While research on electromagnetic fields (EMFs) is ongoing, many environmentally sensitive individuals report adverse effects from high EMF exposure. Homes close to cell towers, power substations, or with high concentrations of smart meters may contribute to increased exposure.

Use online tools to map nearby EMF sources and visually inspect for transformers, transmission lines, or smart meters placed on or near bedrooms. Where possible, look for homes with analog utility meters or smart meters installed on detached garages. Bedrooms should be located away from exterior walls that house these devices, reducing overnight exposure.
