Our life today is almost impossible to imagine without the Internet. Social networks, news flow, entertaining videos and much other information, without which it would seem impossible to exist even when you are far from home. The development of the Wi-Fi Internet connection industry makes its own adjustments to everyday life. However, is everything so safe and simple, is there a negative impact of Wi-Fi on the human body? Let's try to understand this issue.
What is a Wi-Fi signal and why do you need a router?
Wi-Fi is a type of signal using electromagnetic waves needed to receive and transmit data. The signal operates based on the wireless transmission of waves from one device to another. This connection helps users access the network from any device designed for this, be it a laptop, smartphone or tablet - if the device supports wireless connections, then you will be able to access the Internet.
In order to “distribute” a Wi-Fi signal, you need a special transmitter - a router, or router. It connects to the local network on your personal computer, thereby making it possible to access the Internet from any home device. A router greatly simplifies the life of a modern family, which has many gadgets that require an Internet connection.
You can purchase a router at a specialized hardware store. Nowadays a lot of routers are produced for any wallet. For home use, you can choose an inexpensive device with low signal output power. But a large company needs a high-quality router with high power.
Exposure from a router and other devices: comparison
The router is scary and makes me doubt its security, since it appeared not so long ago. It has been on the domestic market for less than 10 years. However, other electrical appliances that have been used at home for many years have a more serious impact. To fully understand whether the device is dangerous and can cause critical radiation, we compared the radiation from microwave ovens, smartphones and diffusers.
Microwaves turned out to be most harmful in apartments. Its waves, with prolonged action, can change the structure of internal organs. Because of this, products that lie at a two-meter distance from the stove will quickly spoil or become as if they were boiled. They cannot be consumed. If there are people in the place of the products, some will experience dizziness and fatigue after being near an electrical appliance for a long time.
Mobile gadgets (tablet PCs, smartphones) have shown that they are capable of emitting less radiation. They only harm the body if a person carries the gadget with him all the time, close to his body. Cell phones should not be kept in pockets near the groin. However, when used in moderation, the technique is not dangerous.
The safest device turned out to be the wave transmitting device, whose power is the lowest. No changes in the visible state of health, organs or cell structure of the subjects were detected.
Interesting! Only a minimal effect on the central nervous system of people was noticed, which can simply be avoided by moving 2-3 meters away from the Wi-Fi electrical device. The devices are almost safe.
Environmental Impact of Wi-Fi
Over the past few years, medical doctors have paid attention to radio waves. A large number of studies and experiments have been carried out, during which it was found that such radiation can affect living organisms. Scientists around the world have sounded the alarm.
The fact is that during thorough research, several negative effects on living organisms have been identified.
- Thermal impact. Electromagnetic radiation permeates our planet right through. Encountering obstacles in the form of living organisms on their way, radio waves try to penetrate through them, causing tissue heating. In large quantities, such radiation can lead to an increase in body temperature and overheating of internal organs.
- Biological effects. Electromagnetic waves can slow down and speed up processes in the body. Such radiation can cause changes in pressure, inhibition of metabolism in living organisms, dulling of reactions and reflexes.

Of course, for a truly destructive impact on the environment, fairly powerful sources of such radiation are needed. A wireless router does not have such power, so it is not capable of radically harming the environment.
conclusions
When used correctly, the harm of wi-fi to humans is minimal. However, prolonged exposure or sleep near emitting devices leads to changes in internal organs. The vessels of the brain, the male and female reproductive system, and the children's body are subject to negative influence.
Accurate data on the health hazards of Wi-Fi router radiation have not been established; detailed research results may appear several decades later. However, it is not recommended to constantly use household appliances that emit waves.
Wi-Fi is harmful to children due to their weaker bodies. Parents are advised to limit their child's wireless use.
Is Wi-Fi harmful to human health?
As already mentioned, electromagnetic radiation can influence living organisms. In the human body, high radio wave radiation can cause some changes:
- increase or decrease in blood pressure;
- change in body temperature;
- dizziness and weakness;
- headache;
- nervousness and irritability;
- drowsiness or, conversely, insomnia;
- poor appetite;
- lethargy and apathy.
The problem of radiation in the apartment becomes especially acute. Due to the fact that the apartments are quite small and the routers are located close to the permanent residence of family members, concerns arise. It is worth noting that in combination with cell phones, microwave ovens, computers and other equipment, routers can not have the best effect on the human body.
