According to a study conducted by scientist from Karolinska Institute and Uppsala University in Sweden, and in Wayne State University, cell phones give out radiation that can interfere people's ability to sink into deep sleep. The researchers subjrcted to radiation 35 men and 36 women, aged 18 to 45. Half of the subjects were exposed to 884-megahertz wireless signals, in which radiation is similar to those emitted by cell phones. The other half of the subjects got no radiation.
Results showed those subjects exposed to radiation took longer to enter deep stage of sleep than those who were not exposed to radiation. The study was founded by cell phone makers Mobile Manufacturers Forum, who reported the findings as "inconclusive." But the lead man in the study, Bengt Arnetz, a Swedish professor declared that cell phones "have measurable effects on the brain." He said " the radiation from phones activates the brain's stress system, making people feel more alert and decreasing their ability to wind down and snooze."
Arnetz further added, "And bear in mind, when you're talking in the phones, there is a mental stimulus from the conversation itself, in addition to the radiation. The combination makes it doubly hard to relax into deep sleep."
