    The Gut That Won't Settle. Until It Recognizes the Signal It Was Built For.

    The Schumann brings Earth's 7.83 Hz resonance back into the rooms where you eat, work, and live. The same field your gut-brain axis evolved inside, scientifically associated with vagal tone, parasympathetic activation, and the calmer baseline digestion was built to work from. The 30-night promise: feel the field, or every dollar back.

    • What users report: a gut that settles within the first week. Less of the pre-meeting knot, less of the 4pm bloat. A morning that doesn't start with the stomach already braced for something.
    • Built in Slovenia. FCC certified. The team behind 10,000+ customer devices already in the world.
    • 30 nights to feel the field, or every dollar back. No restocking fees. No questions. Keep the experiment risk-free.

    Not a Treatment. An Environment.

    Three Devices. Three Depths. One Field That Quiets the System.

    For the gut that has been bracing for years. The mechanism is the same across all three: a real, measurable electromagnetic field at Earth's 7.83 Hz resonance, scientifically associated with vagal tone and the parasympathetic state digestion was built inside. What changes between the rungs is how much of the spectrum you want in your hands.

    Why V1 for gut

    One fixed frequency: 7.83 Hz, Earth's resonance. The same field the vagus nerve and the enteric nervous system evolved inside. Place it where you sleep, leave it running, and let the field do the slow work of bringing the room back to rest and digest.

    The Pattern, Quietly

    Another lunch you couldn't actually digest. Another batch of supplements that almost worked. Another stomach that wouldn't settle on a schedule anyone could explain.

    You've been doing this for years. The field your gut-brain axis evolved inside has been missing every one of them. The next 30 nights are the cheapest experiment you can run on the pattern. Don't feel the field, every dollar comes back.

    • Otto Schumann found it in 1952. Your gut-brain axis has known it a lot longer than that.

      The Earth produces a measurable electromagnetic resonance at 7.83 Hz, generated by lightning activity between the planet's surface and the ionosphere. Every nervous system on Earth, human or otherwise, evolved inside it. The vagus nerve, the enteric nervous system, the second brain in your gut: all of it tuned to a signal that has been present for as long as life has been here. Indoor walls block it. The Schumann brings it back into the room.

    • This is a real electromagnetic field. Not an app. Not an audio loop.

      The Schumann uses a Mobius coil to emit an actual measurable field in the space around the device. No headphones. No sound. No app to remember to open. Silent. Continuous. Working in the background of the room you're already in, while your body does what bodies have always done: read the field and regulate accordingly.

    • Why the signal reaches the gut at all: the vagus nerve.

      The vagus nerve runs from the base of the brain down through every major organ in the digestive tract. It is the longest cranial nerve in the body and the central wire connecting brain to gut. When the autonomic nervous system shifts into parasympathetic mode, also called rest and digest, the vagus carries the signal that lets digestion actually happen. A peer-reviewed study by Ghaly & Teplitz reported a 47% reduction in cortisol, the hormone that holds the system in sympathetic dominance, among adults exposed to an Earth-resonance-grounded environment. The Schumann does not stimulate the vagus nerve directly. It restores the environmental field the vagus was built to operate inside.

    • Same field NASA puts in spacecraft.

      NASA installs Schumann generators in spacecraft so astronauts don't lose their internal orientation in orbit, where Earth's field can no longer reach them. The same principle applies indoors. Walls aren't orbit, but they block the same field. The fix is the same: bring it back.

    • What users report, in their own words.

      A gut that settles within the first week. Less of the pre-meeting knot. Less of the 4pm bloat. Mornings that don't start with the stomach already braced for something. The body finds the field first. The mind catches up later. Designed to support the rest, focus, and calm modern indoor life has slowly stripped away.

    • Three rungs, because one size does not fit one nervous system.

      V1 is the simplest doorway: one fixed frequency, on for weeks at a time. V2 Pro opens the daily-use range, 0.01 to 999.99 Hz, so you can choose what the room is tuned to depending on the hour. V3 Max extends to 9,999.99 Hz, the full spectrum, with five preset buttons for the protocols you keep returning to. Same field. Different relationships with it.

    • Ships in 2 to 5 days. Free to the US, Canada, and Australia.

      Same-day fulfillment from our US warehouse on weekdays. 12-month warranty included on every device. Tracking from the moment your device leaves our facility.

    • Place it. Plug it in. Forget about it.

      The device sits flat on a surface within the room you want grounded. For gut, the bedroom is the most common spot: the field works while you sleep, which is when your parasympathetic system does most of its work. Some users put a second device on a kitchen or dining surface for around meals. Coverage scales by model: up to 190 sq ft for V1, up to 250 sq ft for V2 Pro and V3 Max.

    • Frequency selection on V2 Pro and V3 Max is up to you.

      V1 is locked at 7.83 Hz: nothing to choose. V2 Pro lets you adjust across the daily range and switch between sine and square waveforms. V3 Max adds five preset buttons so your night frequency, your workday frequency, and your wind-down frequency are one tap apart. For gut, the most common starting point is 7.83 Hz overnight, with adjustments during the day for those who want to experiment.

