DefenderPad® Laptop Radiation & Heat Shield

How does the DefenderPad® protect me from harmful laptop and heat radiation?

The heat emitted from the bottom of a laptop can reach temperatures as high as 115° Fahrenheit (46.11° Celsius). Laptops tend to overheat because there is not a proper path for heat ventilation, intake air vents may be clogged with dust, or the laptop no longer operates as designed because of age.

The DefenderPad® does not have cooling fans, however, the thermally-resistive surface material on the top of the DefenderPad® allows the heat produced by laptops to flow away from the laptop and prevents all downward air flow from reaching the body. The DefenderPad® provides a clear venting heat path which keeps the laptop operating without overheating. This kind of air flow pattern significantly reduces the chances of your laptop overheating while also reducing your exposure to potentially dangerous heat levels. In the process of diverting this heat, the DefenderPad® absorbs some portion of the heat and, although warm, the heat on the bottom of the DefenderPad® is well within safety limits.

Permalink

How Do I Use the DefenderPad® Laptop Shield?

Place the DefenderPad® on your lap with the grippy, rubber surface facing upward and then place your laptop or tablet on top of it. The DefenderPad® blocks EMF emissions moving in the downward direction of the electronic device.

Permalink

If I use a DefenderPad®, does my laptop emit more dangerous emissions? Will they reflect back at me?

No. When using the DefenderPad® underneath a laptop, EMF radiation emitted from the device does not increase. The laptop emissions that flow in the downward direction from the laptop are absorbed and dissipated by the shielding materials and are never reflected back toward you.

Permalink

Does the DefenderPad® reduce or block a wireless WiFi signal or router connectivity?

No. WiFi continues to work as designed and the transmitted signal direction is not altered or blocked in any way.

Permalink

Can the DefenderPad® be used on a desk?

Questions About EMF Radiation:

Electromagnetic Radiation (EMF) Information

Is a WiFi the same as microwave and a Radio Frequency (RF) radiation?

A WiFi signal transmits and receives information between your your electronic device and router to connect to the internet. WiFi, short for wireless fidelity, refers to a signal which operated at a few different frequencies.

Generally speaking WiFi is typically used as a standalone term. The term microwave is a reference to a class of waves, referenced as a microwave range or spectrum of frequencies that the WiFi signal operates. For example, the WiFi signal from your laptop is often transmitted at 2.4 GHz, a frequency found within the microwave range, or spectrum of 300 MHz to 300 GHz. This 2.4 GHz frequency is also within the same spectrum of what is called the Radio Frequency (RF) range, 3 KHz – 300 GHz. As you may notice, the RF is simply a slightly more broad frequency spectrum than the microwave range. All of the terms are often used interchangeably.

Permalink

What are low frequency magnetic fields?

Electric fields occur when positive or negative electrical charges are present and apply forces on other charges within the fields. The fields and their strength are measured in volts per meter (V/m). Active electrical wires produce electric fields, as do almost all electric powered devices. The field exists even when there is no current flowing. When the voltage increases, so does electric field surrounding the device. When moving away from the source of the field, the field strength is reduced.

Magnetic fields are created from electric charges. Their strength is measured in amperes per meter (A/m). Electromagnetic Fields (EMFs) also have related measurements which identify the flux density, expressed in microtesla, µT. When current is increased, the strength of the magnetic field increases. Magnetic fields are not commonly blocked with everyday materials.

Permalink

What is an Electromagnetic Field (EMF)?

Electromagnetic Fields (EMF) are omni-directional (moves in all directions) waves generated from electrically powered devices in the form of an electrical energy with a magnetic field. EMFs are also known as Electromagnetic Radiation (EMR).

Moving closer to the source of the waves increases the magnetic field intensity. A magnetic field cannot be felt, seen, or heard. Although the earth creates a magnetic field, EMFs also emanate from electrical devices such as computers, tablets, cellphones, radios, motors, home appliances, transformers, and electric power lines etc.

What is the difference between Non-Ionizing and Ionizing radiation?

Non-Ionizing radiation does not carry enough energy to break molecular bonds and ionize atoms. Example of non-ionizing are Extremely Low Frequency (ELF) and Radio Frequency (RF) radiation.

Ionizing radiation is the type of radiation that carries enough energy to break bonds between molecules and ionize atoms. Examples of Ionizing radiation are the gamma rays emitted by radioactive materials, cosmic rays, and X-rays.

