Brain Freeze – Louis

  1. Brain freeze, also known as an ice-cream headache, cold-stimulus headache, or sphenopalatine ganglioneuralgia, is a kind of short-term headache typically linked to the rapid consumption of ice-cream, ice pops, or very cold drinks.
  2. They found that the sensation of brain freeze appears to be caused by a dramatic and sudden increase in blood flow through the brain’s anterior cerebral artery. As soon as the artery constricted, the brain-freeze pain sensation wore off.

  4. When something cold touches the roof of your mouth (your palate), the sudden temperature change of the tissue stimulates nerves to cause rapid dilation and swelling of blood vessels. This is an attempt to direct blood to the area and warm it back up.
  5. The dilation of the blood vessels triggers pain receptors, which release pain-causing prostaglandins, increase sensitivity to further pain, and produce inflammation while sending signals through the trigeminal nerve to alert the brain to the problem. Because the trigeminal nerve also senses facial pain, the brain interprets the pain signal as coming from the forehead. This is called ‘referred pain’ since the cause of the pain is in a different location from where you feel it. Brain freeze typically hits about 10 seconds after chilling your palate and lasts about half a minute. Only a third of people experience brain freeze from eating something cold, though most people are susceptible to a related headache from sudden expo
