Most of the past studies of the lighting effect on human body focused only on discussions of the short term effect of lighting or color temperature changes on human physiological responses, failing to investigate the effect produced on human body by use of high illuminance and high color temperature lighting. In this study, 21 healthy participants between 21~30 years old were selected. We stimulated them with four different lighting conditions in 2000Lux-4000k, 2000Lux-6500k in contrast with 500Lux-4000k, and 500Lux-6500k respectively under precise controlled indoor environment qualities. The Ryodoraku measuring system was used to measure the human meridian responses for a duration of 3.5 hours. The statistically analyzed results are used to assess the participants’ physiological changes. The results showed that the effects on human meridians in different lighting with different duration were inconsistent. In the high illuminance lighting, Pericardium Meridian, Bladder Meridian, and Spleen Meridian were easily affected. In addition, with a prolonged illumination, we discovered that after lighting in 90 minutes, the human meridians were obviously affected with the high illuminance lighting (2000Lux). Prior to that, the effect of high color temperature lighting (6500K) was greater. However, on a high illuminance and high color temperature lighting (2000Lux-6500k), the majority of meridians were affected when the light was turned on initially and then within 30-45 minutes afterwards. The results showed that illuminance and color temperature were important influence factors of human physiological reaction. |
