Brain freeze, or an ice-cream headache (a.k.a. sphenopalatine ganglioneuralgia, if your tongue isn’t too cold to get you past that mouthful), is a real thing and it happens when you eat or drink something ice cold way too fast.
Your blood vessels react instantly by constricting, but your body’s also trying to dilate them to warm up the area. The resulting temperature war sends a message to your confused brain: pain!
But it’s easily fixed: swallow the ice cream, press your tongue to the roof of your mouth to warm it up, let the hurting stop and move on to the next spoonful. Slowly does it, this time round.
Good to know right? Put the theory to the test.
