Ear zaps and deep breaths: a new way to supercharge your workout?
NCT ID NCT06796101
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at whether stimulating a nerve in the ear (vagus nerve) or doing controlled breathing exercises can improve physical performance and affect the nervous system. 64 healthy, moderately active men took part. The goal was to see how these two approaches compare and how they work, not to treat any illness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- auricular vagus nerve stimulation device and controlled breathing exercises
- What this could lead to
- If it works, this could point toward simple, non-drug ways to boost physical performance and manage stress in healthy people.
- What could go wrong
- This is a small, early-stage study in healthy men only, so results may not apply to others. It is designed to gather knowledge, not to treat any disease.
