Myth 1: Coffee Causes Long-Term High Blood Pressure
Caffeine can cause a temporary spike in blood pressure but this effect is usually short lived. Regular coffee drinkers often develop a tolerance to this temporary increase. Research shows that moderate coffee consumption doesn’t increase the risk of developing chronic hypertension.
Myth 2: Decaf Coffee Has No Impact on Blood Pressure
Decaf coffee has very little caffeine, about 2–5 mg per 8-ounce cup. This is unlikely to affect blood pressure so decaf is a good option for those monitoring their hypertension.
Myth 3: All Types of Coffee Raise Blood Pressure Equally
Caffeine content in coffee varies by type and preparation method. For example an 8-ounce cup of brewed coffee has about 95 mg of caffeine, a 1-ounce shot of espresso has about 63 mg. Specialty coffees like cold brew or nitro coffee can have higher caffeine concentrations and more pronounced blood pressure responses.
Myth 4: Coffee Alternatives Are Always Better for Blood Pressure
Not all coffee alternatives are better for blood pressure. Some like yerba mate have caffeine and can affect blood pressure. Others like chicory or dandelion root coffee are caffeine free and won’t affect blood pressure. You need to consider the specific alternative and its ingredients.
Myth 5: Coffee Is Dehydrating and Raises Blood Pressure
Caffeine has a mild diuretic effect but regular coffee consumption doesn’t lead to dehydration. The fluid in coffee contributes to daily hydration needs and moderate intake doesn’t affect blood pressure.
Myth 6: People with High Blood Pressure Should Avoid Coffee Entirely
Moderation is key. For those with hypertension 1–3 cups of coffee a day is generally considered safe and may even have cardiovascular benefits. But always-monitor your individual response and consult with a healthcare provider.
Myth 7: Caffeine’s Effect on Blood Pressure Is the Same for Everyone
Everyone is different because of genetics, tolerance and overall health. Some people will experience more blood pressure changes than others. Know your own sensitivity to caffeine before considering the effects on blood pressure.
