Signs Your Vagus Nerve Is Not Functioning Well

low vagal tone symptoms stress fatigue anxiety nervous system

Your vagus nerve plays a vital role in your overall health—so when it’s not working properly, the effects can be widespread.

What Is Low Vagal Tone?

Low vagal tone means your body struggles to activate the “rest and digest” response.

This can leave you stuck in a constant state of stress.

Common Signs of Vagus Nerve Dysfunction

  • Anxiety and chronic stress
  • Poor digestion (bloating, IBS)
  • Fatigue and low energy
  • Rapid heart rate
  • Difficulty recovering from stress
  • Poor sleep

Many of these symptoms—particularly anxiety, poor stress tolerance, and low mood—are closely linked to how well your vagus nerve is functioning.

If you want to understand this connection in more detail and how to improve it, I explain it fully here:

👉 Vagus Nerve Stimulation for Anxiety: How It Works

For endurance athletes, low vagal tone may contribute to slower recovery between training sessions, reduced heart rate variability (HRV) and poorer sleep quality. I explore this in more detail in my article on how Nurosym may support exercise recovery and endurance performance.

A More Targeted Solution

While lifestyle changes are essential, targeted stimulation can accelerate results.

One of the most effective tools available is Nurosym, designed to:

  • Restore nervous system balance

From working with clients as a Nutritional Therapist, I often see these symptoms linked to nervous system dysregulation—and improving vagal tone can play a key role in helping people feel calmer, more energised, and more resilient.

Nurosym for Exercise Recovery: Can Vagus Nerve Stimulation Improve Endurance Performance?

Recovery is often the missing piece of the endurance performance puzzle.

This is where the Nurosym device is generating increasing interest among endurance athletes. By using non-invasive vagus nerve stimulation, Nurosym aims to enhance parasympathetic activity — the body’s “rest and recover” mode — potentially improving heart
