In this double-blind, placebo-controlled study, 106 patients with chronic insomnia were treated with the therapy for 20 minutes, three times per week for 12 weeks. EEG and other recordings were done before the first treatment and during the 12th (and last) treatment. There was a 26 % increase in total sleep time, and a significant reduction in the time taken for sleep onset, with the active therapy. No memory loss, mood change, daytime sedation, or hangover was observed. The authors of these studies postulate that the EMF affects the release of calcium from brain cells and this in turn affects the release of chemical transmitters in the brain, which may affect sleep patterns.
