Short answer
The idea of the Schumann resonance rising is the claim that Earth’s roughly 7.83 Hz electromagnetic frequency is climbing toward 30 or 40 Hz. As of 2026, the measurements do not support it. The fundamental Schumann resonance is a natural electromagnetic wave in the cavity between Earth’s surface and the ionosphere, and it has held near 7.8 to 8.0 Hz since the 1960s.1 What people read as a rise is usually amplitude or the chart axis, not the frequency itself.
Key takeaways
- The fundamental is not rising. The fundamental frequency has stayed close to 7.83 Hz across the whole instrumental record, with only a tiny reversible wobble tied to the 11-year solar cycle.
- The “40 Hz” people quote is a chart artifact. Most Schumann spectrograms run from 0 to 40 Hz on the vertical axis, and the higher harmonics sit near 14, 20, 27 and 34 Hz. Seeing energy up there is normal, not a sign the fundamental frequency moved.
- A bright “spike” is amplitude, not frequency. A colourful patch on a live chart means more electromagnetic power (more or closer lightning), not the 7.83 Hz base climbing.
- The myth spreads from misread charts. Screenshots from advocacy sites get reshared as proof of a global “awakening.” The data underneath show a stable resonance.
Is the Schumann resonance rising, at a glance
| Question | Short answer |
|---|---|
| Is the fundamental frequency increasing? | No. It has stayed near 7.8 to 8.0 Hz since the 1960s |
| What about the “rising to 40 Hz” claim? | 40 Hz is the top of the chart’s frequency axis and the range of higher harmonics, not the base tone moving |
| Does a “spike” mean the frequency jumped? | No. A spike is amplitude or power, driven by lightning, not a change in frequency |
| Can it change at all? | Yes, slightly: about 0.1 Hz over a solar cycle, then it returns. No lasting upward trend |
| Where does the myth come from? | Misread spectrograms and framing from advocacy groups, not from geophysics |
Where the “rising Schumann resonance” claim comes from
You have probably seen the posts. A screenshot of a colourful chart, a caption saying the Earth’s frequency has jumped from 7.83 Hz to 30, 40, even 150 Hz, and a conclusion that humanity is “awakening” or that the planet’s vibration is speeding up. It is a genuinely appealing story, and it borrows the credibility of a real physical phenomenon. The Schumann resonance itself is settled science: a set of natural electromagnetic waves in the extremely low frequency (ELF) band that resonate in the cavity, or waveguide, between Earth’s conductive surface and the lower ionosphere, with a fundamental near 7.83 Hz. The German physicist Winfried Otto Schumann predicted it in 1952, and it is driven by global lightning, with roughly 2,000 thunderstorms active at any moment firing about 50 flashes a second that keep the cavity ringing.2
The problem is the leap from that real resonance to a claim about it changing. The “rising frequency” narrative is not something geophysicists report. It comes almost entirely from misreading the live charts, and it has become common enough that Wikipedia keeps a dedicated page cataloguing the conspiracy versions of it.3 The instruments themselves record something much quieter.
What the measurements actually show
The fundamental Schumann frequency has been measured more or less continuously since the definitive spectra of the early 1960s. Across that record it fluctuates inside a narrow band, roughly 7.8 to 8.0 Hz, with predictable daily and seasonal rhythms as the ionosphere shifts between day and night. The single largest long-term modulation is the 11-year solar cycle, which nudges the frequency by only about 0.1 Hz as solar activity waxes and wanes, and then lets it drift back.1
There is no sustained upward secular trend. A dedicated analysis of long-term Schumann records found the fundamental stable over a solar cycle, with the solar-driven wobble as the only meaningful variation, not a climb.1 The number moves a little and comes back, the way a tide rises and falls. It does not march upward year after year.
