Fig. 4From: Correlations between geomagnetic field and global occurrence of cardiovascular diseases: evidence from 204 territories in different latitudeThe mechanistic basis of Internal Geomagnetic field and External Geomagnetic disturbance (GMD). *Geomagnetic field protects Earth from ionizing radiation coming from Solar Wind which causes disturbance of electric and magnetic field. Short-term geomagnetic disturbance modulates autonomic nervous system (ANS) and subsequently decreases heart rate variability (HRV). GMD overstimulates photo/magnetic-reception system in intrinsically photosensitive retinal ganglion cells (ipRGCs) and impacts circadian rhythm and melatonin secretion in pineal gland. GMD can alter the toxicity of air pollution which indirectly enhance the association between air pollutants and CVDs eventsBack to article page