Permalink

What is the difference between Radio Frequency (RF) versus Extremely Low Frequency (ELF) shielding?

Radio Frequency (RF) shielding is the reduction or elimination of high frequency signals up to 5 GHz. Materials shield RF frequencies by creating high conductivity with little or no magnetic permeability.

Extremely Low Frequency (ELF) shields are highly permeable. ELF shields attract magnetic fields and divert the energy through them.

How Do Electronic Devices Produce Electromagnetic Radiation (EMFs)?

Types of Electromagnetic Radiation (EMFs) & How They are Created

Electronics all fundamentally work the same way. They use an electric current passing through a circuit to perform a function.

Electricity is an energy which must be harnessed to make it do what we want it to do. The electronic circuit is the basic unit through which electricity is transmitted. Scientists and engineers developed various ways to harness the power of electricity for humanity.

Extremely Low Frequency (ELF) EMFs

Electronic devices offer computing functions, phone calls, Internet connections, light up panels, and so many more capabilities.

As a by-product of these functions operating, an electric current is generated that flows within and between components creating EMFs. This type of radiation is also known as Extremely Low Frequency (ELF).

Radio Frequency (RF) EMFs

Many electronic devices also communicate outside the device, transmitting communication signals from your device to other devices so you can talk on the phone or connect to the Internet via WiFi. These signals are called Radio Frequency (RF) signals or Microwave (MW) signals.

RF signals can be transmitted at many different frequencies and power levels. A cell phone signal, for example, can travel several miles, while a WiFi signal transmits less than 100 feet.

These varying distance capabilities require the electronics to generate differing power levels in order to accommodate the distances.

What Does an Electromagnetic Field Look Like?

As a result of electrons moving, electricity is generated in one direction and magnetism in another. This results in energy moving in two directions.

The energy of the electricity moves on an x-axis, and perpendicularly at a 90 degree angle, a magnetic field is generated alongside it.

Laptop EMF Radiation Emissions

What health problems can be caused by using a laptop directly on your lap?

Direct exposure to Extremely Low Frequency (ELF), Radio Frequency (RF) and Heat Radiation emissions can cause numerous health risks such as:

  • Fertility problems in men and women
  • DNA fragmentation (irreversible changes to the genetic code)
  • Toasted Skin Syndrome (Erythema ab igne), burns and rashes
  • Other serious health concerns

Permalink

When are laptop EMF radiation emissions most harmful?

Laptops present the greatest potential for health risks when used directly against the body. With just one foot or more of distance between your laptop and your body, the most critical health risks of EMF emissions are substantially reduced by about 80%.

Permalink

Why is laptop radiation such a big deal now and it wasn’t 20 years ago?

Twenty years ago computers were big and bulky. Once you put them down on your desk or on the floor, there was no need to move them. They emitted EMF radiation, but were relatively safe, because they were primarily used a safe distance away from the body.

Today, computers and other devices are extremely portable and can fit on your lap or in the palm of your hand. Today’s devices have many times more computing power, and are used much closer to the body, thus creating health risks that did not exist 20 years ago.

Permalink

How can heat from a laptop harm me?

Your laptop can get very hot and burn and/or irritate your skin, create fertility problems, and modify body cells, as well as cause other health issues.

Permalink

Does radiation emit from the screen, keyboard and sides of laptops?

Radiation is generated by a laptop in all directions: bottom, top and sides. Radiation is considered most dangerous when in direct contact with the body, particularly when on the lap. The most harmful radiation emissions are emitted from the bottom of the laptop and travel in a downward direction. The DefenderPad® is designed to shield these emissions from touching the body.

The screen and sides of a laptop tend to emit less radiation than the bottom. The radiation levels of the screen, keyboard and sides of a laptop are considered acceptable, low-rise emissions. As a rule of thumb, if you are one foot away from the source of the emissions, the dangers are greatly reduced. Even moving a laptop a few inches away from the lap reduces exposure to potentially harmful radiation.

Permalink

Tablet EMF Radiation Emissions

Can I develop health problems from using a tablet or iPad®?

Yes. Close exposure to tablet EMF radiation emissions can be a health risk. Tablet computers emit two types of EMF: Extremely Low Frequency (ELF) radiation and Radio Frequency (RF) radiation which includes WiFi, Bluetooth and cellular signals (if supported by your tablet) up to 10 GHz. DefenderShield® technology blocks up to 99% of EMF radiation from 0-10 GHz, which encompasses almost all frequencies used in the current 5G network.

