Espresso And Caffeine And Hypertension
Saturday, May 19th, 2012“
There have been several clinical studies into the effects of coffee and caffeine on blood pressure, these studies have shown rather inconsistent results.
Drinking a regular amount of coffee, say 2 – 4 cups a day, may raise blood pressure slightly. Respected agencies including the Food and Drug Administration, the National Academy of Sciences and the U.S. Surgeon Generals office have stated that caffeine carries no health risks. Any such effects are not permanent, passing within a few hours. This is because, unlike alcohol or smoking, caffeine doesn’t accumulate in the body. Some people who drink coffee regularly can develop a tolerance to it, such that they no longer notice any effects even after several cups of coffee. If you have high blood pressure and drink a lot of coffee, the results of studies suggest that if you stop drinking coffee (or possibly switch to decaffeinated) you may experience a slight fall of your blood pressure, but dont expect a dramatic change.
Caffeine is a mild stimulant and there is therefore reason to expect that drinking larger amounts of coffee and other high caffeine drinks might lead to a rise in blood pressure.
But, caffeine is only a very mild stimulant, and as mention above, passes through the body quite quickly. Caffeine is also self-limiting, because it acts on the kidneys to raise the rate of its own excretion. For most people moderate drinking of coffee (4 – 5 cups per day) is considered perfectly safe. Pregnant women should stay below 300mg of caffeine per day. (Remember that caffeine can be found in other products like Tea, Cola, Sports Energy Drinks and Chocoalte.) Don’t Smoke and Drink Coffee Caffeine can be a mild central nervous system stimulant.
