LinkWe yawn because your body needs oxygen and a yawn is basically a big breath.

LinkThe most recent research on yawning suggests that it exists to cool down the brain. That open-mouthed yawn causes sinus walls “to expand and contract like a bellows, pumping air onto the brain, which lowers its temperature,” National Geographic reported.
