| Research Abstract |
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.
