Loughran SP, Wood AW, Barton JM, Croft RJ, et al. (2005)

Fifty participants (27 males) were exposed to electromagnetic fields from a cell phone for 30 minutes before sleep. The RFR exposure was from a GSM digital phone at 896.4 MHz frequency, which was pulsed. The SAR of the exposed hemisphere averaged over 10 g was 0.11 W/kg, with a peak value of 0.29 W/kg. The subjects also had a sham exposure, and the study had a randomized, double-blind, crossover design.

Results showed a decrease in REM sleep latency and increased EEG spectral power in the 11.5-12.5 Hz frequency range. The latter finding occurred during the initial part of the first non-REM sleep after exposure.
