Influence of electromagnetic waves on electronics. The effect of electromagnetic radiation on humans

Date: 11.10.2019

Technological progress also has a downside. The global use of various electrical technology has caused pollution, which has been given the name - electromagnetic noise. In this article, we will consider the nature of this phenomenon, the degree of its impact on the human body and protective measures.

What is it and radiation sources

Electromagnetic radiation is electromagnetic waves that occur when a magnetic or electric field is disturbed. Modern physics interprets this process within the framework of the theory of particle-wave dualism. That is, the minimum portion of electromagnetic radiation is a quantum, but at the same time it has frequency-wave properties that determine its main characteristics.

The frequency spectrum of the radiation of the electromagnetic field allows it to be classified into the following types:

radio frequency (these include radio waves);
thermal (infrared);
optical (that is, visible to the eye);
radiation in the ultraviolet spectrum and hard (ionized).

A detailed illustration of the spectral range (scale of electromagnetic radiation) can be seen in the figure below.

The nature of radiation sources

Depending on the origin, the sources of radiation of electromagnetic waves in world practice are usually classified into two types, namely:

disturbances of the electromagnetic field of artificial origin;
radiation emanating from natural sources.

Radiation emanating from the magnetic field field around the Earth, electrical processes in the atmosphere of our planet, nuclear fusion in the bowels of the sun - all of them are of natural origin.

As for artificial sources, they are a side effect caused by the operation of various electrical mechanisms and devices.

The radiation emanating from them can be low-level and high-level. The power levels of the sources completely determine the intensity of the electromagnetic field.

Examples of sources with a high level of EMR are:

Power transmission lines are usually high-voltage;
all types of electric transport, as well as the accompanying infrastructure;
tV and radio towers, as well as mobile and mobile communication stations;
installations for converting the voltage of the electrical network (in particular, waves emanating from a transformer or distribution substation);
elevators and other types of lifting equipment where an electromechanical power plant is used.

Typical sources that emit low-level radiation include the following electrical equipment:

almost all devices with a CRT display (for example: a payment terminal or a computer);
various types of household appliances, ranging from irons and ending with climate systems;
engineering systems that provide electricity to various objects (this means not only the power cable, but related equipment, such as sockets and electricity meters).

Separately, it is worth highlighting the special equipment used in medicine, which emits hard radiation (X-ray machines, MRI, etc.).

Impact on a person

In the course of numerous studies, radiobiologists have come to a disappointing conclusion that long-term radiation of electromagnetic waves can cause an "explosion" of diseases, that is, it causes the rapid development of pathological processes in the human body. Moreover, many of them introduce violations at the genetic level.

This is due to the fact that the electromagnetic field has a high level of biological activity, which is negatively reflected in living organisms. The influence factor depends on the following components:

the nature of the radiation produced;
how long and with what intensity it continues.

The impact on human health of radiation, which has an electromagnetic nature, directly depends on the location. It can be local or general. In the latter case, large-scale irradiation occurs, for example, radiation produced by power lines.

Accordingly, local exposure refers to exposure to specific areas of the body. Electromagnetic waves emanating from an electronic watch or mobile phone are a vivid example of local impact.

Separately, it is necessary to note the thermal effect of high-frequency electromagnetic radiation on living matter. The field energy is converted into thermal energy (due to the vibration of molecules), this effect is the basis for the work of industrial microwave emitters used to heat various substances. In contrast to the benefits in manufacturing processes, thermal effects on the human body can be harmful. From the point of view of radiobiology, it is not recommended to be near "warm" electrical equipment.

It must be taken into account that in everyday life we \u200b\u200bare regularly exposed to radiation, and this happens not only at work, but also at home or when moving around the city. Over time, the biological effect accumulates and intensifies. With the growth of electromagnetic noise, the number of characteristic diseases of the brain or nervous system increases. Note that radiobiology is a fairly young science, therefore, the harm caused to living organisms from electromagnetic radiation has not been thoroughly studied.

The figure shows the level of electromagnetic waves produced by conventional devices used in everyday life.

