According to an anonymous questionnaire, daily active cell phone usage was divided into three groups as following: Group A, < 30 min/d; Group B, from 30 min/d to 2 h/d; and Group C, > 2 h/d. Habits of carrying a mobile phone was recorded as (A) in the pocket of trousers, (B) in a handbag, or (C) in the pocket of jackets. Wireless internet usage was divided in to three groups, Group A: < 30 min/d; Group B, from 30 min/d to 2 h/d; and Group C, > 2 h/d. Internet usage types recorded as wireless or not.
The objective of this study was to investigate effects of 2.437 GHz radiofrequency radiation (24h/day for 20 weeks) emitted from indoor Wi-Fi Internet access devices on rat testes using histological and immunohistochemical methods. Researchers observed significant increases in serum 8-hydroxy-2′-deoxyguanosine levels and 8-hydroxyguanosine staining in the testes of the experimental group indicating DNA damage due to exposure (p < 0.05) as well as decreased levels of catalase and glutathione peroxidase activity in the experimental group, which may have been due to radiofrequency effects on enzyme activity (p < 0.05). These findings raise questions about the safety of radiofrequency exposure from Wi-Fi Internet access devices for growing organisms of reproductive age, with a potential effect on both fertility and the integrity of germ cells.
The present study was undertaken to determine the influence of low intensity microwave radiation (900, 1800, or 2450 MHz for 2h/day, 5days/week, for 60 days) on oxidative stress, inflammatory response and DNA damage in rat brain. Low intensity microwave exposure resulted in a frequency dependent significant increase in oxidative stress markers, reduced levels of GSH and SOD, increased levels of pro-inflammatory cytokines, and significant DNA damage in microwave exposed groups compared to controls. In conclusion, the present study suggests that low intensity microwave radiation induces oxidative stress, inflammatory response and DNA damage in brain by exerting a frequency dependent effect. The study also indicates that increased oxidative stress and inflammatory response might be the factors involved in DNA damage following low intensity microwave exposure.

I had a wireless router installed about a month ago, since then I have had trouble sleeping and also it was like something was inflaming my brain (don’t know how else to describe it). I stumbled onto the discussion about WiFi and problems associated with it and decided to turn off the WiFi on my router and just go with a wired connection. Instantly the pressure on brain was gone, its like my brain began to relax once the wireless was off. How can they say there is no evidence?

Also of note, in a study by Henrietta Nittby et al (2009), the lowest exposure SARs were worse than the higher SAR exposures. Some scientists consider blood brain barrier effects at these very low levels of radiation exposure (i.e. 30-45x lower than the ‘Top 10’ lowest SAR phones ranked by the Environmental Working Group) to be of equal or even greater concern for the population than the increase in brain tumors from cell phone use that is expected.
Here we studied the influence of microwave irradiation at bands corresponding to wireless router (WLAN) and mobile devices (GSM) on leaf anatomy, essential oil content and volatile emissions in Petroselinum crispum, Apium graveolens and Anethum graveolens. Microwave irradiation resulted in thinner cell walls, smaller chloroplasts and mitochondria, and enhanced emissions of volatile compounds, in particular, monoterpenes and green leaf volatiles. There was a direct relationship between microwave-induced structural and chemical modifications of the three plant species studied. These data collectively demonstrate that human-generated microwave pollution can potentially constitute a stress to the plants.
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
Safety standards do exist for radio frequency radiation emissions, but these standards are only based on thermal heating effects. That is to say they only consider these exposures to be harmful if they heat tissue. But these safety standards do not protect us from adverse biological effects which are thought to be the precursor to serious diseases. Scientists have already raised the alarm regarding this issue.
A study by the Corporate EME Research Laboratory and Motorola Florida Research Laboratories tested 9 different cell phone radiation shields, 5 of which claimed to block 99% of cell phone radiation. The other 4 shields tested claimed to emit a reverse radiation that would cancel out the harmful radiation from cell phones. The study found that all of the radiation shields had no effect on the amount of radiofrequency radiation a cell phone user is exposed to from their phone.[2]
One of the convenient features of having a smartphone is to quickly access email or social media accounts with just a tap of a finger. However, this also means that you are always connected to accounts that may contain sensitive information. Consider logging out of certain accounts if you can so that others can’t access those accounts if they are using your phone. Keep in mind that depending on the type of phone you have, you might not be able to log out of some accounts, such as email accounts, but may have to remove the entire account from your phone. In this case, make your decision based on your own privacy and safety risk. While it may be inconvenient to access the account through the browser instead, it may be safer.
"For example," Johnson said, "what does a fractal like pattern have to do with a hologram? The answer is, of course, nothing that is apparent. Then there is a truly convoluted assertion that cell phones can be instrumental in ‘psychoemotional' effects on humans because of their lower-frequency outputs. This too, is gibberish. In short, this is technobabble that will potentially snow someone who has no science background."

