Are all EMFs (Electromagnetic Fields) harmful?

Interested in keeping your family healthy? If so, the chances are you’ve come across the term ‘EMFs’ (Electromagnetic fields), specifically in connection with mobile phones, wifi routers, laptops or smart meters. Due to their unfavorable impact on our wellbeing, the reputation EMFs have earned is very much a negative one. 

But are they all the same? Are they all harmful?

The answer is NO. They aren’t.  

Certain types of electromagnetic fields are naturally occurring and an integral part of life on Earth as we know it. And specific types of EMFs can be even used therapeutically, for example, to speed up the healing of broken bones.

 

In the following lines we will explain:

 

  • What are Electromagnetic Fields?
  • How do they occur in nature?
  • What is the problem with human-made mobile phone EMFs?
  • How to protect your family from harmful EMFs?

What are Electromagnetic Fields?

 

Essentially, we are all born into the sea of electromagnetic fields.  Similar to gravitational forces that keep our feet on the ground, EMFs are one of the fundamental forces of nature.

 

They are basically a combination of electric and magnetic fields and they come in different ‘shapes and sizes’.

 

From the picture below you can see that they differ in their wavelength (how far in between each wave) and frequency (how quickly the wave changes). Based on those characteristics we can organise them in a so-called Electromagnetic (EM) Spectrum. 

 

Ionising vs Non-Ionising Radiation

 

The EM spectrum includes both Ionising and Non-ionising radiation ranges. Ionising radiation is a type of electromagnetic field which carries enough energy to break down molecules (ionise atoms) and can be life-threatening. Examples include X-rays, gamma-rays and various types of radioactive materials. 

 

On the other hand, non-ionising radiation doesn’t carry enough energy to break molecular bonds. Power lines, microwaves, radio waves, infrared radiation, visible light, and lasers are all examples of this type of EMFs.

EMFs: a short explanation for the more technically minded

Eelectromagnetic fields are basically physical fields produced by electrically charged objects. They are able to influence the behaviour of other charged objects in their vicinity and can be viewed as the combination of an electric and magnetic field.  The electric field is produced by stationary charges (no flow), and the magnetic field by moving charges (currents). 

An electromagnetic field is defined by its frequency and wavelength. The field’s frequency and wavelength are directly related to each other: the higher the frequency, the shorter the wavelength.

Apart from some of the examples mentioned earlier, there are more sources of electric, magnetic and electromagnetic fields as we find them in nature. Many of them are not harmful to life:

 

  • We see electric fields produced by the local build-up of electric charges, such as s in the atmosphere associated with thunderstorms. 
  • Animals, such as birds or fish, use the Earth’s magnetic field for navigation. A compass needle does the same things when it moves in a North-South direction.
  • Your body creates its own electromagnetic field (we are all made of atoms!). It is the only way you can exist as one single entity.
  • Light and colours are part of the naturally occurring electromagnetic spectrum.
  • The UV light from the sun. 

 

Human-made sources of EMFs

The ability to listen to your favourite radio station, using a mobile phone, watching TV, being connected to the wifi or using an X-ray to diagnose a broken bone, these are all examples of human-made EMFs in action.

 

Even electricity that powers our house, for instance, is associated with EMFs at a very low frequency.

What’s the problem with human made EMFs emitted from mobile phones, towers or wifi routers?

Dr Devra Davis, the president of the Environmental Health Trust, explains that the impact of any form of EMFs depends on the nature of the waves they emit. 

 

For a moment, imagine listening to your favourite song. It has a regular beat to it, a melody and it makes you feel great. 

 

Now imagine that whilst you’re listening to it, someone is randomly increasing or decreasing the volume or muting the song on and off. Add a little bit of random interference, like when you’re driving in a car and the radio signal gets bad. Now that doesn’t feel that great, does it?

 

The nature of microwaves that phones, phone masts, wifi, and similar technologies emit is just like that.  It is pulsed, erratic and highly irregular.

 

Picture your cells ‘hearing’ and responding to this pulse for thousands of minutes per month, for many hours a week, over a lifetime. How does your body feel?

 

The truth is, our body doesn’t have the mechanisms to adapt to such blasts of an irregular signal. And it is also difficult to know what dose of this pulsed signal is your body getting at any point in time, depending on where you are.

 

According to Dr Beverly Rubik, a biophysicist and researcher, experiencing this again and again can have an accumulative effect, in some cases leading to electrosensitivity.  

 

And research already suggests some disturbing effects about these types of EMFs, including increased risk of infertility, neurological issues, increased inflammation or cancer. 

 

How to protect your family from harmful EMFs?

 

Doctors, surgeons and biomedical scientists of the Global Campaign for Safer Cell Phones recommend:

 

  1. Do not hold the phone directly against your head or body: Use speakerphone or another hands-free device.

 

  1. Use landline: Corded landlines are safer. Cordless phones emit microwave radiation.

 

  1. Beware of a weak signal: Your phone has to work harder and emit more radiation when the signal is weak or blocked.

 

  1. Protect children and the pregnant abdomen: Children absorb twice as much radiation as adults.

 

  1. Men who want to become fathers – beware: Sperm are especially vulnerable to radiation. 

 

  1. Do not text while moving: e.g. driving, biking, blading, walking, skiing. Milliseconds can make the difference between life or death.

 

  1. You can also opt-in for the use of shielding materials in your home, such as shielding curtains or wall paints or use a Qi-Home Cell (link to shop) to protect your home from EMFs.