Note that the field strength level decreases significantly over distance. That is, in order to reduce its effect, it is enough to move away from the source at a certain distance.

The formula for calculating the norm (rationing) of the radiation of the electromagnetic field is indicated in the corresponding GOST and SanPiNah.

Radiation protection

In production, absorbing (protective) screens are actively used as means of protection against radiation. Unfortunately, it is not possible to protect yourself from the radiation of an electromagnetic field using such equipment at home, since it is not designed for this.

to reduce the effect of electromagnetic field radiation to practically zero, you should move away from power lines, radio and TV towers at a distance of at least 25 meters (the power of the source must be taken into account);
for a CRT monitor and TV, this distance is much less - about 30 cm;
the electronic watch should not be placed close to the pillow, the optimal distance for them is more than 5 cm;
for radios and cell phones, it is not recommended to bring them closer than 2.5 centimeters.

Note that many people know how dangerous it is to stand next to high-voltage power lines, but most people do not attach importance to ordinary household electrical appliances. Although it is enough to put the system unit on the floor or move it away, and you will protect yourself and your loved ones. We advise you to do this, and then measure the background from the computer using an electromagnetic field detector in order to visually verify that it is decreasing.

This advice also applies to the placement of the refrigerator, many put it near the kitchen table, practical but unsafe.

No table will be able to indicate the exact safe distance from a specific electrical equipment, since emissions can vary, both depending on the model of the device and the country of manufacture. At the moment, there is no single international standard, therefore, the norms may have significant differences in different countries.

You can accurately determine the radiation intensity using a special device - a fluxmeter. According to the standards adopted in Russia, the maximum allowable dose should not exceed 0.2 μT. We recommend taking measurements in the apartment using the above-mentioned device for measuring the degree of radiation of the electromagnetic field.

Fluxmeter - a device for measuring the degree of radiation of an electromagnetic field

Try to reduce the time when you are exposed to radiation, that is, do not stay for a long time near working electrical devices. For example, it is not at all necessary to constantly stand at the electric stove or microwave oven while cooking. With regard to electrical equipment, you may notice that warm does not always mean safe.

Always switch off unused electrical appliances. People often leave various devices turned on, without considering that at this time electromagnetic radiation emanates from electrical engineering. Turn off your laptop, printer or other equipment, it is unnecessary to be exposed to radiation unnecessarily, remember your safety.

Influence of electromagnetic radiation on humans

We live on a planet that constantly (24 hours, 7 days a week) has various kinds of effects on us. Electromagnetic radiation, whose influence on humans has increased in recent years, is one of the main factors that determine not only our life, but also our state of health. Let's consider how exactly the effect of electromagnetic radiation on a person occurs, and what consequences are caused by it.

Sources of electromagnetic radiation

On our planet, there is a natural background radiation (RFB) in the form of an endless stream of high-energy particles, in which there is living matter. PRFs are cosmic radiation (about 16%), gamma radiation from the Earth (almost 22%), radiation from living organisms (within 20%), as well as radiation from thoron and radon (42%).

PRP is ionizing radiation, the energy of the particles of which, when absorbed by a cell of the body, is capable of inducing decomposition or excitation of substances at the molecular level. Within 1 hour in living cells, an average of 200 million - 6 billion such transformations occur. It turns out that all organisms of the Earth at every second, starting from the moment of conception and ending with death, fall under the influence of electromagnetic radiation of natural origin.

Developing, people began to use electromagnetic energy for their own purposes. So, humanity has created an electromagnetic field (EMF) of artificial origin. But for a short period of its existence, it already significantly exceeds the level of the PRF. World energy resources double almost every 10 years, which also affects the growth of EMF.

The greatest influence of electromagnetic radiation on the health of humans and other animal organisms occurs in man-made radio frequency EMF and low-frequency fields. So, in the localization of substations and ultra-high voltage overhead lines, the intensity of the industrial magnetic field is higher than the natural level of the planet's magnetic fields by an average of 2-3 orders of magnitude.

