We Measured It.
Here’s What We Found.

The Problem Nobody Shows You

You can’t see electromagnetic signals.

Yet your home is full of it — cellular networks pushing data through walls, smart meters reporting to the grid, and dozens of passive electronics radiating all day and night.

Electromagnetic noise is simply energy — radio frequency (RF) radiation emitted by devices as a byproduct of how they communicate. Most of it is low-level. Most of it has been deemed acceptable by regulatory standards designed for acute exposure at high intensities. What those standards don’t address is the question of long-term, low-level, cumulative ambient load — the environment you actually live in.

That’s the gap emGuarde was built for.

What the Spectrum Shows

Left: Without emGuarde — a broad, messy peak at ~72 MHz with noise bleeding across neighboring frequencies.

Right: With emGuarde active — the same peak locks to a precise 72 MHz. Signal sharpens. Background noise drops.

emGuarde works like a tuning fork — it introduces precisely calibrated frequencies that bring that chaos into alignment.

How EMF affects our biology

We wanted to answer a simple question: what does 30 minutes of phone use do to your blood? Does emGuarde make a difference?

How We Tested

The setup was straightforward. We took a baseline blood sample from the subject at rest, with no recent device use. Then the subject used a smartphone at close range for 30 continuous minutes, and we took a second sample immediately after. Finally, we repeated the same 30-minute session — this time with emGuarde active in the environment — and took a third sample. Same subject, same session structure, same operator. Everything held constant except the one variable we were testing.

Observation — Without emGuarde

After phone use, the blood sample showed signs of Rouleaux formation — red blood cells clumping together like a roll of coins instead of moving freely on their own. Rouleaux is a known pattern in microscopy, documented in peer-reviewed literature as a response to environmental and physiological stressors.

Observation — With emGuarde

After the same phone use protocol, the blood cells looked essentially normal — individual, freely separated, and consistent with the pre-exposure baseline.

What This Means

In this controlled test, emGuarde’s presence correlated with a measurably different outcome in red blood cell morphology following the same exposure protocol.

Why It Matters

Researchers have been studying what chronic exposure to electromagnetic noise may do to the body. Some studies have found measurable effects on our sleep, cellular stress, sperm health and more. Read our journal here.

We are taking a precautionary approach grounded in wave physics: you don’t have to wait for the science to be fully settled to take a simple step toward a cleaner electromagnetic environment at home.

Controlled testing. Not a clinical trial. Individual results may vary. emGuarde is not a medical device and makes no therapeutic claims. Testing conducted with Universiti Sains Malaysia represents instrumentation-based RF measurement under controlled conditions. Blood microscopy observations are from limited controlled testing and should not be interpreted as clinical evidence. Consult a qualified healthcare professional for any health-related concerns.
