why do you get a headache after eating ice cream
Cold-stimulus headache A cold-stimulus headache, also known as brain freeze, ice-cream headache, trigeminal headache[1][2] or its given scientific name sphenopalatine ganglioneuralgia (meaning "pain of the sphenopalatine ganglion"), is a form of brief pain or headache commonly associated with consumption (particularly quick consumption) of cold beverages or foods such as ice cream and ice pops. It is caused by having something cold touch the roof of the mouth, and is believed to result from a nerve response causing rapid constriction and swelling of blood vessels[3] or a "referring" of 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.[6][7] A cold-stimulus headache is distinct from dentin hypersensitivity, a type of pain that can occur under similar circumstances.
Neapolitan ice cream Neapolitan ice cream was named in the late 19th century as a reflection of its presumed origins in the cuisine of the Italian city of Naples, and the many Neapolitan immigrants who brought their expertise in frozen desserts with them to the United States. Spumone was introduced to the United States in the 1870s as Neapolitan-style ice cream. Early recipes used a variety of flavors; however, the number of three molded together was a common denominator, to resemble the Italian flag (cf. insalata tricolore). More than likely, chocolate, vanilla, and strawberry became the standard for the reason that they were the most popular flavors in the United States at the time of introduction.[3]
