Think you can last against the Yawn-O-Meter? Give it a try, but don’t blame me if you spend the next ten minutes yawning a whole bunch. Or do, because it’s basically all my fault. It’s also AsapSCIENCE’s fault, but at least they’ll teach you why you yawn (or the best explanation we currently have) in return.
As the video points out, while it’s commonly believed that yawning is to draw in more oxygen, new information suggests that old theory isn’t really correct:
The brain cooling theory has some pretty good support in with the hot water/cold water bottle experiment, but I still have a personal theory that a yawn isn’t any different from any other stretch you do when you’re tired; it’s just for your face and throat muscles as opposed to stretching your arms. Hey, maybe it’s both?
Too bad science is too busy curing diseases and saving us from asteroids to find out.

- Science is also too busy building stripper robots
- And wearable electronic underwear
- But at least it can explain your body’s reaction to spicy foods
