NEWSBRIEF - Mobile phones affect sleep patterns.
Swiss researchers report that using a mobile phone before going to bed can detrimentally affect the quality of sleep. The researchers exposed 16 volunteers to electromagnetic radiation on one side of their head for 30 minutes before going to bed. The radiation was designed to simulate that emitted from a mobile phone. The researchers found that the volunteers had a disturbed sleep pattern (non-REM sleep) for as much as 50 minutes after being exposed to the radiation. They conclude that "a short exposure to electromagnetic fields emitted by mobile phones has an effect on brain physiology".