With the development of artificial EMF due to the use of radio transmission means of communication (including mobile phones, televisions, radios, computers, etc.), the phenomenon of electromagnetic pollution, or "smog", arose. Non-ionizing electromagnetic radiation of low frequencies (up to 1000 Hz) is generated by electric vehicles, numerous transmission lines and cable routes. Some WHO experts believe that today the level of EM pollution of the planet is equal to its chemical pollution.

One of the strongest effects of electromagnetic radiation on a person in cities is provided by the centers of radio and television broadcasts, which emit around themselves ultra-short high-frequency waves. The strong influence of electromagnetic waves on the human body from household electrical appliances has long been noted. For comparison: when a person dries his hair with a hairdryer, the device influencing him generates magnetic induction in the range of 2000 μT, while the natural EM background of the Earth does not exceed 30-60 μT. Mobile phones, of which some people have several, emit decimeter waves of great penetrating power. Microwave ovens use microwave energy to cook and heat food.

Interaction of EMF with the human body

To date, in the course of a mass of research, the impact of electromagnetic fields on humans, which arose in an anthropogenic way, has been reliably established. Technogenic EMFs carry streams of different lengths and frequencies, unfavorable resonance phenomena, ultra-high-frequency radiation, from which the human body has not yet developed protection.

Regular exposure to an electromagnetic field of artificial origin can affect the performance of people, the ability to memorize, attention, and lead to many diseases of various organ systems. Anthropogenic magnetic background significantly increases the likelihood of developing cardiovascular and endocrine diseases, malignant tumors, immunodeficiency, erectile dysfunction in men.

But if the strong effect of electromagnetic fields on the human body has been sufficiently studied, then the influence of weak effects in many ways still remains a mystery. It is assumed that it is the weak effects that have an indirect effect in the form of carcinogenic and genetic effects.

Let's consider how electromagnetic fields of low and high frequency have an effect on the human body.

Effects of low frequency EMF on the human body

The impact of a low-frequency electromagnetic field on a person occurs in such a way that the latter plays the role of a conductor. Low-frequency EMF provokes a current in the body. Since electromagnetic waves in this case have a length many times greater than the size of a person, they have an effect on the entire body. Our tissues and organs have different structures from each other, that is, they have different electrical properties. Because of this, the impact on a person of low frequency EMF will differ in different parts of the body. The structures of the nervous system are most sensitive to low-frequency radiation.

The effect of electromagnetic radiation on the human body is manifested in a slight increase in the temperature of tissues in direct contact with low frequency waves. The effects of low-frequency wave radiation on an increase in the production of hormones of the pituitary and adrenal cortex were studied, which in most cases leads to the activation of elements of the reproductive system.

Researchers have established a definite connection between the development of oncological formations and the influence of the electromagnetic field on the human body, but these results require additional analyzes and repetitions. To date, the role of low-frequency EMF on the occurrence of leukemia and brain cancer in people of different ages who are regularly exposed to radiation has been accurately determined.

Ultra-low-frequency electromagnetic radiation is also hazardous to the human body. They can have the same effect on the human electromagnetic field as radiation.

How do high frequency EMF act on a person?

The body's response to high-frequency radiation (in contrast to low-frequency EMF) is manifested in the heating of tissues directly exposed to radiation. Moreover, the thermal reaction increases in proportion to the increase in the frequency of the EMF. Unlike low-frequency current, high-frequency current does not lead to excitation of nerve and muscle cells.

The influence of electromagnetic fields on a person can occur both locally (on certain parts of the body) and on the entire body. It depends on whether the effect of electromagnetic radiation on the human body occurs in whole or in part, and also on the wavelength.

The energy of microwave radiation is absorbed most of all by the aqueous media of the body. These waves hardly interact with the skin and adipose tissue, but have an effect on muscle fibers and internal organs. The effects of low-intensity microwave radiation on the central nervous system of humans are now being studied in detail. It was found that it has a cardiotropic effect on the body.

Special attention should be paid to the effect of microwave radiation on human health. The largest share of microwave pollution is assigned to radio stations and those objects that generate electromagnetic radiation in the microwave range. The workers of such stations systematically develop migraines, malaise, lethargy, problems with memorization, etc.

