What is the Vagus Nerve?
Before diving into how to calm the vagus nerve, it’s important to understand its role in the body. The vagus nerve is a central player in the parasympathetic nervous system, which is responsible for calming the body and promoting healing after periods of stress. When the vagus nerve is active, it sends signals to slow down the heart rate, lower blood pressure, and promote digestion and immune response.
A well-functioning vagus nerve is associated with increased resilience to stress, better digestion, lower inflammation, improved mood, and more restful sleep. On the other hand, a sluggish vagus nerve can result in higher levels of stress, poor digestion, and a weakened immune system. Thankfully, there are several ways to stimulate and soothe the vagus nerve, helping to support these vital bodily functions.
1. Deep Breathing Techniques
One of the most effective and accessible ways to calm the vagus nerve is through deep, slow breathing. The act of slowing down the breath and focusing on long exhalations stimulates the parasympathetic nervous system, signaling to your body that it is safe to relax.
How to do it:
Try techniques such as diaphragmatic breathing (also known as abdominal breathing) or box breathing. To practice diaphragmatic breathing, sit or lie down in a comfortable position. Place one hand on your chest and the other on your abdomen. Inhale deeply through your nose for a count of four, allowing your belly to expand as your diaphragm moves down. Then, exhale slowly through your mouth for a count of six. Repeat this for several minutes, focusing on the rise and fall of your abdomen.
Box breathing, a technique often used by athletes and Navy SEALs, involves inhaling for a count of four, holding the breath for four counts, exhaling for four counts, and then holding the exhale for another four counts. This rhythmic breathing helps to activate the vagus nerve and reduce feelings of anxiety or stress.
