A negative reaction to wireless signals. Also called "gadget allergies," symptoms can be headaches, nausea, ringing in the ear (Tinnitus), fatigue, irritability, fainting and pain throughout the body. In order to feel improvement, some people have moved into remote areas; however, it is difficult to avoid wireless signals no matter where you are on the planet. A Very Controversial Subject Although studies relating to cellphones were inconclusive in the past, most of them were conducted by the cellular industry, and independent researchers have claimed foul play. However, people are increasingly speaking out because they are being affected. It is not unreasonable to think that the molecules of the human brain and body can be disturbed by the thousands of signals passing through them every second from AM, FM and HD Radio, satellite TV, radio and GPS, cellular voice and data, cordless phones, radar, smart electric meters, Bluetooth headphones, speakers, keyboards and mice, and especially the myriad applications of Wi-Fi. When people around the world swear they feel better after moving from the city to a rural location or when shutting down their Wi-Fi, it is reasonable to think that electromagnetic hypersensitivity (EHS) is very real. We humans have genetic differences that can result in different reactions or responses to the environment. Some may be very sensitive to radiation, while others are not. However, this is the first generation raised from infancy that is bombarded with wireless in such profusion, which has increased exponentially since the turn of the century. Solutions As a precaution, many people use wired earphones instead of holding the phone against their ear. Rather than stream video via Wi-Fi, households have switched from wireless to wired, running Ethernet cables from their router to their home theater equipment. The constant beaconing in a wireless router, which advertises the name of the Wi-Fi network all day long, can also be turned off (see SSID broadcast). In 2014, France took a major step by banning Wi-Fi entirely in nursery schools and turning Wi-Fi off in elementary schools when not specifically used for teaching. See SAR.
