日间光暴露对睡眠的优化效果及作用机制
The optimization effects of daytime light exposure on sleep and its mechanisms
Abstracts
| 光照作为最重要的授时因子，对机体的昼夜节律与睡眠具有显著的调节作用。已有研究发现日间更多的光照暴露，特别是晨间高强度光照会显著促进个体的夜间睡眠，但这一优化效果会受到光照参数和个体特征等的调节。日间光照可以通过前置或延迟机体的生物节律进而对睡眠产生间接影响；而日光暴露是否会通过调节睡眠内稳态压力直接影响睡眠尚不明晰。未来研究可探究日光水平与时间对睡眠的交互影响，面向特定人群如长期室内办公者、轮班工作人员或睡眠障碍群体构建健康人因照明模式。 |
| [英文摘要]As a dominant Zeitgeber, ambient light can regulate sleep-wake patterns in humans. Exposure to higher light levels or more light exposure during the daytime, especially during the morning, positively predict nighttime sleep quality, but this effect is mediated by the light parameters (e.g., light level or spectrum), timing factors (e.g., time of day and duration), and light pattern. On the one hand, light can indirectly influence the sleep-wake cycle by regulating individuals’ circadian rhythms through the suprachiasmatic nucleus (SCN). On the other hand, light can directly affect sleep through the projection of melanopsin expressed by intrinsically photosensitive retinal ganglion cells (ipRGCs) to sleep- and wakefulness-related brain regions. However, there is still no clear consensus on whether light can affect sleep via regulation of sleep homeostatic process, which was another process driven the sleep-wake cycle. Future research should pay more attention on how to create “Human centric lighting” for those who work in the absence of daylight or need personal light to support their mental and physical requirement. |
