Does Coffee Increase Blood Pressure? An Expert's Perspective

Caffeine is known to cause a brief but dramatic increase in blood pressure, even in those who don't have high blood pressure. The exact cause of this increase is still unknown, and the effect of caffeine on blood pressure varies from person to person. Studies have shown that coffee can increase blood pressure up to three hours after consumption, but regular coffee drinkers may not experience this effect. Caffeine is a vasoconstrictor, meaning it decreases the size of blood vessels and may increase blood pressure.

It interacts with different receptors in the brain to produce its effects. However, other compounds in coffee, such as antioxidants and phenols, may also play a role in its effects on blood pressure. For people with high blood pressure, current research suggests that daily coffee consumption is unlikely to have a significant impact on blood pressure or on the overall risk of heart disease. A two-year follow-up study of older people found that the amount of coffee a person drinks determines its effects on blood pressure.

Boiled, plunger pot, Turkish and espresso coffee can increase blood cholesterol levels, but filtered, spiced and instant coffee don't.The research on the relationship between coffee consumption and hypertension has been conflicting; some studies support a link between them, while others do not. An Italian study from 1987 even suggests that coffee may help lower blood pressure. Ultimately, it is important to note that everyone reacts differently to caffeine and coffee, so it is best to consult with your doctor before making any changes to your diet.
