In response to a previous comment of: “Actually, we know why we yawn: it is to reverse the atelectasis of alveoli and to push more surfactant into the alveoli by the type II pneumocytes.” My reply: I don’t think so. This reply may be and in fact is quite likely why we “sigh” but not yawn.

Just drink oxygenated water. You know the brain needs glucose, oxygen and water. Or drink a cup of hot cereal (especially cereal with glucose).

I have often thought that yawning might have something to do with getting focused, mainly because when I’m really nervous, I tend to yawn a lot. Anyone else?

The word “yawn” has officially lost all meaning to me after all this repetition!
