Michael Bevington, Chair of Trustees at Electrosensitivity UK, examines the history of Electromagnetic Hypersensitivity (EHS) over the past 275 years, highlighting key 18th-century discoveries and early reports of health issues related to electromagnetic fields (EMFs)

There have been various definitions of Electromagnetic Hypersensitivity (EHS) over the last 275 years. This article shows that EHS conscious symptoms in the 1700s were the same as from 5G in 2023-2024. It describes the wide spectrum of sensitivity to Electromagnetic Fields (EMFs). Finally, it lists subconscious symptoms and names for EHS.

The discovery of electrical sensitivity in 1733

Electrical knowledge developed in the early 1700s with Hawksbee’s electrostatic generator of 1719 and the Leyden Jar of 1745. Static electricity, when discharged, creates an electric current, which can cause serious ill health. On 8 April 1730, Stephen Gray, the ‘father’ of electricity, first showed that the human body conducts electric charges, which can be induced and transmitted wirelessly, using a boy as his conductor, suspended on insulating silk strings. Similarly, people whose electric field, charged by Wi-Fi and mobile phone signals, extends some distance from their bodies can cause significant ill health in people sensitised to EMFs.

Adverse EMF health effects were first recorded in 1733 by Du Fay in Paris. Professor Musschenbroek at Leiden felt as though he was struck by lightning, by then known as electrical. Winkler, in 1744, reported unsupportable pains. In 1745, Bose reported that wireless electric charges could alter cardiovascular rhythms and increase blood effusion from a wound, while in 1746, Trembly reported that electrification increased his pulse. Many researchers were Fellows of the Royal Society of London. Most short-term conscious symptoms specific to EHS before 1800 were identical to those of 2023-2024 near 5G transmitters (Table 1).
