It turns out that gingers are less sensitive to stinging pain in the skin, according to researchers who injected capsicum, the active ingredient in chillies, into the arms of patients. Professor Lars Arendt-Nielsen, one of the researchers, said:
"Our tests showed that redheads are less sensitive to this particular type of pain. They react less to pressure close to the injected area, or to a pinprick. They seem to be a bit better protected, and that is a really interesting finding."
The finding also means redheads can handle spicier food, reports Science Nordic. It lends some scientific weight to previous suggestions that gingers have a different pain response to the rest of, which were even investigated by Myth Busters.
All of which points to the fact that there is a ginger gene that brings with it these subtle differences. Proof, if you needed it, that gingers aren't just different; they're better. [Science Nordic]
