Why do I yawn every 2 minutes?
Although excessive yawning is usually attributed to being sleepy or bored, it may be a symptom of an underlying medical problem. Certain conditions can cause a vasovagal reaction, which results in excessive yawning. During a vasovagal reaction, there’s increased activity in the vagus nerve.
