Pain that resolves within a few seconds to a few minutes after it begins.Intense, stabbing pain in the forehead and temples.Quick onset of head pain, peaking within 30 to 60 seconds of cold exposure, according to an article published in The British Medical Journal.When the cold stimulus is removed, the blood vessels go back to their normal size and the pain tends to go away, Goldberg said.Despite being called "brain freeze," this brief episode of head pain doesn't cause permanent damage and isn't life-threatening. Once the trigeminal nerve is triggered, blood vessels inside the head momentarily tighten and constrict and then rapidly dilate or widen, resulting in a sudden feeling of pain, Goldberg told Live Science. The researchers said they suspect that an increase in pressure within the skull, brought on by increased blood flow to the head, is what causes the pain.Īnother possible explanation for brain freeze is that a cold sensation activates an important nerve in the head and face, known as the trigeminal nerve. The study found that when patients' brain freeze ended, the artery constricted and reduced blood flow, which is likely what caused the pain to disappear. A small study presented in 2012 found that the sudden increase in blood flow and resulting increase in size of the anterior cerebral artery, a blood vessel located in the middle of the brain behind the eyes, may be responsible for brain freeze pain.
