Researchers exposed rats to 60-Hz magnetic fields (the same frequency as household electricity) and found that this exposure caused DNA breaks in brain cells. However, when the rats were given melatonin or another antioxidant compound before exposure, these protective substances completely blocked the DNA damage. This suggests that magnetic fields may damage DNA through free radical formation, and that antioxidants might offer protection.

Researchers exposed mice to magnetic fields from power lines during sleep to test effects on their internal body clocks. The magnetic fields caused only minor changes in movement, while light exposure significantly disrupted sleep hormones. Power line magnetic fields don't appear to disrupt circadian rhythms.

Researchers exposed mice to magnetic fields from power lines for 25 days, then tested their memory using mazes. Long-term exposure impaired the mice's ability to recognize new environments, suggesting that prolonged exposure to common household magnetic fields may interfere with spatial memory abilities.

Researchers exposed rats to 120 Hz magnetic fields and found the fields made brain blood vessels leaky and dilated. This suggests EMF exposure might weaken the blood-brain barrier, which normally protects the brain from harmful substances in the bloodstream.
Gutiérrez-Mercado YK et al. · 2013
Researchers exposed rats to extremely low frequency magnetic fields (120 Hz at 0.66 mT) and found that these fields increased blood vessel permeability in specific brain regions called circumventricular organs. The magnetic field exposure caused blood vessels to dilate and become more permeable to substances that normally can't cross into brain tissue. This suggests that ELF magnetic fields can compromise the brain's protective blood barrier system.

Researchers exposed rats to 10 Hz magnetic fields for 15 days to study brain chemistry effects. Three hours of daily exposure decreased serotonin breakdown products in the brain's mood-regulating region, while one hour had no effect. This suggests magnetic fields can alter brain chemistry linked to mood.

Researchers tested whether transcranial magnetic stimulation (TMS) using 60 Hz magnetic fields at 0.7 mT could help treat an animal model of multiple sclerosis. They found that TMS reduced brain inflammation and oxidative stress (cellular damage from unstable molecules) more effectively than standard pharmaceutical treatments. This suggests magnetic field therapy might have protective effects on the nervous system.
Medina-Fernandez FJ et al. · 2017
Researchers exposed rats with multiple sclerosis-like symptoms to magnetic field stimulation (0.7 mT at 60 Hz) for 2 hours daily over 3 weeks. The magnetic field treatment significantly reduced brain and spinal cord damage, improved motor symptoms, and decreased harmful oxidative stress while boosting protective antioxidant systems. This suggests that certain types of electromagnetic field exposure may actually have therapeutic benefits for neurological conditions.

Researchers exposed rats with Huntington's disease-like symptoms to extremely low-frequency electromagnetic fields (60 Hz at 0.7 milliTesla) for 21 days. The EMF exposure improved the rats' neurological function, increased protective brain proteins, and prevented nerve cell death in the brain region most affected by Huntington's disease. This suggests that specific types of EMF exposure might have therapeutic potential for neurodegenerative diseases.
Tasset I et al. · 2012
Researchers exposed rats with a Huntington's disease-like condition to 60 Hz electromagnetic fields at 0.7 milliTesla (similar to standing very close to power lines) for 4 hours daily over 21 days. The electromagnetic field exposure significantly protected brain cells from damage, reduced harmful oxidative stress, and preserved neurons that would otherwise die from the disease. This suggests that certain types of electromagnetic fields might have therapeutic potential for neurodegenerative diseases.

Coballase-Urrutia E et al. · 2018
Researchers exposed stressed laboratory animals to weak static magnetic fields (0.8 mT) for varying durations over 5 days and measured markers of cellular damage called oxidative stress. They found that magnetic field exposure significantly reduced harmful oxidative stress markers while boosting the body's natural antioxidant defenses. The protective effects were time-dependent, suggesting that controlled magnetic field exposure might help the body cope with stress-related cellular damage.
Kim SJ et al. · 2017
Researchers exposed immune cells called macrophages to 60 Hz magnetic fields at 0.8 mT (similar to power line frequencies) and found the fields significantly increased inflammatory responses. The EMF exposure boosted production of inflammatory molecules like nitric oxide and cytokines, while also reducing the effectiveness of antioxidants that normally help control inflammation. This suggests that everyday electromagnetic field exposure might make our immune cells more prone to chronic inflammation.

Turkish researchers exposed laboratory rats to 50 Hz magnetic fields (the same frequency as power lines) for 50 and 100 days to measure DNA damage. They found that exposed rats had significantly more oxidative DNA damage and cellular damage markers compared to unexposed rats, with the damage increasing over time. This suggests that long-term exposure to power-frequency magnetic fields may cause cumulative genetic damage at the cellular level.

Researchers exposed lab-grown nerve cells with ALS-related genetic mutations to 50 Hz magnetic fields (the same frequency as power lines) for up to 72 hours. They found that while the magnetic field didn't kill cells or increase oxidative stress, it disrupted iron metabolism genes specifically in cells with the SOD1G93A mutation linked to familial ALS. This suggests that power frequency magnetic fields may interfere with cellular iron regulation in genetically susceptible individuals.
