Effect of electromagnetic radiation on telomerase. The impact of amy on human health. How to protect yourself from electromagnetic and radio frequency radiation

The interaction of external electromagnetic fields with the human body is carried out by directing internal fields and electric currents, the magnitude and distribution of which in the human body depends on the following basic parameters:

size, shape, anatomical structure of the body;

electrical and magnetic properties of tissues (electrical and magnetic conductivity and permeability);

characteristics of the electromagnetic field (frequency, intensity, etc.).

All this determines the complex nature of the effect of EMR on the human body, which is a specific volumetric-spatial composition of various organs and tissues from a dielectric and conductive material. This impact can be represented as follows.

The human body consists of many cells with a liquid content and intercellular fluid, which is an electrolyte. Cell membranes are good dielectrics and reliably isolate the intracellular phase. As a result, ion currents arise in a constant electric field, which flow only through the intercellular fluid.

In variable EMF, cell membranes lose their dielectric properties. With an increase in frequency, the intracellular environment is more and more involved in the total ionic conductance, which leads to an increase in energy absorption. At an EMF frequency of more than 10 6 ... 10 7 Hz, the ionic conductivity of the medium remains practically constant, and the absorption of energy continues to increase due to the vibration losses of the resulting dipole molecules of the medium (mainly water and proteins).

Thus, the absorption of EMP energy in tissues is due to the electrical resistance of the medium when conduction currents arise (loss of ionic conductivity) and due to friction (rotation) of dipole molecules in a viscous medium (dielectric losses). The thermal effect is a consequence of the absorption of EMP energy, i.e. heating of human tissues. The greater the field strength and exposure time, the stronger the indicated effect is.

The absorption and distribution of the absorbed energy inside the body also significantly depends on the shape, size and ratio of the body's dimensions to the radiation wavelength. From these positions, 3 areas can be distinguished in the EMP spectrum:

EMP with a frequency of up to 30 MHz;

EMP with a frequency from 30 MHz to 10 GHz;

EMP with a frequency of more than 10 GHz.

The first region is characterized by a rapid drop in the absorption value with decreasing frequency (approximately proportional to the square of the frequency). The second region is characterized by the presence of a number of absorption maxima, at which the body, as it were, draws in the field and absorbs more energy than is accounted for by its cross section. This leads to the formation of so-called "hot spots". For a person, the conditions for the occurrence of local absorption maxima in the head take place at frequencies of 750 ... 2500 MHz, and the maximum due to resonance with the overall size of the body lies in the frequency range 50 ... 300 MHz.

When the human body is exposed to EMR with a frequency of more than 10 GHz, almost all energy is absorbed in the surface layers of biostructures.

The energy of the field that has penetrated into the body is repeatedly reflected and refracted in the multilayer structure of the body with different thickness of tissue layers. As a result, the energy of the EMF is absorbed unequally, which explains the unequal effect on different tissues.

Thermal energy generated in human tissues increases the overall heat release of the body. Excess heat is removed to a certain limit by increasing the load on the thermoregulation mechanism. With an EMR intensity of more than 10 mW / cm 2, called the thermal threshold, the body cannot cope with the removal of the generated heat, and the body temperature rises.

The most sensitive to radiation are human organs and tissues that have poorly expressed thermoregulation (brain, eyes, kidneys, etc.). Overheating of tissues and organs leads to their diseases, and an increase in body temperature by 1 ° C and higher can lead to irreversible changes.

When exposed to high-frequency EMF, and especially microwave, on a living organism, there is also a non-thermal effect, which is the result of a number of microprocesses occurring under the influence of resonant effects of the interaction of external electromagnetic fields with the internal fields of the organism.

Exposure to EMR leads to various morphological and functional changes in the human body. With short-term exposure to low-intensity EMR, these changes are usually reversible, however, at high irradiation intensities or at systematic irradiation with low intensities, but exceeding the MPL, they are irreversible.

The negative effect of EMF on a person is expressed in the form of inhibition of reflexes, changes in the bioelectroactivity of the brain, memory impairment, the development of chronic depression syndrome, a decrease in blood pressure, a slowdown in heart contractions, changes in the blood composition towards an increase in leukocytes and a decrease in erythrocytes, disorders in the liver and spleen, clouding lens of the eye, hair loss, brittle nails. The immune and reproductive systems are also sensitive to EMF.

