What is the Vagus Nerve

The first question really is, what is the Vagus Nerve? The Vagus Nerve has two bunches of sensory nerve cell bodies, these all connect the brainstem to the body to ensure functions are carried out. The nerve allows the brain to monitor and receive information about several different parts of the body and the different functions.

The Vagus Nerve is basically the secondary in command and is responsible for certain sensory activities and motor information for the movement within the body.

The nerve is essentially the most important circuit that links the brain up to the lungs, heart and neck.

The body has multiple nervous system functions provided by the Vagus Nerve, but the functions also contribute to the autonomic nervous system – this consists of parasympathetic and sympathetic parts.

What does the Vagus Nerve Do?

So, what are the key functions that the Vagus Nerve effects?  

  1. Motor: This provides movement for speech, swallowing and the muscles in your neck.
  2. Sensory: Lungs, Heart, Throat, and abdomen.
  3. Special Sensory: This provides the taste sensation behind your tongue.
  4. Parasympathetic: The nerve is also responsible for respiration, heart rate functions and the digestive tract.

Other Vagus Nerve effects also include:

  • Lowering of the heart rate and blood pressure: In some cases, the Vagus Nerve can become overactive and this can lead to the heart being unable to pump enough blood around the body – this can lead to excessive Vagus Nerve activity which could lead to organ damage and loss of consciousness.
  • Decreasing inflammation – The nerve sends an anti-inflammatory response / signal to other parts of the body.
  • Management of Stress, Anxiety and Fear – The Vagus nerve send information from the gut to the brain, which is heavily linked with dealing with anxiety, fear and stress. These signals from the gut help a person deal with or recover from stressful and scary situations.
  • Helps with relaxation and deep breathing – The Vagus Nerve helps with deep breaths to help a person feel more relaxed, this happens by its communication with the diaphragm.

How to stimulate the Vagus Nerve

A question that’s regularly asked – if you wish to stimulate your vagus nerve manually here are a few ways to help you stimulate it:

  1. Humming or singing: Usually when you’re humming or singing, many people see it as a sign of happiness or content, but have you ever felt it sweep away your worries or issues? Well that’s you activating you Vagus Nerve – simply sing or hum to feel a bit better.
  2. The Diving Reflex – To stimulate this approach you will need cold exposure. If you splash cold water in your face, it generates a reflex that slows your heartbeat, reduces anger, relaxes your body and increases blood flow to your brain.
  3. YOGA – A real favourite amongst our customers and others. Yoga is a parasympathetic activation exercise that helps your blood flow, digestion and much more!

Where is the vagus nerve located?

The Vagus Nerve is the longest and most complex of the cranial nerves in the body. The Vagus Nerve runs from the brain through the face, thorax to the abdomen – the nerve contains parasympathetic fibres.
