Stimulation Of The Vagus Nerve In The Ear

Stimulation of the vagus nerve in the ear is a technique used for complex problems such as pain management and to reduce the rate of aging to some extent. It has actually become quite popular in recent times, which is why the number of surveys to validate effectiveness is increasing.

Studies, such as this one conducted by the Technische Universität Wien (Technical University of Vienna), highlight the effectiveness of stimulating the vagus nerve of the ear to relieve chronic pain. The results are very encouraging, but more research is still needed.

In this article, we take a look at what science can tell us so far.

Stimulation of the vagus nerve

How is it that stimulation of the vagus nerve in the ear can affect pain, aging and even issues as complicated as mental health?

This is because there is a link between the location of this nerve, the hearing aid and certain functions in the human body’s systems.

The ear is a gateway to the nervous system. There are specific areas where one can stimulate the vagus nerve, mainly in the outer part of the ear. Because this structure passes through the internal organs, when the information it carries to large parts of the body.

This technique consists of inserting small electrodes, controlled by a portable device on the neck, into the ear. This device transmits electrical impulses, so the person often experiences a tickling sensation.

An antidote to diseases related to aging?

A study conducted by the University of Leeds and published in the journal Aging revealed that this technique helps protect people from various diseases associated with aging. This is especially true of hypertension and heart disease.

According to Beatrice Bretherton, coordinator of the study, the simulation affects the body’s metabolic balance to perform corrective actions. Fortunately, stimulation of the vagus nerve in the ear does not require the use of medication or other invasive procedures.

You may not be aware of this, but the sympathetic branch of the vagus nerve helps the body prepare to fight or flee. In addition, the parasympathetic branch affects rest and digestion. As people get older, the sympathetic branch will gradually take over.

The technique of stimulating the vagus nerve in the ear is used to reverse this situation. It activates the parasympathetic branch and balances it with the sympathetic branch. There is less stress; which poses a lesser risk of developing certain health conditions under these conditions, such as those we mentioned above.

Stimulation of the vagus nerve for chronic pain

The technique of stimulating the vagus nerve in the ear also has positive effects in the treatment of chronic pain. You must take into account that the vagus nerve begins in the medulla oblongata and innervates the pharynx, esophagus, larynx, trachea, bronchi, heart, stomach, pancreas, liver and some other intestines.

Stimulating the fibers in the vagus nerve reduces pain. However, the biggest challenges doctors face are getting the electrodes in the right place.

Computer models have been able to determine with increasing precision which electrical signals are to be used. Both the intensity and shape of these signals affect the factors.

Additional effects

This type of stimulation has also been effective in eliminating tinnitus. The main feature of this condition is a persistent ringing in the ear that does not come from any external source. It has several causes, ranging from trauma, Ménière’s disease, stress or fatigue due to overtime.

Overall, the revelations about this technique are just the tip of the iceberg. Researchers thought they would find new applications and benefits with this innovative method in the near future.
