Electromagnetic fields in the home, how they affect us and how to mitigate them

In our homes, there are several sources of artificial electromagnetic fields (EMF) that we often overlook. From the TV in the living room to the smartwatch on our wrist and even the LED lamps on our desk, these can all contribute to the mysterious symptoms some people experience.

There is good news: there are different ways to minimize these risks.

Sources of electromagnetic fields (EMF) in the home

It is true that our body emits its own electromagnetic fields (EMF), but we are also vulnerable and susceptible to EMF coming from outside.

There are two common sources of EMF in the home:

1. Radio frequency (RF) radiation produced from wireless communications signaling.

2. Extremely low frequency (ELF) radiation produced by electricity.

Electromagnetic fields (EMF) from wireless electronics

Our everyday electronic devices emit radio waves for various reasons. Some examples include the mobile, Wi-Fi modems, Bluetooth devices, televisions and even smart watches and virtual assistants like Alexa. Even smart lighting and other “smart” electronics make this list.

Nowadays, technology has advanced a lot and more and more objects are becoming "smart." For this reason, it is less common to see people wearing traditional wristwatches.

Wireless and smart devices use radio frequency signals to connect to mobile networks and the Internet. These signals are invisible and are part of what is known as electromagnetic fields (EMF). Radio frequencies have a frequency that generally ranges between 3 kHz and 300 GHz.

Although radio frequencies offer convenience in daily life, various studies have revealed that they can also have harmful effects. For example, they have been shown to be linked to increased risk of brain and breast cancer, as well as impaired sperm health in human research.

It is important to keep in mind that not all radio frequencies have the same effect on our health.

In the past, analog radios and the first generation of mobile networks, known as 1G, used to transmit signals continuously. However, these days, most radio frequencies are digital, which can be more harmful.

While it has been claimed that the latest in technology 5G mobile network may have more limited coverage due to its higher frequency compared to 3G and 4G, Mr Finn noted that this claim may not be completely accurate. .

Leaves and rain can affect the propagation of certain 5G frequencies, but it is important to note that the 5G network operates in a wide range from 600 MHz to 39 GHz. These frequencies overlap with those used by 3G networks and 4G. Additionally, it has been observed that the lower subband frequencies (600 MHz to 1 GHz) can pass through brick and concrete walls without significant problems.

Ways to reduce radiofrequency exposure

– Go wired: Dr. David Carpenter, renowned professor of environmental health at the University at Albany, recommends using wired connections such as Ethernet cables and landline telephone lines for internet and telephone connections. This will help minimize reliance on wireless signals and reduce RF exposure, which can be beneficial in protecting our health.

– Replace Bluetooth headphones: To reduce exposure to radio frequency radiation, it is recommended to replace Bluetooth headphones with external speakers or use wired headphones. In this way, the distance between the phone and the head is maintained, thus reducing the potential effects of said radiation.

– Go “unsmart”: It is advisable to reduce the use of smart devices such as thermostats, blenders and smart watches.

– Take precautions at bedtime: Professor Emerita Magda Havas of Trent University explained to The Epoch Times that the time of going to sleep is crucial, since it is when our body rests and recovers from the stress accumulated during the day . During this period of rest, important healing processes occur in our body. Consider turning off Wi-Fi modems and putting cell phones and wireless devices on airplane mode before bed.

Electromagnetic fields (EMF) of electricity

Emitted by: overhead power lines, home wiring, stray currents and all electronic devices.

In addition to wireless devices, it is important to note that all home electronics emit extremely low frequency electromagnetic fields (EMFs), also known as ELF electromagnetic fields. Most household appliances operate at a frequency ranging between 60 and 300 Hz. It is relevant to consider these aspects to ensure a safe and healthy home environment.

Both radio frequency and ELF (Extremely Low Frequencies) have electrical and magnetic elements in their composition. However, it is important to note that only ELFs have been classified in electrical engineering standards that separately establish the magnetic and electric field components. Exposure to extremely low frequency (ELF) magnetic and electrical fields can have various effects on human health.

1. ELF magnetic fields

Electricity moves through wires similar to how water would in a flow. As it moves, it creates magnetic fields thanks to the current generated.

When examining an appliance, such as your hair dryer, it is important to pay attention to the plugs. These should have two metal pins that represent the two paired wires in the power cord: the "neutral" wire and the "hot" wire. In this case, the two wires are close to each other and conduct electric current in opposite directions. This specific configuration results in the cancellation of the magnetic field emission.

If the power cable has damage that causes the two wires to separate or if the neutral and hot wires are incorrectly connected, the magnetic fields will not cancel each other out. This may result in increased emissions of intensified magnetic fields.

It is important to note that electrical appliances with motors, such as refrigerators, dishwashers, and hair dryers, tend to emit strong magnetic fields. This is due to the generation of heat during operation. Therefore, it is advisable to take precautions and maintain adequate distance when using these devices to minimize exposure to these magnetic fields.

