Redheads are more sensitive to some kinds of pain and less sensitive to others. The explanation for these differences could be found in their genetic makeup.
thenewgreen: I dated a redhead for close to 5 years. She was a pretty tough cookie but her skin was pretty sensitive to bug bites. We were picnicking once and she got close to 50 mosquito bites on her feet. It hurt so bad she wanted me to take her to the ER. I don't think she wasn't afraid to go in the sun, but she wore a lot of hats.
