Therefore, there is a need, especially for adolescents in the form of techniques or courses that can improve the reaction time. Yoga was found to cause a better improvement in the health of the individuals. The present study intended to show the effects of Bhramari pranayama (Bhr.P) on reaction time in the healthy adolescents.</jats:p></jats:sec><jats:sec id="j_ijamh-2019-0244_abs_002_w2aab3b7b1b1b6b1aab1c13b3Aa"><jats:title>Methods</jats:title><jats:p>Of the 730 potential subjects screened, 520 apparently healthy adolescents randomly assigned to either the Bhr.P group (n-260) or control group (n-260). Bhr.P group practiced the <jats:italic>bhramari pranayama</jats:italic> for 3 days in a week for 6 months. The Auditory Reaction Time (ART) and the Visual Reaction Time (VRT) were assessed before and after Bhr.P pranayama practice.</jats:p></jats:sec><jats:sec id="j_ijamh-2019-0244_abs_003_w2aab3b7b1b1b6b1aab1c13b4Aa"><jats:title>Results</jats:title><jats:p>Bhr.P group shows significant shortening of response time in both VRT (from 267.13 ± 52.65 to 249.87 ± 39.41 ms) and ART (from 237.42 ± 48.12 to 227.91 ± 34.60 ms) after 6 months of Bhr.P practice. In control group subjects, no such significant changes were found (p &gt; 0.05).</jats:p></jats:sec><jats:sec id="j_ijamh-2019-0244_abs_004_w2aab3b7b1b1b6b1aab1c13b5Aa"><jats:title>Conclusions</jats:title><jats:p>Shortening of RT implies an improvement in the information processing and reflexes. This beneficial effect of Bhr.P on reaction time can be used for improving cognitive function in the adolescents for their academic performances.</jats:p></jats:sec>

Effect of long-term yoga training on autonomic function among the healthy adults

“…Yoga practice reduces anxiety levels and minimizes the sympathetic hyperactivity induced by stress. [ 19 20 21 ] The reduction in sympathetic activity causes decreased catecholamine secretion. [ 22 ] This improves peripheral circulation by increasing the peripheral vascular dilatation resulting in reduced DBP.…”

“…The Bhramari pranayama was done for a duration of 20 min which approximately includes 20 cycles of Pranayama practice. Each cycle of practice was done at a rate of 3–6 breaths/minute, followed by 2-minute rest ( 17 ).…”

Role of yoga in stress management and implications in major depression disorder

“…Mindfulness techniques involve self-awareness, self-control, self-encouragement, without avoidance, judgement, or self-criticism, to recognize and sustain stressors as they are [ 52 ]. Yogic techniques enhance well-being, mood, attention, mental focus, and stress tolerance [ 53 ]. For depression and anxiety disorders, Mindful meditation and Yoga has been proved to have positive effects [ 54 ].…”
