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.

据英国《每日邮报》报道，丹麦科学家的研究显示，红头发的人对于寒冷更加敏感，也更容易牙疼。但他们还发现，红头发的人对于皮肤上的疼痛不怎么敏感，且不怕食物烫手。

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."

研究人员拉斯·阿里蒂逖说：测试显示，红头发的人对于这种特别的疼痛不太敏感。他们对于注射处近旁的压力或者针刺的反应不太强烈，就好像他们被保护的很好一样。这个发现真是太有意思了。

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

据估计，全世界有2%的人拥有红色的头发。
