What causes brain freeze?
I really hate it when you are right Dillo...Damn it!!
I can't eat Italian ice...cuz, when I do I get brain freeze that seems to last forever...right in my eyes...yuck.
Q: What exactly causes brain freeze? And here’s a better question — how do I prevent it from happening in the first place?
Snip...
ice cream headaches don’t come only from ice cream — they can come from eating any really cold food or drink. Like Slurpees. In fact, in 1994, 7-Eleven even trademarked the term Brainfreeze to use in conjunction with its delicious frosty drink.
So what causes ice cream headaches in the first place? It has to do with the nerve receptors above the roof of your mouth. When you take a bite of ice cream, some of it touches the top of your mouth, otherwise known as the hard palate. That in turn triggers the nerves above the palate to cool down — and quick. The nerves send an emergency message to the brain that it’s about to get cold up there, and the blood vessels in the brain constrict to accommodate. When the warm blood rushes through the blood vessels again — presto! You get a searing headache similar to a migraine. Ouch! But don’t worry though, this kind of headache does not signify a serious problem.
