Studies by five independent research groups regarding cell phones and brain tumors have revealed significantly increased risks of a benign tumour of the cranial nerve supplying the ear. This grows slowly and must be removed in a major operation that can result in permanent facial paralysis. Other risks found were cancer of the glial cells (including neurons) of the nervous system and cancer of the meninges, the membrane covering the brain and spinal cord.
What does this tell us about Wi-Fi? Wi-fi routers are weaker transmitters even than mobile phone masts, and users sit away from them. The level of energy produced by a Wi-Fi router is very low, far too low to be able to disrupt DNA, so there is no mechanism for it to be carcinogenic. It’s true that it’s the same frequency as microwave radiation, but it’s so low power that there isn’t even a noticeable heating effect, never mind breakdown of genetic material. The ‘hot ear’ effect that you notice after a long call comes from the battery warming up, not radiation. It’s just too weak to do anything, even if you’re sitting close to it.
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.
12. Contact your bank about a stolen phone. “Let your bank know if your phone or tablet is lost or stolen: If you use your mobile device for banking, it’s a good idea to alert your bank if your smartphone or tablet goes missing, even if you have a strong password and haven’t saved cookies from a previous session. That way, the bank can monitor your account for suspicious activities and set you up with new security measures right away.” – Stephen Ebbett, 6 Tips for Avoiding Identity Theft When Mobile Banking, About Money; Twitter: @AboutMoney
Cell phones emit radiofrequency (RF) radiation, and RF radiation has been shown to damage DNA and cause cancer in laboratory animals. A peer-reviewed Jan. 2012 study in the Journal of Neuro-Oncology concluded that RF radiation "may damage DNA and change gene expression in brain cells" in mice.  An Aug. 2009 meta-study found that RF radiation "can alter the genetic material of exposed cells."  A 2004 European Union-funded study also found that cell phone radiation can damage genes.  On May 26, 2016, the US National Toxicology Program (NTP) released the first results of its study on cell phone radiation, finding an increased incidence of malignant tumors of the brain (gliomas) and heart tumors (schwannomas) in rats exposed to RF radiation.  The NTP researchers also found DNA damage in the rats exposed to the highest levels of RF radiation.  On Nov. 1, 2018, the NTP released its final peer-reviewed report, concluding that there is "clear evidence of carcinogenic activity” in male rats exposed to RF radiation. 
People who say cell phones are safe reference statements by the FCC and Food and Drug Administration (FDA) and point to peer-reviewed studies which conclude that cell phone use is not associated with an increased risk of brain tumors or the onset of other health problems. They contend there has been no increase in brain tumor rates despite hundreds of millions of people now using cell phones.
Cell phone cases can make matters worse because they may block the phone’s antenna. The device must work harder to transmit signals which may lead to more radiation exposure for the user. (See safety tip #6 for more on the importance of a strong signal.) Certification testing done by phone manufacturers are done with bare phones with no accessories.
Although recall bias is minimized in studies such as COSMOS that link participants to their cell phone records, such studies face other problems. For example, it is impossible to know who is using the listed cell phone or whether that individual also places calls using other cell phones. To a lesser extent, it is not clear whether multiple users of a single phone, for example family members who may share a device, will be represented on a single phone company account. Additionally, for many long-term cohort studies, participation tends to decline over time.
“When symptoms are not addressed comprehensively– for example, using symptom amelioration without simultaneous elimination of exposure – cell membrane adverse reaction and damage continue to occur while the patient is assuming the cause of the problem has been eliminated. This lulls patients into a false sense of security, causing them to aggravate their exposures through the increased use of their wireless devices. When the damage reaches a critically harmful level, even the symptom amelioration can no longer be sustained by the damaged cells.”
The present study aimed to investigate the protective effects of melatonin against oxidative stress-mediated testicular impairment due to long-term exposure (2 h/day for 45 days) of 2.45 GHz Microwave Radiation. Result shows that melatonin prevented oxidative damage biochemically by significant increase (p < 0.001) in the levels of testicular LDH-X, decreased (p < 0.001) levels of MDA and ROS in testis (p < 0.01). Meanwhile, it reversed the effects of MWs on XO, protein carbonyl content, sperm count, testosterone level and DNA fragmentation in testicular cells. These results concluded that the melatonin has strong antioxidative potential against MW induced oxidative stress mediated DNA damage in testicular cells.
