View Original AbstractCell phone radiation at 2 watts showed no significant effects on heart rate control in healthy adults during short-term exposure.
Plain English Summary
Italian researchers exposed 26 healthy young adults to cell phone radiation at 900 MHz (2 watts) while measuring heart rate variability, which reflects how well the autonomic nervous system regulates heart rhythm. The study found no statistically significant effects on heart rate patterns during either rest or physical stress, though some minor changes were detected in a few measurements. This suggests that short-term cell phone exposure at typical power levels doesn't meaningfully disrupt the body's automatic control of heart function.