Why the base tone sits near 7.83 Hz
The frequency is set by geometry, not by mood or events. The lowest mode has a wavelength roughly as long as Earth’s circumference, and dividing the speed of light by that distance lands close to 8 Hz. A cleaner lossless calculation actually predicts about 10.6 Hz; the measured value comes in lower because the real ionosphere is a lossy, imperfect conductor rather than a perfect mirror, and its finite conductivity drags the resonance down. Either way the number is pinned to Earth’s radius and to the gap between the surface of the Earth and the ionosphere. That is why it holds so steady: to move the fundamental mode to 40 Hz you would need to physically shrink the planet or collapse the resonant cavity, not simply change the mood of the people living on it.
The “40 Hz” misunderstanding
Much of the confusion traces to one detail of how the charts are drawn. A standard Schumann spectrogram plots frequency from 0 to about 40 Hz on the vertical axis and time along the horizontal axis, with colour showing power. The reason it reaches 40 Hz is that the resonance is not a single tone. The Schumann resonance frequencies are a family: above the 7.83 Hz fundamental sit a series of higher normal modes, or harmonics, near 14, 20, 27 and 34 Hz.4 Each resonance frequency is approximate, not an exact multiple of the last, and they have all been there since measurements began.
So when someone points at activity near the top of the chart and says the frequency has risen to 40 Hz, they are usually pointing at a harmonic that is a permanent feature of the electromagnetic field, or simply at the ceiling of the axis. The base tone has not moved. The chart just has more than one line on it.
A “spike” is amplitude, not frequency
The second source of the myth is the word “spike.” On a live chart a bright patch of colour looks dramatic, and it is easy to read it as the frequency shooting up. It is not. Colour on these spectrograms encodes amplitude, the strength or power of the signal, not its pitch. A bright region means more electromagnetic energy in the cavity at that moment, which usually means more lightning or closer thunderstorm activity feeding the resonance.2 The Schumann resonance signal on these charts is, at heart, a global lightning meter.
There are other artifacts worth knowing so a chart never fools you again: solid black vertical bars mean the instrument dropped out and the data is simply missing, while sharp bright vertical streaks are local lightning impulses near the sensor. None of these is the 7.83 Hz fundamental changing value. We break this down further in our guide to reading the live Schumann resonance chart and what a spike really means.
Why the myth spreads so easily
Three things line up to keep this story alive. First, the charts are genuinely hard to read without context, and a colourful “spike” is far more shareable than a flat line. Second, the most-reshared charts come from the HeartMath Global Coherence Initiative, an advocacy organisation that promotes a global-consciousness thesis, so its framing already invites a spiritual reading of an instrument readout. Third, the number 7.83 Hz sits right at the low edge of the human EEG alpha band, the range of brain waves, or neural oscillations, that Hans Berger first recorded in the 1920s. That numerical overlap makes the “our brainwaves are syncing with a rising Earth” idea feel plausible, even though the brain waves and the electromagnetic field are separate systems and a coincidence in numbers is not a cause. The planet-wide pulse is sometimes nicknamed Earth’s electromagnetic heartbeat, but that is a metaphor for a steady physical signal, not a statement about human health.
A companion story often rides along with the rising-frequency posts: that NASA fits spacecraft with 7.83 Hz generators because astronauts fall ill without Earth’s frequency. NASA has never documented anything of the kind, and the claim circulates on device-sales pages without a source. The real and much smaller kernel is old circadian research from the 1960s Andechs bunker studies, where a weak roughly 10 Hz field, not 7.83 Hz, slightly nudged the human body clock. That is a finding about sleep timing, not evidence that any of these electromagnetic frequencies are rising or healing anyone.
Independent explainers are blunt about this. The BBC’s Sky at Night notes there is little to no credible evidence that the Schumann resonances affect biological life, and suggests taking the sweeping claims with several shovels of salt.5 None of that is meant unkindly toward people who find the idea moving. It is just that the chart being shared does not show what the caption says it shows.
Does the Schumann resonance ever change, then?