The very next day, a livid Tom Wheeler began publicly trashing Carlo to the media. In a letter he shared with the CEOs, Wheeler told Carlo that the CTIA was “certain that you have never provided CTIA with the studies you mention”—an apparent effort to shield the industry from liability in the lawsuits that had led to Carlo’s hiring in the first place. Wheeler charged further that the studies had not been published in peer-reviewed journals, casting doubt on their validity.10


Since we have this subconscious, ever-present fear of death, we employ magical thinking to give us a false sense of power over it. When we create artificial threats to our survival in our imagination, and then avoid practicing behaviors that make us vulnerable to those threats, we feel we have some power over whether we live or die. These are also known as superstitions.
For example, the latency period for radiation induced malignancies is, on the average, say 20 years, but epidemiologic studies of large groups of people (that only require a few thousand patients to reach statistical significance) exposed to ionizing radiation start showing an increase above baseline by seven years. So conservatively, there should be at least a few excess cases of glioma caused by cellular (or WiFi) electromagnetic radiation by now.
There has been no rise in the rate of brain cancers despite a massive increase in the use of cell phones. If cell phones were causing cancer we could expect a significant rise in the rate of brain and other related cancers. According to the National Cancer Institute, there was no increase in the incidence of brain or other nervous system cancers between the years 1987 and 2005 despite the fact that cell phone use dramatically increased during those same years. [6] Between 2004 and 2010 there was still no significant change in the incidence rate of brain tumors. Between 2004 and 2010 there was a slight increase from 209 cases to 221.8 cases per 100,000 people, but this slight increase was attributed to better tracking and recording of cases. [43] During the same time period, cell phone use increased 62.7% from 182,140,362 subscribers in 2004 to 296,285,629 in 2010. [44]
In 2011, the World Health Organization  classified radio frequency radiation of the type used by WiFi devices as a Group 2B possible carcinogen. A study conducted by the University of Vienna have found WiFi exposures to cause genotoxicity as they break single and double strand DNAs in our body. This indicates that there are effects that may potentially surface with our future generations.

“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

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


This investigation concerns with the effect of low intensity microwave (2.45 and 16.5 GHz, SAR 1.0 and 2.01 W/kg, respectively) radiation on developing rat brain when exposed for 35 days.  Results showed that the chronic exposure to these radiations caused statistically significant (p<0.001) increase in DNA single strand breaks in brain cells of rat.

Our homemade demonstration of all the cases uses a working phone. Not the shielding material by itself, but the actual "shielding" SafeSleeve, Pong, Reach,  Vest, ShieldMe, and Defender Shield cases. First we get RF power density measurements from a phone that's on a call and then, in the same location, within minutes of the first reading, we place the same phone as it's engaged in a call into each case and we take additional reading with the meter.
This study measured the levels of blood lipid peroxidation, glutathione peroxidase, reduced glutathione, and vitamin C to follow the level of oxidative damage caused by 2.45 GHz electromagnetic radiation exposure (60 min/day for 28 days) in rats. The possible protective effects of selenium and L-carnitine were also tested and compared to untreated controls.  Researchers found that 2.45 GHz electromagnetic radiation caused oxidative stress in blood of rat. L-carnitine seems to have protective effects on the 2.45-GHz-induced blood toxicity by inhibiting free radical supporting antioxidant redox system although selenium has no effect on the investigated values.
Dr. Carlo, wrote a  Medical Alert ten years ago. He cautioned people with EMF sensitivity against relying upon widely-available EMR Protection Products to prevent the effects of EMF exposure. He noted that EMF sensitive individuals were reporting the opposite effect: people found their symptoms and/or sensitivity worsened. Specifically, severe “symptom relapses.” Dr. Carlo noted:

