Abstract
In eight yoga instructors, we examined changes in brain rhythms and natural killer cell activity (NK activity) during yoga exercises. We found that th e practice of all three exercises studied resulted in increased alpha activ ity. There were no apparent changes in NK activity after a series of postur al (asana) and meditative (mantra) exercises. During respiratory exercises (pranayama), however, changes in Nk activity were observed in the eight sub jects, positively correlating to increases in alpha frequencies (r = 0.83, P < 0.02).
