EMF & health: what the evidence says
What’s established. The radiofrequency EMF from phones, Wi-Fi and 5G is non-ionizing: unlike X-rays, it lacks the energy to break DNA. Its one well-documented biological effect is mild tissue heating at high intensity — which international exposure limits (ICNIRP) are designed to prevent, and everyday devices stay far below.
What’s still debated. In 2011 the WHO’s IARC classified RF-EMF as “possibly carcinogenic” (Group 2B) — a category meaning a risk cannot be ruled out, not that one is proven. Large meta-analyses find no consistent link between mobile-phone use and brain tumours overall, though a few hint at a possible signal for very heavy, decade-plus use.[1][2][3] The science is genuinely unsettled — neither alarmist nor an all-clear.
Electrosensitivity & protection products. Symptoms some people attribute to EMF are real and distressing — but across dozens of blinded provocation studies and a 2024 WHO-commissioned review, people cannot tell when fields are on, and symptoms track perceived rather than actual exposure (a nocebo pattern).[4][5] The evidence-based steps are simple: increase distance and reduce unnecessary exposure. We can’t and don’t claim that “harmonizing” or “neutralizing” devices change clinical health outcomes — we share our experience, not medical proof.
Always do your own research and consult a qualified professional before making health decisions.
