We investigated the long-term effects of radiofrequency radiation (RFR) emitted from Wi-Fi systems on hearing. Sixteen Wistar albino rats were divided equally into two groups: sham control and exposure groups. The rats in the experimental group were exposed to 2.4 GHz RFR emitted from a Wi-Fi generator for 24 h/day for one year. The same procedure was applied to the rats in the sham group, except that the Wi-Fi generator was turned off. All groups were kept in Faraday cages during the 12 months to eliminate external electromagnetic fields. The distance between the Wi-Fi generator antenna and the exposure cages was 50 cm. Pre-exposure distortion product otoacoustic emissions (DPOAE) of all rats were measured at the beginning, 6th and 12th months of the study. The DPOAE values of the sham, baseline and exposure groups were compared statistically. For the 6000 Hz hearing frequency, the DPOAE values in the exposure group were lower than those in the sham group (p < 0.05). Similarly, the 6000 Hz hearing frequency values obtained at the end of the 12th month were also lower than the baseline and 6-month values in the exposure group (p < 0.05). In contrast, the DPOAE values at the 6th and 12th months of exposure for the 2000 Hz hearing frequency were higher than the baseline value (p < 0.05). These results indicated that 12 months of RFR (24 h/day) at 50 cm from a 2.4 GHz Wi-Fi source can affect hearing. However, further studies are necessary.
Carlo’s story underscores the need for caution, however, particularly since it evokes eerie parallels with two of the most notorious cases of corporate deception on record: the campaigns by the tobacco and fossil-fuel industries to obscure the dangers of smoking and climate change, respectively. Just as tobacco executives were privately told by their own scientists (in the 1960s) that smoking was deadly, and fossil-fuel executives were privately told by their own scientists (in the 1980s) that burning oil, gas, and coal would cause a “catastrophic” temperature rise, so Carlo’s testimony reveals that wireless executives were privately told by their own scientists (in the 1990s) that cell phones could cause cancer and genetic damage.17

So of course now that we understand that the cases are not tested and just the material--it makes sense! We measured power density levels all around the case-the shielding material most likely isn't used "all over" because then the phone couldn't receive signal and wouldn't be able to engage in a call.  That's why we did not see even close to a 99% reduction when some cases were on the phone.  In fact, watch the video and you'll see some readings are more than 20% higher with a case on vs the naked phone.

Anything you can do to keep the phone away from your head will help. (Even cell phone manufacturers warn consumers about this. See the previous post Cell Phone Manual Warnings for examples of warnings from Samsung, Apple and more.) If you hold the phone 2 inches away, the signal is about one-fourth the original strength. At four inches away, it’s about 1/16th as strong. Even better is a hands-free kit with a wireless air tube nearest the earpiece. (A regular wired headset can act as an antenna and make matters worse.)

The increasing use of Wi-Fi in schools and other places has given rise to public concern that the radiofrequency (RF) electromagnetic fields from Wi-Fi have the potential to adversely affect children. The current study measured typical and peak RF levels from Wi-Fi and other sources in 23 schools in Australia. All of the RF measurements were much lower than the reference levels recommended by international guidelines for protection against established health effects. The typical and peak RF levels from Wi-Fi in locations occupied by children in the classroom were of the order of 10-4 and 10-2% of the exposure guidelines, respectively. Typical RF levels in the classroom were similar between Wi-Fi and radio but higher than other sources. In the schoolyard typical RF levels were higher for radio, TV and mobile phone base stations compared to Wi-Fi. The results of this study showed that the typical RF exposure of children from Wi-Fi at school is very low and comparable or lower to other sources in the environment.
Unfortunately, the current state of cell phone radiation research is similar to the early days of tobacco research. It wasn't until 1999 when the U.S. Department of Justice finally filed a racketeering lawsuit against the major tobacco companies for engaging in a "50 year scheme" to counteract any scientific evidence that showed that cigarettes are harmful to a person's health. Is the potential cell phone cancer link the same sort of scenario? Are cell phone companies funding and promoting research that "proves" no link from cell phone radio radiation in an effort to discredit those studies that are uncovering problems?
This study aimed to investigate the effect of 2.4 GHz Wi-Fi radiation (12 h/day for 30 days) on multisensory integration in male rats. Results demonstrated that rats in Wi-Fi exposure groups could not discriminate significantly between the novel and familiar objects in any of the standard SOR, tactile SOR, visual SOR, and CMOR tests and the expression of M1 receptors increased following Wi-Fi exposure. In conclusion, results of this study showed that chronic exposure to Wi-Fi electromagnetic waves might impair both unimodal and cross-modal encoding of information.

