(i) Root Mean Square of Successive Differences in RR Intervals (RMSSD) at baseline, post-condition and post-exposure for the yoga and rest conditions. Significant condition x time interaction, * p = 0 .042. (ii) Combined RMSSD at baseline, post-condition and post-exposure. Significant increase between baseline and post-condition (p = 0 .019), post-condition and post-exposure (*p = 0 .007), and between baseline and post-exposure,*** p < 0 .001. (iii) Low-frequency power in normalized units (LFN) at baseline, post-condition and post-exposure for the yoga and rest conditions. No significant difference between the yoga and rest conditions. (iv) Combined LFN at baseline, post-condition and post-exposure. Significant increase,* p = 0 .008, between post-condition and post-exposure. Note symbols or abbreviations on graphs: N.S.- not significant, *p < 0 .05, **p = 0 .001, and ***p < 0 .001. Error bars = SEM
