Yawning (Overview)

Yawning is opening the mouth semi-voluntarily while taking a long, deep breath of air. It is a type of reflex action controlled by the brain (a person cannot yawn on command). Yawning is normal, and usually due to drowsiness or tiredness. However, excessive yawning that happens much more often than normal may be caused by vagus nerve signals, due to some medical problem.