In 2002, the International Agency for Research on Cancer (IARC) classified ELF magnetic fields as "possible carcinogens" to humans. This classification highlights the need for further investigation and precautions regarding exposure to these magnetic fields.

2. ELF electric fields

When you plug a lamp into the outlet, an electric field is generated that extends from the plug to the power cord and then to the bulb. However, the magnetic field is only formed when you turn on the lamp.

Devices and appliances that are properly grounded with three-prong cords, where the third prong is a grounding conductor, will emit smaller electric fields compared to those that only have two prongs.

The resistance of the conduction rod to ground plays a key role in the flow of electricity. The lower this resistance is, the easier it is for electrical current to pass through it.

Currently, there is little research establishing a direct connection between low-frequency electric fields (ELF) and possible biological effects. However, it has been noted that some people sensitive to electromagnetic fields have reported symptoms related specifically to electric fields.

Various research has shown that exposure to ELF electric fields can influence sleep quality, according to animal studies. This suggests that these electromagnetic fields can have a significant impact on our rest and need to be considered as a factor to take into account to maintain good health.

Ways to reduce exposure to electromagnetic fields (EMF) and ELF electrical fields

– Inspect your electrical system: If you want to ensure the safety of your home, it is advisable to hire a qualified electrician to perform a wiring inspection. This review will allow you to verify if it is properly grounded and ensure that there are no errors or problems that could compromise the safety of your electrical installations.

– Avoid power lines: It is important to live and sleep away from power lines due to their ability to generate strong magnetic fields and ground currents. These can have adverse effects on our health and well-being.

– Use a Gauss meter: A Gauss meter is an instrument used to measure the intensity of magnetic fields. Its main function is to identify the areas in which the magnetic field has a greater intensity. This device is especially useful in various applications, such as scientific research, geological exploration, and electromagnetic engineering.

– Keep your distance: According to Mr. Finn, it is advisable to maintain a distance of 6 to 8 feet (1.80 to 2.40 m) from larger appliances and electronic devices, as well as electrical equipment while they are in use. This will help reduce your exposure to potential risks associated with these devices.

– Replace damaged appliances and use three-prong corded devices: It is recommended to replace electrical devices with two-prong cords with three-prong corded versions whenever possible.

– Turn off the electricity in the bedroom: In many cases, turning off the electricity in a room can decrease exposure to electromagnetic fields, which can be beneficial for those who are sensitive to them.

– Use voltmeters: Voltmeters are useful instruments commonly used to detect and measure electric fields.

3. Electromagnetic interference

Emitted by: wireless devices, fluorescent and LED lights, dimmer switches, solar panels, pool pumps, and air conditioning.

Electromagnetic interference (EMI), also known as signal-to-noise, line noise or dirty electricity, can be considered an unwanted phenomenon in terms of signal quality. It manifests itself through annoying sounds such as hissing in radios, humming in telephone conversations and flickering in television receivers.

The discrepancy between power lines and electronic devices arises because the former carry alternating current (AC) electricity, while most of the latter require direct current (DC) electricity. When converting from alternating current (AC) to direct current (DC) in household appliances, a side effect known as signal noise occurs.

Signal noise is not restricted to a particular area, but is dispersed throughout the house through the cables. In addition, it can also be broadcast on the air.

It is true that any device that uses diodes inevitably produces EMI (Electromagnetic Interference). Diodes are components commonly used in electronics to convert alternating current (AC) to direct current (DC).

LED lights have become one of the most used lighting sources today. These lights work through the use of diodes, which emit light when electric current is applied to them. The term "LED" is an acronym for "light-emitting diode."

The use of technologies such as Wi-Fi, smart meters and devices that emit radio signals can generate electromagnetic interference (EMI) due to interactions between different radio frequencies.

Fluorescent lights and variable speed motors used in pool pumps and air conditioning first convert AC electricity to DC and then back to AC electricity. When the electricity generated by solar panels goes through different conversions, Electromagnetic Interference (EMI) can be generated. However, dimmer switches do not generate signal noise through these conversions. Its function is to selectively cut alternating current waves that enter the lamp, thus avoiding the production of interference in the electrical output.

It has been reported that LED lights can affect sleep by influencing our circadian rhythm and reducing the production of melatonin, the hormone that regulates the sleep cycle.

Ways to reduce exposure to electromagnetic interference

– Ensure proper grounding: Without proper grounding, Electromagnetic Interference (EMI) can worsen. It is extremely important to ensure proper grounding to avoid any interference or damage to electronic equipment.

– Minimize certain electronic devices: One option to reduce signal noise produced by electronic devices, such as LED and fluorescent lights, is to consider replacing them with incandescent lights. Incandescent lights use a filament that is heated by electricity to produce light, making them more similar to natural light.

– Turn off devices: It is important to turn off electronic devices and appliances when you are not using them or when you go to sleep. This will allow you to save energy and reduce your electrical costs. In addition, you will contribute to the preservation of the environment by reducing your carbon footprint.
