In our modern society, electronic devices have become integral to our daily routines, offering convenience and efficiency. They enable us to engage in various activities, such as browsing the internet or utilizing microwaves to reheat food. However, as technological advancements progress, there has been an unprecedented proliferation in the number and diversity of sources emitting electromagnetic fields (EMF).
EMF radiation, a type of energy produced by electrical and electronic devices like smartphones, laptops, tablets, Wi-Fi routers, and power lines, poses minimal risk to humans when present in low levels. Nevertheless, certain individuals exhibit heightened sensitivity to its effects, a condition known as Electromagnetic Hypersensitivity (EHS).
EHS manifests as a collection of physical and psychological symptoms experienced by individuals upon exposure to EMF from devices such as cell phones, Wi-Fi routers, and other electronic devices. Common symptoms associated with EHS include headaches, fatigue, dizziness, nausea, skin rash, and a range of other physical and psychological manifestations.
Determining the prevalence of EHS poses challenges due to the wide variation in estimates. Some surveys conducted at medical centers suggest a low incidence, with only a few individuals per million in the population being affected. Conversely, surveys conducted by self-help groups indicate much higher numbers, with approximately 10% of reported cases being considered severe.
It is noteworthy that the prevalence of EHS and the reported symptoms may differ across regions. Research has revealed that EHS is more prevalent in Sweden, Germany, and Denmark compared to the United Kingdom, Austria, and France. Scandinavian countries, in particular, have shown a higher incidence of symptoms related to computer screens, often involving skin disorders. It is important to recognize that symptoms similar to those reported by individuals with EHS are relatively common among the general population.
Over time, there has been an upward trend in the number of individuals self-identifying as sufferers of electromagnetic hypersensitivity. This trend has been observed since the advent of the first wireless cellular network (1G), with the first documented case reported in Sweden in the late 1980s. Presently, it is estimated that approximately 3% to 5% of individuals in many countries claim to experience EHS symptoms, with a higher prevalence reported among women compared to men.
