Researchers exposed mice to magnetic fields from power lines for one hour daily over two weeks. The exposure caused hyperactivity and altered brain chemistry in areas controlling movement and reward, with changes lasting up to a year, suggesting these fields can permanently affect brain function.

Researchers exposed adult rats to 50-Hz magnetic fields (the same frequency as power lines) for either 1 or 4 hours daily over 4 weeks. They found that rats exposed for 4 hours showed increased anxiety-like behaviors but also improved spatial learning and long-term memory. This suggests that extremely low frequency magnetic fields can affect both emotional and cognitive brain functions, even at relatively short daily exposure periods.
Garaj-Vrhovac V et al. · 2011
Croatian researchers studied marine radar operators exposed to microwave radiation and found significant DNA damage and cellular stress compared to unexposed workers. The exposed group showed doubled genetic damage markers and clear oxidative stress, providing evidence that occupational microwave exposure causes measurable harm to human cells.

Researchers exposed mice to 2.45 GHz microwave radiation (the same frequency used in WiFi and microwave ovens) for 2 hours daily over 30 days. The exposed mice showed disrupted sleep patterns, increased blood cell counts, DNA damage in brain cells, and impaired spatial memory compared to unexposed mice. This study suggests that chronic exposure to common wireless frequencies may affect brain function and biological rhythms.
Jorge-Mora T et al. · 2011
Spanish researchers exposed rats to 2.45 GHz microwave radiation (the same frequency as WiFi and microwave ovens) and measured brain activity in a region called the hypothalamus that controls stress responses. They found that both single and repeated exposures triggered significant increases in cellular activation markers, with repeated exposure causing more than double the brain activity compared to unexposed animals. The effects occurred at power levels that didn't heat tissue, suggesting the brain responds to microwave radiation through non-thermal mechanisms.
Masuda H et al. · 2011
Researchers exposed rat brain tissue and human cells to 50-Hz magnetic fields at 1 milliTesla (similar to levels near power lines) to see if this affected serotonin receptors, which are important for brain function and mood. They found no changes in how serotonin bound to these receptors or in the cellular responses that follow. This suggests that magnetic field exposure at this level doesn't interfere with this particular brain signaling pathway.

Italian researchers exposed newborn mice to WiFi-like signals (2.45 GHz) for 5 weeks during early development to see if young immune systems are more vulnerable to wireless radiation. They found essentially no effects on immune system development at either low (0.08 W/kg) or high (4 W/kg) exposure levels, with only one minor change in male mice at the higher level. The study suggests that developing immune systems may not be as sensitive to WiFi radiation as some have theorized.

Researchers exposed brain immune cells called microglia to 2.45 GHz radiofrequency radiation (the same frequency used in WiFi and microwave ovens) for 20 minutes at high intensity. They found that this EMF exposure triggered inflammation in the brain cells by activating a specific molecular pathway called JAK2-STAT3, which led to increased production of inflammatory chemicals. This suggests that EMF exposure may contribute to brain inflammation through well-defined biological mechanisms.
Croft RJ et al. · 2010
Scientists tested how 2G and 3G cell phone signals affect brain waves in 103 people of different ages during 55-minute exposures. Only young adults showed brain wave changes from 2G signals, while teenagers and elderly showed no effects, suggesting age influences brain sensitivity to phone radiation.
Croft RJ et al. · 2010
Researchers exposed 103 people across three age groups (teens, young adults, and elderly) to 2G and 3G cell phone signals while measuring their brain waves. They found that only young adults (ages 19-40) showed changes in their alpha brain waves when exposed to 2G signals, while teenagers and elderly participants showed no effects from either 2G or 3G exposure. This suggests that brain sensitivity to cell phone radiation varies significantly by age.

Researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used in WiFi routers and microwave ovens) for 2 hours daily over 35 days at relatively low power levels. They found significant DNA damage in brain cells, disrupted antioxidant defenses, and changes in proteins that regulate cell division. The authors concluded this chronic exposure pattern may promote brain tumor development.
Vecchio F et al. · 2010
Italian researchers measured brain wave patterns in elderly and young adults while exposed to cell phone radiation for 45 minutes. They found that older adults showed significantly increased synchronization between the left and right brain hemispheres in the alpha frequency range (8-12 Hz) during phone exposure, while younger subjects showed minimal changes. This suggests that aging brains may be more vulnerable to electromagnetic field effects from mobile devices.

