Eating shaved ice sometimes gives me a headache. Why?
Not just ice cream, but other cold foods too. This is a series of chain reactions that occur after extremely cold food or drinks come into contact with the base of the tongue. It is medically known as "ice cream headache". It is usually located in the middle of the forehead. It usually occurs a few seconds after eating a cold drink quickly. 30- The pain reaches its peak at 60 seconds, and there are also a few cases of longer duration; there are occasional reports of epilepsy induced by eating cold drinks. Ice cream headaches are more likely to occur in summer when the climate is hot than in winter. Some theories believe that large amounts of cold food cause the capillaries in the sinuses to rapidly contract and relax, stimulating pain receptors and triggering trigeminal neuralgia. There is also a theory that low-temperature food causes the blood vessels in the maxilla to constrict. The pressure receptors on the blood vessel walls inform the brain of this change. In order to ensure the blood supply to the brain, the human body reflexively increases the amount of blood entering the brain from the anterior cerebral artery, causing pain. Are migraine sufferers more likely to get ice cream headaches? There is still controversy in the medical community.
