食用冰淇淋过快导致脑结冰头痛

Scientists have explained why eating ice cream too quickly can cause a painful headache -- commonly known as brain freeze。

Researchers at the National University of Ireland in Galway and Harvard Medical School have found that the pain was brought on by a rapid increase in blood flow through a major blood vessel in the brain, the anterior cerebral artery, the Daily Telegraph reported。

They hope to use the discovery to develop new treatments for migraine。

科学家日前解释了为何食用冰淇淋速度过快会导致被称为“脑结冰”的严重头痛。

据英国《每日电讯报》报道，爱尔兰国立大学戈尔韦分校和哈佛医学院的研究人员共同发现，这种疼痛是由于脑部主要血管，即大脑前动脉中的血流量突然增加造成。

他们希望借助这项发现找出治疗偏头痛的方法。
