    I do not buy the “yawning cools the brain” theory.
    Even we yawn for a long time, the cooling won’t be significant.
    Plus: Yawning is more than common in animals. All animals yawn. Fish yawn too, and their brain will be at sea temperature no matter what. Even sponges do yawn. And they do not have a brain to cool down in the first place.
