Ice Cream Headache, or "brain freeze" to kids, comes within seconds of scoffing cold foods or drinks and peaks half a minute to a minute later. As many as a third of the population have felt its "stabbing or aching pain," usually midfrontal but sometimes in the eyes and teeth. This probably makes it the world's leading cause of head discomfort!
Various ICH researchers applied crushed ice to the roof of the mouth (palate) and found touch points which triggered head pain. Hot weather was necessary.
Since touching the back of the palate produces this "referred pain," avoiding such contact will eliminate symptoms, says Hulihan. Nobody's recommending giving up ice cream!!
