evidence: There are mixed opinions regarding the effect of WiFi exposure on human health. While some studies show that WiFi has adverse health effects, there are reports claiming that radiofrequency signals from wireless networks are too low to cause any damage to the human systems. [...] The artificial EMF of a WiFi system is generally polarized, which is potentially more dangerous than a non-polarized one as it exerts relatively larger forces on electrically charged chemical groups. [...] Some studies regarding the effects of 2.45 GHz WiFi signals on both human and animal health have demonstrated that the radiofrequency electromagnetic radiation emitted by WiFi devices can affect sperm count, motility, and DNA integrity.
