High Blood Pressure

Caffeine doesn't usually appear to make most people at risk for heart disease or stroke. However, because of its stimulating effects on the nervous system, it has been shown in numerous studies to increase blood pressure.

Because high blood pressure may gradually damage arteries and restrict the flow of blood to your heart and brain, it raises your chance of having a heart attack or stroke. Fortunately, caffeine's effect on blood pressure seems to be temporary. Additionally, those who aren't used to consuming it appears to be the ones who are most affected. High caffeine intake has also been demonstrated to cause a rise in blood pressure during exercise in those who have both healthy and mildly elevated blood pressure. So it's important to pay attention to caffeine amount and timing, especially if you already have high blood pressure.
