No, I promise, you are NOT boring me. I’m just hot.
What you say? What kind of baloney is that?
Sorry, though, it’s true. The data are now indicating that we yawn to cool our brains. Dr. Andrew Gallup (Princeton University) has been studying the effects of yawning on thermoregulation since 2009, when he was at SUNY Binghamton. (You’ll see how my brain gets cooled below, when I describe where I sit.)
