A cold-stimulus headache, colloquially known as an ice-cream headache or brain freeze, is a form of brief pain or headache commonly associated with consumption (particularly quick consumption) of cold beverages or foods such as ice cream, popsicles, and snow cones. It is caused by a cold substance touching the roof of the mouth, and is believed to result from a nerve response causing rapid constriction and swelling of blood vessels,[3] "referring" pain from the roof of the mouth to the head.[4][5] The rate of intake for cold foods has been studied as a contributing factor.[1][6] It can also occur during a sudden exposure of unprotected head to cold temperatures, such as by diving into cold water.[7] A cold-stimulus headache is distinct from dentin hypersensitivity, a type of dental pain that can occur under similar circumstances.

Cats and other animals have been observed exhibiting a similar reaction when presented with a similar stimulus.[8]
