Everybody yawns — from unborn babies to the
oldest great-grandparent. Animals do it, too. But
why, exactly, do people and animals yawn? No one
knows for sure. But there are many theories (ideas)
about why people yawn.
One is that when we are bored or tired, we just don't
breathe as deeply as we usually do. As this theory
goes, our bodies take in less oxygen because our
breathing has slowed. Therefore, yawning helps us
bring more oxygen into the blood and move more
carbon dioxide out of the blood.
Yawning, then, would be an involuntary reflex
(something we can't really control) to help us control
our oxygen and carbon dioxide levels. Sounds good,
but other studies have shown that breathing more
oxygen does not decrease yawning. Likewise,
breathing more carbon dioxide does not increase
yawning. Hmmm. Now what?
Another theory is that yawning stretches the lungs
and lung tissue. Stretching and yawning may be a
way to flex muscles and joints, increase heart rate,
and feel more awake.
Other people believe that yawning is a protective
reflex to redistribute the oil-like substance called
surfactant (say: sur-fak-tint) that helps keep lungs
lubricated inside and keeps them from collapsing.
So, if we didn't yawn, according to this theory,
taking a deep breath would become harder and
harder — and that would not be good!
But there is one idea about yawning that everyone
knows to be true. It seems contagious. If you yawn in
class, you'll probably notice a few other people will
start yawning, too. Even thinking about yawning can
get you yawning. How many times have you yawned
while reading this article? We hope not many!

op you are very correct, sometimes i thought there is apiritual meaning to it. when someone in front of me yawn,i will also yawn authomatically. i have been thinking about these for a long time also.
