Fadlou Allah and colleagues at Nova Southeastern University (Cureus, 2026) synthesize 29 studies from 2000 to 2026 on how geomagnetic and man-made electromagnetic fields affect heart rate and heart rate variability in healthy adults. The included studies varied substantially in exposure type, intensity, duration and metrics, and reported effects were inconsistent, often limited to transient changes in selected HRV indices. Geomagnetic and local magnetic field studies more often reported HRV associations, but the review concludes the evidence does not confirm a consistent effect on heart rate or HRV in healthy adults.

"After two-stage screening and duplicate removal, 29 studies were included, which varied substantially in exposure type, field intensity, exposure duration, HRV metrics, sample size, and analytic approach."

— Fadlou Allah et al., Cureus

"Geomagnetic and local magnetic field studies more often reported associations with HRV, hemodynamic variation, or HR/HRV synchronization, but these findings were heterogeneous and of uncertain clinical significance."

— Fadlou Allah et al., Cureus

"Overall, evidence from the studies reviewed does not confirm a consistent effect of geomagnetic or man-made EMF exposure on either HR or HRV in otherwise healthy adults."
