Yoga and the Vagus Nerve: How Breathwork Shapes Our Stress Response By Yogylavkush | International Yoga Day 2025 – Yoga for One Earth, One Health

Modern life constantly triggers our stress response—the “fight or flight” mode governed by the sympathetic nervous system. But hidden within our bodies lies a powerful ally for calm: the vagus nerve. It’s the body’s secret pathway to peace, and yogic breathwork offers the keys to activate it.

What Is the Vagus Nerve?

The vagus nerve is the longest cranial nerve in the body. It connects the brain to major organs such as the heart, lungs, and gut, playing a critical role in the parasympathetic nervous system, which governs rest, digestion, and recovery.

Breath as a Remote Control for the Nervous System

Scientific studies, including those published in Frontiers in Human Neuroscience, show that slow, deep, diaphragmatic breathing stimulates vagal tone—an indicator of how well the vagus nerve is functioning. Higher vagal tone is linked to:

  • Reduced heart rate and blood pressure

  • Lower cortisol (stress hormone) levels

  • Improved digestion and gut health

  • Enhanced emotional regulation and mental clarity

This is where Pranayama steps in.

Pranayama: The Yogic Science Behind It

Techniques like Nadi Shodhana (alternate nostril breathing), Bhramari (humming bee breath), and Ujjayi (victorious breath) are not just ancient rituals—they are scientifically validated interventions that modulate the autonomic nervous system.

A 2013 study in the Journal of Clinical Psychology observed that daily practice of alternate nostril breathing for just 10 minutes significantly improved heart rate variability (a marker of vagal health) and reduced symptoms of anxiety in participants.

Your Practice, Your Peace

By mindfully engaging the breath through yogic techniques, we learn to tap into the body’s self-healing mechanisms. This isn’t about escaping the world—it’s about responding to it with resilience, clarity, and grace.

> “Yoga is the journey of the self, through the self, to the self.” – Bhagavad Gita

On this International Yoga Day, let’s celebrate the profound science within the sacred. With every conscious breath, we invite healing—not just for ourselves, but for our shared Earth.

How to keep the respiratory system healthy through Pranayama (Breathing)

Breathing is an essential process that ensures the exchange of oxygen and carbon dioxide in our body. It involves the respiratory system, which consists of the lungs, air passages, and muscles that aid in breathing. The respiratory system allows us to inhale air into our lungs, where oxygen from the air diffuses into the bloodstream and is transported to the body's cells. At the same time, carbon dioxide produced by the body's cells is transported to the lungs and expelled from the body through exhalation. In this article, we will discuss the process of breathing in detail, as well as the different factors that affect the respiratory system. Anatomy of the Respiratory System The respiratory system comprises various organs and structures that are responsible for the process of breathing. These include: 1. Nose: The nose is the primary organ of the respiratory system that functions as an air filter. As we inhale air, it passes through the nostrils and is filtered by tiny hairs ca...

The Breath-Earth Connection: Carbon, Oxygen & Our Interdependence !!

The Breath-Earth Connection: Carbon, Oxygen & Our Interdependence By Yogylavkush | International Yoga Day 2025 – Yoga for One Earth, One Health Every breath we take is a dialogue with the Earth. Inhale: oxygen produced by trees, algae, and plants. Exhale: carbon dioxide, returned to fuel photosynthesis. This breath-exchange is not simply biology—it is interdependence, encoded in our very existence. Through the lens of yoga, it becomes even more profound. Breath as a Bridge Between Body and Biosphere In yogic philosophy, Prana is the vital life force carried by breath. In science, it's the dynamic equilibrium of gases exchanged between humans and Earth. Both perspectives point to one truth: breath connects self to planet . The carbon-oxygen cycle —one of nature’s most intricate symphonies—keeps ecosystems alive. Trees act as planetary lungs, absorbing our exhaled carbon and releasing oxygen in return. On land, rainforests play a key role. In oceans, phytoplankton —tiny pl...
