The Vagus Nerve: What It Is & Why You Should Care About It

The Vagus Nerve: What It Is & Why You Should Care About It

January 11, 2021

Running from the brain all the way down through the abdomen, the vagus nerve is the longest and most complex cranial nerve. In fact, because it is so interwoven throughout our bodily systems, we can credit our mind-body connection to this nerve. It ultimately interacts with the parasympathetic (rest & digest) nervous system to control the heart, lungs, and digestive tract. The vagus nerve also plays a big role in the immune system as well as how we experience and recover from stress. All of that being said, it clearly has a big impact on how we feel and function.

So what do we need to watch for regarding the vagus nerve? The wellness of this nerve is described as “tone” and by observing your own vagal tone, you can better know what your body and mind need in any given moment.


Vagal Tone

Weak vagal tone essentially traps a person in the parasympathetic “fight or flight” or dorsal vagal (freeze) response. Ultimately, these responses leave a person feeling unsafe in their own bodies, which is obviously not desirable. Signs of weak vagal tone include, but are not limited to:

  • Anxiety
  • Insomnia
  • Inability to regulate emotions
  • Restlessness
  • Trouble focusing
  • Depression
  • Digestion issues
  • Chronic fatigue
  • Inability to make decisions
  • Numbness in social interactions / relationships (physically and / or emotionally)


Strong vagal tone, on the other hand, keeps a person at ease in their body. It allows a person to feel comfortable even amidst challenges and to feel confident in their own ability to successfully navigate their lives. Obviously, we all prefer to act from this space. Strong vagal tone might look like:

  • Consistent, proper digestion
  • Stable moods
  • Ability to regulate emotions
  • Good sleeping patterns
  • Strong relationships
  • Quick stress recovery
  • Ability to use logic over emotion
  • Ability to make decisions
  • Deeper concentration
  • General sense of peace / wellbeing


Strengthening Vagal Tone

If in reading the above descriptions you classified yourself as having a weak vagal tone, do not distress. There are plenty of practices that can strengthen your vagal tone, and help you thereby feel better in both your mind as well as your body. You might try:

  • Taking cold showers
  • Singing / chanting (especially in sync with others -- resonance / harmony are powerful here)
  • Increasing gut health (eating clean; intermittently fasting; taking probiotic)
  • Doing breathwork
  • Consuming Omega-3 fatty acids
  • Mindfully moving -- note for yourself if you’re needing stimulation or grounding. To stimulate (provoke energy), do backbends (cobra pose, locust, tiger pose, bridge pose, etc). To soothe / ground your energy, do compression poses (child’s pose, forward folds, wind-relieving pose, etc).

The vagus nerve deeply impacts our bodies and minds and therefore deserves our attention. As Francis Bacon famously said, “Knowledge is power.” The more we know and understand the inner workings of ourselves, the more power we have to address issues and create change.

How to Slow Down
How to Slow Down

August 11, 2021

When I was 16 I got my first job. In the application and interview processes, I was coached to say things like “I’m good at multitasking” and “I can work in a fast-paced environment” -- things that would, unbeknownst to my 16 year old self, feed into the western world’s notion of “busy is better.” Years later, I realized that while I don’t enjoy monotony, I definitely don’t work best in a fast-paced environment where I have to multitask. In fact, according to a variety of research out there, most people do better in a slower and more focused environment. Studies have shown that “multitasking increases our brain’s production of cortisol, a hormone that creates stress. Once we’re stressed and mentally fatigued, anxiety builds up. And this leads to stress builds up. It’s a vicious cycle of constant stress and anxiety” (Oshin). But even if we recognize how we might benefit from slowing down -- even if we see the need and have the desire -- how do we actually make it happen?

Building Self-Confidence (in 30 Minutes or Less!)

I’ve never yet met a person who would prefer to feel timid as opposed to confident. In truth, it seems pretty straight forward that we’d all like to feel comfortable in our own skin and while walking through this life. However, it’s not always easy to make that happen. With some targeted work and persistence, we can systematically build our own self-confidence and move through the world with our chins held a bit higher. Check out the ideas below - separated out by timeframes - for some inspiration.

Naps: They're Not Just for Children
Naps: They're Not Just for Children

We know that naps are helpful for children. A bad mood, overt drowsiness, and a need for reset can all be mitigated through the simple grace of some shut eye. But what we don’t often talk about is how many of those same issues are still present in adulthood and can still, indeed, be helped via a nap. As we age, naps can continue to play an important role in our wellness through their myriad benefits.
