How does the vagus nerve affect anxiety?
The role of the vagus nerve in the parasympathetic nervous system is to slow the sympathetic stress response. Some evidence indicates that chronic VNS reduces anxiety in humans and in rats. If VNS can immediately reduce anxiety, this may, or may not be beneficial for exposure-based therapies.
Why is the vagus nerve called the Wanderer?
Vagus is Latin for wandering, and the vagus nerve fully deserves this name due to its extensive distribution through the body. Inhibition of vagal activity could also be beneficial in some conditions, e.g. reducing activation of vagal respiratory afferents to treat chronic cough.
Does anxiety affect the vagus nerve?
Although this vagal tone is also connected to inflammation, immune system, metabolism and emotional regulation, which is essential to our body. This means the vagus nerve has been associated with mental health conditions, such as anxiety.

How does the vagus nerve affect your breathing?
This neurotransmitter, which is released by the vagus nerve, also allows your lungs to breathe. The vagus nerve affects blood pressure as well. In one recent study, low levels of VNS improved hypertension (high blood pressure) in rats. Elsewhere, researchers have found that similar stimulation could even reduce rates of heart failure ( 10, 11 ).
What are the results of vagus nerve stimulation?
Results. Vagus nerve stimulation may also shorten the recovery time after a seizure. People who’ve had vagus nerve stimulation to treat epilepsy may also experience improvements in mood and quality of life. Research is still mixed on the benefits of implanted vagus nerve stimulation for the treatment of depression.
Can vagus nerve damage cause fainting?
Fainting. One of the more serious vagus nerve symptoms is fainting, which happens when your nerve is overactive and overstimulated. You experience sudden episodes of fainting and collapse. Although fainting on its own is not life threatening, fainting does increase the risk of accidental injuries.
