Heliobiology: Resonance Between Solar Activity and Health

Key Takeaways Heliobiology studies whether rhythms of solar and geomagnetic activity leave measurable traces in human physiology. Its observational arc runs from Alexander Tchijevsky’s 1920s historiometry to the post-satellite era of space-weather correlation studies. The core mechanistic puzzle is amplitude. A strong geomagnetic storm perturbs only about one percent of the steady background field, orders…