More and more, particularly in recent years, scientific studies have confirmed that EMF radiation can adversely alter the biological operations of the body. In more serious cases, exposure to EMF may create tumors, reduce sperm count, lead to cancer and other serious health concerns.

Permalink

Where does the radiation emit from a tablet or iPad?

Radiation is generated by a tablet in all directions; back, screen and sides, with the most radiation emitted from the back and top of the tablet where the Radio Frequency (RF) transmitters are located. Exposure to radiation from the screen of a tablet is reduced because it is not touching the body directly.

As a rule of thumb, when one foot away from the emitting source the dangers of these emissions are significantly reduced by as much as 80%.

Permalink

Permalink

How far away from your bed should your phone be when you sleep?

We suggest keeping your phone at least 4 feet away from your bed when you sleep.

Placing your phone a few feet away will considerably reduce the amount of EMF radiation reaching your body. This also applies to tablets and laptops.

Permalink

What are the health risks related to using a cell phone?

Cell phones emit Electromagnetic Fields (EMF) and direct exposure to these emissions can be a health risk. There are two types of EMF radiation emitted from cell phones: Extremely Low Frequency (ELF) radiation which is emitted from all electrical devices, and Radio Frequency (RF) radiation which includes cellular signals, WiFi and Bluetooth. More and more, particularly in recent years, scientific studies have confirmed that EMF exposure can adversely impact the biological operations of the body. In more serious cases, exposure to EMFs can lead to tumors, reduce sperm count and other serious health concerns.

Cell phone radiation emissions present the greatest potential health risks when directly touching the body, especially the head, breasts and reproductive organs. Moving your cell phone away from your body just a few inches reduces health risks. When a cell phone is moved at least one foot away from the head or body, cell phone radiation is reduced by as much as 80%.

If your phone accesses the 5G network (iPhone 12 series, Samsung Galaxy S21, Samsung Galaxy Note 20 Ultra, etc.) there is most likely a way to turn off 5G connections, put in place because your 5G signal might be slower than 4G/3G networks, and it can really drain your battery. When your iPhone is in low power mode, it will only connect to the 5G network for streaming 4k video. Apple outlines other ways you can disable the 5G network in your settings. Just navigate to Settings, Cellular, Cellular Data Options, and select Voice & Data. You can turn on LTE, which will use only 4G LTE even when 5G is available. You can also switch on low data mode, which helps reduce WiFi and cellular-data usage by pausing automatic updates and background tasks. For Samsung 5G phones, you should be able to navigate to Settings, Connections, Mobile Networks, then select Network Mode, where you can disable 5G by tapping LTE/3G/2G (auto connect), 4G/3G (auto connect), 3G only or 2G only. You can also use our DefenderShield iPhone 12 Series and Universal Series EMF Protection Cases that come with our BRAND NEW Ultra Armor™ Technology, the only shielding technology that can block the entire 5G spectrum.

Why is cell phone radiation such a big deal now and it wasn’t 20 years ago?

Twenty years ago, computers and telephones were big and bulky. Computers were placed on the floor and weren’t designed to move while phones were placed in a stationary base connected by cords and wires. They both emitted Electromagnetic Fields (EMFs), but were relatively safe because they were used a safe distance away from the body.

Today, the computer and phone have merged into one device that fits in the palm of your hand. A smartphone is essentially a small computer, yet has many times the computing power of traditional computers. When turned on in your pocket or used against your head, the cell phone touches some of the most sensitive parts of the body. Now, cell phones are now used much closer to the body and for longer periods of time, creating more health risks than in the past.

Do cell phones emit radiation when using WiFi?

Yes. By default, WiFi is enabled on cell phones, so unless you turn this capability off, your WiFi processor will continue to send out wireless radio frequency (RF) signals in search of a WiFi router. This means even if you are not connected, your phone is emitting radiation in its search to connect to a router. When you are connected, your phone is still emitting radiation to maintain the signal, by sending constant pings to the router and back. We advise turning off your WiFi processor in settings when you are not actively searching for a WiFi signal.

Which phone has the highest radiation emissions?

