Electromagnetic Hypersensitivity Syndrome (EHS) is a condition in which people are very sensitive to electromagnetic fields. In an area such as a wireless access point, they experience pain or other symptoms.
People with EHS have a variety of symptoms, including headache, fatigue, nausea, burning and itchy skin, and muscle pain. These symptoms are subjective and vary from individual to individual, which makes the disease difficult to study and has left experts divided on the validity of these claims.
More than 30 studies have been conducted to determine the link between the condition and exposure to electromagnetic fields from sources such as radar antennas, mobile phone signals, and Wi-Fi hotspots.
