All About Brain Freeze: Here’s Why We Get The Ice Cream Headache

What’s the best way to stop a brain freeze?

You want to bring the temperature of your mouth back up to normal, so the blood vessels can shrink back to their neutral state. One proven way to do so is to press your tongue against the top of your mouth, where its heat will transfer into the tissue. Similarly, you can drink room-temperature water, which serves the same function.But even if you don’t do either of those things, brain freeze typically lasts a few seconds to a few minutes, and it’s not dangerous — certainly not dangerous enough to deny ourselves the pleasure of ice cream.
