Why do we get a "brainfreeze" after we drink a icee really fast?

Answer 1

Your head gets too cold from the ice in the drink and even though your brain is not literally freezing, your head is cold enough to affect nerve endings and cause the sensation.

Answer 2

The cause is a dilation of blood vessels in the head. The dilation may be caused by a nerve center located above the roof of your mouth -- when this nerve center gets cold, it seems to over-react and tries to heat your brain. Therefore, the easy way to avoid "brain freeze" is to keep cold things away from the roof of your mouth!

Answer 3

Am I the only person on the planet that has never experienced this sensation? I can eat frozen stuff fast and never get a brain freeze.

Answer 4

Your body gets cold on a hot day here is in excerpt:
"One interesting part of this is the way that your body reacts to the cold. When your body get cold, the blood vessels in your hands and feet get smaller, so they get less blood. This makes them even colder! Why? Less blood to your hands and feet means more blood to keep your vital organs warm. As you get colder and colder, more and more of your blood is sent towards your brain and vital organs. Less and less goes to the rest of you. Knowing this can help you. If your feet are cold, put on a hat. This keeps your brain warm, meaning more blood for your feet and they stay warmer."

Answer 5

I was always told that the arteries in your neck get too cold from being over exposed to coldness at once.

Answer 6

because as it goes down your throat it makes the arteries that go to your brain cold and as the cold blood travels to the brain instant brain freeze, drink something room temp and it subsides

Answer 7

the nerve endings in your head are affected by the cold generated in your mouth

Answer 8
