Electrosensitivity (ES) is a descriptive term for symptoms caused by exposure to electromagnetic radiation (EMR). Other names for ES are: Electrohypersensitivity (EHS), Electromagnetic Sensitivity (EMS), Electromagnetic hypersensitivity and EMF syndrome.
Physical symptoms of ES can range from mild effects such as headache, nausea, tingling, skin reactions, anxiety, and tinnitus (buzzing/ringing in the ears) to painful and severe effects such as neurological conditions; cardiovascular, hormonal, and bloodsugar irregularities; seizures; paralysis; and stroke.

In Sweden, electrohypersensitivity (EHS) is an officially fully recognized functional impairment (i.e., it is not regarded as a disease). Survey studies show that somewhere between 230,000–290,000 Swedish men and women report a variety of symptoms when being in contact with electromagnetic field (EMF) sources.
