Linkages Between Geomagnetic Activity and Blood Pressure

Area of Science:

• Geophysics
• Cardiovascular Physiology
• Environmental Health

Background:

• Geomagnetic activity, influenced by space weather, is a global phenomenon.
• Blood pressure (BP) regulation is complex and can be influenced by various environmental factors.
• Existing research suggests potential, but not fully understood, links between geomagnetic field (GMF) changes and human physiology.

Purpose of the Study:

• To critically review and synthesize evidence on the relationship between geomagnetic activity and blood pressure.
• To evaluate the consistency and magnitude of reported BP changes associated with GMF variations.
• To identify factors influencing individual responses to geomagnetic influences on BP.

Main Methods:

• Comprehensive literature search across four major scientific databases (PubMed, Web of Science, EMBASE, Biomedical Reference Collection).
• Systematic screening of titles and abstracts of peer-reviewed English-language publications.
• Critical analysis of evidence for and against GMF-BP linkages.

Main Results:

• A preponderance of evidence suggests that significant GMF changes can impact BP.
• Reported BP increases, primarily in systolic blood pressure (SBP), range from 3-8 mmHg.
• Increased sensitivity to GMF-linked BP changes is observed in women and individuals with hypertension.

Conclusions:

• Geomagnetic activity represents a potential environmental factor influencing blood pressure.
• The precise timing and mechanisms of GMF-induced BP changes require further investigation.
• Future research should focus on identifying responders and non-responders to GMF variations for clinical relevance.
