Apparently, ladies who like to stay up late are more likely to get laid, according to a new study.
The study, sponsored by University of Chicago, indicates that women who regard themselves as night-owls have similar risk-taking behaviours to the opposite sex. Both men and women who prefer to stay up late are also believed to have more sex, but fewer serious relationships.
Researchers are attributing this trend to the levels of the hormone cortisol in night-owl women. Although men generally have more cortisol and testosterone compared to women, females who are awake late at night more frequently have the same amount of cortisol as men.
High levels of cortisol are commonly believed to lead to tons of energy, arousal and stress, which all seem like great reasons as to why these women are more likely to be getting it on.
Additionally, other research showed that higher cortisol levels lead to greater success in various aspects of life. So, maybe all that sex these people are having late into the night is paying off. More reason to do so then!
