Schumann Resonance Explained: The Earth's 7.83 Hz Rhythm
The Earth has a pulse. Lightning around the planet creates natural electromagnetic resonances, the strongest near 7.83 Hz, known as the Schumann resonance. Our bodies are electrical too, and researchers are exploring how living systems respond to fields like these. The BIO PAD and BIO POD are inspired by that relationship.
In this piece we explore the Schumann resonance, the emerging science of bioelectromagnetism, the plasma air treatment inside the BIO PAD, and what is, and isn't, yet known.
In short
Schumann resonances are a measurable part of the Earth's atmosphere, and the body runs on electrical signals. The BIO PAD and BIO POD add a pulsed field modelled on the Earth's rhythm to the space around you; the BIO PAD also treats the air using plasma. How living systems respond to fields like these is a developing area of research.
What Is the Schumann Resonance?
The Earth is surrounded by naturally occurring electromagnetic fields. Among them are the Schumann resonances, generated mainly by lightning within the cavity between the Earth's surface and the ionosphere.
The fundamental resonance sits near 7.83 Hz, an extremely low frequency, meaning the field oscillates about 7.83 times every second.

Is the Human Body Electrical?
Bioelectromagnetism is the study of the electrical and magnetic properties of living systems. The body is electrically active at every level.
An electrical body
01
Nerves
Impulses travel as ions such as sodium, potassium and calcium cross cell membranes.
02
Heart
Electrical signals coordinate every beat, measured with an ECG.
03
Brain
Rhythmic electrical patterns tied to attention and sleep, measured with an EEG.
Brain rhythms are grouped into delta, theta, alpha, beta and gamma bands. The Schumann frequency sits close to the transition between theta and alpha, and that similarity has inspired hypotheses about how environmental fields and the nervous system might interact.
Life is electrical.
The question is how it responds to the fields around it.
Can an External Field Influence the Body?
Entrainment, where one oscillating system influences the timing of another, is a real physical and biological phenomenon. Demonstrating it takes more than matching frequencies, though. The strength, geometry, waveform and duration of a signal all matter.
Medical technologies such as transcranial magnetic stimulation show that controlled magnetic pulses can affect brain tissue. That doesn't by itself establish that a small consumer device has comparable effects. Cell State's proposed links to alpha waves, focus and relaxation haven't yet been tested in independent human studies of these devices.
Does a Schumann Device Block EMF?
Generating a field is different from shielding one. A device emitting a Schumann-like frequency doesn't block Wi-Fi, mobile signals or other radiofrequency emissions. In a world full of man-made EMF, it adds a field modelled on the Earth's own natural rhythm to the space around you.

BIO POD
The Earth's rhythm, wherever you go. A portable pulsed field modelled on the 7.83 Hz Schumann resonance, for home, office, car and travel.
How Does Plasma Air Treatment Work?
Plasma is an ionised state of matter containing charged particles and, depending on the system, chemically reactive species. When electrical energy interacts with air, it can create ions and reactive molecules, including hydroxyl radicals, which can damage the proteins, membranes and genetic material of airborne microbes.
Simply put, plasma technology uses electricity to create chemical reactions in the surrounding air. Cell State describes the BIO PAD as generating ions from atmospheric oxygen and moisture, with a treatment range of over 20 metres. Plasma chemistry is established science; real-world performance depends on the device, the room and the air, and we've asked Cell State for independent testing of performance and ozone output.

BIO PAD
The Earth's natural rhythm and cleaner air from one quiet plug-in device, with no filters to replace.
BIO PAD or BIO POD?
BIO PAD
An Earth-frequency field plus plasma air treatment. Best for a room you live or work in.
BIO POD
The Earth-frequency field in a portable size. Best for moving between home, work, car and travel.
Final Thoughts
These devices sit where environmental engineering meets bioelectromagnetic research. The plasma function offers a physically plausible way to treat the air; the electromagnetic function reflects a developing field of research into how living systems respond to the fields around them. Two distinct ideas, each worth understanding on its own terms.

Frequently Asked Questions
What is the Schumann resonance?
A set of natural electromagnetic resonances in the cavity between the Earth's surface and the ionosphere, generated mainly by lightning. The fundamental resonance sits near 7.83 Hz.
What does the BIO POD do?
It produces a pulsed low-frequency magnetic field modelled on the Schumann resonance. Cell State advertises a field up to 40 metres in diameter.
What's the difference between the BIO PAD and BIO POD?
The BIO PAD combines the Earth-frequency field with plasma air treatment. The BIO POD is the portable, field-only version.
Does the BIO POD protect against EMF?
It doesn't block Wi-Fi or phone signals. It adds a field modelled on the Earth's natural rhythm to the space around you.
Is the science settled?
Schumann resonances and the body's electrical activity are well established. How the body responds to small external fields like these is still being researched.
