Imagine your mouth is like a cold room. When you drink ice water, it cools down the roof of your mouth really fast. This sends a message to your brain that says, 'It’s super cold!' Your brain gets confused and thinks something is wrong, which makes your head hurt, just like when you get a surprise.
Examples
- Drinking a big glass of ice water on a hot day can cause your head to hurt like it's been hit with a snowball.
- Eating an ice cream cone too fast might make you feel like your brain is freezing over.
- Sipping ice water through a straw makes the cold go straight to your forehead, and then your whole head.
