Electricity and health: how to protect yourself from electromagnetic radiation in everyday life
There is still a scientific debate about how our brain works, but researchers have already come to the conclusion that complex electrochemical processes between cells - neurons - are taking place inside us. For the exchange of information using short electrical pulses. They control all the muscles.
In this case, the person is constantly exposed Earth's natural magnetic field and electromagnetic waves. He has developed protective reactions in his body to such an effect, but they ... are not unlimited.
Risks and Hazards of Exposure
Over the past two centuries, people have begun to intensively use electricity and the benefits of civilization, not really worrying about their health. But in vain. The effect of electromagnetic radiation (EMR) on the body is constantly increasing, various diseases appear:
-
nervous depression;
-
weakened immunity;
-
problems with the reproductive system;
-
causeless fear;
-
crayfish.
Children are especially exposed to electromagnetic radiation: their fragile body is only formed for independent life, it must be protected in every way. And some adults from a young age attach a child to a mobile phone or other electronic devices.
To take this effect into account, the terms “Magnetic and electric field strength” are introduced. Consider them.

An electromagnetic field exists as a unique form of matter in which constant transformations of electrical and magnetic energies take place.
The stronger the power of electromagnetic sources, the greater the impact our body is exposed to. Sanitary standards determine that a voltage above 5 kV per meter is already hazardous to health. Such a space is observed under high-voltage equipment with overhead power transmission lines.
You can’t stay under them for long; housing is prohibited near them. Under such lines, the land is empty, and some agricultural enterprises are allowed to grow plants on it. But at the same time only mechanized processing is allowed without the use of labor of youth under 18 years of age.
However, in some areas under the power lines in the summer, local residents pick raspberries, lingonberries and other berries for several hours, even gardeners of summer residents are found.

People are exposed to electromagnetic effects while on the subway, traveling on commuter trains, trams, and trolleybuses. It is dangerous to be near broadcast television antennas, radio towers, masts of mobile operators.
Health Tips
Many do not even suspect how harmful the inept use of household appliances is. The level of safe field strength is known: only 0.2 μT.

The table below shows the average radiation levels from the surrounding devices and vehicles. They must be skillfully guided and understood that reducing contact time with hazardous factors reduces their effect on the body.
For example, not reaching one stop by tram, but walking this distance on foot after office work will benefit not only as a walk in the fresh air, but also reduce the impact of electromagnetic radiation.
When working with household appliances, you should increase the distance to it. Distance significantly reduces the risk of radiation. The diagram below shows how, under normal conditions, the tension decreases with distance from 3 to 30 cm.

Attention! Protection by distance and reduced time spent in a dangerous place are two main ways available to everyone.
In industry, they are supplemented by methods of shielding equipment and rooms with people by way of removing accumulated potentials to ground loops.
mobile connection
A professor of medicine from Japan, studying the effects of electromagnetic radiation on humans, was asked the question "Where is it safer to carry a cell phone in the body?" He replied: “keep it by the organ that you least need. If you have a strong heart, then wear a shirt or a jacket in the left breast pocket and heart problems will begin. You can also carry the phone on a trouser belt near the kidneys or liver - they will also function worse. ”
He was asked another question: are you talking on a cell phone? The professor replied: “Of course, like everyone else, but I carry the phone in my bag, not in my pockets. When driving, I use a special mount with a headset. ”
The Institute of Human Ecology recommends:
-
refuse games on the phone;
-
if necessary, the conversation is secluded from others so that they do not receive additional exposure;
-
use a headset and do not hold the phone near your head or increase the distance or turn on the speakerphone;
-
during a call, do not hold the mobile phone to your ear until the start of communication;
-
turn off the device at night, and do not keep it at the head of the head.

Electrical wiring and appliances
Some people believe that the outlet is safe when nothing is plugged into it. This is an erroneous opinion. The live wires of the apartment (even without load!) Are sources of radiation. Not de-energized, but hibernated TV, computer, microwave and other devices consume electricity, emitting electromagnetic radiation. Always turn off the power completely.
Reducing the electromagnetic effect from household appliances helps not only to increase the distance, but also the shielding of the housings performed by factories. A significant part of the signal from them is diverted through the contact of the PE conductor to the ground loop.

However, individual hosts use adapters that exclude such a connection, which can somehow be explained only by the absence of a PE conductor.
Laptops and computers
They work in every family. But not all users follow basic rules:
-
place the system unit at a distance, preferably under the table;
-
do not keep the laptop on your lap;
-
periodically take breaks to relax.
Final tips
Limit the number of working electrical appliances in the office and at home. In this way, electricity costs are saved, electromagnetic smog is reduced. No need to be afraid of electrical appliances: they make life easier. You just need to be careful, take care of yourself and your health, and when reducing electromagnetic radiation, do not forget to unload the body: move more time in the fresh air, engage in physical education, lead a healthy, active lifestyle.
