Very simply, we can say that electromagnetic waves (or electromagnetic fields - EMF) are invisible waves of energy that we also call radiation. These waves are created by the movement of electricity — in a circuit, an antenna, a light bulb — a bit like the swirls on the surface of a puddle when you throw a pebble into it. They have the capacity to transport information, but also energies.
Although not visible to the human eye, electromagnetic waves are present in our environment. It is important to know that there are 2 types:
Natural electromagnetic waves (OEM) which are emitted among others by the Earth, humans (our brain, our heart, etc.), animals, plants and stones. These waves do not cause any problems for the most part since they propagate without hitting or damaging our cells. Some are even essential to life. For example, the light sent to us by the sun is electromagnetic radiation identical to that of radio waves, but from a natural source.
Artificial electromagnetic waves (AEMA) which have been created by humans. They include radio waves, infrared rays, light rays, ultraviolet rays, X-rays, microwaves, smart meters, as well as all electronic devices such as cell phones, tablets, computers and wireless networks. These waves are unstable and move unpredictably, hitting our cells in their path, continually prompting our immune system to activate its defense mechanisms and thus creating constant stress in our body.
Animals and plants are also living beings sensitive to vibrations. They are also affected by electromagnetic waves, even more than us. OEMAs can therefore also have harmful effects on their health.
