Ear stimulation after exercise: the new recovery hack?
NCT ID NCT07371676
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether stimulating a nerve in the ear (vagus nerve) right after running helps the body recover faster. Sixty healthy young adults who don't exercise regularly took part. Researchers measured heart rate and lactic acid levels to see if the stimulation made a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

- What this could lead to
- If it works, this could point toward a simple, drug-free way to speed up recovery after exercise.
- What could go wrong
- This is a small, early-stage study in healthy people only. Results may not apply to athletes or people with health conditions, and the effect may be too small to matter in real life.
