Phone makers' own scientists discover that bedtime use can lead to headaches, confusion and depression
The people who had received the radiation took longer to enter the first of the deeper stages of sleep, and spent less time in the deepest one. The scientists concluded: "The study indicates that during laboratory exposure to 884 MHz wireless signals components of sleep believed to be important for recovery from daily wear and tear are adversely affected."
Critics have attacked the studies' methodology, but the new findings deal them a serious blow. For they show that the radiation did have an effect, even though people could not tell when they were exposed.
David Schick, the chief executive of Exradia, which manufactures protective devices against the radiation, called on ministers to conduct "a formal public inquiry" into the effects of mobile phones.
