10 Science-Backed Reasons for Sexual Attraction

Symmetry

When you’re describing how good-looking someone is, chances are you don’t say, “She/he is so symmetrical!” But multiple studies have revealed that a person’s “symmetry”—basically, how closely both sides of their face/body match—plays a big part in how attractive we find them. Of course, no one is perfectly symmetrical, because biology isn’t perfect. But the studies showed that, the lower a person’s oxidative stress levels, their higher the symmetry. Oxidative stress refers to imbalance in the body’s level of free radicals. Learn more about oxidative stress and how to lower it.

According to The Independent, “men who were rated as attractive by the women had significantly lower levels of oxidative stress.” Ten measurements were taken of the men to determine their symmetry—things as specific as ear height and finger length. Then they were tested and quizzed for indicators of oxidative stress. “Finally, a group of women were asked to rate images of the men’s bodies and faces for physical attractiveness. Men with more symmetrical bodies had lower levels and were rated as more attractive.” Find out what makes you more attractive to others.
