Plain English Summary
German researchers exposed 40 healthy young adults to mobile phone radiation (900 MHz) for specific periods while measuring blood pressure, heart rate, and stress hormones. While participants' blood pressure increased by about 5 mmHg during the testing protocol, this increase occurred equally during both real and fake (placebo) exposures. The study found no evidence that mobile phone radiation affects cardiovascular function or the nervous system that controls blood pressure.
Why This Matters
This study represents a well-designed investigation into one of the most concerning potential health effects of mobile phone use - impacts on cardiovascular function. The researchers used proper controls and measured multiple parameters including stress hormones like norepinephrine and cortisol. However, the 5 mmHg blood pressure increase observed in both exposure and placebo conditions suggests the effect was likely due to the experimental procedure itself rather than EMF exposure. What this means for you: while this particular study found no cardiovascular effects from 900 MHz radiation, it examined only acute exposure in healthy young adults. The reality is that real-world mobile phone use involves chronic, repeated exposures over years or decades, often in people with existing health conditions - scenarios this study didn't address.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 900 MHz, pulsed with 217 Hz Duration: 20 min of supine rest, 10 min of 70° upright tilt on a tilt table, and another 20 min of supine rest
Study Details
The present study investigated the hypothesis, based on the results of our previous study, that exposure to EMFs can increase sympathetic vasoconstrictor activity.
Forty healthy young males and females underwent a single-blind, placebo-controlled protocol once on ...
Similar to the previous study, systolic and diastolic blood pressure each showed slow, continuous, s...
These findings do not support the assumption of a nonthermal influence of EMFs emitted by mobile phones on the cardiovascular autonomic nervous system in healthy humans.
