Responsiveness of free-running human circadian rhythms to a single pulse of bright light was examined in a temporal isolation unit. Bright light (5000 lx) of either 3 or 6 h duration, applied during the early subjective day, produced phase-advance shifts in both the sleep-wake cycle and the rhythm of rectal temperature; the light pulse had essentially no effect on the phase of the circadian rhythms, when it was introduced during the late subjective day or the early subjective night. The results indicate that bright light can reset the human circadian pacemaker.
在一个时间隔离单元中，研究了自由运行的人体昼夜节律对单次强光脉冲的反应。在主观日早期施加持续3或6小时的强光（5000勒克斯），会使睡眠-觉醒周期和直肠温度节律产生相位提前变化；当在主观日晚期或主观夜早期引入光脉冲时，其对昼夜节律的相位基本没有影响。结果表明，强光可以重置人体昼夜节律起搏器。
