Brain freeze is practically a rite of summer. It happens when you eat ice cream or gulp something ice cold too quickly. The scientific term is sphenopalatine ganglioneuralgia, but that’s a mouthful. Brain freeze is your body’s way of putting on the brakes, telling you to slow down and take it easy. – Dwayne Godwin, Ph.D., neuroscientist at Wake Forest Baptist Medical Center
Turns out, you are rapidly changing the temperature at the back of your throat when you are slurping down something cold too fast, and that is where the juncture of the internal carotoid artery (feeds blood to the brain) and anterior cerebral artery (where your brain tissue starts) is.
Essentially, your brain is telling you to stop doing that because your brain doesn’t like change! And while your brain can’t actually feel pain, your brain interprets the rapid dilation and contraction of those arteries as pain.
A quick fix for a brain freeze?
Jam your warm tongue up the roof of your mouth to normalise the temperature of your mouth or drink something warm!
