Answer 2

Answer:

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.
