简要总结
This study tested the hypothesis that acute exposure to light during nighttime sleep adversely affects cardiometabolic function.
详细描述
This study tested the hypothesis that acute exposure to light during sleep adversely affects next morning glucose homeostasis and whether this effect occurs via reduced sleep quality, melatonin suppression, or sympathetic nervous system (SNS) activation during sleep. Twenty young adults participated in this parallel-group study design. The room light condition (n=10) included one night of sleep in dim light (< 3 lux) followed by one night of sleep with overhead room lighting (100 lux). The dim light condition (n=10) included two consecutive nights of sleep in dim light.
