...what do you mean you feel it in your forehead? like it gets cold or something?...

yes, and it hurts like a headache. it also happens when i eat ice-cream.

Hmmm... I don't know why that is, but maybe you should stop breathing in cold air.

It affects nerves on the top of your mouth which causes that headache sensation. Try to warm the air b4 breathing.

When something very cold touches the center of the palate, the cold temperature can set off certain nerves, just as mithrilhack said, that controsl how much blood flows to your head. The nerves respond by causing the blood vessels in the head to swell up. This quick swelling of the blood vessels is what causes your head to pound and hurt. Some people call this a "brain freeze," even though nothing is really happening in the brain - it's all in the blood vessels of the head.

I've heard of this... I never experienced it. I went ice fishing this winter and it was -15 celsius and still i didn't feel anything
