Werner Habermehl, PhD, from the Hamburg Research Institute in Germany, looked at the sex lives and hair color of hundreds of German women. The sex lives of women with red hair were clearly more active than those with other hair color, Dr. Habermehl said in a press release. The research shows that the fiery redhead certainly lives up to her reputation.

Redheads may curse the pale complexion that often accompanies their cherry tresses, but scientists have found that fair skin has an important anti-disease property. It soaks up more vitamin D, which is essential for bone health and preventing osteoporosis. Some researchers believe it may also boost immunity and help prevent some cancers and autoimmune diseases.

Red hair is a mutation of the MC1R gene on chromosome 16. The mutation blocks the production of eumelanin dark brown and black pigment, which causes a buildup of the phaeomelanin red and blond pigments. Some scientists believe that higher levels of phaeomelanin may produce more mutations and dangerous effects when exposed to UV radiation.

Redheads may also be more susceptible to Parkinsons disease. According to a Harvard study, people with red hair have a nearly 90 percent higher risk for the neurological disorder, which causes progressive difficulties with balance and coordination. Scientists arent completely sure why theres a connection, but they believe it may have to do with a mutation in a red hair-related gene that also spells a higher risk for Parkinsons.

Scholars note that redheads have influenced history out of proportion to their numbers. Famous redheads include Roman emperor Nero, Helen of Troy, Cleopatra, the ancient god of love Aphrodite, Queen Elizabeth I, Napoleon Bonaparte, Oliver Cromwell, Emily Dickinson, Antonio Vivaldi, Thomas Jefferson, Vincent Van Gogh, Mark Twain, James Joyce, Winston Churchill, Malcolm X, Galileo, and King David.

Despite a long-running rumor that redheads deserve a spot on the endangered species list, gingers are here to stay. While only 4 percent of the worlds population carries the recessive redhead gene, according to the Oxford Hair Foundation, that number will probably only decrease as redheads reproduce with non-redheads. So over time, red hair may become more rare, but theyll be here forever, Barry Star, PhD, a genetics professor at Stanford University, told The Boston Globe. Thats because 4 percent of the population is still a pretty huge number too large to be wiped out.

redheads are thin-skinned when it comes to pain tolerance. Research shows that they require about 20 percent more anesthesia than blondes or brunettes, possibly because theyre more resistant to pain medications like Novocain, according to a study published in the journal Anesthesiology. Theyre also more sensitive to pain caused by cold and hot temperatures.
