Stronger Bones, Immune System Some biologists believe that the reason there are more redheads in cold, cloudy climes, such as Scotland, is that the pale skin that typically accompanies a fiery mane allows the body to soak more vitamin D. Not only does D help protect against many diseases, but it’s essential for healthy bones—and helps ward off osteoporosis, the brittle-bone disease that leads to fractures. At a recent seminar on hair color and health, Scottish researcher Jonathan Rees reported that throughout history the “ginger gene” may have “played a big role” in protecting many redheads from rickets (soft, weak bones triggered by vitamin D deficiency). He added that, “there’s also good data that we need vitamin D to fight against infections like tuberculosis,” the world’s most common contagious disease.

Although it is said that people with red hair tend to bleed out and clot more slowly than people with other hair colors this is not supported by evidence, however redheads are harder to operate on because of a difference in sensitivity to different anesthesia types.
