One of the greatest conveniences of today is being able to use a cell phone while travelling in a car, even without having to touch the device. Most people are not aware, however, that this exposes the body and brain to excessive amounts of microwave frequencies. Long term over-exposure to these frequencies have been proven to be harmful, but are even more so when travelling in a well-insulated, steel chamber like a car.
An excellent case study by the University of Mainz in Germany showed the effects of this radiation, with an Electroencephalogram (EEG). They were able to measure the electrical activity of the driver's brain and the effects are disturbing to say the least. According to the researchers, "the brain is clearly under more stress" as this exposure "results in large scale activation in all areas of the brain, which can affect the ability to concentrate and general fitness to drive." They go on to say that, "In the worst case, the increased long term stress on the brain can lead to symptoms similar to burnout, irritability, exhaustion, and tiredness."
Many people in Gauteng spend at least 2-4 hours per day travelling in cars with cell phones and bluetooth constantly emitting microwave frequencies. To lessen these effects, you should avoid using the cell phone in the car, keep it on "Airplane/Flight Mode," and switch off the vehicle's wireless network. This is especially important while travelling long distances.
Personally, for the last 2 years, when travelling by car, my wife and I usually keep our devices on Flight Mode, and we have noticed that we feel noticeably less fatigued while driving and have more energy upon reaching our destination.
I encourage you to do an experiment for yourself and see if you notice a difference.
