食用冰淇淋過快導致腦結冰頭痛

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。

科學家日前解釋了爲何食用冰淇淋速度過快會導致被稱爲“腦結冰”的嚴重頭痛。

據英國《每日電訊報》報道，愛爾蘭國立大學戈爾韋分校和哈佛醫學院的研究人員共同發現，這種疼痛是由於腦部主要血管，即大腦前動脈中的血流量突然增加造成。

他們希望藉助這項發現找出治療偏頭痛的方法。
