Here's what the scientists have figured out: woman who stay up late are more likely to end their nights with a booty call, while the ladies who are early to bed and early to rise are more likely to end up in a relationship. Now, honestly, what do you prefer?
According to the study, cited in Time (link below), "Researchers found that men generally have higher levels of cortisol and testosterone than women, but that night-owl women have just as much cortisol as men. High levels of cortisol are usually associated with high energy, arousability, stress and even cognitive function, and some research has shown that successful people usually have higher cortisol levels. The researchers found that high cortisol levels may explain why night-owls take more risks."
In English that means stay up late and get your sex on.
"Apparently the tendency to stay up late may have been an evolutionary trait that enabled our caveman ancestors to get frisky after the kids went to bed. 'From an evolutionary perspective, it has been suggested that the night-owl trait may have evolved to facilitate short-term mating, that is, sexual interactions that occur outside of committed, monogamous relationships,' lead researcher Dario Maestripieri told UChicago News. 'Being active in the evening hours increased the opportunities to engage in social and mating activities, when adults were less burdened by work or child-rearing.'"
Put those sleeping pills in the garbage, start drinking more coffee, and for the love of God, don't go to bed until someone hot and bothered is with you.
