Researchers exposed brain support cells called astrocytes to repetitive magnetic stimulation at different frequencies to see how they responded. They found that 1 Hz magnetic pulses caused a significant increase in calcium levels inside these cells, which is a sign of cellular activation. This suggests that magnetic fields can directly influence brain cells beyond just neurons, potentially explaining some of the biological effects seen with magnetic field exposure.

Researchers exposed 50 rats to 915 MHz radiofrequency radiation (similar to microwave ovens) at different power levels for 4 hours daily over one week, then tested whether this 'primed' their livers to better handle radiation damage. They found that low-power RF exposure increased protective antioxidant enzymes in the liver, creating an 'adaptive response' that helped protect against subsequent high-dose gamma radiation damage.

Researchers exposed onion roots to 2100 MHz cell phone radiation for 1-4 hours and measured cellular damage markers. The radiation triggered oxidative stress, causing harmful molecules called reactive oxygen species to build up while forcing the plant cells to work harder to defend themselves. This demonstrates that radiofrequency radiation can disrupt normal cellular function even in plant tissue.

Russian scientists exposed blood samples to high-frequency radiation (32.9-39.6 GHz) for 15 minutes and found neutrophils (infection-fighting white blood cells) responded more aggressively to bacterial threats. The enhanced immune response was caused by heating effects, showing electromagnetic radiation can amplify immune system activity.

Researchers exposed human cells to cell phone radiation (1800 MHz) for up to 60 minutes at typical phone power levels. The cells showed signs of oxidative stress, including increased harmful free radicals and elevated cellular defense responses, even without heating effects.
Calabrò E, Magazù S. · 2017
Italian researchers exposed proteins (including hemoglobin and albumin) to mobile phone radiation at 1750 MHz for 4 hours and measured changes in their molecular structure. They found that the proteins' alpha-helix structures physically aligned themselves with the electromagnetic field, causing measurable changes in their chemical bonds. This demonstrates that cell phone-level radiation can directly alter the shape and orientation of essential biological molecules.

Medina-Fernandez FJ et al. · 2017
Researchers used magnetic field therapy (similar to medical TMS treatment) on rats with an artificially induced multiple sclerosis-like condition. The 60 Hz magnetic fields at 0.7 milliTesla significantly reduced brain damage, improved motor symptoms, and decreased harmful oxidative stress. This suggests that controlled magnetic field exposure might have therapeutic potential for neurological conditions involving brain inflammation.
Kapri-Pardes E et al. · 2017
Scientists exposed eight cell types to extremely low frequency magnetic fields and found that even very weak fields (0.15 microtesla) triggered cellular responses by activating growth proteins. However, these responses were too small to cause cancer or cell damage, suggesting minimal health risk.
Marjanovic Cermak AM et al. · 2017
Scientists exposed cells to 1800 MHz radiation from cell phones for 10-60 minutes at typical usage levels. Even brief exposures triggered oxidative stress, where harmful molecules called free radicals increased faster than cells could neutralize them, indicating cellular damage pathways activated by phone radiation.

Researchers exposed brain cells from the hippocampus (a memory center) to 50-Hz magnetic fields at 2 milliTesla for 8 hours daily and measured various biological effects. They found that repeated exposure reduced cell survival and increased harmful reactive oxygen species, but did not cause DNA damage or cell death. The study suggests that while these magnetic fields create cellular stress, they may not cause severe biological damage.

Scientists exposed immune cells to 50 Hz magnetic fields from power lines at levels found near electrical devices. The magnetic fields damaged cellular energy centers, increased harmful free radicals, and triggered stress responses. This suggests everyday magnetic field exposure may stress our immune systems.
Naarala J et al. · 2017
Scientists exposed human blood vessel cells and rat brain cells to combinations of Earth's magnetic field and power line magnetic fields. They found that horizontal power line fields caused different cellular effects than vertical ones. This suggests power line magnetic fields may interact with Earth's natural field to influence cell behavior.
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.
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.

Researchers studied 57 stroke patients who received either standard rehabilitation alone or rehabilitation plus daily exposure to extremely low frequency magnetic fields (40 Hz) for four weeks. Patients exposed to the magnetic fields showed improved antioxidant enzyme activity in their blood and better functional recovery, including enhanced daily living skills and reduced depression scores compared to the control group.

Researchers exposed immune cells called macrophages to 50-Hz magnetic fields (the same frequency as power lines) for 24 hours to see if it would damage their DNA. They found that magnetic field exposure alone caused no harm, but when cells were first activated by bacterial toxins, the magnetic field exposure increased DNA damage and reduced cell survival.

Brazilian researchers reviewed 165 studies to examine whether cell phone radiation might cause or worsen tinnitus (ringing in the ears). They found that radiofrequency radiation from phones can penetrate ear tissues and cause biological effects, with some people being more sensitive to electromagnetic exposure. The review concluded there's reasonable evidence to suggest caution when using mobile phones to prevent hearing damage and tinnitus.
Siqueira EC et al. · 2016
Researchers analyzed saliva from the parotid glands (located near the jaw) in 83 people who regularly use cell phones, comparing the side exposed to phone radiation with the unexposed side. They found that the exposed side showed signs of inflammation, with decreased levels of an anti-inflammatory protein and increased levels of a pro-inflammatory protein. The inflammatory changes were more pronounced in people who had used cell phones for over 10 years, suggesting cumulative effects from long-term exposure.
Sagioglou NE et al. · 2016
Greek researchers exposed fruit flies to radiofrequency radiation at various frequencies (100-900 MHz) and found that all exposure protocols increased cell death in developing eggs, even at very low power levels. The study revealed that frequency-modulated signals caused more damage than continuous waves, and that biological effects don't follow a simple dose-response relationship. This research demonstrates that even brief exposures to RF radiation can disrupt normal cellular processes in developing organisms.
Grell K et al. · 2016
Researchers analyzed 792 brain tumor patients from 13 countries to see if gliomas (a type of brain cancer) occurred more often on the side of the head where people held their cell phones. They found a statistically significant pattern: brain tumors were more likely to develop on the same side of the head where patients reported using their phones most frequently. This spatial relationship held true regardless of how much time people spent on calls, suggesting that location of exposure may be more important than duration.

Researchers analyzed 27 studies examining how radiofrequency radiation (the type emitted by cell phones and wireless devices) affects male fertility. They found that 21 of the 27 studies showed harmful effects, with sperm swimming ability declining, DNA damage increasing, and cells producing more harmful reactive oxygen species. The evidence suggests RF radiation damages the cellular powerhouses (mitochondria) in sperm, leading to oxidative stress that impairs male reproductive health.
Kunt H et al. · 2016
Researchers studied electrical workers exposed to electromagnetic fields from high-voltage power lines and compared their health markers to unexposed workers. They found that electrical workers had lower bone density, disrupted thyroid function, and higher oxidative stress (cellular damage from harmful molecules). This suggests that long-term occupational EMF exposure may weaken bones and disrupt hormone production.

Russian researchers exposed single-celled organisms (protozoa) to cell phone frequency radiation (1 GHz) at very low power levels for 30 minutes to 6 hours. They found significant changes in cell shape and structure that correlated with reduced movement ability. The researchers suggest this method could help detect early cellular damage from mobile phone radiation, particularly effects on sperm cell mobility.
