Is wifi safe. Harm of wifi for health. Negative effect on the brain

A router, also known as a router, is a network device that allows you to choose the optimal direction of data transfer from the provider to computers, laptops and smartphones of users without wires.

The absence of wired communication means the transmission of information through electromagnetic radiation. Since routers operate at ultra-high frequencies, the question is completely legitimate - is the radiation from a wifi router harmful? The results of some studies refute these fears, while others confirm them. Let's look at the arguments on both sides.

Why radiation from a wifi router can be dangerous

Descriptive reasoning is not as weighty as precise specifications the device in question. So let's look at the numbers. Wifi router operates in the 2.4 GHz frequency range, and the power of ordinary routers is ~ 100 μW. When exposed to this frequency on the cells of the human body, there is a convergence and friction of the molecules of water, fat and glucose, accompanied by an increase in temperature.

Such frequencies are provided by nature for the exchange of intracellular information between organs and systems of the body. Long-term, external influence on this range from wireless local networks can introduce dysfunction in the process of cell growth and division.

The harm of wifi radiation is exacerbated by the radius and data transfer rate. An excellent illustration of this fact is the enormous speed of transferring a large amount of information when downloading videos, photos and other data. In this case, the transmitting medium is air, and the carrier frequency is this very medium-wave frequency range. And, since our cells are able to transmit and receive energy at different frequencies, the negative impact of the frequency range of the router is quite acceptable.

Inhabitants apartment buildings may be affected by many routers installed in neighboring apartments. brick walls And metal constructions only partially reduce the range of the router, but do not completely delay its radiation. Add to this wireless Internet access points in offices, shopping centers, cafes. It becomes clear that a person is under the influence of radiation from a wifi router almost around the clock.

Moreover, many users do not turn off the wifi router even at night. Summarizing this information, we can conclude that our body is in constant struggle with this aggressive factor. Perhaps that is why even a night's sleep does not bring many full recovery of strength, but the immune system does not protect us well from many infections and viruses.

Is a wifi router really that bad?

Of course, you have to pay for the convenience of wireless Internet use. But health is too high a price. Is radiation from a Wi-Fi router so dangerous?

To assess the effect of this radiation on the human body, a special parameter was introduced, called the absolute optical power of the radiation. Its unit of measure is 1 decibel milliwatt (dBm). The average power of a mobile phone is 27 dBm, while the same value for a router is 20 dBm.

Further, the router is never located at such a close distance as a mobile phone. Usually it is 1-2 meters. Do not forget that the radiation power decreases in direct proportion to the increase in the square of the distance to the "culprit" of the radiation.

How to reduce radiation from a wifi router

If, somewhere in the subconscious, anxiety still lingers, you can try to reduce the radiation of the router. Each of the devices for this purpose provides for signal strength adjustment. Few people pay attention to this function, and almost all users have routers, while maintaining factory setting turned on at full power. By setting the transmitter power to 50%, 25% or even 10%, you can significantly reduce the radiation dose and coverage area.

And, following this operation with neighbors, you can reduce the level of exposure by tens and hundreds of times. Moreover, manufacturers often unreasonably overestimate the power of these devices to increase the number of sales.

Is it possible to protect yourself from the radiation of the router? Of course, the radiation of the router affects a person. But how great is the harm of Wi-Fi radiation, there is no definite answer yet.

But there are these numbers:

the signal strength of a Wi-Fi router is 100,000 times weaker than that of a microwave;
radiation from two routers and twenty laptops is equivalent to exposure from one mobile phone.

If these impressive comparisons do not reassure the most inveterate skeptic, the following simple rules how to protect yourself from wifi radiation:

install routers at a distance of at least 40 cm from your workplace, and even more so do not sleep next to the included router;
turn off your access point if you do not intend to use the Internet;
Don't keep your laptop on your lap.

Technologies to protect against electromagnetic smog

The background created by various sources of electromagnetic radiation is called electromagnetic smog. Naturally, attempts are being made to protect oneself from all these pathological influences at once.

