The early bird gets to feel superior.
Morning types comprise about 40 percent of the population, according to University of California, Berkeley neuroscientist Matthew Walker, while evening types make up about 30 percent; the other 30 percent are somewhere in the middle. (“Essentially, a ‘morning’ person is up with the sunrise or shortly thereafter,”
Rebecca Robbins, a postdoctoral fellow at NYU Langone Health, told Moneyish.) But the world seems to favor so-called “larks,” or early risers whose unique rhythm of wakefulness and sleepiness lend themselves to a morning type: In one oft-quoted line, Ben Franklin claimed that “early to bed and early to rise makes a man healthy, wealthy and wise.”
For instance, people with self-reported later chronotypes — aka night owls — have a 10 percent increased risk of mortality relative to those with morning chronotypes, a UK study earlier this year found. Women early risers may be less likely to develop depression than those who aren’t, according to a June study. Bosses perceive folks with later start times to be less conscientious, per 2014 research; morning types even earn more than evening types, according to one 2012 Danish study. And larks have been shown to have higher levels of positive affect than owls, a 2012 study found.
Being a night owl may have its own perks: Evening-type participants in a 1999 studywere more likely to demonstrate higher intelligence. Research also suggests they have more sexual partners, with 2012 research suggesting that “eveningness is associated with psychological and behavioral traits that are instrumental in short-term mating strategies.”