Depending on the nature of the irradiation and the magnitude of the dose, microwaves are usually divided into acute and chronic. Acute lesions are characterized by a thermogenic effect and short-term exposure to radiation. In chronic damage, microwaves act on the human body for a long time. The scary thing is that the influence of electromagnetic radiation on the human body in this case is manifested remotely, and therefore it is extremely difficult to identify its effects.

Numerous studies have established the high sensitivity of certain organs and tissues to the effects of EMF, namely:

central nervous system (overexcitation of nerve cells);
organs of vision;
gonads (men develop impotence, testosterone production decreases, and women may experience miscarriages, toxicosis during pregnancy, pathologies in the intrauterine development of the fetus);
organs of the cardiovascular system (myocardial dystrophy, coronary insufficiency, etc.);
endocrine glands;
immune system (with chronic radiation, leukopenia may develop).

The influence of the electromagnetic field on human health is manifested in three types of reactions on the part of the latter: excitement, heating and cooperation. Many scientific works are devoted to the first two, the third is still poorly studied.

You do not see him, but that does not mean that he is not here. Don't forget about the invisible killer. Avoid it where possible.

Electromagnetic fields (EMF)

Electromagnetic fields (EMF) are an anthropogenic and growing threat in the modern world. We need to know what it is, what the sources are and how it harms, in order to minimize negative health effects as much as possible.
If you are wondering why, while living a fairly healthy lifestyle, you still get sick often, you, it turns out, may be the victim of this silent killer.

There are two types of EMF - natural and man-made. We will be discussing here man-made EMFs, which pose a much greater threat to our health. They surround us, but we do not pay attention to the degree of damage that she can cause to our health and the health of our children. This is the dark side of technology and the price we have to pay for upgrades and amenities.

What is Electromagnetic Radiation (EMR)?

EMP is an invisible force that appears when an electrical current is passed through an electrical device. Electric and magnetic fields affect everything around them.

The intensity of the field changes with voltage. The higher the voltage, the stronger the electric fields. The interaction between electricity and magnetic fields produces electromagnetic radiation (EMP).

The effects of electric fields can sometimes be felt. For example, a tingling sensation may be felt. However, the magnetic field passes through most things unnoticed. This is energy that takes the form of waves, spreading outward from its source, very much like the ripples in water that occurs when a pebble falls into it. EMP travels through space at the speed of light, about 300 million meters per second, and it interacts with things in its path.

How EMFs Affect Our Health

We are in fact also electro-magnetic beings, micro-electric currents are generated by us and control the functions of our body, such as growth, metabolism, thoughts, movements, etc. Disruptions in the electrical network of our body can cause malfunctions in our internal organs, especially the brain.

Exposure to a consistent external frequency for several minutes can disrupt the electrical functionality of our body. This applies even to exposure to very weak EMFs.

Research has shown that prolonged exposure to EMFs can weaken the brain's defense mechanisms and cause psychiatric disorders such as depression, poor concentration, and insomnia. It also interferes with the body's natural healing process.

Our human bodies are very sensitive to EMF. When we interact with natural energies, we enhance the natural balance in our energy system. But when we are exposed to man-made EMFs, which are unnatural for our body, they create a chaotic situation that harms our health. Our bodies absorb and store energy fields that weaken our immune system, leaving us susceptible to various diseases.

Some diseases associated with constant exposure to EMF: headaches, chronic fatigue syndrome, memory loss, miscarriages, birth defects, leukemia, lymphoma, brain tumors, and even cancer.

Radio waves

Radio waves are energy emitted by radio stations. All wireless technologies have their own frequency bands, including remote controls, home alarm systems, cordless phones, cell phones, radios, remote control toys, global positioning systems (GPS), and more.

Radio waves can overheat our body's organs without affecting the skin. The thermal effects of these devices have been shown to be very harmful, resulting in: headaches, sleep disturbances, poor concentration, increased blood pressure, eye damage, especially with eye medications, childhood leukemia, the development of cancer cells in the brain, and much more. ...

