We investigated whether exposure to the odor of extracted cedar essence (CE) has (i) an influence on spontaneous activity and sleep-wake states of rats and (ii) a sleep-promoting effect on human daytime nap after taking an ordinary night's sleep. In rats exposed to CE, spontaneous activities and amount of wake were significantly decreased, while the amount of non-rapid eye movement (NREM) sleep was significantly increased. In human daytime nap, NREM sleep stage 2 latency was significantly shortened after exposure to CE.
我们研究了接触提取的雪松精油（CE）的气味是否（i）对大鼠的自发活动和睡眠-觉醒状态有影响，以及（ii）对正常夜间睡眠后的人类日间小睡是否有促睡眠作用。在接触CE的大鼠中，自发活动和觉醒量显著减少，而非快速眼动（NREM）睡眠量显著增加。在人类日间小睡中，接触CE后NREM睡眠2期潜伏期显著缩短。
