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.

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.
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 full daily-use range, 0.01 to 999.99 Hz. Set 7.83 Hz at night for grounding. Move to the higher daily frequencies after meals or during peak work hours when the stomach starts bracing. The same field, in three different states.
The widest range available: 0.01 to 9,999.99 Hz with 0.01 Hz precision. Five preset buttons let you store your night frequency, your workday frequency, and your wind-down. The full spectrum, one tap away from each other.
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.
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.
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.
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.
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.
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.
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.

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.
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.
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."

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.
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.
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.
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.

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.
