alt Hacker NewsThey worked best when everybody were farmers and had to get up early and go to bed early. Now most people don't live their lives centered around noon, our free time comes after our work is done at around 17:00, so having more light in the evening instead of worthless light in the night makes sense.
That's a myth.
Farmers have to wake up early because their animals wake up at sunrise and some tasks are best performed at that time. So they wake up before sunrise regardless of the clock time.
Human, like farm animals, are better off if they wake up at sunrise and go to sleep in full dark. At the equator that's easy, wake at 6, bed at 10PM. And standard work hours are 7-3 or 8-4.
