National EHS Awareness Day is observed worldwide every June 10 to highlight electromagnetic hypersensitivity (EHS), a condition characterized by increased sensitivity to electromagnetic fields from sources like cell phones and Wi-Fi. Established in 2020 by DefenderShield, a company specializing in EMF and 5G shielding solutions, the day encourages individuals with EHS to share their experiences. While EHS is not an officially recognized medical diagnosis and lacks scientific validation, many report symptoms such as headaches, fatigue, and sleep disturbances. On this day, participants are encouraged to engage in activities like digital detoxes and to spread awareness through social media using the hashtag #NationalEHSAwarenessDay. Cognitive behavioral therapy is often suggested as a management strategy for those affected by EHS.
