Summary

This trial investigates whether a mild electrical current applied behind the ears—called galvanic vestibular stimulation—can change heart rate variability in healthy adults during their normal workday. Participants receive either real or sham stimulation over four daily sessions while their heart activity is monitored. The study also looks at whether any effects depend on how dizzy people feel during stimulation.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Galvanic Vestibular Stimulation (GVS) using BrainPatch device
What this could lead to: If it works, this could point toward a non-invasive way to improve heart rate regulation and stress resilience in healthy people.
What could go wrong: This is a small, early-stage study in healthy volunteers, so results may not apply to broader populations or have clinical significance.
