Overview

The purpose of this study was to explore the immediate impact of electromagnetic waves (EMW) emitted by mobile phones on the cognitive performance, particularly attention and concentration, of emergency physicians.

Methodology

This investigation was structured as a single-center, prospective, randomized, double-blinded clinical trial conducted at a tertiary hospital. It involved thirty emergency physicians who underwent initial evaluations using the d2 attention and concentration test. Participants were divided into two groups:

• The control group used mobile phones turned off near their ears for 15 minutes.
• The experimental group had their phones turned on and held to their left ears for the same period, exposing them to 900-1800MHz EMW.

Attention levels were assessed again after the intervention using the d2 test.

Findings

Results indicated no significant differences in overall performance changes or fluctuations in attention between the control and experimental groups. However, parameters related to selective attention showed statistically significant improvements in the group exposed to EMW, suggesting a potential positive impact on certain aspects of cognitive function.

Conclusion

Contrary to widespread concerns, our findings suggest that short-term exposure to EMW from mobile phones may not hinder, and could enhance, selective attention capacities in emergency healthcare professionals. Such findings highlight the need for further research into the nuanced effects of EMW on human health and cognitive functions.
