Why is Wi-Fi dangerous? Can a Wi-Fi router installed in an apartment cause harm to health? How to reduce possible harm

Wireless Internet routers or Wi-Fi modems use the same radio frequency as microwave ovens. Does this mean Wi-Fi is dangerous to your health?

There is a huge amount of information on this matter on the Internet. There are various reasons for this, the main one being that demand creates supply. And the demand, in turn, arises due to the deterioration of people’s well-being, for which they are trying in every possible way to find an explanation. The harm of Wi-Fi in some articles is confirmed by references to a bunch of studies, while in others it is argued and refuted with evidence.

Of course, some Wi-Fi influence It clearly has an effect on health, because even the radiation from the monitor affects us. But the question is how significant is this effect on the body, and is it worth paying attention to it at all? Therefore, it is necessary to consider this issue from two sides, and not immediately put forward a separate self-confident opinion.

Arguments that Wi-Fi is unlikely to cause harm to health

Wi-Fi signal strength is approximately 100,000 times less than that of a microwave oven.
The intensity of a radio wave, according to the inverse square law, just like that of light, sound and the force of gravity, decreases by a factor of two as it moves away from the source. In other words, the signal level drops very quickly. Under normal conditions, Wi-Fi intensity is so low that it's not worth worrying about - it's just part of the "" that radio and television signals, electrical cables, electric motors in household appliances, and the universe as a whole also generate.
Often, the wavelength of Wi-Fi signals (12 cm) is approximately the same as the cosmic background radiation (0.001 - 0.5 m) that affects us when we go outside. And this cosmic radiation influenced our ancestors in stone caves, so we are partially prepared for it.
The electromagnetic spectrum includes waves from very long waves—radio frequencies—to very short waves—gamma radiation. At the same time, the light visible to us is somewhere in the middle. We know that types of ionizing radiation with wavelengths shorter than light are generally dangerous. Examples include ultraviolet (UV) rays, x-rays, and gamma rays. Ultraviolet part sunlight, of course, is also dangerous, which is why sunscreens were invented.

Non-ionizing wavelengths, which are higher in frequency than light, are generally not dangerous. These include infrared rays and radio waves. With a frequency of 2.45 GHz, Wi-Fi travels in the microwave range, in which baby monitors and mobile phones also operate.

Of course, it is possible to do dangerous things with radiation. Sun rays with the help of curved mirrors can set objects on fire, waves in a microwave oven thanks to a magnetron and high power boil water. Can even be used under high pressure a stream of water to pierce steel, but this does not mean that a person will die from taking a bath or standing under a fountain.

The mobile phone is near the brain during a conversation, while Wi-Fi router It may well be in another room. And according to some estimates, a person receives a larger dose of microwaves from one 20-minute phone call than from a year of exposure to Wi-Fi, the source of which is not directly near him.
Twenty laptops and two routers are roughly equivalent to one mobile phone under standard usage conditions.
The World Health Organization, which has studied this topic in depth, says: “In the field of biological effects and medical applications of non-ionizing radiation, approximately 25,000 papers have been published over the past 30 years. Despite some opinions that there is still some research to be done, scientific knowledge in this area is now more extensive than for most chemicals. Based on a recent in-depth review of the scientific literature, WHO concluded that evidence does not currently support the existence of any health effects from exposure to electromagnetic fields low level. However, some gaps in knowledge about the biological effects exist and require further research."

Arguments that Wi-Fi may pose a potential health risk

In the summer of 2011, the World Health Organization designated electromagnetic fields that come from Wi-Fi, cell phone networks, radio signals, microwave ovens, and cordless home phones as "possibly carcinogenic" agents, along with other things (such as coffee) for which there is evidence harms are not yet clearly confirmed.
There was a case where a woman doctor noticed that her family members were experiencing sleep disturbances, heart palpitations, migraines, and general poor health, and it all started in the same week. These painful sensations continued further. After eliminating all other possible causes, she turned off the router and they felt better. Fortunately, they did not live in an area littered with electromagnetic fields from demons. wired technologies from nearby houses. Now, of course, the family uses a wired Internet connection, and the health problems have not returned.
There are results from a number of studies (2009-2014) on the effects of microwaves with a frequency of 2.4 or 5 GHz (Wi-Fi) on animals and people, which confirm the negative impact on many body functions. According to their results:

harmful effects of radio frequency waves emitted from conventional devices Wi-Fi to the testes of growing rats;
when using laptop computers connected to the Internet via Wi-Fi, the motility of human sperm decreases and the fragmentation of sperm DNA increases;
modulation demon wired network(2.45 GHz) caused toxic oxidation of melatonin in the mucous membrane of rats;
as well as a huge number of other results, including effects on the autonomic nervous system, heart rate, brain and spinal cord, effects on the kidneys during pregnancy in rats, etc. All this can be seen in more detail.

