The polyvagal nervous system is made up of the ventral, dorsal and sympathetic vagal complex.These three branches pass through the same elements that enable us to make sound, including the larynx, lungs and diaphragm.
Polyvagal theory supports the idea that breathwork and talking/singing stimulate this nervous system. More specifically, it stimulates the ventral vagal complex which supports social engagement. Feeling tired, or numb? Within your stress cycle, you're in the phase of freeze and shutdown (dorsal vagal complex). Feeling anxious or angry? That means you’re experiencing fight or flight (sympathetic vagal complex). We all feel that way sometimes, but the key is to be able to cycle through these different responses. Feeling in tune, focused yet calm and energized? That's your ventral nerve complex!
Hanging out with friends, connecting with nature and engaging in creative projects can all stimulate the ventral vagal complex. However, singing is particularly interesting because of its direct interaction with your vocal processes. If you're an actor, singer or public speaker and you feel stuck, nervous or awkward when you talk/sing, it’s probably because you haven’t yet stimulated the ventral vagal nerve!
