My natural sleep cycle isn't like that. I have a tendency to be up all night, and prefer to sleep during the day. However, it is documented that the circadian rhythm (the 24 hour cycle) has a lot to do with sleep/wake cycles. Sunlight and temperature can most definitely have an effect on us.

I aint any prof but,I think i can answer it with simple logic that...
Because our ancestors(homo sapiens and all those dudes) used to do it that way,they would hunt for all day long,eat some preserve some,coz at night it would be impossible to run leave hunting alone......
So the main point is,they didnt have anything to do at night(not anything they could do) they used to sleep at night rather than at daytime.
Had we evoluted with EYEs of an owl we could have been awake at night [partying :)] and asleep at morning [I sleep anyway].
Well,thats it.

we wake up in the morning and sleep at night because its how our body responds to the cycle each day.

Get yourself a good drug habit and this will change real fast. They don't call the Coca-nuts Vampires for nothing.
The real answer is racial memory. We were defenceless in the dark until artificial light was introudced. Fort up during the dark. Work and hunt during the day. The best way to stay alive.

Err because at night, it's more dangerous as most people get killed during the night. So people sleep at night and are awake at day cause it's more safe.

evey why has no explanation
why sun rises in east
why man dies
why babies are born > why man get erection > woman love to suffer labour pain >>
all are natural forces
working according to Law of the Nature. and it is so that night you feel tired and sleep
sun makes you awake
unless you are working in shifts , you have to wake up in moring
