if it makes any difference, I slept in a faraday cage for many years, built it just to test if it helped, and I slept fantastic after that. before I had it built I would wake up in the middle of the night (something like 3:17am) sexually aroused. it happened most every night at the same time down to the minute, and it even moved with daylights savings time... after I put up the faraday cage it did not happen. then I moved from that place and took my sleeping area apart. I moved where there is not TV or cell phone signals and it still did not happen. I had forgotten all about it after many years (5 to 10 years). then went to go visit friends back in civilization, it was about 100 miles from where I had formerly lived where I had the faraday cage set up. so, I slept at my friends place for the night. and got woke up at the same time on the clock with the same physical reaction. by the way, if I am awake at that time, there seems to be no effect that I can tell.
