5 Easy Ways to Activate the Vagus Nerve and Reduce Anxiety

In this episode of the Be Well by Kelly podcast, host Kelly LeVeque sits down with Dr. Nicole Cain—naturopathic doctor, trauma-informed clinician, and author of Panic Proof—to talk about one of the most underrated tools for calming anxiety: the vagus nerve. Often referred to as the body’s “calm switch,” the vagus nerve connects your brain to your body and plays a vital role in emotional regulation, digestion, heart rate, and stress recovery. Dr. Cain explains how activating this nerve can dramatically reduce anxiety, regulate the nervous system, and help both adults and kids feel more grounded and resilient, without medication.

What Is the Vagus Nerve?

The vagus nerve (from the Latin word for “wandering”) is the longest cranial nerve in the body, stretching from the brainstem down through the neck, chest, and gut. It’s the main component of the parasympathetic nervous system, responsible for the “rest and digest” response that balances out the body’s stress reactions.

Key roles of the vagus nerve:

Regulates heart rate and breathing
Sends calming signals from the gut to the brain
Helps the body recover after stress
Supports digestion, immune function, and emotional regulation

Why the Vagus Nerve Matters for Anxiety

When the vagus nerve is activated and “toned,” it helps calm the nervous system and counteract anxiety responses. But when it’s underactive—often due to chronic stress, trauma, gut inflammation, or hormone imbalance—it can leave you feeling stuck in fight-or-flight mode.

Signs of poor vagal tone:

Feeling anxious or on edge most of the time
Shallow breathing or heart palpitations
Trouble sleeping or digesting food
Emotional dysregulation or frequent meltdowns (in kids and adults)

“Stimulating the vagus nerve is one of the most effective natural tools we have to calm anxiety—no prescription required.” – Dr. Nicole Cain

5 Simple Ways to Activate the Vagus Nerve

You don’t need fancy equipment or hours of meditation. The vagus nerve responds best to consistent, gentle input. Here are simple strategies you can try at home:

1. Deep, Slow Breathing

Try breathing in for 4 seconds, out for 8.
Exhaling longer than you inhale triggers a vagal response that signals safety to the brain.

2. Cold Exposure

Sip cold water, splash your face, or apply a cold pack to your neck or chest.
Even 30 seconds can signal the vagus nerve to reset and regulate.

3. Humming, Singing, or Gargling

The vagus nerve runs through your vocal cords. Sound vibrations stimulate it naturally.
Make it fun with kids—hum songs in the car or gargle during toothbrushing time.

4. Left Nostril Breathing

In yoga, this is used to activate the parasympathetic system.
Try breathing only through your left nostril for 1–2 minutes to calm down quickly.

5. Eye Movement & Peripheral Vision (The Salience Hack)

Look left, then right, then far out to the horizon.
This cues the nervous system that you’re not in immediate danger—a technique often used in trauma recovery.

The Vagus Nerve, Kids, and Emotional Regulation

Children often express anxiety somatically—tummy aches, crying, or fidgeting—because they don’t yet have the language to explain their feelings. Helping them activate their vagus nerve gives them a felt sense of safety, even if they don’t know the science.

Try this with your child:

Cuddle up with them and take slow breaths together.
Rub their back or sing gently.
Give them something cold to drink or chew.
Play “freeze dance” to shift between energy and calm.

Tying It Back to the 4-Step Anxiety Ritual

Dr. Nicole Cain’s 4-step ritual for healing anxiety begins with getting into the body, and the vagus nerve is the quickest way to do just that. Every grounding technique she recommends (breathwork, cold water, eye movement, etc.) works in part by activating this nerve. Think of vagus nerve stimulation as your fast-pass to calm.

One Small Moment at a Time

You don’t have to live in a state of chronic stress. And neither do your kids. By understanding and supporting the vagus nerve, you’re not just calming anxiety—you’re rewiring your family’s response to stress, one small moment at a time. In a world that’s constantly overstimulating our nervous systems, the vagus nerve is your built-in “off switch.” Learn to use it well, and you’ll help yourself—and your children—feel more grounded, present, and truly safe.