Researchers exposed rats to magnetic fields used in medical therapy to test heart effects. Thirty minutes daily caused no harm, but sixty minutes significantly increased cellular damage and reduced natural antioxidants. This shows exposure duration matters more than field strength for heart health.

Researchers exposed rats to magnetic fields at safety-approved levels for 10 months. Even these "safe" exposures caused brain cell damage and reduced natural antioxidant defenses. This suggests current safety standards may not adequately protect against long-term biological harm.
Martínez-Sámano J et al. · 2010
Researchers exposed rats to strong 60 Hz magnetic fields for two hours and found decreased antioxidants in their hearts and blood. These antioxidants normally protect cells from damage, suggesting that even brief exposure to powerful magnetic fields can weaken the body's natural cellular defenses.

Researchers exposed immune cells to 50 Hz magnetic fields (power line frequency) while they fought bacterial infections. The magnetic field exposure boosted the cells' bacteria-fighting ability by increasing nitric oxide production and protective proteins. This suggests some EMF exposures might enhance rather than harm immune function.
Sambucci M et al. · 2010
Italian researchers exposed pregnant mice to WiFi signals (2.45 GHz) for 2 hours daily during pregnancy to study effects on birth outcomes and immune system development in offspring. They found no differences in pregnancy success, birth weight, or immune function (specifically B-cells that produce antibodies) when offspring were tested at 5 weeks and 26 weeks of age. This suggests that prenatal WiFi exposure at these levels may not significantly impact reproductive outcomes or immune system development.

Turkish researchers exposed leukemia cells to 50 Hz magnetic fields for different time periods. A single one-hour exposure decreased cell maturation, but daily exposure for four days increased it. This shows EMF timing can produce opposite biological effects in the same cells.
Grigoriev YG et al. · 2010
Russian researchers exposed rats to microwave radiation at levels similar to what cell phones emit (2450 MHz frequency) for 7 hours daily over 30 days. They found the radiation triggered immune system changes in brain tissue, causing the body to produce antibodies against its own brain cells. This suggests that even low-level microwave exposure may cause autoimmune reactions where the immune system mistakenly attacks healthy tissue.
Hao Y, Yang X, Chen C, Yuan-Wang, Wang X, Li M, Yu Z · 2010
Researchers exposed brain immune cells called microglia to 2.45 GHz radiation (the same frequency used in WiFi and microwave ovens) for 20 minutes and found it activated these cells through a specific cellular pathway called STAT3. The activated microglia began producing inflammatory molecules including nitric oxide and tumor necrosis factor-alpha. This matters because microglial activation is linked to brain inflammation and neurological problems.
Ravera S et al. · 2010
Italian researchers exposed brain cell membranes to 50 Hz magnetic fields (the same frequency as electrical power lines) and found that a key enzyme called acetylcholinesterase was reduced by 27%. This enzyme is crucial for proper nerve signaling in the brain. The effect occurred at magnetic field levels of 0.74 milliTesla and was completely reversible when the exposure stopped.
Ravera S et al. · 2010
Researchers exposed brain tissue to 50 Hz magnetic fields (power line frequency) and found it reduced activity of a key brain enzyme by 27%. This enzyme controls nerve communication for memory and learning, suggesting power-frequency fields can disrupt basic brain chemistry.

British researchers used computer modeling to calculate how much radiofrequency energy (called SAR) a 10-year-old child's body would absorb from Wi-Fi devices operating at typical household distances. They found that Wi-Fi exposure produced SAR levels of 3.99-5.7 milliwatts per kilogram in the child's torso and head, which is less than 1% of what a cell phone produces. This study provides important baseline data on children's Wi-Fi exposure levels.

Researchers exposed brain immune cells called microglia to 2.45 GHz electromagnetic fields (the same frequency used in WiFi and microwaves) and found that this radiation activated inflammatory pathways in the cells. The EMF exposure triggered specific molecular changes that led to increased production of inflammatory proteins and nitric oxide. This matters because activated microglia contribute to brain inflammation, which is linked to neurological problems and brain diseases.
Hirose H et al. · 2010
Researchers exposed brain immune cells called microglia to cell phone radiation at levels up to 2.0 W/kg for two hours to see if it would activate an inflammatory response. They found no signs of activation or increased production of inflammatory molecules compared to unexposed cells. This suggests that moderate levels of cell phone radiation don't trigger brain inflammation in laboratory conditions.
