The down­falls of early risers

…A reduc­tion in brain activ­ity in areas asso­ci­ated with atten­tion was observed among the early birds. In addi­tion, they felt sleepy and demon­strated slow per­for­mance on their tests. As it got later in the day, the early ris­ers also exhib­ited less brain activ­ity in the region involved with the cir­ca­dian mas­ter clock that reg­u­lates alertness.

It’s good to be a night owl

In stark con­trast, the late ris­ers did not expe­ri­ence any slug­gish­ness and remained fully alert… “If we have found what can appear as an advan­tage for evening types, it’s that they are able to per­form well after 10.5 hours spent awake, and that they’re able to out­per­form morn­ing types.”

It ain’t easy being green

“Morn­ing types may be at an advan­tage, because their sched­ule is fit­ting bet­ter with the usual work sched­ule of the soci­ety… It may rep­re­sent a prob­lem for evening types obliged to wake up early while hav­ing dif­fi­cul­ties going to bed in the evening, even­tu­ally lead­ing to a sleep debt.” In addi­tion, early ris­ers expe­ri­ence a faster dis­si­pa­tion of sleep pres­sure when they do sleep and they feel restored more quickly than late night people.
