Have you ever taken a huge bite of ice cream and suddenly felt a sharp pain in your forehead? That's called brain freeze. But your brain isn't actually freezing. The extreme cold makes the blood vessels in the roof of your mouth rapidly shrink. Seconds later, they suddenly expand again to restore normal temperature. Those sudden changes activate the trigeminal nerve, one of the largest sensory nerves in your head. Your brain mistakenly interprets the signal as pain coming from your forehead. So brain freeze isn't your brain getting cold. It's your nervous system becoming confused for a few seconds. Once the temperature returns to normal, the pain quickly disappears.
