardiovascular HyperReactivity to Cold Pressor Test
Journal Title: Journal of Medical Science And clinical Research - Year 2014, Vol 2, Issue 4
Abstract
According to the World Health Organization, stress is a significant problem of our times and affects both physical as well as the mental health of people. Stress coping methods are the cognitive, behavioral and psychological efforts to deal with stress. The Yoga helps the person to control stress and hypertension. It offers gentle asanas, relaxation, pranayama and meditation which helps to calm your mind, teaching us to relax at will and giving a mental vacation. Numerous scientific studies have reported that yoga is beneficial both physiologically and psychologically. Stress reduction via Yoga has been shown to lower blood pressure levels and reduce cardiovascular risk in adults and adolescents. The aim of present study was to investigate whether practice of Yogasanas can reduce the prevalence of hyper-reactivity measured by cold-pressor test. The study group comprises 55 healthy medical students of 18-27 years age group. Initially there were 22 hyper-reactors to cold pressor test which reduce to 10 after practicing yogasanas for three months. The remaining subjects also reduce their reactivity to cold stress. Practice of “yogasanas” causes significant reduction in the cardiovascular hyper-reactivity. There was significant change in basal BP, BP after one minute of cold stress, rise in BP due to cold stress, heart rate and respiratory rate after performing yogasanas. The statistical analysis were carried out using student ‘t’ test. We concluded that regular practice of Yogasanas for three months reduces the cardiovascular hyper-reactivity to cold pressor test in subjects who were hyper-reactive to cold stress, possibly by inducing parasympathetic predominance and cortico-hypothalamo-medullary inhibition
