Studies had already found that red haired people to be resistant to anesthesia. Now, the scientists at the University of Pittsburgh are proving that eye color could influence how you deal with pain, according to cancercenter.com.

Inna Belfer, explained the study found those with light-coloured eyes appeared to be less affected by pain compared to darker-colored eyes while giving birth, according to dailymail.co.uk.

“There may be certain phenotypes that predict or indicate a person’s response to pain stimuli or drug treatment for pain,” Inna Belfer, a professor of anaesthesiology at Pittsburgh University, stated in an interview with medscape.com.

Fifty-eight woman gave birth at a hospital and were classified into groups based on eyes. Twenty-four women in having brown or hazel eyes and thirty-four women containing blue or green eyes. They were profiled by using standard validated surveys to measure their response to pain, explained medscape.com.

In addition, lighter eyed woman experienced less anxiety after the birth, lower rates of depression and fewer negative thoughts Professor Belfer explained to the annual scientific meeting of the American Pain Society, reported dailymail.co.uk.

Melanin is a pigment located in the brain. The more you have, the quicker the brain works. A study from the 1990s demonstrated that people with dark eyes performed better on timed tests because they think faster from more melanin, reported essilorusa.com.

On the other hand, lighter-eyed people do not have as much melanin in the brain and therefore, slower reaction times. Research proves that the slower-thinking, light-eyed people tend to think more strategically than their dark-eyed counterparts, according to essilorusa.com.

Darker eyed individuals are affected more by alcohol and don’t need to drink as much to feel the effects because of the melanin in their brain. Scientists believe this contributes to why people with darker eyes are less likely to become alcoholics than light eyed people who have less melanin, explained essilorusa.com.

The results showed a trend in pain reduction, but were not statistically or clinically significant. Further research is needed for definitive conclusions about the possible connection between pain and eye color, explained essilorusa.com.