Recently, a number of works have been published on the possibility of developing autoimmunity under the influence of EMF, which is a serious pathology of the immune system. Autoimmunity is based on the fact that the body produces antibodies directed against its own tissues, cells and their constituent parts, which have a damaging effect.

There are also data on the relationship of EMR with cancer incidence, and this applies to both microwave and ultra-long ranges. For example, a higher incidence of cancer has been found among military personnel serving radars. It is believed that EMR is also one of the causes of leukemia in children.

Subjective criteria for the negative impact of EMF are headaches, increased fatigue, irritability, sleep disturbances, shortness of breath, blurred vision, increased body temperature.

Colleagues from the popular science project Kurzgesagt released an excellent video clip whether the electromagnetic radiation emitted by our phones, computers and household appliances is harmful. Zozhnik has translated this interesting data for you.

Electricity surrounds us everywhere: it makes our life more convenient, safer, more fun. And we don't even think about whether the electromagnetic waves studied by all the devices around us (for example, a smartphone) can harm our health. Can they slowly kill us?

First of all, let's remember what electricity is - it is a form of energy caused by the movement of a stream of charged electrons. This movement generates electrical and magnetic field , the action of which spreads in space. In principle, this phenomenon can be called “electromagnetic radiation” or radiation.

The word "radiation" (especially after the recent film "Chernobyl") makes people nervous. But radiation is generally ionizing radiation. As a heating radiator, it emits heat in the form of "infrared radiation" (although formally infrared radiation does not belong to radiation, but the principle is the same).

Most of the various radiation is harmless, but some types can, on the contrary, be very dangerous. For example, radiation (radiation) with very short waves, like in X-rays, gamma rays are so strong that they can knock electrons out of elementary particles, which can cause unpleasant consequences, for example, the destruction of body cells or genetic mutation.

This is what people usually imagine when they hear the word "radiation".

However, there is a huge spectrum of radiation with longer wavelengths ranging from visible light to infrared radiation, microwave radiation and radio waves. All these types of radiation are produced by technologies created by people: mobile phones, Wi-Fi routers, electrical wires, household electrical utensils.

This "radiation" does not destroy the molecules in our body.

Some types of radiation are useful for cooking dinner, for example, waves in the microwave cause the water molecules in food to move and this heats it up. This happens regularly with our bodies. For example, the pleasant warmth that we feel on our skin in the sun is electromagnetic infrared radiation from the sun that penetrates our body.

People and their ancestors from the beginning of time were constantly surrounded by natural and usually harmless electromagnetic radiation - from the sun, the Earth, from thunderclouds.

However, with the beginning of the industrial revolution, we have added many more sources of radiation to our lives. How harmless is it?

One of the first studies to gain public attention was conducted in 1979, when scientists found a link between higher levels of leukemia in those who live near power lines. However, this study was criticized because the connection between these phenomena could not be explained in any way.

However, the idea of ​​the dangers of electromagnetic radiation was entrenched and thousands of studies followed, the very fact of which suggests that the topic is very frightening to people.

By the way, many people claim to be sensitive to radiation from smartphones and electrical appliances. They complain of symptoms from radiation such as headache, nausea, skin reactions, burning eyes, or feeling tired.

Some studies have found much more alarming results: about the connection between the part of the brain to which the mobile phone is more often applied and the statistics of brain tumors.

The question that science is trying to answer is not so much whether there are dangerous consequences from radiation. Yes, X-ray exposure can damage cell DNA, and radio waves are harmless. The question is rather Are electromagnetic waves harmful in the long term for some reason not yet fully understood?

The question was not as easy as it seems. There are thousands of studies, articles, recommendations.

In addition, the media (and sometimes academics) often select data to support their own opinion, or to make the loudest statement possible.

For example, in a recent study last year (here is the official press release on its results, and here is the full text of the study), they looked for a connection between radiation from a smartphone and cancer in mice. The results were supposed to show the connection between these phenomena. But for some reason the connection was found only in male rats and is not found at all in mice and female rats. However, this study was presented as proving a link between smartphone use and cancer. However, there are both negative and positive findings in this study.

