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 gingers¹ are less susceptible² 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。
