Chronic exposure to 50Hz magnetic fields causes a significant weakening of antioxidant defence systems in aged rat brain.

This study reveals a troubling age-related vulnerability that has significant implications for our aging population. The 0.1 mT exposure level used here is well within the range of everyday magnetic field exposures - you can encounter similar levels near electrical panels, some appliances, or power lines. What makes this research particularly concerning is the clear demonstration that biological responses to EMF exposure change dramatically with age. While young organisms appear capable of mounting protective responses, older brains show a breakdown in their antioxidant defense systems when exposed to the same fields. The science demonstrates that EMF safety cannot be assessed using young, healthy subjects alone. Given that oxidative stress is already implicated in age-related neurological diseases like Alzheimer's and Parkinson's, these findings suggest that chronic magnetic field exposure could accelerate or worsen cognitive decline in older adults. This research adds important evidence to the growing body of literature showing that current safety standards, which focus primarily on heating effects, fail to account for the biological impacts that occur at much lower exposure levels.
