RESULTS
All seven meditators showed a small but statistically significant reduction in heart rate during meditation compared to the control period (P<0.001, paired "t" test, Table 1). There was a significant and comparable decrease in finger plethysmogram amplitude, during the meditation and control periods compared to the preceding periods (P<0.05, paired "t" test, in both cases). There was also a non-significant trend of reduction in the oxygen consumption following meditation (P>0.05, paired "t" test). The group average values ± SD for all 5 variables are as shown in Table 1.
