A Danish study has revealed that redheads are more sensitive to the cold and are more likely to suffer from toothaches. However the findings also indicate that gingers are less susceptible to skin pain and can handle hot food, Daily Mail reported.

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."

It is estimated that 2 percent of the world's population is redheaded.

紅頭發的人不怕疼

???????據英國《每日郵報》報道，丹麥科學家的研究顯示，紅頭發的人對于寒冷更加敏感，也更容易牙疼。但他們還發現，紅頭發的人對于皮膚上的疼痛不怎么敏感，且不怕食物燙手。

???????研究人員拉斯·阿里蒂逖說：“測試顯示，紅頭發的人對于這種特別的疼痛不太敏感。他們對于注射處近旁的壓力或者針刺的反應不太強烈，就好像他們被保護的很好一樣。這個發現真是太有意思了。”

???????據估計，全世界有2%的人擁有紅色的頭發。
