Exploring the benefits of vagus nerve stimulation

“Oh, my poor nerves!” cries Mrs Bennet over and over again throughout Jane Austen’s Pride and Prejudice, throwing the whole household into uproar while her resigned husband retreats into his study with a book.

While Mrs Bennet’s dramatic flair provides some of the novel’s best comic relief, her constant agitation reflects something many of us can relate to: a nervous system in overdrive.

Had Mrs Bennet lived in the 21st century, she may have found more relief than just fainting on the nearest chaise lounge. Because now we know that stimulating the vagus nerve can actually help us calm down.

 

What is the vagus nerve?

The vagus nerve takes its name from the Latin term for wandering. And it does, indeed, go on a long wander through your body. Your left and right vagus nerves start in your brain stem, then travel through your neck and into the chest and abdomen, touching key organs including the heart, lungs and digestive tract.

 

Understanding its function

The vagus nerve is part of the parasympathetic nervous system and plays a vital role in regulating many automatic functions that sustain your life, health and wellbeing.

The vagus nerve helps to maintain the balance between stress and relaxation. It influences:

  • Heart rhythm and blood pressure
  • Breathing patterns
  • Digestion and gut function
  • Mucus and saliva production
  • Skin and muscle sensations
  • Taste
  • Mood
  • Urine output.

When functioning optimally, the vagus nerve helps calm the body after stress, regulate emotions, and support healthy organ function.

However, when vagus nerve function is impaired, it can contribute to issues such as anxiety, digestive problems, inflammation, and neurological disorders.

 

Benefits of vagus nerve stimulation

Vagus nerve stimulation (VNS) is a therapy that involves delivering mild electrical impulses to the vagus nerve, either through implanted or non-invasive devices. It has been studied for its potential to regulate brain activity and support recovery

Vagus nerve stimulation for epilepsy

Anti-seizure medications are the preferred therapy for epilepsy but about 30% of on those medications continue to experience seizures. Regular pulses to the brain via the vagus nerve can help stabilise electrical activity and reduce seizure frequency.

A 2025 systematic review and meta-analysis found that 46% of patients with drug-resistant epilepsy experienced a 50% or greater reduction in seizures with vagus nerve stimulation.

Vagus nerve stimulation for stroke recovery

Vagus nerve stimulation paired with physical therapy led to significantly greater improvements in arm function compared to physical therapy alone.

Other potential benefits

How do you stimulate the vagus nerve?

There are several ways to stimulate the vagus nerve, ranging from clinical therapies to self-regulation techniques.

Non-invasive vagus nerve stimulation devices

Non-invasive devices are now available that deliver electrical impulses through the skin, typically at the ear or neck.

Natural ways to stimulate the vagus nerve

There are several ways to stimulate your vagus nerve at home, including:

  • Deep breathing exercises
  • Cold exposure (e.g. splashing cold water on your face)
  • Singing, humming or gargling
  • Yoga and meditation
  • Social connection and laughter.

These activities may help increase vagal tone – the efficiency of your vagus nerve function – helping the body shift from “fight or flight” into a more relaxed, restorative state.

 

How Neurofit Brain Centre supports vagus nerve health

At Neurofit Brain Centre, we use evidence-based therapies that engage the brain and nervous system, including non-invasive techniques that may support vagus nerve stimulation.

Every program at Neurofit is personalised, combining in-clinic brain stimulation and movement therapies with home-based exercises to maximise long-term outcomes.