Entrepreneurial manufacturers have launched the production of wallpapers that can shield Wi-Fi radiation coming from neighboring apartments. You can buy them through foreign online stores. However, this particular product will interfere with the transmission of the Internet to other rooms within the apartment.
A new product has appeared on the health market - a corrector of the functional state of the body (FSC). Among the wide range of products for this purpose, we offer a fabric blanket with carbon thread. The material for creating such bedspreads is a special bipolar fabric that can reflect electromagnetic radiation from computers, wifi routers, phones and other household appliances.

To summarize - the above information is based on 4 parameters that allow you to give an objective assessment of whether a Wi-Fi router is harmful to health:

frequency;
power;
distance;
time.

Each of them works in favor of the theory about its negative influence.

And although today there is no real facts, which can confirm that it was wifi networks that caused this or that disease, compliance with security measures will not be superfluous. In addition, while humanity has no data on the impact of microwave radiation on future generations.

We can no longer imagine our lives without modern devices. At home, at work and at school, on the road and on vacation, we use mobile phones, tablets, e-books, laptops… Wi-Fi is available in many public places. But how dangerous router and harm wi-fi, we will consider in this article.

This allows us to work outside the office, keep abreast of the news, constantly communicate and not miss a single event in the lives of our relatives and friends. But, as studies by scientists have shown, not everything is so simple. It turns out that routers that transmit a Wi-Fi signal, along with a blessing, also carry danger. Danger to our health.

What is the disadvantage of wireless internet?

Electromagnetic radiation from Wi-Fi sources is a constant irritant for the nervous system and brain. In rooms with a constantly working router, people quickly get tired, their pressure increases, their heartbeat quickens, and their head hurts.

Parents note in their children an increase in irritability and aggressiveness and a decrease in attention. And scientists believe that the reason for these negative phenomena is the presence in our lives of modern mobile devices that constantly emit harmful electromagnetic radiation into the surrounding space.

Due to the widespread use of wireless networks, a reasonable question arises, is Wi-Fi harmful? Indeed, in our time, a wireless router is available in almost every family. There is an opinion that Wi-Fi not only harms human health, but also opens up access to various viruses that can damage a computer. Is it so?

The effect of radio emissions on humans

In order to understand whether Wi-Fi is harmful to health, you should understand what kind of connection it is and how it works. The full technology is called WirelessFidelity, which means "Wireless high-precision data transmission" in Russian. The connection is made via radio waves. In simple words It's a normal radio.

Now think, is it harmful to listen to music on FM radio stations? However, despite this, scientists are still arguing about the dangers of Wi-Fi. At the same time, it is still not possible to prove that such a relationship is detrimental to health.

Pay attention to the following facts:

It has been scientifically proven that the power of radio emission from a Wi-Fi router is 600 times lower than the permissible and safe for human health standards.
A group of British scientists conducted a number of studies in educational institutions regarding the study of radiation power and its effect on the body of children. At the same time, wireless routers and mobile phones with 3G connection were taken into account. As a result, it was proved that the power of radio emissions from the phone is three times higher than from the router. Professor Laurie Chellis has officially concluded that the harmful effects of Wi-Fi on human health are a myth. That is, the technology is absolutely safe. The only clarification is to not keep the laptop on your lap. However, other scientists have said that the radiation is so small that even in this case there is no danger.
Wireless access points operate on the same wavelength as conventional microwave ovens - 2.4 GHz. But at the same time, a kitchen appliance emits radio emissions that are 100 thousand times higher than the radiation from a Wi-Fi router. This was proven by scientist Malcolm Sperrin during his research. However, it is known that even microwave ovens, subject to high-quality assembly (good tightness), do not pose a health hazard. We are constantly surrounded by various devices that have much more powerful radiation: radio waves from mobile communications, all kinds of household appliances (TVs, radios, and so on).

Which is more dangerous: 3G or Wi-Fi?

Many people ask the question, what is more harmful - 3G or Wi-Fi? The radiation power of a mobile phone reaches 1W at a frequency of 0.9 GHz. At the same time, the maximum power of a wireless access point operating at a frequency of 2.4 GHz does not exceed 100 mW. A home cordless phone that operates on the same frequency emits 0.5-0.9 W.

