New research suggests Wi-Fi signals could be more harmful than we thought Could Wi-Fi signals coming from the typical internet router found in homes be damaging to us? A new study has found some interesting results. HAVE you ever wondered what the effect of all the wi-fi signals flying around us could actually be doing to our bodies? We walk around with mobiles in our pockets, sleep next to tablets on bedside tables, and use our laptops wirelessly. We're constantly being bombarded by an invisible fog of wi-fi signals and an experiment has just found it could be killing plants, so could we be at risk, too? The Daily Mail reported an experiment, which saw two trays of cress seeds placed next to two wi-fi routers and another tray in a room without. It was carried out as a school project in Denmark and has attracted attention from top boffins and sparked a lively debate within science circles. The results found that many of the seeds next to the routers "turned brown and died" after 12 days which has raised fears that wi-fi signals could be more damaging than we thought. However, the debate rages that another reason for the negative result was due to the added heat in the room from the two routers drying out the seeds. This isn't the first study into the effect of radiation on trees and plants as scientists in the Netherlands exposed trees to varying levels of frequencies and found abnormalities on the leaves that indicated the upper and lower epidermis had been dying. While it is true wi-fi waves are a form of radiation the levels being emitted from a router are extremely low. The article explains that one would have to sit in a hotspot for a whole year in order to be exposed to the same level of radio wave emitted from a 20-minute mobile call. No known physical human damage has ever been recorded from wi-fi router signals and in order to raise body temperature, which is known as thermal interaction, bodies would have to be exposed to incredibly high levels. Until officially said otherwise, we're safe.
