A study of mobile phones and their impact on human health was recently conducted by researchers from Wayne State University in Detroit and the Karolinska Institute in Sweden. The results of the study surprise. Mobile phone use before bedtime can lead to headaches, insomnia, tiredness in the morning and in general may reduce the amount of deep sleep, which means a stress for the whole body.
Mobile Phones May Cause Insomnia, Headaches and Aggressiveness
35 men and 36 women aged from 18 to 45 took part in the study. Some of them received the radiation that was equivalent to that received from using a cell phone. Others were exposed to “sham” radiation. For those, who had received the real radiation, it took longer to enter the first of the deeper stages of sleep. At the same time they spent less time in the deepest stage, than those not exposed to radiation. The study found, that the use of cell phones before bedtime might disrupt sleep because of the radiation from it.
Using mobile phones is associated with specific changes in the areas of the brain responsible for controlling the stress system. So, using them before bedtime can cause insomnia, headaches, aggressiveness and confusion. The radiation from a mobile phone may reduce the amount of deep sleep, which means a stress for the body, because it is not able to refresh itself properly. This is why it is recommended to switch off the mobile phones at night and not to use it before sleep.
