After seeing recent Pepsi Max commercials, my colleagues and I opened up that age-old discussion on why people yawn, and why is it contagious. I saw this news special and thought I’d share. Supposedly yawning cools our brain and can be prevented w/ a cold compress or by breathing through our nose which is a natural brain coolant.

Why People Yawn

Next time your friend is yawning, consider it a compliment that you really have their brain working and they need to cool it off.
