What is the relationship between illumination and health? The human body has its own biological clock. For thousands of years, people have been living in the way of sunrise and sunset, but the emergence of artificial light has greatly delayed the time of sunset and sunset. First of all, light affects our physiological rhythm system, in which the phase shift of sleep waking rhythm is most strongly stimulated by lighting. So without pulling the curtains to sleep, summer always wakes up earlier than winter, because the physiological rhythm system is affected by natural light for waking time. Based on this rule, by providing different illumination exposure and exposure time, the rhythm time can be shifted, and the biological clock of falling asleep and waking can be adjusted forward or backward as needed.
At present, the illumination of indoor lamps can produce effects similar to natural light on physiological rhythm system. That's why it's hard to fall asleep after turning on the light and going to the toilet at night.
In short, over the past century, mankind has made fruitful achievements in the tireless exploration of light and health research. But there are also many unknown areas that need to be explored urgently.
