What Is Excessive Yawning?
Yawning excessively is a condition where a person yawns more often than normal. 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.

Excessive yawning reasons include:
- Physical Causes—Fatigue, general tiredness, body temperature malfunctions, and stimulation of the vagus nerve can cause frequent yawning. Excessive yawning and sleep disorders are often correlated.
- Emotional Causes—Anxiety and depression can lead to yawning excessively.
- Medication—It is rare for medications to trigger yawning.
- Life-Threatening Causes—Strokes and tumors can cause regular yawning.
- Certain Neurological Disorders—ALS, Parkinson’s disease, multiple sclerosis, epilepsy, stroke, narcolepsy, or frontal lobe or brain stem tumor.
There has been some speculation regarding other causes for excessive yawning, such as vitamin deficiencies, changes in blood pressure, or changes in oxygen levels.

Some have theorized that excessive yawning may be due to a vitamin deficiency. Currently, there is no scientific evidence that indicates excessive yawning is due to a vitamin deficiency. However, there are certain vitamin deficiencies that cause fatigue, which may lead to yawning. Being low in B12 may cause B12-deficiency anemia, which may cause fatigue. Iron deficiency may also cause fatigue and lead to yawning.
Scientific evidence has not pointed specifically to a lack of oxygen as being a cause of excessive yawning. However, some medical conditions that contribute to a reduction in blood oxygen saturation, such as sleep apnea, have been known to cause excessive yawning. Sleep apnea occurs when there is a narrowing of the airway when you try to breathe in, or when your brain fails to send appropriate signals to your breathing muscles. Both forms of sleep apnea can lower oxygen levels in the body and may lead to fatigue and yawning.
Vasal vagal syncope is another medical condition that may induce yawning. This condition occurs when your blood pressure and heart rate drop rapidly, causing you to faint or pass out. It typically only happens while standing or sitting. One of the symptoms of vasal vagal syncope is yawning.

Emotional or psychological symptoms of yawning excessively:
- Frustration—You might feel aggravated by constant yawning.
- Anxious—If you find yourself unable to stop yawning, you can feel anxious or worried.
- Boredom—When bored, your body lapses into a low-activity state. Yawning is your body attempting to wake you up.
Anxiety often causes the body to feel keyed up or on edge, which is due to an activation of the sympathetic nervous system, and allows your body to be ready to respond to a threat or any perceived threat. Conversely, for your body to regulate during times of threat or perceived threat, it engages the parasympathetic nervous system, which allows your body to feel calm and safe. Yawning is characterized as a function of your parasympathetic nervous system, and it helps your body to feel calmer and more regulated.
Certain medications used to treat anxiety have also been known to cause fatigue and more frequent yawning.
Severe or life-threatening symptoms of yawning excessively:
- Heart problems—If yawning excessively is accompanied by chest pain or an irregular heartbeat, it could be a sign of a heart condition.
- Stroke—Sudden, severe yawning could be a warning sign of an impending stroke.
- Brain tumor—In rare cases, yawning excessively can be a symptom of a brain tumor.
