Is the radiation from the wifi router harmful?
A router, 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 a wire connection means the transmission of information through electromagnetic radiation. Because the routers are operating at ultra-high frequencies, the question is quite legitimate: is the radiation from the wifi router harmful? The results of some studies refute these fears, others confirm. Consider the arguments of both sides.
Why radiation from a wifi router can be dangerous
Descriptive argumentation is not as significant as the exact technical characteristics of the device in question. Therefore, let us turn to the figures. Wifi router operates in the frequency range of 2.4 GHz, and the power of ordinary routers is ~ 100 μW. When this frequency is applied to the cells of the human body, the molecules of water, fat and glucose converge and rub, 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 influences on this range from wireless LANs can make dysfunction in the process of cell growth and division.
The damage to wifi radiation is aggravated by the radius and speed of data transmission. An excellent illustration to this fact is the enormous speed of transmission of a large array of information when downloading videos, photographs and other data. The transmitting medium is air, and the carrier frequency is the mid-wave frequency range. And, since our cells are able to transmit and receive energy at different frequencies, the negative effect of the frequency range of the router is entirely acceptable.
Residents of apartment buildings may experience the impact of many routers installed in neighboring apartments. Brick walls and metal structures only partially reduce the range of the router, but do not delay its radiation completely. Add to this wireless access points to the Internet in offices, shopping centers, cafes. It becomes clear that a person is under the influence of a wifi router's radiation almost around the clock.
Especially since 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. Maybe that's why even a night's sleep does not bring many a full recovery, and the immune system does not protect us from a lot of infections and viruses.
Is it really harmful wifi router
Of course, for the convenience of wireless Internet use you have to pay. 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, called the absolute optical power of radiation, was introduced. The unit of its measurement is 1 decibel-milliwatt (dBm). The average mobile phone power is 27 dBm, while the same value for the router is 20 dBm.
Further, the router is never located at such a close distance as the mobile phone. Usually it is 1-2 meters. We 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 the radiation from a wifi router
If somewhere in the subconscious there is still an alarm due to this radiation, you can try to reduce the radiation of the router. Each of the devices of this designation provides for signal power adjustment. Few people pay attention to this function, and virtually routers from all users, while retaining factory settings, are turned on at full capacity. By setting the transmitter power to 50, 25% or even 10%, it is possible to significantly reduce the radiation dose and the coverage area.
And, having followed this operation from neighbors, it is possible to reduce the level of irradiation tens and hundreds of times. Moreover, manufacturers to increase the number of sales often unreasonably overestimate the power of these devices.
Can I protect myself from the radiation of the router? Of course, the radiation of the router affects the person. But how great is the harm of Wi-fi radiation, there is no definitive answer yet.
But there are such figures:
- the signal strength of the Wi-Fi router is 100 000 times weaker than that of the microwave oven;
- the radiation from two routers and twenty laptops is equivalent to the impact from one mobile phone.
If these impressive comparisons did not reassure the most skeptical skeptic, the following simple rules will prompt you how to protect yourself from wifi radiation:
- install routers at a distance of at least 40 cm from their workplace and certainly not to sleep next to the included router;
- disable your access point if you do not intend to use the Internet;
- do not hold the laptop on your lap.
Technologies for protection against electromagnetic smog
The background created by various sources of electromagnetic radiation is called electromagnetic smog. Naturally, attempts are being made to protect themselves immediately from all these pathological influences.
- Enterprising manufacturers have established the production of wallpaper, capable of screening Wi-Fi radiation emanating from neighboring apartments. You can buy them through foreign online stores. However, this particular product will interfere with the transfer of the Internet to other rooms within the apartment.
- The health product market has a new product - the corrector of the functional state of the body (CFS). Among a wide range of products for this purpose, a fabric cover with a carbon thread is offered. The material for creating such covers is a special bipolar fabric that can reflect electromagnetic radiation from computers, wifi routers, telephones and other household appliances.
Let's sum up - the above information is based on 4 parameters, allowing to give an objective assessment of whether the Wi-Fi router is harmful to health:
Each of them works in favor of the theory of its negative impact.
And, although to date there are no real facts that can confirm that it was the wifi networks that caused the disease, compliance with security measures will be far from superfluous. Moreover, as long as humanity does not have data on the effect of microwave radiation on the next generation.
