Teaching overview

Learning points

  • When we eat or drink something cold, it can cause nearby blood vessels to shrink.
  • Additional blood is sent to the head, which causes the blood vessels to expand again, causing a painful sensation.
  • The brain misinterprets the pain signal as coming from the forehead or temples, which results in a type of headache known as brain freeze.
