Brain Freeze
Eat something cold and what happens? Brain Freeze!
Noone really knows why but scientists think Brain Freeze occurs when the temperature of your palate doesn't have enough time to normalize between spoonfools of cold. The capillaries in the roof of the mouth dilate rapidly, filling with warmth inducing blood, and that sudden expansion could trigger nerves at the back of your palate to fire off urgent messages to your brain. In response, blood vessels in your forehead swell in a pattern that resembles a migrane.
To cure a Brain freeze, press your tongue hard against the palate to thaw it quickly, or breathe into your hands to heat your mouth.