It is impossible in most cases to be far from the source of Wi-Fi waves while using it. After all, even if the router is in a distant room, the device with which you use the Internet (laptop, tablet, smartphone) itself acts not only as a receiver, but also as a transmitter electromagnetic waves. Therefore, for example, even a smartphone in your pants pocket with Wi-Fi always on creates an electromagnetic field near your genitals. And they are expected to be one of the first to be affected by Wi-Fi.
Wi-Fi can have the strongest impact on the body in children. For example, a radio-controlled toy can cause no less harm, but the period of its operation in comparison with one working in Wi-Fi at home the source is insignificant. This is considered to be an adverse effect wireless internet may appear after many years.
They started installing Wi-Fi in schools in Israel, several years have passed since then. In 2011, a commission in Europe issued recommendations to ban Wi-Fi and WLAN in schools, as, in their opinion, it could harm the health of students. Some countries did just that. There are lawsuits going on in Israel in which parents are demanding this be done. And France has generally introduced a ban on any type of wireless connections in schools, incl. and mobile communications.
There are results of studies conducted on plants, for example, on watercress by schoolgirls from Denmark. Seeds exposed to Wi-Fi did not germinate. By the way, Denmark generally holds the record for such evidence of the harm of electrosmog.
It is no longer schoolchildren, but scientists from the same Denmark who, through experiments, have proven the negative impact of Wi-Fi on the human brain and indoor plants. Although this is a dubious source. During their experiments, schoolchildren had to put a smartphone with Wi-Fi turned on under their pillow at night, after which the next day they experienced vascular spasms and poor concentration. But this sounds very subjective and not very convincing. In the second case, they noticed a clear disappearance of indoor flowers in the room where the wireless Internet router was located.

Conclusion

Direct official harm to Wi-Fi, as well as any other similar sources of radio waves ( mobile network, radio-controlled devices, Bluetooth headsets, home radiotelephones, etc.) per person per this moment not proven. Although a lot of research has been carried out on this matter, as a result of which, it seems, Wi-Fi was harmful, but also often its absence.

The main problem is the arbitrarily subjective results, in which, in the case of various negative consequences, the specific process of their manifestation was not justified. But also, everyone understands that usually there is no smoke without fire. Many people claim that they have experienced general malaise, which is possibly caused by the electromagnetic field emanating from a wireless Internet source. Although there were many more cases when health problems manifested themselves in those living near antennas providing mobile communications.

You should be especially careful with children, whose health is most likely to be affected by Wi-Fi. After all, children are more susceptible to radiation than adults. Also, some tips may help to minimize the possible harm from this modern technology.

Recommendations for reducing possible harm from Wi-Fi

Use a distant location as a signal receiver and transmitter Wi-Fi antenna, not the device itself. This is primarily suitable for users of desktop PCs that are not initially equipped with Wi-Fi module. But it is unlikely that laptop owners will connect such an antenna if almost all of these gadgets are equipped internal module for such a thing. But for tablet PCs and smartphones this method is not rational at all.
Try to make the most of cable internet without Wi-Fi. But tablets and smartphones are also left behind.
If Wi-Fi source If it’s not yours, then in most cases it is located either with your neighbors, or simply in another room, and at the same time the damage to Wi-Fi is minimal until you use it. For even more effective protection you can use foil or other reflective material from its field. A Faraday cage operates on this principle. For the experiment, you can wrap your mobile phone in foil and if you can’t call it, then the experiment was successful. But there are also building insulating materials that contain aluminum to retain moisture and heat. They can also help achieve the Faraday cage effect.
Turn off the Wi-Fi source in your home when not in use, rather than leaving it on overnight, as most people do. Also disable the function responsible for its operation in your phones, especially when carried in your pocket. And it is highly undesirable to place your mobile phone under your pillow or very close to you while sleeping, because even with wireless Internet reception turned off, this has an adverse effect.

Of course, few people will be willing to sacrifice their comfort in order to protect themselves from possible harm from Wi-Fi. But measures to protect children from this are worth taking. You should especially not allow Small child I spent the whole day in the room where the Wi-Fi router is located.

