动物和人类的昼夜节律系统，周期长度接近但不完全是24小时，必须每天重置，以保持与外部环境时间同步。大多数哺乳动物都是通过经常暴露在光线和黑暗中来实现这个过程的。在本章中，我们回顾了过去25年来在我们实验室和其他实验室进行的研究结果，这些研究调查了光对人类昼夜节律系统的影响。这些研究揭示了光的时间、强度、持续时间和波长如何影响人类的生物钟。我们最近的研究也表明，关于光对人类昼夜节律系统的影响，还有很多东西有待了解。
The circadian system in animals and humans, being near but not exactly 24-hours in cycle length, must be reset on a daily basis in order to remain in synchrony with external environmental time. This process of entrainment is achieved in most mammals through regular exposure to light and darkness. In this chapter, we review the results of studies conducted in our laboratory and others over the past 25 years in which the effects of light on the human circadian timing system were investigated. These studies have revealed, how the timing, intensity, duration, and wavelength of light affect the human biological clock. Our most recent studies also demonstrate that there is much yet to learn about the effects of light on the human circadian timing system.
