Ever since the increase in mobile phone usage in recent years, there has been a growing concern about the effects of exposure to cell phone electromagnetic radiation on human health. A recent study which involved 35 men and 36 women, half of whom were exposed to mobile phone radiation for 3 hours and half of whom believed they had not been exposed (Placebo group). In a sleep session started 1 hour later, those who had been exposed to radiation took longer to reach the first cycle of sleep and spent less time in deep sleep, than the placebo group. The results suggest that exposure to cell phone radiation may have an impact on sleep cycles, which may in turn lead to insomnia.
