3.1. Changes in Autonomic Nervous System Indicator Data
In this study, a paired-sample The differences in the variation in each group’s physiological indexes were analyzed through ANOVA and an LSD post test. Among the three stimulation conditions, there were no significant differences relative to the mean values from the baseline in the blood pressure, pulse pressure difference and pulse values (ΔSBP: control, −1.60 ± 1.14 mmHg; olfactory, −0.19 ± 1.01 mmHg; visual, −0.98 ± 1.62 mmHg; olfactory–visual, −0.58 ± 1.00 mmHg;
