Researchers have carried out several types of epidemiologic studies in humans to investigate the possibility of a relationship between cell phone use and the risk of malignant (cancerous) brain tumors, such as gliomas, as well as benign (noncancerous) tumors, such as acoustic neuroma (tumors in the cells of the nerve responsible for hearing that are also known as vestibular schwannomas), meningiomas (usually benign tumors in the membranes that cover and protect the brain and spinal cord), and parotid gland tumors (tumors in the salivary glands) (3).
Cell phone radiation may disrupt the functioning of pacemakers. A 2005 study in the International Journal of Cardiology found that mobile phones may have "adverse effects" on pacemaker functions under certain conditions.  According to the US Food and Drug Administration (FDA), radiofrequency energy from cell phones can create electromagnetic interference (EMI) that may disrupt the functioning of pacemakers, especially if the cell phone is placed close to the heart.  The American Heart Association includes cell phones on its list of "devices that may interfere with pacemakers." 
46. Tape your home number on your phone (or a parent’s cell phone number). “Imagine your child’s phone (or your own) is lost. Even if the person who finds it wants to return it, they have to go through your private information to find a number to dial. Make it easy. Tape your home number (or whatever number is suitable) to the back of the phone, along with information about a reward, if you like. That way, even with a password locking the keypad or screen, a do-gooder can get you your phone back!” – marianmerritt, Cell Phone Safety Tips for Kids, Norton Community by Symantec; Twitter: @NortonSupport
“See a name you don’t recognize? Get the lowdown on the mystery texter by conducting an online background check. Pull their criminal records to discover if they’ve potentially been convicted of anything serious, such as a sexual offense or other violent crimes. Being armed with this information is the first step to squashing your teen’s inappropriate relationship.” – Logan Strain, Who Has Your Kid Been Texting?

The legislators themselves say that no link has been demonstrated (Le Monde reports them as having been unable to identify ‘a causal link between the biological effects described on cellular models, animals or humans and possible health effects that result.’) and there is only limited evidence (one study, unconfirmed by any others) to suggest risk even for intensive users of mobile phones.
In recent years there has been a tremendous increase in use of Wi-Fi devices along with mobile phones, globally. Wi-Fi devices make use of 2.4 GHz frequency. The present study evaluated the impact of 2.45 GHz radiation exposure for 4h/day for 45 days on behavioral and oxidative stress parameters in female Sprague Dawley rats. Behavioral tests of anxiety, learning and memory were started from day 38. Oxidative stress parameters were estimated in brain homogenates after sacrificing the rats on day 45. In morris water maze, elevated plus maze and light dark box test, the 2.45 GHz radiation exposed rats elicited memory decline and anxiety behavior. Exposure decreased activities of super oxide dismutase, catalase and reduced glutathione levels whereas increased levels of brain lipid peroxidation was encountered in the radiation exposed rats, showing compromised anti-oxidant defense. Expression of caspase 3 gene in brain samples were quantified which unraveled notable increase in the apoptotic marker caspase 3 in 2.45 GHz radiation exposed group as compared to sham exposed group. No significant changes were observed in histopathological examinations and brain levels of TNF-α. Analysis of dendritic arborization of neurons showcased reduction in number of dendritic branching and intersections which corresponds to alteration in dendritic structure of neurons, affecting neuronal signaling. The study clearly indicates that exposure of rats to microwave radiation of 2.45GHz leads to detrimental changes in brain leading to lowering of learning and memory and expression of anxiety behavior in rats along with fall in brain antioxidant enzyme systems.
The FCC has granted the industry’s wishes so often that it qualifies as a “captured agency,” argued journalist Norm Alster in a report that Harvard University’s Edmond J. Safra Center for Ethics published in 2015. The FCC allows cell-phone manufacturers to self-report SAR levels, and does not independently test industry claims or require manufacturers to display the SAR level on a phone’s packaging. “Industry controls the FCC through a soup-to-nuts stranglehold that extends from its well-placed campaign spending in Congress through its control of the FCC’s congressional oversight committees to its persistent agency lobbying,” Alster wrote. He also quoted the CTIA website praising the FCC for “its light regulatory touch.”31
This overview shows that effects of 2.45 GHz radiation have been found by different research teams, repeatedly, in different study objects, and at different exposure levels. A broad spectrum of issues has been investigated such as the effects of 2.45 GHz radiation emitted by a Wi-Fi router on the release of mercury from amalgam fillings. The mercury levels were significantly increased (Paknahad et al. 2016).
As iPhones go, the iPhone SE is a bargain, but it doesn’t come cheap. Don’t let the pint-sized package fool you, however. The iPhone SE has a fast A9 processor, which is the same processor used in the iPhone 6S. It also comes with a crisp display and runs the latest version of iOS. The iPhone SE is a great choice for a child, too, given it features built-in parental controls. You can prevent your child from accessing the internet and using specific apps, for instance, or prevent them from making purchases in the App Store.
Remarkably, cell phones had been allowed onto the US consumer market a decade earlier without any government safety testing. Now, some customers and industry workers were being diagnosed with cancer. In January 1993, David Reynard sued the NEC America Company, claiming that his wife’s NEC phone caused her lethal brain tumor. After Reynard appeared on national TV, the story went viral. A congressional subcommittee announced an investigation; investors began dumping their cell-phone stocks; and Wheeler and the CTIA swung into action.2
TEXT MORE THAN TALK! Moving a cell phone even a 1/4 inch from the body can greatly reduce radiation exposure, at one inch the intensity is 16 fold less than 1/4 inch. Signal strength falls off as the square of the distance from the source. This means that if you double the distance to the source, RF intensity is four times less since two squared is four.
“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 reduced 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.”
Prenatal exposure to radiation from cell phones may increase the risk of ADHD and other behavior problems in children. According to a peer-reviewed Nov. 2008 study in the journal Epidemiology, exposure to cell phone radiation while in the womb "was associated with behavior difficulties such as emotional and hyperactivity problems around the age of school entry."  A Dec. 2010 study replicated those findings.  A peer-reviewed Mar. 15, 2012 study found that mice exposed to cell phone radiation in the womb "were hyperactive and had impaired memory" as adults. 
Everyone should be sleeping at bed time, and WiFi signal may interferes with the brain during sleep, so it is a good idea to turn it off before going to bed. This allows the body to rest more deeply. By turning it off at night, you are effectively cutting down exposure by 33%. (Aside from the WiFi reduction, many security experts also recommend turning off your internet when not using it).
33. Avoid Electro Hypersensitivity (EHS) due to the location of an Electromotive Force (EMF) source. “Don’t wear metal-rimmed glasses when using a cell phone,” advises the Center for Safer Wireless. Additionally, the Center for Safer Wireless suggests that you should “refrain from using your cell phone in a car, bus or train. Metal reflects wireless radiation, and it bounces around you when on a cell phone in this environment.”– Cell Phone Safety Tips, Center for Safer Wireless; Twitter: @SaferEMF
“It’s because WiFi is just a low frequency sound wave.” For me, the jury is still out concerning the link between WiFi and sleep disturbance. But I’m sorry, you are wrong about WiFi being a low frequency sound wave. It is a radio wave, i.e. electromagnetic, and it runs at 2.3 GHz and/or 5 GHz, which cannot by any stretch of the imagination be described as low frequency.
A 2012 study by NCI researchers (25) compared observed glioma incidence rates in U.S. SEER data with rates simulated from the small risks reported in the Interphone study (6) and the greatly increased risk of brain cancer among cell phone users reported in the Swedish pooled analysis (19). The authors concluded that overall, the incidence rates of glioma in the United States did not increase over the study period. They noted that the US rates could be consistent with the small increased risk seen among the subset of heaviest users in the Interphone study. The observed incidence trends were inconsistent with the high risks reported in the Swedish pooled study. These findings suggest that the increased risks observed in the Swedish study are not reflected in U.S. incidence trends.
The RF signals from cell phones, as well as Bluetooth and WiFi, are considered nonionizing forms of radiation. That means unlike ionizing radiation—from, say, ultraviolet light from the sun, medical tests such as CT scans or X-rays, or nuclear explosions—they don’t carry enough energy to directly break or alter your DNA, which is one way cancer can occur.

