So what actually causes brain freeze? Researchers suggest it is a combination of your body's overreaction to cold stimuli, freezing of a cluster of nerves above the palate and a sudden influx of warm blood to the brain. Eating all of that ice cream or slushy drink too quickly didn't help matters, either. In fact, it was the initial contact between the cold food and the roof of your mouth which set all of this brain freeze activity in motion.
When you took an extra large bite of ice cream, some of it reached the roof of your mouth, also known as the hard palate. Behind this hard palate lies a cluster of nerves which act as a protective thermostat of sorts for your brain. The main nerve is called the sphenopalatine nerve, and it's extremely sensitive to abrupt changes in temperature. Once the ice cream or other frozen food causes the sphenopalatine nerve to cool down, it sends out a warning to the other nerves in the cluster. Essentially, your brain has now been told to expect a major freeze, so it had better prepare itself.
While all of these blood vessels are busy shrinking and reopening with warm blood, the nerves are also contributing to the pain of brain freeze. The pain receptors near the sphenopalatine nerve cluster sense the freezing of the palate, but the pain itself is referred to another area deeper in the skull. This is why you feel brain freeze deep inside your head and not in the roof of your mouth.

Have you ever wondered why your fingers and toes wrinkle when they're wet?
If you find yourself wearing flip-flops around a pool this weekend, consider this: You may already come equipped with skid-resistant footwear, thanks to evolution. New research suggests that our toes and fingers prune up when they're exposed to water because that temporarily gives us the equivalent of treaded all-weather tires.
