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.
