Researchers say they’ve figured out what causes brain freeze — the mind-numbingly painful headache you get while eating ice cream or some other cold food. The finding may shed light on treatments for more severe headaches like migraines, the researchers suggest.
In a presentation on Sunday at the Experimental Biology 2012 meeting in San Francisco, a meeting bringing together researchers from six scientific societies, a U.S. team announced that brain freeze appears to be triggered by a sudden change in the flow of blood in the brain’s anterior cerebral artery. The pain comes on when blood flow increases, and subsides as soon as the artery constricts. >
