Total antioxidant capacity, total oxidant status and oxidative stress index in the men exposed to 1.5 T static magnetic field.

Sirmatel O, Sert C, Sirmatel F, Selek S, Yokus B · 2007

Researchers exposed 33 men to the strong magnetic field from an MRI machine (1.5 Tesla) and measured markers of oxidative stress in their blood before and after exposure. Surprisingly, they found that the magnetic field actually reduced oxidative stress by increasing the body's antioxidant capacity and decreasing harmful oxidants. This suggests that short-term exposure to strong static magnetic fields may have protective rather than harmful effects on cellular health.

Affective response to 5 microT ELF magnetic field-induced physiological changes.

Stevens P · 2007

Researchers exposed people to extremely low frequency magnetic fields at 5 microTesla (similar to standing near some household appliances) pulsing at brain wave frequencies of 8-12 Hz. Participants reported changes in their emotional state during exposure, and brain measurements showed altered electrical activity patterns. This suggests that even relatively weak magnetic fields can influence both how people feel and measurable brain function.

Exposure to an additional alternating magnetic field affects comb building by worker hornets.

Ishay JS et al. · 2007

Researchers exposed worker hornets to weak 50 Hz magnetic fields (similar to power line frequency) for two weeks and found dramatic disruptions in their natural building behavior. The exposed hornets built 35-55% fewer cells, created deformed hexagonal structures, and produced more fragile comb stems compared to unexposed hornets. This demonstrates that even very low-level magnetic field exposure can interfere with complex biological processes that insects rely on for survival.

Pulsed radio-frequency electromagnetic fields: dose-dependent effects on sleep, the sleep EEG and cognitive performance.

Regel SJ et al. · 2007

Swiss researchers exposed 15 men to cell phone-like radiation at different intensities for 30 minutes before sleep, then monitored their brain activity and cognitive performance. They found that stronger radiation caused measurable changes in brain wave patterns during sleep and slowed reaction times on memory tasks. This demonstrates a dose-response relationship, meaning higher radiation exposure produces more pronounced effects on brain function.

Mobile phone 'talk-mode' signal delays EEG-determined sleep onset.

Hung CS, Anderson C, Horne JA, McEvoy P · 2007

Researchers exposed 10 healthy young adults to different mobile phone signal modes for 30 minutes, then measured how long it took them to fall asleep. They found that exposure to 'talk mode' signals significantly delayed sleep onset compared to listening mode or no signal exposure. The study suggests that the specific signal patterns phones emit during calls may interfere with the brain's natural transition to sleep.

Radiofrequency radiation (900 MHz) induces Egr-1 gene expression and affects cell-cycle control in human neuroblastoma cells.

Buttiglione M et al. · 2007

Researchers exposed human brain cells to 900 MHz radiofrequency radiation (the same frequency used by GSM cell phones) at power levels similar to what your phone emits. They found that this radiation activated stress response genes, disrupted normal cell division, and triggered cell death pathways. The effects occurred at radiation levels considered 'safe' by current standards, suggesting that RF exposure may interfere with fundamental cellular processes in brain tissue.

Gene expression analysis of ELF-MF exposed human monocytes indicating the involvement of the alternative activation pathway

Unknown authors · 2006

Researchers exposed human immune cells called monocytes to extremely low frequency magnetic fields (1.0 mT strength) and found significant cellular activation and gene expression changes. The study detected altered activity in 986 genes and identified specific immune pathway activation that could affect how our bodies respond to infections and inflammation.

Effects of pulsed electric fields on DNA of human lymphocytes

Unknown authors · 2006

Greek researchers exposed human immune cells (lymphocytes) to 50 Hz pulsed electric fields and found significant DNA damage compared to unexposed cells. The damage was detected using the comet assay, a sensitive test for DNA breaks. While some repair occurred after 2 hours, the findings show that power-line frequency electric fields can directly damage human genetic material.

42(12):1084-1088, 2006

Unknown authors · 2006

This 2006 commentary discusses considerations for conducting genome-wide association studies in Parkinson's disease research. The piece addresses methodological approaches for identifying genetic factors that may contribute to Parkinson's development. While not directly EMF-related, it provides context for understanding how genetic susceptibility research is conducted in neurodegenerative diseases.

Oxidative StressNo Effects Found107 citations

Radiat Environ Biophys

Unknown authors · 2006

German researchers exposed human blood cells from umbilical cords to 1,800 MHz cell phone radiation at 2 W/kg for up to 45 minutes, testing whether it triggers harmful reactive oxygen species or stress proteins. They found no meaningful biological effects - any statistical differences were due to lowered activity in control groups rather than increased damage from radiation.