Today, the WHO officially classifies radio waves as “possibly carcinogenic”. In reality, such a wording means that it can potentially cause cancer, but so far it has not been proven and we will closely monitor this issue.

The WHO carcinogenicity classification includes 5 groups:

Group 1. Carcinogenic to humans... It has been scientifically proven that these substances and phenomena cause cancer. For example: plutonium, asbestos, smoking.

Group 2A. Possibly carcinogenic(Probably carcinogenic). This group includes now, for example: red meat, acrylamide.

Group 2B. Potentially carcinogenic(Possibly carcinogenic). In this group, WHO includes, for example, electromagnetic waves, chloroform, lead.

Group 3. Not classified as carcinogenic to humans.... For example, tea, coffee.

Group 4. Possibly not carcinogenic... For example, caprolactam.

When you look at this using all the data we have, there is no proven evidence yet that electromagnetic radiation can cause health problems in humans.

There are some statistical hints, but they do not hold up to scrutiny so far. Should you be afraid of radiation from laptops, smartphones, TV? Science so far gives the answer - no.

But what about people who say electromagnetic radiation is harmful to them? Scientists say that they are most likely experiencing the so-called nocebo effect ( more details: in the text about on Zozhnik).

If, for example, a person has a headache and after turning off the laptop it has passed, he can see the connection between these phenomena. And as soon as such suspicion crept in, the very idea that electromagnetic radiation can cause pain - and can be the true cause of pain. That is, not radiation, but the confidence that it should be so. This is the same as a placebo, just the opposite - it harms with the power of thought, and does not heal.

At least at the current stage of the development of science, we do not have convincing evidence that electricity (within the limits of safe use, of course) has any negative impact on people.

But in the attention economy: which we live in, things with unproven harm often overshadow the obvious, proven harm from other things. Just one example: Air pollution is associated with an estimated 4.2 million premature deaths a year.

Nevertheless, science does not stand still, and right now there is large-scale research on the impact of smartphones on human health. For example, the Cosmos study is a long-term study of the relationship between the volume and frequency of telephone calls and health problems.

But while we are waiting for the results of long-term research, if there are many other issues to focus on. For example, instead of worrying about how electromagnetic radiation can affect your health, it's better to worry about how these devices affect your health in a different way.

Bonus: a list of smartphones by the strength of electromagnetic radiation

The world around a modern person is filled with electromagnetic fields (EMF) of various origins. They are created both by natural objects and made by human hands.

The main natural sources of radiation are:

• own EMF of the Earth;
• solar radio emission;
• atmospheric phenomena associated with electricity.

Artificial sources of waves are:

• transformer substations;
• high-voltage power lines with voltage up to 1150 kV;
• power plants;
• household electrical appliances, for example: computers, laptops, electric kettles, televisions, washing machines, refrigerators, microwave ovens, hair dryers, electric ovens;
• hand-held power tools: screwdrivers, perforators, drills, electric saws, electric jigsaws and others;
• electrical wiring in a house or apartment;
• machine tool equipment powered by electricity;
• television towers and radiotelephone nodes;
• installations for radar;
• Wi-Fi equipment, such as towers;
• wireless communications: walkie-talkies, mobile phones;
• transmitting antennas;
• industrial equipment and installations powered by electricity;
• electric transport: trams, electric trains, trolleybuses.

How the electromagnetic field affects a person does not depend on the source, but is determined by its intensity, frequency, energy. In this case, the nature of the distribution of waves inside the premises is associated with the placement of objects and structures, the degree of their conductivity. Their frequency determines the penetrating properties.

Fields from the considered sources are static and variable. Their strength is determined by the power of the source. Each species has some characteristics associated with the nature of the impact on living organisms.

Impact of EMF on human health

The impact of electromagnetic fields on the human body is associated with the polarization of molecules (for example, water) that make up the human body. At the same time, they are guided by the EMF lines of force. As a result, the normal course of physical and chemical processes and the passage of nerve impulses are disrupted. Radiation of a variable nature also leads to heating of the tissues of the human body.