    • Try it for 30 nights. If the field doesn't reach you, every dollar back.

      30 nights is the window. If you don't feel a change in your sleep, your nervous system baseline, or the stomach that has been bracing for years, write us one email and we refund every dollar. You keep the device for the inconvenience.

    "What we hear most from people coming to The Schumann for gut issues: the stomach doesn't stop bracing on a schedule. It just stops being the first thing they think about at lunch. That's the field doing its work. Quietly. In the background. Where the bracing used to live."

    From the People Who Stopped Waiting for the Gut to Settle on Its Own.

    Brandon W. · Australia Verified buyer
    "Sensitive system, finally settling."

    If you're someone who feels everything in your body before your head catches up, you need this. The stomach knot I'd had for years started easing in the first two weeks. I sleep deeper. My partner is dreaming again. Best way I can describe it: like propping up a plant with a stake so the wind stops moving it. Quiet, steady, hard to unsee once you feel it.

    Caroline H. · United States Verified buyer
    "Two months in, everything quieted."

    I've been using the V2 Pro for about two months and my sleep, my gut, and my general peace of mind have all improved considerably. I'm not having those after-lunch crashes where my stomach feels like a brick anymore. Customer service has been wonderful too. I had a few questions early on and they answered every one. So happy with my purchase.

    Mia R. · United States Verified buyer
    "I noticed I'd stopped reaching for the antacids."

    Not in any dramatic way. Just one day I realized the bottle had been on the counter untouched for a week. I get a stomach knot before any big work thing, always have, and that hasn't gone away completely. But the in-between time is so much quieter than it used to be. I run mine at night and during the workday. I have no idea what the mechanism actually is. Something shifted.

    Laurel K. · United States Verified buyer
    "The 4pm bloat is just not there most days now."

    I'm 41. For the last six or seven years I've had a stomach that swelled up by every afternoon. Doctors said it was stress-related, which I knew, but knowing didn't help. I got the V1 mostly for sleep and didn't connect it to my gut for a couple weeks. Then I realized I wasn't changing into stretch pants at 5pm anymore. Both of those things are true and I didn't make either of them happen on purpose.

    Questions That Come Up.

    Is this the same device sold on the regular product pages?
    Yes. The V1 Classic, V2 Pro, and V3 Max here are the same devices on our standard product pages, with the same 12-month warranty and 30-night promise. This page is built specifically for people who've come to us looking for support with digestion or related nervous system patterns, so we're showing all three rungs side by side rather than one at a time.
    How is this different from things I've already tried for digestion?
    Most things you've tried target the symptom or the food. The Schumann doesn't do either. It restores a baseline environmental condition: the 7.83 Hz field your gut-brain axis evolved inside, which indoor life has been blocking for decades. It isn't a treatment, it's an environment. What users report is that with the field back in the room, the patterns the nervous system was managing shift on their own. That's the experiment the 30-night promise is built for.
    When will I feel a difference?
    Some people feel the field within the first hour. Others notice changes in their sleep and digestion after the first week. A smaller group describes the change as so gradual they only see it looking back. The most consistent reports come at the two-to-four week mark, which is why the 30-night promise exists: long enough for your nervous system to register the field, short enough that you're not locked into something that isn't working.
    Is it safe around children, pets, and the elderly?
    Yes. The Schumann emits a very low-intensity, non-ionizing electromagnetic field at intensities far below anything associated with harm. There's no sound, no heat, no vibration. Many customers tell us their pets naturally gravitate toward the device. If anyone in the household has a pacemaker or other implanted medical device, check with their physician first, the same way you would with any electronic device.
    What if I have a pacemaker or other implanted medical device?
    Please consult your doctor before using The Schumann. Our devices produce a low-intensity electromagnetic field, and while it's well below intensities known to cause issues, anyone with an implanted medical device should clear it with their physician first. The same precaution applies to most consumer electronics.
    What if I refund my order?
    Write us one email within 30 nights of receiving your device and we refund every dollar. No restocking fees on the device itself. Original and return shipping costs are the customer's responsibility per our standard return policy. We respond to refund requests within 5 business days.
    Can this be a gift?
    Yes. A lot of our customers buy The Schumann for parents, partners, and friends who've been quietly carrying chronic gut issues or sleep issues for years. We can ship gift orders with no invoice in the package. Email us after checkout if you'd like a gift note included.
    When does it ship?
    Same-day fulfillment on orders placed before 2 PM local warehouse time on weekdays. Delivery is 2 to 5 days for the US, Canada, and Australia. Tracking is sent the moment your device leaves the facility.

    Stop Waiting for the Gut to Settle on Its Own.

    The pattern isn't on a timer. Modern indoor life has been quietly subtracting the field your gut-brain axis was built for, decade after decade, room after room. 30 nights with it back in the space you sleep in is the experiment that costs you nothing if it doesn't work. Three devices. Three depths of access. One field that quiets the system.
