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, the higher their symmetry. Oxidative stress refers to imbalance in the body’s level of free radicals.
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.” Make sure you know these 12 things sex therapists won’t tell you.
The perfect body mass index
Your body mass index (BMI) refers to the relationship between your height and your weight. Calculate your BMI here to learn more about BMIs. The Independent reported that “a ratio of 20.85 has been found to be most attractive in women, because, say researchers, it is seen by men as a sign of good health and good reproductive potential.” Another study also assessed another body ratio, the waist-to-hip ratio. “In general, a range of 0.67 to 1.18 in females is attractive to men,” reports LiveScience. What does this mean? That you should love your curves—for reasons more than just attractiveness! According to The Independent, “one University of California study showed that women with larger hips perform better in intelligence tests, as do their children.” Here are the sex myths that everyone thinks are true but needs to ignore.
