What is vasovagal yawning?

If you yawn too much, this may be a sign of a vasovagal reaction--also known as vasovagal syncope, a common cause of fainting. The vagus nerve is located in your neck, chest and intestines. It regulates your heart and blood vessels. When it is stimulated, you begin to yawn excessively.


What happens during a vasovagal episode?

Your heart rate slows, and the blood vessels in your legs widen (dilate). This allows blood to pool in your legs, which lowers your blood pressure. Combined, the drop in blood pressure and slowed heart rate quickly reduce blood flow to your brain, and you faint.

What triggers vasovagal response?

The vagal response (vasovagal reflex) is when stimulation of the vagus nerve causes symptoms such as lightheadedness, sweating, and blurred vision. This can happen because of stress, pain, heat, having a bowel movement, or even standing too long.


How do you fix a vasovagal response?

How is vasovagal syncope treated?
  1. Avoiding triggers, such as standing for a long time or the sight of blood.
  2. Moderate exercise training.
  3. Discontinuing medicines that lower blood pressure, like diuretics.
  4. Eating a higher salt diet, to help keep up blood volume.
  5. Drinking plenty of fluids, to maintain blood volume.


Is yawning a vagus nerve response?

Excessive yawning can be related to the vagus nerve, which runs from the bottom of the brain down to the heart and stomach. In some cases, excessive yawning may indicate bleeding around the heart or even a heart attack. Other symptoms that may indicate a heart problem include: pain in the chest.


What is Vasovagal Syncope and why it occurs?



Is yawning due to a lack of oxygen to the brain?

Scientists used to think we yawn due to a lack of oxygen. But more recent research in the 1980s disproved this theory since breathing in more oxygen or carbon dioxide didn't affect how often one yawns.

How do you reset your vagus nerve?

Some of the most popular ones feature simple hacks to “tone” or “reset” the vagus nerve, in which people plunge their faces into ice water baths or lie on their backs with ice packs on their chests. There are also neck and ear massages, eye exercises and deep-breathing techniques.

Why did I suddenly develop vasovagal syncope?

Vasovagal syncope happens when you have a sudden drop in blood pressure, which causes a drop in blood flow to your brain. It often occurs after standing for a while or under emotional distress. Normally, when you stand up, gravity makes blood settle in the lower part of your body, below your diaphragm.

After an episode of vasovagal syncope, many people will feel nauseous, dizzy, and extremely tired for a few hours. Sometimes these symptoms can last for a day or even longer. Until these symptoms disappear, you are at risk of fainting again.


What are the warning signs of vasovagal syncope?

In most cases of vasovagal syncope, you have some warning that you are near fainting. These signs include dizziness, feeling hot or cold, nausea, pale skin, "tunnel-like" vision, disturbance of hearing, and profuse sweating. After the episode, symptoms may continue because of continued low blood pressure.

Is there a way to prevent vasovagal response?

Preventing a vasovagal syncope includes avoiding any potential triggers, such as standing for a long time or the sight of blood; drinking plenty of fluids to maintain adequate blood volume; and standing up slowly from a lying or sitting position to prevent orthostatic hypotension.

What aggravates the vagus nerve?

There are two main causes of vagus nerve dysfunction: previous infection or inflammation and physical or psychological stress.


Can dehydration cause vasovagal?

Vasovagal syncope — the common faint — occurs in one third of the population. It is by far the most common form of reflex syncope. Vasovagal syncope is often triggered by a combination of dehydration and upright posture. But it can also have an emotional trigger such as seeing blood ("fainting at the sight of blood").

Is vasovagal syncope a heart condition?

Vasovagal syndrome is a heart condition that can cause a sudden, rapid drop in heart rate and blood pressure, which leads to fainting. The condition may also be described as a vasovagal or neurocardiogenic syncope, or vasovagal attack.

What is the number one cause of syncope?

It most often occurs when blood pressure is too low (a condition called hypotension) and the heart doesn't pump enough oxygen to the brain. It can be harmless or a symptom of an underlying medical condition.


At what age group do vasovagal faints commonly occur?

Conclusion: The most common age at which vasovagal syncope first presents is 13 years, and patients remain at risk of syncope for many years. Lifelong coping strategies may be desirable.