All cellular devices are given a SAR (Specific Absorption Rate) rating, that measures how much RF energy is absorbed by a user’s head and body. This is measured in watts per kilogram, and is the maximum absorption the phone is capable of. With the hundred of different phone models, with new ones coming out all the time, it’s hard to say what phone has the highest SAR rating. Generally, iPhones have skewed higher on SAR ratings when compared with other phones. Samsung phones have a reputation for scoring low SAR ratings. We recommend checking your devices specific SAR rating, which can be checked in the phone’s user manual as well as on the manufacturer’s website and the FCC website.

What level of SAR is safe?

SAR stands for Specific Absorption Rate, and is the rate that cell phone radiation emissions are absorbed into the body. The FCC states that an exposure limit of 1.6 watts per kilogram is an acceptable level. The limit in the European Union is 2.0 W/kg averaged over a larger mass. While this is the standard that has been accepted as safe, it is based on the assumption that EMF can only create thermal damage with chronic exposure. This ignores research showing that other biological effects are evident at lower levels of radiation exposure, below levels necessary for thermal heating. If these standards were to be updated, they might show a lower limit. For now, SAR thermal absorption standards are helpful for comparing radiation emissions between different devices, but it by no means establishes an absolute safe level for these emissions.

What types of EMF radiation does a cell phone produce?

When you use a cell phone directly against your head or next to your body, it exposes you to potentially harmful EMF radiation emission levels. These emissions include:

  1. Extremely Low Frequency (ELF) Radiation – coming from the battery powering your phone
  2. Radio Frequency (RF) Radiation – coming from your cellular data signals, your WiFi processor, and your Bluetooth processor
  3. Heat Radiation – a by-product of ELF and RF emissions

How do I know if I have 5G on my phone?

To access the 5G network, your device first needs to be either operating under a cellular data contract or using a fixed wireless cable system in your home. This rules out most tablets, laptops, WiFi routers, and other devices that are separate from your cellular plan. For devices that use cellular data, to connect to 5G they must have a 5G modem built into the device (some 5G trials and testing used separate modems that connected to your phone for 5G access). Integrated 5G modems didn’t come out until 2020, and are only in select phones (iPhone 12 series, Samsung Galaxy S21, Samsung Galaxy Note 20 Ultra, etc.). If you have an older phone model, your phone is not capable of connecting to the 5G network–and no, 5GE is not the 5G network, but instead a 4G LTE advanced signal that was called 5GE (5G Evolution) for marketing purposes. If your phone or fixed wireless system does connect to the 5G network, then it can access frequencies up to 100 GHz. However, the higher the frequency, the less distance the signal can travel, so carriers are mostly utilizing frequencies under 6 GHz (classified as low-band and mid-band) and rarely use high-band frequencies, also called millimeter waves.

Questions About EMF Health Effects & Protection:

EMF Health Effects

I am hypersensitive to EMF radiation. Can I be affected by my wireless keyboard and mouse?

Wireless keyboards and mice communicate via Bluetooth (or similar) technology. Although Bluetooth is a relatively low level of EMF radiation, it can affect the electrically hypersensitive, especially at close distances. However, wireless keyboards and mice are more of an irritant than an imminent health risk.

How does radiation affect male fertility?

Radiation can affect sperm motility and vitality, and cause DNA fragmentation. As an example, in one Argentinian study, scientists studied the effect of laptop Radio Frequency (RF) radiation and WiFi on human male sperm.

  • 25% of the sperm was no longer active compared to 14% from sperm samples stored at the same temperature over the same time period and away from the source of EMF.
  • 25% of the sperm was no longer active compared to 14% from sperm samples stored at the same temperature over the same time period and away from the source of EMF.

Can 5G harm you? Is 5G safe?

5G is the fifth generation cellular network. It offers frequencies 20 times faster and data transfer rates up to 100 times faster than 4G. Scientists are concerned that 5G’s higher frequency will not only exacerbate the already researched health effects of 4G, but create new problems of its own that won’t be seen until 5G is already in place. It’s shorter wavelength means that it won’t travel as far, and cannot penetrate our skin as deeply. However, the increased number of cell towers needed to support this network will definitely mean more exposure to our bodies, and a study showed that while the depth of penetration was less, the absorption rate, or SAR, was higher for the skin. 5G uses different technologies than previous networks that might make it more harmful even if it can’t travel as far. The coverage is beam-based in 5G, not cell based. Its rapid pulsations are more biologically active and can cause disease at a faster rate.

Besides the health effects on humans, 5G could spell out potential disaster for bees, small animals, and crops, which might be much more affected by an artificial MMW frequency. It could also be trouble for international security, weather forecasting, and personal data privacy. Read more about 5G HERE.

