When Alcohol is present in the blood stream it covers the blood vessels and artery walls thereby increasing their tension and thereby increasing the blood pressure. Not only alcohol, but also Caffeine, Smoking, and Drugs also cause high blood pressure. An estimated 10% of hypertension cases are caused by alcohol abuse, three alcoholic drinks a day or more, with heavier drinkers having higher pressure. Caffeine causes a temporary increase in blood pressure, which has been thought to be harmless in people with normal blood pressure. Studies are suggesting, however, that regular, heavy coffee drinking (an average of 5 cups per day) can boost blood pressure, and in one study, this was sufficient to increase the risk for heart disease in healthy men. The potential risk of caffeine, however, pale next to the dangers of smoking. One study reported that smokers have blood pressures up to 10 points higher than nonsmokers. Cocaine is known to cause acute episodes of hypertension.

I found I had high-normal blood pressure last year and have tried to cut down on alcohol consumption, as well as salt in my diet. I actually do eat a pretty healthy, mainly vegetarian diet with a lot of Omega3 rich fish. But it doesn t seem to have had any affect on my blood pressure at all. Obviously, being high-normal I don t need to worry too much, but I d like to lower it a little. One constant seems to be Red Bull, which I drink almost every day. Is this to blame? The reason why I say Red Bull and not strictly caffeine is because of the concoction of other chemicals and taurine it also contains. RB has the same amount of caffeine as a mug of coffee or two mugs of tea.
