Yawning involves opening the mouth involuntarily with a prolonged, deep inhalation of air, as from drowsiness or weariness.
Yawning is a normal response to fatigue and drowsiness, but excessive yawning can be caused by a vasovagal reaction and may indicate a heart problem.
Normal yawning may be induced when the brain or lungs are not getting enough oxygen (or when someone else yawns).
