I have been teaching about the vagus nerve for years, sharing this post and the post I wrote on how I discovered this vagus nerve healing fun, before vagus nerve - yoga science research was becoming more mainstream.

Recently, I learned some interesting information in regards to the vagus nerve and western medicine. Someone I love had a spell that medical people refer to as a vagal response. Have you ever heard the term "vagaled out."
When the spell was first happening, I checked for the obvious
-stroke check first and when I was clear that was not the issue... I quickly checked heart rate and heart beat strength. Heart rate was way down & thready feeling, person feels like they are going to faint, and loss of color in the face. So I knew we were most likely dealing with a vagus response.
