Question:
Why do people tend to fall asleep at night time?
i mean why cant it be morning?
Answers:
It's called circadian rhythms, and it is a good question.
Just as bats are night animals and cows are day animals, humans are day animals. We are tuned to wake within a certain amount of time after it gets light, and to sleep better when it is totally dark.
We can change this for night work, etc., but it is hard on our bodies because we want to sleep in the dark and work in the day.
