WiFi operates in the 2 to 5 GHz range -- part of the microwave portion of the electromagnetic spectrum. This is in the same part of the spectrum where cell phones operate so I may refer to WiFi or cellphone electromagnetic radiation interchangeably. These are radio waves -- no different from those used to broadcast television programs, except that they are higher in frequency. They aren't nearly as high a frequency as visible light, and no one worries about getting cancer from visible light (ultraviolet light, on the other hand, causes skin cancer, but this is the minimum energy necessary to cause ionizations that can cause breaks in strands of DNA, which is the mechanism by which cancer cells can be created). There is no credible evidence that non-ionizing radiation has any adverse health effects at all. There is no radiobiologic mechanism that could explain such an association -- and absolutely no scientifically valid evidence that this has ever happened.
Add Negative Ions: Exposure to WiFi can result in the build-up of positive ions that can have negative effects on our bodies. We can neutralize this by adding negative ions to our lifestyle, negative ions are highest after a thunderstorm and are present from the energy caused by the crashing waves on the beach. You can also try a negative ion generator.
The HPA's position is that “...radio frequency (RF) exposures from WiFi are likely to be lower than those from mobile phones.” It also saw “...no reason why schools and others should not use WiFi equipment.”[4] In October 2007, the HPA launched a new “systematic” study into the effects of WiFi networks on behalf of the UK government, in order to calm fears that had appeared in the media in a recent period up to that time".[13] Dr Michael Clark, of the HPA, says published research on mobile phones and masts does not add up to an indictment of WiFi.[14][15]
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).
The International Agency for Research on Cancer (IARC) has classified cell phone radiation as a possible carcinogen. On May 31, 2011, the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) issued a press release announcing it had added cell phone radiation to its list of physical agents that are "possibly carcinogenic to humans" (group 2B agents). [38] The classification was made after a working group of 31 scientists completed a review of previously published studies and found "limited evidence of carcinogenicity" from the radiofrequency electromagnetic fields emitted by wireless phones, radio, television, and radar. [37]
Do cell phones cause cancer? The preliminary results of a massive, government-funded study suggest they could. This makes cell phone safety an incredibly important topic. The early findings in the $25 million U.S. National Toxicology Program animal study show exposure to very high signal cell phone radiation led to a slightly increased risk of malignant gliomas in the brain and schwannomas of the heart in male rats. Schwannomas are tumors that form in the nerve sheath. (1)

So for example, if you have a Samsung Galaxy S 5 you could turn it off completely (briefly pulling the battery if you need to) push the power button to turn the phone back on until you see the Samsung Galaxy S5 logo screen, release the power button and then immediately press and hold the Volume Down key until the phone booted up with Safe Mode activated displaying “Safe mode” in the bottom left hand corner of the phones display.
Who can master dropping their phone down that tiny slit that exists when the elevator doors open? This girl! My iPhone 5s SURVIVED an eight story plummet down the elevator shaft at work thanks to my Commuter Series case!!! I thought for sure the screen would be cracked and the phone would be in a million pieces, but the screen wasn’t cracked or even scratched for that matter and it fully functions! The case took a little beating and there is a dent on the phone, but that’s nothing compared to the alternative! Thanks for making such a great product!!!! And to think, I was just complaining that I wanted something less bulky!!!

And David Carpenter, M.D., director of the Institute for Health and the Environment at the University at Albany, says that while exposure from a single router in your home may be small, the risks could be greater in places that have dozens of laptops and routers working at the same time—such as school classrooms. Phillips notes that children’s developing bodies may be more vulnerable to all forms of radiation from devices.
The NTP study was to be peer-reviewed at a meeting on March 26–28, amid signs that the program’s leadership is pivoting to downplay its findings. The NTP had issued a public-health warning when the study’s early results were released in 2016. But when the NTP released essentially the same data in February 2018, John Bucher, the senior scientist who directed the study, announced in a telephone press conference that “I don’t think this is a high-risk situation at all,” partly because the study had exposed the rats and mice to higher levels of radiation than a typical cell-phone user experienced.50

It is useful to be aware of new health research regarding cell phone usage and cell phone radiation. The first cell phone call was made in 1985 and that phone cost $5,000 and weighed about 9 pounds. The change in size, weight and cost of devices today has probably led to over 50% of the human race owning a mobile device, the fastest growing technology on the planet.
