Physiological effects in humans induced by the visual stimulation of room interiors with different wood quantities

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