Did You Know?
The scientific term for brain freeze is “sphenopalatine ganglioneuralgia”.
You’ve probably experienced that unpleasant feeling commonly referred to as brain freeze, ice cream brain, or an ice cream headache. This sensation, which can cause a short-term headache lasting from a few seconds to a few minutes, may happen when you eat or drink something cold, like ice cream or ice water. The medical term for brain freeze is sphenopalatine ganglioneuralgia. You may also hear this sensation referred to as cold-induced headache.
Brain freeze is caused by the sphenopalatine ganglioneuralgia nerves (SPG), which is a group of nerves near the trigeminal nerve in the brain. These nerves are located behind the nose and the nerves that also cause headache pain. They are designed to be highly sensitive to pain, presumably to protect the brain.
