View Original AbstractThis study found no immediate blood pressure changes from mobile phone signals, but doesn't address long-term cardiovascular effects from chronic use.
Plain English Summary
Researchers tested 120 healthy volunteers to see if GSM and TETRA mobile phone signals caused immediate changes in blood pressure, stress hormones, or heart rhythm. Despite having enough statistical power to detect even tiny blood pressure changes (less than 1 mmHg), they found no effects from the phone signals. The study contradicted earlier research suggesting mobile phones could acutely raise blood pressure.
Why This Matters
This well-designed study with 120 participants represents important negative evidence in the EMF health debate. While the absence of acute cardiovascular effects from mobile phone exposure might seem reassuring, we need to interpret these findings carefully. The study examined immediate, short-term responses during brief exposure sessions, but didn't address the potential for cumulative effects from years of daily phone use. The reality is that most health concerns about mobile phones center on long-term, chronic exposure patterns rather than acute responses. What this means for you is that while your phone likely isn't causing immediate spikes in blood pressure during calls, this single study doesn't address the broader questions about sustained cardiovascular impacts from regular mobile phone use over months and years.
Exposure Information
Specific exposure levels were not quantified in this study.

The aim of this study is to investigate The effect of GSM and TETRA mobile handset signals on blood pressure, catechol levels and heart rate variability.

In light of this negative finding from a large study, coupled with two smaller GSM studies which have also proved negative, we are of the view that further studies of acute changes in blood pressure due to GSM and TETRA handsets are not required.
