cream to eat mostly experience brain freeze. 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. 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.
