Researchers continue to confirm that daily habits of mindset and behavior can create a positive snowball effect through a feedback loop linked to stimulating your vagus nerve. In this entry I will show you 8 habits that stimulate healthy ‘vagal tone’ and allow you to harness the power of your vagus nerve to help you stay calm, cool, and collected in any storm.
Healthy vagal tone is indicated by a slight increase of heart rate when you inhale, and a decrease of heart rate when you exhale. Deep diaphragmatic breathing—with a long, slow exhale—is key to stimulating the vagus nerve and slowing heart rate and blood pressure, especially in times of performance anxiety. A higher vagal tone index is linked to physical and psychological well-being. A low vagal tone index is linked to inflammation, negative moods, loneliness, and heart attacks.
