Zapping or massaging a nerve in the ear might calm your body's stress system

NCT ID NCT07660744

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study explores whether non-invasive vagus nerve stimulation — either with a mild electrical pulse on the ear or through manual massage techniques — can change heart rate variability and ease symptoms like fatigue and poor sleep. Researchers will compare two approaches in healthy adults aged 40 to 70 over 10 days. The goal is to see if these simple techniques can shift the body toward a more relaxed, parasympathetic state.