But the considered phenomena in the body arise only at a certain value of the field strength and some time after the beginning of their action. An important factor is also the individual sensitivity of each person, which makes it possible to endure the negative impact in different ways. Children with the elderly, persons with poor health are especially susceptible to changes in the electromagnetic background.

If the field strength norms (at a certain frequency) are exceeded, then the polarization mechanism primarily affects the organs containing the largest percentage of water. Overheating is dangerous to all living tissues. Therefore, the effect of EMF affects, to one degree or another, all systems of the body:

• nervous system usually reacts with the first appearance of migraines, fatigue, irritability, impaired memory, sleep, attention, coordination of movements, depression;
• immunity decreases, the number of leukocytes in the blood falls, while chronic diseases are exacerbated, the body becomes susceptible to respiratory infections;
• the value of blood pressure rises, which eventually leads to arrhythmias;
• the blood sugar level fluctuates, the work of the entire hematopoietic system is disrupted;
• the lens of the eye becomes cloudy;
• the functioning of the endocrine system worsens: there are failures in the production of the main hormones (adrenal glands, pituitary gland, thyroid gland);
• both men and women can become sterile;
• during pregnancy, the likelihood of miscarriage increases, as well as fetal malformations;
• the lens of the eye becomes cloudy;
• increased brittleness of nails is observed;
• DNA changes with prolonged exposure.

If the nervous system is severely affected, then delusional ideas, hallucinations appear, the adaptive capabilities of the personality fall. On an organic level, changes can lead to cancers such as brain cancer.

Due to total electrification, there has been an increase in negative impact fields of an electromagnetic nature on people. In medicine, a special term "radio wave sickness" has appeared. Experts believe that a third of the population of developed countries is already affected by the symptoms of this disease. But due to the commonality of symptoms with other diseases, the diagnosis of radio wave disease is difficult.

Existing radiation standards, their control

Electromagnetic fields and their influence on the human body are studied by a whole direction - electromagnetic safety. During the research, the maximum permissible radiation values ​​(in different frequency ranges) were established, the excess of which causes a deterioration in human health, indicating the need for protective measures.

All emissions are divided by frequency into the ranges shown in the table below. And also it contains the maximum permissible field strength values ​​that are not dangerous to humans.

Mobile communications, television and radio broadcasting operate in the ultrahigh frequency range.

On the territory of Russia, the maximum levels of EMF intensity are regulated by sanitary and hygienic norms and rules. Control functions are performed by representatives of the sanitary supervision, and at enterprises also by occupational safety specialists.

The maximum dose of electromagnetic radiation that a person can tolerate without harm to health is 0.2 μT according to the standards.

Reducing the negative impact of electromagnetic waves

The main protective measures that reduce to minimum level the effect of the electromagnetic field on the human body is:

• construction of houses outside the sanitary protection zones of high-voltage lines;
• passive, active or complex shielding of the emitting source;
• correct arrangement of furniture and electrical appliances in the room;
• the use of modern advanced equipment with a reduced level of radiated power;
• reduction of the time spent in the area of ​​the field;
• creation of a grounding system.

Either shielding the workplace is the safest method. In this case, screens are divided into absorbing and reflective. The latter type is made from metal sheets or mesh, which must be grounded.

Reducing cell phone communication will also help reduce exposure.

To accurately determine the electromagnetic background at home, it is enough to use a dosimeter. With its help, you can easily identify the most dangerous equipment in terms of radiation level in order to use it less. And also the device will allow you to arrange the devices in an optimal way so that the fields emanating from them are not amplified by mutual overlap.

Electricity brought comfort and entertainment into everyday life, made it possible to create coziness, made life easier. At the same time, the level of electromagnetic fields has increased to a dangerous level, which has a detrimental effect on the state of human health. The considered simple measures will help change the situation for the better. When purchasing household electrical appliances and tools, you should give preference to high quality products from well-known brands, while avoiding fakes.

