| Abstract: | I examined the effects of yoga and Photic feedback (PFB) to natural killer cell activity (NK activity). In eight yoga instructors, I examined changes in brain rhythms and NK activity during yoga exercises. I found that the practice of all three exercises studied resulted in increased alpha activity. There were no apparent changes in NK activity after a series of postural (asana) and med.tative (mantra) exercises. During respiratory exercises (pranayama), however, changes in NK activity were observed in the eight subjects, positively correlating to increases in alpha frequencies (r =0.83, p<0.02) . PFB system stimulates the subject's alpha rhythms caused by the feedback. Thirteen healthy male subjects aged 20-35 were exposed to PFB and were stimulated at 1OHz for 20 minutes twice a day. The experiments wore continued for 11 days. At the 21st PFB, the NK activities before/after the stimuli were measured. The levels of NK activities changed during the experiment in association with the standard deviations of frequencies of alpha waves detected in the forehead (r =-0.67, p < 0.05) . These studies suggest that whatever relaxation technique with the activation of alpha waves would increase peripheral NK activity.
