Brain freeze

From Academic Kids

Brain Freeze or ice cream headache are term used to describe a form of cranial pain or headache which human beings are known to sometimes experience after consuming cold beverages or foods such as ice cream, often as a result of consuming at a high rate of speed.

In rare instances, neuro-cranial blood vessels can constrict so completely that a temporary blackout can occur.

Mechanism/Cause

The reaction is triggered by the cold from the substance consumed coming into contact with the roof of the mouth while the individual eats it. It triggers nerves that give the brain the impression of a very cold environment. To return warmth to the brain, blood vessels start to swell, which causes the pain for, typically, around 30 seconds.

It is reported that pain can be relieved by moving the tongue to the roof of the mouth, which will cause greater warmth in the region. he:קיפאון מוחי

A paper was submitted to the British Medical Journal on Brain Freeze. It focused on the effect of speed of consumption of ice cream on causing Brain Freeze. It was co-written by a Canadian grade 8 student (about 13 years old).