Turkish Telecommunication and Information Technology Agency declared that the daily usage of internet is nearly 6 hours in Turkey [15]. Therefore, according to us, Wi-Fi usage needs to get more attention than cell phone usage due to its higher frequency ranges and longer exposure times [16]. Even though there are some studies performed on the effects of  RF-EMR and cell phones on male fertility, there is not so much scientific data about the association between Wi-Fi internet usage and male fertility [17]. Unlike other RF-EMR sources, devices such as laptops and tablets usually stay near the reproductive organs.

Mobile phones and Wi-Fi radiofrequency radiation are among the main sources of the exposure of the general population to radiofrequency electromagnetic fields (RF-EMF). Previous studies have shown that exposure of microorganisms to RF-EMFs can be associated with a wide spectrum of changes ranged from the modified bacterial growth to the alterations of the pattern of antibiotic resistance. Our laboratory at the nonionizing department of the Ionizing and Non-ionizing Radiation Protection Research Center has performed experiments on the health effects of exposure to animal models and humans to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile phone jammers, laptop computers, radars, dentistry cavitrons, magnetic resonance imaging, and Helmholtz coils. On the other hand, we have previously studied different aspects of the challenging issue of the ionizing or nonionizing radiation-induced alterations in the susceptibility of microorganisms to antibiotics. In this study, we assessed if the exposure to 900 MHz GSM mobile phone radiation and 2.4 GHz radiofrequency radiation emitted from common Wi-Fi routers alters the susceptibility of microorganisms to different antibiotics. The pure cultures of Listeria monocytogenes and Escherichia coli were exposed to RF-EMFs generated either by a GSM 900 MHz mobile phone simulator and a common 2.4 GHz Wi-Fi router. It is also shown that exposure to RF-EMFs within a narrow level of irradiation (an exposure window) makes microorganisms resistant to antibiotics. This adaptive phenomenon and its potential threats to human health should be further investigated in future experiments. Altogether, the findings of this study showed that exposure to Wi-Fi and RF simulator radiation can significantly alter the inhibition zone diameters and growth rate for L monocytogenes and E coli. These findings may have implications for the management of serious infectious diseases.
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.
In conclusion, although EMR exposure decreased the prolactin, estrogen, and progesterone levels in the plasma of maternal rats and their offspring, EMR-induced oxidative stress in the uteri of maternal rats increased during the development of offspring. Mobile phone- and Wi-Fi-induced EMR may be one cause of increased oxidative uterine injury in growing rats and decreased hormone levels in maternal rats. TRPV1 cation channels are the possible molecular pathways responsible for changes in the hormone, oxidative stress, and body temperature levels in the uterus of maternal rats following a year-long exposure to electromagnetic radiation exposure from mobile phones and Wi-Fi devices. It is likely that TRPV1-mediated Ca2+ entry in the uterus of pregnant rats involves accumulation of oxidative stress and opening of mitochondrial membrane pores that consequently leads to mitochondrial dysfunction, substantial swelling of the mitochondria with rupture of the outer membrane and release of oxidants such as superoxide (O2 -) and hydrogen peroxide (H2O2). The superoxide radical is converted to H2O2 by superoxide dismutase (SOD) enzyme. Glutathione peroxidase (GSH-Px) is an important antioxidant enzyme for removing lipid hydroperoxides and hydrogen peroxide and it catalyzes the reduction of H2O2 to water.

