What I mean by this is:
Humans naturally become tired when the sun goes down. We usually find it hard to sleep during the day. Astronauts orbiting around Earth have a difficult time getting sleep because the sun is constantly moving in and out of view.
Say, if someone worked the graveyard shift every day for a year, would he become nocturnal, or would he still have trouble sleeping during the day?
