There are benefits to rising late as well. Some of them are similar to the ones listed in the article. If you are in your room by yourself, 1AM to 2AM tends to be a quiet and peaceful time. A lot of social activity also happens around midnight, and if you are an early riser you may find yourself burnt out and unable to participate by the time midnight rolls around. If you are forced to stay up late a few days in a row and you naturally wake up early as well, you may start accumulating a sleep deficit. A sleep deficit will eventually catch up to you and you'll stop appreciating those morning benefits. There was also an article posted a while back of a study done that showed people who tend to wake up late performed better on some cognitive tests at certain times of the day, while there was no similar advantage for people who naturally woke up early at any other times. I do think this article does point out some of the practical advantages that the experiment in that other article wasn't interested in; like how a sunrise makes you feel, the value of beating commute traffic, the value of getting a head start on daily activities, etc. (I like rising early and have tended to for the past 5-6 years. In my case, natural light and no drugs[1] is all it takes) [1] Alcohol, caffeine, as well as ibuprofen and other painkillers can all help me sleep through a sunrise.
