text: The action of yawning also has the effect of stretching the eardrums and opening the Eustachian tubes to the ears (which is why a yawn often serves to “unpop” ears popped due to pressure changes), and it is usually accompanied by characteristic motions, such as a throwing back of the head and a squinting or closing of the eyes.
