A yawn is a reflex of deep inhalation and exhalation of breath. Yawning is associated with tiredness, stress, overwork, lack of stimulation, or boredom.
There are many parts of the body that are in action when you yawn. First, your mouth opens and jaw drops, allowing as much air to be taken in as possible. When you inhale, the air taken in is filling your lungs. Your abdominal muscles flex and your diaphragm is pushed down. The air you breath in expands the lungs to capacity and then some of the air is blown back out.

If you don't cover your mouth while yawning, then the devil will come and steal your soul (Estonia).

The Ancient Greeks believed that yawning was not a sign of boredom, but that a person's soul was trying to escape from its body, so that it may rest with the gods in the skies.
