Many people are now enjoying the convenience of using Wi-Fi networks in public places such as coffee shops, airports, and hotels. Wi-Fi hotspots are easy to use and provide a high-speed data connection to the Internet. However, they are not free from the risk of exposing users to possible health hazards.
What are the risks?
Users of public Wi-Fi can be exposed to many health hazards including viruses, unwanted calls, and even identity theft. The same risks apply to mobile device users who use the internet through mobile networks.
Possible health risks caused by public Wi-Fi
Most of the health risks associated with using public Wi-Fi are similar to the risks involved in using mobile networks. However, there are some specific risks associated with using public Wi-Fi networks and they are as follows;
Wi-Fi lowers mental processing speed
Researchers discovered that people exposed to 4G radiation had lower brain activity in various areas and had trouble concentrating. It doesn’t help that the next generation of fast internet, 5G technology, won’t be available for use for just a few more years. Because 5G Wi-Fi routers operate at higher frequencies than the more usual 2.4 GHz ones, users may be subject to more serious health hazards.
Wi-Fi sometimes causes insomnia.
Chronic sleeping issues like insomnia might develop as a result of ongoing Wi-Fi signal exposure.
Low-frequency modulation signals from gadgets like cell phones and Wi-Fi routers have been discovered to have an effect on sleep. Changes in brainwave patterns were seen in participants exposed to phone electromagnetic signals, as well as a significant increase in the difficulty of falling asleep.
According to specialists, chronic sleep deprivation can cause depression and hypertension to emerge.
Wi-Fi may be detrimental to childhood health.
According to a study, fetuses exposed to non-thermal radio frequency radiation, such as the EMFs from Wi-Fi, may develop their cells poorly, with delayed kidney development being a particular problem.
In young children, radiation can impede protein synthesis, which is necessary for tissue growth and development.
Heart issues can be caused by Wi-Fi.
69 participants were used in a study to examine heart rate variability provocation, and they were exposed to EMF radiation at a level equivalent to that emitted by 2.4 GHz Wi-Fi routers. It was discovered that several of them had actual bodily reactions to electromagnetic frequencies, such as an elevated heart rate that was comparable to someone under stress.
Wi-Fi can affect women’s memory.
In a study involving 15 males and 15 women, it was discovered that after 45 minutes of exposure to 2.4 GHz Wi-Fi from a wireless access point, the women performed poorly on a straightforward memory test. Women’s brain activity and energy levels changed noticeably when scientists assessed the patients’ brain activity.
Wi-Fi may alter fertility.
DNA fragmentation and reduced sperm motility have been linked to radio frequency exposure, which is akin to the EMFs from Wi-Fi, according to research. Exposure harms sperm, according to studies conducted on both humans and animals.
It was revealed in a different study that being exposed to specific wifi frequencies may inhibit egg implantation. Researchers showed that exposing mice to radiation for two hours each day for 45 days dramatically elevated the levels of oxidative stress. This may result in an abnormal pregnancy or a failed egg implant.
Free public Wi-Fi is evidence of how times have changed and internet access is now a requirement rather than a luxury. Being constantly linked has certain obvious advantages, but keep in mind that there are also some risks involved.
While Wi-Fi EMF exposure cannot entirely be avoided, there are things you may do to safeguard yourself, such as using blankets and protective cases. Additionally, a variety of tools are available to block electromagnetic radiation.
