Plain English Summary
French researchers exposed volunteers to radiofrequency waves from mobile phones held against their jaw and ear for 20 minutes, measuring blood flow in skin capillaries. They found that phone radiation increased blood flow in tiny skin vessels more than sham exposure, even though skin temperature didn't change significantly. This suggests mobile phone radiation has specific biological effects on blood circulation that aren't simply due to heating.
Why This Matters
This study adds important evidence to the growing body of research showing that radiofrequency radiation from mobile phones produces biological effects beyond simple tissue heating. The fact that researchers observed increased blood vessel dilation without corresponding temperature changes challenges the telecommunications industry's long-standing position that RF effects are purely thermal. What makes this research particularly relevant is that it studied exposure conditions that mirror real-world phone use - holding a device against your head during calls. The vasodilatory response the researchers documented suggests your body is actively responding to RF exposure at the cellular level. While increased blood flow might sound benign, it indicates that biological processes are being altered by radiofrequency fields at power levels we encounter daily.
Exposure Information
Specific exposure levels were not quantified in this study.
