Abstract
We showed 2 images such as photos with sunshine filtering through the foliage (SFTF) and control in the forest as a simulation for 17 subjects, and examined the change in the physiology index (pulse, blood pressure, brain blood stream) during the experiment, as well as subjective evaluations for each stimulation after the experiment. Consequently, between SFTF and control, a significant difference was confirmed in some of a subjective evaluation and physiological index. In addition, quantity of brain blood flow on right prefrontal cortex significantly decreased by SFTF in comparison with the baseline. As a result of the multiple regression analysis, it were suggested that a higher appraisal of cheerfulness for SFTF may bring a decreasing of a diastolic pressure and a higher appraisal of nature quality for it may do a decreasing of whole amount of hemoglobin.