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
Exposure to ionizing radiation, such as from x-rays, is known to increase the risk of cancer. However, although many studies have examined the potential health effects of non-ionizing radiation from radar, microwave ovens, cell phones, and other sources, there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans (2).
This study was an in-vitro pilot study which established the effect of radiofrequency radiation from 2.4 GHz laptop antenna on human semen. A test of significance between results of semen parameters using Mann-Whitney U- test at 0.05 level of significance showed a significant effect of RFR exposure on sperm concentration, motility and morphology grading.

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.
Cooper's prototype arrived on the market a decade later at the staggering price of $3,995. Designed by Rudy Krolopp, it was known as the Motorola DynaTAC 8000X, or simply "the brick.” Featuring 20 large buttons and a long rubber antenna, it measured about 11 inches high, weighed almost 2 pounds, provided one hour of battery life and could store 30 phone numbers.
Wifi routers can and have still been able to emit frequencies even while turned off. So just, beware of that. I completely got rid of my wifi router at home. It’s to that point. Also save on the cable bill now so it’s a win win. Nope. Don’t need all that radiation just to have a “stronger” Internet connection for all my wireless devices! Haha, so u know what they did? The cable company cut off some channels that were in my package. To try and make me call back and pay to have extra channels. That’s why they ask you, what channels do you watch ? Try try to up sell sell sell you to get you to watch TV all day while your body is getting radiated all day from your wifi. Wether your hyper sensitive to it or not, like some of us are greatly effected, your health is still being effected.
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
…Because we’ve known for a long time that the heat generated by laptops kills sperm. Well, now it turns out that heat isn’t the only threat to a man’s virility. Research has found exposure to Wi-Fi frequencies reduce sperm movement and cause DNA fragmentation.  Both human and animal testing has confirmed that exposure negatively affects sperm.  
We requested semen for analyses from the male patients coming to our infertility division and also asked them to fill out an anonymous questionnaire. We queried their mobile phone and wireless internet usage frequencies in order to determine their radiofrequency-electromagnetic radiation exposure. A total of 1082 patients filled the questionnaire but 51 of them were excluded from the study because of azoospermia.
11. Sign out of your banking app when finished. “Don’t save your banking app ID on your device: Most apps give consumers the option to save their ID to that device. But if the smartphone or tablet falls into the wrong hands, the thief will have access to sensitive information, including balances and critical account numbers. Also make sure you sign out of the app after each session. Most apps automatically sign users out after a set time without detecting activity, but it’s safer to sign out immediately after each use.” – Stephen Ebbett, 6 Tips for Avoiding Identity Theft When Mobile Banking, About Money; Twitter: @AboutMoney
