What does this tell us about Wi-Fi? Wi-fi routers are weaker transmitters even than mobile phone masts, and users sit away from them. The level of energy produced by a Wi-Fi router is very low, far too low to be able to disrupt DNA, so there is no mechanism for it to be carcinogenic. It’s true that it’s the same frequency as microwave radiation, but it’s so low power that there isn’t even a noticeable heating effect, never mind breakdown of genetic material. The ‘hot ear’ effect that you notice after a long call comes from the battery warming up, not radiation. It’s just too weak to do anything, even if you’re sitting close to it.
…Because we’ve known for a long time that the heat generated by laptops kills sperm. Well, now it turns out that heat isn’t the only threat to a man’s virility. Research has found exposure to Wi-Fi frequencies reduce sperm movement and cause DNA fragmentation.  Both human and animal testing has confirmed that exposure negatively affects sperm.  
The present study tested the effects of Wi-Fi (2.45 GHz for 1h) exposure on Ca(2+) influx, oxidative stress and apoptosis through TRPV1 channel in the murine dorsal root ganglion (DRG) and hippocampus of pentylentetrazol (PTZ)-induced epileptic rats. The cytosolic free Ca(2+), reactive oxygen species production, apoptosis, mitochondrial membrane depolarization, caspase-3 and -9 values in hippocampus were higher in the PTZ group than in the control although cell viability values decreased. The Wi-Fi exposure induced additional effects on the cytosolic Ca(2+) increase. However, pretreatment of the neurons with CPZ, results in a protection against epilepsy-induced Ca(2+) influx, apoptosis and oxidative damages. In conclusion, epilepsy and Wi-Fi in our experimental model is involved in Ca(2+) influx and oxidative stress-induced hippocampal and DRG death through activation of TRPV1 channels, and negative modulation of this channel activity by CPZ pretreatment may account for the neuroprotective activity against oxidative stress.
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.
In a separate study by the same Swedish team, they found more than seven times the risk among people using a cell phone more than 20 years and 6.5 times the risk for long-term users of cordless phones. As expected, most of the gliomas and acoustic neuromas were on the same side of the head, which was usually exposed to the phone. In the 2013 official report on the medical evidence for brain tumors, the International Agency for Research on Cancer concluded that radiation from cell phones is “possibly carcinogenic to humans”.
