evidence: WiFi and the electronic devices that connect to it, such as cellphones, laptops, and wireless headphones, are all around us. So far, there is no consistent evidence that WiFi routers or WiFi-powered devices increase cancer risk. [...] Wireless networks stream invisible radio waves, a form of radiofrequency radiation (EMFs), through the air — similar to cellphones, computers, Bluetooth speakers, and other WiFi-powered devices. [...] Non-ionizing EMF is low-level radiation which is generally viewed as harmless. Routers and electronic devices, such as cellphones, computers and laptops, and Bluetooth devices (such as wireless headphones) emit this type of radiation. The main concern regarding this type of EMF is although it is low-frequency, electronic devices are all around us, and always on.
