Your Nervous System

The vagus nerve serves as the primary conduit for your Parasympathetic Nervous System (PNS), which governs the body’s rest-and-digest functions. It manages heart rate, breathing, and digestion while slowing down organ activity during emergencies to conserve energy.

On the other hand, your Sympathetic Nervous System (SNS) is responsible for the fight-or-flight response. This system gears you up to escape danger or confront threats. Ideally, both systems should work in harmony to maintain balance and health.

Your Vagus Nerve

You possess two vagus nerves, one on each side of your body. They originate from the brainstem and connect to various areas, including the face, neck, chest, heart, diaphragm, and abdomen. The term "vagus" means "wanderer" in Latin, aptly reflecting its extensive network throughout the body.

This mixed nerve has bidirectional communication, with approximately 80% of its fibers sending signals from the body to the brain. The anterior (ventral) portion of the vagus nerve is linked to what researcher Stephen Porges terms the “social engagement system.” It connects vital organs to facial muscles, playing a unique role in mammals. This myelinated section transmits impulses rapidly, affecting facial expressions and influencing feelings of connection, safety, and love.

Imagine how this nerve weaves from your face to your heart, lungs, and stomach. Picture a life devoid of facial expressions—how distressing would that be?

Conversely, the posterior (dorsal) section is unmyelinated and operates at a slower pace. It handles functions like digestion and waste elimination, halting these processes when survival is at stake. This segment is present in all living creatures, from fish to reptiles.

Vagal Tone

A higher vagal tone signifies a quicker recovery from stress. When your vagus nerve operates effectively, your parasympathetic system can do its job. This allows your body to recuperate from stressors and engage with the world instead of remaining in a hypervigilant survival mode.

Increased vagal tone is associated with improved heart rate variability, positive emotions, and better overall health. The vagus nerve monitors your internal and external environments, sending crucial information to your brain. When stress arises, it helps transition from a sympathetic to a parasympathetic state, granting better control over your physiological responses and emotions.

Experiencing constant stress can leave you feeling tense and anxious. Good vagal tone enables your nervous system to function as intended, allowing for emotional fluctuations while helping you manage them more effectively.

Ways to Enhance Your Vagus Nerve

Healing from trauma and managing stress often involves regulating the nervous system, particularly by easing sympathetic overload through the vagus nerve. If you're facing health challenges, improving your body's resilience is possible.

Here are five strategies to enhance your vagus nerve function and promote mental and physical wellness:

1. Practice Deep Breathing: Slowing your breath, especially during exhalation, helps induce relaxation. Engaging your diaphragm stimulates the vagus nerve, counteracting sympathetic dominance. Aim for 6-8 breaths per minute for optimal health.
2. Stay Active: Numerous studies highlight the mental and physical benefits of exercise. Aerobic activities not only manage stress effectively but also improve heart rate variability—a key marker of vagal tone.
3. Cultivate Laughter and Connections: Laughter and social interactions can elevate vagal tone. Despite stress, seek joy and connect with those who uplift you, making it easier to laugh and enjoy life.
4. Engage in Meditation: Research indicates that meditation boosts vagal tone and fosters positive emotions by reducing stress. It encourages slowing down and releasing tension. If you're new to meditation, consider trying popular apps like Calm, Headspace, or Insight Timer.
5. Use Sound: Vocalizing through singing, humming, or repeating mantras can create vibrations that focus the mind. Techniques like “Bee's breath” are effective ways to enhance vagal tone and clear your thoughts.

In conclusion, the vagus nerve is a remarkable component of our bodies, deserving of the attention it receives. By harnessing its potential, you can reset your nervous system and improve overall well-being.