To put it simply accessible language, Wi-Fi is a wireless connection that makes it possible to transfer information from one device to another. The signal is broadcast by a modern device called a router or router. The device connects to an Internet cable and, using built-in antennas, transmits network data to one or more devices.

On the panels of mobile phones, tablets, TVs and laptops you can find the corresponding wifi icon, which indicates the device's ability to receive wireless network signals. This is very convenient, since anywhere in the city or home you can connect to a Wi-Fi network and receive free access to the World Wide Web.

Inventor and first person to show the world wireless connections, was not a man - it was a wonderful actress and beautiful American woman, Hedy Lamarr. In the 30s of the 20th century, she not only received amazing roles in films, but also successfully worked in the field of wide communication channels under the supervision of the US military. It was this woman who came up with the first decryption algorithms, without which the world would not have known about GPS, Bluetooth, Wi-Fi.

However, in those years there was no programmable equipment and the issue was resolved using mechanics. IN unique device the piano mechanism was introduced, and upon completion of the work it could broadcast 88 frequencies - according to the number of its keys. The result was an amazing device that transmits a signal to long distance and placed under the shell of a naval torpedo.

The invention was classified as “secret” for many years, and many years later, when semiconductors became available to scientists, Hedy Lamarr’s discovery was made public. Surprisingly, it was only in 1997 that the American Electronic Frontier Foundation decided to award the wise woman a medal for her long-standing discovery. Hedy refused to attend the ceremony, and her reaction to this decision was the sarcastic phrase: “Very timely.”

Harm

Is Wi-Fi harmful to health?

Computers and routers are present in almost every family, and few people think about how likely Wi-Fi is to harm. To determine the scale of the danger, it is necessary to refer to the exact technical specifications this device. A typical router operates at 2.4 GHz and has a maximum power of about 100 µW.

It is known that radio frequencies do not have the best effect on the human body, causing negative reactions in our body at the molecular level. Molecules of substances such as glucose, water, fats that make up the body, under the influence of frequencies, begin to move chaotically and come closer together, which leads to an increase in body temperature. Long term exposure Wi-Fi connection on the body can lead to disruptions in the formation, division and growth of cells.

Damage to Wi-Fi becomes most dangerous due to the fact that the data transmitted by this device covers a huge radius and moves very quickly. high speed. Air acts as a transmitting medium, and the flow of information moves along medium wave frequencies. And since our body is able to perceive and transmit energy emanating from devices with different frequencies, it passes through itself a huge number of streams emanating from the router.

Even the fact that you don't have a router in your home won't protect you from being exposed to a harmful Wi-Fi environment. Wi-Fi communications streams can come from neighboring apartments, and metal structures and brick walls only partially mitigate their harmful effects. Considering that in Everyday life Since we are surrounded by wireless Wi-Fi networks everywhere - in offices, shopping centers, we can conclude that a person is under almost 24-hour exposure to radio wave emitters.

Of course, all radio signals affect the state of our body. Scientists have proven that the most vulnerable to their effects are:

Human nervous system and brain
Male reproductive system

In addition, many users do not turn off their routers even at night, exposing themselves and others to the harmful effects of Wi-Fi radiation. Therefore, you should not be surprised that sometimes after a night's rest a person gets up completely exhausted, and the immune system cannot cope with the stress and weakens its defense.

This is not surprising, because in almost every house you can find up to a dozen wi-fi networks- in a cafe, on the street, etc.

Canadian scientists warn humanity about a new disease of this century - electrohypersensitiveness - disruption of the heart, suffocation, migraines, hypertensive crisis. In Sweden, people who are hypersensitive to electromagnetic radiation claim that they are allergic to wireless means communications.

Those hypersensitive to microwaves may experience insomnia, problems with memory and concentration, as well as depression, anxiety, and pain from exposure to microwaves. different parts bodies.

Benefit

Benefits of Wi-Fi

The advent of wireless communications has improved the quality of human life and opened up endless possibilities. The Internet has become accessible even where it is not possible to lay a cable - holding conferences and business negotiations has become available anywhere in the world.

Another undeniable advantage of this type of communication is that several devices can connect to one access point - and this is exactly what it does WiFi connection very prestigious and comfortable. Of course, the speed of information transfer in this case is slightly reduced, but it all depends on the speed of the Internet and the provider providing the service.

The dangers of Wi-Fi have been reviewed by multiple world health organizations, and experts have provided evidence that radiation from a router is 600 times below acceptable limits. Regular mobile communications are much more more dangerous than Wi-Fi radiation, and a year of using the router is equivalent to a 20-minute conversation on a mobile phone.

