What makes you have a brain freeze?

Answer 1

Brain freeze, cold headache, ice cream headache, freezie, Frozen Brain Syndrome, or its given scientific name sphenopalatine ganglioneuralgia are terms used to describe a form of cranial pain or headache which people are known to sometimes experience after consuming cold beverages or foods such as ice cream, slurpees, or margaritas, particularly when consumed quickly

Answer 2

There is a nerve that runs from the roof your mouth pretty much staight to your brain. When something cold hits the roof of your mouth it shoots right up the nerve. If you can keep the cold stuff away from the roof of your mouth you will not get brain freeze.

Answer 3

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 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). The nerves in the region of the palate (greater and lesser palatine nerves) sense this as pain and transmit the sensation of this pain back to the trigeminal ganglia. This results in pain that is referred to the forehead and below the orbit, other regions from which the trigeminal nerve receives sensation (This phenomenon is similar to the pain that is present in the left arm when someone is having a myocardial infarction or heart attack). A similar effect occurs when one takes a prescription vasodilator, such as Nitroglycerin or Viagra. It is a stabbing or aching type of pain that usually recedes within 10–20 seconds after its onset, but sometimes 30–60 seconds, and can persist for up to five minutes in rare cases. The pain is usually located in the midfrontal area, but can be unilateral in the temporal, frontal, or retro-orbital regions.[

Mostly by drinking slurpees, it has happened with water and pop; eating freezes, ice cream, ect. It all depends on how cold it is and if it hits the spot in your mouth to give you brian freeze...

Answer 5

The extreme cold in your sinuses makes the blood vessels contract. Some people get it in their nose, others in their head. Once the vessels warm back up and expand back to normal, that's when brain freeze goes away.

Answer 6

the cold liquid that travels down your esophagus passes by the artery that is heading up towards your brain. when you drink alot in a short amount of time it cools the blood and thus cools the brain.

Answer 7

technically there is no such thing. something that is very cold like something with ice triggers the nerves in your body to do that.

Answer 8

The coldness from whatever your eating or drinking