This suggests that the impact of Wi-Fi radiation is significantly lower than that of 3G. The result is the following picture: it is impossible to say how much Wi-Fi is harmful to health, but at the same time it is reliably known that this technology causes significantly less harm than household appliances that surround us.

Can viruses get through Wi-Fi?

This is nothing more than fiction that has no basis. Such conclusions could be made only by inexperienced users who do not use antiviruses and go to suspicious sites. Having caught a virus on one of the dangerous pages on the Internet, the user concludes that the matter is in Wi-Fi.

But this technology only distributes the Internet over the air. The Internet itself is no different from the one that goes through the provider's cable. Moreover, most router models have internal protection that reduces the risk of malware penetrating your computer.

The only danger lies in the possibility of hackers hacking the network, but that's another topic. At the same time, you can configure network protection in the access point settings: set a complex password and choose the most reliable type data encryption.

How serious is the damage to wi-fi?

To find out, let's figure out what is wifi anyway? We open Wikipedia, where we read that the name comes from the English Wireless Fidelity, which means “high-precision wireless data transmission”, and is nothing more than a family of information transmission over radio channels. RADIO! Has anyone harmed their health by listening to the radio? To date, scientists have not come to a consensus on the dangers of wifi, but no one has been able to prove the harm to human health.

In general, all the noise came from the head of the British Ministry of Health, William Stuart, who had information about alleged changes in people's health from minor radio waves.

Let's turn to the facts, the opinion of experts:

It has been proven that the level of radiation that comes from wifi devices is 600 times lower than the norms of radio magnetic radiation that are acceptable and harmless to humans.
The BBC and a number of British scientists initiated a study in schools on whether wifi is harmful. The strength of radiation from mobile phones and wifi routers was measured. As a result, it was revealed that the level of radiation of the latter is three times higher. And Professor Laurie Chellis has officially stated that there is no harm to health from wifi, "unless you keep your laptop on your lap." Although the other members of the commission said that the radiation is so scanty that even this is not dangerous.
Wi-Fi and microwave devices operate on the same wavelength (2.4 GHz), but the radiation from a kitchen appliance is 100,000 times higher, which was revealed as a result of research conducted by another professor, Malcolm Sperrin. By the way, high-quality (hermetically) made microwaves also do not let anything through and do no harm.

And now let's remember what surrounds us in everyday life?

A cell phone is in everyone's pocket. And even if you don’t have it, then the neighbor has it, and the signal from the cellular operator does not choose through whom it should go to the neighbor’s phone - the rays penetrate your house up and down.
There is a microwave, if not in every, then in every second kitchen.
Everyone has a TV.
We all walk in parks and sit in cafes, wait for a train at the station or a flight at the airport, study at a university or work in an office - and most of these public places have wifi. Even some commuter buses already have it!
There is no point in talking about radiation from various kinds of industrial or military sources - we are all under their "cap".

In the end, what do we have?

It is impossible to say exactly how much wifi is harmful. But it is reliably known that the signal from WiFi causes much less harm than the vast majority of others. household appliances that we use every day.

But if you are still afraid of its possible impact, then it is enough to follow some simple rules to be calm:

Do not keep the device that receives the signal on your lap, but rather away on the table.
If possible, put the wifi router away from the place where you constantly sit or sleep.
Turn off the router if you are not currently working with the Internet.
Due to the impossibility of thoroughly studying the degree of harm, it is desirable, if possible, to protect small children from it, so as not to strain the young developing organism with additional, albeit insignificant, radiation.

All of the above does not apply to 3G mobile USB modems, because they receive a signal from mobile operators, and therefore radiate in the same way as cell phones. So you need to pay more attention to observing these precautionary rules when working with them than to the usual wireless Wi-Fi generated using a router connected to cable Internet.

This technology only distributes the Internet without wires - the Internet itself remains exactly the same as in your cable. The only danger can only be a hacker breaking into the network, but that's another story. So follow the minimum elementary safety rules that can be attributed to any modern household appliance and are described in more than a dozen instructions for their operation, and use it to your health!

How to reduce the influence of WiFi?