The harmful effects of Wi-Fi are not denied, but no one is going to limit its use wireless networks. What is the reason? It is banal and clear - corporations that produce televisions, telephones, computers, household appliances and latest devices with built-in Wi-Fi function If humanity abandons wireless technologies, they will suffer colossal losses. Therefore, every person should think about the need to fill their everyday life with trendy technologies, and if it is inevitable to avoid their introduction into everyday life, then at least take care of reducing harmful radiation emanating from the devices.

How to reduce the harm from Wi-Fi

It will not be possible to completely get rid of the frequency radiation of devices and reduce the harm of Wi-Fi to zero, but you can reduce its harmful effects in the following ways:

When purchasing and installing routers in the home, users do not pay attention to the fact that almost all devices have functions for adjusting signal strength. Basically, all devices support factory settings set to maximum flow strength. By reducing the power of the device by 25.50, you can significantly narrow the coverage area and reduce the harmful dose of Wi-Fi radiation.
During operation of the device, it is recommended to remain at a distance of about 40 cm from it. This especially applies to users who have to work in an area Wi-Fi coverage.
You should unplug your router at night and unplug it when not in use.
Devices that receive signals Wifi is better keep away from the body - do not put the laptop on your lap, and connect a detachable headset while using the phone.
You should install the router at home in a work area, away from bedrooms and places where children are most often found.
If possible, you should refuse Wi-Fi applications in favor of wired technologies, and in public places avoid places with wireless coverage.
The best option there will be the creation of one powerful point Wi-Fi access in the apartment instead of several radiation sources.

Certainly today wireless communications– this is comfort and convenience. And if you do not have the opportunity to protect yourself from harmful radiation, then you must take care of protecting children, because the child’s immune system, unlike an adult’s, is much weaker, since the child’s body is not yet fully formed. The child should not be allowed to be in the area of any dangerous radiation and try to protect children from long stays in the room where it is installed Wi-Fi router.

Modern man cannot imagine existence without the Internet. Many devices have Wi-Fi modules built into them. In restaurants and cafes there is a router that allows visitors to connect a laptop or smartphone to the Internet. There are also wifi lovers who buy a router for their home. But is there any harm from such radiation, does Wi-Fi affect a person’s well-being?

Does WIFI harm human health?

There is conflicting information on the Internet. There is evidence that wifi is harmful to humans, other authors claim that all radiation is harmful, and in comparison with them, Wi-Fi is safe. It is fashionable to talk about the harm caused by continuous radiation. But so far there are no hard facts proving that wifi is harmful to humans. After years of using equipment such as a router, such information may appear.

But these are relatively new technologies, so no studies have yet been conducted that would reassure or upset the public. Scientists claim that this radiation does not have a positive effect on living organisms, including human cells, but no one is talking about severe harm yet. Let's consider all the arguments for and against.

No harm

It is impossible to hide from radiation sources in the city

A person, especially if he lives in a city, in an apartment, surrounds himself a huge amount technology. Why do many people think that Wi-Fi is harmful to health?

Thus, the radiation intensity of wifi is 100 thousand times less than that of a microwave oven. This was proven by Professor Malcolm Sperrin, it is not so harmful.
The level of radiation emanating from the router and other devices is 600 times lower than the standards that are now considered safe for humans, if we take radiation standards.
A mobile phone is a device that is in everyone’s pocket: from schoolchildren to pensioners. We quickly became accustomed to the available device. Meanwhile, the harm from it is much greater. Researchers from the UK's Health Protection Agency say that a person who spoke on the phone for 20 minutes received the same amount of radiation as someone who used Wi-Fi for a year.
Professor Laurie Chellis made a statement in which he explained that Wi-Fi is not harmful to health if you do not keep the laptop on your lap, but put it on the table.
The power of electromagnetic radiation depends on the distance at which the radiation source is located. How longer distance, the less radiation: power is inversely proportional to the square of the distance. The router is located at some distance from the person, so it does not have a serious impact on his health, even if he installed it at home, in another room.

There are many sources of radiation around us: computer, TV, mobile phone. Even if you completely give up Wi-Fi, you will not be able to protect yourself from other waves. They are everywhere, and it is impossible to hide from them in the city.

Harmful

Research shows significant harm to health

But other studies show significant harm to health. According to this data, the influence of Wi-Fi is not safe, as they try to convince us of it.

Schoolgirls experiment

And not enough research has been done in this area, otherwise scientists would have found out that it affects human health. Danish schoolchildren, ninth graders, decided to conduct an experiment that you can repeat at home. This idea was prompted by their poor health, which they associated specifically with wifi.

