We yawn mostly when we’re tired and bored. Yawning is useful for alleviating pressure in your eardrums, but we yawn usually because we feel drowsy. Yawning excessively can be felt when the act of yawning occurs repeatedly or in close succession that is more than few times per minute.

Excessive yawning, on the other hand, could be a symptom of a serious health issue. Some medications, such as those used to treat depression, pain, anxiety or allergies, can cause excessive yawning too. Now here are some of the reasons to know why we yawn too much.
