But what does calming your nervous system really mean? Many people would describe it as slowing the heart rate, deepening the breath, and relaxing different muscles—but what actually connects these sensations to the brain? Well, allow us to introduce you to the vagus nerve, the part of the body that seems to explain how our minds control our bodies, how our bodies influence our minds and might give us the tools we need to calm them both. If you haven’t heard of the vagus nerve, you’re not alone. And it might be because, although scientists know it has many functions, they aren’t sure exactly how this nerve actually works. What we do know is that it’s a major regulator of the peripheral nervous system, which is also known as the “rest and digest” response because of its ability to slow our pulse and lower our blood pressure. The vagus nerve is also a central player in the gut-brain axis, which has become a pretty big deal in the wellness world. So what does the vagus nerve mean for mental health? Low vagal tone is associated3 with poor emotional and attentional regulation, inflammation, depression, and is even used as a measurement for a person’s sensitivity to stress. Meanwhile, a healthy vagal tone is associated with the opposite: positive emotions and psychological balance. Some studies have even shown that increasing vagal tone could be helpful in treating addiction and certain cravings. Knowing this, it might be time—in honor of Mental Health Month—for all of us to study up on this very important part of the body. Looking for more anti-anxiety tips?
