7 Quick Redhead Facts

1. Scientists in 2005 from the University of Edinburgh found that redheads have a higher tolerance for pain than normal people.  This is because the MC1R mutation triggers the excess release of Pheomelanin, the hormone that stimulates melanocytes and Pheomelanin also stimulates a brain receptor related to pain sensitivity.
2. Approximately 4% of the world’s population are redheads
3. Red hair and green eyes were once thought to be the sign of a witch, a werewolf, or a vampire.
4. Redheads are harder to sedate than any other group, using most common anesthetics; they require on average about 20% more anesthesia.
5. The average adult redhead with a full head of hair has fewer number of hairs on their head than people with other hair colors (brunettes having the most hairs on average).
6. In Corsica, if you pass a redhead in the street you are to spit and turn around.
