Researchers exposed rats to WiFi-frequency radiation (2.45 GHz) for one hour daily over 30 days and measured DNA damage in their brains and blood. The radiation caused significant genetic damage, indicated by increased levels of 8-OHdG (a marker of DNA oxidation) in both brain tissue and blood plasma. Interestingly, rats given garlic extract were protected from this DNA damage, suggesting antioxidants may help counter EMF-induced cellular harm.

Researchers exposed young rats to 50 Hz magnetic fields from power lines for 90 days and found significant brain damage from oxidative stress. Higher magnetic field levels caused more harm across multiple brain regions, including areas controlling memory and movement, suggesting potential neurological effects.
Ghodbane S1 et al. · 2014
Researchers exposed rats to static magnetic fields (128 mT) for one hour daily over five days and found the exposure disrupted glucose metabolism, increasing blood sugar levels by 21% and reducing liver energy storage. However, vitamin E supplementation prevented these metabolic disruptions, suggesting antioxidants may protect against magnetic field-induced metabolic damage.
Ciejka E et al. · 2014
Polish researchers exposed rats to 40 Hz magnetic fields at 7 mT (similar to some therapeutic magnetic devices) for either 30 or 60 minutes daily over two weeks. They found that both exposure durations significantly increased glutathione levels in skeletal muscle tissue compared to unexposed controls. Glutathione is the body's master antioxidant, so this suggests the magnetic fields triggered the muscles' natural defense systems against cellular damage.

Researchers exposed mouse embryonic cells to 50 Hz magnetic fields (the type from power lines) at 2 milliTesla for various time periods. They found that 6-hour exposures triggered autophagy, a cellular cleanup process, through increased reactive oxygen species (cellular stress molecules). This suggests that power frequency magnetic fields can alter fundamental cellular processes even at the cellular level.

Researchers exposed mice to 50 Hz magnetic fields (the same frequency as household electricity) for up to 120 days and measured anxiety-like behaviors. The magnetic field exposure significantly increased anxiety in the animals, and the researchers identified that this effect occurred through changes in NMDA receptors in the brain. The study provides biological evidence that long-term exposure to extremely low frequency magnetic fields can alter brain chemistry and behavior.
Manikonda PK et al. · 2014
Researchers exposed young rats to extremely low frequency magnetic fields (the type emitted by power lines and household appliances) for 90 days and found significant oxidative stress damage throughout their brains. The damage was dose-dependent, meaning higher magnetic field levels caused more harm, and affected different brain regions differently. This suggests that chronic exposure to these common magnetic fields may disrupt normal brain function by overwhelming the brain's natural defense systems.

Researchers exposed rats to extremely low frequency electromagnetic fields (1 and 5 Hz) for 21 days and measured changes in stress hormones and behavior. They found that these EMF exposures altered key stress hormones - increasing ACTH while decreasing noradrenaline - and changed glucose levels differently depending on frequency. The study demonstrates that even very low frequency electromagnetic fields can disrupt the body's stress response system.

Researchers exposed mice to 50 Hz electromagnetic fields (the same frequency used in power lines) for 4 hours daily over 28 days and found significant cognitive impairment and brain chemistry changes. The EMF exposure disrupted critical brain chemicals like glutamate and damaged important cellular pathways involved in memory formation. However, treatment with natural antioxidants from lotus seeds reversed these harmful effects, suggesting the brain damage was preventable.
Alsaeed I et al. · 2014
Researchers exposed pregnant mice and their newborn pups to 50 Hz magnetic fields (the same frequency as household electrical systems) during critical developmental periods. The exposed male mice later showed autism-like behaviors, including reduced social interaction and less interest in exploring new social situations, while their movement, coordination, and other basic functions remained normal. This suggests that magnetic field exposure during early brain development might contribute to autism spectrum disorders.

Turkish researchers exposed rats to mobile phone radiation at levels similar to everyday phone use for 4 weeks, then examined brain tissue for signs of programmed cell death (apoptosis). The exposed rats showed significantly increased levels of proteins that trigger cell death compared to unexposed controls. This suggests that mobile phone radiation may cause brain cells to die prematurely, even at the low power levels typical of normal phone use.

Researchers exposed single-celled organisms called ciliates to radiofrequency radiation at levels similar to what we encounter from cell phones and wireless devices. The radiation significantly reduced the organisms' ability to move, and this damage persisted in their offspring for at least 10-15 generations even though the offspring were never directly exposed. This suggests that RF radiation can cause biological effects that are passed down to future generations.

Researchers exposed mice to cell phone radiation (1800 MHz) for 30 days and found that 2-hour daily exposures significantly impaired learning and memory performance. The study also tested whether nano-selenium supplements could protect against these cognitive effects, finding that the supplement did help preserve brain function in radiation-exposed mice.
Qiao S et al. · 2014
Researchers exposed rats to microwave radiation for 5 minutes and found it impaired their spatial memory and learning abilities. The study revealed that this cognitive damage occurred because the radiation disrupted a key brain protein (phosphorylated synapsin I) that helps release GABA, a crucial neurotransmitter for brain function. This suggests that even brief microwave exposure can interfere with the brain's chemical communication system, potentially affecting memory and learning.
Pelletier A et al. · 2014
French researchers exposed young rats to cell phone radiation (900 MHz) for five weeks. The exposed rats slept 15.5% longer and preferred warmer temperatures than unexposed rats, suggesting radiofrequency radiation disrupts natural temperature control and sleep patterns.

Researchers exposed adolescent rats to cell phone radiation (900 MHz) for one hour daily over four weeks and found significant oxidative stress throughout the brain. The radiation increased harmful cellular damage markers and decreased protective antioxidants in key brain regions including the hippocampus, amygdala, and cerebellum. These biochemical changes coincided with altered behavioral performance, suggesting that cell phone radiation may impair brain function through oxidative damage.

Researchers exposed mice to cell phone-level radiofrequency radiation for 3 months and found significant reductions in brain proteins essential for neuron survival in auditory processing regions. This suggests chronic RF exposure at typical phone absorption rates may damage neurons responsible for hearing.
