Ever wonder why people sleep? Of course, there are plenty of reasons why we sleep. Primarily, coz we're tired of the days work or we're sleepy and we need to rest for a while. But, why do we really sleep? Can we not stay awake the whole day? Silly question? I just happen to ask coz my son who is 2 1/2 yrs old is starting to ask questions of me. He's starting to ask different what's and why's...

I think its a universal tradition. Basically we have made up our minds to sleep when the night falls! Technically we need sleep to get some enzymes which secrete while we sleep! Logically , its coz we need rest!

We sleep because as a human being we get tired and we have to rest and be relaxed...