Effect of short-wave (6-22 MHz) magnetic fields on sleep quality and melatonin cycle in humans: the Schwarzenburg shut-down study

Unknown authors · 2006

Researchers studied 54 people before and after a powerful radio transmitter was shut down in Switzerland, measuring sleep quality and melatonin levels. They found that stronger magnetic field exposure was linked to worse sleep and lower melatonin production, with improvements after the transmitter stopped operating. This unique real-world study provides evidence that radio frequency emissions can disrupt human sleep patterns and hormone cycles.

Occupational magnetic field exposure and melatonin: interaction with light-at-night

Unknown authors · 2006

Researchers studied 60 women exposed to extremely low-frequency magnetic fields at work and found that those exposed to both magnetic fields during the day and light at night had the lowest levels of melatonin (measured through urine). This suggests that workplace magnetic field exposure may make people more sensitive to the sleep-disrupting effects of nighttime light exposure.

Effects of 60-Hz magnetic field exposure on nocturnal 6-sulfatoxymelatonin, estrogens, luteinizing hormone, and follicle-stimulating hormone in healthy reproductive-age women: results of a crossover trial

Unknown authors · 2006

Researchers exposed healthy premenopausal women to 60-Hz magnetic fields (5-10 milligauss above background) for five nights and measured their hormone levels. The study found that magnetic field exposure significantly decreased nighttime melatonin production but did not affect reproductive hormones like estrogen or luteinizing hormone.

Consultations in primary care for symptoms attributed to electromagnetic fields--a survey among general practitioners

Unknown authors · 2006

Swiss researchers surveyed 342 general practitioners to understand how often patients seek medical help for symptoms they blame on electromagnetic fields. They found that 69% of doctors had seen at least one EMF-related patient, with sleep problems, headaches, and fatigue being the most common complaints linked to cell towers, power lines, and mobile phones. Doctors considered the EMF connection plausible in 54% of cases.

Electromagnetic hypersensitivity: biological effects of dirty electricity with emphasis on diabetes and multiple sclerosis

Unknown authors · 2006

This 2006 study examined how 'dirty electricity' (electrical pollution on power lines) affects health conditions like diabetes and multiple sclerosis. Installing filters to reduce this electrical pollution improved symptoms in diabetics (better blood sugar control) and MS patients (improved balance and mobility). The research suggests a connection between increasing electromagnetic pollution and rising rates of chronic diseases.

The prevalence of symptoms attributed to electromagnetic field exposure: a cross-sectional representative survey in Switzerland

Unknown authors · 2006

Swiss researchers surveyed over 2,000 people to understand how many experience electromagnetic hypersensitivity (EHS) and worry about EMF health effects. They found 5% reported symptoms they attributed to EMF exposure, with sleep problems and headaches being most common, while 53% expressed concern about EMF health risks without experiencing symptoms themselves.

Childhood leukemia and residential magnetic fields: are pooled analyses more valid than the original studies?

Unknown authors · 2006

This 2006 commentary examines whether combining multiple studies on childhood leukemia and power line magnetic fields produces more reliable results than individual studies alone. The authors discuss the validity and limitations of pooled analyses that attempt to determine if residential magnetic field exposure increases childhood leukemia risk.

Effect of short-wave (6-22 MHz) magnetic fields on sleep quality and melatonin cycle in humans: the Schwarzenburg shut-down study

Unknown authors · 2006

Swiss researchers studied 54 people before and after a powerful radio transmitter was shut down, measuring sleep quality and melatonin levels. They found that stronger magnetic fields from the transmitter correlated with worse sleep and lower melatonin production, with improvements occurring after shutdown. This unique natural experiment provides compelling evidence that radio frequency emissions can disrupt human sleep patterns and hormone cycles.

Growth assessment of children exposed to low frequency electromagnetic fields at the Abu Sultan area in Ismailia (Egypt)

Unknown authors · 2006

Researchers studied 780 Egyptian children aged 0-12 years, comparing those living within 50 meters of high-voltage power lines to a control group. Children exposed to power line EMF showed significantly reduced height, head circumference, and chest circumference at all ages, plus delayed bone development. This suggests chronic exposure to low-frequency electromagnetic fields may impair normal childhood growth and development.

Occupational magnetic field exposure and melatonin: interaction with light-at-night

Unknown authors · 2006

Researchers studied 60 women exposed to magnetic fields at work and found that those exposed to both workplace magnetic fields and nighttime light had the lowest levels of melatonin (measured through urine). The combination of daytime magnetic field exposure and nighttime light exposure appears to suppress melatonin production more than either exposure alone.

Childhood leukemia and magnetic fields in Japan: a case-control study of childhood leukemia and residential power-frequency magnetic fields in Japan

Unknown authors · 2006

Japanese researchers studied 312 children with leukemia and 603 healthy controls, measuring magnetic field levels in their bedrooms from power lines and electrical sources. Children exposed to magnetic fields of 0.4 microTesla or higher showed 2.6 times higher risk of leukemia overall, and 4.7 times higher risk specifically for acute lymphoblastic leukemia. This large study adds to growing evidence linking household magnetic field exposure to childhood cancer risk.
