Why does eating ice cream too fast hurt your brain?

Answer 1

because all the cold ice cream hits the back of your mouth really fast See below. An ice-cream headache, also known as brain freeze, cold-stimulus headache, cold headache, or its given scientific name sphenopalatine ganglioneuralgia (meaning "nerve pain of the sphenopalatine ganglion"), is a form of brief cranial pain or headache commonly associated with consumption (particularly quick consumption) of cold beverages or foods such as ice cream. It is caused by having something cold touch the roof of the mouth (palate), and is believed to result from a nerve response causing rapid dilation and swelling of blood vessels or a "referring" of pain from the roof of the mouth to the head. The rate of intake for cold foods has been studied as a contributing factor.
it doesn't besause the roof of your mouth has senstive nerves so when you taste something cold it sends it through the nerves to tell you its cold try putting ur thumb and push on the roof of your mouth
When something cold touches the center of the palate, the cold temperature can set off certain nerves that control how much blood flows to your head. The nerves respond by causing the blood vessels in the head to swell up. This quick swelling of the blood vessels is what causes a headache.
