View Original AbstractRF-EMF exposure disrupted workers' natural daily heart and blood pressure rhythms, with stronger effects at higher exposure levels.
Plain English Summary
Researchers studied 61 workers exposed to radio frequency electromagnetic fields and found their natural daily blood pressure and heart rate patterns were disrupted - the normal peaks and valleys were flattened and shifted earlier, suggesting EMF exposure interferes with the body's cardiovascular rhythms.
Why This Matters
This study provides compelling evidence that radiofrequency EMF exposure can disrupt fundamental biological rhythms that regulate cardiovascular health. The science demonstrates that workers exposed to RF fields between 20-550 V/m experienced measurable alterations in their natural daily blood pressure and heart rate patterns. What makes this research particularly significant is that it shows dose-dependent effects - workers exposed to higher field strengths (200-550 V/m) experienced more pronounced disruptions than those exposed to lower levels (20-180 V/m). While these exposure levels are higher than typical consumer device emissions, they're not drastically different from what you might encounter near cell towers or Wi-Fi routers at close range. The reality is that our cardiovascular systems rely on precise circadian timing, and any interference with these natural rhythms could have long-term health implications that deserve serious attention.

Study Details
The aim of this study was to determine the course of diurnal rhythms of blood pressure and heart rate in a group of workers exposed to various intensities of radiofrequency electromagnetic fields.
In the study we used 61 healthy workers (aged 30-50 years) who had been exposed to radiofrequency EM...
Healthy men aged 28-49 years, working on a pattern of 12-24-12-48 h, exhibited typical, well-preserv...
Occupational exposure to radiofrequency EMF can result in changes of the diurnal rhythms of blood pressure and heart rate with lowering of their amplitudes and a shift of the acrophase. The clinical relevance of the present finding needs to be investigated in further studies.
