Dasdag S, Akdag MZ, Kizil G, Kizil M, Cakir DU, Yokus B. After studying these effects, Hertel concluded that microwaving food leads to food degeneration. [83] found that long-term exposure to microwave radiation (typical mobile phone, at an SAR level range of 0.170.37W/kg for 3h daily for 8months, or wireless digital enhanced cordless telecommunications/telephone (DECT) base at an SAR level range of 0.0120.028W/kg for 8h/d for 8months) induced the synthesis of 143 proteins, including some neuronal function-associated proteins such as glial fibrillary acidic protein (GFAP), glial maturation factor (GMF), apolipo protein E, heat-shock protein, cytoskeletal proteins and some proteins that are associated with metabolism in the brain. Effects of fetal microwave radiation exposure on offspring behavior in mice. Numerous mechanisms can activate oxidative stress, including electromagnetic radiation, and thereby cause molecular damage. It has also been reported that acute exposure to continuous waves of 900MHz EMF or 900MHz waves that were modulated to an amplitude of 50Hz increased reactive oxygen species (ROS) levels and DNA fragmentation as a result of the hyperstimulation of glutamate receptors [73].

It has been reported that microwave radiation can induce lipid peroxidation of cell membranes and produce apoptotic signals [74, 75]. Article To investigate whether exposure of rat brains to GMS microwaves induced DNA breaks and changes in gene expression, Belyaev et al. 2015;91:42634. In the probe test, the exposed group could not locate the platform and exhibited a significantly higher mean latency (i.e., 3-fold higher) to reach the target quadrant, and they spent only half the time that the controls spent in the target quadrant. One of the bad impacts a microwave has on humans, is that some of the acids in the food people put in the microwave, gets transformed into a type of acid which turns poisonous. Microwaves are widely used in broadcasting, communications and many industrial fields. Vorobyov et al. Wang et al.

Symptoms included headache, paresthesia, diarrhea, malaise and lassitude. A resting eyes-closed electroencephalogram was used to continuously record the results, which showed that there was an increase in the power of the , 1 and 2 frequency bands in the 0.303W/kg group and in the 2 frequency bands in the 0.003W/kg group. However, Li et al. It has been reported that microwave radiation can decrease both the number and the density of dendritic spines [63]. 2023 BioMed Central Ltd unless otherwise stated. Is nuclear respiratory factor 2 a master transcriptional coordinator for all ten nuclear-encoded cytochrome c oxidase subunits in neurons? The direct cause of the observed neuronal damage may have been apoptosis induced by the microwave radiation, and an indirect cause may have been an increase in permeability of the blood-brain barrier (BBB), which would allow the traversal of toxic substances that could cause damage. Each Wi-Fi exposure and restraint occurred for 2h/d during gestation until parturition. as it have a harmful side. Vakalopoulos C. The EEG as an index of neuromodulator balance in memory and mental illness. For example, people who have used mobile phones for more than 10years have a clearly higher risk of brain tumors.

[111] found that the rate of glucose metabolism in the brains of rats was lower after short-term exposure to microwave radiation, and the blood glucose management reduced the damage that was caused by microwave radiation due to the decreased glucose uptake (2.45MHz, 1mW/cm2, continuous radiation for 30 d at 3h/d), as were learning and memory capacity. Gibson GE, Jope R, Blass J. Based on this background, in this review, we first summarized the effects of microwave radiation on the central nervous system, including the epidemiology, morphology, electroencephalograms, learning and memory abilities and mechanisms of underlying brain dysfunction from the perspective of synaptic structures and functions, oxidative stress and apoptosis, protein synthesis, genes and individual susceptibility and energy metabolism. Cookies policy. Schmid MR, Murbach M, Lustenberger C, Maire M, Kuster N, Achermann P, et al. The results showed that 2.1GHz W-CDMA-modulated microwave radiation did not cause apoptotic cell death but altered cell cycle progression [79]. 2017;326:291. SAR Value There are guidelines internationally for short term exposure to cell phone frequency microwaves, defined in terms of the Specific Absorption Rate (SAR), the rate at which energy is absorbed by the human body when exposed to radio frequency radiation. [40] also repeated the experiment only and found that radial-arm maze performance in rats remained unchanged. [68] radiated Wistar rats with microwaves (30mW/cm2; SAR value, 14.1W/kg), and then detected the expression of synaptic vesicle-associated proteins and found that synaptophys in I and VAMP-2, which are synaptic fusion proteins, and synaptic vesicle proteins were abnormally expressed to different degrees. ranging from as long as one meter to as short as one. Ann N Y Acad Sci. Microwave radiation can cause tissue damage by inducing localized microstructural damage to proteins [86, 87]. With the increasing number of applications that use microwave technology, its negative effects on the human body have attracted attention. 2004;25:4957. [63] exposed rat hippocampal neurons to microwaves (SAR values of 0.8W/kg and 2.4W/kg at an average power density of 1800MHz/d) and observed the formation of dendritic filopodial and dendritic branches and the maturation of dendritic spines in neurons from day 6 to 14. Alterations of cognitive function and 5-HT system in rats after long term microwave exposure. In the group treated with 0.8W/kg, there was no significant change. To investigate the potential combined influence of maternal restraint stress and 2.45GHz Wi-Fi signal exposure on postnatal development and behavior in the offspring of exposed rats, control, Wi-Fi-exposed, restrained and both Wi-Fi-exposed and restrained groups were established. In summary, there is evidence that microwave radiation can lead to alterations in protein synthesis or protein modifications; however, the results are controversial. Cobb BL, Jauchem JR, Adair ER. 2012;35:32534. their effects on the human body are vastly different: - Non-ionizing Radiation Frequency range: 0.1 - 1013 Hz .

Indian J Occup Environ Med. The experimental rats were divided into six groups of 3 adult rats and 3 young rats in each group (with control, GSM alone and call-receiving subgroups in each group). An increasing level of acetylcholine can increase the concentration of free calcium ions in synapses, but its concentration was decreased by 60% after exposure to microwave irradiation [117].

Therefore, the authors concluded that exposure to a radiofrequency of 900MHz might trigger the neoplastic process because it produces a relative increase in the number of potentially long-lived cells. Concurrently, the discovery that microwaves have positive biological effects has presented new challenges for research and applications in this field. Lymphatic Systems: Due to chemical alterations within food substances, malfunctions occur in the lymphatic system, causing a degeneration of the body's ability to . More than 50% of miRNAs are found in cancer-associated regions of the genome or in fragile sites, suggesting that miRNAs also play important roles in the pathogenesis of neoplasias [96]. Particularly, the dramatically increasing number of mobile phones users rise significant concerns due to its potential damage on people exposed by radiofrequency waves. Wang et al.