Yes, in small and well-understood ways, and being honest about this matters. The frequency breathes with the ionosphere over a day, shifts a little with the seasons, and wobbles by about 0.1 Hz across the solar cycle as solar activity rises and falls. Amplitude changes far more than frequency does, rising and falling with global lightning activity from hour to hour. And a separate phenomenon, a geomagnetic storm, really can drive measurable changes in the Earth’s magnetic field for a day or two when the Sun sends a burst of charged particles our way.6
That last point is where a lot of “rising” content quietly swaps topics. Geomagnetic storms are a real, measurable, variable thing tracked by the Kp index, and they are a different phenomenon from the steady 7.83 Hz tone. A storm does not push the Schumann fundamental up to 40 Hz. What none of these variations amount to is a one-way climb. Over sixty years of records, the base frequency keeps returning to the same neighbourhood.
It is worth saying what the signal is actually good for, because it is genuinely useful. Geophysicists track global lightning activity through the resonance, and use its subtle shifts as a window into the state of Earth’s atmosphere and the lower ionosphere. That is the real job of the “Schumann chart”: remote sensing of storms and space weather, not a readout of collective mood.
What this means for you
If you came here worried, or hopeful, that a rising Earth frequency is affecting your sleep, mood or body, the calm version is this: the frequency is not rising, so there is nothing there to affect you through that mechanism. The natural Schumann magnetic field is also vanishingly weak, on the order of picotesla, far too faint to be the force that some pages describe. Some readers ask whether a rising resonance is behind ear ringing or tinnitus they have noticed; there is no evidence a picotesla field is audible, and tinnitus has its own well-documented medical causes worth checking with a clinician. For a full, evidence-tiered look at the body claims, separating the real physics from the weak geomagnetic-storm research and the unproven consciousness talk, see our page on Schumann resonance health effects and what the studies really say. As of 2026 the picture is unchanged: a real resonance whose frequency stays put, with no evidence that it is rising.

Frequently asked questions
Is the Schumann resonance actually rising?
No. The fundamental Schumann frequency has stayed near 7.8 to 8.0 Hz since continuous measurements began in the 1960s. It shifts slightly with day and night, the seasons and the 11-year solar cycle, moving about 0.1 Hz before returning. There is no sustained upward trend in the instrumental record.
Why do charts show the Schumann resonance at 30 or 40 Hz?
Because those numbers are the top of the chart’s frequency axis and the range of the higher harmonics. Above the 7.83 Hz fundamental sit resonances near 14, 20, 27 and 34 Hz, which are permanent features. Energy near 40 Hz on a spectrogram is normal, not the base tone climbing.
What does a Schumann resonance “spike” actually mean?
A bright “spike” on a live chart is amplitude, meaning more electromagnetic power in the cavity, usually from more or closer lightning. Colour encodes strength, not frequency. Black vertical bars are missing data and bright vertical streaks are local lightning. None of these means the 7.83 Hz frequency changed.
Could the Schumann resonance rise in the future?
The fundamental is set mainly by the size of Earth and the height of the ionosphere, so a large lasting change would require a major shift in those. Day to day it varies by tiny amounts, and about 0.1 Hz over a solar cycle. Nothing in the data points to a one-way increase.
Who discovered the Schumann resonance and what does ELF mean?
The German physicist Winfried Otto Schumann predicted these waves in 1952, and instruments confirmed them in the early 1960s. ELF stands for extremely low frequency, the band below 3 kHz where the resonance sits. It forms in the Earth-ionosphere waveguide and is driven by global lightning, not by human thought or any spiritual event. That physics is settled, separate from the unproven “rising” claims.
Does a rising Schumann resonance affect human health or consciousness?
Since the frequency is not actually rising, there is no rising signal to act on you. The natural field is also extremely weak, in the picotesla range. Independent reviewers find little credible evidence that the Schumann resonances influence biology, so treat “awakening” claims tied to a rising frequency with real caution.
