The use of Wi-fi has increased rapidly in recent years. Through the use of this technology, electronic devices are connected to a computer network wirelessly using radio waves, or radiofrequency (RF) electromagnetic energy (EME), thereby eliminating or reducing the need for network cables. A common example is a laptop connected to the internet using a wi-fi modem at home. Wi-fi access points can also be found in schools and many public areas. People in a wi-fi enabled environment will be exposed to low level RF EME from time to time when using the network on computers and also from the access points. There is some public concern about potential health effects associated with RF EME emissions from wi-fi in homes, schools and other places.

10. Your house may be burglarized due to social media. “If you spend any time with social media, (Facebook, Twitter, etc.) You have probably found that you can “check-in” somewhere to let all your friends know what you’re up to, and maybe even stop by for coffee. But if your security settings on the social networks are not set properly, you could just as easily be telling robbers that your house is vacant right now, which they will find most helpful when they clean you out. Sometimes, they will come back in a couple of months, to get this stuff you bought with the insurance money, too. Occasionally, they will look for important documents to commit identity theft. All told, checking-in may be one of the most reckless cell phone safety errors we can commit.” – Cell Phone Safety Identity Theft and Cell Phone Security, About Money; Twitter: @AboutMoney

Belgium recently adopted new cell phone regulations that bar mobile phone models designed for, and marketed to children ages 7 and younger.  Under Belgium’s new rules, slated to take effect next March, cell phone retailers will be required to disclose phones’ maximum emission levels, known as specific absorption rates, or SAR, at the point of sale.  Belgium becomes the latest in a rapidly lengthening list of nations to attempt to shield children from too much cell phone radiation and to inform everyone about the risks of exposure to these emissions. At least a dozen other nations have taken steps to protect children from cell phone radiation.

RESULTS: Our analysis demonstrates that the data from a substantial amount of the studies on RF-EMFs from mobile phones show physiological and/or morphological effects (89.9%, p < 0.001). Additionally, our analysis of the results from these reported studies demonstrates that the maize, roselle, pea, fenugreek, duckweeds, tomato, onions and mungbean plants seem to be very sensitive to RF-EMFs. Our findings also suggest that plants seem to be more responsive to certain frequencies, especially the frequencies between (i) 800 and 1500 MHz (p < 0.0001), (ii) 1500 and 2400 MHz (p < 0.0001) and (iii) 3500 and 8000 MHz (p = 0.0161).

Of course, trying to avoid radio wave exposure is more or less impossible if you live in modern society. Moskowitz advises keeping wireless devices away from your body and turning off wireless networks when they’re not in use. While any health risks are still theoretical, “I think trying to minimize exposure is the best advice at this point,” Moskowitz adds.

MATERIALS AND METHODS: Adult male Sprague-Dawley rats in the weight range of 230 to 260 g were divided into control, sham, Wi-Fi exposed groups. After long term exposure (4 h/day for 45 days) to Wi-Fi electromagnetic radiation, plasma levels of glucose and insulin during intraperitoneal glucose tolerance test were measured. Islet insulin secretion and content, lipid peroxidation and antioxidant status in pancreas of rats were determined.
The aim of the present study was to investigate oxidative stress and apoptosis in kidney tissues of male Wistar rats that pre- and postnatally exposed to 2.45 GHz wireless electromagnetic field (EMF) for 1 h/day until puberty. Based on this study, it is thought that chronic pre- and post-natal period exposure to wireless internet frequency of EMF may cause chronic kidney damages; staying away from EMF source in especially pregnancy and early childhood period may reduce negative effects of exposure on kidney.

Like their tobacco and fossil-fuel brethren, wireless executives have chosen not to publicize what their own scientists have said about the risks of their products. On the contrary, the industry—in America, Europe, and Asia—has spent untold millions of dollars in the past 25 years proclaiming that science is on its side, that the critics are quacks, and that consumers have nothing to fear. This, even as the industry has worked behind the scenes—again like its Big Tobacco counterpart—to deliberately addict its customers. Just as cigarette companies added nicotine to hook smokers, so have wireless companies designed cell phones to deliver a jolt of dopamine with each swipe of the screen.19
We do have evidence that cellphones (or WiFi) do NOT cause an increase in brain tumors. Look at the time period over which cellphone use became common -- say, over the last twenty years. During that time, the incidence of brain tumors has remained absolutely flat. With over four billion people using cellphones (or WiFi) today, if there was any influence on the development of brain tumors, we would be seeing that by now.

High frequency, specifically 2.45 GHz Wi-Fi radiation, induces a decrease in sperm parameters along with an increase in apoptosis-positive cells and caspase-3 activity in the seminiferous tubules of Wistar rats, specially in 7-hour group. It reduced seminal vesicle weight following 2.45 GHz exposure. Considering the progressive privilege of 2.45 GHz wireless networks in our environment, we concluded that there should be a major concern about the time-dependent exposure of our body to the higher frequencies of Wi-Fi antenna.

MATERIALS AND METHODS: The study was carried out on 16 Wistar Albino adult male rats by dividing them into two groups such as sham (n = 8) and exposure (n = 8). Rats in the exposure group were exposed to 2.4 GHz radiofrequency (RF) radiation for 24 hours a day for 12 months (one year). The same procedure was applied to the rats in the sham group except the Wi-Fi system was turned off. Immediately after the last exposure, rats were sacrificed and their brains were removed. miR-9-5p, miR-29a-3p, miR-106b-5p, miR-107, miR-125a-3p in brain were investigated in detail.
The environmental exposure to RF radiation in some schools is higher than reported levels for non-thermal biological effects. In order to reduce children’s exposure to RF radiation, schools should prefer wired network connections, allow laptop, tablets, and mobile phone usage only in flight mode and deactivate Wi-Fi access points when internet is not needed for learning purposes.
The most compelling evidence though comes from a Swedish team of cancer experts whose research stretches back 15 years. The results clearly demonstrate “a consistent association between long-term use of cell phone and cordless phones and glioma and acoustic neuroma”. Overall, they found that using a cell phone for more than a decade significantly increases the risk of a malignant tumour by almost two times with an analogue cell phone and by nearly four times with a digital phone. Interestingly, the risks were even higher for people who had started using mobiles as teenagers.
