Why Do I Get a Headache When I Eat Something Cold?

Cold foods trigger headaches through sphenopalatine ganglioneuralgia, commonly known as "brain freeze." This occurs when cold substances contact the roof of your mouth, causing blood vessels in your head to rapidly constrict and then dilate. The trigeminal nerve, which controls sensation in your face, sends pain signals to your brain within 10-20 seconds of cold exposure. About 37% of people experience these headaches regularly. Ice cream, frozen drinks, and popsicles are common triggers. The pain typically peaks within 25-60 seconds and resolves quickly. Eating cold foods more slowly or warming them slightly in your mouth before swallowing can prevent these headaches.
