So-called “mobile phone headache” due to radio frequency (RF) exposure is not a genuine phenomenon, say scientists. Their findings show that, although mobile phone use may produce headache, it is not a result of RF.
The experiment enrolled 17 individuals who experienced symptoms of mobile phone headache. In a cross-over design, they then used either mobile phones or sham phones. RF exposure from the mobile phones was also recorded.
“The increase in pain or discomfort (visual analogue scales) in RF sessions was 10.1 and in sham sessions 12.6.” In addition, “changes in heart rate or blood pressure were not related to the type of exposure.”
“The study gave no evidence that RF fields from mobile phones may cause head pain or discomfort or influence physiological variables. The most likely reason for the symptoms is a nocebo effect,” conclude the study’s authors.
