Yawning - excessive
Definition Yawning involves opening the mouth involuntarily while taking a long, deep breath of air. This is usually done as a result of drowsiness or weariness. Excessive yawning is yawning that happens more often than would be expected, even if drowsiness or weariness is present. Alternative Names Excessive yawning Considerations Yawning is a normal response to fatigue and drowsiness, but excessive yawning can be caused by a vasovagal reaction. This reaction is caused by the action of a nerve, called the vagus nerve, on the blood vessels. It may indicate a heart problem. Normal yawning may happen when someone else yawns.