The rapid development of science and technology in the XX century. led to the creation of generators of electromagnetic fields, which are widely used in industry, communications, the military, radio navigation, healthcare, and everyday life. Their widespread use is accompanied by progressive electromagnetic pollution. the environment that poses a threat to public health. Indeed, everyone knows about the dangers of watching television for many hours and continuous work at the computer during the working day.

Electromagnetic fields are biologically active - living things react to their action. However, a person does not have a special sense organ for detecting electromagnetic fields (with the exception of the optical range). The most sensitive to electromagnetic fields are the central nervous system, cardiovascular, and reproductive systems.

Long-term exposure to humans industrial frequency(50 Hz) leads to disorders that are subjectively expressed by complaints of headache in the temporal and occipital region, lethargy, sleep disturbance, memory loss, increased irritability, apathy, heart pain, heart rhythm disturbances. Functional disorders in the central nervous system, as well as changes in the composition of the blood, can be observed.

Impact electrostatic field on a person is associated with a weak current flowing through him. In this case, electrical injuries are never observed. However, as a result of a reflex reaction to the flowing current, mechanical injury from the ular about the nearby structural elements, falling from a height, etc. is possible. The central nervous system and the cardiovascular system are most sensitive to electrostatic fields. People working in the area of ​​electrostatic fields complain of irritability, headache, and sleep disturbance.

When exposed magnetic fields dysfunctions of the nervous, cardiovascular and respiratory systems, digestive tract, changes in the composition of the blood. With the local action of magnetic fields (primarily on the hands), there is a feeling of itching, pallor and cyanosis of the skin, swelling and compaction, and sometimes keratinization of the skin.

Impact radio frequency range is determined by the energy flux density, radiation frequency, exposure duration, irradiation mode (continuous, intermittent, pulsed), the size of the irradiated body surface, individual characteristics organism. Exposure to electromagnetic radiation can manifest itself in different form- from minor changes in some body systems to serious disorders in the body. Absorption of the energy of electromagnetic radiation by the human body causes a thermal effect. Starting from a certain limit, the human body does not cope with the removal of heat from individual organs, and their temperature can rise. In this regard, the impact of electromagnetic radiation is especially harmful to tissues and organs with insufficiently intensive blood circulation (eyes, brain, kidneys, stomach, gallbladder and urinary bladder). Irradiation of the eyes can lead to burns of the cornea, and exposure to EMR of the microwave range can lead to clouding of the lens - cataract.

With prolonged exposure to electromagnetic radiation of the radio frequency range, even of moderate intensity, disorders of the nervous system, metabolic processes, and changes in blood composition can occur. Hair loss and brittle nails may also occur. At an early stage, the disorders are reversible, but later there are irreversible changes in the state of health, a persistent decrease in working capacity and vitality.

Infrared (thermal) radiation being absorbed by tissues, causes a thermal effect. The most affected by infrared radiation are the skin and organs of vision. In case of acute damage to the skin, burns, a sharp expansion of the capillaries, and increased skin pigmentation are possible. With chronic irradiation, a persistent change in pigmentation appears, a red complexion, for example, in glass blowers, steelmakers. An increase in body temperature worsens health, reduces a person's working capacity.

Light emission also hazardous to skin and eyes at high energies. The pulsations of bright light impair vision, reduce working capacity, and affect the nervous system (for more details on light radiation, see Chapter 2, Section V).

Ultraviolet radiation (UVR) high levels can cause eye burns up to temporary or complete loss of vision, acute inflammation of the skin with redness, sometimes swelling and blistering, while fever, chills, and headache are possible. Acute eye lesions are called electrophthalmia. Chronic UVI of a moderate level causes a change in skin pigmentation (sunburn), causes chronic conjunctivitis, inflammation of the eyelids, and clouding of the lens. Long-term exposure to radiation leads to skin aging and the development of skin cancer. Low-level UVR is useful and even necessary for humans. But in a production environment, UVR is usually a harmful factor.

Impact laser radiation (LI) per person depends on the intensity of radiation (energy of the laser beam), wavelength (infrared, visible or ultraviolet range), the nature of their radiation (continuous or pulsed), exposure time. In fig. 1 shows the factors that determine the biological effect of laser radiation. Laser radiation acts selectively on various organs, emitting local and general damage to the body.

