Answer 1

People used to get up when the sun raises, but they went to sleep about 8 hours before that, so their sleep lasted about 8 hours.

People see well enough at night to do some tasks in the evening after sunset.

It didn’t depend on the night length.

For people living in the extreme North where the night can last less than 9 hours in summer, they have to block the sun in the evening to get to sleep. Those places are also very cold, so people moved there when we were able to not build home that keep the heat and can block the sun.
