Can this new gadget reset the nervous system with ultrasound to the vagus nerve? The vagus nerve helps slow your heart rate, deepen breathing, improve digestion, and bring your body back to calm-naturally. ZenBud is designed to support this process, helping you activate your body's natural calming system through non-invasive stimulation. Hosted by Simplecast, an AdsWizz company.
