The best things you can do are to dramatically lower the EMF radiation in your home by using less wifi, using ethernet instead, and a ton of other steps. Check out my posts “11 Ways To Reduce Computer EMF Exposure,” “11 Ways To Reduce EMF Exposure,” and “How To Eliminate EMFs In The Bedroom” for a whole wealth of helpful tips at lowering your exposure to EMF radiation.
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.
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." 
Some implanted medical devices use radio frequency communication - both to report status, and to allow changing device behavior. Emissions from wireless electronic devices can interfere with the functioning of these devices, thereby adversely affecting the health of the user. Users of such implanted devices are usually cautioned to avoid close exposure to other wireless devices.
25. Use your cell phone for emergencies or important calls only. “Turn your cell phone off more often. Reserve it for emergencies or important matters. As long as your cell phone is on, it emits radiation intermittently, even when you are not actually making a call. If you’re pregnant, avoiding or reducing your cell phone use may be especially important.” – Dr. Mercola, NEW Urgent Warning to All Cell Phone Users, Mercola.com; Twitter: @mercola
Hardell had already attracted the industry’s displeasure back in 2002, when he began arguing that children shouldn’t use cell phones. Two scientists with industry ties quickly published a report with the Swedish Radiation Authority dismissing Hardell’s research. His detractors were John D. Boice and Joseph K. McLaughlin of the International Epidemiology Institute, a company that provided “Litigation Support” and “Corporate Counseling” to various industries, according to its website. Indeed, at the very time Boice and McLaughlin were denigrating Hardell’s work, the institute was providing expert-witness services to Motorola in a brain-tumor lawsuit against the company.41
The NTP studied radiofrequency radiation (2G and 3G frequencies) in rats and mice (33, 34). This large project was conducted in highly specialized labs that specified and controlled sources of radiation and measured their effects. The rodents experienced whole-body exposures of 3, 6, or 9 watts per kilogram of body weight for 5 or 7 days per week for 18 hours per day in cycles of 10 minutes on, 10 minutes off. A research overview of the rodent studies, with links to the peer-review summary, is available on NTP website. The primary outcomes observed were a small number of cancers of Schwann cells in the heart and non-cancerous changes (hyperplasia) in the same tissues for male rats, but not female rats, nor in mice overall.
In a separate study by the same Swedish team, they found more than seven times the risk among people using a cell phone more than 20 years and 6.5 times the risk for long-term users of cordless phones. As expected, most of the gliomas and acoustic neuromas were on the same side of the head, which was usually exposed to the phone. In the 2013 official report on the medical evidence for brain tumors, the International Agency for Research on Cancer concluded that radiation from cell phones is “possibly carcinogenic to humans”.
