Daylight has been tied to humanity since the dawn of our existence. Daylight is what grows the plants that help sustain our food sources and create oxygen. Daylight is the light source that has shaped human evolution from the beginning.
It’s only in the last 100 years that humans began using electric lights. More than just the visual, we feel daylight, it sets our circadian rhythms, connecting us to sky conditions and letting us intuitively know the time of day and year. It helps us know when we should be awake, and (in its absence) when we should be asleep.
