"The Hidden Brilliance of Late Risers"

huffingtonpost.com If you're a late riser, there's a good chance that you have, at one point, been made to feel inferior to the seeming moral superiority of your early riser friends and colleagues. Unlike early birds (people who have a genetic tendency to go to bed and wake up early), late risers, also known as night owls, have a natural tendency to go to bed late and sleep even later [1]. And that's just fine. Although you may sleep though the early morning hours, which many early birds claim are their most productive of the day, for night owls these productive hours manifest themselves much later in the day. An Undeserved Stigma In night owls, melatonin secretion begins very late [2], which makes it easy for them to stay awake (and productive) well into the night. Because of this, as quoted from Sleep: A Very Short Introduction [3] by Steven W. Lockley and Russell:

Evening types wake earlier in their circadian "day" and are therefore more sleepy and poorer performers in the morning but do not decline as much as morning types by the end of the day.

The undeserved "lazy" stigma given to night owls comes about due to the early birds of the world never seeing you at your most productive because, ironically, they're often fast asleep by the time you get going.
