Researchers working on behalf of the mobile phone industry :rofl: have discovered that exposure to cell phone emissions can interfere with your sleep cycle.

Obviously, there is a need for more study, but the methodology, where a group of volunteers were exposed to either 884 MHz signals, or to a sham signal, seems to be a pretty good study format.

I am not sure if this was single, or double blind. (in the latter, the researchers don’t know who got the placebo either).

Definitive word to my mind:

Dr Chris Idzikowski, the director of the Edinburgh Sleep Centre, says: “There is now more than sufficient evidence, from a large number of reputable investigators who are finding that mobile phone exposure an hour before sleep adversely affects deep sleep.”
