Biology Interview Question:

What is a brain freeze?

Submitted by: Administrator

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.
