Effect of massage on the nervous system. How bad habits affect the nervous system

The date: 22.09.2019

Some compare the role of the nervous system in the body with a computer, others with a conductor in a symphony orchestra. She leads the complex work of the body, all its organs and systems, regulating the processes occurring in it, realizing the connection of the body with the environment. Execution of any physical exercise occurs with the participation of the nervous system. It is thanks to this essential system that all movements human body, even the most complex ones, are consistent with each other.

In his works, the great physiologist Ivan Petrovich Pavlov studied the role of reflexes, that is, the body's response to external stimuli. He found that it was reflexes that help the body adapt to changes in the environment. Exercise and sports are some of the strongest irritants to the body. During physical exercises, a huge number of conditioned reflex connections are formed in the body between the muscles involved in the performance of movements, the internal organs that provide the muscles a sufficient amount of oxygen and nutrients, and the cerebral cortex. All types or divisions of the nervous system are involved in this process: central, peripheral and autonomic.

As a result of sports activities, the work and nutrition of the central nervous system improves. This is due to the activation of blood circulation, an increase in blood oxygen saturation. The brain receives nerve impulses from muscles and internal organs, their new combinations are formed, which causes the appearance of new reflexes. These new conditioned reflexes help to improve the functioning of the whole organism.

During sports training, the athlete gradually improves each new movement, bringing it to best performance... During each workout, new connections are formed in the central nervous system between nerve cells - neurons that control the work of the muscles that take part in the movements being worked out. At first, these movements are awkward, awkward, since new conditioned reflex connections have not yet had time to form, but with each new training they improve more and more, become more rational. When the connections are fully formed, the conditioned reflexes are fixed, the new movement is performed easily, naturally, almost automatically, without requiring special attention of the athlete.

Conditioned reflex connections formed during sports training affect not only muscle work. In addition to muscles, many other organs are involved in the performance of any movement, including the heart, blood vessels, and lungs. New connections coordinate the work of internal organs and muscles, as a result of which they work more actively, harmoniously, mutually influencing each other.

Regular physical exercise, sports training has a positive effect on all parts of the nervous system. As a result of training, the balancing of the processes of inhibition and excitation in the cerebral cortex is restored, its adaptability to new loads and changes in the environment increases.
Improving the functioning of the whole organism occurs only if different muscle groups are involved in the training process. And in the case when a person alternates different types activities, performs mental and physical work, regularly engages in sports training - he develops versatile and harmonious.

Diagnostic tests of the nervous system

It is possible to determine changes in the functioning of the nervous system using research methods that can be carried out with the use of special diagnostic equipment and without it. The simplest methods are Romberg's test, finger-nose test, Yarotsky's test. TO instrumental methods studies of the central nervous system include electroencephalography, rheoencephalography, electromyography, chronaximetry. With regular sports training, research results show the normal functioning of all parts of the central and peripheral nervous system, which confirms the positive effect of sports on its work.

Electromagnetic field(EMF) as physical concept is a special form of matter through which the interaction between any charged particles in motion is carried out. In other words, EMF occurs where electrical current is present. In this case, alternating current sources create a time-varying EMF, while direct current produces static EMF. The electromagnetic field is determined both by the electrostatic interactions that arise between charged particles, regardless of the mobility of the latter (the so-called electric field), and the magnetic component of the EMF, which determines the interactions between moving charges and, ultimately, between objects carrying an electric current (for example, repulsion or attraction of "electrified" objects). In this case, the strength of the electric field depends on the magnitude of the potential difference between the charged particles (i.e., on the voltage of the electric current) and on the distance between them and is expressed in volts per meter (V / m). In turn, the intensity magnetic field already depends on the strength of the current and also decreases with an increase in the distance between the sources of the latter, which can be expressed in amperes per meter (A / m). However, most often the strength of the magnetic field is expressed in units of magnetic induction - teslas or gauss (1 T = 10,000 G). In the special literature devoted to the problems of the biological action of EMF, the concept of "electromagnetic field" is interpreted more broadly. This term also denotes any electromagnetic radiation(EMP), the wavelength of which significantly exceeds the distance from the source to the target. The wavelength is directly related to the frequency characteristics of the electric current, as well as to the energy potential of EMP, the magnitude of which largely determines the direct effects of EMP (including on biological objects), which is well illustrated by the example of X-ray radiation.