Doctors have proven that the consequences of using WiFi are:

Deterioration of memory and concentration.
The onset of a migraine.
The occurrence of joint pain
The development of tumors, even changes in genes are possible.
A decrease in potency in men, radiation negatively affects the quality of sperm.

It has not been officially proven, but still doctors are inclined to believe that the increased number of cases of the disease, Alzheimer's disease, cancer and dementia is associated not only with the use of mobile phones and laptops, but also with the wireless WiFi network.

If you do not want to change the router to a modem with wires, but want to reduce the harm of Wi-Fi, you should use some precautions:

Do not press while talking mobile phone to the head, it is advisable to use a headset.
The WiFi access point should be placed no closer than a meter from the place where a person usually sits, hangs out or sleeps. It is unacceptable to place the router above the bed.
You can not be near the included router.
It is necessary to turn off the router if no one uses the Internet.
In public places, it is advisable to install one WiFi network for all devices.

In this situation, each person evaluates the risks to their own health, but still it is worth considering the seriousness of this problem, because many citizens of the States and Europe strongly opposed the use of WiFi routers in homes, schools and kindergartens. Maybe not in vain?
http://tvoirouter.ru

Although the level of electromagnetic radiation from wireless transmitters is below official quotas, talk about the dangers of Wi-Fi for health not only continues, but also gathers supporters who advocate limiting the use of technology. The main speculative argument was the health of children.

Opinion of experts and media:

According to the Times Online, in September 30 scientists signed an international resolution calling for a "complete and independent review of scientific evidence dangerous exposure to the existing electromagnetic field around the world. Similar initiatives are emerging at the local level - the Irish Medical Conservation Association has addressed the state authorities with the same proposal.

In a number of British schools, at the request of panicking parents, wireless networks were dismantled; in Austria, the Salzburg Health Department recommended against the use of wLAN and cellular communications in schools and kindergartens; the Vice-Chancellor of the Canadian University of Lakehead, where they got rid of Wi-Fi, links exposure to radiation with behavioral and physiological changes in students.

According to experts convinced of the dangers of technology, children are at particular risk because they have a thinner cranial bone, and the nervous system is in the formation stage, and in the future, due to the development of wireless technologies, exposure to radiation will only increase.

With regard to studies that have proven the safety of mobile phones in terms of compliance established standards, according to Phillips, these standards concern short-term exposure, but the body, constantly exposed to weak electromagnetic vibrations, of course, changes. He cites as an example the observations of Latvian scientists, who noted a decrease in motor functions, memory and attention in thousands of children exposed to radiation at the level of wLAN transmitters.

According to Michael Clark of the British Health Protection Association (HPA), concerns about Wi-Fi, based on reports of the dangers of mobile phones, are unfounded. He cites international studies, according to which the radiation from Wi-Fi is about 0.00002 of the maximum set in the world, while a child using a mobile phone receives up to half of the permissible level.

In general, experts agree that electromagnetic waves undoubtedly affect people's health, but for everyone in different ways, and the level of a dangerous dose is a relative concept. For example, in Sweden they counted 5% of residents sensitive to radiation, and in the capital of the state, many people use special protective screens in their homes. Again, the causes of ailments aggravated by exposure to electromagnetic waves are not limited to them.

To top it all, the scientific community, not without the help of journalists, sowing panic among parents and suspicious Internet users, recalls that it is too early to discuss the harm from radiation, since the current technological environment exists and has not been observed for a long time for the scientific consistency of such conclusions.

Wi-Fi router harm or benefit?

A huge segment of people are consumers of new Internet technologies. Every year there is an increased trend of further growth. People can no longer imagine their lives without the Internet. However, every year famous scientists unanimously talk about the dangers of wireless Internet. Is a Wi-Fi router harmful to human health? What effect does this device have on the human body and should it be abandoned?

Some scientists believe that a person receives enormous harm from Wi-Fi radiation. And this happens only when the device is constantly in a state of continuous operation. Can it be avoided or reduced?