Rice. 1. Factors determining the biological effect of laser radiation

When irradiated, the eyes are easily damaged and the cornea and lens lose their transparency. Heating the lens leads to the formation of cataracts. The most dangerous for the eyes is the visible range of laser radiation, for which the optical system of the eye becomes transparent and the retina of the eye is affected. Damage to the retina can lead to temporary loss of vision, and at high energies of the laser beam, even destruction of the retina with loss of vision.

Laser radiation causes damage to the skin of various degrees - from redness to charring and the formation of deep skin defects, especially on pigmented areas (birthmarks, areas with a strong tan).

LI, especially in the infrared range, is capable of penetrating tissue to a considerable depth, striking internal organs... For example, direct irradiation of the surface of the abdominal wall causes damage to the liver, intestines and other organs; when the head is irradiated, intracranial hemorrhages are possible.

Long-term exposure to laser radiation of even low intensity can lead to various functional disorders of the nervous, cardiovascular systems, endocrine glands, blood pressure, increased fatigue, decreased performance.

Pathological changes caused by artificial electromagnetic fields in a living organism

The severity of the identified disorders is directly related to the intensity of the electromagnetic field, the duration of its exposure, the combination of certain levels of exposure and exposure time, the physical characteristics of various ranges of the electromagnetic field, environmental conditions, and the functional state of the body.

Most researchers who have studied the clinical picture of diseases that have arisen under the influence of electromagnetic fields agree that the nervous system reacts to electromagnetic waves earlier than others. Examination of a large number of patients made it possible to identify a symptom complex characteristic of the so-called magnetic, or radio wave illness. At the same time, the changes occurring in the body can be characterized as a functional disorder of the central nervous system, proceeding mainly as a type of autonomic dysfunction with asthenic phenomena, less often as a neurasthenic type.

Systematization of the clinical manifestations of the disease made it possible to distinguish three main forms: asthenic syndrome, vegetative-vascular (neurocirculatory) dystonia and diencephalic (microdiencephalic) syndrome.

At asthenic syndrome various disorders of autonomic functions, lability of the pulse and blood pressure are possible. The changes are usually reversible and treatable.

At the heart of vegetative-vascular dystonia lies vascular lability: fluctuations in heart rate and blood pressure, bradycardia, alternating with tachycardia, arterial hypotension, sometimes hypertension, changes in the function of the heart and capillaries. The disease can be protracted.

For diencephalic syndrome complex visceral dysfunctions, vegetative-vascular crises occurring against the background of an asthenic state are characteristic. Hypokinesia, hypothalamic-pituitary-adrenal weakness, inhibition of sexual and food reflexes are observed. Changes are not always reversible, such patients need specialized inpatient treatment.

According to the severity of the course of the disease, the following degrees are distinguished: first, or initial (compensated), second (moderately pronounced), third (pronounced). In some cases, the disease becomes chronic. Children especially suffer from radio wave sickness.

Every organ in our body vibrates, creating an electromagnetic field around itself. Any living organism on earth has such an invisible shell, which contributes to the harmonious work of the entire body system. It doesn't matter what it is called - biofield, aura - this phenomenon has to be reckoned with.

When our biofield is exposed to electromagnetic fields from artificial sources, this causes changes in it. Sometimes the body successfully copes with this influence, and sometimes not, resulting in a serious deterioration in well-being.

EMP (electromagnetic radiation) can be emitted by office equipment, Appliances, smartphones, phones, transport. Even a large crowd of people creates a certain charge in the atmosphere. It is impossible to completely isolate oneself from the electromagnetic background; it is present in one intensity or another literally in every corner of the planet Earth. It just doesn't always work.

The sources of EMR are:

• microwaves,
• devices with mobile communication,
• TVs,
• transport,
• sociopathogenic factors - large crowds,
• power lines,
• geopathogenic zones,
• solar storms,
• rocks,
• psychotropic weapon.

Scientists cannot determine in any way how harmful EMP is and what exactly constitutes the problem. Some argue that the danger is carried by the electromagnetic waves themselves. Others say that this phenomenon in itself is natural and does not pose a threat, but what information this radiation transmits to the body often turns out to be destructive for it.

