Whole body exposure to 2.4 GHz WIFI signals: effects on cognitive impairment in adult triple transgenic mouse models of Alzheimer's disease (3xTg-AD).

Banaceur S, Banasr S, Sakly M, Abdelmelek H. · 2013

Researchers exposed mice with Alzheimer's-like symptoms to WiFi signals (2.4 GHz) for two hours daily over a month at levels similar to cell phone exposure. Surprisingly, the WiFi exposure actually improved cognitive performance and memory in the Alzheimer's mice compared to unexposed mice. This unexpected finding suggests radiofrequency radiation might have therapeutic potential for certain brain conditions, though the mechanism remains unclear.

Effects of olive leave extract on metabolic disorders and oxidative stress induced by 2.45 GHz WIFI signals.

Salah MB, Abdelmelek H, Abderraba M. · 2013

Researchers exposed rats to WiFi radiation (2.45 GHz) for one hour daily over 21 days and found it created a diabetes-like condition by damaging the body's natural antioxidant defenses in the liver and kidneys. The WiFi exposure reduced key protective enzymes by 33-68% and increased cellular damage markers by up to 51%. When researchers gave the rats olive leaf extract, it prevented most of the metabolic disruption and restored the protective enzymes, suggesting that WiFi radiation causes harm through oxidative stress.

They found that 10 hours of exposure led to 100% germination in just three days, compared to lower rates with shorter exposures. The study suggests microwave radiation can accelerate plant growth processes.

Aït-Aïssa S et al. · 2013

French researchers exposed pregnant rats and their newborns to WiFi signals (2450 MHz) for 2 hours daily during pregnancy and early life, then examined brain tissue for signs of stress and damage.

The study suggests that WiFi exposure during critical developmental periods may not cause detectable brain damage in rats.

Effect of in utero wi-fi exposure on the pre- and postnatal development of rats.

Poulletier de Gannes F et al. · 2012

French researchers exposed pregnant rats to Wi-Fi signals (2.45 GHz) for 2 hours daily during pregnancy to test whether this radiation could harm developing babies. They found no birth defects, developmental problems, or other harmful effects in the rat pups, even at the highest exposure level tested (4 W/kg). This study suggests that Wi-Fi exposure during pregnancy may not cause developmental harm at levels tested.

Exposure to 2.45 GHz electromagnetic fields elicits an HSP-related stress response in rat hippocampus.

Yang XS, He GL, Hao YT, Xiao Y, Chen CH, Zhang GB, Yu ZP. · 2012

Researchers exposed rats to 2.45 GHz electromagnetic fields (the same frequency as WiFi and microwave ovens) and found that their brain cells produced stress proteins in response. The hippocampus, a brain region crucial for memory and learning, showed increased levels of heat shock proteins (HSP27 and HSP70), which cells produce when they're under stress. This provides direct biological evidence that EMF exposure triggers a stress response in brain tissue.

2.45-Gz wireless devices induce oxidative stress and proliferation through cytosolic Ca²⁺ influx in human leukemia cancer cells.

Nazıroğlu M, Ciğ B, Doğan S, Uğuz AC, Dilek S, Faouzi D. · 2012

Researchers exposed human leukemia cancer cells to 2.45 GHz radiation (the same frequency used by WiFi and microwaves) for periods ranging from 1 to 24 hours. They found that this radiation caused cancer cells to multiply more rapidly and triggered harmful oxidative stress by allowing excess calcium to flood into the cells. The longer the exposure, the more pronounced these effects became.

Pathophysiology of microwave radiation: effect on rat brain.

Kesari KK, Kumar S, Behari J. · 2012

Researchers exposed young rats to 2.45 GHz microwave radiation (the same frequency used in WiFi and microwaves) for 2 hours daily over 45 days at power levels similar to many consumer devices. The exposed rats showed decreased melatonin production and increased markers of brain cell damage and death. This suggests that chronic exposure to common microwave frequencies may harm brain tissue and disrupt sleep-regulating hormones.

Ceyhan AM et al. · 2012

Researchers exposed rats to WiFi-frequency radiation (2.45 GHz) for one hour daily over four weeks and measured damage to skin tissue. The radiation significantly increased oxidative stress markers and decreased protective antioxidant enzymes in the skin. However, when rats were given beta-glucan (a natural compound found in oats and mushrooms) before each exposure, it largely prevented this cellular damage.

Solomentsev GY, English NJ, Mooney DA · 2012

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.

Prenatal exposure to radiofrequencies: Effects of WiFi signals on thymocyte development and peripheral T cell compartment in an animal model.

Laudisi F et al. · 2012

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.

Inhibitory Effects of Microwave Radiation on LPS-Induced NFκB Expression in THP-1 Monocytes.

Li CY, Liao MH, Lin CW, Tsai WS, Huang CC, Tang TK. · 2012

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.

Lu Y et al. · 2012

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.
