CDMA phone radiation showed no immediate effects on heart rate or breathing in people claiming electromagnetic sensitivity during controlled 30-minute exposures.

Plain English Summary

Summary written for general audiences

Researchers exposed 18 people who claimed electromagnetic hypersensitivity (EHS) and 19 healthy controls to both real and fake cell phone radiation from a CDMA phone for 30 minutes each. They measured heart rate, breathing rate, and heart rate variability to see if the radiation caused physical changes. The study found no measurable differences in any of these body functions between real and fake exposure in either group.

Study Details

The aim of this study is to investigate Physiological effects of RF exposure on hypersensitive people by a cell phone.

In this study, two volunteer groups of 18 self-declared EHS and 19 controls were exposed to both sha...

In conclusion, the RF exposure by a CDMA cellular phone did not have any effects on the physiological parameters for both groups.

Quick Questions About This Study

A 2008 study found CDMA cell phone radiation had no effect on heart rate variability in either electromagnetically sensitive people or healthy controls. Researchers measured heart rate, breathing rate, and heart rate variability during 30-minute real and fake exposures, finding no measurable differences between exposure conditions.
Research shows people claiming electromagnetic hypersensitivity cannot reliably detect CDMA cell phone radiation. A controlled study exposed 18 self-identified sensitive individuals to both real and fake cell phone signals, finding no physiological differences that would indicate detection ability during 30-minute exposure sessions.
CDMA cell phone radiation does not affect breathing rate in people with electromagnetic hypersensitivity, according to 2008 research. The study measured respiratory parameters in 18 self-identified sensitive people and 19 controls during real versus fake phone exposure, finding no significant changes in breathing patterns.
A 30-minute CDMA cell phone exposure produced no measurable physiological effects in electromagnetically sensitive people. Researchers monitored heart rate, breathing, and heart rate variability throughout the exposure period in both sensitive individuals and healthy controls, finding no time-dependent changes from the radiation.
Standard physiological tests including heart rate, respiratory rate, and heart rate variability measurements cannot detect CDMA cell phone radiation effects in electromagnetically hypersensitive people. A controlled study using these objective measures found no differences between real and fake 30-minute phone exposures in sensitive individuals.
