This study analyzed cellular stress levels in rat thymus after exposure to a 2.45 GHz radio frequency (RF) using an experimental diathermic model in a Gigahertz Transverse Electromagnetic (GTEM) chamber. The thymus tissue presented several morphological changes, including increased distribution of blood vessels along with the appearance of red blood cells and hemorrhagic reticuloepithelial cells, while the glucocorticoid receptors presented greater immunomarking on the thymic cortex in exposed animals. These results indicate that non-ionizing sub-thermal radiation causes changes in the endothelial permeability and vascularization of the thymus, and is a tissue-modulating agent for Hsp90 and GR.
The present study was performed to investigate the effect of 2.45 GHz microwave radiation (2 h/day for 35 days) on reproductive pattern of male Wistar rats. Chronic exposure to these radiations produced formation of apoptotic cells in testis. In addition, a significant decrease in the levels of antioxidant enzymes glutathione and superoxide dismutase activities as well as an increase in catalase activity was observed in the exposed group. These results indicate that a low level exposure of microwave radiations exerts a negative impact on male reproductive system function.
This article is not correct. Wifi waves are just a low frequency sound wave. Everyone is having a placebo effect, or doing the equivalence of listening to music using ear buds all night by having the router too close to their heads. This article was made to play on your fears and to have you buy products like iPad radiation shields and other junk. This article is harmful to people.
METHODS: Standard class V cavities were prepared on the buccal surfaces of 20 non-carious extracted human premolars. The teeth were randomly divided into 2 groups (n = 10). The control group was stored in non-environment. The specimens in the experimental groups were exposed to a radiofrequency radiation emitted from standard Wi Fi devices at 2.4 GHz for 20 min. The distance between the Wi-Fi router and samples was 30 cm and the router was exchanging data with a laptop computer that was placed 20 m away from the router. The concentration of mercury in the artificial saliva in the groups was evaluated by using a cold-vapor atomic absorption Mercury Analyzer System. The independent t test was used to evaluate any significant differences in mercury release between the two groups.
With that in mind, several school districts in the U.S. and other countries have tried to reduce exposure in the classroom to RF radiation from devices. The Maryland State Department of Education, for example, recommended in 2016 that school districts use wired networks instead of WiFi whenever possible, turn off routers when not being used, and keep routers as far away from students as possible. In France, WiFi is banned from nursery schools.
Of course, trying to avoid radio wave exposure is more or less impossible if you live in modern society. Moskowitz advises keeping wireless devices away from your body and turning off wireless networks when they’re not in use. While any health risks are still theoretical, “I think trying to minimize exposure is the best advice at this point,” Moskowitz adds.
However, wireless routers are typically located significantly farther away from users' heads than a mobile phone the user is handling, resulting in far less exposure overall. The Health Protection Agency (HPA) says that if a person spends one year in a location with a Wi-Fi hotspot, they will receive the same dose of radio waves as if they had made a 20-minute call on a mobile phone.[7]
“If you're looking for ways to limit your exposure to the electromagnetic emissions from your cell phone, know that, according to the FTC, there is no scientific proof that so-called shields significantly reduced exposure from these electromagnetic emissions. In fact, products that block only the earpiece—or another small portion of the phone—are totally ineffective because the entire phone emits electromagnetic waves. What's more, these shields may interfere with the phone's signal, cause it to draw even more power to communicate with the base station, and possibly emit more radiation.”
Electromagnetic Fields (EMF) are invisible. You can’t see, touch, or feel them, but doesn’t mean they’re not there. As awareness about possible negative effects of wireless energy grows, curiosity simultaneously rises. More and more people ask me about how far they need to be and where the optimal placement is of their routers are for they’re health and safety.
TRPV1 cation channels are the possible molecular pathways responsible for changes in the hormone, oxidative stress, and body temperature levels in the uterus of maternal rats following a year-long exposure to electromagnetic radiation exposure from mobile phones and Wi-Fi devices. It is likely that TRPV1-mediated Ca2+ entry in the uterus of pregnant rats involves accumulation of oxidative stress and opening of mitochondrial membrane pores that consequently leads to mitochondrial dysfunction, substantial swelling of the mitochondria with rupture of the outer membrane and release of oxidants such as superoxide (O2 −) and hydrogen peroxide (H2O2). The superoxide radical is converted to H2O2 by superoxide dismutase (SOD) enzyme. Glutathione peroxidase (GSH-Px) is an important antioxidant enzyme for removing lipid hydroperoxides and hydrogen peroxide and it catalyzes the reduction of H2O2 to water.

The device comes in a variety of forms ranging from the $39 Aries Shield ("a silicon based micro processor that ... decomposes oscillations of electromagnetic fields") to the $249 Aires Defender Utility (which "has two next generation 9 core silicon based micro processor (sic) that provide universal protection from electromagnetic smog of the broadband frequencies").
One thing I am totally shocked by is the resistance that people seem to have to believing that something that promotes “Convenience” for them, could be dangerous. I am Electromagnetic Hypersensitive and I am involved with numerous groups of people worldwide who are suffering from the detrimental effects of wireless radiation. These groups are growing substantially as people become more and more aware that their health issues can be traced back to consistent exposure to microwave radiation that has NO proven record or research to prove its safety. From my own experience, placed in a Wi-Fi field, every muscle in my body contracts like I’m being electrocuted, lumps begin to form from the effect of blood thickening, I get massive headaches, chest pain (the heart struggling due to sticky red blood cells), and eventually total paralysis from the severe fatigue that even makes it hard to breath. So many people are suffering from illnesses they haven’t even traced back to Wi-Fi but if they succeed at globalizing it, I’m sure you’ll all find out eventually as you accumulate the effects. Thank you Dr Edward Group for posting this invaluable information.

Nevertheless, a group of scientists got together in the mid-2000s, calling themselves the BioInitiative Working Group. This group, which largely consisted of wireless radiation researchers, has written a harsh reply as feedback to the reports claiming that posed no health risks.  The reply lists a wide range of health effects scientists at the European Commission have unfortunately either ignored or dismissed.
