Whatever might ‘cause’ an emotion – and the roots of the causes of emotion are a source of debate – once it gets going, it isn’t just a thought process. Emotion is meaty and full of pumping hormones and breath pattern alterations and gestures and rushes of fluid. Chemicals get released. Chemicals get washed away. Heart rates speed up and slow down. Our breath rises and falls and its patterns change. Digestion patterns speed up or slow down or get interrupted. What happens in the body affects the body. What happens in the body affects the voice.
