A reset for your nervous system

Sixty seconds.
One hum.
A different nervous system.

HOOM activates your vagus nerve through guided humming — the body's built-in calm switch. No breathwork. No meditation. No 20-minute commitment.

How it works

Three beats.
That's the practice.

Every HOOM session follows the same simple rhythm. No instructions to memorize, no app to fight with — just three counts that quietly rewire your stress response.

01 / Beat one

Inhale

Four counts through the nose. Slow, low, into the belly. The body starts to recognize that nothing is wrong.

Counts 4
02 / Beat two

Hum.

Eight counts of low "mmmmm." The vibration travels down the vagus nerve — the body's calm switch — and the sympathetic spike begins to drop.

Counts 8
03 / Beat three

Reset.

Five cycles. Sixty seconds. You step out into a measurably different nervous system than the one you walked in with.

The problem

Most stress tools
ask for time you
don't have.

i.

20 minutes a day

Meditation expects a window most parents, founders, and anyone with a calendar simply doesn't have.

ii.

Weeks of practice

Breathwork apps promise change — but only after months of compliance you'll likely never sustain.

iii.

Another habit to maintain

Real stress doesn't wait for your routine. It hits in traffic, mid-meeting, at 2 AM with a racing mind.

In those moments

You don't want another practice.
You want relief. Now.

HOOM is not a journey. It's an intervention — a precise, repeatable way to interrupt stress at the level of your nervous system, in less time than it takes to refresh your inbox.

Built on biology

Your body has a calm switch.
It's called the vagus nerve.

It runs from your brainstem, through your throat and chest, down to your gut. When you hum, the vibration travels along it — and your body shifts out of fight-or-flight into rest-and-digest. The science is well-established. HOOM just makes it a daily habit.

  • Humming forces a long, controlled exhale — typically twice as long as the inhale. This shifts the autonomic balance toward the parasympathetic branch within seconds. It's why a sigh feels like relief: the exhale is the relief.
  • The vagus nerve runs alongside the larynx. Vibration from humming mechanically activates it — a direct, drug-free way to send safety signals to the brainstem. Higher vagal tone correlates with better stress recovery, lower resting heart rate, and stronger emotional regulation.
  • Humming raises nasal nitric oxide by roughly 15× over quiet breathing — a finding replicated for over two decades. NO is a vasodilator: it improves oxygen uptake, supports immune function, and gives the practice a measurable physiological signature.
  • The vagus nerve directly slows the heart's pacemaker. Within a few cycles, you'll often see HR drop several beats per minute on a wearable — a reliable, repeatable shift you can verify with your own data.
  • The combined inputs — long exhale, vagal vibration, slowed heart, steady airflow — collectively read as "safe" to the threat-detection circuits in the brainstem. Cortisol drops. The amygdala calms. Clear thinking returns.

The result?
Most people feel the shift in under sixty seconds.

09 · Grounding

Come back to
the body that's here.

4 min · Hum low · for when attention has left the room.

10 · Cravings

instead of acting on it.

3 min · Hum firm · cravings peak in under three minutes.

Calibrated to you

It learns where you resonate.

Every nervous system is different. HOOM's onboarding maps your unique resonance profile — where you feel the hum, how strongly, and how your body responds — then tunes every session to match.

  • Personal HOOM profile Throat, chest, head, or full-body resonance — measured, not guessed.
  • Live group sessions Hum together, daily — synchronized humming with hundreds of other regulators.
  • Haptic + visual sync Phase-cued vibrations and a breathing orb that responds to your real hum.

HOOM is for you if

  • You've tried meditation apps and quietly let the streak break.
  • You need a tool for the moment — traffic, mid-meeting, 2 AM.
  • You want something measurable. HRV, resting heart rate, real change.
  • You're a parent, founder, clinician, or anyone with a noisy nervous system and no time.

It's not for you if

  • You're looking for guided meditation, sleep stories, or soundscapes.
  • You want a magic bullet — HOOM is a tool, not a treatment.
  • You're managing a serious cardiac, respiratory, or psychiatric condition without a clinician in the loop.
  • You believe the only valid practices take 30 minutes.

The research

Not a vibe.
Peer-reviewed.

HOOM didn't invent humming. We just made the practice frictionless. The underlying mechanisms have been studied for decades — here's where to start if you want to read for yourself.

  • i.
    Humming greatly increases nasal nitric oxide

    Weitzberg & Lundberg, American Journal of Respiratory and Critical Care Medicine, 2002. Showed a roughly 15-fold increase in NO during humming vs. quiet breathing — the foundational study.

  • ii.
    The Polyvagal Theory

    Stephen Porges, The Polyvagal Theory (W. W. Norton, 2011). Establishes the vagus nerve's role in social engagement and stress recovery — the framework most clinicians use today.

  • iii.
    Slow-paced breathing & HRV

    Lehrer & Gevirtz, Frontiers in Psychology, 2014. Reviews the evidence that long-exhale breathing patterns measurably increase heart rate variability — a key marker of vagal tone.

  • iv.
    Bhramari (humming) & the autonomic nervous system

    Trivedi et al., International Journal of Yoga, 2023. Recent review of the cardiac and respiratory effects of the traditional humming-bee pranayama practice that HOOM is built on.

HOOM is a wellness tool, not a medical device. It's not a substitute for clinical care. If you're managing a diagnosed condition, please loop in your clinician.

The origin story

HOOM didn't start as an app. It started in a car seat.

My infant son hates the car. Hates it. The only thing — the only thing — that ever calmed him down was when my wife and I started humming to him. Not singing. Not shushing. Humming. Within seconds, his whole body would soften.

"

And here's the thing — babies can't fake regulation.

"

A toddler can pretend. An adult can absolutely pretend. But an infant nervous system either calms down or it doesn't. There's no performance. So when humming worked — every time — I knew something real was happening.

I started reading. Turns out the science was already there, hiding in plain sight: vagus nerve activation, nasal nitric oxide, parasympathetic shift, the lot. Decades of peer-reviewed research, all pointing at this thing my wife and I had stumbled into during rush hour in Chicago traffic.

So I built HOOM. The same tool that calmed my son, designed for the nervous system you walk around with every day.

Common questions

Asked & answered.

Yes. The mechanism is well-documented: prolonged exhalation activates the parasympathetic branch of the vagus nerve, and humming amplifies this by adding vibration to the throat and chest cavities. Humming also boosts nasal nitric oxide by roughly 15× over quiet breathing — a classic finding that's been replicated for over two decades. HOOM doesn't invent the science; it just makes the practice frictionless.
A low hum with closed lips is barely audible to anyone more than a foot away — quieter than typing, much quieter than a yawn. Most people use HOOM in cars, bathrooms, walking between meetings, or right at their desk. The Wind Down practice is built specifically for bed.
Meditation trains attention. Breathwork trains the breath. HOOM is an intervention — designed to shift your physiological state in 60 seconds, then get out of the way. There's no journey, no streak guilt, no spiritual framing. Just a reliable tool you can use 6 times a day or once a week. And you can stack it with anything else you already do.
HOOM has nothing to do with pitch or musicality. The lowest comfortable hum your body produces is the right hum — that's where the chest vibrates most. Onboarding finds your natural resonance in the first 24 seconds.

No. HOOM is a wellness tool, not a treatment. It's not a substitute for medical or mental health care. If you're managing a serious condition — cardiac, respiratory, or psychiatric — please loop in your clinician. Most people use HOOM alongside therapy, exercise, or other practices, not instead of them.
