|AimThe aim of this study was to investigate whether regular practice of Bhramari Pranayama and Yoganidra for 3 months can reduce cardiovascular hyper-reactivity to cold presser test in young healthy medical students.BackgroundA number of studies support the beneficial effect of Bhramari Pranayama and Yoganidra in hypertension. No study has been done to evaluate combined effect of pranayama and meditation in hyper-reactors to cold pressor test.
A total of 94 young medical students were selected who performed Bhramari Pranayama and Yoganidra for duration of three months. Cold presser test was done on each student before and after yoga.
There was 79% reduction in hyper-reactivity to cold presser test as number of hyper-reactors reduced from 32 before the study to 7 after three months of yoga. Systolic rise of blood pressure to cold presser test reduced from 20.1 ± 3.5 mm Hg to 15.2 ± 3.7 mm Hg (p<0.001) and diastolic rise reduced from 13.81 ± 3.4 mm Hg to 10.37 ± 2.62 mm Hg (p<0.001) in hyper-reactors. Mean systolic blood pressure in all the 94 subjects reduced from 119.87 ± 12.01 mm Hg to 117.68 ± 11.89 mm Hg whereas mean diastolic blood pressure reduced from 77.08 ± 9.3 mm Hg to 75.11 ± 9.07 mm Hg (p<0.001).
Bhramari Pranayama and Yoganidra together can significantly alleviate stress induced changes in cardiovascular parameters.
