Effects of acute exposure to WIFI signals (2.45GHz) on heart variability and blood pressure in Albinos rabbit.

Saili L et al. · 2015

Researchers exposed rabbits to WiFi signals (2.45GHz) for one hour and measured their heart function and blood pressure. The WiFi exposure increased heart rate by 22% and blood pressure by 14%, while also disrupting normal heart rhythm patterns. This suggests that common WiFi radiation can directly affect cardiovascular function, even after just brief exposure.

The effects of long-term exposure to a 2450 MHz electromagnetic field on growth and pubertal development in female Wistar rats.

Sangun O, Dundar B, Darici H, Comlekci S, Doguc DK, Celik S · 2015

Researchers exposed pregnant and newborn female rats to WiFi-frequency radiation (2450 MHz) for one hour daily and tracked their development through puberty. Rats exposed in the womb showed slower growth, delayed puberty, and increased oxidative stress in brain and ovary tissues compared to unexposed controls. This suggests that WiFi radiation during critical developmental periods may disrupt normal reproductive maturation.

EMF radiation at 2450MHz triggers changes in the morphology and expression of heat shock proteins and glucocorticoid receptors in rat thymus.

Misa-Agustiño MJ et al. · 2015

Researchers exposed rats to 2.45 GHz radiofrequency radiation (the same frequency used in microwave ovens and WiFi) and found it caused visible damage to the thymus, a key immune system organ. The radiation triggered cellular stress responses, increased blood vessel leakage, and altered stress proteins even at levels below those that cause heating. This suggests that EMF exposure can disrupt immune system function through non-thermal biological mechanisms.

Structural and Ultrastructural Study of Rat Liver Influenced by Electromagnetic Radiation.

Holovská K et al. · 2015

Researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used by WiFi and microwave ovens) for 3 hours daily over 3 weeks at power levels of 2.8 mW/cm². They found liver damage including inflammation, blood vessel dilation, and cellular changes including fat accumulation and dying liver cells. This suggests that chronic exposure to common microwave frequencies may harm liver function.

Exposure to non-ionizing radiation provokes changes in rat thyroid morphology and expression of HSP-90

Misa-Agustiño MJ et al. · 2015

Spanish researchers exposed rats to 2.45 GHz radiation (the same frequency as Wi-Fi and microwave ovens) and found significant changes in thyroid gland structure. The radiation caused thyroid follicles to swell and shrink in different patterns depending on exposure duration and power levels. These structural changes suggest the thyroid gland was responding to radiation stress, raising questions about potential long-term effects on thyroid function in humans exposed to similar frequencies.

Long-term exposure to electromagnetic radiation from mobile phones and Wi-Fi devices decreases plasma prolactin, progesterone, and estrogen levels but increases uterine oxidative stress in pregnant rats and their offspring.

Yüksel M, Nazıroğlu M, Özkaya MO. · 2015

Researchers exposed pregnant rats to cell phone and Wi-Fi radiation for 60 minutes daily throughout pregnancy and tracked their offspring for multiple generations. They found that this exposure significantly decreased essential reproductive hormones (prolactin, estrogen, and progesterone) in both mothers and offspring, while increasing oxidative stress damage in the uterus. This suggests that everyday wireless radiation exposure during pregnancy could disrupt hormonal balance and reproductive health across generations.

Effects of Wi-Fi (2.45 GHz) Exposure on Apoptosis, Sperm Parameters and Testicular Histomorphometry in Rats: A Time Course Study.

Shokri S, Soltani A, Kazemi M, Sardari D, Mofrad FB. · 2015

Researchers exposed male rats to Wi-Fi radiation (2.45 GHz) for either 1 hour or 7 hours daily over 2 months to study effects on fertility. Both exposure groups showed decreased sperm quality, increased cell death in the testes, and reduced seminal vesicle weight compared to unexposed rats, with longer exposures causing more severe damage. This suggests that common Wi-Fi frequencies may harm male reproductive health in a dose-dependent manner.

Behavioral in-effectiveness of high frequency electromagnetic field in mice.

Salunke BP, Umathe SN, Chavan JG. · 2015

Researchers exposed mice to 2.45 GHz radiofrequency radiation (the same frequency used by WiFi and Bluetooth) for up to 120 days to see if it would cause anxiety, obsessive-compulsive behaviors, or depression-like symptoms. The study found no behavioral changes in the mice across multiple standard tests, even after four months of daily exposure. This suggests that chronic exposure to this common wireless frequency may not directly affect mood or anxiety-related behaviors.

Measurement of the dielectric properties of the epidermis and dermis at frequencies from 0.5 GHz to 110 GHz.

