I want to share with you this article based on information provided by EFEIA, which explains in detail what electrohypersensitivity (EHS) is.

This health problem, increasingly common worldwide, remains difficult for most healthcare workers to understand. It is essential to shed light on this condition in order to improve understanding and support for people with the condition.

Electrohypersensitivity: a look at electromagnetic field sensitivity

Electrohypersensitivity (EHS), also known as electromagnetic hypersensitivity, is an increasingly recognised condition affecting people who experience sensitivity or allergy to electromagnetic fields (EMF). This sensitivity manifests itself through a variety of symptoms, from mild to extremely severe, which can worsen pre-existing health conditions.


What is electrohypersensitivity?

Electrohypersensitivity is a condition in which individuals exhibit adverse reactions to electromagnetic fields, even at levels well below the maximum permitted by international radiation safety standards. EHS sufferers report a range of health problems that they attribute to EMF exposure. These symptoms can be so debilitating that some people are forced to radically change their lifestyle, avoiding EMFs as much as possible and even stopping work.

Common symptoms

Symptoms of EHS vary considerably between individuals, but the most common include:

  • Dermatological: Redness, tingling and burning sensation of the skin.
  • Neurological: Headaches, dizziness, nausea, difficulty concentrating, memory loss, irritability, depression, anxiety, insomnia, fatigue, tremors and muscle spasms.
  • Cardiac: palpitations, arrhythmias, chest pain or pressure and fluctuating blood pressure.
  • Hearing: squeaking, buzzing or hearing loss.
  • Respiratory: Sinusitis, bronchitis, pneumonia and asthma.
  • Ophthalmological: Pain or burning in the eyes, deterioration of vision and cataracts.
  • Other: Digestive problems, abdominal pain, sexual dysfunction, dry mouth and eyes, and nosebleeds.


Recognition and protection

In some countries, EHS has been recognised as a functional impairment. A notable example is Sweden, where this condition is considered a functional disability, giving those affected maximum legal protection and financial support. This protection includes free accessibility measures, government subsidies and the possibility of forming disability organisations.

Initiatives and studies

The World Health Organisation (WHO) has taken steps to understand and address EHS. In October 2004, it organised a seminar in Prague together with the National Reference Laboratory for Non-Ionising Radiation and the Ministry of Health of the Czech Republic. This event brought together experts to review the current state of knowledge on EHS and provide useful information for those affected.

In addition, EFEIA is actively working on data collection through a Global EHS Census. This effort aims to shed light on the prevalence and effects of EHS, as well as to find practical solutions for those affected.

The role of Dr. Olle Johansson

One of the leading advocates for the recognition of EHS is Dr. Olle Johansson, a world leading authority in the field of EMF radiation and its health effects. Dr Johansson coined the term “screen dermatitis” and has been instrumental in the recognition of EHS as a functional disorder. Their work has been crucial in getting electrohypersensitive people the recognition and protection they need.


Electrohypersensitivity is a real and debilitating condition for many people around the world. Although more research is still needed to fully understand its mechanisms and effects, recognition and protection of those affected are crucial steps towards a more inclusive and equitable society. It is essential that health institutions, governments and communities work together to provide the necessary support and improve the quality of life of those suffering from this condition.