43. Search for the unknown callers. Discovering unknown or anonymous numbers on your child’s phone can be alarming, but a bit of detective work can lead you to answers. “Now that you know who your kid chats with, you can see if there are any messages that make you suspicious. If you spot a phone number you don’t recognize, do a reverse phone lookup to discover exactly who they are talking to. By searching any domestic number, you may discover the texter’s name, carrier, and address.
If you're looking for ways to limit your exposure to the electromagnetic emissions from your cell phone, know that, according to the FTC, there is no scientific proof that so-called shields significantly reduce exposure from these electromagnetic emissions. In fact, products that block only the earpiece – or another small portion of the phone – are totally ineffective because the entire phone emits electromagnetic waves. What's more, these shields may interfere with the phone's signal, cause it to draw even more power to communicate with the base station, and possibly emit more radiation.
A wallet case turns an essential, expensive object into a thing that’s basically invaluable and super hard to replace. Suddenly every important and useful thing you need every day is stored in one teensy container. What would you even do if you lost this? I don’t have landline! I can’t call the bank to cancel my cards. I can’t buy a phone to call the bank because I have no money. My passport is expired, so when I go to the bank, I can’t identify myself to get an ATM card. I suppose my first course of action would be to dredge up my birth certificate and go to the DMV to get a new license. THE DMV! Rest in peace Mario, he starved to death in the waiting room.

Infertility is a common disorder that affects 15% of couples and nearly half of the cases are due to male infertility. As mentioned above, RF-EMR affects many organs including the testes by a direct or a thermal effect [6]. In one study, detrimental effects of RF-EMR on Leydig cells, seminiferous tubules, and especially the spermatozoa were clearly defined [1]. Although RF-EMR reduces testosterone levels, impairs spermatogenesis, and causes sperm DNA damage [4], the relationship between RF-EMR devices and male infertility is still controversial.
Last night unfortunately I had to sleep part of the night near a wifi router, and I felt I was being fried… as if been cooked in a microwave oven (though I never experienced that). I could hardly sleep at all until I moved (into the garden). I felt like my ovaries were directly being damaged, and felt that cyst or tumour growth would start if under longer exposure.
In 2015, scientists from around the world united for the International EMF Scientist Appeal based on the results of over 2,000 research papers. The appeal is the collective voice of 190 scientists from 39 different countries. They are calling for tighter regulations and more security measures when dealing with electromagnetic field exposures generally, and WiFi in particular.
... our review shows that there is a substantial amount of studies which indicate that plants have experienced physiological or morphological changes due to radiofrequency radiation and show statistically significant changes for the short-term exposure duration (up to 13 weeks). In contrast, the results obtained from the long-term exposure studies (two publications using nine different exposures with exposure duration between 3 months to 6 years) support no physiological effects on plants when exposed to radiofrequency radiation from mobile phone radiation. This would bring a remarkable point to the discussion about the apparent absence of response to the long-term exposure that may be interpreted as adaptations. On the other hand, phenotypic plasticity of plants will permit them to change their structure and function; hence, plants to adapt to environmental change (Nicotra et al., 2010). Plants are naturally affected by environmental stresses due to their immobility. Plants could respond to the environmental factors of wind, rain, electric field and ultraviolet radiation and adjust its physiological condition to adapt to the change of environment (Braam and Davis, 1990; Braam et al., 1996; Mary and Braam, 1997) .... our previous findings (Halgamuge et al., 2015) indicate that the biological effects considerably relied on field strength and amplitude modulation of the applied field.
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]
As our video points out: Measurements will vary with signal strength and other factors and that includes ambient energy. I talk about ambient energy in a lot of my videos-it's the energy that's in whatever environment I happen to be measuring in that's coming from a source of wireless energy that isn't the subject of what I'm measuring.  My home is not a lab of course, but fortunately it's always measured very low for RF radiation. 
The HPA's position is that “...radio frequency (RF) exposures from WiFi are likely to be lower than those from mobile phones.” It also saw “...no reason why schools and others should not use WiFi equipment.”[4] In October 2007, the HPA launched a new “systematic” study into the effects of WiFi networks on behalf of the UK government, in order to calm fears that had appeared in the media in a recent period up to that time".[13] Dr Michael Clark, of the HPA, says published research on mobile phones and masts does not add up to an indictment of WiFi.[14][15]

5. “Claw” your fingers around your phone. “This tight grip will make it harder for anyone to snatch your phone out of your hands. Not sure how to master the claw? No worries! CNET gives a great explanation: ‘Grip the phone securely in your hand, fanning out your fingers so that you’ve formed a protective cage or claw around the phone.’ For even more claw-like protection, you can weave your fingers around the device.” – Kyle Therese Cranston, 4 Tips for Keeping Your Cell Safe on Public Transportation, Edenred Commuter Benefit Solutions; Twitter: @CommuterBenefit
