Hypertension is the medical term for high blood pressure. Approximately 90% of people with high blood pressure have “essential” or “idiopathic” hypertension, the cause of which is poorly understood. As used here, the terms “hypertension” and “high blood pressure” refer only to this most common form and not to high blood pressure either associated with pregnancy or clearly linked to known causes such as Cushing’s syndrome, pheochromocytoma, or kidney disease.
Despite reports suggesting short-term blood-pressure-raising effects resulting from caffeine ingestion, a few studies have claimed that long-term coffee drinkers have lower blood pressure than those who avoid coffee.7, 8 The consequences of long-term caffeine avoidance on blood pressure remain unclear. Significant amounts of caffeine are found in regular coffee, black and green tea, chocolate, some soft drinks, and some medications.
