The vagus nerve is the main pathway of the parasympathetic nervous system — the one that governs recovery, digestion and return to calm. The idea of transcutaneous auricular vagus nerve stimulation (taVNS): apply a gentle, painless current to an area of the ear innervated by a branch of the vagus nerve, to support that 'recovery' side.

The vagus nerve, conductor of recovery

When the vagus nerve is well engaged, the body shifts more easily into parasympathetic mode: heart rate slows, heart-rate variability (HRV) rises, tension eases. Exactly what we seek after stress or effort.

What the research shows

In healthy volunteers, transcutaneous vagus nerve stimulation was associated with a drop in sympathetic nerve activity and a rise in heart-rate variability (Clancy et al., 2014).

Key data

↑ HRV
In healthy subjects
Clancy et al. (2014, Brain Stimulation): taVNS reduces sympathetic activity (microneurography) and increases HRV — markers of better autonomic balance.
Imaging
Optimal auricular sites
Yakunina et al. (2017, Neuromodulation) used functional MRI to identify the ear areas that most effectively activate the central projections of the vagus nerve.
