- tzs 8y agoThe sun at the highest point in the sky has little or no biological significance. Sunrise, on the other hand, is what our circadian rhythms sync to. If you spent a while living without clocks and with limited artificial lights, sleeping when tired and waking when it felt natural to do so, you would slip into a schedule based on sunrise.
