  • 4 minutes a day. Drug-free. No app needed
Clinician's choice
Dr. James Whitfield Neurologist & Autonomic Specialist
Chronic stress keeps the vagus nerve quiet. When we reactivate it with gentle stimulation, the body remembers how to downshift. Heart rate drops, cortisol drops, and sleep follows naturally.
Dr. Laura Chen Stress Physiology Researcher
Most sleep interventions work on the clock. Melatonin, light therapy, even sleeping pills. But if the problem is a nervous system stuck in overdrive, you need to address the switch itself. The vagus nerve is that switch.
Dr. Sophia Andersen Integrative Medicine Specialist
I used to prescribe sleep aids as a first step. Now I look at the autonomic nervous system first. In many patients, activating the vagus nerve does more for sleep quality than any pill I can write.

Clinical Studies

tVNS and sleep quality. In a double-blind trial with 40 adults with chronic insomnia, sleep quality improved 2.4 times more than placebo over six weeks of daily use. Read the study (Sleep Medicine, 2025)

Cortisol and stress reduction. During a stress test, cortisol stayed at 49.5% of baseline with stimulation vs 106% with placebo. Read the study (Physiology Reports, 2025)

Neck stimulation physiology. In 25 adults, neck tVNS lowered heart rate by 5.7% and increased blood flow by 30.8% after a stress task. Read the study (Neurobiology of Stress, 2020)

Safety. A systematic review of 51 studies with 1,322 participants found tVNS safe and well tolerated. Most common side effect: mild skin tingling.

These studies test the method (transcutaneous vagus nerve stimulation), not this specific device.

How To Use

One evening ritual, four minutes.

  3. Relax. Four minutes. Your heart rate slows, your muscles release, your breathing deepens. That is all it takes.

From people who sleep now

The difference people feel

I was the person who woke up at 2 or 3 AM with my heart racing for no reason. Four months of that and you start dreading bedtime. I use this for 4 minutes before sleep now. First week I noticed I was not waking up at 3 anymore. By week three I was sleeping through.
Sarah M.Age 43 Verified buyer
I carry stress in my neck and shoulders. By the end of the day my jaw is sore from clenching. This was the first thing that actually made my shoulders drop without me trying. I use it after work now, not just at bedtime.
Rachel T.Age 38 Verified buyer
My wife bought this for me because she was tired of me lying there wound up at midnight. I thought it was going to be another thing in the drawer. Three weeks in and I fall asleep before the session ends most nights.
David K.Age 51 Verified buyer
Takes a few days to get used to wearing it. But once I did, the difference was real. I used to need an hour to wind down after work, now 4 minutes with this and I feel like a different person. Giving it 4 stars because the gel runs out faster than I expected.
Jessica L.Age 46 Verified buyer
Honestly skeptical about anything nerve stimulation but the research convinced me to try it. The feeling is strange at first, like a gentle pulse on your neck. By day 5 I was just calmer in the evenings. By week 2 I was out before the timer finished. Worth every dollar.
Mike R.Age 34 Verified buyer
Perimenopause wrecked my sleep and my stress levels. Hot flashes, racing thoughts, wide awake at 4 AM. My doctor said try melatonin. Did nothing. This actually calms my whole body down. I use it twice a day now - after lunch and before bed.
Karen W.Age 49 Verified buyer
Woman lying awake staring at the ceiling
The real problem

Stressed all day. Wired all night.

The stress follows you to bed. Your jaw is clenched, your shoulders are up, your brain is replaying the day on loop. You tried melatonin, breathing exercises, magnesium, the sleep podcast. Nothing works because none of it touches the actual problem.

Your nervous system is stuck in fight-or-flight. Melatonin cannot fix that. It is a clock, not an off-switch. What you need is something that tells your body: stand down.

  • "my body is tired but my brain won't stop"
  • "I carry the stress in my neck and jaw all day"
  • "I wake up at 3 AM with my heart pounding"
  • "too wired to sleep, too stressed to function"

The problem was never your sleep schedule. It is a nervous system that will not let go of the day.

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. When it fires, your body shifts out of fight-or-flight and into rest.

Chronic stress keeps it quiet. Your body forgets how to switch off. The Komfora neckband sends a gentle 4-minute pulse through the skin of your neck, directly to this nerve. No needles, no surgery, no drugs. Just the signal your body stopped sending itself.

Simple diagram: neckband sends pulse to vagus nerve, vagus nerve tells brain to calm down, heart rate and cortisol drop
  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

Why nothing else worked

You were not doing it wrong. You had the wrong tool.

Melatonin tells your body what time it is. That is all it does. If your problem is stress that follows you to bed, a clock does not help. The vagus nerve is the off-switch melatonin never was.

Before you ask

The questions you are actually thinking

Is this not just placebo?

In double-blind trials, people who got real stimulation had measurably lower cortisol and better sleep than people who got the same device with no active pulse. The difference was clear and consistent across multiple studies. We are not asking you to believe - we are asking you to try it for 60 days.

I have tried everything. Why would this be different?

Because most of what you tried works on timing or sedation. Melatonin tells your body what time it is. Sleeping pills knock you out. Neither one touches the nervous system that is keeping you stressed and wired. Vagus nerve stimulation works on that system directly - it tells your brain to shift out of fight-or-flight.

Does it help with stress too, or just sleep?

Both. The vagus nerve controls your entire rest-and-digest response. In clinical trials, cortisol dropped by half during stress. Most people use it before bed, but it works any time you need to come down - after work, before a meeting, during a tough day.

Only 4 minutes? How is that enough?

The electrical pulse activates the vagus nerve directly. It does not need to build up over an hour. In the clinical trials, measurable physiological changes (heart rate, blood flow, cortisol) happened within minutes. Four minutes is enough to shift your nervous system.

Is it safe?

A systematic review of 51 studies with 1,322 people found tVNS safe and well tolerated. The most common side effect is mild skin tingling at the electrode site. Do not use if you have a pacemaker, implanted electronics, heart rhythm disorders, or are pregnant.

Do I need an app?

No. Press the button, adjust the intensity, done. No account, no subscription, no firmware updates.

What does it feel like?

A gentle pulsing on both sides of your neck. Most people describe it as unusual the first time, then barely noticeable after a few sessions. It should never be painful - if it is, turn the intensity down.

How is this different from Pulsetto?

Pulsetto costs $269 for the device, then $139 per year for the app, plus $51 for gel. That is over $460 in year one. Komfora is $149, one time. No app required, no subscription, gel refills are $8. And we have a 60-day money-back guarantee - no restocking fee, no questions.