Precautions for using cell phones:

Avoid using mobile or cordless phones for extended periods if possible.

If you really must use your phone, don't talk for long and use the speakerphone.

Use an external speaker that allows you to keep the phone away from your head.

If you wear glasses, go for plastic frames and non-metallic accessories. The conductor material can serve as an antenna and send radio waves directly to your brain.

Television Waves - Extreme Low Frequency (ELF) waves

The TV emits EMF in all directions while it is turned on, not just when it is turned on. Larger screens can emit a stronger field that can even penetrate walls. Other devices that emit ELF: computers, laser printers, copiers, electric blankets, electric clocks.

Some of the health risks from prolonged exposure to a computer are: miscarriages, low birth weight in newborns, vision and hearing problems, suppressed immunity, hyperactivity in young children, skin irritation, etc.
.
Precautions for using TVs and displays:

Move at least 24 inches away from the screen.

EMF spreads from all sides of the computer, especially from the top and back. Move at least three feet away from the computer you are using.

Avoid working on your computer for more than two hours a day.

Turn off the power of your TV or computer when not in use.

Wear safety glasses, if possible, to reduce exposure to ultraviolet radiation, which can cause cataracts.

Place some live plants next to your computer. Leaves can absorb infrared radiation.

Power plants

Power lines are very high voltage and emit electric and magnetic fields. How far is your home from power lines? The safe distance is about 1000 meters.

Substations can be located close to home and they emit very strong magnetic fields. The further your home is from any power plant or transformer, the better.

Scientific studies have found a link between increased cancer incidence and proximity to power lines. In another study, epidemiologist Dr. Nancy Wertheimer of the University of Colorado showed that children living near power lines were three times more likely to develop leukemia and cancer. Children are more susceptible to the effects of EMF.

Many other studies have confirmed their findings and found an increased risk of leukemia, lymphoma, brain tumors, brain and nervous system cancers. There is also evidence of a link between EMFs and phenomena such as sudden infant death, fatigue, headaches, central nervous system disorders and wasting.

Dangers from the medical field

Diagnostic X-rays expose you to unnecessary radiation. Professor and director of medical physics in London wrote: "Medical exposure today makes the largest man-made contribution to the radiation load of the population of developed countries."

X-rays

X-rays of ionizing radiation cause irreparable damage to our body. There is no such thing as a "safe" X-ray. X-rays have more energy than light waves and can travel through the body. The radiation energy can damage cells in the body, which increases the risk of cancer. Even if the risk is quite low, it grows with the number of X-rays you receive over the course of your life.

CT (computed tomography) is a moving beam of X-rays that creates a three-dimensional image (for example, of the brain). And therefore, the dose of radiation received is much higher than that of a standard X-ray. Young children undergoing such an examination are at much greater risk.

Mammography

Ionizing radiation in mammography puts the body at great risk. The dose of radiation received is 1000 times greater than with a chest x-ray. The breast tissue is extremely susceptible to radiation. So you can see that mammography can trigger the development of breast cancer that women want to avoid with their yearly mammogram! Avoid this at all costs.

Dangers in the house

Most household electrical appliances also emit EMF, but this is much less dangerous.

Here are some of them:

Fluorescent lamp. Emits EMP of visible and ultraviolet light. Prolonged exposure to a fluorescent lamp has been found to cause red blood cells to clump, reduce alertness, and feel tired. Always choose natural sunlight if possible.

An electric watch also emits electrical energy. Do not place them near your bed if possible.

Electric blankets create EMFs that can penetrate 6-7 inches into the body. Research has linked electric blankets to miscarriages and childhood leukemia.

Other electrical appliances that emit low levels of EMF: hair dryer, shaver, vacuum cleaner, microwave oven, washing machine, dishwasher, refrigerator, etc.

Precautions you can take at home:

Grow indoor plants. Plants are natural, eco-friendly air purifiers and their leaves can absorb infrared radiation.

Use electrical appliances for short periods. Turn off the power when not in use.

Move all electrical appliances at least 6 meters away from the bed.

