Abstract

Overview

The systematic review assesses the impact of radiofrequency electromagnetic fields (RF-EMF) on self-reported symptoms. This follows increased usage of RF-EMF technology and health concerns communicated by the World Health Organization (WHO).

Objectives

The main objectives include evaluating the effects of RF-EMF exposure on non-specific symptoms and assessing the accuracy of individuals' perception of exposure.

Methodology

• Scope: Experimental studies involving the general public and individuals with idiopathic environmental intolerance attributed to EMF (IEI-EMF).
• Data sources: Extensive databases such as Medline and Cochrane Library, with searches up to April 2022.
• Analysis: Uses a meta-analysis approach with random effects and sensitivity analyses.

Findings

41 studies involving 2,874 participants reviewed, revealing:

• No significant effects of RF-EMF exposure on symptoms, supported by meta-analyses across various conditions and confidence levels.
• Inability of volunteers to recognize exposure status more accurately than chance.

Interpretation

Findings suggest that under regulatory limits, acute RF-EMF exposure does not cause symptoms. Symptoms noted in daily life might be due to perceived, not actual, RF-EMF exposure.

Conclusion

No evidence was found that supports an association between RF-EMF exposure and the occurrence of short-term reported symptoms or the detection capacity of individuals related to exposure. This challenges the role of symptoms as reliable indicators of underlying EMF conditions.

Prospects for Future Research

Future studies should aim for broader participant inclusion and standardized design protocols to enhance comparability and examine higher exposure levels.
