Abstract

Overview

This study examines the impact of mobile phone call duration on autonomic balance in healthy individuals.

Methodology

  • Participants: 30 healthy subjects aged 18-30, without systemic disease, regular mobile phone users for over five years, using a phone for a minimum of 30 minutes daily.
  • Tools: Heart rate variability (HRV) was measured using a three-channel physiograph with LabChart PROV8.1.8 and HRV Module version 2.0.3.
  • Measurement: HRV parameters recorded during baseline, during phone use, and post-phone use.
  • Parameters Analyzed: Including standard deviation of NN interval (SDNN), root mean square of successive differences (RMSSD), R-R intervals, mean heart rate, and other frequency domain parameters.

Findings

Among 30 participants, no significant arrhythmias were identified, but a notable difference was observed in pRR50 across the three measuring phases. Other parameters showed no significant variation.

Conclusion

While most parameters remained unaffected, mobile phone calls can potentially affect HRV and autonomic balance, possibly due to electromagnetic field exposure and the act of speaking. Such alterations could suggest a health risk associated with prolonged mobile phone usage.