The principle of operation of the router

To get an answer to the question of whether wi-fi is harmful to health, a person can only understand the principle of its functioning. This device has the original name Wireless Fidelity. Translated into Russian, this means that data moves from one device to another using special radio channels. It was on the basis of this fact that scientists were able to determine what harm such a router carries. The negative impact is 600 times lower than the minimum indicator of harm to the body. Therefore, in an apartment, a Wi-Fi router is not harmful.

A colossal number of experiments conducted to answer the question what is harmful wifi radiation for health, has led to the fact that only a large number of such devices can be dangerous. It should be noted that the harm of wi-fi for health is slightly higher than the harm from a cell phone.

Serious harm cannot be obtained from the router, but there are still some negative factors. By the strength of the negative impact on the body, this device overtakes even a microwave oven. It will not be possible to completely get rid of negative factors, but they can be reduced thanks to some important tips.

Router Danger Warning

People need to understand that any radio signals have a certain effect on atoms and other elements of the human body. Doctors confidently declare the strong harm of a Wi-Fi router, which has a negative effect on:

Vessels associated with the human brain. The harm of Wi-Fi radiation on the human brain has been proven by a group of scientists through several experiments. During their course, it became clear that this device leads to spasms of blood vessels and a significant deterioration in concentration.
Children's body. The thickness of the skull of a child's body is much smaller, so the effect on the brain is several times stronger.
The potency of men. Wi-Fi is harmful to men's health, it affects the death of spermatozoa. In the normal state in the male body, about 14% of dead spermatozoa, while in the irradiated, more than 25% of the dead.

Scientists explained to people why Wi-Fi is harmful. Electromagnetic waves have a negative effect on people. It is possible to reduce its impact by reducing the time spent at the computer and laptop.

How can you reduce the negative impact of the router?

If you are still interested in the question related to whether radiation from a wi-fi router is harmful, and it seems to you that you are developing a phobia, then you can try to reduce its effect on the body. Each device has a signal level control button. Not all people are well acquainted with it, so they rarely use it.

You can set the power to 50, 25 and even 10%, which will significantly reduce the level of human exposure. If you are still wondering: “How harmful is the Wi-Fi in the apartment?” Then by reducing the power, you can become completely calm about this.
Many manufacturers often set the maximum power completely unreasonably. You can work at lower signal strengths.

The main rules to reduce exposure to a large extent:

the router should be no closer than 40 cm from the workplace;
it is forbidden to sleep nearby with the router turned on;
you can not constantly turn off the access point if you are not going to use the network in the near future;
try not to keep the laptop on your lap with the network turned on via Wi-Fi;
often, take evening walks in the fresh air.

Benefits of Using a Wi-Fi Router

There is a negative impact, but it is present in minimal quantities. Is it worth it because of this to abandon this device? In order for the answer to be the most balanced, you should understand the positive aspects of the device.

The main advantage of wireless Internet is its mobility.

Due to the absence of any wires, it becomes possible to use it in various places. Such places can be the premises in which conferences are held.

In addition, it should be noted that several people can connect to such a network at once. The file transfer speed in this case will be slightly lower, because it will be shared between all users, but this figure largely depends on the Internet provider.

Technical solutions for protection against electromagnetic radiation

Wi-Fi in the apartment creates a certain background, called electromagnetic smog. Scientists are taking a variety of ways to protect people from this influence. Well-known creators of routers have released a line of special wallpapers that can prevent the penetration of Wi-Fi radiation from neighboring apartments. You can buy such a product in online stores. It is worth saying that the wallpaper can become a kind of barrier for transmitting a wireless network to other rooms in the apartment.

In addition, there is such a product as a corrector of the functional state of human health, to which a special fabric cloth with carbon thread is attached. To produce such materials, a special bipolar fabric is used, which actively reflects electromagnetic rays received from various electrical appliances.

Laying wires for connecting the Internet will someday become a mandatory part of the design of a new building, but now people decide this issue on their own. For the convenience of using the network, people often put a router and many people have a question: is Wi-Fi harmful to health? The factors affected by this instrument are described below.

