What is an earthing ground?

An earthing ground is a “connection to ground” for static electricity found in a room and around electronic devices. Electronic devices that plug into a wall socket have a grounding path to earth ground provided within a standard wall socket. The static electricity looks for the quickest path to ground which an earthing cable may provide. Occasionally, the earthing cable ground is used for electrically sensitivity people and extra device protection.

An earthing ground is NOT an conductive path for the electromagnetic emissions from laptops, tablets and cell phones. These devices emit Extremely Low Frequency (ELF) or Radio Frequency (RF) EMF radiation emissions. ELF or RF emissions will not travel the conductive path of an earthing ground.

An earthing cable will not provide any shielding protection from EMF radiation. That is what the DefenderShield® is designed to accomplish. There is very little static electricity emitted or accumulated by electronic devices because they typically self-ground. Static electricity poses no imminent health risk, but maybe a slight irritant for the electromagnetic hypersensitive.

What can I use to protect my family from the WiFi router in our home?

The best way to limit your exposure to WiFi is creating distance between yourself and the router. We recommend the router be placed as far a distance away as possible from the main living areas and bedrooms.

We recommend placing your WiFi router at least 10 feet away at a minimum from where you do daily activities.

WiFi uses radio waves and these signals follow what is known as the inverse square law. This means that as you get further away from the source, the intensity of the energy decreases. In the case of a WiFi router, if you were to double your distance from it, you would only be exposed to about a quarter of its energy. Even at a relatively close distance like 10 feet away, the intensity of the the emissions are dramatically reduced.

You may also want to turn off your router when not using it, or use wired Ethernet connections. You may also benefit from using a timer to turn off your router in the evening and back on in the morning.

Is static electricity harmful?

There is very little static electricity emitted or accumulated by electronic devices because they are typically self-ground. This static electricity poses no imminent health risk, but may be a slight irritant for electromagnetic hypersensitive individuals.

What are DC and AC magnetic fields?

Yes. Direct Current (DC) magnetic fields do not vary because the power source is constant. Alternating Current (AC) magnetic fields are created by an alternating power source generated at a given frequency. Almost all house and commercial power is AC, which is at 60 Hz.

Does aluminum foil block electromagnetic fields (EMF)?

Aluminum, the material that tin foil is made of, does conduct RF (Radio Frequency) and as a result, can block wireless EMF. Its effectiveness depends upon how strong the EMF source is and how much foil is used. Effectiveness spans from “reasonably good” to “not so good” depending on those variations. Foil does not block ELF (Extremely Low Frequency).
