Science Mysteries: Why Do People Yawn?


Recent studies suggest that we yawn when we get tired as a way to encourage our brains. The theory is that yawning helps cool the brain, allowing it to work more efficiently. According to WebMD's article about these studies, when you yawn, your jaw muscles get stretched, increasing blood flow to your neck, face, and head. Also a deep breath during the yawn forces spinal fluid and blood down from the brain. The cool air then cools down these fluids.

Mark'd how, to explore the vacant, vast surrounding,
It launch'd forth filament, filament filament, out of itself,
Ever unreeling them-ever tirelessly speeding them.
And you, O my Soul, where you stand,
Surrounded, surrounded, in measureless oceans of space,
Ceaselessly musing, venturing, throwing.-seeking the spheres, to connect them;
Till the bridge you will need, be formid-till the ductile anchor hold;
Till the gossamer thread you fling, catch somewhere, O my Soul.