The negative impact of Wi-Fi on the human body

In every house where there is a laptop and a modern smartphone, there is a Wi-Fi router so that you can access the Internet anywhere in the apartment. Adults often worry about how Wi-Fi affects health. People do not fully understand how radio signals affect the body. The question of whether a Wi-Fi router is harmful to health has been studied very carefully and the results of the studies sometimes gave different facts. For example, medical professionals claim that the harm from Wi-Fi extends to:

children due to physiological characteristics;
vessels of the brain;
male reproductive capacity.

These are the main areas for which statistics were collected. At the same time, there is data that says that the impact of the router is extremely insignificant on health when compared with other devices, for example:

a microwave oven has a signal strength 100,000 times greater than that of Wi-Fi;
twenty laptops and 2 routers generate the same radiation as 1 mobile phone.

Influence on the vessels of the brain

When scientists decided to find out if the router is harmful to health, they conducted experiments that would affect different parts of the human body. One of the first directions is the effect on the vessels of the brain. This issue was dealt with by Danish specialists who conducted a check with schoolchildren. Each child was asked to put a phone with a Wi-Fi receiver turned on under the pillow.

In the morning they took measurements of the condition of the children. It was found that most of them have vasospasm, a decrease in concentration. This experiment cannot be called "pure", because only children participated in it, whose skull is thinner than that of an adult. In addition, the test subject could receive most of the radiation from the device itself, and not from the waves that the Wi-Fi network uses. The harm of these frequencies for the child's body remains an open question.

Harm from a Wi-Fi router on a child's body

The harm of Wi-Fi to the children's body is spreading due to a thinner skull. What was said above. WHO has made an official statement that Wi-Fi is harmful to the health of the child due to the electromagnetic radiation that the access point distributes and the mobile phone or computer receives. However, the organization does not have strong, clear arguments, so the harm from Wi-Fi remains in the group of unproven risk.

Harm from Wi-Fi radiation on male potency

Another area in which the harm of Wi-Fi was tested was the reproductive ability of men. To study the doctors took two samples of sperm, which were placed in different conditions. First, a spermogram was performed, showing the number of active, dead spermatozoa. One sample was placed near a computer that was connected to the Internet and downloaded files. The second was placed in a normal environment without the presence of waves on the cleanliness of the router.

It should be understood that the harm from Wi-Fi radiation on male potency and how radiation affects the viability of spermatozoa. In the sample that was next to the computer, 25% died, in the second - 14%. This suggests that the wireless signal is detrimental to sperm health. The specialists did another check that would check the quality of the sperm.

DNA was measured in live spermatozoa. Damage to the sample outside of electromagnetic waves was 3%, in cells near the wireless Internet - 9%. For the final test, another experiment was made on a computer with a wired connection. No change in the state of the material was observed. It is better for men not to put a laptop on their knees when the Internet is on.

Is Wi-Fi router harmful in the apartment

If you are worried about the harm from the Wi-Fi router, then you should think about refusing to use the TV, microwave oven, mobile phone and other electrical appliances. Each of them emits a certain amount of radio waves that affect human health. The harm from Wi-Fi is so insignificant that it simply cannot lead to any diseases. It is only necessary to follow some rules that minimize the impact of electromagnetic waves.

How to reduce radiation from the router

There are some recommendations for people who want to minimize the harm of Wi-Fi. There is no official confirmation of this phenomenon, but if you are afraid for your health, you can leave only a wired connection. Wireless data transmission will not be available, but the harmful background will also be reduced. If wireless communication in the apartment is still needed, then there are other ways to reduce the radiation from the router and its impact on the human body:

Try to install the device as far away from people as possible. If the router is at a sufficient distance, the harm from the waves will subside. Do not place the device near a sleeping or working place.
If Wi-Fi is distributed in the office, it is better to install one device with more power than several at different points in the room.
The wireless source sends signals constantly, so if you do not use the Internet for a long time, the device should be turned off.
Before going to bed, turn off the device, and turn it on in the morning.

These simple actions will help minimize the harmful effects of wireless technology on human health. These measures will not be redundant even if real harm it cannot apply a router, unless you specifically apply it to your head or put it on your knees. Really dangerous this species devices may be only for the child for physiological reasons.

