“Unlocking the Secrets of Your Genes: What Your Physical Traits Really Say About You!”

Researchers from the University of Pittsburgh found a correlation between pain tolerance and eye color. While observing 58 pregnant women, scientists found that women with lighter eyes tolerated the pain of childbirth better. “Lighter eyes” meant blue and green eyes, while “darker eyes” were brown and hazel.

The link between pain tolerance and eye color is likely genetic. According to Dr. Jari Louhelainen, a biomolecular scientist, at least 12 gene variations control a person’s eye color. Dark eye color comes from melanin, a pigment that may heighten pain in some people.
