BrainFreeze

Brain Freeze is a term used to describe a headache or a throbbing pain felt after consuming cold beverages or foods such as ice-creams. The chances of this happening is increased as rate of consumption is increased.

The scientific term for Brain Freeze is Temporal Neurocranial Vasodilation.

When cold food touches the roof of the mouth, or anywhere near the Parotid gland, the Sphenopalatine Ganglia nerves there are triggered. They send a signal to the brain that it is in a very cold environment. Homeostatic functions are induced. Negative feedback causes the blood vessels in the brain to vasodilate and swell for about 30 seconds to provide the brain with the necessary heat. The swell presses against the cranial nerves, inducing pain.

A simple cure to it would be to move your tongue to the roof of your mouth when you suffer from Neurocranial Vasodilation. This would cause greater warmth to the Sphenopalatine Ganglia nerves and thus, they will not send impulses for vessels in the brain to vasodilate.