In 1996, a method for wireless transmission of digital information was invented - Wireless Fidelity. Today, this technology is known to everyone as Wi-Fi (wi-fi). Wi-Fi router can be found in almost all offices and residential buildings. By transmitting a signal to computers, laptops, tablets and smartphones, it allows you to use the Internet anywhere in the room and even outside. But is it safe for human health? Is a Wi-Fi router harmful in an apartment? How to minimize the danger? These questions concern not only grandparents, who are wary of everything new that technical progress brings with it. Do not think that people who are afraid to use Wi-Fi are paranoid. Their fears for their health and the well-being of the younger generations have real grounds. How serious these grounds are, we will try to figure it out today.

What can be harmful Wi-Fi for a person

Wireless transmission of information is carried out by transmitting radio signals from one point to another. This is done at a purity of 2.4 GHz. It is she who is reserved in most states as a frequency at which it is allowed to transmit and receive radio signals without having a license to organize the activities of a radio station. Obviously, it is at this frequency that all household appliances that use radio waves operate. These devices include microwaves, cellular and conventional cordless phones, alarms.

It so happened that the specified frequency is included in the range of frequencies that the human body is able to perceive at the cellular level. How this may resonate with him years and decades later, no one really knows. Allegations that mutations can occur because of this, cancerous tumors can form, and other serious consequences can be observed, are unfounded. The arguments here are "logic", "intuition", "personal observations" and "life experience", but in no way Scientific research. No less groundless, due to the lack of such studies, are the statements about the complete safety of Wi-Fi.

Even the World Health Organization (WHO) got off on this with a vague answer:

“Based on recent in-depth monitoring of the scientific literature, WHO has concluded that there are currently no health effects due to exposure to electromagnetic fields. low level not confirmed. At the same time, there are some gaps in knowledge about biological effects, the issue needs further study.”

Confirmed Facts

It is obvious that the waves affect the human body, but how strong and dangerous this effect is is still not known for certain. We suggest not fantasizing, drawing a frightening dystopia in front of you, and not dismissing the problem, but analyzing some of the facts that we have at our disposal.

In Denmark, an experiment was set up to study the effect of Wi-Fi on the vessels of the brain. Children became participants school age who were asked to put a phone with Wi-Fi turned on under their pillow at night. The control group, respectively, did not hide anything under the pillow. Children who slept on the phone felt worse in the morning than their peers from the control group, many of them had vasospasm. The purity of the experiment may be questionable: the skull in children transmits radio signals better than in adults, the mobile phone itself (without Wi-Fi) could have a negative effect, the distance between the head and the device was very small. This is true, but it is obvious that there is still a negative effect on the vessels of the brain, even if only in children, from electromagnetic radiation. Conclusion: if small children live in the apartment, you need to try to protect them from the effects of Wi-Fi. If your child complains of headaches in the morning, it is possible that the reason is in the router that worked at his head, with the help of which you went out while the baby was sleeping to the global network.
Other scientists set up an experiment to study the effect of Wi-Fi on the male body. The experiment showed that the use of a router does not have the best effect on reproductive functions. This is not about the fulfillment of marital duty, but about the possibility of obtaining full-fledged offspring. If you're the type of male who wants to have healthy children, it makes sense not to carry a Wi-Fi-enabled laptop on your lap.
Another experiment was set up with the participation of Russian students. Some worked with paper media in a room protected from radio waves, while others accessed the Internet using Wi-Fi. The latter drank water more often and in larger quantities, which is why the researchers concluded that Wi-Fi speeds up metabolism. Good or bad, decide for yourself.
The harm from Wi-Fi does not exceed the harm from using a mobile phone and microwave. The power of a microwave oven is one hundred thousand times greater than the power of a router, although its radiation is short-lived. The impact of a router with Wi-Fi turned on in a year will be about the same as the impact of a mobile phone in 20 minutes of talking on it. Not only the signal strength is important, but also the time of its impact, and the distance to its source. The power of impact is inversely proportional to the square of the distance. If the router is more than a meter away from you, its effect on your body will be almost imperceptible. Adjust the power of the device: the factory settings are focused on the maximum signal strength, you can reduce it. At night, you can generally turn off the router. You may not even use Wi-Fi in your apartment at all. But let's be honest: if you care so much possible harm from Wi-Fi, wouldn't it be more logical to first refuse to use the microwave, watch TV and throw away the mobile phone?

