I feel this is an increasing problem emfs from neighbours that can have a huge impact on health. One of the most worrying symptoms i had was when i moved my settee directly onto a wall which i later found out was were my neighbours TV was behind not quite sure if its a plasma but i know shes got a satellite dish.After sitting down for a hour and then going to bed started getting a sudden lost of blood to my head this happened on about four seperate occasions for a few minutes.I decided to buy an acoustimeter and found i was receiving very high pulsed microwave radiation into my room from my neighbour.Moved by settee and successfully shielded my room.People who are aware of electrosensitivity i think are far more in tune with there health.
I have actually knocked on my apartment neighbors door below and above me and asked to see where their wireless routers were. They actually let me in and I scanned the place looking to see where the TV was, where the computer was, and what was where. Pretty obnoxious but necessary if you want to preserve your health.
Be aware of workplace too. If the people in the office next to yours has the back of their computer pointed at you, bad news.
Another thing we don't often pay attention to is wires in the floor. I am on an upper floor apartment, and there is a ceiling light above my computer work station. That means there is also a ceiling light in the unit below me, right where my feet rest. I have been getting volts up my legs and wonder if it is related to that.
I also check the balconies around me and even across the street to see if anyone has a Satellite dish pointed at me. They are everywhere.
There are so many sources of neighbors wireless and EMF's invading our air space it is mind boggling. We are now living in microwave and EMF ghettos.
