Electromagnetic Hypersensitivity (EHS), also known as Electromagnetic Sensitivity (EMS) or Microwave Syndrome, is a controversial and poorly understood phenomenon where individuals claim to experience a range of symptoms they attribute to exposure to electromagnetic fields (EMFs) from various electronic devices and technologies. These symptoms are said to occur at levels of EMF exposure that are well below established safety limits.
Common symptoms reported by those who claim to suffer from EHS include headaches, fatigue, dizziness, sleep disturbances, skin rashes, and various neurological symptoms. These symptoms are said to occur when individuals are exposed to sources of EMFs such as Wi-Fi routers, cell phones, power lines, and other electronic devices. However, scientific research has not been able to consistently establish a direct causal link between EMF exposure and the reported symptoms.
The World Health Organization (WHO) classifies EHS as a "self-reported" condition, meaning that individuals who claim to have EHS describe their symptoms without corresponding scientific evidence to support a causal relationship between EMF exposure and their symptoms. Numerous double-blind studies have been conducted to investigate EHS claims, but the results have been inconclusive and often contradictory. Many of these studies have found that individuals who report EHS symptoms are unable to consistently identify when they are being exposed to EMFs, which suggests that the symptoms might not be directly caused by EMF exposure.
Scientific consensus suggests that the symptoms reported by individuals with EHS might be attributed to other factors, such as psychological or nocebo effects, where the belief in harm from EMFs could lead to a heightened perception of symptoms. It's important to note that the vast majority of research conducted by reputable scientific organizations has not been able to establish a clear and consistent link between EMF exposure at typical levels encountered in daily life and the reported symptoms of EHS.
As of my last knowledge update in September 2021, EHS remains a subject of debate and ongoing research. If there have been significant developments or changes since then, I may not be aware of them.
