On a hot day when you eat a snow cone, the cold crushed ice that touches the top of your mouth initiates a nerve reaction that swells blood vessels in your head. The nerve center on the roof of your mouth overreactsto the cold temperature of the snow cone and tries to heat your brain. This swelling of blood vessels is what causes an ice cream headache, or what is more commonly known as "brain freeze" or "frozen brain syndrome."

Luckily the intense stabbingpain in your head usually lasts only for about 30-60 seconds.

I scream, you scream, we all scream ice cream HEADACHE! - 30% of the human population suffers from these excruciatingheadaches. The best way to avoid getting an ice cream headache is keep the chilled foods or beveragesyou eat on the side of your mouth, away from the roof of your mouth.