All sources of EMF can be divided into natural and man-made. The former include the electric and magnetic fields of the Earth. Atmospheric discharges (thunderstorm activity) and radio emission from the Sun and galaxies are of much lesser importance. Unlike the earth's magnetic field, which is a static one, man-made EMFs are generated by alternating current sources and vary widely in their frequency characteristics. So, in accordance with international classification anthropogenic sources of EMF are divided into two groups:

[1 ] sources of EMR of extremely low and ultra-low frequencies (0 - 3 kHz), which, first of all, include all systems of production, transmission and distribution of electricity: overhead power lines (TL), transformer and generator substations, power plants, electrical wiring systems for residential and public buildings, various cable systems (including telephone, grounding systems, etc.), as well as any devices that use industrial frequency electricity for their work (50 - 60 Hz); the latter include the widest range of electrical and office equipment, professional electrical equipment, as well as electric transport and its infrastructure;

[2 ] sources of EMR of radio frequency and microwave ranges (3 kHz - 300 GHz), which include means of receiving and transmitting information (radio stations, radio and television transmitters, computer monitors, televisions, radio and cell phones, radar stations, etc.) , various medical treatment and diagnostic equipment, microwaves; Moreover, most of the listed devices are sources of EMP of ultrahigh frequencies (20 MHz - 3 GHz), i.e., microwave radiation.

For a living organism, it is not so much the magnitude of the effect of EMF that is of great importance, but the nature of the latter. This was experimentally established by W. Adey (1990), who showed that the exchange of calcium ions in brain cells in animals changes sharply only in certain very narrow frequency intervals EMF, while signals of other frequencies caused only minor changes or did not cause them at all. At the same time, attention was immediately drawn to the fact that most of the so-called. effective frequency windows were in the range of 0 - 100 Hz, and in many cases coincided with the own rhythms of the functioning of the brain and nervous system, heart and blood vessels, which made it possible to say that characteristic feature the impact of EMF on living organisms is its "resonant nature". That is, it is not the intensity of the EMP that is of significant importance, but rather the frequency characteristics, since in the case of coincidence of the latter with the natural vibrations of biomolecules of cell membranes, a multiple increase in the biological effect can occur. The data that the most aggressive effect on biological objects is exerted by irregular, i.e., dramatically changing in frequency, EMFs, which lead to desynchronization of their own electromagnetic signals in a living organism, fully correspond to the ideas about the information function of natural EMFs.

The extremely high biological activity of modulated EMFs can be considered in the same context. In this case, modulation, that is, the frequency of the EMF impulses, being synchronized with the own rhythms of the biological system, sharply increases the effectiveness of the EMF effect, and regardless of the main (carrier) frequency. Installed dependency biological effect EMFs from their frequency characteristics allow us to explain the fact that the alternating magnetic field of industrial frequencies (i.e. 50 - 60 Hz) has a pronounced effect on a person even at an intensity of only 0.2 - 0.4 μT, while the magnetic field The earth, measured in the range of 50 - 70 μT, does not have a negative effect on biological objects and belongs to natural environmental factors. This becomes clear when we take into account the fact that the latter, in terms of its frequency characteristics, refers to static, i.e. unchanging, magnetic fields, and, accordingly, has a completely different informational impact.

The main mechanism of the effect of EMF on a living object is a change in properties aqueous solutions organism. The main targets when exposed to EMF on biological objects are: plasma membranes cells, intra- and intercellular fluid. Electro-magnetic waves can increase the hydration of protein molecules.

Effect of EMF on the nervous system... The nervous system and the cardiovascular system closely interconnected with it are potentially the most vulnerable to exposure to EMF, because are bioelectric systems capable of responding to external influence electrical signals. It is the functional disorders of the nervous system of a different nature (headaches, fatigue, attention disorders, etc.), which are widespread among service personnel the first powerful radar stations implemented in the system air defense shortly after the Second World War, they first attracted the attention of doctors to the problem of the effects of EMF on humans. Thus, various aspects of the negative impact of EMF on functional state different departments the nervous system has been studied for about 50 years, and the possibility of the development of nervous pathology due to the influence of this factor has long been a generally accepted fact.

There are acute and chronic effects of EMF. At the same time, acute exposure involves a fairly short-term exposure to EMF of very high intensity (for example, during emergency repairs of power lines, accidents at power plants, etc.), which is accompanied by severe violations of autonomic regulation different functions, which develop as a result of reflex reactions, first of all, to the thermal effect of EMF. The latter is manifested by rapidly developing weakness, cardiac disorders, thirst, sometimes trembling in the limbs, spastic reactions vascular system, and in rare cases, vomiting. These changes are completely reversible with the timely termination of harmful effects.

Much greater importance has a pathology that develops as a result of chronic exposure to EMF, because affects very broad professional groups in the electrical industry. There are three main syndromes of disorders of nervous regulation: asthenic, asthenovegetative (or vegetative-vascular dystonia syndrome), hypothalamic.

Asthenic syndrome is mainly typical for initial stages diseases and implies the development of such functional disorders in working as frequent headaches, increased fatigue, irritability, various sleep disorders, recurrent pain in the heart of a functional nature, which, along with a tendency to arterial hypotension and bradycardia are a manifestation of disorders of the autonomic regulation of the cardiovascular system. In moderate stages of the disease, it develops asthenic-vegetative syndrome characterized by further aggravation of autonomic disorders. In this case, vagotonic reactions characteristic of the first phase of the disease are replaced by sympathicotonia, which predetermines the predominance of angiospastic reactions, the appearance of transient arterial hypertension, attacks of tachycardia and corresponds clinical picture hypertensive type of vegetative-vascular dystonia. In some severe cases, the disease develops hypothalamic syndrome, characterized by the periodic occurrence of diencephalic crises, predominantly of the sympatho-adrenal type. In such patients, emotional lability, hyperexcitability, instability of mood with a tendency to hypochondriac reactions, sleep disturbances and memory loss are observed. In severe cases, headaches become paroxysmal and are often accompanied by pre-syncope and fainting. Outside of crises, autonomic regulation disorders are manifested by symptoms such as excessive sweating, trembling fingers, low temperature skin and chilliness of hands and feet. In addition, patients complain of frequent squeezing and pinching pains in the region of the heart, which are difficult to act. vasodilators, sometimes sensations of interruptions in the work of the heart, periods of sudden lack of air, general weakness and fatigue. At additional examinations in such patients, an increase in blood pressure is often found, early development signs ischemic disease heart, cerebral blood flow disorders and changes bioelectric activity cerebral cortex, as well as borderline psychopathological changes. Such patients become disabled very early.

Experimental data show that there is a consciousness-independent receptor sensitivity to the effects of even very weak EMFs of the order of 0.0001 V / m, which is responsible for the development of various unconditional reflex reactions, which is manifested by changes in the autonomic (i.e., unconscious) regulation of various functions. which can underlie the development of many of the symptoms described above when exposed to EMF.

At the same time, other aspects of the influence of EMF (primarily of industrial frequencies) on the state of the human nervous system are widely discussed. At the same time, one of the most important problems of scientific interest since the beginning of the 1980s is the elucidation of a possible causal relationship between prolonged exposure to EMF and the prevalence of depressive states among workers and possibly suicides. The latter seems to be quite justified, since A much more frequent occurrence of such predisposing factors as emotional instability with a tendency to dysphoria, neurasthenia, hypochondriacal and phobic reactions among long-term workers in the electrical industry is already a generally recognized fact. In addition, as shown in a large number of studies carried out to date, there is an undeniable connection between the increase in the number of nervous and mental diseases and fluctuations in the Earth's magnetic field during the so-called periods. magnetic storms. To date, there are already a number of works that have shown a varying degree of risk of developing depressive symptomatology among workers in the electrical industry and the population living in the immediate vicinity of power lines. Several broad studies have found a link between occupational employment in the electrical industry and an increase in suicide rates in this group of workers. It is very alarming that these data were further confirmed with respect to the male population living in the immediate vicinity of the high-voltage transmission line (500 kV). At the same time, it should be borne in mind that due to the relative rarity of the studied pathology (suicide), the number of analyzed cases is often very limited, which seriously affects the reliability of the results obtained.

Another problem is the widespread occurrence both among workers employed in the electrical industry and among the population in a number of countries of a kind of psychosomatic disorders, defined as "hypersensitivity syndrome" and becoming widespread. The essence of this pathology lies in the fact that a number of persons in the process of working with various electrical equipment have paroxysmal headaches, severe weakness, attention disorder, as well as a number of unusual skin sensitivity disorders, such as numbness and paresthesias in the hands, a feeling of oily skin hands, hypersensitivity to the effects of various chemicals on the skin. At the same time, patients are often forced to consult a doctor, considering these symptoms to be a consequence of increased sensitivity to EMF and are often incapable of further work. In addition, there is a group of allergically susceptible people who may develop hypersensitivity to the effects of electric fields. Such patients may even lose consciousness during a thunderstorm or when passing under high-voltage power lines. However, numerous experimental studies that differ in terms of methodology have not shown a relationship between the occurrence of the described violations and the effect of EMF of varying intensity. Moreover, all patients included in the study were unable to distinguish between false and real exposure to EMF of industrial frequencies. Thus, to date, many researchers believe that the syndrome of "hypersensitivity" is a kind of psycho-somatic reaction to modern society fears and concerns that are associated with messages about a possible negative impact EMF, and which, in conditions of insufficient information, can be realized in somatic complaints. This assumption is supported, in particular, by the positive experience of psychological methods for correcting these disorders.

Since the mid-90s. the possibility of developing Alzheimer's disease in people by occupation associated with exposure to EMF (including industrial frequencies) is discussed. At the same time, in a number of studies it was shown that in the studied groups of patients with this disease it was almost 4 times more faces exposed in the past to industrial exposure to EMF than in the control groups. It is important to emphasize that the degree of risk did not change significantly when the group of subjects was expanded to more than 300 people, as well as after taking into account factors such as gender, education and age. At the same time, patients with other types of dementia (excluding vascular genesis). Currently, there are several assumptions that to some extent explain this dependence, including the possibility of a negative effect on the homeostasis of calcium ions in brain cells, pathological activation immune cells microglia (the cellular environment of neurons), leading to the degeneration of the latter, and, finally, a possible stimulating effect on the production of amyloid beta, which in large quantities found in brain cells in patients with Alzheimer's syndrome. Taking into account the proximity of some pathogenetic mechanisms, it was also suggested about the possible provoking effect of prolonged exposure to EMF on the development of lateral amyotrophic sclerosis, confirmed so far only in a single work.

Features of the human nervous system

The human nervous system (NS) is an extensive topic and requires a separate study. To have a figurative idea, consider some facts.

The nervous system ensures the interaction of all organs, creating a coordinated work of the organism as a whole and the formation of its reaction to internal processes and to information received from the outside world.

The NS has a certain anatomical structure, which includes:

central nervous system (CNS) - consists of the brain and spinal cord;
peripheral system (PS) - a network of nerve weaves that provide a connection between the central nervous system and the entire body.

The transfer of information takes place through neurons - nerve cells. Their structure resembles a spider: a body with legs. From the nucleus, there are short processes called dendrites, and long ones, axons.

Neurons interact with each other and transmit information in the form of an impulse to the central nervous system and back through the processes. Neurons are subdivided into: sensory and motor.

If you schematically represent the entire process of information exchange, then you get the following:

the receptor receives irritation and reorganizes it into a nerve impulse;
a sensitive neuron transmits an impulse further;
The central nervous system receives the signal and transmits the response back;
the motor neuron transmits the received impulse to the organ;
the organ shows a reaction.

Of course, the scheme looks much simpler than what is actually happening. In addition, the information transfer rate is very high.

As soon as we cut our finger, we immediately feel pain. This means that milliseconds pass from the moment of irritation to the final reaction.

Alcohol and the nervous system

Installed scientific fact: when alcohol is consumed, ethyl alcohol is absorbed in the intestines, after which it passes through the liver and reaches highest concentration in the brain. Under such conditions, a detrimental effect on the body is inevitable.

Back in the 19th century Scientific research terrible diagnoses were revealed in this area. THEM. Sechenov proved that ethyl alcohol partially paralyzes the central nervous system. I.P. Pavlov devoted his scientific work to how alcohol disrupts work and causes pathological changes in the structure of the brain and other organs.

S.S. Korsakov and V.M. Bekhterev, in addition to physical destruction, found the relationship of alcoholic beverages with the moral, intellectual and emotional sides of a person. Their work proved the degradation of personality in mental and moral terms. And as a result - an unstable mental state.

Taking just a few sips, a person already in a few minutes feels the first signs of intoxication. This means that ethanol has entered the cerebral cortex. Intoxication itself depends on the concentration of ethyl alcohol in the drink and the amount drunk.

It is worth noting: both fortified drinks and low-alcohol ones are equally harmful. Intoxication is divided into three stages: primary (from 0.5 to 1.4 in the blood), medium (from 1.5 to 2.4 in the blood), severe (from 2.5 and more ‰ in the blood).

The first stage of intoxication is characterized by relaxed movements, increased sociability, the presence of concentration, a slight decrease in reaction.

During the second stage, noticeable changes in human behavior appear: a wobbly gait, loud slurred speech, facial expressions are altered, mood can fluctuate and change dramatically. In such a state, a person cannot function normally. He thinks poorly, the reaction slows down significantly, self-control drops to low boundaries, and the world around him is perceived with difficulty.

The third stage of intoxication manifests itself with even more severe symptoms than the second. Due to the strongest intoxication of the body, a coma and death can occur.

Why do these changes occur under the influence of alcohol?

When ethanol enters the brain, it affects the interaction of the central nervous system and the peripheral. The response time during the exchange of information between organs and the brain is reduced. The neural connection weakens, and an impressive number of nerve cells die altogether.

Alcohol consumption often results in hangover syndrome... A person suffers from chills, nausea, in some cases vomiting and dizziness. Similar symptoms are manifested in toxic poisoning. It is not difficult to draw a conclusion: alcohol consumption is a voluntary intoxication of the body.

The consequences of regular alcohol intoxication

As mentioned earlier, the nervous system is an important conductor in the communication of organs and the brain. Drinking alcohol, even in small doses, causes colossal damage to health.

Intoxication and hangover are the primary effects of ethanol's effects on the brain and the rest of the periphery. The main destruction takes place inside at the cellular level and is cumulative.

Periodic exposure to alcohol nerve cells develops pathological changes that lead to impressive and even irreversible consequences in the brain. Decreased health indicators are common with alcoholism. Absolutely all vital functions of the body fall under the influence of intoxication: vision, hearing, blood supply, metabolic processes.

Like a strong poison, alcohol destroys cells. In addition to physical, mental pathologies are also observed.

People who drink alcohol over time suffer from nervous disorders, insomnia, depression. In severe cases, it develops delirium tremens... The person suffers from auditory and visual hallucinations, which can lead to self-harm.

In addition, mental activity and quality characteristics decrease. Asocial behavior in the family, at work, it is manifested by aggression, selfishness and indifference. The general degradation of a person proceeds gradually, but on an increasing scale.

Alcohol affects the human nervous system in a complex manner, reducing health indicators and personal qualities. Relief of fatigue and nervous tension with a glass of strong drink is expensive price, which will have to be paid in the near future.

Drinking alcohol has damaging effects on the nervous system. Often no one attaches these consequences of great importance... There are many articles in which scientific language with complex terms describes the effect of alcohol on the nervous system, which for the average person remains a mystery.

The work of the nervous system

Alcohol causes inhibition of the nervous system due to which the natural function of inhibition is inhibited.

Imagine strings - these are our nerve fibers. The nervous system is a receptor that must respond appropriately to any changes in the external world.

Let's imagine that some disturbance... The nervous system "catches" this disturbance with the help of nerve fibers, bending over. We perceive it and accept indignation as an appropriate decision.

Our nervous system is a detector of external disturbances and changes in the world.

This can be compared with some systems of human perception: the eye reacts to light, being an organ of light perception, the ear fixes the sound, the nervous system with the help of nerve fibers controls external disturbance.

Nerve fibers healthy person have sufficient elasticity. When a disturbance (some event) occurs, the nervous system reacts to it - the nerve fibers bend and the nervous system becomes excited. Other systems of the body's perception are also "on alert". When the disturbance passes, the nervous system returns to its original state (that is, the nerve fibers, due to elasticity, return to their original state and are ready to accept a new stimulus).

The more elastic the nerve fibers have, the more stress-resistant a person is considered.

The effect of alcohol on the nervous system

Alcohol depresses the nervous system. While drinking alcohol, you chemically affect the nervous system, forcing the "nerve fibers to relax" for no reason, and they become less sensitive. Alcohol seems to bring some kind of relaxation.

If you periodically consume alcohol, over time, the nervous system "unlearns" to relax on its own - to come from an excited state to its original state (the effect of inhibition). A person who constantly drinks alcohol loses the ability to relax. He teaches his body to relax only under the influence of alcohol.

Nerve fibers lose their elasticity

Let's take a look at how nerve fibers work.

Let's say there is some kind of external disturbance (change) in a person's life. The nervous system reacts to this and the nerve fibers "bend".

The outward change gradually fades away. BUT! The nervous system remains in an agitated state, as the nerve fibers have lost their elasticity.

If in a healthy person the nerve fibers have sufficient elasticity and quickly return to their original state (state of rest), then in a dependent person, the nerve fibers remain in an excited state for a long time.

How is it expressed:

A person experiences any stress for a long time.
Cannot calm down for a long time after stress.
Constant voltage builds up.

Other reactions are forming, I talked about them in the article.

The nerve fibers of a healthy person, in addition to having sufficient elasticity, have an even structure.

Imagine the nervous system as an area covered with nerve fibers. They are at the same distance from each other, creating a flat surface. If an external disturbance "falls" on this surface, the nerve fibers react clearly and reflect the impact.

The effect of alcohol on the structure of nerve fibers

Alcohol makes the reaction of the nervous system to external disturbance ambiguous.

Due to the deliberate suppression of nerve fibers, alcohol makes them react to external disturbance more pronounced. The structure of the arrangement of nerve fibers relative to each other changes. The fibers are displaced in different directions, due to which weak points are formed in the "response system". When external indignation occurs, falling into this " weakness", The nervous system cannot properly reflect this indignation and give the correct reaction, and as a result:

We are highly responsive to an external circumstance.
Our response becomes inadequate.
We can react too weakly or too strongly.

One way or another, the nervous system cannot give the correct reaction.

The structure of the nervous system of a person who has been drinking alcohol for a long time is an uneven and inelastic structure. The further use of alcohol only aggravates the situation, even more shakes the already weak nervous system.

This is how not only alcoholic addiction works, but also other addiction! Read about it in my article ““. In order not to inadvertently apply other dependent behavior.

Therefore, for a person who has been drinking alcohol for a long time, it is typical:

These and other signs carry in themselves an inadequate response to external indignation.

The nervous system, when drinking alcohol and after a period of abstinence, will be in an agitated state for a long time. This agitated state can be regarded as:

Anxiety.
Anxiety.
Something seems to be going wrong.

However, you need to realize that everything is really good in the outside world. And that due to the fact that the nerve fibers have lost their elasticity, they are still in a residual state of excitability. They will eventually come to rest, but this will take time.

The nervous system of a dependent person reacts differently to external circumstances than the nervous system of a healthy person.

At first, there is nothing left but to accept this feature the work of the nervous system as a fact, and adapt to such an interaction. Reducing stressful situations in your life as much as possible, avoiding excessive stress - this is what a person can do on his part.

This is the basis of the effects of alcohol on the nervous system.

To restore the functioning of the nervous system, complete abstinence from alcohol and all substances that alter consciousness and affect the "excitability" of the nervous system (including sedatives, various drugs, caffeine, nicotine, etc.).

It may take 2 to 4 years for the nervous system to fully recover, depending on the intensity of alcohol consumption.

Watch my video, in which I tell you how alcohol really affects the psyche

Leave your opinion in the comments, I will be grateful.

A large number of studies carried out in Russia, and the monographic generalizations made, give grounds to classify the nervous system as one of the most sensitive systems in the human body to the effects of EMF. At the level of a nerve cell, structural entities by transfer nerve impulses(synapse), at the level of isolated nerve structures, significant deviations occur when exposed to low-intensity EMF. Higher nervous activity and memory change in people who have contact with EMF. These individuals may have a tendency to develop stress reactions. Certain structures of the brain are hypersensitive to EMF. Changes in the permeability of the blood-brain barrier can lead to unexpected adverse effects. The nervous system of the embryo is especially sensitive to EMF.

