Even people claiming electromagnetic hypersensitivity couldn't detect or respond to cell phone radiation at levels higher than typical phone use.

Plain English Summary

Summary written for general audiences

Researchers tested whether people claiming electromagnetic hypersensitivity (EHS) could actually detect cell phone radiation or experience symptoms from it. They exposed 17 EHS subjects and 20 healthy controls to real and fake WCDMA phone signals for 32 minutes while monitoring heart rate, breathing, and symptoms. Neither group showed any physiological changes or could reliably tell when they were being exposed to real radiation.

Study Details

The aim of this studies Is to invesitgate Effects of radiation emitted by WCDMA mobile phones on electromagnetic hypersensitive subjects.

In this double-blind study, two volunteer groups of 17 EHS and 20 non-EHS subjects were simultaneous...

WCDMA RF-EMFs generated no physiological changes or subjective symptoms in either group. There was n...

Considering the analyzed physiological data, the subjective symptoms surveyed, and the percentages of those who believed they were being exposed, 32 min of RF radiation emitted by WCDMA mobile phones demonstrated no effects in either EHS or non-EHS subjects.

Quick Questions About This Study

A 2012 study found no evidence that cell phone radiation causes symptoms in people claiming electromagnetic hypersensitivity. Neither EHS subjects nor healthy controls showed physiological changes or could detect when exposed to real WCDMA phone signals for 32 minutes.
Research shows 3G WCDMA phone radiation doesn't affect people who claim electromagnetic sensitivity differently than others. A controlled study found no physiological changes, symptoms, or ability to detect radiation exposure in either sensitive or non-sensitive individuals.
No, WCDMA radiation from mobile phones doesn't affect heart rate or breathing patterns. Researchers monitored these vital signs during 32-minute exposures and found no physiological changes in either electromagnetically sensitive people or healthy controls.
Studies on 1950 MHz WCDMA radiation show no measurable health effects during typical exposure periods. Research found no physiological changes, symptoms, or detection ability in both electromagnetically hypersensitive individuals and healthy people after 32-minute exposures.
Mobile phone EMF doesn't impact people claiming electromagnetic sensitivity any differently than others. Controlled testing revealed no physiological responses, subjective symptoms, or ability to perceive radiation exposure in either sensitive or non-sensitive groups.
