Systolic blood pressure, diastolic blood pressure, heart rate, and peripheral oxygen saturation in participants after bamboo forest and urban program. A paired t-test was used to compare the data between viewing and walking activities after three days of bamboo forest therapy. The data are presented as the mean ± SEs; * p < 0.05; significant difference between the data for viewing and walking activities was observed for the physiological indexes by paired t test. CS (n = 30), City site; YA (n = 30), Ya’an sites. YB (n = 30), Yibin sites. DJY (n = 30), Dujiangyan sites. (a) SBP, systolic blood pressure; (b) DBP, diastolic blood pressure; (c) HR, heart rate; (d) SpO2, peripheral oxygen saturation.
