Less Vitamin D
Interestingly, redheads can also survive with less vitamin D from the sun than others. The reason why is that many redheads are from European descent, and so their skin is used to colder and cloudier climates. In turn, their bodies create more vitamin D on their own than people from sunnier locations that require more time outside to get more vitamin D.
They Get More Laughs
Interestingly, dating back to the 19th century, people found redheads to be funnier than others, which is why so many clowns will put on a red wig. Several studies done at the University of Buffalo found that people perceived clowns with red wigs to be funnier than those wearing other colors.
