ABSTRACT

Background: Stress may be defined as psychophysiological process
usually experienced as a negative emotional state. It is a common
condition, a response to a physical threat or psychological distress that
generates a host of chemical and hormonal reactions in the body. The
health effects of stress involve mainly autonomic, cardiovascular, and
immune systems. Objective: The aim of present study was to
investigate whether regular practice of Yoga for three months can
reduce cardiovascular and respiratory reactivity induced by cold
pressor test. Material and method: The present study included 60
male medical students of first M.B.B.S. of 18 to 25 years of age. After
recording the basal blood pressure and pulse rate, and the cardiovascular reactivity of all the
60 students was measured by application of cold pressor test devised by Hines & Brown
(1936). 35 were found to be hyper reactor to this test. These hyper reactors underwent
Yogasana, Nadishodhana, Bhramari Pranayama, Omkar Chanting and meditation for the
duration of 12 weeks. Before and After the yogic training period the plasma Adrenaline level,
mean blood pressure and mean pulse rate/ min was measured which was found to be
significantly reduced. Statistically by using student„t‟ test. Result: Regular practice of yoga
for 3 months significantly reduced the cardiovascular reactivity to cold pressor test, plasma
Adrenaline level basal blood pressure and pulse rate. Conclusion: We concluded that regular
practice of yoga for three months reduced the plasma Adrenaline level and cardiovascular
parameters and. Possibly by inducing parasympathetic predominance and corticohypothalamo-
medullary inhibition
