After a few years of mystery it looks like I finally solved what causes my poke-in-the-eye headaches. It is most likely the wifi router!!! I am not 100% sure but this theory is the best candidate, and if you think humans can not be effected by wifi, think otherwise: http://carny.hubpages.com/hub/wifi-headaches For years I have had 2-3 head aches a month but mostly between Sept and May. Well this is also the time when I spend more time in the room upstairs where the router is. When I sleep in that bed my head is only 5-6 feet away from the router. About a week ago I relocated the router to downstairs and although it might be early to tell, but so far so good, not to mention it improved the reception in the house all over. Since I wired 3 rooms in the house, I might have to put another router back, but I think I am going to tinfoil it and just use it as a normal router, not as a wifi device. It is also possible that the set up also contributed to the pain, because there is a large TV opposite the router that might reflected back the signals thus giving me a double dose. The router is now next to a TV and I only get close to it when we watch TV, but the distance is about 8-9 feet and it is much less time than sleeping next to it... Well, as I said, it might be too early to tell, but I will use this thread and update monthly or so on the status of my headaches. Share your similar experience here. Oh yes, another interesting thing. I used to sit at a desk and the router was just down at my feet and for years I was getting groin aches too. I haven't used that desk for 2 or so years and my groin ache is also gone. Could it be that I am just too sensitive to electric energy???
