Your body has a built-in off-switch

The vagus nerve. It runs from your neck to your brain.

Every mammal has one. It is the nerve that tells your heart to slow, your muscles to unclench, your cortisol to drop. Chronic stress keeps it quiet. The Komfora neckband sends a gentle 4-minute pulse through the skin of your neck, directly to this nerve.

  1. 01

    It activates your vagus nerve

    A gentle electrical pulse travels through the skin of your neck to the vagus nerve underneath. The same nerve your body uses to slow your heart, release your muscles, and drop your cortisol.

  2. 02

    Your nervous system shifts

    The vagus nerve tells your brain to stand down. Stress hormones drop. Your breathing deepens. Your body moves from fight-or-flight into the state it needs to rest and recover.

Transcutaneous vagus nerve stimulation (tVNS) is a non-invasive method studied in over 50 clinical trials with more than 1,300 participants.

Measured, not felt

The research behind vagus nerve stimulation

Not testimonials. Not a founder's hunch. Peer-reviewed, sham-controlled clinical trials on sleep and stress.

Cortisol cut in half

During a stress test, cortisol stayed at 49.5% of baseline with stimulation vs 106% with placebo