Don't put your cell phone under the pillow as an alarm clock. It emits EMF even when not in use.

Limit the time your children spend watching TV and computers.

Minimize the use of electrical devices such as radios and microwaves. Turn off the power when not in use.

What is it and radiation sources

The frequency spectrum of the radiation of the electromagnetic field allows it to be classified into the following types:

radio frequency (these include radio waves);

Fluxmeter - a device for measuring the degree of radiation of an electromagnetic field

Electromagnetic radiation (EMR) accompanies a modern person everywhere. Any technique whose action is based on electricity emits waves of energy. Some types of such radiation are constantly being talked about - these are radiation, ultraviolet and, the danger of which has long been known to everyone. But people try not to think about the effect of electromagnetic fields on the human body, if it occurs due to a working TV or smartphone.

Types of electromagnetic radiation

Before describing the danger of a particular type of radiation, you need to figure out what it is all about. School physics course tells that energy travels in the form of waves. A large number of types of radiation are distinguished depending on their frequency and length. So electromagnetic waves include:

High frequency radiation. It includes X-rays and gamma rays. They are also known as ionizing radiation.
Mid-frequency radiation. This is the visible spectrum that humans perceive as light. The upper and lower frequency scales are ultraviolet and infrared radiation.
Low frequency radiation. This includes radio and microwaves.

To explain the influence of electromagnetic radiation on the human body, all these types are subdivided into 2 large categories - ionizing and non-ionizing radiation. The difference between them is quite simple:

Ionizing radiation affects the atomic structure of a substance. Because of this, the structure of cells in biological organisms is disturbed, DNA is altered and tumors appear.
Non-ionizing radiation has long been considered harmless. But recent research by scientists shows that with high power and prolonged exposure, it is no less dangerous to health.

Sources of EMR

Non-ionizing electromagnetic fields and radiation surround a person everywhere. Any electronic equipment emits them. In addition, we must not forget about the power lines through which the most powerful charges of electricity pass. EMP is also emitted by transformers, elevators and other technical devices that provide comfortable living conditions.

Thus, it is enough to turn on the TV or talk on the phone for the sources of electromagnetic radiation to begin to affect the body. Even such a seemingly safe thing as an electronic alarm clock can affect health over time.

EMP measuring devices

To determine how strongly a particular source of EMP affects the body, devices are used to measure electromagnetic fields. The simplest and most widely known is the indicator screwdriver. The LED at its end burns brighter with a powerful radiation source.

There are also professional devices - fluxmeters. Such a detector of electromagnetic radiation is able to determine the power of the source and give out its numerical characteristics. They can then be written to a computer and processed using various examples of measured values \u200b\u200band frequencies.

For a person, according to the standards of the Russian Federation, an EMR dose of 0.2 μT is considered safe.

More accurate and detailed tables are presented in GOST and SanPiNah. In them, you can find formulas, thanks to which you can calculate how dangerous an EMP source is and how to measure electromagnetic radiation, depending on the location of the equipment and the size of the room.

If radiation is measured in R / h (the amount of roentgen per hour), then EMP is in V / m 2 (volts per square meter). The following indicators are considered safe for a person, depending on the frequency of the wave, measured in hertz:

up to 300 kHz - 25 V / m 2;
3 MHz - 15 V / m 2;
30 MHz - 10 V / m 2;
300 MHz - 3 V / m 2;
Above 0.3 GHz - 10 μV / cm 2.

It is thanks to the measurements of these indicators that the safety for a person of one or another source of EMP is determined.

How does electromagnetic radiation affect humans?

Considering that many people have been in constant contact with electrical devices since childhood, a natural question arises: is EMP so dangerous? Unlike radiation, it does not lead to radiation sickness and its effect is imperceptible. And is it worth observing the norms of electromagnetic radiation?

Scientists also asked this question back in the 60s of the 20th century. More than 50 years of research have shown that the human electromagnetic field is modified by other radiation. This leads to the development of the so-called "radio wave illness".

Spurious electromagnetic radiation and interference disrupt the work of many organ systems. But the most sensitive to their effects are nervous and cardiovascular.

