The wood ratios (the ratio of the area covered with wooden material to the whole area of the ceiling, walls, and floor) of the rooms were 0%, 45%, and 90%. Subjective evaluation was also conducted. In the 0% room, diastolic blood pressure decreased significantly, but the observed change in the autonomic nervous activity was relatively small. In the 45% room, a significant decrease in the diastolic blood pressure and a significant increase in pulse rate were observed. This room tended to have the highest scores in subjective "comfortable” feeling. The 90% room caused significant and large decreases in systolic blood pressure and diastolic blood pressure at the beginning of the test, but the large coverage of wood appeared to cause a rapid decrease in brain activity and an increase in pulse rate. The present study demonstrated that a difference in wood ratio in the interior caused different physiological responses, especially in the autonomic nervous activity, by using actual-size rooms for the first time.
