How does caffeine affect blood pressure?

Caffeine can cause a temporary increase in blood pressure due to its stimulant effects on the cardiovascular system. When consumed, caffeine can stimulate the release of catecholamines, which can lead to the constriction of blood vessels and an increase in heart rate. This surge in catecholamines can result in a temporary rise in blood pressure, particularly in individuals who are sensitive to caffeine or consume it in high quantities.

It's important to note that this increase is usually temporary and may not lead to chronic hypertension in healthy individuals. The body often develops tolerance to caffeine over time, which may diminish its impact on blood pressure.