They took lettuce seeds and planted them in 12 containers. Of these, six trays were placed in a room where there was no access to Wi-Fi, and the remaining 6 were placed in a room where there were two routers. After two weeks, it became clear that the seeds that were in the ordinary room had sprouted. And everyone else who was in the apartment with Wi-Fi suffered from radiation and died.

Biology teacher Kim Horsewad said her students' experiment sparked a lively discussion. Employees of the Karolinska Institute in Sweden want to repeat this experiment, but in laboratory conditions.

Affects concentration

Wi-Fi affects children's health

Danish scientists conducted several tests. They asked school-aged children to place a mobile phone with Wi-Fi turned on under their pillow in the evening. We measured the strength of radiation emanating from a mobile phone and from a wifi network router. In the morning the boys were examined. We found out that Wi-Fi affects the health of children, because the majority showed vascular spasms and deterioration of attention, they concentrated worse.

But these studies have shown the effect of radiation on children, but schoolchildren have thinner skulls than adults, so it cannot be said that wifi has a negative effect on everyone and is harmful.

For men's sperm

One cannot but be surprised by the results of studies proving the influence of Wi-Fi radiation on men’s health.

Experiment. For the experiment, 30 adult and physically healthy men were selected, and a sperm sample was taken from them. First, it was analyzed to confirm the number of active or dead sperm. Then the samples were divided into two parts and one of them was placed next to a computer connected to a wifi network. They experienced the radiation emanating from the devices. The rest were placed in another room.

Scientists have found that Wi-Fi negatively affects men's health

Results. The analysis showed that the sample that was affected by radiation suffered more severely - 25% of the sperm died in it, while in the other samples this figure was less - 14%. Scientists analyzed the samples and found that the radiation caused other changes. After measuring deoxyribonucleic acid, it became clear that in the surviving sperm of those who were not exposed to Wi-Fi, the change was 3%, and in the rest - three times more.

For the purity of the experiment, similar experiments were carried out, but with a computer connected to a wired network. Then the difference between the prototypes was not noticeable. The experiment showed that Wi-Fi radiation affects the quality of men's sperm, so those who are just planning to become a father should not use such Internet or do not keep a laptop on their lap.

How to protect yourself

IN Lately talk about the dangers of radiation. Increasingly, the question has begun to be raised that it causes cancer, dementia, heart failure, memory impairment, etc. However, there is no official conclusion that would confirm the harm of Wi-Fi. But in other countries (Germany, England, USA) the issue of banning wifi in universities, schools, and hospitals is increasingly being raised. Many people refuse to install a router at home, preferring to use another type of communication.

Phobia

But it is important that justified fears do not develop into a phobia, since there is no evidence yet to confirm the serious impact of radiation on human health. But some companies benefit from heating up the situation and making money on people’s fears. So, trying to protect themselves, some people buy clothes made of foil or cover their walls with wallpaper made of this material. And someone is profiting from this by selling rolls for $800.

How to protect yourself from the influence of Wi-Fi?

There are also those who leave their favorite job, friends, family and move to the northeastern United States, to the Green Bank settlement. This is a real refuge for those who are afraid of electromagnetic waves, because in an area of 33 thousand square meters there is no equipment, it is prohibited, just like cars with a gasoline engine. This zone appeared in 1958, and these innovations are not for the sake of human health, but for the sake of the accurate operation of telescopes. There is no television, radio, microwaves, cell phones or wireless internet.

People who have discovered sensitivity to electromagnetic radiation come here. They claim that it gives them pain, nausea, heart palpitations, etc. But WHO in most countries does not recognize this disease, despite the fact that 2-5% of Europeans and Americans experience these symptoms.

What to do?

How can those who do not want to leave civilization protect themselves?

For your computer, choose cable internet.
Remember that if the router is not near you (with your neighbors, in another room), the harm from it is minimal.
If you do not use the Internet, turn off Wi-Fi. In phones that you carry in your pocket, turn off the wifi function.
Protect your child from the effects of radiation. The baby should not play all day in the room where the router is located.
Don't keep your laptop on your lap.

And remember that the harm from wifi radiation is several times less than from the same mobile phones, so there’s no need to panic.

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

This allows us to work outside the office, keep abreast of news, constantly communicate and not miss a single event in the lives of our loved ones and friends. But, as research by scientists has shown, not everything is so simple. It turns out that routers transmitting wifi signal, along with the good they also bring danger. Danger to our health.

