The vagus nerve is crucial for managing anxiety because it's the main nerve of the parasympathetic nervous system, acting as the "brake" to your "fight-or-flight" stress response, helping you calm down by slowing heart rate and lowering blood pressure; poor vagal tone (dysregulation) can keep you stuck in stress, while stimulating it (through deep breathing, cold exposure, etc.) sends a relaxation signal, improving mood and resilience.

How to try a vagus nerve “reset”: 10 techniques to help ease anxiety
Because the vagus nerve sends information to brain regions important in anxiety regulation (locus coeruleus, orbitofrontal cortex, insula, hippocampus and amygdala), this pathway might be involved in perceiving or manifesting various somatic and cognitive symptoms that characterize anxiety disorders.
The vagal response is a series of symptoms that occur when the vagus nerve is stimulated. This response can be triggered by things like stress, pain, and fear. Symptoms of the vagal response include dizziness, nausea, tunnel vision, and sometimes fainting (vasovagal syncope).
When the vagus nerve is functioning effectively, it helps promote emotional balance. When impaired or disrupted, it can be difficult to calm down after experiencing a stressor. Increased heart rate, elevated blood pressure, rapid breathing, and other anxiety symptoms may persist long after the stressor is gone.
While no specific vitamin can “cure” the vagus nerve, maintaining adequate levels of vitamins B12 and D is essential for full vagus nerve activity and health. These vitamins support the nervous system and overall well-being.
The parasympathetic response is regulated largely by the vagus nerve. It contributes to digestion and immune response. Therefore, chronic stress and trauma can negatively impact this nerve leading to issues with your internal processes.
At UCSF Health, our neurologists and neurosurgeons have expertise in implanting vagal nerve stimulators to treat seizures caused by diseases such as epilepsy.
A diet that supports the microbiome's production of butyrate, a short chain fatty acid, directly activates the vagus nerve. The microbiome uses foods like oatmeal, brown rice, potatoes, beans, lentils, chickpeas, fruits, veggies, nuts, and seeds to make butyrate. Butyrate also naturally occurs in butter.
Vagus Nerve Reset is a science-backed, four-week program designed to help you restore emotional health, relieve chronic stress, and rewire your nervous system using natural and effective techniques. When your vagus nerve is underactive, your body remains in survival mode.
After consumption of the caffeine-containing beverage, a transient and significant increase (P < 0.001) in spectral integrated values (areas under the curve) of high frequency power (high component, HC) was observed, and at 30 min the value was significantly greater than in controls (P < 0.02), suggesting an increase ...
Auricular points – The ear has a number of points that can stimulate the vagus nerve, including the cymba conchae, the tragus, and the cavum conchae.
Conclusions: Right lateral decubitus position leads to the highest vagal modulation in the controls, whereas the supine position leads to the lowest vagal modulation in the CAD patients.
When overstimulated, it can cause symptoms such as vomiting, dizziness and abdomen pain. However, it is possible to soothe and relax the vagus nerve by utilising breathing exercises that slow the heart rate and relax the body.
Physical pain caused by pinched nerves can influence mental and emotional health. Studies have shown that people with neck pain tend to have depression and anxiety, and this can lead to other comorbidities (1).
Signs of Vagus Nerve Dysfunction
Common symptoms include chronic neck and shoulder pain, unexplained dizziness, digestive problems, anxiety, difficulty swallowing, voice changes, and persistent fatigue. Many people also experience heart palpitations, blood pressure fluctuations, and heightened sensitivity to stress.
Six reasons you should see a neurologist
Distal vagal lesions occur as an isolated paralysis of the vagus nerve with no symptoms or signs referable to the oropharynx. Either computed tomography (CT) or magnetic resonance imaging can be used to diagnose proximal or distal lesions.
Physical activity can positively affect your mood and reduce stress. Walking is a great way to start, but if you want something more invigorating, try a heart-pumping aerobic activity like jogging, dance, or swimming. Just make sure you check with your doctor first. Try tai-chi or other relaxation exercises.
The nerve branches out to multiple organs, including your heart, lungs, liver, spleen, stomach, intestines, and kidneys. It is a critical component of your autonomic nervous system (ANS) which regulates involuntary physiologic processes like heart rate, blood pressure, and respiration.
Vitamin D deficiency is linked to depression, anxiety, and cognitive decline. Vitamin D enhances serotonin synthesis, has anti-inflammatory and neuroprotective effects, and regulates the hypothalamic-pituitary-adrenal axis and circadian rhythms.
In GUTS, PNS is the key system controlling the stress response (particularly the vagus nerve and the prefrontal cortex activity) [113]. Of note, preclinical data suggest that magnesium may be important for the functionality of these central systems.
Seven vitamins known to support nerve repair are B1 (thiamine), B2 (riboflavin), B6 (pyridoxine), B12 (cobalamin), Vitamin D, Vitamin E, and Vitamin C. These vitamins promote nerve regeneration, reduce inflammation, and provide antioxidant protection to support overall nerve health.