Sasaki K, Wake K, Watanabe S · 2014

Researchers measured how electromagnetic waves interact with the two main layers of human skin - the outer epidermis and deeper dermis - across frequencies from 0.5 to 110 GHz. They found that current safety models significantly underestimate how much electromagnetic energy these skin layers actually absorb, especially at higher frequencies above 20 GHz. This matters because accurate absorption data is crucial for both medical device development and safety assessments of wireless technologies.

Electromagnetic radiation (Wi-Fi) and epilepsy induce calcium entry and apoptosis through activation of TRPV1 channel in hippocampus and dorsal root ganglion of rats

Ghazizadeh V, Nazıroğlu M · 2014

Researchers exposed brain and nerve cells from epileptic rats to Wi-Fi radiation (2.45 GHz) for one hour and found it triggered additional calcium influx and cell death beyond what epilepsy alone caused. The Wi-Fi exposure activated specific calcium channels (TRPV1) that allowed harmful calcium to flood into neurons, leading to oxidative stress and programmed cell death. This suggests Wi-Fi radiation may worsen neurological conditions by overwhelming brain cells with calcium.

Increased DNA oxidation (8-OHdG) and protein oxidation (AOPP) by Low level electromagnetic field (2.45 GHz) in rat brain and protective effect of garlic.

Gürler HS, Bilgici B, Akar AK, Tomak L, Bedir A. · 2014

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.

Effect of a 2.45-GHz radiofrequency electromagnetic field on neutrophil chemotaxis and phagocytosis in differentiated human HL-60 cells.

Koyama S et al. · 2014

Japanese researchers exposed immune cells called neutrophils to 2.45-GHz radiofrequency radiation (the same frequency used in WiFi and microwave ovens) at levels up to 10 W/kg for up to 24 hours. They found no significant effects on the cells' ability to migrate toward threats or engulf harmful particles - two critical immune functions. This suggests that RF exposure at current safety limits may not impair these specific immune responses.

The in vivo effects of low-intensity radiofrequency fields on the motor activity of protozoa

Sarapultseva EI, Igolkina JV, Tikhonov VN, Dubrova YE · 2014

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.

Effects of melatonin on Wi-Fi-induced oxidative stress in lens of rats.

Tök L, Nazıroğlu M, Doğan S, Kahya MC, Tök O. · 2014

Researchers exposed rats to Wi-Fi radiation (2.45 GHz) for one hour daily over 30 days to study effects on eye lens health. They found that Wi-Fi exposure caused oxidative stress in the lens tissue, indicated by increased harmful byproducts and decreased protective antioxidant activity. However, when rats were given melatonin supplements, these negative effects were significantly reduced, suggesting melatonin may help protect eye tissue from Wi-Fi-related damage.

Effects of melatonin on Wi-Fi-induced oxidative stress in lens of rats

Tök L, Nazıroğlu M, Doğan S, Kahya MC, Tök O. · 2014

Turkish researchers exposed rats to Wi-Fi radiation (2.45 GHz) for one hour daily over 30 days and found it caused oxidative stress in the eye lens, similar to cellular damage from aging or toxins. When rats were given melatonin supplements, the antioxidant significantly reduced this Wi-Fi-induced damage. This suggests that common Wi-Fi exposure may harm delicate eye tissues, but natural protective compounds could help defend against such effects.

Researchers exposed mice to 2.45 GHz electromagnetic radiation (the same frequency used by Bluetooth devices) for up to 120 days to see if it would cause anxiety, obsessive-compulsive behaviors, or depression. The study found no behavioral changes in the mice at any time point, suggesting this level of EMF exposure did not affect their mental state or behavior patterns.

Wi-Fi (2.45 GHz)- and Mobile Phone (900 and 1800 MHz)-Induced Risks on Oxidative Stress and Elements in Kidney and Testis of Rats During Pregnancy and the Development of Offspring.

Ozorak A et al. · 2013

Turkish researchers exposed pregnant rats and their offspring to Wi-Fi (2.45 GHz) and mobile phone frequencies (900 and 1800 MHz) for one hour daily from pregnancy through 6 weeks of age. The exposed animals showed significant oxidative damage in kidneys and reproductive organs, with increased harmful byproducts and decreased protective antioxidants. This suggests that common wireless radiation may interfere with normal development and damage vital organs during critical growth periods.

Shahin S et al. · 2013

Researchers exposed female mice to 2.45 GHz microwave radiation (the same frequency as WiFi and microwave ovens) for 2 hours daily over 45 days at very low power levels. The exposed mice showed significantly reduced implantation sites for embryos, along with increased DNA damage in brain cells, elevated stress markers in blood, and disrupted hormone levels. This suggests that even low-level microwave radiation can interfere with reproduction and pregnancy through oxidative stress mechanisms.
