Can a gentle zap to the neck or ear calm body distress?

This study compares two non-invasive devices that stimulate the vagus nerve—one placed on the neck, the other on the ear—to see which better reduces physical discomfort and health-related anxiety in people with somatic symptom disorder. Sixty participants will try both devices in random order, each for two weeks, with a week off in between. The goal is to find a safe, drug-free way to help those who experience troubling physical symptoms and excessive worry about their health.