A sufficient number of Internet users who have a router at home report fatigue, weakness and dizziness at the end of the day. The negative impact of radio waves on the human body should not be denied.
Many medical workers are inclined to believe that the increasing incidence of brain cancer, Alzheimer's disease and Parkinson's disease is a consequence of the radiation of electromagnetic waves. This has not yet been proven, but research is actively being conducted that will confirm or refute this guess. However, it is better not to wait for this moment, but to think now about preserving your health.
What about the child’s body? Conscientious parents are interested in the problem of the harmfulness of WiFi radiation to the health of children. Many developed countries are actively combating harmful electromagnetic radiation. At home and in school institutions, they try to limit and minimize the harmful effects of radio waves on fragile children's bodies.
Pregnant women
American researchers decided to conduct an experiment and determine the degree of influence of the Wi-Fi signal on pregnant women. Pregnant women were asked to carry a special device that monitors radiation levels throughout the day. The women recorded all their actions and described their condition.
Scientists have collected all the information and come to the conclusion that constant exposure to radiation adversely affects the condition of the woman and the unborn child. The risk of miscarriage increases threefold. Therefore, during pregnancy, it is recommended not to use a mobile phone frequently, not to be constantly near the router, and not to spend a long time in places with strong radiation.
Methods for protecting routers from electromagnetic radiation
Due to the above, the question becomes important: is it possible to protect yourself from Wi-Fi? It is impossible to completely eliminate the harm of electromagnetic waves, since they permeate our entire living space. But there are ways to help make wireless radiation as safe as possible.
- You should not install the router in the place where the family spends the most time. Installing the device in the bedroom is especially contraindicated.
- You should not stay near the router for a long time. Try to install it away from your workplace.
- At night and when you are away from home, turn off your router.
- If your device has a lot of power, try turning it down a little. In this case, you will still have access to the Internet, but the harm to others will be minimal.

If you like to chat on the phone on social networks and instant messengers (Viber, Whats app, VK, Skype), then use a headset during the conversation. This will prevent radiation from your smartphone from affecting your brain. It has long been proven that such a precaution reduces the risk of developing headaches, dizziness, and increased intracranial pressure. As a result, the likelihood of strokes and malignant neoplasms is reduced.
A little light theory
To understand how to behave correctly with these and other wireless devices, here is some general information.
Unlike mobile phones (cell phones), which are located near our body (in our pocket in standby mode and during a call) or near our head during a conversation, routers ( how to set up a wifi router ) or Wi-Fi repeaters ( how to set up a Wi-Fi repeater ) located relatively far from us.
And any non-directional signal is significantly weakened with increasing distance. Without cluttering this article with formulas, we can say that, in addition to distance, frequency also affects the strength of the signal. The higher it is, the more it weakens (attenuates) with distance, the more it is weakened by various obstacles: walls, doors, furniture.
Even a person standing between the router antenna and your smartphone or laptop is an obstacle.
Modern home Wi-Fi routers operate in two frequency ranges: 2.4 GHz and 5 GHz . Old and inexpensive new routers only have the 2.4 GHz band. But a lot of other equipment also works at this frequency: phones, microwave ovens, Bluetooth devices...
An old router that only operates in the 2.4 GHz band
The 5GHz frequency, unlike 2.4 GHz, is less “penetrating”. Solid walls between apartments, floors and ceilings greatly weaken it, and neighbors in most cases “do not see” it. In addition, there is virtually no interference in this range. Therefore, if your devices support this frequency, then it would be wiser to use it.
A dual-band modern router that allows you to select the desired frequency and signal strength
And, if you have a regular budget router operating in the 2.4 GHz band, then you just need to follow certain rules in order to minimize the harm, if it even exists.
Receiving devices (smartphones, laptops, tablets) with a Wi-Fi connection are located at a relative distance from the head, the most important and vulnerable part of our body. The radiation power of a mobile phone during a conversation , which we hold close to our heads, is much higher (up to a hundred times) than wi-fi devices. This is why, by the way, during long conversations, especially with a poor signal, it is recommended to use a headset - wired headphones with a microphone or at least Bluetooth.
The power of electromagnetic radiation decreases in inverse proportion to the square of the distance to the source (the distance has doubled - the intensity of radio frequency radiation has decreased fourfold). That is, moving away from the router, you sharply reduce the signal strength, but your device, which is in your hands or on the table, is forced to increase power in order to fully interact with the router. It's a double-edged sword.
