In my home and work environment I long ago made the decision to completely steer clear of WiFi. You might not feel you want to go “the whole nine yards” on this. Here are some ways you can reduce the burden of radio frequency radiation from WiFi on your body. You can pick and choose from this list according to how much you want to reduce WiFi radiation exposure in your life.
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.
In certain situations, it's necessary to use your cell phone when your hands are otherwise occupied. For those times, a Bluetooth headset comes in handy. These lightweight headsets attach above one or both of your ears or around your neck, and allow you to talk without having to do so directly into your phone. These are rechargeable devices that offer around eight hours of talk time. You can also listen to music and use GPS applications and many other apps that your phone has. Bluetooth headsets are compatible with most or all Bluetooth-enabled mobile devices.
gamma rays are constantly going through you as we speak as are wifi. that doesn’t mean however that you can create much usable electricity from them. you cannot. because the amount of energy inherent in these is miniscule. actually for somebody making judgements about what other people may or may not be you seem to be very ignorant about basic facts.
We aimed to investigate the effects of Wi-Fi-induced EMR on the brain and liver antioxidant redox systems in the rat during pregnancy and development. Sixteen pregnant rats and their 48 newborns were equally divided into control and EMR groups. The EMR groups were exposed to 2.45GHz EMR (1hour/day for 5 days/week) from pregnancy to 3 weeks of age. Brain cortex and liver samples were taken from the newborns between the first and third weeks.

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).

We investigated the effect of olive leaves extract administration on glucose metabolism and oxidative response in liver and kidneys of rats exposed to 2.45 GHz radiofrequency radiation (1h/day for 21 days). This exposure was shown to induce a diabetes-like status and also decreased the activities of glutathione peroxidase, catalase, superoxide dismutase, and groups thiol amount in liver and kidneys. Olive leaves extract administration (100 mg/kg, ip) in RF-exposed rats prevented glucose metabolism disruption and restored the activities of GPx, CAT and SOD and thiol group amount in liver and kidneys and was able to bring down the elevated levels of MDA in liver but not in kidneys. Our investigations suggested that RF exposure induced a diabetes-like status through alteration of oxidative response, while olive leaves extract was able to correct glucose metabolism disorder by minimizing oxidative stress induced by RF in rat tissues.
SafeSleeve Anti Radiation Case: Safe Sleeve website says they integrate FCC accredited independent lab tested "shielding technology" in their products. There are many links to "SafeSleeve, Is it a Scam?" and "Does SafeSleeve work?" online, but if you follow those links you'll find they go to the actual SafeSleeve site where the question of SafeSleeve protection is addressed.  You'll see in this demonstration that the radiation level was higher with the SafeSleeve Case on.

Joel Moskowitz (@berkeleyprc) of the University of California, Berkeley School of Public Health, US, says: “This is the largest technological experiment in the history of our species, with potential health risks we still know next to nothing about.” This view is shared by Denis Henshaw, professor of human radiation effects at Bristol University, UK, who said: “Vast numbers of people are using cell phones and this could be a time bomb of health problems.”
