What is EMF?
Invisible Waves – Measurable Protection
We live in a connected world. Mobile phones, Wi-Fi, Bluetooth, smart devices and wireless networks have transformed the way we communicate, work and live. Behind these technologies are electromagnetic fields – EMF. They are invisible, but they are an increasingly present part of our everyday environment.
You cannot see them.
But you can measure them.
And you can reduce them.
Where Does EMF Come From?
Electromagnetic fields occur naturally, but they are also generated by electrical and wireless technologies. In our everyday environment, common sources of radiofrequency electromagnetic fields include:
Mobile Networks · Wi-Fi · Bluetooth · 4G & 5G · Smart Devices · Radio & TV Transmitters
Every wireless connection relies on electromagnetic waves to transmit information.
What Are Microwaves?
The term microwaves describes part of the radiofrequency electromagnetic spectrum.
Many modern communication technologies operate within microwave frequency ranges – including Wi-Fi and certain mobile communication frequencies.
Unlike ionizing radiation such as X-rays, radiofrequency electromagnetic fields are non-ionizing. They do not have enough energy to ionize atoms or directly damage DNA in the way ionizing radiation can.
Why Reduce Exposure?
International exposure limits are designed to protect against established adverse effects of radiofrequency electromagnetic fields
For people who prefer to take a precautionary approach, reducing unnecessary exposure in the places where they spend many hours – particularly bedrooms and living areas – can be a conscious personal choice.
Swiss Shield® makes that choice possible without giving up the benefits of modern technology.
You can't switch off the modern world.
But you can shape your own environment.
Exposure Is Not the Same Everywhere
The electromagnetic environment around us depends on many factors:
• Distance from the source
• Signal strength
• Frequency
• Duration of exposure
• Building construction
• Number of wireless devices
• Nearby transmitters and antennas
This means that two homes – or even two rooms in the same home – can have very different electromagnetic environments.
You Cannot See It – But You Can Measure It
Professional measuring equipment can determine the strength and frequency of radiofrequency electromagnetic fields within a room.
This makes EMF different from many other invisible environmental factors:
It can be measured.
It can be understood.
And it can be reduced.
