The influence of the call with a mobile phone on heart rate variability parameters in healthy volunteers.

This study adds important evidence to our understanding of how cell phone radiation affects the autonomic nervous system, which controls involuntary functions like heart rate, breathing, and digestion. The researchers found measurable changes in heart rate variability during phone calls that reversed afterward, suggesting a direct biological effect rather than just psychological stress from conversation. What makes this particularly significant is that heart rate variability is considered a key marker of cardiovascular health and autonomic nervous system function. While the authors acknowledge that speaking itself might contribute to these changes, the pattern of effects strongly suggests EMF influence on the nervous system's control of heart function. The reality is that these findings align with a growing body of research showing that cell phone radiation can affect autonomic nervous system balance, even at exposure levels considered safe by current regulations.