Another fact suggests that the radiation from a working Wi-Fi router is negligible compared to electromagnetic waves from industrial and military facilities. This is just a tiny part of the global "electromagnetic smog" that has enveloped our planet. Even if in your apartment you decide not only to get by with a wired Internet connection, but also refuse a microwave, mobile communications, television and a computer in general, you will still be affected by waves from your neighbors' apartments, nearby office buildings, and other objects. . Strictly speaking, your sacrifice will be completely in vain.

Wi-Fi is harmful - everyone knows about it, but it is impossible not to use it. There are methods that can reduce the negative impact.

IN modern world every second uses Wi-Fi (wi-fi). Studies have shown that it is unhealthy and almost everyone knows about it. But we do not stop using it, because it is very difficult to imagine life without an Internet connection. But there are ways that can help at least a little protect yourself and your family from harmful effects. Let's figure out whether Wi-Fi is harmful to health in the apartment and how to minimize the harm.

Indeed, in every house there is a router. Radiation from this device can greatly impair health, and in some cases develop diseases. Scientists have done some research to understand how harmful radio signals are, and it turned out that more often they suffer from the effects of these signals:

Children's organism. This is due to its physiological characteristics.
male reproductive capacity.
Brain.

But do not immediately get nervous and get rid of the router. In fact, other studies have shown that the same has an intensity of about 1 thousand times more than Wi-Fi. But it also turned out that 1 ordinary mobile phone creates about the same radiation as twenty laptops and 2 routers.

Harm to children

As you know, young children have a very thin skull, and the router uses electromagnetic radiation, which they receive or the phone. Because of this, a severe headache, fatigue even after sleep, and all sorts of diseases can occur. However, there is no evidence for this, so one cannot be 100% sure. In any case, you should not put the router right in the child's room, this can lead to serious consequences.

Decreased male reproductive capacity

Scientists conducted a very light experiment that proved that radiation can have a bad effect on male potency. The researchers took 2 types of sperm, the first was placed in a room with a computer that was connected to the Internet and downloaded files throughout the experiment. The second was left in a room where there are no devices that cause radiation.

They tried to find out if the radiation from the router is dangerous and what effect this type of radiation has on the human body. They had to determine by the percentage of dead spermatozoa. At the end of the experiment, it turned out that in the sample that was placed next to the computer, 25% of the spermatozoa died, and in the second sample, only 14%. That is about 11% more. This experiment showed how bad Wi-Fi is for men's health. From here, the scientists concluded - you should not put the included laptop, phone or tablet on your knees. This restriction applies only to men.

Influence on the vessels of the brain

The experts decided to check whether the radiation is harmful and what harm Wi-Fi waves cause. As a result, it turned out that they also have a bad effect on the vessels of the human brain. The experiments were carried out on children, more precisely, with schoolchildren. They were told to put their phone, which is connected to a Wi-Fi network, under their pillow. In the morning the results were clear - many experienced fatigue, vasospasm, decreased concentration and other negative effects.

Of course, from this it could be concluded that the radiation from the router causes severe harm. But in fact, this is not the whole truth. During the experiment, only schoolchildren were tested, and their skulls are much thinner than those of an adult. In addition, scientists concluded that it was not the radiation from Wi-Fi itself that could cause harm, but electromagnetic radiation from the smartphone itself. That is, the experiment did not give any particularly important results.

Ways to Minimize Harm

Of course, there is harm from the router. But it is simply impossible not to use Wi-Fi, and this will not even help, since the same microwave oven, smartphones, laptops and other electronic devices do much more harm than the wireless network itself. So at the same time as Wi-Fi, you will have to give up all electronic devices and it's not that easy. You should not refuse Wi-Fi, because there are ways that can protect you and your family from the harmful effects of radio signals and electromagnetic radiation. Safety regulations:

There is nothing difficult in this, right? These simple ways will help neutralize the harmful effects, but, unfortunately, many simply ignore the safety rules. Do not do this, value your health and the health of your loved ones.