i say to be as proactive as possible, limited wifi use and all of the above, but we can’t live in bubbles and if all this powerful God given food, supplements, exercise and sunshine is so good for us… then focus on that more than anything. stress of all the unknowns will kill us faster if we obsess about it. live like God wants you to, laugh a lot and stop worrying.
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
Numerous peer-reviewed studies have found that cell phone use is not associated with an increased risk of brain tumors. An Oct. 20, 2011 study of 358,403 Danish citizens – the largest study of its kind to date – concluded that "there was no association between tumors of the central nervous system or brain and long term (10 years +) use of mobile phones." [39] A July 27, 2011 study found that there was no association between cell phone use and brain tumor risks among children and adolescents. [50] Numerous other studies published from 2001-2013 have similarly concluded that there is no association between cell phone use and the development of brain tumors. [1] [41] [42] [45] [46] [49]
The purpose of the study was to investigate the effect of 2.45 GHz microwave radiation (2 h/day for 35 days) on the male rat brain. MWR-exposed rats showed significantly increased comet head, tail length and tail movement, as well as decrease of antioxidant enzymes. Researchers conclude that the chronic exposure to these radiations may cause significant damage to brain, which may be an indication of possible tumour promotion.
The king is dead — long live the king. If you’re looking for a smartphone that doesn’t break the bank and won’t sting too much if it’s lost, but still offers good performance, then Motorola’s G-range is usually where you’d start. This year, the Moto G6 has upped the ante, delivering a glass-and-metal design that your sprog won’t be ashamed to be seen with. A protective case is included in the package, but you might want to pick from our range of the best Moto G6 cases, since glass is prone to breaking.
Members of the public often ask about the cumulative exposure that a child receives when using a Wi-Fi device in a classroom in which a number of children are simultaneously using Wi-Fi. When downloading files, most of the transmissions will be from the access point, not the students’ device. When downloading and uploading only a portion of the maximum capacity of a network would be used even in a classroom filled with children using Wi-Fi. The Wi-Fi network divides RF transmissions among the access points and client devices therefore the individual RF exposure to a child in a classroom that is using a device consists of sequential exposures from all active devices, the majority of which are located at some distance away(15). For the majority of schools (20) the measurements in the current study were conducted in an empty classroom (to avoid lesson disruption) with an access point and one laptop. In three schools, measurements were conducted with students or teachers present and using Wi-Fi devices. A comparison between measurements conducted in empty classrooms and classrooms with multiple students/teachers using Wi-Fi showed no significant difference in the RF levels (p > 0.1 for all); although this may have been due to low numbers (only three schools measured with multiple users in the classroom).
These articles and websites don’t exist because the threat is real, however. They exist because they are a vehicle for turning people’s fear into money. The more people share nonsense articles about the dangers of Wi-Fi (or other harmless modern things) the more people click on them, the more ad-revenue is generated, and the more motivation the people peddling these rubbish articles have to keep creating and promoting them.

Radiofrequency radiation is a form of electromagnetic radiation. Electromagnetic radiation can be categorized into two types: ionizing (e.g., x-rays, radon, and cosmic rays) and non-ionizing (e.g., radiofrequency and extremely low frequency, or power frequency). Electromagnetic radiation is defined according to its wavelength and frequency, which is the number of cycles of a wave that pass a reference point per second. Electromagnetic frequencies are described in units called hertz (Hz).
These studies are not definitive. Much more research is needed. But they raise serious questions that cast doubt on the adequacy of the FCC rules to safeguard public health. The FCC emissions cap allows 20 times more radiation to reach the head than the body as a whole, does not account for risks to children’s developing brains and smaller bodies and considers only short-term cell phone use, not frequent calling patterns over decades.

Conclusions: Based on the extensive body of research and the adverse health effects demonstrated in the majority of the studies, it is recommended that steps should be taken to minimize RF radiation exposure in accordance with official recommendations. Wired solutions should be given preference. Current exposure limits and SAR values do not protect from health risks associated with Wi-Fi radiation. The adverse effects on learning, attention, and behavior serve as a basis for educational institutions of all age groups to forgo the use of Wi-Fi applications. Due to cytotoxic effects, Wi-Fi technologies are not suitable for hospitals and telemedicine. Wi-Fi technologies should not be used in bedrooms, work spaces, common lounges, hospital rooms, lecture halls, classrooms, and public transport. The possible risks associated with Wi-Fi radiation could be avoided by testing alternative technologies at other frequency bands like optical VLC/Li-Fi technologies (visible light communication). When Wi-Fi cannot be avoided as a transition solution, the ALARA principle must be applied: no continuous transmission, instead Wi-Fi networks that can be turned off and feature dynamic power management.