What are the harms of wireless Internet?

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

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

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

The influence 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 translated into Russian means “Wireless high-precision data transmission.” The connection is made via radio waves. In simple words- This is a regular radio.

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

Please note the following facts:

It has been scientifically proven that the power of radio emission from a Wi-Fi router is 600 times lower than permissible and safe standards for human health.
A group of British scientists conducted a number of studies in educational institutions to study the power of radiation and its effect on the body of children. In this case, wireless routers and mobile phones with 3G communications were taken into account. As a result, it was proven that the power of radio emissions from the phone is three times higher than from the router. Professor Laurie Chellis has officially concluded that harmful effects Wi-Fi on human health is a myth. That is, the technology is absolutely safe. The only clarification is not to keep the laptop on your lap. However, other scientists have said that the radiation is so small that even then there is no danger.
Wireless access points operate on the same wavelength as conventional microwaves - 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 research. However, it is known that even microwave ovens, provided they are well assembled (good sealing), 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).

What 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 at the same frequency emits 0.5-0.9 W.

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

Can viruses get through Wi-Fi?

These are nothing more than fabrications that have no basis. Such conclusions could only be drawn inexperienced users who do not use antivirus software and go to suspicious sites. Having caught a virus on one of the dangerous pages on the Internet, the user concludes that the problem is Wi-Fi.

But this technology only distributes the Internet over the air. The Internet itself is no different from the one that comes through the provider’s cable. Moreover, most router models have internal protection, which reduces the risk of penetration malware on computer.

The only danger is 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 select the most reliable type of data encryption.

How serious is the harm of Wi-Fi?

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

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

Let's look at the facts, expert opinion:

It has been proven that the level of radiation that comes from wifi devices, 600 times lower than permissible and harmless to humans standards for radiomagnetic radiation.
The BBC television company and a number of British scientists initiated a study in schools to determine whether wifi is harmful. The strength of radiation from mobile phones and wifi routers was measured. As a result, it was revealed that the radiation level of the latter was 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 negligible that even this is not dangerous.
Wi-Fi devices and microwaves operate at the same wavelength (2.4 GHz), but the radiation from a kitchen appliance is 100 thousand times higher, which was revealed as a result of research conducted by another professor, Malcolm Sperrin. By the way, high-quality (hermetically sealed) microwave ovens also do not leak anything and do not cause any harm.

Now let's remember what surrounds us in everyday life?

Everyone has a cell phone in their pocket. And even if you don’t have it, then your neighbor has it, and the signal is from mobile operator does not choose through whom exactly to go to the neighbor’s phone - the rays pierce your house up and down.
There is a microwave, if not in every kitchen, then in every second kitchen.
Everyone definitely has a TV.
We all walk in parks and sit in cafes, wait for a train at a 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 types of industrial or military sources - we are all under their “hood”.

In the end, what do we have?

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

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

Do not keep the device that receives the signal on your lap, but rather far away on the table.
If possible, place the wifi router away from the place where you constantly sit or sleep.
Turn off the router if you are not currently using the Internet.
Due to the impossibility of thoroughly studying the degree of harm, it is advisable, 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 are the ones who receive the signal from mobile operators, and therefore emit the same as Cell Phones. So, compliance with these precautionary rules when working with them should be taken with greater attention than with regular wireless Wi-Fi generated using a router connected to cable Internet.

This technology only distributes the Internet wirelessly - the Internet itself remains exactly the same as in your cable. The only danger can be hacker hacking networks, but that's another conversation. So follow the minimum basic safety rules, which can be applied 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 impact of WiFi?

Doctors have proven that the consequences WiFi usage is:

Deterioration of memory and concentration.
The appearance of migraine.
The occurrence of joint pain
The development of tumors, even gene changes are possible.
Reduced 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 Alzheimer's disease, cancer and dementia is associated not only with the use of mobile phones and laptops, but also with the WiFi wireless network.

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

You should not press your mobile phone to your head while talking; 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, spends time or sleeps. It is unacceptable to place the router above the bed.
You cannot be near the router that is turned on.
You need to turn off the router if no one is using the Internet.
In public places it is advisable to install one WiFi network for all devices.

In this situation, each person assesses the risks to his own health, but it is still worth thinking about the seriousness of this problem, because many citizens of the States and Europe are categorically against the use of WiFi routers in homes, schools and kindergartens. Maybe it’s really not in vain?

