There is always a problem with sleeping throughout the day. You won't be able to sleep at night. It's annoying. No matter how long you sleep during the day, night sleep is essential. The weather at night is usually perfect. But sleeping at night is more of a psychological trigger. There might be some people that are trained to work during the night and sleep during the day. It's not like there is a sort of sleep pill poured all over the air. We have only adapted to sleeping at night and not during the day.