According to statistics in recent years, about a third of the population is affected by radio wave sickness. It manifests itself through symptoms familiar to many:

depression;
chronic fatigue;
insomnia;
headaches;
concentration disorders;
dizziness.

At the same time, the negative impact of electromagnetic radiation on human health is most dangerous because doctors still cannot diagnose it. After examination and testing, the patient goes home with a diagnosis: "Healthy!" At the same time, if nothing is done, the disease will develop and pass into a chronic stage.

Each organ system will respond differently to electromagnetic stimulation. The central nervous system is most sensitive to the effects of electromagnetic fields on humans.

EMP impairs signal transmission through the neurons of the brain. As a result, it affects the activity of the organism as a whole.

Also, over time, negative consequences for the psyche appear - attention and memory are disturbed, and in the worst cases, problems are transformed into delusions, hallucinations and suicidal tendencies.

The influence of electromagnetic waves on living organisms has a large-scale effect through the circulatory system.

Erythrocytes, platelets and other little bodies have their own potentials. Under the influence of electromagnetic radiation on a person, they can stick together. As a result, vascular blockage occurs and the performance of the transport function of blood worsens.

EMR also reduces the permeability of cell membranes. As a result, all tissues exposed to radiation do not receive the necessary oxygen and nutrients. In addition, the effectiveness of hematopoietic functions decreases. The heart, in turn, reacts to this problem with arrhythmia and a drop in myocardial conduction.

The influence of electromagnetic waves on the human body destroys the immune system. Due to the clumping of blood cells, lymphocytes and leukocytes become blocked. Accordingly, the infection simply does not meet the resistance of the defense systems. As a result, not only the frequency of colds increases, but also the exacerbation of chronic ailments occurs.

Another consequence of the harm from electromagnetic radiation is the disruption of hormone production. The effect on the brain and circulatory system stimulates the work of the pituitary gland, adrenal glands and other glands.

The reproductive system is also sensitive to electromagnetic radiation, the effect on a person can be catastrophic. Considering the violation of hormone production, male potency decreases. But for women, the consequences are more serious - during the first trimester of pregnancy, a strong dose of radiation can lead to a miscarriage. And if this does not happen, then the disturbance of the electromagnetic field can disrupt the normal process of cell division, damaging the DNA. The result is developmental pathologies in children.

The effect of electromagnetic fields on the human body is destructive, which is confirmed by numerous studies.

Considering that modern medicine can practically do nothing to oppose radio wave illness, it is necessary to try to protect yourself on your own.

EMI protection

Taking into account all the possible harm that the influence of the electromagnetic field brings on living organisms, simple and reliable safety rules have been developed. In enterprises in which a person is constantly faced with high levels of EMR, special protective screens and equipment are provided for workers.

But at home, sources of an electromagnetic field cannot be shielded in this way. It will at least be inconvenient. Therefore, you should understand how to protect yourself in other ways. In total, there are 3 rules that must be observed constantly in order to reduce the effect of the electromagnetic field on human health:

Stay as far away from sources of EMP as possible. For power lines, 25 meters is enough. And the screen of a monitor or TV is dangerous if it is located closer than 30 cm away. It is enough to carry smartphones and tablets not in pockets, but in purses or purses 3 cm from the body.
Reduce the time of contact with EMP. This means that you do not have to stand for a long time near the working sources of the electromagnetic field. Even if you want to follow the cooking on the electric stove or warm up by the heater.
Switch off unused electrical appliances. This will not only reduce the level of electromagnetic radiation, but it will also help save money on your electricity bills.

You can also take a set of preventive measures to minimize the impact of electromagnetic waves. For example, having measured the radiation power of various devices with a dosimeter, it is necessary to record the EMF readings. Then the emitters can be distributed around the room to reduce the load on individual areas of the area. It is also important to take into account that the steel case shields EMI well.

Do not forget that electromagnetic radiation of the radio frequency range from communications equipment constantly affects human fields while these devices are turned on. Therefore, it is better to put them away before going to bed and during work.
