應用良導絡量測評估色溫度對人體生理反應之影響

Evaluation of the Effect of Color Temperature Changes on Human Physiological Responses Based on the Ryodoraku Measurements

以往有關室內環境光源色溫度與人體生理反應之關係的研究，大多是探討心電圖、腦波…等單一生理反應，未能評估整體的生理反應。本研究嘗試以目前中醫界用於評估針灸療效的「良導絡量測系統」，來評估室內光環境變化等「非接觸式」的環境刺激對人體的影響及探討以其量測人體整體生理反應之可行性。本研究篩選二十四位健康的受測者，在精確控制室內環境變因下，接受照度500lux，色溫度分別為2700K、4000K 及6500K等三種光環境變化的刺激，運用良導絡量測系統測定其生理反應。測定結果經統計分析後，用以評估受測者生理反應的變化。實驗結果顯示良導絡量測系統可有效量測人體生理反應，而在三種色溫度中以6500K的高色溫環境對人體刺激性較大。

In the previous studies, the relationship between the changes of color temperature and the corresponding human physiological responses was usually surveyed by using single physiological measurement such as electrocardiogram, brain waves, etc. The whole body responses were seldom evaluated. In our study, the “systematic measurements of Ryodoraku”, which is currently widely used in the area of Chinese medicine to assess the benefits of acupuncture treatments, was used to study the effects of the “noncontact environmental stimulation”, such as color temperature changes, on human physiological responses. It is also used to study the availability of evaluating the whole body responses. In this study, 24 healthy participants were selected. We stimulated them with three different lighting environment with an intensity of 500lux and color temperature changes in 2700K, 4000K,and 6500K respectively under precise controlled indoor environment qualities, such as thermal comfort, sound noise level. The Ryodoraku measuring system was used to measure the human physiological responses. The statistically analyzed results are used to assess the participants’ physiological changes. The results showed that the Ryodoraku measuring system can measure the human physiological changes effectively. Among the 3 color temperatures, the high 6500K color temperature has the biggest effect on human physiological responses.
