Why do you get brain freeze?

Answer 1

Nothing.

Commonly it's a cold headache. Cold Stimulus Headache.

Although we use the term pain for the brain, there is no such thing. The vessels and nerves around the brain are what is causing the "pain" you feel.

Brain freeze is a headache most commonly associated with the quick consumption of cold substances, such as ice cream. When the cold substance comes into contact with your palate or the roof of your mouth and sinus cavities it causes the blood vessels to vasoconstrict or get smaller.

As the palate warms the blood vessels dilate. This rapid constriction and dilation is detected by pain receptors that travel to the brain via the trigaminal nerve, which also serves as one of the major nerves for the facial area. Because the pain signal travels with the signals coming from the face, the brain thinks it is feeling pain in the face that isn't really there, this is called referred pain.

Answer 2

What is commonly referred to as 'brain freeze' occurs when you ingest something that is very cold too quickly. When the cold touches your soft palate it constricts the blood vessels in the area, and then when they dilate it causes pain behind the eyes or even up into the forehead. Your brain does not actually freeze, you just get a lot of pain for a short period of time.
