One of the main advantages of WiFi is that it allows me to connect to an unlimited number of devices without any cords, making it an extremely convenient way to use the internet. However, it is important to note that there are significant safety concerns associated with this technology.

Aside from the risk of data theft, I am also concerned about the potential negative health effects of prolonged exposure to WiFi signals. In this guide, I will focus on the health concerns associated with WiFi radiation and provide tips on how to measure WiFi radiation levels in our own homes. I will also suggest effective ways to protect ourselves from this form of radiation, including the use of EMF protection products and shielding materials.

How WiFi Works

Wireless connectivity necessitates the utilization of three distinct devices: a router, a modem, and a receiver. While there can be multiple receivers, a typical network employs a solitary WiFi router and modem.

The modem establishes a wired connection to access the internet and then transfers the data via an ethernet cable to the wireless router. Subsequently, the WiFi router transmits the data through your home’s WiFi network, where it is intercepted by a receiver, such as the integrated one in your laptop computer. Once received, the data is decoded and made visible on your screen. Additionally, receivers can transmit data, which is collected by the WiFi router and sent back to the modem.

Throughout the years, WiFi has conformed to 802.11 networking standards, which have evolved to enable swifter data transfer rates. Currently, we employ 802.11ac, while the introduction of 802.11ax commenced in 2019. This newer iteration offers notably accelerated speeds.

Irrespective of the adhered standards, the signal emitted by your WiFi router and received by your device functions through radiofrequency transmission. WiFi signals generally operate within the 2.4GHz or 5GHz range, depending on your router. Within the electromagnetic spectrum, radiofrequency waves reside on the non-ionizing side, implying that unlike X-rays and ultraviolet light, they lack the energy required to atomize matter. Nonetheless, WiFi and other radiofrequency waves constitute a form of electromagnetic field (EMF) radiation.

Concerns of WiFi Radiation on Human Health

WiFi Router Radiation: How To Stay Protected

It’s important to be aware of the potential health risks associated with exposure to RF-EMF radiation. According to the World Health Organization, RF-EMF radiation is classified as possibly carcinogenic to humans, which is concerning. Although more research is needed, some studies have linked cell phone radiation to the development of gliomas in rats, a rare and deadly brain tumor. While WiFi radiation itself hasn’t been thoroughly studied, existing research suggests that it could be harmful. In fact, a 2017 literature review by researcher Martin L. Pall found that exposure to WiFi radiation was associated with various health effects, including DNA damage, neurological issues, alterations in sperm count and quality, cellular death, and effects on the endocrine system, among others. These findings are consistent with other research on RF-EMF radiation in general.

Moreover, exposure to WiFi radiation can also result in Electromagnetic Hypersensitivity (EHS) symptoms in sensitive individuals. While more research is needed on EHS, some sufferers claim that they are affected by the presence of WiFi radiation. Possible side effects of exposure in those with EHS include dizziness, nausea, headaches, and fatigue. It’s important to note that even those who aren’t sensitive to EMF radiation could still be at risk for negative health effects due to prolonged exposure.

Given the potential health risks associated with WiFi radiation, it is important to take proactive steps to protect ourselves and our families. This can include measures such as reducing WiFi use, turning off devices when not in use, and using airplane mode. Additionally, keeping a safe distance from WiFi devices and using wired connections can also help to minimize exposure to WiFi radiation.

How to Measure WiFi Radiation

TriField TF2

Detecting RF-EMF radiation emitted by your WiFi network can be accomplished using specific EMF meters. While any meter capable of detecting radio frequencies will suffice, we recommend considering the TriField TF2. However, if you do not possess a meter already, our comprehensive guide to The Best EMF Meters For Any Budget offers additional recommendations.

Once you have obtained your EMF meter, the subsequent step is to conduct the actual testing. Position yourself directly adjacent to your WiFi router and power off the device. Capture the initial reading using your EMF meter and take note of the results. Next, power on the WiFi router again and record another reading in the same location. Observe the disparity between the two measurements. It is beneficial to repeat this procedure at various distances from the router, including different rooms within your residence.

Furthermore, it is worthwhile to measure the readings near your WiFi-enabled devices, both with and without WiFi enabled. For instance, capture a reading next to your cell phone while it is connected to your home’s WiFi network, and then capture another reading at a similar distance with the phone’s WiFi turned off.

This exercise provides insight into the extent of WiFi radiation exposure for you and your family at home. Additionally, it helps identify specific devices that may require attention and offers potential solutions to address any concerns. If the radiation levels within your frequently used areas and bedrooms fall within the safe range, you might not need to take any further action. However, if unsafe radiation levels are detected in crucial areas of your home, it would be prudent to take appropriate measures.

Tips For Protecting Your Home

To mitigate WiFi radiation within your household, the most effective approach is transitioning to a completely wired network. Although this requires some effort, it offers distinct advantages. Firstly, it provides a more secure connection that is less susceptible to data breaches. Moreover, and particularly relevant to this topic, it virtually eradicates exposure to WiFi radiation.

Implementing simple lifestyle adjustments can also reduce overall WiFi exposure. These include turning off your home’s WiFi at night when it is not in use, and downloading games and media to your phone, tablet, or laptop so that they can be accessed without WiFi. If possible, it is advisable to avoid WiFi extenders as they expand the range of your WiFi signal, resulting in increased areas of WiFi radiation exposure. Instead, aim to limit the WiFi signal to a smaller coverage area.

Furthermore, it is worth considering that some WiFi radiation in your home may originate from your neighbor’s network. If this is the case, identify which areas of your home fall within the range of your neighbor’s WiFi signal. Then, apply EMF paint or use an EMF shielding barrier on the walls within that range to mitigate the impact of the radiation.
