First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether gentle electrical stimulation on a specific part of the ear could improve the balance between the 'fight-or-flight' and 'rest-and-digest' nervous systems in healthy older adults. Twelve non-smokers aged 65-80 received active or sham stimulation while heart rate variability was measured. The goal was to see if this simple technique could counteract age-related nervous system imbalance.

Active substance

transcutaneous auricular vagus nerve stimulation (tVNS) device

What this could lead to

If it works, this could point toward a simple, non-invasive way to help older adults maintain nervous system balance.

What could go wrong

This is a very small, early study with only 12 healthy participants. Results may not apply to people with health conditions, and the effect may be too small to matter.
