Cold Bites Trigger 20-30 Second Forehead Pain as Mouth Blood Vessels Rapidly Constrict and Dilate

Brain freeze peaks within 20 to 30 seconds because extreme cold hitting the roof of the mouth makes blood vessels in the sphenopalatine ganglion clamp down, then quickly widen as warm blood rushes back.
That rapid vascular swing triggers pain, but the brain misplaces it in the forehead: the ganglion sits near the trigeminal nerve, so the signal is read as coming from the temples or brow rather than the mouth.
Pressing the tongue to the roof of the mouth or drinking something warm can shorten the episode by reheating the sensitive area directly.
Migraine sufferers tend to get stronger, more frequent brain freeze, and researchers use the harmless reaction as a repeatable way to study vascular headache pathways.
Could the nerve behind an 'ice cream headache' be the key to a new generation of migraine treatments?
With new IV drugs for migraines, could an instant cure for the common brain freeze be next?
Does your frequent brain freeze signal a hidden risk for developing chronic migraines?