How do I know if I have EMF sensitivity? What are symptoms?

EHS, or Electromagnetic Hypersensitivity Syndrome, is not currently a proper medical diagnosis in the U.S., but it is recognized by numerous organizations around the world. This exposure has been linked to ringing in the ears, tingling or burning skin, rashes, fatigue, concentration difficulties and a foggy brain, dizziness, nausea, headaches, and body aches. Extreme radio frequency (RF) exposure can also produce severe illness that mimics MS.

If you think you suffer from EHS, there are easy ways you can reduce your exposure and you can see if that helps your symptoms.

Do different forms of Electromagnetic Fields (EMFs) have different health concerns?

An Electromagnetic Field (EMF) is defined by the frequency and corresponding wavelength. The frequency is expressed as cycles per second, or the number of oscillations. The corresponding term, wavelength, is the distance between each of the waves. It is also true that the higher the frequency, the shorter the wavelength. The human body reacts in different ways depending on the EMF frequency, and a higher frequency doesn’t necessarily mean that frequency is more harmful to the body. Devices and wireless signals emit frequency levels at the lower end of the electromagnetic spectrum, from 0 Hertz (Hz) to 100 Gigahertz (GHz). As the frequency level increases, this yields a higher absorption (SAR level) but a lower penetration into the body. This means that as frequency levels change, health concerns change.

Can I develop health problems from using a tablet or iPad®?

Yes. Close exposure to tablet EMF radiation emissions can be a health risk. Tablet computers emit two types of EMF: Extremely Low Frequency (ELF) radiation and Radio Frequency (RF) radiation which includes WiFi, Bluetooth and cellular signals (if supported by your tablet) up to 10 GHz. DefenderShield® technology blocks up to 99% of EMF radiation from 0-10 GHz, which encompasses almost all frequencies used in the current 5G network.

More and more, particularly in recent years, scientific studies have confirmed that EMF radiation can adversely alter the biological operations of the body. In more serious cases, exposure to EMF may create tumors, reduce sperm count, lead to cancer and other serious health concerns.

What are the health risks related to using a cell phone?

Cell phones emit Electromagnetic Fields (EMF) and direct exposure to these emissions can be a health risk. There are two types of EMF radiation emitted from cell phones: Extremely Low Frequency (ELF) radiation which is emitted from all electrical devices, and Radio Frequency (RF) radiation which includes cellular signals, WiFi and Bluetooth. More and more, particularly in recent years, scientific studies have confirmed that EMF exposure can adversely impact the biological operations of the body. In more serious cases, exposure to EMFs can lead to tumors, reduce sperm count and other serious health concerns.

Cell phone radiation emissions present the greatest potential health risks when directly touching the body, especially the head, breasts and reproductive organs. Moving your cell phone away from your body just a few inches reduces health risks. When a cell phone is moved at least one foot away from the head or body, cell phone radiation is reduced by as much as 80%.

When are EMF radiation emissions most harmful?

EMF radiation emissions coming from your cell phone, tablet, laptop, WiFi router, and other devices present the greatest potential health risks when directly touching the body, especially the head, breasts and reproductive organs. This is due to your body being a conductor. Moving your device away from your body, even by just a few inches, can exponentially reduce the health risks. As a rule of thumb, when a cell phone is moved at least one foot away from the head or body, cell phone radiation is reduced by 80%. When a device is 4 feet away, that exposure drops by 98%.

What are safe levels of Extremely Low Frequency (ELF) Electromagnetic Radiation (EMR) and Radio Frequency (RF) Electromagnetic Radiation (EMR) exposure?

Health experts recommend limiting Extremely Low Frequency (ELF) Electromagnetic Radiation (EMR) exposure to below 2-4 milliGauss (mG) and Radio Frequency (RF) exposure to under .6 volts per meter (V/m). Emissions from laptops and tablets are typically 4-12x that amount.

Does turning off WiFi reduce radiation?

Turning off WiFi will reduce wireless radio frequency (RF) EMF radiation. However, make sure to turn off your WiFi router along with disabling the WiFi processor on your mobile devices. This is especially important at night, when you should either turn your router off or sleep with it at least 12 feet away. While your router emits EMF at a high power level (to travel across your house), your smart phone or tablet is constantly sending out signals to search for and connect to a nearby router, even if there aren’t any powered on nearby. So while turning off your WiFi is helpful if you are within 12 feet of the router, it’s not doing much if your phone and other devices are still right next to you sending out RF signals. Read this blog for more information on WiFi routers.

