Researchers used computer simulations to study how 2.45 GHz microwave radiation (the same frequency used in WiFi and microwave ovens) affects protein structure at the molecular level. They found that electromagnetic fields disrupted the normal folding patterns of proteins by interfering with hydrogen bonds that keep proteins stable. This suggests that microwave radiation can alter fundamental biological processes by changing how proteins maintain their shape and function.

French researchers exposed pregnant rats and their newborn pups to Wi-Fi signals (2.45 GHz) for two hours daily during pregnancy and early life, then tested the young rats' blood for immune system markers and signs of developmental problems. They found no changes in immune responses or reproductive development at any exposure level tested, including levels much higher than typical human exposure to Wi-Fi.

Italian researchers exposed pregnant mice to WiFi signals (2.45 GHz) at high levels for 2 hours daily throughout pregnancy to study effects on their offspring's immune system development. They found no detrimental effects on T cell development, immune cell counts, or immune function in the offspring at either 5 weeks or 26 weeks of age. This suggests that prenatal WiFi exposure may not harm developing immune systems, though the study used exposure levels much higher than typical human exposure.

Researchers exposed immune cells (monocytes) to 2450 MHz microwave radiation - the same frequency used in microwave ovens and Wi-Fi - and found it suppressed their normal inflammatory response. When these cells were stimulated to trigger inflammation, microwave exposure reduced their production of NFκB, a key protein that regulates immune function. This suggests microwave radiation can interfere with your immune system's ability to respond properly to threats.

Researchers measured radiofrequency radiation from cell towers, radio, and TV stations across 65 locations in Palestine. FM radio stations produced the highest exposure levels at 62% of total radiation. All measurements remained well below international safety limits, providing important baseline data for urban RF exposure.

Researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used by WiFi and microwave ovens) for 3 hours daily over 30 days at very low power levels. The radiation caused significant memory and learning problems, and the rats' brain cells had trouble absorbing glucose, which is essential for brain function. However, when researchers gave the rats extra glucose, it reversed the memory problems.
Nazıroğlu M et al. · 2012
Researchers exposed rats to 2.45 GHz radiation (the same frequency used in WiFi and microwave ovens) for one hour daily over 30 days and found it caused brain damage including increased calcium levels in neurons, oxidative stress, and abnormal brain wave patterns. However, when rats were given melatonin supplements, these harmful effects were significantly reduced, suggesting melatonin may protect against WiFi radiation damage to the brain and nervous system.

Researchers exposed rats to WiFi-frequency radiation (2.45 GHz) for 30 minutes and found it triggered cellular stress responses in thyroid tissue. Heat shock proteins dropped significantly within 90 minutes, though recovered by 24 hours, demonstrating that brief microwave exposure can disrupt normal thyroid cell function.

Researchers exposed male rats to WiFi-frequency radiation (2.45 GHz) for one hour daily over 28 days and found significant damage to sperm-producing cells in the testicles. The radiation reduced the number of hormone-producing Leydig cells, impaired sperm production quality, and triggered programmed cell death (apoptosis) in testicular tissue. This suggests that common wireless frequencies could potentially affect male fertility through cellular damage in reproductive organs.

Researchers exposed male rats to 2.45 GHz microwave radiation (the same frequency used in WiFi and microwave ovens) for 2 hours daily over 60 days and found significant damage to reproductive function, including reduced testosterone and increased cellular stress markers. However, when they also exposed the rats to low-frequency pulsed electromagnetic fields, this treatment appeared to counteract much of the microwave damage. The study suggests that while microwave radiation can harm male fertility, certain types of electromagnetic therapy might offer protection.

Researchers exposed human brain cells (glial cells) to 2.45 GHz radiofrequency radiation at power levels up to 10 times higher than current safety limits for up to 24 hours. They used advanced genetic analysis to look for changes in how genes were expressed, but found no significant alterations. This suggests that even at high exposure levels, this type of RF radiation may not directly damage the genetic machinery of brain cells.
Sakurai T et al. · 2011
Japanese researchers exposed human brain cells (glial cells) to 2.45 GHz radiofrequency radiation at various power levels for up to 24 hours and examined whether this changed gene activity. Using advanced genetic analysis techniques, they found no significant changes in how genes were expressed in the exposed cells compared to unexposed controls. This suggests that RF radiation at these levels did not trigger detectable genetic responses in this type of brain cell.

Researchers exposed rats to 2.45-GHz radiation (the same frequency used by WiFi and microwaves) for one hour daily over 28 days and found it caused oxidative stress in heart tissue. The radiation increased harmful lipid peroxidation and depleted protective vitamins A, C, and E in the heart. When rats were given selenium or L-carnitine supplements, these antioxidants significantly reduced the radiation-induced damage.
Türker Y et al. · 2011
Researchers exposed rats to 2.45-GHz radiation (the same frequency used by Wi-Fi and microwaves) for one hour daily over 28 days and found it caused oxidative stress in heart tissue. The study showed that supplements selenium and L-carnitine could partially protect against this damage by reducing harmful free radicals and supporting the body's natural antioxidant defenses. This suggests that common wireless frequencies may stress cardiovascular tissue at the cellular level.
Papageorgiou CC et al. · 2011
Researchers exposed 30 people to Wi-Fi signals while they performed a mental task that required focus and working memory, measuring brain activity through electrodes on the scalp. They found that Wi-Fi exposure significantly reduced brain activity (measured by P300 brain waves) in men but not women during tasks requiring mental inhibition. This suggests Wi-Fi radiation may impair attention and working memory functions differently based on gender.

Nigerian researchers measured radiofrequency radiation levels around cell phone towers and broadcast antennas in Lagos City to assess public safety. They found power density levels ranging from 0.219 to 302.4 milliwatts per square meter, which were 20 to 50 times below international safety limits set by ICNIRP and IEEE. The study concluded that people staying at least 6 meters away from these antennas face minimal health risks from RF exposure.

Researchers modeled how electromagnetic radiation from cell phones and WiFi (at 900, 1800, and 2450 MHz) is absorbed differently by eyes with common vision problems like nearsightedness and farsightedness. They found that the structural differences in these eyes create more complex patterns of energy absorption compared to normal eyes. This suggests people with vision disorders may experience different levels of electromagnetic exposure to their eye tissues.
Chaturvedi CM et al. · 2011
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.
Sambucci M et al. · 2011
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.

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.
