Natural Ways to Improve Vagus Nerve Function The vagus nerve, sometimes called the “wandering nerve,” is the longest cranial nerve in the body. It connects the brain to the heart, lungs, and digestive system, making it central to the parasympathetic nervous system. Its function is measured by vagal tone, which reflects how well the body can relax, recover, and maintain balance. High vagal tone is associated with better digestion, lower inflammation, improved heart rate variability, and greater resilience to stress. Fortunately, there are several natural and evidence-based ways to stimulate the vagus nerve and strengthen vagal tone. Deep Breathing and Breathwork One of the simplest and most effective ways to activate the vagus nerve is through slow, diaphragmatic breathing. Extending the exhale activate...
