A University of Washington in Louisville study reported that natural redheads are more susceptible to pain and need more anesthesia when they go under the knife than do people with other hair colors. This confirms what anesthesiologists have suspected all along - that redheads can be a little harder to put under than others.
Scientists explained that redheads have a "defective receptor" for melanin, a pigment responsible for tanning. This same melanocortin-1 receptor cross-reacts with a related receptor on brain cells that influences pain sensitivity.
