The WHO began to study the health effects of electric- and magnetic-field radiation (EMF) in 1996 under the direction of Michael Repacholi, an Australian biophysicist. Although Repacholi claimed on disclosure forms that he was “independent” of corporate influence, in fact Motorola had funded his research: While Repacholi was director of the WHO’s EMF program, Motorola paid $50,000 a year to his former employer, the Royal Adelaide Hospital, which then transferred the money to the WHO program. When journalists exposed the payments, Repacholi denied that there was anything untoward about them because Motorola had not paid him personally. Eventually, Motorola’s payments were bundled with other industry contributions and funneled through the Mobile and Wireless Forum, a trade association that gave the WHO’s program $150,000 annually. In 1999, Repacholi helped engineer a WHO statement that “EMF exposures below the limits recommended in international guidelines do not appear to have any known consequence on health.”34
Two wireless trade associations contributed $4.7 million to the Interphone study launched by the WHO’s International Agency for Cancer Research in 2000. That $4.7 million represented 20 percent of the $24 million budget for the Interphone study, which convened 21 scientists from 13 countries to explore possible links between cell phones and two common types of brain tumor: glioma and meningioma. The money was channeled through a “firewall” mechanism intended to prevent corporate influence on the IACR’s findings, but whether such firewalls work is debatable. “Industry sponsors know [which scientists] receive funding; sponsored scientists know who provides funding,” Dariusz Leszczynski, an adjunct professor of biochemistry at the University of Helsinki, has explained.35
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).
By comparison, even a very powerful high-end Wi-Fi router only produces around 1 watt of microwave energy and, unlike the magnetron in a microwave oven, a Wi-Fi router radiates that minuscule 1 watt of power in a bubble-like-cloud around the router. In other words, if you wanted to heat up even a milliliter of water above room temperature using this energy, you’d be waiting…well, forever.
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. 
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).
In June of 2008, a Japanese study, published in the British Journal of Cancer, considered how mobile phone radiation levels affected different parts of the brain. After studying the mobile phone use of 322 brain cancer patients and 683 healthy adults, the study concluded that using a mobile phone "regularly" did not increase the risk of brain cancer.
The energy of electromagnetic radiation is determined by its frequency; ionizing radiation is high frequency, and therefore high energy, whereas non-ionizing radiation is low frequency, and therefore low energy. The NCI fact sheet Electromagnetic Fields and Cancer lists sources of radiofrequency radiation. More information about ionizing radiation can be found on the Radiation page.
Hi August and Tech Wellness Team. We at SafeSleeve salute you for your effort to educate and provide solutions for the hidden dangers of EMF radiation exposure from wireless electronics. Like you, we’ve worked extremely hard to provide a practical solution for EMF exposure and, as verified by our independent lab testing, we believe we’ve found an extremely effective and practical solution. While I cannot speak for the other devices you tested here, there are some key points about our SafeSleeve technology that we wanted to make sure you took into consideration:
The present study was designed to determine the effects of 2.45 GHz radiation (1, 2, 12, or 24 hours) on the antioxidant redox system, calcium ion signaling, cell count and viability in human leukemia 60 cells.The extent of lipid peroxidation, cytosolic free Ca²⁺ and cell numbers were higher in 2.45 GHz groups than in the controls and was time-dependent. 2.45 GHz electromagnetic radiation appears to induce proliferative effects through oxidative stress and Ca²⁺ influx although blocking of transient receptor potential melastatin 2 channels by 2-aminoethyl diphenylborinate seems to counteract the effects on Ca²⁺ ions influx.
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.
