Redheads don't need any excuse to celebrate their ginger hair, but St. Patrick's Day is one date on the calendar where they can do just that – it's an unofficial redhead holiday!

It won't be unusual for many redheads to be spending most of the day hearing comments like "Oh, you're ginger? You must be Irish". But why is it so commonly believed that natural gingers have Irish heritage?

Here are the facts/theories to celebrate redheads this St. Patrick's Day

They may not beat Scotland with the highest percentage of gingerness at 13%, but the Emerald Isle comes in second with a respectable 10%. And it has also been estimated that around 46% of the country's population carries the ginger gene, known as MC1R, that is responsible for red hair to occur. These people don't have to have red hair themselves, so we like to call these people "secret gingers."

Thanks to our ginger genetics, natural redheads can create vitamin D under much lower UV conditions. And we all know how much redheads are better off in the shade and out of the sun. It's even believed that gingers feel heat pain and changes in temperature more than other hair shades, so it's better to keep us in mild and cloudy climes.
