The myth that WiFi affects health is as old as the technology itself, but researchers from the University of Pennsylvania may have finally proved it wrong in a study which focused on claims that WiFi signals, but also other radio frequency (RF) signals, are harmful to human health.
An issue often cited by those who believe that RF exposure is harmful is “electromagnetic hypersensitivity,” which has never been confirmed or recognized by the scientific community. However, it has never been disputed in detail in the mainstream, despite the numerous important individual studies, itcbusiness.info reports.
The scientists from the University of Pennsylvania have now integrated all the previous findings with their own.
The notion that there are adverse health effects related to WiFi are problematic from the very start, as WiFi accounts for only 4% of all the RF signals surrounding us daily. Furthermore, in the 3,700 studies conducted as of 2018, no RF-related health problems were recorded, so it's clear that WiFi can't be harmful either.
As history shows, people are often apprehensive about new technologies, and transmitters, TC and utility poles, radio, TV and phones all caused similar fears when they first appeared.
The most widely cited document in favor of the position which says that RF signals are harmful is the BioInitiative Report, a nearly 1,500-page review of research on the biological effects of electromagnetic fields. The report, however, is considered to be strongly biased, excluding opposing views.
