Electromagnetic Field Interactions with Biological Systems
Summary
Interactions between electromagnetic fields and biological tissues span a wide frequency spectrum, from extremely low‐frequency fields generated by power lines to millimetre‐wave radiation used in modern communications. At the molecular level, fields can influence charged biomolecules and ion channels, altering signalling cascades and gene expression. Cellular responses include modulation of calcium‐dependent pathways, reactive oxygen species production and changes in membrane potential. Systemically, these effects may manifest as altered neural activity, impacts on cardiovascular function or modifications of immune responses. Non‐thermal mechanisms—those not attributable to tissue heating—have gained prominence, revealing subtle but reproducible bioeffects. Concurrently, harnessing field exposures has led to clinical innovations, such as bone growth stimulation and targeted neuromodulation therapies. Environmental and occupational safety standards have evolved in parallel to protect public health. Ongoing research seeks to delineate thresholds for beneficial versus adverse outcomes, offering global insights into both the risks and therapeutic potentials of electromagnetic exposures.

Electromagnetic Field Interactions with Biological Systems publication trend
The graph below shows the total number of articles in electromagnetic field interactions with biological systems across all publications each year (not limited to Nature Index journals).
Technical terms
Electromagnetic field (EMF): A dynamic field of electric and magnetic forces generated by charged particles, described by frequency and amplitude and capable of interacting with biological tissues.
Radiofrequency radiation (RFR): A range of electromagnetic waves from 3 kHz to 300 GHz widely used in telecommunications and medical diagnostics.
Non-thermal effects: Biological responses elicited by electromagnetic exposures at levels insufficient to cause measurable heating, often mediated by ion channel modulation or signal transduction pathways.
Reactive oxygen species (ROS): Highly reactive oxygen-containing molecules that can alter cellular redox balance, contributing to signalling or oxidative damage depending on concentration and context.
