These invisible energy fields surround us constantly, emitted by cell phones, WiFi routers, power lines, and household appliances. Scientific research has documented biological effects at exposure levels far below current safety standards, including impacts on DNA, cellular function, and various body systems. This content is for informational purposes only and is not a substitute for professional medical advice. (For a comprehensive overview, see our guide to EM hypersensitivity.) Key Takeaways EMF stands for electromagnetic field (EMF), an invisible area of energy produced by electrically charged objects including phones, routers, appliances, and power lines Two main types affect daily life: radiofrequencyRadiofrequency (RF) refers to electromagnetic waves in the frequency range of approximately 3 kHz to 300 GHz. This portion of the electromagnetic spectrum is used for wireless communication. RF energy... (RF) radiation from wireless devices and extremely low frequencyExtremely low frequency (ELF) refers to electromagnetic fields with frequencies between 3 Hz and 300 Hz. This range includes the 50/60 Hz fields produced by electrical power systems. ELF fields... (ELF) fields from electrical wiring and appliances Research documents biological effects at non-thermal exposure levels, meaning effects occur without any detectable heating of tissue Over 3,500 peer-reviewed studies in the BioInitiative Report (BioInitiative Working Group) link EMF exposure to effects on DNA, hormones, the nervous system, and reproductive health Current safety standards only address thermal effects, leaving a gap between what regulations permit and what research shows can affect biology What is EMF Radiation? EMFs (electromagnetic fields) are invisible areas of energy associated with electrical power and various forms of natural and artificial lighting. EMF radiation exists on a spectrum, ranging from ELF (extremely low frequency) fields produced by electrical wiring to RF (radiofrequency) radiation from wireless devices to visible light and beyond.You may also be interested in...What is Blue Light?
