@doomsdayrs Feel the roof of your mouth with your tongue after you yawn - it will be a little bit cool to the touch, because of its thermal conductivity.

Also, if you have a yawn attack, but are not sleepy - eat something cold, like ice cream.

This is according to the University of Albany research.

@doomsdayrs probably, to regulate brain temperature. There is a theory on yawning that its purpose may be brain cooling. So, the roof is basically a thermal interface.