In favor latest version give the results of experiments indicating that electromagnetic waves have an informational, or torsional, component. Some scientists from Europe, Russia and Ukraine argue that it is the torsion fields that, transmitting any negative information to the human body, harm it.

However, in order to check how strongly the information component destroys health and to what extent our body can resist it, it is necessary to carry out more than one experiment. One thing is clear - to deny the influence of electromagnetic radiation on the human body, at least, carelessly.

EMP norms for humans

Since the earth is full of sources of natural and artificial magnetic radiation, there is such a frequency that either has a good effect on health, or our body successfully copes with it.

Here are the healthy frequency ranges:

• 30-300 kHz, occurring at a field strength of 25 Volts per meter (V / m),
• 0.3-3 MHz, at a voltage of 15 V / m,
• 3-30 MHz - voltage 10 V / m,
• 30-300 MHz - voltage 3 V / m,
• 300 MHz-300 GHz - intensity 10 μW / cm 2.

Mobile phones, radio and television equipment work at these frequencies. The limit for high voltage lines is set at a frequency of 160 kV / m, but in real life they emit EMP radiation 5-6 times less than this indicator.

If the intensity of the EMR differs from the indicated values, such radiation can be harmful to health.

When EMR is harmful to health

Weak electromagnetic radiation with low power / intensity and high frequency is dangerous for a person because its intensity coincides with the frequency of his biofield. Because of this, a resonance is obtained and systems, organs begin to work incorrectly, which provokes the development of various diseases, especially in those parts of the body that have already been weakened by something.

Also, EMR has the ability to accumulate in the body, this is its greatest health hazard. Such accumulations gradually worsen the state of health, decrease:

• immunity,
• stress tolerance,
• sexual activity,
• endurance,
• working capacity.

The danger lies in the fact that these symptoms can be attributed to a large number of diseases. At the same time, doctors in our hospitals are in no hurry to take seriously the influence of electromagnetic radiation on the human body, therefore the probability of a correct diagnosis is very small.

The danger of EMR is invisible and difficult to measure, it is easier to look at bacteria under a microscope than to see the relationship between the radiation source and feeling unwell. Intense EMP has the most destructive effect on the circulatory, immune, reproductive systems, brain, eyes, and gastrointestinal tract. Also, a person may develop radio wave sickness. Let's talk about all this in more detail.

Radio wave sickness as a diagnosis

The effect of electromagnetic radiation on the human body was studied back in the 1960s. Then the pundits found that EMP provokes processes in the body that lead to failures in its most important systems. At the same time, the medical definition of "radio wave sickness" was introduced. Researchers claim that a third of the world's population has symptoms of this disease to one degree or another.

On initial stage the disease manifests itself as:

• dizziness
• headaches
• insomnia
• tiredness,
• deterioration in concentration,
• depressive conditions.

Agree, similar symptoms can be observed in a number of other diseases of a more "tangible" nature. And if a wrong diagnosis is made, then the radio wave illness makes itself felt with more serious manifestations, such as:

• cardiac arrhythmia,
• a drop or increase in blood sugar,
• persistent respiratory diseases.

This is the general picture. Now let's look at the effect of EMR on various body systems.

EMP and the nervous system

Scientists consider the nervous system to be one of the most vulnerable to EMP. The mechanism of its influence is simple - the electromagnetic field violates the permeability of the cell membrane for calcium ions, which has long been proven by scientists. Because of this, the nervous system malfunctions, functions in the wrong mode. Also, an alternating electromagnetic field (EMF) affects the state of the liquid components of nerve tissues. This produces deviations in the body such as:

• slowing down the reaction,
• changes in the EEG of the brain,
• memory impairment
• depression of varying severity.

EMR and the immune system

The effect of EMR on the immune system was studied by experimenting on animals. When individuals with various infections were irradiated with EMF, the course of their disease and its character were aggravated. Therefore, scientists have come to the theory that EMR disrupts the production of immune cells, up to the occurrence of autoimmunity.

