Excessive contact with the radiation emitted by mobile phones, laptops and tablets could be dangerous to the human body. Should we turn off the router when not in use? Is it better to “hands-free” cell? How far we stand from the computer? Advice of specialists in the field to prevent overexposure to Wi-Fi.
For the Spanish Joan Carles López, an expert in radiation Geobiology and habitat, it is not resist using new technologies, but to use “common sense”.So it is asking people to take “awareness” and then “Electric hygiene.”
But is there a real basis for asserting that wireless devices are harmful to human health? The World Health Organization (WHO) argues that the main consequence of the interaction between radio frequency energy and the human body is the heating of tissues. In the case of the frequencies used by mobile phones, most of the energy is absorbed by the skin and other superficial tissues, so that the temperature rise in the brain or other organs is negligible.
So the Wi-Fi is harmful or not?
“Exposure to radiation from Wi-Fi is highest since the computer from the router,” argues Elisabeth Cardis, head of the “Centre for Research in Environmental Epidemiology” (CREAL) in Catalonia, Spain. After several investigations concluded that “if the RF source is not attached to the head, the exposure level is very low.” Luckily, the computer or one meter 60 centimeters inside the body.
CREAL performed “Interphone” one of the most important studies that were conducted on the subject. It was attended by 13 countries, and as a result some evidence to show that those with more cumulative hours of cell phone use might be more likely to develop a rare brain tumor called glioma were found.
On the other hand, patients who participated in the investigation began to use mobile phones at a later age than young people today, if you consider that a cancer or tumor can take years to manifest. For this reason the WHO considers that it is still nothing said about whether it is dangerous or not, and that should deepen research in specific population groups such as children and adolescents.
To avoid risks, take some precautions:
* Zoom the head phone and using “hands-free” to talk or send text messages.
* Using lift x o que é.
* Place the access point Wi-Fi at least one meter away from places where people often stay longer as beds, tables, sofas or playgrounds.
* The transfer of large data files or “streaming media” should only be performed when the connection is established between the portable device and the access point in a room it is of good quality to avoid retransmissions, leading to cycles of higher labor and the largest exposures.
* In places where Wi-Fi is often used, coverage should be good enough.
* Access points must be turned off when not in use, because even when not using Wi-Fi, the device transmits beacon signals on every 102 meters.
* In public spaces it is preferable to install a single Wi-Fi network coverage to all teams back to the old system or cable Internet.
