@Courtney Walsh Did you know? : I read lately that a simple humming stimulates the vagus nerve. « Humming mechanically vibrates the vocal cords and surrounding structures, directly stimulating the vagus nerve. This vibration activates the parasympathetic nervous system (the "rest and digest" mode), instantly shifting the body out of a stressed or anxious state, slowing your heart rate, and increasing heart rate variability (HRV). »
