So that's why I'm so tired. And I thought it was putting my head in the microwave.

New research shows that the electromagnetic signals emanating from mobile phones can alter your brainwaves. Indeed, the latest studies suggest that mobile phone transmissions can even affect behavior. In one study, scientists from the Swinburne University of Technology monitored the brainwaves of folks with Nokia phones, er, strapped to their heads. They noticed that the cell phone transmissions boosted alpha waves. In a separate experiment, researchers from the Loughborough University Sleep Research Centre observed that sleep-deprived subjects with phones on their heads showed a dampening of delta waves that are markers of sleep. For hours after the phones were turned off, the test subjects exhibited difficulty falling asleep.
