Research Finds Effects of GSM Signals on Sleep

An anonymous reader writes "The effects of mobile phone radiation on sleep were studied in Sweden in a laboratory experiment where subjects were exposed either to 884 MHz GSM radiation or placebo. The study finds that compared to placebo, in the radiation-exposed subjects there was a prolonged latency to reach the first cycle of deep sleep (stage 3). The amount of stage 4 sleep was also decreased. Moreover, participants that otherwise have no self-reported symptoms related to mobile phone use, appear to have more headaches during actual radiofrequency exposure as compared to sham exposure."

    Well to an extent I did. I've been out in the middle of nowhere to the extent that you couldn't get a cell phone signal if your life depended on it (and sometimes it does!) and there is an odd sense of quiet.

    I know it sounds nuts but on a windy night even with the trees moving it still seems more quiet but in an almost impossible to define way. Like there is something that you can't put your finger on NOT there.

    I always thought it might be either radio singles or high pitch EM radiation from all the fun toys I have around it (yes, including a Wireless Router). So I'm not complaining, and I can sleep fine, but at the same time this study doesn't shock me at all.

    There could be any of a dozen causes keeping you up:
    • If you don't normally use an alarm clock but a specific need for one to wake up for a specific event, you were possibly preoccupied with the next day's event.
    • You may have had an uncomfortably strange lump under your pillow.
    • Were you at home, or on the road or in a hotel? Most people sleep "differently" when not in their own bed.
    • Does your phone emit an ultrasonic whine?
    • You might subconsciously be worried about the RF you believe you are exposing yourself to.
    • If you had a hand beneath the pillow while you slept, it might have made contact with the unfamiliar texture of the phone.
    There are a lot of very plausible reasons that don't involve a two-second-handshake-pulse-every-9-minutes, emitting a maximum of 600mW of RF energy near your head.

    You could try your own experiment -- have someone randomly set your phone to either "airplane mode" or "regular mode" while you continue to use it as an alarm clock. In the morning they'd have to restore your phone to regular mode so you wouldn't know which way you slept with it. They would record their settings while you recorded your sleep patterns. After a month or so, correlate the two and figure out if RF made any difference in your sleep.
