This condition is caused by various reasons, such as boredom, sleepiness, or stress. Excessive yawning can also be caused by an underlying medical condition, such as sleep apnea, anxiety, or depression. Doctors may refer to this condition as yawning a lot, too much yawning, or severe yawning.

Anxiety is a common trigger for yawning. Anxiety affects the heart, respiratory system, and energy levels. These can all cause breathlessness, yawning, and feelings of stress.

Just getting in position to yawn can be enough to prompt an actual yawn to form. Tighten the muscles at the back of your throat. These muscles naturally contract a little when you yawn. Contracting them now may stimulate your body to form a real yawn.

There's little evidence to suggest that excessive yawning is caused directly by a vitamin deficiency. However, some vitamin deficiencies may cause fatigue, which often involves yawning. Not getting enough vitamin B12, for example, can lead to vitamin B12-deficiency anemia, which may lead to feeling fatigued.
