Electromagnetic fields have existed as solar radiation and static fields since the formation of the Earth, and are essential for human life, since life itself is not viable without them. From the beginning of the 20th century, these natural electromagnetic fields have been joined by electromagnetic fields created artificially that have accompanied technological progress and improvements in the quality of life. Electrical networks and installations, as well as all types of machinery and domestic appliances that run on electricity, are also capable of generating electromagnetic fields.
This phenomenon, its applications in the field of medicine and its possible effects on health have been under study for the last five decades. Current scientific knowledge of the subject is very thorough and more ample than that of most of the chemical or food products that we consume or use on a daily basis.
