Blushield Dairy Cow Study:
Somatic Cell Count Test Results
By alternating a Blushield on and off in a dairy barn over several months, the somatic cell count of the herd's milk fell from an average of 360 (peaking at 420) without the device to an average of 140 (as low as 120) with it - consistently dropping within about 10 days of plugging in, while other stress markers disappeared as well. Because cows cannot have psychosomatic cell-count changes, these results point to a real physiological effect.
What Is a Somatic Cell Count?
When milk is received at the dairy processing plant, it is automatically checked for the level of somatic cells present. All milk contains some level of somatic cells; the level present is an indication of the quality of the milk and the health of the cows. Whenever a cow is subjected to stress - such as an injury or disease - the cell count rises. This is Mother Nature in action: white blood cells are created to fight off the stress.
The Test and Results
We monitored the somatic cell count in the entire milking herd for several months, alternating between the Blushield being plugged into the dairy barn and removed from it. The results were very consistent:
- Without the Blushield: the highest level reached was 420, with an average reading of 360.
- With the Blushield plugged in: the lowest reading was 120, with an average of 140.
Obviously, the cows do not have cell-count changes due to psychosomatic factors.
Background: A Herd Near a TV Mast
Some background on the EMF exposure of these cows: this particular herd was pastured in New Zealand near a TV mast that was put up in the 1970s. Before the mast went up, cows grazing in that area were generally happy and healthy. After it was installed, the farmers had to start putting out salt blocks for the cows - indicative of higher levels of biological stress burning through minerals much more quickly. There were also more instances of mastitis in the dairy cows, and the somatic cell count of the milk started increasing once the TV mast was installed in the area.
The testing with Blushield was done around the year 2000. The somatic cell count of the herd's milk consistently went down within about 10 days of plugging in the Blushield devices, and their other previous stress markers went away as well.
By alternating a Blushield on and off in a dairy barn over several months, the milk's somatic cell count averaged 360 (peaking at 420) without the device and 140 (as low as 120) with it - consistently dropping within about 10 days of plugging in, with other stress markers disappearing as well.
Somatic cells (white blood cells) are naturally present in all milk, and their level indicates milk quality and cow health. When a cow is stressed by injury or disease, white blood cells are produced to fight the stress, so the count rises - making it a useful marker of herd well-being.
Cows cannot experience psychosomatic (placebo-type) changes in cell count, so the consistent drop when the Blushield was plugged in, and rise when it was removed, points to a genuine physiological effect rather than expectation.
The herd was pastured in New Zealand near a TV mast erected in the 1970s. After it went up, farmers had to provide salt blocks (a sign of biological stress depleting minerals faster), mastitis cases increased, and milk somatic cell counts rose.
The Blushield testing was carried out around the year 2000.

Frequently asked questions
Invisible forces are part of modern life, but their impact doesn’t have to define you. Blushield works quietly in the background, supporting a more stable, balanced internal state so you can focus, rest, and perform at your best.
It doesn't block or shield EMF. Instead, Blushield is designed to support the body's natural response to everyday electromagnetic exposure. By focusing on biological support rather than altering environmental signals, it takes a different approach to EMF protection.
Plug-in units (Premium, Ultimate, Phi) cover your home. Portables cover you when you leave it. Most people start with one of each: a plug-in for the house and a portable for travel, work, and the car. If you're not sure, use our Find Your Device tool or message us.
30-day limited money-back guarantee on every device (restocking fee applies - see our full return policy). Stationary and portable units carry a 1-year warranty. If anything extends past that, contact us.
Yes. EMF meters measure intensity, not biological impact. Even low-level exposure from Wi-Fi, Bluetooth, smart meters, cell towers, and nearby homes accumulates 24/7. Blushield works on the body's response, so it helps regardless of what a meter reads.
Some people feel calmer or sleep better within the first night. For others it's a few weeks of gradual change - better focus, deeper sleep, and less fatigue. A small number notice a short adjustment period as the body recalibrates. Everyone responds differently, so give it time to become part of your daily environment and let the benefits build naturally.
Yes. Blushield is built on decades of research into how the body responds to coherent vs. incoherent electromagnetic signals. We have independent studies, HRV data, and live-blood analyses on our Science page. We don't make medical claims. We point you to the data and let you decide.
