• Brain freeze is an intense stabbing headache-like pain that occurs after consuming something cold, and it affects about 30 percent of the population.
  
• Your brain DOES NOT actually freeze. NO damage is caused by brainfreeze.
  7-Eleven registered the term "brainfreeze" in 1994 to communicate the painful joy of drinking a frozen Slurpee beverage.
  
• Brainfreeze is also known as an "Ice Cream Headache", and "Frozen Brain Syndrome"
  Simply put, Brainfreeze occurs when the Slurpee (or anything cold) touches the roof of your mouth, the collection of nerves in the roof of your mouth (called the spheno-palantine ganglion) go into a spasm (a spasm is like a cramp). These nerves tell the brain blood vessels to get bigger or "dilate". When our brain's blood vessels get big, we get headaches.
  
• The pain of brainfreeze begins a few seconds after the rapid ingestion of cold foods or beverages (such as ice cream or slurpees or yellow snow)and peaks in 30-60 seconds, and can last up to 5 minutes.
  
  
• It is a stabbing or aching type of pain that recedes 10-20 seconds after its onset. Rarely, it can persist for two to five minutes .
