on your blood pressure.
Coffee consumption has been hypothesized to be associated with blood pressure. Being caffeine is a stimulant there is good reason to suspect that coffee and high blood pressure might be related. Caffeine is a very mild stimulant and has a short life span in human body. It is also a self-limiting stimulant, because it acts on the kidneys to increase the rate of its own excretion. The relation between coffee consumption and incidence of hypertension is related to smoking status. Consumption of 3-4 cups of coffee per day decreased the risk of hypertension in non smoking men and women only. According to a study of the"American Journal of Clinical Nutrition', drinking coffee substantially raises your blood pressure for up to three hours after consumption. Researchers state that 200 to 300 milligrams of caffeine, equal to 2-3 cups of coffee depending on the strength, raised the systolic number by 8.1 millimeters of mercury and the diastolic by 5.7. This change took place within an hour of consumption. While researchers observed an immediate increase in blood pressure, they say that being a coffee drinker does not necessarily raise your blood pressure in the long term.
Now a day's hypertension is a most common and major health problem. High blood pressure is an obvious risk factor for stroke, kidney disease, coronary artery disease, all cause fatal and decreases life expectancy.
