View Original AbstractThirty days of magnetic field and power-frequency EMF exposure caused weight loss and liver stress in mice, indicating potential health risks from everyday electrical exposures.
Plain English Summary
Researchers exposed mice to magnetic fields and 50 Hz electromagnetic fields (the type from power lines) for 30 days to study health effects. The exposed mice lost weight and showed signs of liver stress, including increased oxidative damage (cellular damage from unstable molecules) and changes in blood chemistry. The study suggests that prolonged exposure to these common electromagnetic fields may disrupt the body's ability to protect itself from cellular damage.
Why This Matters
This research adds to growing evidence that extremely low frequency electromagnetic fields - the type emitted by power lines, household wiring, and electrical appliances - can trigger biological stress responses even at non-thermal levels. What makes this study particularly relevant is that 50 Hz EMF is the standard electrical frequency used throughout most of the world (60 Hz in North America), meaning these findings relate directly to everyday exposures in our homes and workplaces. The researchers documented clear signs of oxidative stress, which occurs when the body's natural antioxidant defenses become overwhelmed. This is significant because oxidative stress is linked to numerous health conditions including accelerated aging, cardiovascular disease, and neurological disorders. While the study doesn't specify exact exposure levels, the consistent pattern of biological disruption across multiple body systems suggests our current safety standards may not adequately protect against chronic, low-level EMF exposure.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: SMFs + 50 Hz ELF-EMF Duration: 30 days
Study Details
We investigated the effects of continuous whole body exposure to both fields for 30 days on some liver and blood parameters in mice.
Two exposure systems were designed; the first produced a gradient SMF while the second generated uni...
The results showed a gradual body weight loss when mice were exposed to either field. This is couple...
The results indicate that there is a relation between the exposure to SMF or ELF-EMF and the oxidative stress through distressing redox balance leading to physiological disturbances.
