Your hair isn't the only thing that makes you unique. Here's how your DNA may influence your pain sensitivity, how fast you age, and more. Gingers stand out from the crowd for more than the bright hue of their hair. These folks carry two copies of a variant of the MC1R gene, which determines our hair and skin color.
Their redhead DNA also le to pale skin and cute freckles—but that's not all.
Research has revealed a handful of ways having red locks can affect a person's health, from how they feel pain hint: more intensely to their likelihood of developing various diseases. It's no secret that their pale skin makes gingers more susceptible to sunburns and skin cancers. But inresearchers actually discovered a link between redhead DNA and skin cancers with more mutations. Non-redhe aren't off the hook, either: Carrying just one copy of the recessive MC1R variant appeared to be tied to a bump in the of mutations linked to melanoma, the deadliest type of skin cancer.
It's another reminder of just how important it is to protect yourself from the sun's harmful rays no matter your hair color, and especially if you've got fiery locks. Fortunately for redhe, it doesn't take much sun exposure for their bodies to manufacture a healthy amount of vitamin D. Pale-skinned people are most efficient at synthesizing D, which is crucial for bone health, and is thought to protect against depression and fight off colds.
Vitamin D deficiency has also been linked a slew of health conditions, from hair loss to cancer.
Scottish experts have speculated that this ability gives redhe a genetic advantage in gloomy climatesbecause they can churn out more D in low-light conditions than people with darker skin or hair. Research suggests that redhe experience pain more intensely than others, and may even require more anesthesia for surgery.
The reason isn't entirely clear, but as this video from the American Chemical Society explains, one theory is that ginger DNA may heighten neural activity in the periaqueductal grey—a part of the brain that controls some pain sensation. You can blame your DNA: In a Current Biology study published last year, Dutch researchers found that adults who carried two copies of the MC1R gene variant typically appeared two years older than other white adults of the same age.
And it wasn't because gingers had more wrinkles which you might guess, since they're more prone to sun damage.
The gene variants were linked to other s of aging, such as thinning lips and sagging skin along the jaw line, the researchers said. Research published in in the British Journal of Cancer suggests that gingers have roughly half the risk of prostate cancer as men with light brown hair. The study did not reveal why this is true, but the authors speculated that one possible explanation might have something to do with vitamin D. By Anthea Levi Updated November 05, Save Pin FB More.
