The vagal response is a series of unpleasant symptoms that occur when the vagus nerve is stimulated. Often, this response is triggered by certain things like stress, pain, and fear. Symptoms of the vagal response include dizziness, nausea, ringing ears, and sweating.
There are two main causes of vagus nerve dysfunction: previous infection or inflammation and physical or psychological stress.
The vagus nerve stimulates certain muscles in the heart that help to slow heart rate. When it overreacts, it can cause a sudden drop in heart rate and blood pressure, resulting in fainting. This is known as vasovagal syncope.
Chronic stress can worsen symptoms of a dysfunctional vagus nerve. To reduce stress, make lifestyle changes like getting regular exercise, practicing meditation or yoga, and getting enough sleep. You may also want to try relaxation techniques like deep breathing or progressive muscle relaxation.
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.
The Vagus nerve is also important in lowering heart rate and blood pressure. When it becomes overactive it can prevent the heart rate from pumping blood to the brain, which can occur with Vasovagal Syncope. Excess in Vagus activity intermittently can cause loss of consciousness.
Nutrition for the Vagus Nerve
Nutrients that support the vagus nerve include: Choline (to make acetylcholine, our main neurotransmitter) Vitamin B12. Magnesium.
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.
You may have some tingling sensations or slight pain in your neck and temporary hoarseness when the nerve stimulation is on. The stimulator doesn't detect seizure activity or depression symptoms. When it's turned on, the stimulator turns on and off at the intervals selected by your doctor.
In other words, vitamin C increases the ability of the autonomic nervous system, especially the vagus nerve, to respond to pressure variations.
A neurosurgeon will perform VNS, either in a hospital or an outpatient clinic. It is a minimally invasive procedure that can take up to 90 minutes.
In a vagus nerve massage, moderate pressure is applied to the area between the trapezius and sternocleidomastoid muscles in the neck/shoulder area and at the muscles below the base of the skull, with twisting or stroking motions [1].
Given its importance for gut health, vagus nerve sluggishness or damage has been implicated in digestive disorders including dyspepsia, gastroparesis, GERD, ulcerative colitis, anorexia, and bulimia, to name a few [4]. The vagus nerve is important for the rest-and-digest system.
This means the vagus nerve has been associated with mental health conditions, such as anxiety. Low vagal tone is related to poor emotional and attentional regulation, inflammation and depression and can also be used to measure your sensitivity to stress.
The vagus nerve is also noted as being the tenth cranial nerve (designated as CN X). The vagus nerve is actually a set of two nerves, a vagus nerve right side of the neck and a vagus nerve left side of the neck.
An overactive vagus nerve can also result in an abnormally low heart rate, or bradycardia. Individuals with an overactive vagus nerve that results in abnormally low heart rate may also be at risk for first-degree heart block.
In Chinese medicine, different parts of our body correlate with different specific reflexology or pressure points. The vagus nerve point for your hand is right inside of the pinky, for example. This is great because it's so accessible during the course of your day.
“The mammalian vagus nerve regenerates poorly after injury, which can result in loss of speech, difficulty swallowing, abnormal heart rate, and gastroparesis [improper stomach emptying],” the authors explain. In zebrafish, on the other hand, nerve regeneration is generally very successful.
