Ice Cream Headache
Did you know that the painfully familiar “brain freeze” actually has a scientific name? Some people call it an ice cream headache, but doctors use the term sphenopalatine ganglioneuralgia. This sharp, sudden headache happens when something very cold hits the roof of your mouth. Your body reacts by quickly changing the size of blood vessels, sending a pain signal to your head—brief, surprising, but completely harmless.
To ease it, just warm your mouth—sip room-temperature water or press your tongue or thumb gently to the roof of your mouth, and it usually melts away in seconds. Share your own “brain freeze” stories in the comments!
