Scientists warn that geomagnetic storms intense disturbances from solar explosions like coronal mass ejections can subtly increase both systolic and diastolic blood pressure, adding hidden strain on the cardiovascular system. Multiple studies have documented statistically significant correlations between geomagnetic activity and blood pressure fluctuations, especially during high solar activity periods.

These storms can trigger physiological changes via:

• Autonomic nervous system disruption, affecting heart rate and vascular tone

• Endothelial and inflammatory shifts, altering blood flow dynamics

• Circadian rhythm disruption, which may worsen blood pressure regulation

Research involving hypertensive volunteers during geomagnetic events showed elevated systolic readings, particularly at night and in men, suggesting a sensitive period of increased reactivity. While the effects are typically modest in healthy individuals, they can pose added risk to those with hypertension or cardiovascular vulnerabilities. Geomagnetic storms may also trigger a delayed physiological response, with blood pressure changes appearing hours to days after the storm underscoring the need for prolonged awareness.

While India Today’s article brings this intriguing connection to light, the conclusions align well with scientific studies highlighting that solar weather isn't just a cosmic spectacle but potentially a factor in our daily well-being.
