But researchers can make some judgments about the potential for harm based on how WiFi and similar technologies work, as well as on how people tend to use their devices. Those factors do provide some reasons to think that WiFi and Bluetooth devices may be less of a concern, says Leeka Kheifets, Ph.D., a professor of epidemiology at the UCLA School of Public Health who has studied the potential health effects of low-level radiation.
The wireless industry has sought to downplay concerns about cell phones’ safety, and the Federal Communications Commission has followed its example. In 1996, the FCC established cell-phone safety levels based on “specific absorption rate,” or SAR. Phones were required to have a SAR of 1.6 watts or less per kilogram of body weight. In 2013, the American Academy of Pediatrics advised the FCC that its guidelines “do not account for the unique vulnerability and use patterns specific to pregnant women and children.” Nevertheless, the FCC has declined to update its standards.30
In 2011, two small studies were published that examined brain glucose metabolism in people after they had used cell phones. The results were inconsistent; whereas one study showed increased glucose metabolism in the region of the brain close to the antenna compared with tissues on the opposite side of the brain (26), the other study (27) found reduced glucose metabolism on the side of the brain where the phone was used.
14. Clean your phone regularly. “Newsflash: Your phone is dirty. Like, really dirty. It’s crawling with germs and bacteria that can cause acne and even nasty rashes. And if you take your phone to the bathroom often, it could also be covered in fecal matter.” – Amanda Hawkins, 5 Ways Your Phone Is Ruining Your Skin, Good Housekeeping; Twitter @goodhousemag
Because of inconsistent findings from epidemiologic studies in humans and the lack of clear data from previous experimental studies in animals, in 1999 the Food and Drug Administration nominated radiofrequency radiation exposure associated with cell phone exposures for study in animal models by the U.S. National Toxicology Program (NTP), an interagency program that coordinates toxicology research and testing across the U.S. Department of Health and Human Services and is headquartered at the National Institute of Environmental Health Sciences, part of NIH.
An analysis of data from NCI's Surveillance, Epidemiology, and End Results (SEER) Program evaluated trends in cancer incidence in the United States. This analysis found no increase in the incidence of brain or other central nervous system cancers between 1992 and 2006, despite the dramatic increase in cell phone use in this country during that time (22).
After years of warnings, we are fairly used to ensuring we have anti-spyware, anti-malware, and anti-virus programs on our computers. This software should also be used on our smartphones as well. Search for programs in the app stores and discuss them with your wireless provider. Some phones come with built-in software that you won’t want to override.

With that in mind, several school districts in the U.S. and other countries have tried to reduce exposure in the classroom to RF radiation from devices. The Maryland State Department of Education, for example, recommended in 2016 that school districts use wired networks instead of WiFi whenever possible, turn off routers when not being used, and keep routers as far away from students as possible. In France, WiFi is banned from nursery schools.
Acute exposure of rabbits to WIFI increased heart frequency (+22%) and arterial blood pressure (+14%). Moreover, analysis of ECG revealed that WIFI induced a combined increase of PR and QT intervals. By contrast, the same exposure failed to alter maximum amplitude and P waves. After intravenously injection of dopamine (0.50 ml/kg) and epinephrine (0.50 ml/kg) under acute exposure to RF we found that, WIFI alter catecholamines (dopamine, epinephrine) action on heart variability and blood pressure compared to control. 
There are few if any references to actual studies in published, peer-reviewed journals that support the claim that Aires, or any other, cell phone shield actually works. The "Researches" page contains a superficially impressive list of sciencey-sounding titles and findings supposedly demonstrating the importance of using cell phone shields, all of them in Russia for some reason.
Years later, a study that Leszczynski described as a “game changer” discovered that even phones meeting government standards, which in Europe were a SAR of 2.0 watts per kilogram, could deliver exponentially higher peak radiation levels to certain skin and blood cells. (SAR levels reached a staggering 40 watts per kilogram—20 times higher than officially permitted.) In other words, the official safety levels masked dramatically higher exposures in hot spots, but industry-funded scientists obstructed research on the health impacts.45
“So what can you do? Straighten up, first of all, says Kenneth Hansraj, M.D., an orthopedic surgeon in Poughkeepsie, New York. And carry device at chest height with head up, chest open and shoulder blades back. Move just your eyes downward. And then, take a break. Your neck is not supposed to stay stuck in one position for a long period. If you’re reading on a tablet or phone, stop every so often to swivel and tilt your head — up and down, then side to side.” – 3 Dumb Things We Do with Smartphones, Good Housekeeping; Twitter: @goodhousemag
My son likes to listen to music when he sleeps. He subscribes to Spotify, and has his playlists downloaded to his phone. He now uses airplane mode at night & uses Spotify this way–but of course he sleeps w/ his phone. (He also sleeps in a basement.) Is this still dangerous? If so, what do you suggest he do to be able to listen to continuous music safely at night? He is 21 and resistant to put down the phone… but he does listen, esp. if others (esp non-Mom others!), particularly “professionals” give solid researched reasons. I am going to print this article and share it with him. (My other 3 teenagers don’t have an issue and several don’t even have a phone… but he’s my firstborn, and more into the phone…)

“Everyone knows that if your research results show that radiation has effects, the funding flow dries up,” Leszczynski said in an interview in 2011. Sure enough, the Radiation and Nuclear Safety Authority of Finland, where Leszczynski had a long career, discontinued research on the biological effects of cell phones and discharged him a year later.46

Wheeler’s tactics succeeded in dousing the controversy. Although Carlo had in fact repeatedly briefed Wheeler and other senior industry officials on the studies, which had indeed undergone peer review and would soon be published, reporters on the technology beat accepted Wheeler’s discrediting of Carlo and the WTR’s findings. (Wheeler would go on to chair the Federal Communications Commission, which regulates the wireless industry. He agreed to an interview for this article but then put all of his remarks off the record, with one exception: his statement that he has always taken scientific guidance from the US Food and Drug Administration, which, he said, “has concluded, ‘the weight of scientific evidence had not linked cell phones with any health problems.’”)11

31. Read the fine print. “Buried in cell phone manuals, cell phone companies specifically instruct us that phones should not be held close to the body. For example, the iPhone 5 manual states “Carry iPhone at least 10mm away from your body to ensure exposure levels remain at or below the as—tested levels. Cases with metal parts may change the RF performance of the device, including its compliance with RF exposure guidelines, in a manner that has not been tested or certified.” The Blackberry Bold states, “keep the BlackBerry device at least 0.59 in. (15 mm) from your body (including the abdomen of pregnant women and the lower abdomen of teenagers) when the BlackBerry device is turned on and connected to the wireless network.
Most wireless LAN equipment is designed to work within predefined standards. Wireless access points are also often close to humans, but the drop off in power over distance is fast, following the inverse-square law.[9] However, wireless laptops are typically used close to humans. WiFi had been anecdotally linked to electromagnetic hypersensitivity[10] but research into electromagnetic hypersensitivity has found no systematic evidence supporting claims made by sufferers.[11][12]
