Earth's Vanishingly Small Frequency 00:14:18
The Schumann resonance is the name given to some certain low frequencies in a narrow band of the Earth's atmosphere that resonates the energy output of lightning striking constantly all around the world.
It's a neat little tidbit of geophysics, but that's not good enough for the spiritualist crowd who regard it as some sort of Mother Earth frequency that can provide all kinds of healing powers and energies.

Facts and Fiction of the Schumann Resonances.
It's increasingly hard to find a webpage dedicated to the sales of alternative medicine products or new age spirituality that does not cite the Schumann resonances as proof that some product or service is rooted in science.
This mysterious number of 7.83 comes up again and again in sales pitches as a sort of miracle frequency that can bring you health and wellness.
Today we're going to see what the Schumann resonances actually are, how they formed and what they do, and see if we can determine whether they are in fact related to human health.
In a nutshell, the Schumann resonances are the name given to the resonant frequency of the Earth's atmosphere between the surface and the densest part of the ionosphere.
They're named for the German physicist Winfried Otto Schumann, who worked briefly in the United States after World War II and predicted that the Earth's atmosphere would resonate certain electromagnetic frequencies.
The closed space inside a bottle has a resonant frequency which becomes audible when you blow across it.
This particular bottle has a resonant frequency of about 196 Hertz.
That's the speed at which the waves bounce back and forth between the sides of the bottle at the speed of sound propagating via the air molecules.
Electromagnetic radiation is similar except the waves travel at the speed of light, propagating via electrons in the atmosphere.
The speed of light is a lot faster than the speed of sound, but the electromagnetic waves have a lot further to go between the ground and the ionosphere than do the sound waves between the sides of the bottle.
This atmospheric electromagnetic resonant frequency is 7.83 Hz, which is near the bottom of the ELF frequency range, or extremely low frequency.
The atmosphere has its own radio equivalent of someone blowing across the top of the bottle.
Lightning.
Lightning is constantly flashing all around the world, many times per second, and each bolt is a radio source.
This means our atmosphere is continuously resonating with a radio frequency of 7.83 Hz, along with progressively weaker harmonics at 14.3, 20.8, 27.3, and 33.8 Hz.
These are the Schumann resonances.
It's nothing to do with the Earth itself, or with life, or with any spiritual phenomenon.
It's merely an artifact of the physical dimensions of the space between the surface of the Earth and the ionosphere.
Every planet and moon that has an ionosphere has its own set of Schumann resonances defined by the planet's size.
The amount of resonance fluctuates as the ionosphere becomes more or less dense, which depends largely on the amount of solar radiation striking it.
At night, that part of the ionosphere that's in the Earth's shadow thins out.
Another influence is that the world's three lightning hotspots, Asia, Africa, and South America, also follow a day and night cycle and are seasonal as well.
Thus, the peaks of radio signal strength at the Schumann resonance follow a constantly shifting but reasonably predictable schedule.
A very important point to be aware of is that this resonated radio from lightning is a vanishingly small component of the electromagnetic spectrum to which we're all naturally exposed.
The overwhelming source is the sun, blasting the Earth with infrared, visible light, and ultraviolet radiation.
All natural sources from outer space, and even radioactive decay of naturally occurring elements on Earth, produce wide-spectrum radio noise.
Those resonating in the Schumann cavity are only a tiny, tiny part of the spectrum.
Nevertheless, because the Schumann resonance frequencies are defined by the dimensions of the Earth, many New Age proponents and alternative medicine advocates have come to regard 7.83 Hz as some sort of mother earth frequency, asserting the belief that it's related to life on Earth, despite its being so tiny and lost among all the other stronger parts of the electromagnetic spectrum.
Often we find that New Age beliefs are often based more on what seems emotionally satisfying than on sound science.
The most pervasive of all the popular fictions surrounding the Schumann resonance is that it is correlated with the health of the human body.
There are a huge number of products and services sold to enhance health or mood, citing the Schumann resonance as the foundational science.
But before looking at some of these claims in detail, it's noteworthy that neither Schumann resonances, electromagnetic radiation, or the Earth's ionosphere are mentioned in any medical or anatomical textbooks.
There is no detectable or theoretically predicted relationship between either ELF radio or the number 7.83 and the health of the human body.
But let's look at some of the claims.
Many marketers of jewelry that claims to provide health or sports performance benefits cite the Schumann resonance as the science behind their claim.
A notable example is the power balance bracelets.
Tom O'Dowd, formerly the Australian distributor, said that the Mylar hologram resonated at 7.83 Hz.
When the bracelet was placed within the body's natural energy field, the resonance would reset your energy field to that frequency.
Well, there were a lot of problems with that claim.
First of all, 7.83 Hz has a wavelength of about 38,000 kilometers.
This is about the circumference of the Earth, which is why its atmospheric cavity resonates at that frequency.
38,000 kilometers is just a little bit bigger than a one or two centimeter hologram.
There's no way that something that tiny could resonate such an enormous wavelength.
O'Dowd's sales pitch was implausible by a factor of billions to anyone who understood resonance.
This same fact also applies to the human body.
Human beings are so small relative to a radio wavelength of 38,000 kilometers that there's no way our anatomy could detect or interact with such a radio signal in any way.
In a world that can feel overwhelming, spreading thoughtful, evidence-based content is one of the best ways to make a positive impact.