It should also be noted that after the mass introduction of wireless devices, cockroaches suddenly disappeared somewhere - these cute domestic insects, which we had previously fought very persistently and most often to no avail. There were periodic victories when they seemed to go away. But then they returned to delight us again with their nightly runs around the kitchen.
And now, as if by the wave of an electromagnetic wizard’s wand, cockroaches have disappeared from our homes. Only occasionally, in some stores where there is not everything in order with cleanliness, can you find these insects. Coincidence?
If Wi-Fi is so harmless, then why do many people begin to feel unwell in rooms where such devices operate? Or near mobile (cellular) communication towers...
Doctors admit that a certain (very small) percentage of people may have increased sensitivity to various electromagnetic radiation. But this fact has also not been officially proven, but the psychological component here is very significant.
If you are constantly afraid of Wi-Fi radiation (and in severe cases, people begin to fear any electromagnetic radiation), then there will indeed be harm, but not from the “radiation” itself, but from the self-induced state of malaise, headaches, insomnia and other manifestations of the “exposure” router, mobile towers”, etc.
And, if a person can still get rid of his home router and, it would seem, live in peace, then you can’t get away from your neighbors’ ones, if it’s an apartment building. And in any high-rise you can find at least five wifi networks if the apartment is corner and even more if it is in the center of the house. All sorts of phobias begin, character deteriorates, and a person can become truly ill.
Such people should be treated with understanding, explaining how to use such devices correctly and that they do not pose harm to humans.
What is more useful or harmful in a router?
A clear answer to this question has not yet been found. Some argue that wireless connections are much less harmful than televisions and microwaves. Others insist that routers and the Internet are pure evil.
According to reviews from social network users, few people think about whether Wi-Fi is really harmful. It is easier for most people to live with the idea that everything is fine and the manufacturers have taken care of the safety of the population. Only a few want to understand this and begin to look for answers to their question.
According to recent studies, it has become clear that routers do not emit enough radiation to radically harm the human body. Routers are no more dangerous than a TV or tablet. But how many such devices are located within one apartment? If you do the math, the average family of 4 people has at least 1 phone, computer, TV, microwave, tablets or other devices (e-reader, netbook, game consoles). It is likely that all of these devices together have a negative effect on our body.
What to do? Give up all the benefits of civilization for the sake of maintaining health? Or harm yourself for the benefit of technology? The answer, as always, is indecently simple. It is enough to wisely distribute the time you use electronic devices and pay more attention to real life. Try to relax in the fresh air, harden yourself and devote time to physical development. And then no radiation can cause you significant harm.
Male reproductive system
Research in this area has been going on for a long time. Scientists conducted an experiment using thirty healthy men. Sperm was collected from all subjects and the required tests were performed. After the examinations, the containers with sperm were left on the computer near the Wi-Fi router and a large-scale download of files was launched.
At the end of the experiment, four hours later, the sperm was sent for examination again. The result was negative. Under the constant influence of a Wi-Fi signal, twenty-five percent of the sperm died. Almost six percent of surviving samples had serious damage.
There is only one conclusion from such a study: Wi-Fi waves are harmful to the male reproductive system. When conducting experiments with wired information transmission, no changes were noted in the samples.
The Curious Case of Rosie Gladwell
Copied 09/14/2020 09:56:38 from the page https://pronedra.ru/opasen-li-dlya-zdorovya-wi-fi-router-v-kvartire-chto-pokazali-issledovaniya-radiovoln-500657.html - Mozilla /5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.122 Safari/537.36 [2a01:4f8:140:2314::2]
At the beginning of October 2020, media around the world spread information about a certain Rosie Gladwell, who six years ago diagnosed her hypersensitivity to electromagnetic fields caused by Wi-Fi networks.
A 70-year-old UK woman felt weak and unable to breathe when she was near a Wi-Fi network. To take care of her health, Mrs Gladwell spends thousands of British pounds on accessories that (at least in theory) protect her from the wireless network.
One of her most important accessories is a special sleeping bag, which cost her more than £400 and was made of silver and copper. The British woman lives in the forest, she has an additional protective film that she wraps around her body. This is the only way she can survive evenings and long trips away from home. Gladwell said that after just 10 minutes without Wi-Fi, she felt much better.
