Electromagnetic field

An electromagnetic field (also EMF or EM field) is a physical field produced by moving electrically charged objects.^[1] It affects the behavior of non-comoving charged objects at any distance of the field. The electromagnetic field extends indefinitely throughout space and describes the electromagnetic interaction. It is one of the four fundamental forces of nature (the others are gravitation, weak interaction and strong interaction).

The field can be viewed as the combination of an electric field and a magnetic field. The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell's equations and the Lorentz force law.^[2] The force created by the electric field is much stronger than the force created by the magnetic field.^[3]

From a classical perspective in the history of electromagnetism, the electromagnetic field can be regarded as a smooth, continuous field, propagated in a wavelike manner; whereas from the perspective of quantum field theory, the field is seen as quantized, being composed of individual particles.

Frequency is measured in cycles per second (hertz), wavelength is measured in meters, and energy is measured in electron volts. The strength of an EMF depends on its wavelength and frequency. More waves with shorter wavelengths create more energy as you move up the spectrum.

What Is the Range of Wavelength of Electromagnetic Waves?

At the low end of the electromagnetic spectrum are extremely low-frequency (ELF) waves. These have longer wavelengths and come from the 50- to 60-hertz power lines that feed household appliances. They can pose health risks, especially when they are close to the body for extended periods.

On the high end is radio frequency (RF) radiation. This comes from cell phones, cordless phones, mobile antennas, broadcast towers, electrical security systems and more. The higher the frequency, the greater the risk to health. For example, microwaves are very-high-frequency radiation, and they can pose a significant health risk. Many cell phone towers operate in the microwave range.

How Are Electromagnetic Waves Dangerous?

Bioelectrical signals help to regulate many processes of the human body. In fact, science suggests that every cell in your body might have its own EMF.

However, strong artificial EMFs can enter your body and interfere with the natural way your body works. This can affect virtually any system within your body, from your sleep cycles to your stress levels to your immunity to your DNA.

Dangers of Cell Phone Radiation

Whenever your cell phone is turned on, it is emitting potentially harmful EMFs. Possible side effects can range from disrupted sleep patterns to changes in DNA. Most people cannot function without their cell phone. But you can protect yourself against the danger.

EMF Danger from Cell Phones

When you hold your cell phone up to your ear, 10% to 80% of the radiation from the phone penetrates two inches into your brain. In children, the penetration is even deeper. Studies have shown that cell phones held near the head cause brain wave changes in 70% of people. The potential danger is so widely accepted that insurance companies are beginning to exclude coverage for injuries related to wireless phone radiation exposure.

These potential injuries can range from headaches and blurred vision to cancer:

Headaches
Genetic damage
Impaired immune system
Cancers, including brain tumors and melanoma
Break in the brain/blood barrier
Reduced melatonin
Interference with pacemakers
Memory loss
Changes in electrical activity in the brain
Cardiovascular stress
Fatigue
Eye problems

Wi-Fi Routers

Wi-Fi makes your life easier. You can get online from a coffee shop or from your living room. You are not tethered to a big computer that is physically linked to the Internet. But that convenience comes at a price.

Wi-Fi Dangers Made Worse by Cumulative Effect

Wireless routers – as well as Bluetooth and similar wireless systems – give off electromagnetic radiation in the low-gigahertz frequency. This level is considered potentially dangerous to people. And the danger is compounded by several factors:

Just like the wireless signals themselves, the EMFs can pass through walls.
Most routers are not turned off at night, so you are exposed 24/7.
You are not only exposed to EMFs from your own router. Did you ever search for a wireless signal and see not only your wireless network, but also your neighbor’s and the one from the business down the street? All of them emit EMFs.

Increasingly, scientists and researchers are uncovering the health risks of EMFs. Depending on the level and the length of exposure, those risks can range from insomnia and headaches to tumors. For more information on the health risks of EMFs from Wi-Fi.

Protecting Yourself and Your Family

You probably can’t get away from the effects of Wi-Fi. Even if you disconnect your own router – which probably would be very disruptive to your life – you are exposed to Wi-Fi at work, where you shop and in your neighborhood. You can protect yourself, though, with a range of effective and affordable products from SafeSpace.

Electrostress from Computers and Laptops

You probably are reading this on a computer. In fact, you probably spend hours every day in front of your computer. But that exposes you to potential health risks from EMFs emanating from both your computer itself and your monitor.

EMFs and Radiation from Your Computer

Your computer, whether it is a desktop or a laptop, emits EMFs. The closer you are to the computer, the stronger the electromagnetic field. Electromagnetic fields (EMFs) don’t only come from your computer screen. The electronics inside your computer generate a powerful EMF.

Close Proximity of EMFs

It’s been shown that EMF strength decreases with distance. Studies have shown that exposure above two milliGauss (mG) can begin to harm biological organisms. At a distance of three feet, you probably are above that level of exposure. If you are four inches or less away – such as when you are holding your laptop on your lap – your exposure might be as high as 20 mG. This level of exposure has been linked to many problems, from fatigue to immune suppression to cancer.

Computer radiation is at its fullest strength on the lap.

Laptop Radiation & Male Infertility

The use of laptops (especially when situated on the lap near the reproductive organs) has been connected to male infertility (Journal of Human Reproduction). Theories why include the heat from the machine itself on the scrotum, or radiation from the EMF at such a close distance.
