What causes brain freeze?

Answer 1

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.

Answer 2

The reaction can sometimes be triggered within a few seconds after a very cold substance consumed comes into contact with the roof of the mouth. The pain is not caused by the cold temperature alone, rather quick warming of the hard palate. Letting the mouth slowly adjust back to normal temperatures can prevent this from occurring. Brain freeze is often a result of speaking or breathing out of the mouth after consuming something cold. The body's response to cold environments is to vasoconstrict the peripheral vasculature (to reduce the diameter of blood vessels). This vasoconstriction is in place to reduce blood flow to the area, and thus minimize heat loss to keep warmth in the body. After vasoconstriction, they return to normal status and artery size results in massive dilation (vasodilation) of the arteries that supply the palate (descending palatine arteries).

Answer 3

Brain freeze

Eating ice cream too fast !

When cold stuff (like popsicles, ice cream or slushies) touches the roof of your mouth it can set off a nerve reaction (in the spheno-palantine ganglion, to be precise), that causes the blood vessels in your brain to swell. When the blood vessels swell, you get a headache

Answer 4

I always thought a brain freeze occurred when you ate something cold, like ice cream too fast and your nerves couldn't process the information quick enough. So your nerves got an overload of information.

Answer 5

when ur arteries in ur head get to cold and expand and contract very fast. to get rid of a brain freeze u should put ur tongue on the roof of your mouth so it warms the arteries up.
