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:
