Does a computer irradiate a person? Electromagnetic radiation from a computer: methods of protection

Twitter

We all know that the space around us is filled with all kinds of energy fields and electromagnetic radiation coming from all household appliances(TV, radio, refrigerator and others).

IN Lately joined this range of sources of electromagnetic radiation computer .

On the one hand, this is a unique device, without which many people cannot imagine their life and work; it is an inexhaustible source of knowledge. Everyone now knows the word "Internet".

On the other hand, The computer is the source of many diseases. The phrases “chronic fatigue syndrome” and “information stress” are also familiar to many. And that is not all.

Risk of exposure to radiation electromagnetic field on the human body has long been a scientifically proven fact. A number of diseases are associated with the influence of electromagnetic fields on the human body.

The nervous, immune, endocrine and circulatory systems are primarily affected. This is expressed in increased fatigue, headaches, sleep disorders, allergies, anemia, and reproductive dysfunction.

I think it would be appropriate to say that the Chinese called the radiation coming from the computer “dragon teeth”. Since the source of electromagnetic fields is electricity, high-current wires create powerful magnetic fields - invisible lines of force that easily penetrate everything that comes in their way, including penetrating the human body.

Scientists have found that the greatest radiation from computer is coming in front and to the right of the user. This radiation exceeds acceptable standards. In the 1980s, scientists discovered that low-intensity electromagnetic fields negatively affect the ability of T lymphocytes to destroy tumor cells. This means that such fields suppress the immune system and thereby contribute to the formation of tissue tumors and blood diseases.

I will address your Special attention that when exposed to weak electromagnetic fields generated by the display, tissue responses may follow repeated pulses of the field. As a result, the rhythmicity of vibrations of tissue elements will repeat the temporal periodicity of the field - this phenomenon is called “increase”. As a result, cellular immunity and the activity of various enzymes may change, similar to what happens when tumor growth is stimulated.

Scientists have found that people who work on computers are much more likely to have children with birth defects. Measuring the radiation emanating from the monitor, we found that it was as close as possible to sawtooth. This has an extremely negative effect on the embryo, especially in the early stages of development. In this case, the nervous system of the unborn child suffers the most.

It has been observed that women who work on computers have a relatively higher incidence of miscarriages. Doctors noted that people who work at a computer for more than 2 years experience disturbances in the functioning of the tail of the pancreas, this very important organ of the endocrine system.

But the radiation from the processor, which goes in all directions, is the cause of skin and allergic diseases. The situation is aggravated by the fact that human senses do not perceive electromagnetic fields. A person does not feel this type of radiation and cannot control its level of presence himself. A person knows that there is radiation, but he does not know its intensity. This condition can be defined as “situational stress”.

Simple and magical methods to protect people working on a computer

In order to reduce the level of harmful radiation emanating from the monitor and processor, without resorting to expensive filters and circuits, sometimes it is enough to simply change the location of the computer in the room. To do this, you need to position the computer in relation to the person sitting behind it, from the south or southwest side. Since the field lines of background electromagnetic radiation come from the north pole and end at the south. The computer's background radiation will be contained by natural background radiation coming from the north. As a result, an invisible barrier will arise that protects the person.

The room in which the computer is located must have live plants. It’s especially good if they are pink or red pelargoniums, and plants from the family begonias. Very good plant - pike tail. Flowers must be looked after, they must be watered regularly, and, what is very important, dust must be wiped off them.

But in the immediate vicinity of the computer, on the monitor or to the right of the processor, it is advisable to “settle” cactus. This unique plant will greatly help you protect your health.

It is very good if the room in which you work has a computer aquarium with fish. An aquarium is a must round shape. It should contain odd number of fish. Among these fish there must be at least one gold, red and black fish. It is advisable that the aquarium with fish be in your field of vision when you are working.

It has a great protective effect against harmful computer radiation. red clay. From red clay you must mold with your own hands three balls, each with a diameter of approximately 3 cm. One ball should be placed between the monitor and the keyboard. And the other two should “rest” at this time, preferably on the windowsill so that they get sunlight, and sometimes fresh air.

Every ball should be near the monitor for one week, and cleaned for two weeks. That is, once a week the ball near the monitor is replaced with one of the two located near the window. Once every six months, the clay balls must be completely replaced. Used clay balls are best left in the field.

It also has protective properties rosin. You need to take a piece of rosin, preferably in the shape of a cube with sides measuring at least one and a half cm or a parallelepiped measuring 2 x 4 x 1 cm and place this piece of rosin in front of the monitor. Rosin should be in front of the monitor at all times. It needs to be changed after a year.

We should not forget about such a simple remedy as lime. Lime should be poured into a matchbox the size of a match and placed in open form behind the monitor, at a distance of five centimeters from the back wall of the monitor. Lime must be changed once every three months.

Basically, those who sit for days in an embrace with the old huge “monitor” depicted here should be afraid. And almost no one has these anymore. But let's also give more important tips , which, despite their simplicity, can really save your health and vision.
And then we’ll touch on the topic of radiation, which is not so scary with modern screens.

So, first and most importantly, don’t be afraid of radiation, but take care of your eyesight:

1. When working with a screen, take BREAKS for 10-15 minutes every hour, relax, look into the distance. LED bulbs directly into the eyes, no one has yet helped save their eyesight.

2. Do EYE EXERCISES (rotate your eyes, etc.).

– Watch the LIGHTING: electric light should not be too bright, but also do not create a “cinema” for yourself, working at the monitor in a dark room. AND THERE SHOULD BE NO GLARE on the screen.

3. Install on your computer free program Flux https://justgetflux.com
This program makes working with the monitor much easier for the eyes. Before installing Flux, my eyes got very tired after just 10 minutes of sitting in front of the monitor. And so I installed this application. I even forgot about the previous pain in my eyes; I don’t experience them anymore. The program makes the image on the monitor warmer (in color temperature), and it becomes more suitable for vision. Others who use it write the same thing.

4. MOVE! Sitting motionless in front of a screen for long periods of time harms you worse than any radiation. It is fraught with fatigue, hemorrhoids, osteochondrosis, diabetes and other “charms”.

This problem can be solved by taking regular breaks. Do simple exercises, go outside more often, breathe fresh air. When working for a long time, change your body position, stand up, and walk around. IN free time walk more, play sports.

NOW ABOUT RADIATION ACTUALLY

1. Regarding "X-ray" radiation from monitors, then you don’t have to worry about it too much.
For “ancient” cathode ray tube (CRT) monitors it is within normal limits, but for liquid crystal monitors it is not at all.
2. But to electromagnetic field should be taken more seriously.

Electromagnetic field namely electron beam monitor (see picture) is quite large and therefore harmful to health. This is especially true for pregnant women. Some experts believe that electromagnetic fields can have a harmful effect on the embryo, starting from the moment of conception and during the first months of pregnancy.

From such a monitor, the field extends to the sides and especially back from it at a distance of up to 1-1.5 m. (Therefore, according to the rules, no one should sit BACK of a cathode-ray monitor).

The vast majority of you have had a LCD monitor for a long time, and although it also creates an electromagnetic field, it is not as intense and harmful as that of cathode-ray screens. Therefore, in terms of safety liquid crystal preferable.

What to do if you have to work specifically on an electron beam a monitor like the one shown in the picture?

First of all, Monique is preferable, compliant with TCO-95, TCO-99 standards or later. Such monitors have built-in protection against electromagnetic radiation (built-in protective screen, special foil inside the case), and therefore they are almost safe. However, for this protection to work, the CRT box must be CORRECTLY grounded. Therefore, if you want to protect yourself from electromagnetic fields, call an electrician to properly ground your monitor. Grounding MUST NOT be made to the working “zero” of the power supply system, battery or water pipe!

The computer is one of the most remarkable achievements of human intelligence. The possibility of direct dialogue between users through a computer and the enormous resources of a PC has led to the fact that millions of people are spending more and more time in front of its screen. Over time, computer users develop a set of specific health complaints.

This makes us think about the impact of computer radiation on human health. There are many reasons for such thoughts. A number of scientists associate health problems with people’s exposure to electromagnetic radiation from household microwave sources.

What is the harm of computer radiation?

We are the first generation of people to live in an ocean of enormous amounts of visible and invisible radiation. Therefore, there are still no reliable statistics summing up all the research of scientists on this topic. So what do the pundits say?

Every PC is a source of low-frequency and radio-frequency radiation. Health experts say:

both types of rays are carcinogenic;
they increase the risk of cardiovascular diseases and hormonal disorders;
as well as Alzheimer's disease, asthma and depression.

All parts of the computer can be harmful. The processor generates this same microwave radiation, which “happily” spreads in space in the form of electromagnetic waves, often carrying misinformation to the human electromagnetic field.

To determine in which direction from the monitor harmful radiation is maximum, you should remember that its front part has protective covering. But the back wall and side surfaces are not protected. Manufacturers computer equipment The primary task was considered to ensure the safety of the operator sitting in front of the screen, so the opinion that radiation from the monitor from the back and sides is stronger is quite justified.

Cathode ray tube monitors, thank God, are becoming rarities of history. The damage they caused was very significant. The LCD monitors that replaced them are certainly safer, but they still emit radiation. By the way, the word radiation, indicated in the computer documentation, is translated as radiation, but not as radioactivity.

Due to heating motherboard and the housing, air is deionized and harmful substances are released into the environment. This is why the air in rooms with constantly running computer technology, very difficult to breathe. For people with a weak respiratory system, this factor can have a detrimental effect, triggering asthma. It is further aggravated by the influence of the electrostatic field of the computer and monitor on dust particles suspended in the air. Once electrified, they form a “dust cocktail” that makes breathing difficult.

Availability touch screen does not guarantee you the absence of radiation at all. After all, when performing manipulations on the screen, your fingers are constantly in contact with it, and a few millimeters from the Wi-Fi antenna.

Particularly worth discussing is the problem of radiation from laptops, which were designed as portable devices for working on the road. Using these convenient and multifunctional devices for a full working day may well cause all sorts of pathologies and diseases. After all, it, like an ordinary computer, is a source of electromagnetic radiation, and is also located in close proximity to a person. Many users even carelessly place it on their knees, in close proximity to vital organs.

Computer radiation and pregnancy

Pregnancy is an extremely important time in a woman’s life. From the moment of conception until the birth of the child, the growing fetus is extremely sensitive to adverse external influences. Therefore, intrauterine damage to the embryo by an electromagnetic field can occur at any stage of its development. Particularly dangerous in this regard early dates pregnancy, when miscarriages most often occur and malformations of the unborn baby develop. Therefore, the expectant mother should treat the issue of the influence of computer radiation on pregnancy very responsibly.

Despite the compactness of a laptop, radiation from it during pregnancy is no less dangerous than the same exposure from regular computer- the intensity is the same, plus the influence of the Wi-Fi transmitter. In addition, many women, even during pregnancy, do not give up the habit of keeping it portable device on your lap, that is, in close proximity to the developing baby.

Ways to protect yourself from the harmful effects of a computer

The flip side of technological progress is the dangers associated with it. How to avoid them or at least minimize them? How to reduce radiation from a computer? Information about its harmful effects should logically be accompanied by recommendations on methods of protection from its radiation.

Do plants help protect against computer radiation?

Even among respectable office workers, there is an opinion that some plants protect against computer radiation.

So which flower protects against computer radiation? Cactus is traditionally preferred here. This myth is even summed up " scientific base": the role of antennas is attributed to the plant needles, formulas are given and calculations are made. If there was a grain of truth in this statement, then in the homeland of cacti - Mexico there should be problems with the operation of radars, but there are none.

The reality is that neither a cactus nor any other plant will protect you from computer radiation!

A flower near the computer can lift your spirits, decorate a strict work atmosphere, and become a positive emotional component in everyday work. And an “emotional placebo” can neutralize the harmful effects of electromagnetic radiation.

Concluding all of the above, we conclude that protection from microwave radiation of a computer begins from the moment you select this companion for your family in the store. And it ends with a reasonable approach to its operation and measured time spent in front of the invitingly flickering screen.

The computer is a major breakthrough in the field modern technologies. The ability to communicate via the Internet has become the reason for people to conduct large quantity time in front of the monitor. In this regard, the influence of the computer on the health and human body is of great importance. After all, many users complain about their health. Scientists attribute this to the influence of electromagnetic radiation on people.

Computer damage

Why is a computer harmful? First of all, it harms the eyes. Small vibrations and flicker from the screen can strain the eye muscles, which reduces visual acuity over time.

Working at a computer causes dry eye syndrome for many, which brings a lot of inconvenience and discomfort. Prolonged eye strain can provoke a spasm of accommodation. This is false myopia, it can be eliminated with the help of hardware treatment or certain exercises.

The computer is also harmful to the spine. Constantly being in one position puts stress on only one muscle group. This can provoke their degradation and damage to the intervertebral discs, which leads to osteochondrosis, the appearance of a hernia, headaches, and pain in the internal organs. Children often experience spinal curvature.

The most important negative factor is electromagnetic radiation emanating from the computer. Modern technology has become much safer than older models, but not entirely harmless.

The computer also negatively affects the genitourinary system. Prolonged sitting creates a thermal effect between the chair and the user's body, which leads to stagnation of blood in the pelvic area. The result of this is hemorrhoids, and there is also a risk of prostatitis.

The computer is harmful to the human psyche. It is especially dangerous for the health of children, because popular shooting games often cause great damage to their mental state. Many people are also addicted to the Internet.

Working at a computer reduces the user's physical activity, which disrupts the body's metabolism, causing excess weight and cellulite.

Pregnancy

Is a computer harmful during pregnancy? This is a very important period in a woman’s life. During this period, the child is extremely sensitive to negative external influences. Intrauterine damage to the fetus by electromagnetic radiation is possible at any stage.

Especially expectant mothers need to be careful in the first trimester. At this time, miscarriages occur more often and various malformations of the child appear. Therefore, pregnant women should not forget about the dangers of a computer.

Radiation from a laptop is just as harmful as that from a regular computer. You should not place a laptop on your lap, especially during pregnancy, because in this case it will be very close to the fetus.

What effect do computers have on a person during pregnancy when they spend a long time looking at the monitor?

A prolonged sitting position disrupts metabolism and blood circulation in the pelvic area, which leads to blood stagnation. This negatively affects the uterus, disrupts blood flow to the baby, and can also lead to hemorrhoids.
During pregnancy, due to the severity of the fetus, huge pressure on the spine. By aggravating this with a prolonged sitting position, you can get osteochondrosis, as well as some joint diseases.
Harmful effects computer on vision while carrying a child is also dangerous, especially for those who already have problems in this area. Pregnancy and childbirth can cause rapid progression of the disease.
This technique is also harmful to the mental state of the pregnant woman. Computer radiation can cause irritation, depression, and fatigue.

Impact on children

What harm or benefit does a computer bring to children? Currently, children's knowledge of the world is simplified using modern technology. The computer helps develop memory, thinking, and creative skills. Games develop motor coordination, children learn to make independent decisions.

To minimize the harm emanating from a computer, it is necessary to adhere to standard standards. They imply regular ventilation of the room, an LCD monitor, and special furniture.

Improper organization of the workplace can harm the child. However, even if all standards are observed, it is necessary to do exercises and walk in the fresh air.

Symptoms of radiation

At daily work while at the computer, you should know what symptoms indicate an “overdose.” Signs of excessive computer exposure may be confused with stress or overwork. Also, some associate them with old age. The influence of a computer on the human body is characterized by the following symptoms:

Memory loss, decreased concentration.
Fatigue, loss of strength.
Dizziness, frequent headaches.
Insomnia, irregular sleep.
Dry skin, itching and flaking, wrinkles appear.
Pain in muscles, arms and legs.
Frequent heartbeat.

In the future, radiation from the computer can lead to more disastrous consequences: inflammation of the lymph nodes, the birth of sick children, infertility.

Such symptoms and manifestations indicate electromagnetic hypersensitivity. However, this diagnosis is not recognized by all specialists. Many people believe that these signs can simply be suggested to themselves. But every day more and more people go to the hospital with similar complaints, mostly active PC users.

How to protect yourself from harmful radiation

Modern technology provides a lot of possibilities, but it also has a downside - dangerous electromagnetic radiation. By following some recommendations, you can minimize the harm your computer can cause to human health. The following protection methods exist:

Highest level radiation is located in the rear panel of the system unit, so the distance from it to another person must be at least 1.5 m.
The screen should be installed at a distance of 50-60 cm from the eyes, preferably in the corner of the room, to reduce harmful radiation from its walls.
It is necessary to reduce the length of power cables as much as possible.
Wet cleaning should be carried out regularly. The use of an ionizer will also additionally protect against PCs.
After finishing work, be sure to turn off the computer.
When purchasing a monitor, you should choose an LCD monitor marked Low Radiation, indicating a low degree of radiation exposure.
There are monitors with special protective screens, which help to minimize the harmful effects on the eyes when working at a PC for long periods of time.
The system unit should be positioned away from you.
Several computers in the room should be placed around the perimeter so that the center of the room remains free.

Special glasses

Among the ways to protect against computer harm to your health, you can also highlight computer glasses. By appearance They are no different from ordinary medical glasses, but they have a special coating applied to them. The glasses block the blue spectrum of rays emanating from the screen and protect against its unpleasant flickering.

In addition, they are coated with an antistatic coating that protects the eyes from the effects of a magnetic field, as well as from dust sticking to the lenses, which is very convenient during use.

Computer glasses have the following properties:

Protects eyes when working in bad conditions environment.
Reduces stress and strain on the eyes, while the user instinctively moves away safe distance from the screen.
Prevents the occurrence of dry eye syndrome.
Eyes wearing such glasses are much less tired during long-term work.

CT scan

Computed tomography allows for non-surgical examination and diagnosis of various diseases. However, research shows that this method has a detrimental effect on human health, increasing the risk of more dangerous diseases. At first after a CT scan, the risk of cancer increases by 35%, then this percentage gradually decreases.

There are maximum permissible doses of radiation per year that will not cause significant harm to health. Exceeding them is allowed only if absolutely necessary.

Computed tomography is a diagnostic method that is used last, when to replace alternative method it is forbidden. If it is possible to conduct an examination using ultrasound or other safe ways, it's better to choose them.

Computers and laptops enable millions of users to earn money, communicate, and have fun. However, nothing is more important than human health.

That's all today more people are starting to use computers regularly, so many people are wondering whether there is harm from using a computer. Computer like any other electrical appliance, emits electromagnetic radiation into the environment.

But how harmful is this electromagnetic radiation from a computer to human health?

Health hazards from computer radiation

Radiation from a personal computer travels in the form of electromagnetic waves high frequency. These waves are generated by almost all PC elements. Many medical experts prove that this computer electromagnetic radiation has Negative influence on the state of the body. Electromagnetic radiation is a disturbance of the electromagnetic field propagating in space, which was generated by a specific source. Certain electromagnetic waves may have a negative effect on the human body.

Radiation happens different frequencies, for which high-frequency radio radiation is considered the most harmful.

Radio emission from a CRT monitor is considered the most harmful; the impact power can reach several teras. But monitors based on a cathode ray tube are already becoming a thing of the past. The negative impact lies in the principle of operation of such a monitor. Inside there is a kinescope, inside of which electrons are accelerated and hit reverse side screen. It is this process that generates quite powerful. Such monitors have a particularly strong impact on vision, so it is not recommended to work on such PCs for a long time.

Liquid crystal or plasma monitors do not cause any harm in the form of radiation, since during their operation the generation of powerful electromagnetic fields is excluded. Such monitors can only harm your eyesight, but radiation exposure has nothing to do with it. The harm lies in the fact that in the process long work The eyes are strained too much, so it is recommended to take breaks while working.

IN modern computer generates the most intense radio emission CPU. On desktop computers this element is located at a certain distance from the user, so it will not cause significant harm. In the case of a laptop, the central processor is in close proximity to a person, so the exposure to radiation becomes stronger.

Many people have noticed that in a room where a computer has been running for a long time, the air becomes somehow heavy. This effect occurs due to exposure to ionizing radiation in the air.

During PC operation motherboards electrify the air due to which the molecules that make up the air around us are ionized. Ionized air under certain circumstances (for example, long stay in a room with electrified air) can be harmful to health.

Radiation protection

There is still some harm from a computer, so it would be useful to protect your personal computer from electromagnetic radiation. If the PC is equipped with a monitor that operates on cathode ray tube, it is necessary to work at a PC so that there is a distance of at least 1 meter between the face and the screen, so the radiation from the CRT monitor will not have too strong an effect on the body.

In case of desktop computer, system unit, should be as far away from the user as possible. If several computers work in one room (for example, in an office), it is necessary to place them so that there is at least two meters between the computers.

If you work on a laptop, it is advisable not to hold it on your lap. This will not only minimize the effects of radiation, but will ensure more efficient ventilation of the case. When working on a laptop, you need to place it on a flat surface, and just as in the case of a desktop, the distance between the user’s face and the monitor should be about one meter.

When working on a laptop for a long time, you need to periodically take short breaks, this will help rest your eyes.

Protection from electrified air

In order to protect yourself from air electrified by a computer, it is necessary to install air ionizers in the room. These are devices that refresh the air with negative ions, making breathing easy and pleasant. Ionizers also help to cope with other contaminants, for example, if you smoked in the room, then these devices will help remove the smell of tobacco from the room.

You also need to ventilate the air in the room where the PC is installed more often. In the case of an office, it is necessary to have efficient ventilation. Thanks to good ventilation, the air in the room will always be clean and fresh, no matter how many computers are working there.

Peripherals

Not a single computer can do without peripheral devices, mice, keyboards, printers, all this surrounds us. Recently, many users have started buying wireless peripherals for themselves. They communicate with the computer via electromagnetic waves, which causes additional electromagnetic radiation.

Therefore, if you do not want to deal with excessive radiation, it is recommended to choose peripheral models that communicate with the computer via a cable rather than electromagnetic waves. Such models will not only reduce the harmful effects of radiation, but will save you from the need to constantly charge batteries or buy new batteries. Also, wired models are much cheaper than their wireless counterparts.

Also quite strong radiation comes from sources uninterruptible power supply. After the measurements were carried out, it became clear what kind of radiation they produce, it turned out that it is comparable in power only to the radiation from monitors operating on the basis of a cathode ray tube. Therefore, if there is no way to refuse them, you need to hide these devices somewhere away.

Do plants help cope with radiation?

There is an opinion that indoor plants (especially cacti) can protect the user from radiation. Therefore, plants can often be found next to personal computers. Plants do not absorb radiation from the computer, so do not furnish workplace plants in order to protect themselves from such a phenomenon as an electromagnetic field. A small flower can only decorate the workplace with its appearance.

Conclusion

Despite the fact that a computer emits electromagnetic waves and causes, although not significant, harm to health, it remains an important element of life for many people. Many users understand that they should not spend too much time at the computer, but still sit in front of the monitor for several hours a day. Since today it is quite difficult to do without a PC.

If you feel tired, drowsy, or have a headache, this may be a symptom of excessive radiation. The best solution in such a situation there will be rest. You just need to get up from your desk for a couple of hours and everything will go away immediately.

Sticking to a few simple rules, you can minimize the negative impact of electromagnetic radiation on the body. But it is worth remembering that, even using the most modern means protection, it is impossible to completely protect yourself from radiation.
