Nothing slows an ice cream enthusiast like an onslaught of brain freeze, or sphenopalatine ganglioneuralgia. Ever wondered why your favorite frozen dessert leaves you scrunching your face in pain? The answer is simple.

Located at the roof of your mouth are a cluster of nerves. When something cold touches it, the blood vessels shrink and then expand as blood rushes back into your mouth to warm it up. As a result, you get the sensation of having a headache. Brain freeze is most likely to occur in warm weather.

The cure? Try to avoid contact between the roof of your mouth and ice cream as much as possible.
