Read this without yawning…

Why do people yawn? The most common belief is that yawning helps increase oxygen supply to the brain even though there is absolutely no association between yawning and blood oxygen levels. The latest research shows that yawning regulates the temperature of the brain. Who’d a thunk that? So many things affect brain temperatures, from sleep cycles, to cortisol levels, stress and even arousal cause fluctuations in brain temperature. Yawning effectively helps keep the brain temperature in optimal homeostasis to improve alertness and mental efficiency. Yawning is also affected by ambient temperature variations. Contagious yawning occurs more in the summer than in the winter – unless you live in Arizona like I do where the temperature in the summer goes above the more-yawning frequency range which lies between the temperatures of 68 and 98 degrees F.

Makes me want to yawn just thinking about it.
