The claims made by some, including a British radio DJ, that Wi-Fi sensitivity or electrosenstivity affects 2% of the population has been exposed to be a PR stunt to promote the DJ’s latest album, Electrosensitivity.
Claims that say the condition does exist have yet be substantiated with medical evidence. The 2% figure is unfounded and all of the cases that have been reported have been proven to be psychosomatic cases. Cases have been disproven with blind studies that showed that those who claimed to be sensitive to Wi-Fi signals could not tell when a Wi-Fi signal was being broadcast.
The part of the spectrum which is used by Wi-Fi signals is not unique to the standard. Electromagnetic waves of the same type are common place in nature and any person that is affected by Wi-Fi signals would not be able to live a normal life without getting sick. Wi-Fi signals are also low energy signals unlike those used by microwaves, cell phones and Bluetooth.
