ScienceBiologyHuman Body
Quick Answer
Brain freeze is a sharp headache caused by eating something very cold too fast, which triggers a rapid change in blood flow to the brain.
The Full Story
Brain freeze, or cold-stimulus headache, happens when a cold food or drink rapidly chills the roof of the mouth. This sudden cooling causes blood vessels there to constrict and then quickly dilate, and nearby nerves β especially a major facial nerve β interpret the change as pain, which the brain refers to the forehead. The whole episode usually lasts only a few seconds to a minute. Warming the roof of the mouth with the tongue can end it faster.
