Evaluating the Effect on Heart Rate Variability of Adults Exposed to Radio-Frequency Electromagnetic Fields in Modern Office Environment

Abstract

Overview

The study aimed to determine whether heart rate variability (HRV) could effectively depict the potential effects of radio-frequency electromagnetic fields (RF-EMF) on humans in a modern office setting. The research focused on radiation levels at frequencies of 1.8 GHz (DECT) and 2.45 GHz (Wi-Fi), with exposure durations of 10 minutes and emitters placed 1 meter from the participants.

Findings

• HRV parameters analyzed included SDNN, RMSSD, LF, and HF.
• Sixty adults participated in three exposure runs, totaling 154 HRV recordings.
• Significant effects were identified for the SDNN parameter. In two runs, HRV changed between the control and exposure phases, while in another run, changes occurred from exposure to control phase.
• The cofactors smoking, coffee consumption, and the use of strong medications did not alter the observed EMF effects.

Conclusion

Heart rate variability appears to be a suitable measure to detect the influence of RF-EMF exposure on humans under certain study conditions. The study notes that prolonged exposure durations and the inclusion of higher frequencies such as 5G are necessary for a more detailed assessment of RF-EMF health impacts in contemporary office environments.

⚠️ This study identifies a connection between exposure to electromagnetic fields and measurable physiological changes in heart rate variability, underlining the importance of considering EMF safety in office environments.
