Impact wifi for humans

Wi-fi (wireless fidelity), better known as the local wireless network is increasingly popular, especially in the developed countries and developing countries. With wi-fi people can go to the Internet without the hassle of connecting the cable from the computer to the phone line. It is nice yes if we stay in area existing wi-fi, but quizzed had inquired siyal wi-fi affecting the body. Want to know?Behind the convenience offered wi-fi, there are some beliefs that consider public wi-fi have a negative impact on health. Those who do not agree with the presence of wi-fi high grounds electromagnetic radiation from wi-fi can cause pain in the head, sleep disturbance and nausea, especially for those who electrosensitive. But is wi-fi is harmful to health?

Fear of adverse effects on the health of the wi-fi was denied by British scientists. As expressed by Sir William Stewart, chairman of the Health Protection Agency, told BBC Panorama Programme, there's nothing to worry about with wi-fi technology. There is no compelling evidence to say, devices such as cell phones and wi-fi cause impaired health. 

The same thing also expressed Professor Lawrie Challis, of Nottingham University. In a statement to the BBC, Monday (21/05), Prof Challis, who served as chairman of the Mobile Telecommunications and Health Research (MTHR) said: "electro-magnetic radiation from Wi-fi is very small, low-power transmitter as well, but it was still some distance with the body. 

"It could be electro magnetic radiation is very close to the body, when we are assuming the laptop, but in my pengamaatan every parent will ask their children not to overuse their phones and always ask them to put the laptop on the table, not on your lap, if they surf too long. " 

To support this statement, the BBC Panorama team visited a school in Norwich, which has a thousand students, and try to compare the levels of radiation from mobile phones and the use of wi-fi in the classroom. The results showed radiation wi-fi in the classroom three times larger than the jet issued cell phone.

But mental health expert Professor Malcolm Sperrin said wi-fi signal greater than three times the radiation of a cell phone at school is still relevant, and there are no effects on health. "Wi-Fi is a technology that uses radio frequency electro-magnetic low, which is comparable to a microwave oven, even 100 thousand times lower than the microwave." This type of radiation emitted by radio waves (wi-fi), microwaves, and cell phones have shown increases in the level of networks of very high temperatures, the so-called thermal interaction, but there is still no evidence of the level is causing the damage. Health Protection Agency said sitting in a room that has a hotspot for a year comparable to the radio waves emitted when conversing with the phone for twenty minutes. "Radio waves have become a part of our lives for nearly a century or more, but if there is a significant disruption to health, there must be a study that will record it, and so far studies have found no evidence of transmission of wi-fi for health. The same thing is also supported by Professor Will J Stewart, a fellow of the Royal Academy of Engineering, who said: "Science pengetahunan have studied the effect of mobile phones for health for years and concerns about the impact of cell phone radiation is still very small. 

"So is the wi-fi, if used within reasonable limits there would be no effect on health in a long time. But that does not mean that all electromagnetic radiation is harmless, such as sunlight proven to cause skin cancer, so if you are using a laptop while lying on the beach, it's good to look for a shady place, "added the Sperrin said until now there is still no sufficient evidence berrarti negative impact wi-fi. 

But more worried Sperrin not on wi-fi waves, but the behavior in the use of laptops and laptop heat generated in some sensitive parts of the body, which affect health.
