Tickling your ear for heart health

A non-invasive method of vagus nerve stimulation through electrical stimulation of the ear is good for the heart, research shows.

Using a standard TENS machine to apply electrical pulses to the tragus, researchers say they are able to reduce the nervous signals that can drive failing hearts too hard.

The effects of transcutaneous vegus nerve stimulation (tVNS) on 48 healthy participants were investigated using heart rate variability and microneurography.
