Why Do People Get 'Brain Freeze' from Cold Drinks?

Brain freeze happens when you drink something super cold, like ice cream or a slushie. Your mouth gets really chilly, and that sends a message up to your brain, whoosh!, and your brain thinks it's being attacked by an icy enemy. It tries to protect itself by sending blood rushing to the front of your head, which makes you feel like your head is about to burst. But don't worry, it only lasts for a few seconds!
