Plain English Summary
French researchers exposed young rats to cell phone radiation (900 MHz) for five weeks and found disrupted sleep patterns, increased daytime eating, and impaired blood vessel function affecting temperature control. These changes suggest chronic RF exposure interferes with basic biological processes controlling energy use.
Why This Matters
This study reveals something particularly concerning about radiofrequency exposure during development. The researchers used 900 MHz radiation at 1 V/m, which is well within the range of everyday cell phone and wireless exposures. What makes these findings significant is that they demonstrate RF radiation can disrupt multiple interconnected biological systems simultaneously - sleep regulation, appetite control, and blood vessel function - all of which are critical for normal growth and development. The 42% increase in REM sleep episodes and the measurable changes in food intake aren't subtle effects you might dismiss as statistical noise. They represent substantial alterations in basic physiological processes. The fact that these changes occurred in developing animals is especially relevant, as children and adolescents may be more vulnerable to RF effects during critical growth periods when their biological systems are still maturing.

Study Details
We examined the effects of chronic RF-EMF exposure (900 MHz, 1 V m(-1)) on the main functions involved in body energy homeostasis (feeding behaviour, sleep and thermoregulatory processes).
Thirteen juvenile male Wistar rats were exposed to continuous RF-EMF for 5 weeks at 24 °C of air te...
We showed that the frequency of rapid eye movement sleep episodes was greater in the RF-EMF-exposed ...
Our results show that RF-EMF exposure can induce energy-saving processes without strongly disturbing the overall sleep pattern.