Does airplane mode eliminate EMF radiation?

Airplane mode prevents your device from searching for a wireless signal, eliminating radio frequency (RF) EMF radiation emitting from your device. You can still manually turn on your WiFi processor while in airplane mode, which will emit some RF to connect to the Internet. However, since cellular and Bluetooth signals remain off, your exposure to RF emissions is reduced. However, while RF emissions can be eliminated in airplane mode, Extremely Low Frequency (ELF) emissions still emit from your device, as long as it is plugged in or uses a battery (even when it’s off!).

Can Orgonite protect from EMF radiation?

Orgonite is a man-made metaphysical substance that can be crafted from resinmetal shavings, and quartz. It is said to balance bio-energy, or a subtle life energy connecting and emitted by all living things. It is said to take in bad energy and replace it with good energy. This energy, Orgone, has not been able to be measured by scientific instruments (since it was first claimed to be measured by Wilhelm Reich, a student of Freud). Claims of decreased sensitivity to EMF radiation come from Orgonite sellers and users, as the rock can “recycle the negative EMF energy.” However, this transformation of energy doesn’t have a scientific backing, and there is no substantiated evidence of it’s efficacy. While we support holistic methods for detoxifying your body, even if Orgonite’s claims are true, it is not able to completely block EMF radiation from entering your body.

What is the best EMF protection for cell phones?

Turning off your phone, or turning off Wi-Fi and Bluetooth when not in use can reduce EMF frequencies that are emitting from your phone. Keeping your cell phone away from your head when possible and distancing it from your body can reduce the amount of EMF frequencies that could otherwise affect vulnerable organs. DefenderShield EMF Blocking Cases and other EMF gear can form a physical shield that is scientifically engineered to block EMF frequencies. If you place the shield in between you and your cell phone or other mobile device, 99% of the frequencies hitting the shield will be blocked from direct skin contact with your body. Stickers, pendants, stones, and other forms of EMF protection have no scientific basis, and are not able to be measured by scientific instruments.

How can radio frequency (RF) exposure be reduced?

Radio frequency radiation, or RF, is a type of EMF radiation coming from wireless devices and networks. It refers to any signal being transmitted through the air, and includes cellular data, WiFi, and Bluetooth. To reduce these signals in your everyday life, try turning off devices when you aren’t using them, using airplane mode whenever possible on your phone, unplugging routers and using wired Ethernet cables to connect to your computer, TV, or other wireless devices. Since RF exposure comes from wireless connections, wire everything that you can to reduce RF exposure. This includes speakers, keyboards, gaming controllers, monitors, etc. Additionally, DefenderShield EMF Protection Products all block RF frequencies when work, school or life demands screen time.

What material can block EMF?

EMF radiation is a range of electromagnetic frequencies coming from electronic devices. It includes wireless radio frequency (RF) radiation, which ranges from 300 Hz up to 100 GHz, and extremely low frequency (ELF) radiation, which ranges from 0-300 Hz. Many materials are capable of conducting wireless radiation (RF), including silver, copper, aluminum, and other metals. However, they all have different properties, and conduct different frequencies of EMF differently. Aluminum, or tin, is a pretty effective and affordable option for conducting EMF. ELF’s extremely long wavelength means it can go through materials that RF cannot. DefenderShield’s Advanced Technology Shielding contains multiple alloys and materials that can absorb, conduct, and dissipate EMF emissions, with many products capable of blocking ELF as well as RF. Our shielding prevents reflection of conducted waves to make it the safest and best shielding available.

How do I reduce EMF radiation in my body?

While there are a number of ways to reduce EMF radiation in your environment to reduce your exposure, there are also many ways to detox your body from EMF and prevent EMF from affecting you. Grounding, or connecting your conductive body to the Earth or a floating ground, can help clear your body of positive ions, also called free radicals, which are produced excessively when exposed to EMF radiation. Drinking a lot of water will ensure that your cells are working as efficiency and effectively as they can to help reduce the stress response EMF imparts on the cell. Keeping your body’s minerals, nutrient, and hormones balanced can also be an effective way to combat toxins like EMF. Meditation and other mindfulness techniques can help build the resiliency of your cells in your body.

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.

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).
