There is a lot of ongoing debate as to whether or not WiFi can give you headaches. As more and more people rely on devices like mobile phones, more and more companies are responding with bigger and better WiFi (to keep the explanation simple).
In doing so, the world has graduated to 5G, a standard of radio waves meant to deliver better (faster) wireless connections to users. This newer 5G, which is a step up from the 4G, has raised health risk concerns. The debates arise due to the limited knowledge on 5G and its affects on humans.
First, what is the difference between 5G and 4G? The biggest difference is its radio frequency delivery system. With 4G, the system relies on large antennas to deliver those frequencies to your phone, however, 5G relies on small cell towers that can easily be placed on poles.
Your local telephone and light standards can quickly accommodate the installation of these small cell towers. For speed, the cell towers are placed 100 to 200 meters apart to generate faster radio waves.
In 2019, more than 240 scientists and doctors from 42 countries signed a letter requesting the United Nations further their research before allowing the technology to power people’s smartphones. Their expressed concern was the radio waves and health risks from 5Gs.
A 2018 study by the National Toxicology Program on 2G and 3G cellphones found radiation at those levels were able to cause cancer in animals. The agency said those cell phones should be regarded as a potential carcinogen for humans.
They also concluded that the radio frequency radiation (RFR) used by cell phones was found to be the cause for tumors in rats. Their study found that high exposure to RFR (900 MHz) used by cell phones was associated with tumors in the hearts, brains and adrenal glands of male rats.
Other studies have found that high mobile phone usage may be related with a higher rate of headache attacks due to the low radiofrequency electromagnetic fields (RF-EMF). The study, which included 114 adult men and woman migraine sufferers in the Neurology Clinic of Golestan Hospital, were observed for a period of three months.
After three months of mobile phone and WiFi use, scientists concluded that “the number and severity of migraine headaches were correlated significantly with an increased use of mobile phones during day and Wi-Fi per week.” They also found that “the usage of fixed-line telephones had no significant relationship with the study variables.”
In their conclusion, they recommended that patients suffering migraine headaches limit their use of mobile phones and instead, opt for fixed land line phone use.
