EHS Day
June 10


About EHS Day
EHS Day is observed on 10 June each year, raising awareness of electromagnetic hypersensitivity (EHS), a condition in which individuals experience physical symptoms they attribute to exposure to electromagnetic fields (EMFs) from devices such as mobile phones, Wi-Fi routers, and power lines. In 2026, EHS Day falls on a Wednesday.
What is EHS Day?
EHS Day is an annual awareness day dedicated to electromagnetic hypersensitivity, a poorly understood and frequently invisible condition. People who live with EHS report a range of debilitating symptoms when they are in proximity to common electronic devices and wireless signals. The day was founded by DefenderShield, a US company specialising in EMF-protective technology, with the aim of bringing wider public attention to a condition that many people live with in isolation, often without a formal diagnosis or recognition from the medical community. The day also sits within a broader awareness of unexplained and invisible health conditions, which is shared with observances like Invisible Day on 4 July.
When is EHS Day?
EHS Day is observed every year on 10 June. In 2026, this falls on a Wednesday.
Why EHS Day Matters
Between 3% and 10% of people in developed countries report symptoms they associate with electromagnetic field exposure, according to research cited by the World Health Organisation. In Scandinavian countries, prevalence estimates have reached as high as 13%. Despite the scale of reported cases, EHS is not currently recognised as a formal medical diagnosis by the WHO or most national health authorities, largely because controlled studies have not been able to establish a causal link between EMF exposure and the symptoms described. This gap between the lived experience of those affected and the lack of medical recognition leaves many sufferers without appropriate support, feeling dismissed, and unsure where to turn for help. EHS Day seeks to address that gap by starting conversations and encouraging further research. For those interested in other areas of complex health awareness, Action Anxiety Day, observed on the same date of 10 June, raises awareness of another frequently misunderstood health experience.
How to Get Involved in EHS Day
There are several meaningful ways to engage with EHS Day and support those affected by electromagnetic hypersensitivity:
- Learn about EHS – Start by reading credible information about electromagnetic hypersensitivity from sources such as the World Health Organisation and peer-reviewed research. Understanding both the lived experience of EHS sufferers and the current scientific picture is essential before forming an opinion.
- Listen to those who live with EHS – Many people with EHS have spent years being told their symptoms are imaginary or psychosomatic. Simply listening without dismissal can make a significant difference to those who feel unheard within the medical system.
- Reduce unnecessary EMF exposure in your home – Whether or not you experience EHS, reducing unnecessary electromagnetic exposure is a practical step many people choose to take. Turning off Wi-Fi at night, using wired connections where possible, and keeping devices away from sleeping areas are simple measures.
- Support calls for more research – EHS remains understudied relative to its prevalence. Supporting organisations and researchers who are working to understand the condition better is a constructive way to help move the science forward.
- Raise the subject at work – Many EHS sufferers struggle in office environments with dense Wi-Fi networks and multiple screens. Raising awareness with employers about the possibility of workplace accommodations could make a meaningful difference to affected colleagues.
- Share information on social media – Use #EHSDay and #EHSDay2026 to share information about electromagnetic hypersensitivity. Increased visibility helps reduce the stigma many sufferers face.
- Consider the broader issue of digital health – EHS Day is also an invitation to reflect on our growing dependence on wireless technology and the importance of understanding its effects on human health more thoroughly as usage increases globally.
History of EHS Day
EHS Day was founded in 2020 by DefenderShield, a US-based company that produces radiation-shielding products for electronic devices. The founders recognised that electromagnetic hypersensitivity, despite affecting a meaningful proportion of the population, remained almost entirely absent from mainstream health conversations. By establishing a dedicated annual awareness day on 10 June, they aimed to give a voice to those living with the condition and to push for greater scientific and medical engagement with the topic.
Electromagnetic hypersensitivity itself was first described as a distinct phenomenon in the 1980s, as the proliferation of computer workstations in offices began to coincide with a rise in reports of skin rashes and other symptoms among workers. In 2005, the World Health Organisation convened an international workshop on the subject in Prague, acknowledging electromagnetic hypersensitivity under the alternative label of Idiopathic Environmental Intolerance attributed to electromagnetic fields (IEI-EMF). While the WHO stopped short of classifying it as a medically diagnosable condition, the workshop recognised the genuine suffering of those affected and called for more research into potential biological mechanisms.
As the world’s dependence on wireless technology has grown, so has the number of people reporting EHS-related symptoms. The rise of 5G networks, smart home devices, and near-constant mobile phone use has kept the debate very much alive, making EHS Day increasingly relevant with each passing year.
Noteworthy Facts About EHS Day
- Between 3% and 10% of the population in developed countries report symptoms they associate with electromagnetic field exposure, with some Scandinavian studies suggesting figures as high as 13%.
- EHS was first widely reported in the 1980s, linked to the growing use of computer monitors in office environments.
- The World Health Organisation convened an international workshop on electromagnetic hypersensitivity in Prague in 2004, recognising it under the label IEI-EMF.
- Common reported symptoms include headaches, fatigue, difficulty concentrating, sleep disturbances, and skin sensations such as burning or prickling.
- Nearly 50 controlled scientific studies have attempted to reproduce EHS symptoms in laboratory conditions; none have established a clear causal link between EMF exposure and the reported symptoms.
- EHS Day was established in 2020 by DefenderShield, and is observed annually on 10 June.
Frequently Asked Questions
What is EHS Day?
EHS Day stands for Electromagnetic Hypersensitivity Day, an annual awareness observance on 10 June dedicated to raising awareness of EHS, a condition in which people report physical symptoms related to exposure to electromagnetic fields from wireless technology and electronic devices.
When is EHS Day in 2026?

Is electromagnetic hypersensitivity a recognised medical condition?
EHS is not currently classified as a formal medical diagnosis by the World Health Organisation or most national health authorities. However, the WHO has acknowledged the condition under the label IEI-EMF and recognises that the symptoms reported by sufferers are real and can significantly affect quality of life. The scientific debate around its causes continues.
