Vagal tone refers to the activity of the vagus nerve, which controls your involuntary "rest-and-digest" functions like heart rate, digestion, and immune responses. High vagal tone indicates a well-regulated nervous system that easily manages stress; low vagal tone leaves your body stuck in a chronically activated "fight-or-flight" mode. [1234]
The Vagal Tone Spectrum
  • High Vagal Tone: Associated with a lower resting heart rate, stable blood pressure, and higher heart rate variability (HRV). Your body can easily recover from stress and return to equilibrium.
  • Low Vagal Tone: Associated with stress sensitivity, anxiety, digestive issues (like IBS or acid reflux), and chronic inflammation. [1234]
How It’s Measured
Vagal tone cannot be measured directly, but it is typically assessed indirectly via Heart Rate Variability (HRV). A high HRV indicates strong vagal tone, meaning your heart rate fluctuates healthily in response to your breathing and environment. [1234]
How to Improve Vagal Tone
You can actively stimulate your vagus nerve to enhance your vagal tone and shift your body out of stress mode: [12]
  • Deep, slow breathing: Practicing diaphragmatic breathing (e.g., box breathing or 4-7-8 breathing) signals safety to your nervous system.
  • Cold exposure: Splashing freezing water on your face or taking a cold plunge.
  • Vocal stimulation: Because the vagus nerve passes through the throat, humming, singing, or gargling water vigorously can stimulate it.
  • Mind-body practices: Activities like yoga, meditation, and acupuncture. [12345]
