2. Minor Causes of Excessive Yawning

Most cases of excessive yawning occur as a result of trivial events. Some individuals yawn when they are bored or disinterested in what they're doing. Sleepiness causes excessive yawning, as does poor sleep patterns, some medications, and even cooler temperatures. These reasons usually resolve themselves when individuals become aware of the problem and make the necessary lifestyle changes.
