THE electromagnetic fields low frequency (220 Volts, 50-60 Hertz) are most undesirable for human health because these are the ones that interfere with the natural vibrations of the human body, for example with brain electrical transmissions. This makes sure that they can certainly be considered a stressor, if not a cause of disease.
Beyond the discussions on the dangers of electromagnetic fields, whose effects on health are not yet fully known, the propagation of electric and magnetic waves in homes should be limited if only for a matter of simple common sense by adopting precautions and countermeasures that are often quite simple.
The thing to keep in mind is that all electrical devices and installations (even the network itself) generate electromagnetic fields electric and magnetic type. This 'all' includes appliances, computers, TV and even the lamps of the bedside table lamp. Where electricity circulates there is a electromagnetic field.
Aware of this, the house should be divided into two areas from the point of view of electromagnetic fields: the sleeping area and the living room with as little electrical installations as possible and the other - kitchen, study, laundry room ... - where the devices are (inevitably) concentrated and where possibly the electricity meter is also located.
Then be careful not to confuse energy saving with low electromagnetic emissions. It may sound strange but energy saving bulbs generate electromagnetic fields stronger than incandescent ones and should be kept at a minimum distance of 1 meter. The distance of one meter should always be respected with all electrical appliances, including clock radios and baby phones that should never be kept on the bedside table or in the cot.
The sleeping and relaxation area of the house should be kept as clear as possible from electrical devices of any kind (how beautiful are the mechanical alarm clocks that make drin!) Including televisions, PCs and stereo systems. In this it should be noted that the stand-by function does not interrupt the electromagnetic fields. It is also very wrong to sleep with the mobile phone or tablet turned on next to the bed, but without forgetting that the recharging operation also generates electromagnetism.
To preserve an area of the house as free of electromagnetic fields it would also be good to avoid positioning the kitchen or bathroom appliances or the electric meter close to the wall that delimits the rest area or living room. As for the living room, it would be good to create a separate space to watch TV while in the bedrooms (starting with those of the children who are the most exposed) the absolute prohibition of the presence of electrical devices should apply.
Then of course there is the fundamental issue of design. The best defense from electromagnetic fields inside the house is a correct design of the electrical system, which should not only be implemented in accordance with current safety standards but also in such a way as to end the circuits and distribution lines as short as possible. The grounding of the individual elements of the electrical system is also important, including the metal elements of the thermo-hydraulic system such as radiators, pipes and more.
Speaking of the design and construction of electrical systems, it should be borne in mind that i electromagnetic fields they are smaller if the power lines have a straight, parallel or perpendicular course to the walls (therefore not diagonally). The lines should be concentrated according to a precise distribution design, the switches must have two poles and the cables must be shielded coaxial. If you entrust the work to an installer, make sure that it is up to date.
