A systematic review in Public Health Reviews examined occupational exposure to extremely low-frequency electromagnetic fields and cardiovascular outcomes. The authors searched six databases through August 19, 2026, included 14 studies with 49,709 participants, and found that half reported associations with cardiovascular outcomes, while the overall evidence was not strong enough to confirm causality. It is the second occupational review EMF Signal has covered in recent weeks, after a Nigerian narrative review of 50 Hz fields around high-voltage switchyards that looked at a wider set of health outcomes and concluded that ICNIRP and IEEE guidelines leave gaps on dose-response and long-term effects.

Quotes

"Seven of fourteen studies (50 percent) showed that there is an association between ELF field exposure and cardiovascular outcomes. However, the available evidence is insufficient to establish causality."

— Raeisi et al.

"Exposure to ELF fields may be associated with some cardiovascular outcomes. However, the confirmation of this relationship remains ambiguous, and it requires further investigations in future research."

— Raeisi et al.

"An association between occupational exposure to ELF electromagnetic fields and cardiovascular outcomes was reported in seven of the 14 studies included in this review."

— Raeisi et al.

"To assess the risk of bias in the included studies, the Joanna Briggs Institute checklist was used."

— Raeisi et al.
