Key result
Heart rhythm sensitivity to Earth's magnetic fluctuations varies widely, with no significant link to age.
Why the study?
The sensitivity of human heart rhythm to fluctuations of Earth's local magnetic field was analyzed to understand potential correlations with physiological frequencies.
Observational (n=17)
No
This study investigates the potential correlation between Earth's local magnetic field fluctuations and human heart-rate variability.
High inter-individual variability in geomagnetic heart-rhythm sensitivity, age-independent; hypothesis-generating for HRV effects but should not yet change practice.
The sensitivity of human hearth’s rhythm to the fluctuations of Earth’s local magnetic field is analyzed in this paper. Data collected during the long-term project of heart-rate variability (HRV) data from 17 female volunteers were used to correlate to measured fluctuations of Earth magnetic signals. Magnetic signals are collected utilizing the first global network of GPS time stamped detectors designed to continuously measure magnetic signals that occur in the same range as human physiological frequencies such as the brain and cardiovascular systems.

Alabdulgade et al. (2015) conducted an observational in Healthy volunteers (n=17). Earth local magnetic field fluctuations was evaluated on Sensitivity of heart inter-beat-intervals to local magnetic field fluctuations. Individual heart rhythm sensitivity to Earth's local magnetic field fluctuations varies widely, and age was not a significant factor in this sensitivity (r=0.107).
