Is there a genetic advantage to being a redhead? While numerous myths surround red-haired individuals, scientific research confirms that the gene responsible for red hair does confer some unique traits. According to Illustrerad Vetenskap, these include enhanced tolerance to pain and cold, as well as potential links to intelligence.

Redheads are often stereotyped as temperamental, sensitive, and intolerant of pain. However, beyond the myths, there is solid scientific evidence linking specific properties to the MC1R gene, which gives red hair its distinctive color.
Famous redheads owe their locks to the MC1R gene
Celebrities like Julianne Moore, Mick Hucknall, David Caruso, and Gillian Anderson can thank the tiny MC1R gene for their striking red curls, which have helped them stand out on stage and screen.
Actor Christopher Hivew attended the premiere of the final season of Game of Thrones with his wife.
But perhaps MC1R influences more than just hair color. Multiple studies on red-haired individuals suggest they handle spicy foods better, yet they are often thought to experience more pain and require higher doses of anesthesia.

A 2012 study from Aalborg University in Denmark found that redheads react differently to specific pain types, such as toothaches or pain from extreme cold. In fact, they might tolerate certain pain better. The MC1R gene plays multiple roles, including influencing how the brain processes pain signals.
Experiments indicate redheads are more sensitive to cold-induced pain but less reactive to heat burns. They also require larger amounts of anesthesia and painkillers. However, when it comes to injections, pressure, and spicy foods, redheads show greater resilience than others.
Could redheads be smarter on average? Danish scientists note that MC1R interacts with brain-related subgroups MC2R, MC3R, and MC4R, hinting at a possible link to intelligence. A British-American study found that redheads are four times more likely to become CEOs compared to others within the same demographic.
Redheads make up only about 2% of the global population. Scientists estimate that just two in every hundred people worldwide have natural red hair.