This study was aimed at investigating the alteration of antibiotic resistance of Klebsiella pneumonia, after exposure to Wi-Fi 2.4 GHz electromagnetic radiofrequency radiation from a Wi-Fi router for 3, 4.5 or 8 hours. The findings of this study show a statistically significant rise in the sensitivity of Klebsiella pneumoniae to different antibiotics after 4.5 hours of exposure to 2.4 GHz Wi-Fi radiation, followed by a fall after 8 hours of exposure. These observations can be interpreted by the concept of non-linearity in the responses of Klebsiella pneumoniae to different antibiotics after exposure to electromagnetic radiofrequency radiation.
This study analyzed cellular stress levels in rat thymus after exposure to a 2.45 GHz radio frequency (RF) using an experimental diathermic model in a Gigahertz Transverse Electromagnetic (GTEM) chamber. The thymus tissue presented several morphological changes, including increased distribution of blood vessels along with the appearance of red blood cells and hemorrhagic reticuloepithelial cells, while the glucocorticoid receptors presented greater immunomarking on the thymic cortex in exposed animals. These results indicate that non-ionizing sub-thermal radiation causes changes in the endothelial permeability and vascularization of the thymus, and is a tissue-modulating agent for Hsp90 and GR.
Irradiation was performed during three weeks, after which plants were removed from the chambers for measurements of volatile organic compound (VOC) emission and analyses of leaf structure and essential oil content. All measurements of VOC emission and analyses of leaf structure and essential oil content have been replicated with eight different plants.

Wi-Fi certainly isn’t going to do you in, but something else you forgot to worry about while you were worrying about your Wi-Fi router might: put that worry to good use and make sure there are fresh batteries in your smoke detectors, that you’re planning on getting a yearly physical this year, and you floss before bed (you know, those things you’ve been putting off that might actually, sooner or later, harm you).
In the years to come, the WTR’s cautionary findings would be replicated by numerous other scientists in the United States and around the world, leading the World Health Organization in 2011 to classify cell-phone radiation as a “possible” human carcinogen and the governments of Great Britain, France, and Israel to issue strong warnings on cell-phone use by children. But as the taxi carried Carlo to Louis Armstrong International Airport, the scientist wondered whether his relationship with the industry might have turned out differently if cell phones had been safety-tested before being allowed onto the consumer market, before profit took precedence over science. But it was too late: Wheeler and his fellow executives had made it clear, Carlo told The Nation, that “they would do what they had to do to protect their industry, but they were not of a mind to protect consumers or public health.”14
Wireless devices run on radio waves. Antennas emit varying levels of radio frequencies (RFs) that at some point are absorbed into the human body. The measurement of absorption, the Specific Absorption Rate (SAR), is an indicator of this absorption. What’s the SAR of a cell phone? The FCC requires that all models of cell phones sold in the U.S. fall below 1.6 watts per kilogram. If you’re confused by the complex science, you’re not alone.

Lloyd is correct. I’ve worked in wireless equipment design for over 30 years, from 30kHz to 3GHz, milliwatts to many-watts. In the late 2000’s I personally set the safety standards for wireless charging (WPC’s “Qi” format) after lengthy research. Starting at 400MHz and above, DNA strands can be broken or inflicted with sequence translocation when the applied fields excite mechanical shake, twist, and compression resonances of the helixes. Those would be cancer-provoking damage. Below 300MHz I’m not aware of significant non-thermal biological effects, which explain how we’ve been “lucky” with AM/FM radio, walkie talkies, CB’s, shortwave, and VHF TV not harming people en masse.


