Oh Lord, it's c-c-c-cold

 With outside temperatures hovering in the balmy 10° - 14° range this week, thoughts turn to ice cream and that traditional Baltimore favorite, the snowball (known in some areas as a sno-cone).

Whatever your pleasure, be it frozen milk or cream or just good ol' ice, shaved to bits and doused with flavored syrup (make mine egg custard, please), cold treats require proper mouth management, or you will suffer the heartbreak known as "brain freeze" or "ice cream headache."

The reason this happens is that your brain has very little idea what the heck you are up to. It spends its days trying to maintain a nice core temperature for you, and you treat it like this? For shame.

Because, dunking ice or ice cream on the roof of your mouth sends a signal to your brain..."Hey! It's cold in here!"

In turn, your brain tells the blood vessels in your head to constrict, in an effort to maintain a robust core temperature. This is called a "survival reflex," like when you're flipping around on the TV and land on a channel showing nature films or Harry Potter or Snoop Dogg E. Dogg. You can't change the channel fast enough, and that's what your blood vessels do...they get smaller until the cold goes away.

However, there's this. You can now call out sick from work or blind dates just by claiming you've come down with a bad case of “sphenopalatine ganglioneuralgia.” That's doctor talk for brain freeze.

Take two aspirins and call me in the morning.
