It is found that the mild radiation that a brain receives from a cell phone can cause a person to have problems falling asleep. A study also found that people that were exposed to mobile phone radiation just before trying to go to sleep had higher risks when it came to having insomnia and headaches. The same people also had more trouble reaching a state of deep sleep and they couldn’t stay in deep sleep as long as people who weren’t being exposed to cell phone radiation.
It is assumed that mobile phone radiation causes changes in the areas of the brain responsible for activating and coordinating the stress system. It is recommended not to talk on a cell phone soon before going to bed.