DefenderShield Cellphone Radiation Case also claims independent testing and says in their website: That a "sophisticated layering of separate non-toxic, human safe materials processed for maximum radiation blocking efficiency. Each material has unique and targeted radiation-shielding characteristics designed to work in unison to eliminate all radiation emissions from 0 to 10 GHZ and Defender Shield technology refracts, conducts and finally absorbs all these potentially harmful emissions."  In this demonstration, the radiation level measured when DefendeShield case was on is still quite a bit above the level of exposure that I would recommend. I personally do not recommend-holding a phone with a shielding case to your head as the DefenderShield website shows a young woman doing as she demonstrates the product. 
I have many times experienced heavily disturbed sleep when wifi has been on in the same house I have been sleeping in. If it is in my power I never have wifi or cellphones on at night, and only ever have them on when they are being used, as I find the radiation so disturbing. I have never before read any studies or reports about the ill-effects of this kind of radiation, as I didn’t feel the need to read about, since I could easily feel myself how bad the radiation is.

The World Health Organization International Agency for the Research on Cancer’s classification of wireless radiofrequency frequencies a Class 2B carcinogen includes wireless radiation from any transmitting source such as cellphones, baby monitors, tablets, cell towers, radar, other wifi, etc. The radiofrequency classification applies to RF-EMF in the range of 30 KHz to 300 GHz emitted from any device. Cell phone frequencies commonly start at 900 MHz (with some cell phones having up to 7 antennas all at different frequencies) and Wi-Fi device frequencies are at 2.45 GHz and 5GHz.
In February of 2008, a research study was published in the American Journal of Epidemiology. The study, conducted at Tel Aviv University, examined 500 Israelis who had developed salivary gland cancer and compared their level of mobile phone usage to 1,300 healthy adults. The researchers discovered that within the entire group, those who used their cell phone for a few hours a day had 50 percent higher odds of developing a salivary gland tumor.

I’ve started to shut off my WIFI from midnight until about sundown the next day. The results have been astounding. I’ve been having serious joint aches and I’m not THAT old. Enough that it was hampering my quality of life. So I did an experiment. I turned off my WIFI router and took out the battery. Been doing this now for 2 days and I’m telling you I’m a new woman. I’m a little stiff getting out of bed in the morning but nothing like I was.

Wireless internet (Wi-Fi) electromagnetic waves (2.45 GHz) have widespread usage almost everywhere, especially in our homes. Considering the recent reports about some hazardous effects of Wi-Fi signals on the nervous system, this study aimed to investigate the effect of 2.4 GHz Wi-Fi radiation on multisensory integration in rats. This experimental study was done on 80 male Wistar rats that were allocated into exposure and sham groups. Wi-Fi exposure to 2.4 GHz microwaves [in Service Set Identifier mode (23.6 dBm and 3% for power and duty cycle, respectively)] was done for 30 days (12 h/day). Cross-modal visual-tactile object recognition (CMOR) task was performed by four variations of spontaneous object recognition (SOR) test including standard SOR, tactile SOR, visual SOR, and CMOR tests. A discrimination ratio was calculated to assess the preference of animal to the novel object. The expression levels of M1 and GAT1 mRNA in the hippocampus were assessed by quantitative real-time RT-PCR. Results demonstrated that rats in Wi-Fi exposure groups could not discriminate significantly between the novel and familiar objects in any of the standard SOR, tactile SOR, visual SOR, and CMOR tests. The expression of M1 receptors increased following Wi-Fi exposure. In conclusion, results of this study showed that chronic exposure to Wi-Fi electromagnetic waves might impair both unimodal and cross-modal encoding of information.
The International Agency for Research on Cancer (IARC) has classified cell phone radiation as a possible carcinogen. On May 31, 2011, the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) issued a press release announcing it had added cell phone radiation to its list of physical agents that are "possibly carcinogenic to humans" (group 2B agents). [38] The classification was made after a working group of 31 scientists completed a review of previously published studies and found "limited evidence of carcinogenicity" from the radiofrequency electromagnetic fields emitted by wireless phones, radio, television, and radar. [37]
