Do you want to continually improve your emotional, mental, and physical well-being anytime, anywhere? The external ear is the only place on the body where the vagus nerve sends its only peripheral branch. In fact, the auricular branch of vagus nerve surfaces as the afferent auricular vagus nerve. Afferent means that when we stimulate the periphery (ear, in this case), it signals back to the brain. The ear release can be a simple technique for you to integrate into your life.
