First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a mild electrical stimulation on the ear (taVNS) can reduce stress in 60 healthy adults. Participants received either real or fake stimulation before a stressful task. The main goal was to see if it lowered cortisol levels in saliva. Results could help develop a non-drug stress relief method.
