Effects of Quality of Light and Personal Traits on Human Physiological Functions

在低色温/低照度条件下的心算任务中，个体的特质焦虑得分与舒张压变化呈正相关。夏季的核心阈值间区(CIZ)大于冬季的2倍，5000K温度下的CIZ也大于红光和蓝光条件下的CIZ。晚间型个体夜间单色光睡眠时直肠温度下降幅度较小，尤其是早晨暴露在蓝光下。

There was a positive correlation between individual's trait anxiety scores and diastolic blood pressure changes during mental arithmetic task under low color temperature/low illuminance condition. The core interthreshold zone (CIZ) in summer was twice greater than that in winter, and the CIZ under 5000K was also greater than those under red light and blue light conditions. Evening-type individuals had a smaller rectal temperature decrease during nocturnal sleep by a monochromatic light, especially blue light exposure in the morning.