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

Expert and media opinion:

According to the Times Online, in September 30 scientists signed an international resolution calling for "a full and independent review of the scientific evidence of the dangerous effects of existing electromagnetic field Worldwide". Similar initiatives are emerging in local level— The Irish Environmental Medical Association has made the same proposal to the government authorities.

In a number of British schools, wireless networks were dismantled at the request of panicking parents; in Austria, the Salzburg health department recommended against the use of wLAN and cellular communications in schools and kindergartens; The vice-chancellor of Lakehead University in Canada, which got rid of Wi-Fi, links radiation exposure to behavioral and physiological changes in students.

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

As for the studies that have proven the safety of mobile phones in terms of meeting established standards, according to Phillips, these standards relate to short-term exposure, but the body, constantly exposed to weak electromagnetic waves, 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 levels of wLAN transmitters.

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

In general, experts agree that electromagnetic waves undoubtedly affect people's health, but on everyone differently, and the level of a dangerous dose is a relative concept. For example, in Sweden it was estimated that 5% of residents are sensitive to radiation, and in the capital of the state many use special protective screens. Again, the causes of ailments that increase when exposed to electromagnetic waves are not limited to them.

To top it all off, the scientific community, not without the help of journalists, is spreading panic among parents and suspicious Internet users, reminding that it is too early to discuss the harm from radiation, since the current technological environment has not existed and been observed long enough for the scientific validity of such conclusions.

Is a Wi-Fi router good or bad?

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

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

How the router works

A person can only get an answer to the question of whether wi-fi is harmful to health by understanding 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 based on this fact that scientists were able to determine what harm such a router poses. The negative impact is 600 times lower than the minimum level of harm to the body. Therefore, a Wi-Fi router in an apartment is not harmful.

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

It is impossible to get serious harm from the router, but there are still some negative factors. In terms of the negative impact on the body, this device is even faster than a microwave oven. You won't be able to completely get rid of negative factors, but they can be reduced with some important tips.

Warning about the danger posed by the router

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

Vessels connected to the human brain. The harm of Wi-Fi radiation on the human brain was proven by a group of scientists through several experiments. During their course it became clear that This device leads to vascular spasms and a significant deterioration in concentration.
Children's body. The thickness of the child’s skull is much smaller, so the impact on the brain is several times stronger.
Potency of men. Wi-Fi is harmful to the health of men, it affects the death of sperm. In a normal state, about 14% of dead sperm are in the male body, while in an irradiated body more than 25% are dead.

Scientists have 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 a router?

If you are still interested in the question of whether radiation from a wi-fi router is harmful, and you think 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 or even 10%, which will significantly reduce the level of human radiation. If you are still asking the question: “How harmful is Wi-Fi in an apartment?”, then by reducing the power, you can become completely calm about this.
Many manufacturers often set maximum power completely unreasonably. You can also work at lower signal strengths.

The main rules to greatly reduce radiation exposure:

the router should be no closer than 40 cm from the workplace;
It is forbidden to sleep nearby with the router turned on;
You cannot constantly turn off the access point if you do not intend to use the network in the near future;
try not to keep the laptop on your lap with the Wi-Fi network turned on;
Take evening walks in the fresh air more often.

Benefits of using a Wi-Fi router

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

The main advantage of wireless Internet is its mobility.

Due to the absence of any wires, it can be used in various places. Such places can be the premises where 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 among all users, but this indicator largely depends on the Internet provider.

Technical solutions for protection against electromagnetic radiation

Wi-Fi in an apartment creates a certain background called electromagnetic smog. Scientists are taking various ways to protect humans from this influence. Well-known router creators have released a line of special wallpapers that can block Wi-Fi radiation from neighboring apartments. You can buy such a product in online stores. It is worth saying that wallpaper can become a kind of barrier to the transmission of 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, which comes with a special fabric sheet with carbon thread. To produce such materials, a special bipolar fabric is used, which actively reflects electromagnetic rays received from a variety of electrical devices.

Complete and up-to-date information on the issue of the dangers of Wi-Fi, I personally agree that doctors and scientists do not agree on the dangers of Wi-Fi on health

Answer

It is indispensable in our lives. Nowadays, no one will be surprised by the presence of Wi-Fi in offices, shopping and entertainment complexes, beauty salons, restaurants and cafes, just in parks and on the streets and squares of big cities. At home, almost every family has several devices with Internet access; Wi-Fi helps solve the issue of simultaneous access. The router gets rid of wires getting tangled under your feet. Wireless technologies penetrate deeper and deeper into our everyday life.

