When you eat or drink something extremely cold, especially on hot days you can get brain freeze/ ice cream headache etc. Scientist 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. tissue stimulates nerves to cause rapid dilation and swelling of blood vessels. Thus, an attempt to direct blood to the area and warm it back up very quickly. the effect can be painful for a short period of time, but there's no danger
