Vagus Nerve Stimulation (VNS / tVNS)

Grade B — Anxiety and HRV signals are real; longevity endpoint data is preliminary.

The evidence

Transcutaneous vagus nerve stimulation (tVNS) has RCT data for anxiety reduction, HRV improvement, and inflammatory marker decrease. The implantable VNS form is FDA-cleared for treatment-resistant depression and refractory epilepsy; the consumer transcutaneous form is a lower-dose proxy with shorter trial durations.

Our picks

Pulsetto

Pulsetto

Direct neck-clip tVNS device with measured pulse parameters. Stronger published spec transparency than wearable-only competitors.

Apollo Neuro

Apollo Neuro

Wearable mechanoreceptor stimulation (vibration patterns), not direct vagal current. Calming-protocol RCT data, but a different mechanism than true tVNS — included here for category breadth.

Halacha notes

These are discussion points, not pesak. Confirm with your own rav before applying to your practice.

Kosher Evidence Card
Halacha — Shabbat
Activating any electronic stimulator is a melacha. Wearables with pre-set vibration cycles raise grama questions.
Halacha — Yom Tov
Same as Shabbat.
Choleh Status
Anxiety and depression at clinical severity may rise to choleh-relevant; general 'calm-mode' use does not.
Clinic Notes
Home device.
Test Before Use
Confirm no pacemaker / ICD if using direct-current tVNS on the neck. Avoid with active stroke or carotid disease.
Ask Your Rav About
Choleh framing for clinical-anxiety protocols; whether pre-set wearable cycles avoid Shabbat issues.

FAQ

Pulsetto vs. Apollo Neuro — same thing?

No. Pulsetto delivers transcutaneous electric current to the vagus nerve at the neck. Apollo Neuro is a wrist vibration device — separate mechanism and separate RCT base. Both have a place; they are not interchangeable.

Implantable VNS — relevant here?

No. Implantable VNS is a different category, FDA-cleared for specific psychiatric and neurological indications. This page is the consumer non-implantable category.