But in parallel with this, many researchers, and ordinary users I am tormented by the question of how Wi-Fi affects our body? Some talk about harmlessness, others argue that the harm of Wi-Fi is quite noticeable. Let's look at some aspects of this issue.

A few words about Wi-Fi technology and the purpose of Wi-Fi routers

Wi-Fi is a wireless radio standard operating at a frequency of 2.4 to 5 GHz. For experimental purposes, the frequency can reach 20 GHz, but in everyday life such high frequencies do not apply. The data transfer speed is growing every day, and the level of protection is increasing.

At Wi-Fi assistance You can create a wireless network with Internet access in almost any room and connect many devices to it, such as laptops, tablets, phones, TVs and even watches. Unlike wired connection, via Wi-Fi you can connect practical unlimited amount devices.

Having a wireless network creates many conveniences, but is a Wi-Fi router in an apartment harmful?

The influence of electromagnetic waves on the body

The frequency at which the router’s transmitter operates affects the functioning of the cells of the human body, causing the molecules of water, glucose, and fat to approach and rub together, which entails an increase in temperature. Because of this, cells may not work correctly and fail.

When downloading large volumes, the data transfer speed increases. Data is transmitted over the air in the mid-frequency range. Since cells can receive energy at different frequencies, the possibility of harm to health cannot be ruled out.

Living in an apartment, we are exposed to radiation from our neighbors’ routers. Walls cannot completely protect us from waves. Plus, wireless points access systems are installed in cafes, offices, shops. In fact, each of us is exposed to radiation all day long. And many of us do not turn off the router even at night.

Wi-Fi router

Doctors have conducted repeated studies on the dangers of Wi-Fi for humans. Electromagnetic field radiation can cause symptoms such as insomnia, irritability, fatigue, and headache. Night sleep may not bring us proper recovery, and the immune system may not protect us from viruses and diseases.

Effect on cerebral vessels. Danish scientists suggested that some schoolchildren put a smartphone with Wi-Fi turned on under their pillow at night. Examinations showed deterioration of attention and the presence of vascular spasms. But since the participants in the experiment were children, one should not count on the purity of the experiment.

Impact on children. Because children's skulls are thinner, they are more at risk. Although the World Health Organization has reported that broadband wireless networks do not affect the body, it is electromagnetic waves that harm the body. At the same time, the organization emphasizes that there is no convincing evidence of the harm of radiation.

Impact on men's health. As part of the experiment, it was found that electromagnetic radiation affects sperm. In a sample installed on a computer with Wi-Fi turned on, 25% of the sperm died within four hours. Therefore, men should not abuse holding a laptop on their knees.

How harmful is Wi-Fi itself?

The main parameter affecting a person is the absolute optical radiation power, which is measured in decibel-milliwatts (dBm). The radiation power of a mobile phone is 27 dBm; the user receives the highest radiation when calling and searching for a network signal. The strength of the impact depends on the distance at which the phone is located from the owner and the duration of the radiation.

The radiation power of the router is about 20 dBm, and it is usually located a few meters from the user. And since the harm from radiation decreases in proportion to the distance from the device, then in comparison with a mobile phone, we can say with confidence that the radiation from a router has a much smaller impact on human health.

It is known that the range of Wi-Fi waves is the same as in microwave ovens. But the radiation power regular router approximately 100 thousand times weaker. This is another argument against great harm Wi-Fi that scientists are paying attention to. It can be argued that in terms of benefit-harm ratio, a Wi-Fi router is not the most dangerous device.

How to reduce possible harm

Despite the fact that no real harm has been proven, it is worth protecting yourself as much as possible, since electromagnetic radiation does not bring any benefit.

If possible and appropriate, connect to a wired network instead of a wireless one, this will protect your body from unnecessary rays.
Place the access point away from the places where you are most often.
Turn off your Wi-Fi router at night or when you are not using the Internet.

Conclusion

We hope that we helped you decide whether Wi-Fi is harmful. Remember that in a big city it is almost impossible to hide from electromagnetic waves, because we are surrounded by many sources: household appliances, laptops, smartphones and tablets, television signal, mobile operator towers.

Despite the statements of scientists and researchers, few people give up convenience and limit the use of wireless networks. In addition, the production of equipment is a huge business, and no one will radically change everything.

Decide for yourself whether it is worth exposing yourself to a certain risk or whether you can do without home Wi-Fi and find alternative ways to resolve the issue. No one will decide for you.

Do you think Wi-Fi is harmful? Could you refuse it? We invite you to share your opinion on this issue in the comments.