Ask your local public radio station to air the Skeptoid Files, a 30-minute radio-friendly version of Skeptoid that pairs two related episodes promoting real science, true history, and critical thinking.
And in these challenging times for public media, we're offering these broadcasts for free to radio stations, available on the PRX Exchange or directly from Skeptoid Media.
It's an easy ask.
Just send a quick message to your station's programming director.
By helping to bring the Skeptoid files to the airwaves, you'll help promote the essential skills we all need to tell fact from fiction.
Just go to your local station's website, find the programming director's email address, or just their general email address.
You can even use the telephone.
I know that might sound crazy.
It's an old legacy device that allows real-time voice communication.
I know that's weird, but hey, it's an option.
The world can feel chaotic, but you're not powerless.
When you promote critical thinking, you can help your community tell fact from fiction.
And that's how we shape a better future.
In uncertain times, spreading good ideas can make you feel helpful, not helpless.
Let's stand up for reason, truth, and understanding together.
Get them to air the Skeptoid files from Skeptoid Media, available on the PRX Exchange, and they'll know what that is.
Proponents of binaural beats cite the Schumann frequency as well.
These are audio recordings which combine two slightly offset frequencies to produce a third phantom beat frequency that is perceived from the interference of the two.
Here's a common binaural beat recording that produces a beat frequency of 7.83 Hz.
Claims for how this benefits the body are diverse, but most either say something generally similar to what O'Dowd said, or they would claim to change your brain's encephalogram, which they say is a beneficial thing to do.
Brain waves, the fluctuations of current in the brain, as measured at the scalp by an electroencephalogram, can range from near zero up to about 100 Hz during normal activity, with a typical reading near the lower end of the scale.
This happens to overlap 7.83, suggesting the aforementioned pseudoscientific connection between humans and the Schumann resonance.
But with a critical difference.
An audio recording is audio, not radio.
It's the physical oscillation of air molecules, not the quantum electrodynamic oscillation of electrons.
The two have virtually nothing to do with each other.
Audio waves do not affect radio waves, and vice versa.
So by no science that's understood, would we expect an audio tone to cause a brain's activity to change its frequency to match?
There's a complete skeptoid episode on binaural beats that addresses the claims in greater detail and examines some of the research done.
I found one website, earthcalm.ca, just as one example among many, that says, Scientific research has recently determined how the human body receives and uses the important information from the Earth's field.
Seven billion crystalline magnetites in the human brain, in addition to DNA and the pineal gland, are meant to receive guiding information from the band of electromagnetic frequencies that extends from the Earth's crust to the ionosphere, Schumann resonances.
Today, the Earth's field is polluted with man-made frequencies, so the human body instead receives junk produced by AC electricity and wireless technology.
Variations on this specific claim are fairly ubiquitous, that our body's energy fields need to interact with the Schumann resonance, but can't because of all the interference from modern society.
It's all complete and utter nonsense.
Human bodies do not have an energy field.
In fact, there's not even any such thing as an energy field.
Fields are constructs in which some direction or intensity is measured at every point.
Gravity, wind, magnetism, some expression of energy.
Energy is just a measurement.
It doesn't exist on its own as a cloud or a field or some other entity.
The notion that frequencies can interact with the body's energy field is, as the saying goes, so wrong it's not even wrong.
Another really common New Age misconception about the Schumann resonance is that it is the resonant frequency of the Earth.
This is also completely wrong.
Take another listen to Blowing Across the Bottle.
The space inside the bottle resonates at 196 Hz, a G on the musical scale.
But listen when I tap the bottle itself.
The resonant frequency of the glass bottle itself is about 3,520 Hz, which is an A on the musical scale.
Two completely different notes.
That's because the bottle and the space inside are two different things with not necessarily any relationship between them.
Seismic Waves vs Musical Notes 00:03:38
Similarly, there's no reason to expect the Earth's electromagnetic resonant frequency to bear any similarity to the Schumann resonance.
But furthermore, the Earth probably doesn't even have a resonant electromagnetic frequency.
Each of the Earth's many layers is a very poor conductor of radio.
Combined altogether, the Earth easily absorbs just about every frequency it's exposed to.
If you've ever noticed that your car radio cuts out when you drive through a tunnel, you've seen an example of this.
Now the Earth does, of course, conduct low-frequency waves of other types.
Earthquakes are the prime example of this.
The Earth's various layers propagate seismic waves differently, but all quite well.
Seismic waves are shock waves, a physical oscillation of the medium.
Like audio waves, these are unrelated to electromagnetic radio waves.
Each and every major structure within the Earth, such as a massive rock within a continent, a particular layer of magma, etc. does have its own resonant frequency for seismic shock waves.
But there is, definitively, no resonant electromagnetic frequency for the Earth as a whole.
So our major point today is that you should be very skeptical of any product, service, article, website, or merchant who uses the Schumann resonance in any way as part of a sales pitch.
The Earth does not have any particular frequency.
Life on Earth is neither dependent upon nor enhanced by any specific frequency.
Most of these sales pitches are what we in the Brotherhood like to call a word salad.
sciencey sounding language thrown together in such a way as to sound impressive to the layperson.
There's plenty of science-y goodness in understanding why and what the Schumann resonances actually are, without co-opting them to promote nonsense.
