What do Amy Adams, Julianne Moore and Christina Hendricks have in common? Well, it turns out that they all were all born with a natural, genetic health boost thanks to their flaming red hair. According to various studies collected by Erin La Rosa in her new hardcover, The Big Redhead Book , natural red heads—who only make up about two percent of the population—have a MC1R gene mutation that gives them some serious perks.

As pointed out by Refinery29 , a 2003 study reports that this mutation allows redheads to have a higher threshold for pain. Because of this, redheads often have issues with sedation when going under general anesthesia for surgery, necessitating more anesthesia than usual.
Additionally, redheads naturally produce more vitamin D within their bodies than others. Scientists theorize that this inherent gift is due to the fact that most redheads with pale skin live in cloudier regions of the world, forcing them to have adapted an improved ability to produce their own vitamin D. As a result, redheads are less likely to develop illnesses like arthritis and diabetes .
So, the next time you're about to crack another ‘ginger’ joke to your redhead friends, maybe rethink your actions. After all, genetics seem to be on their side in more ways than one.
