Sleeping Late

The website Wired features an article titled 3 Smart Things About Sleeping Late which, as you likely suspect, lists and describes those three things.

The three points covered are the need by some for more sleep- ten hours being fine, the fact that night owls tend to be more creative than their early rising counterpats and the interesting fact that a stress hormone called cotisol is at a peak level in the blood around 7AM. Waking at that time may lead to a more tense day.