4. Erase your data with a swipe. “Apps like Find My iPhone and Lost will…allow you to remotely wipe the phone, erasing your personal data and restoring it to its original settings should it become stolen. This will help keep your passwords, logins, and online accounts safe.” – Amanda Perez, Cell Phone Safety Tips For Stolen Devices, ABC30; Twitter: @ABC30

Retrieved 2008-01-22. “Electromagnetic fields of all frequencies represent one of the most common and fastest growing environmental influences, about which anxiety and speculation are spreading. All populations are now exposed to varying degrees of EMF, and the levels will continue to increase as technology advances.”
Now, what if I took that already precious treasure and stuck it in case that substantially increased the accumulation of value in one place by adding my driver’s license, MetroCard, ATM card, and credit card to the package? What if such a case made it possible to combine the pain of losing my phone with the inconvenience of losing my wallet in a brief moment of carelessness? We need not wonder, because that’s exactly what a wallet case does.
If you think your heart races when surrounded by wireless networks or 3G or LTE cell phones, it may not be in your head. A study involving 69 subjects reported that many of them experienced a real physical response to electromagnetic frequencies. Exactly what was the physical response? Increased heart rate — similar to the heart rate of an individual under stress. 
Supermarkets or plant nurseries (plants); WiFi hotspots are available in many homes and commercial establishments. If the student does not have a wireless device that displays WiFi signal strength, an inexpensive standalone wireless signal detector may be purchased on the Internet. Plant lights may be purchased on the Internet and at garden supply stores.
Although uterine lipid peroxidation increased in the EMR groups, uterine glutathione peroxidase activity (4th and 5th weeks) and plasma prolactin levels (6th week) in developing rats decreased in these groups. In the maternal rats, the plasma prolactin, estrogen, and progesterone levels decreased in the EMR groups, while the plasma total oxidant status, and body temperatures increased. There were no changes in the levels of reduced glutathione, total antioxidants, or vitamins A, C, and E in the uterine and plasma samples of maternal rats.
According to the results of the current research, long-term exposure to EMR emitted from wireless devices had adverse effects on the antioxidant potential of blood. Therefore, to protect individuals from harmful effects of Wi-Fi signals, it is advised to limit the use of such devices for household and occupational activities, if possible. This study may stimulate future helpful research in the development of new protective or therapeutic approaches. In addition, it is recommended that the target tissues of EMR emitted from wireless devices and the level of other mediators be investigated to understand the exact molecular mechanism and site of action upon continuous exposure to such radiations.
You can search for the most popular cell phone cases and covers, browse cases and covers by brand, and even refine your search by need. Cell phone cases provide a variety of protection. Some people put a large emphasis on military-grade protection, to ensure that all angles of their case are secure, no matter the terrain. Others may desire cases that give easy access to headphone ports or charging outlets, to have access to home speakers or audio cables. The engineering of cases can become even more specific—right down to the beveled edges that raise your screen protectively above a flat surface or the grip finish smoothly designed onto the back of your phone to ensure maximum ease in typing. Whatever your need, Amazon is sure to carry the brand, features, and colors you care about. Check the Deals page regularly to even see some of your favorite cases on discount. Amazon is sure to carry the widest selection of cases; you just worry about carrying yours.
We can’t stop people from misleading others for profit, but we can respond to their nonsense. We’ve received more than a few letters here at How-To Geek from concerned readers asking if they should turn off their wireless equipment when not in use, or get rid of it altogether. So we’ve decided to add a reasonable voice to the conversation so, hopefully, people will find this and breathe a much deserved sigh of relief.
Electrocardiogram and arterial pressure measurements were studied under acute exposures to WIFI (2.45GHz) during one hour in adult male rabbits. 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, but failed to alter maximum amplitude and P waves. After intravenously injection of dopamine (0.50ml/kg) and epinephrine (0.50ml/kg) under acute exposure to RF we found that, WIFI alter catecholamines (dopamine, epinephrine) action on heart variability and blood pressure compared to control. These results suggest for the first time, as far as we know, that exposure to WIFI affect heart rhythm, blood pressure, and catecholamines efficacy on cardiovascular system; indicating that radiofrequency can act directly and/or indirectly on cardiovascular system.
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…)
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.
