The life of a modern person is unthinkable without information technology. The desire to always and everywhere stay up to date with unlimited access to information explains the frenzied popularity of the Wi-Fi network. Almost every family on the planet uses this miracle of technology. But a reasonable question arises: how safe is this invention for users? The answer will help find this article.
What is Wi-Fi?
Translated from English, this abbreviation refers to high-precision wireless data transmission (Wireless Fidelity). The principle of operation of this phenomenon is based on the ability of certain radio waves to transmit information from one device to another. To do this, you just need to acquire a broadcasting device - a router and a receiver - a smartphone, tablet or computer.
Why is the wifi signal harmful?
Numerous studies have proved that the radio waves to which the described phenomenon belongs can adversely affect the state of living things. In general, two main exposure options can be distinguished:
- changes in body temperature and internal organs. Wave radiation penetrates the planet through and easily passes through living organisms, causing involuntary heating of tissues;
- influence on the course of processes in the body. Acceleration or deceleration of metabolism, failure in the manifestation of reflexes adversely affects the functioning of vital systems.
But, in addition to scientific research, the WiFi phenomenon, which has not been fully studied, is overgrown with all kinds of guesses.
The most popular Wi-Fi myths
Viruses infect devices via WiFi
Wi-Fi is just one way to transmit information. Along with the usual connection via a network cable, it only provides access to the Internet. And the appearance of malware arises when viewing questionable content or downloading unreliable software.
The radiation from the router has a high power
Residents tend to compare the degree of harm Wi-Fi with household appliances and smartphones. Mobile phones operate at a power of 1 W, while the power of a Wi-Fi device, even at a maximum frequency, does not exceed 100 mW. Therefore, we can safely talk about the lesser impact of WiFi compared to smartphones and other gadgets.
Reference! Wi-Fi router and microwave work at the same frequency. But the radiation of a household appliance is 100 times higher than that of a network device.
Speculation is speculation, but the concerns of the townsfolk have a basis.
Consequences of Using WiFi
Many active users of the network note a deterioration in health at the end of the day. A headache appears, minor changes in arterial and intracranial pressure occur. Some scientists trace the connection between the increasing incidence of Alzheimer's, Parkinson's and brain cancer and the widespread use of electromagnetic waves. This hypothesis has not yet been proven. But there are already some conclusions about the effect of radiation on human health.
Important! Wi-fi itself is not as harmful as the long-term use of mobile devices operating on a wireless network.
Official opinions of doctors and scientists
At the moment, scientists can not answer unambiguously whether Wi-Fi is safe for humans.
So,Head of the Ministry of Health of England William Stewart says that minor radio waves affect the human body. But this radiation is 600 times lower than the permissible norm.
Some scientists do not undertake to give categorical estimates, because the technology itself has come into use recently.
Doctor of Medical Sciences David Backsteindoes not link cancer formation using modern devices. But he notes that "much more time is needed to study their effect on the body«.
Other representatives of medicine, among whichradiation hygiene doctor Tatyana Vasilieva and therapist of the highest category Nadezhda Koloskova,indicate the indirect effect of electromagnetic radiation on the physical condition of a person. Prolonged interaction with a mobile phone or computer deprives the user of the opportunity to spend time outdoors and breathe fresh air.
In general, doctors agree that the effect of Wi-Fi can only be assessed after a decade of observation. But many scientists are already convinced that close contact with mobile phones and laptops does significant harm. Putting a cell phone in a trouser pocket or placing a PC on your lap, the user risks making reproductive problems and even infertility.
How to reduce the health effects of radiation
No matter how minimal the effect of wireless data transmission on our body, it still exists. To protect yourself and your loved ones from the possible consequences of radio emission, it is enough to adhere to the following rules:
- place the router in the room where family members are least likely to be (for example, in the hallway) and in no case install it in the bedroom;
- disconnect Wi-Fi connection at night and during a long absence;
- reduce the power of signal reception on your device. This will not lead to loss of Internet access, but will make it less harmful to others;
- use the headset for conversations through the WhatsApp, Viber, VK and Skype messengers. Headphones will save the user from headaches and poor health.
The use of gadgets and Wireless Fidelity technology have made modern life convenient and interesting. With the right attitude to the benefits of civilization, no negative consequences for human health are terrible.