EMR and the endocrine system

Researchers found that under the influence of EMR, the pituitary-adrenaline system was stimulated, which resulted in an increase in the level of adrenaline in the blood, an increase in the processes of its coagulation. This led to the involvement of another system - the hypothalamus-pituitary-adrenal cortex. The latter are responsible, in particular, for the production of cortisol, another stress hormone. Their incorrect work leads to the following consequences:

• increased excitability,
• irritability,
• sleep disturbances, insomnia,
• sudden mood swings
• strong jumps in blood pressure,
• dizziness, weakness.

EMR and the cardiovascular system

The state of health determines to some extent the quality of the blood circulating throughout the body. All elements of this liquid have their own electric potential, charge. Magnetic and electrical components are capable of provoking either destruction or adhesion of platelets, erythrocytes and block the permeability of cell membranes. Also, EMR affects the hematopoietic organs, disabling the entire system of formation of blood components.

The body reacts to such violations by throwing out an additional portion of adrenaline. However, this does not help, and the body continues to produce high doses of the stress hormone. This "behavior" leads to the following:

• the work of the heart muscle is disrupted,
• myocardial conductivity worsens,
• arrhythmia occurs,
• HELL jumps.

EMP and the reproductive system

It was revealed that the female genital organs - the ovaries - are more susceptible to the effects of EMR. However, men are not immune from this kind of influence. In general, this gives a decrease in sperm motility, their genetic weakness, therefore X chromosomes dominate, and more girls are born. It is also very likely that EMR will cause genetic pathologies leading to deformities and congenital malformations.

Influence of EMR on children and pregnant women

EMF affects the brains of children in a special way due to the fact that their body-to-head ratio is larger than that of an adult. This explains the higher conductivity of the medulla. Therefore, electromagnetic waves penetrate deeper into the child's brain. The older the baby becomes, the thicker the bones of his skull, the content of water and ions decreases, therefore, the conductivity also decreases.

The developing, growing tissues are subject to the greatest influence of EMR. A child under 16 is just actively growing, so the risk of pathologies from a strong magnetic effect in this period of a person's life is the highest.

For pregnant women, EMF poses a threat to both their fetus and their health. Therefore, it is desirable to minimize the effect of the electromagnetic field on the body, even in permissible "portions". For example, when a woman is pregnant, her entire body, including the fetus, undergoes minor EMR. How all this will affect later, whether it will accumulate and whether it will give consequences, no one can say for sure. But why test scientific theories on yourself? Isn't it easier to meet people in person and have long conversations than to talk incessantly on your mobile phone?

We add to this that the embryo is much more sensitive than the mother's organism to various kinds of influences. Therefore, EMF can make pathological "corrections" in its development at any stage.

The period of increased risk includes the early stages of fetal development, when stem cells "decide" what they will be in adulthood.

Is it possible to reduce the impact of EMR

The danger of the influence of the electromagnetic field on the human body is invisibility this process... Therefore, the negative effect can accumulate for a long time, and then it is also difficult to diagnose. However, there are some simple steps you can take to protect yourself and your family from the damaging effects of EMF.

Completely "turning off" electromagnetic radiation is not an option, and it will not work. But you can do the following:

• identify devices that create one or another EMF,
• purchase a special dosimeter,
• turn on electrical appliances in turn, and not all at once: a mobile phone, a computer, a microwave oven, a TV must work at different times,
• do not group electrical appliances in one place, distribute them so that they do not amplify each other's EMI,
• do not place these devices near the dining room, work table, resting places, sleeping,
• the children's room is subject to careful monitoring for sources of EMP, do not allow radio-controlled or electric toys, a tablet, a smartphone, a laptop,
• the outlet to which the computer is connected must be grounded,
• the base of the radiotelephone creates a stable magnetic field around itself within a radius of 10 meters, remove it from the bedroom and desktop.

It is difficult, and not necessary, to refuse the benefits of civilization. To avoid the harmful effects of EMP, it is enough to think carefully about what electrical appliances to surround yourself with and how to arrange them at home. The leaders in EMF intensity are microwave ovens, electric grills, devices with mobile communication - this just needs to be taken into account.

And finally, one more good advice - when purchasing household appliances, give preference to those with a steel case. The latter is able to screen the radiation emanating from the device, minimizing its effect on the body.
