The MC!R gene that can cause red hair codes for a receptor that is related to a family of receptors involved in perceiving pain, which may explain why mutations in MC1R would increase pain perception. Studies have shown that redheads have an increased sensitivity to anesthetics and require more general anesthetics than others. A 2009 study found that redheads were more anxious about dental visits, had more fear that they would experience pain during a visit, and were more than twice as likely to avoid dental care than those without the MC1R gene. Direct alcohol tolerance is largely dependent on body size. We also feel hot and cold differently. Because MC1R affects the body systemically, the mutation also dictates other differences in the ginger-haired. Redheads are believed to be bleeders during childbirth. An MC1R mutation may be involved in pain as well. However, they found that the pain tolerance was increased when the mice carried a MC1R variant. These hormones affect the balance between opioid receptors that inhibit pain (OPRM1) and melanocortin 4 receptors (MC4R) that increase pain sensitivity.