Effects on the immune system

At present, enough data have been accumulated indicating the negative effect of EMF on the immunological reactivity of the organism. The results of research by Russian scientists give reason to believe that when exposed to EMF, the processes of immunogenesis are disrupted, more often in the direction of their oppression. It was also found that in animals irradiated with EMF, the nature of the infectious process changes - the course of the infectious process is aggravated. The emergence of autoimmunity is associated not so much with a change in the antigenic structure of tissues, but with a pathology of the immune system, as a result of which it reacts against normal tissue antigens. In accordance with this concept, the basis of all autoimmune conditions is primarily immunodeficiency in thymus-dependent cell population of lymphocytes. The effect of high-intensity EMF on the body's immune system is manifested in a depressing effect on the T-system of cellular immunity. EMFs can promote nonspecific suppression of immunogenesis, enhance the formation of antibodies to fetal tissues, and stimulate an autoimmune response in the body of a pregnant female.

Influence on the endocrine system and neurohumoral response.

In the works of Russian scientists back in the 60s, in the interpretation of the mechanism of functional disorders under the influence of EMF, the leading place was given to changes in the pituitary-adrenal system. Studies have shown that under the action of EMF, as a rule, there was stimulation of the pituitary-adrenaline system, which was accompanied by an increase in the content of adrenaline in the blood, activation of blood coagulation processes. It was recognized that one of the systems that early and naturally involves the body's response to the effects of various environmental factors is the hypothalamus-pituitary-adrenal cortex system. Research results have confirmed this position.

Influence on sexual function.

Sexual dysfunction is usually associated with a change in its regulation by the nervous and neuroendocrine systems. This is related to the results of work on the study of the state of the gonadotropic activity of the pituitary gland when exposed to EMF. Repeated exposure to EMF causes a decrease in the activity of the pituitary gland

Any environmental factor affecting the female body during pregnancy and affecting embryonic development is considered teratogenic. Many scientists attribute EMF to this group of factors.

Of primary importance in studies of teratogenesis is the stage of pregnancy, during which EMF is exposed. It is generally accepted that EMFs can, for example, cause deformities by acting at different stages of pregnancy. Although there are periods of maximum sensitivity to EMF. The most vulnerable periods are usually early stages development of the embryo, corresponding to the periods of implantation and early organogenesis.

An opinion was expressed about the possibility of a specific effect of EMF on the sexual function of women, on the embryo. A higher sensitivity to the effects of EMF of the ovaries than of the testes was noted. It has been established that the sensitivity of the embryo to EMF is significantly higher than the sensitivity of the maternal organism, and intrauterine damage to the fetus by EMF can occur at any stage of its development. The results of the conducted epidemiological studies allow us to conclude that the presence of women in contact with electromagnetic radiation can lead to premature birth, affect the development of the fetus and, finally, increase the risk of developing congenital malformations.

Other biomedical effects.

Since the beginning of the 60s, extensive research has been carried out in the USSR to study the health of people who have contact with EMF at work. The results of clinical studies have shown that prolonged contact with EMF in the microwave range can lead to the development of diseases, the clinical picture of which is determined, first of all, by changes in the functional state of the nervous and cardiovascular systems. It was proposed to isolate an independent disease - radio wave disease. This disease, according to the authors, can have three syndromes as the severity of the disease increases:

asthenic syndrome;

asthenic-vegetative syndrome;

hypothalamic syndrome.

The earliest clinical manifestations of the consequences of exposure to EM radiation on humans are functional disorders of the nervous system, manifested primarily in the form of autonomic dysfunctions of neurasthenic and asthenic syndrome. Persons who have been in the EM radiation zone for a long time complain of weakness, irritability, rapid fatigue, memory impairment, and sleep disturbance. Often, these symptoms are joined by disorders of autonomic functions. Disturbances from the cardiovascular system are manifested, as a rule, by neurocirculatory dystonia: lability of the pulse and blood pressure, a tendency to hypotension, pain in the heart region, etc. There are also phase changes in the composition of peripheral blood (lability of indicators) with the subsequent development of moderate leukopenia, neuropenia, erythrocytopenia ... Bone marrow changes are in the nature of a reactive compensatory tension of regeneration. Usually, these changes occur in people who, by the nature of their work, were constantly under the influence of EM radiation with a sufficiently high intensity. Those working with MP and EMF, as well as the population living in the area of EMF operation, complain of irritability and impatience. After 1-3 years, some have a feeling of inner tension, fussiness. Attention and memory are impaired. There are complaints about low sleep efficiency and fatigue. Given the important role of the cerebral cortex and hypothalamus in the implementation of human mental functions, it can be expected that prolonged repeated exposure to the maximum permissible EM radiation (especially in the decimeter wavelength range) may lead to mental disorders.
