Dr. Mercola says that about 2 percent of the population is supersensitive to the electromagnetic fields Wi-Fi produces, although some reports estimate the victims as high as 5 percent. The fact that increasing numbers of hotels, airports, bars, and coffee shops are adding wireless Internet makes shopping, going out for a drink, or taking a vacation more difficult.
Even though electromagnetic signals aren’t new — cell phones and televisions emit them, too — Wi-Fi electromagnetic waves are higher in frequency and stronger because of the immense amount of information they carry. Symptoms also can include headaches, fatigue, depression, sleep disturbances, irritability, panic attacks, arthritic-like pain, heart palpitations, memory problems, and rashes.
The electromagnetic fields also can affect neurological tissues, and experts fear they could contribute to Alzheimer’s, multiple sclerosis, and Parkinson’s disease.
Although there’s no cure for the problem, a handheld electromagnetic meter can alert victims when they are entering a Wi-Fi area.
