High Blood Pressure and Caffeine - A Dangerous Combination

Caffeine and high blood pressure can be a deadly combination. Simply said, the two things don't mix. Here are four reasons why caffeine is not good for those with hypertension:

1. Caffeine is a stimulant - Albeit a mild stimulant, caffeine can contribute to the rise of blood pressure. If your blood pressure level is already high, then this can pose some problems for you. Studies have not really shed light on why caffeine is linked to high blood pressure. Some studies show that those who have a regular intake of caffeine develop a tolerance to it while other studies show that those who regularly take caffeine have higher blood pressure. However, most of these studies agree that cream, sugar and other food have a tendency to dilute caffeine's effect on the body.

2. It can sharply raise blood pressure levels - These are studies confirming that caffeine intake can result in an immediate increase in blood pressure. The long term effect of taking caffeine especially in increasing the blood pressure level is still unknown. One common finding is the sharp blood pressure increase, albeit temporary, among those who take in caffeine on an irregular basis. Doctors explained that caffeine intake blocks the artery widening effect of the hormone adenosine - and constricted blood vessels lead to higher pressure. An alternative theory is that the blood pressure increase comes as a result of the release of adrenaline and cortisol which caffeine causes.

3. It makes one more susceptible to Artherosclerosis - The American Society of Hypertension conducted a study in 2002 that discovered the relationship between caffeine and the hardening of the arteries. The study confirmed that those with high blood pressure and who have a regular intake of caffeine are more prone to Artherosclerosis. What is to be noted is that the study also stated that it is too early to make firm conclusions about this subject.

4. It can cause heart problems - The danger of high blood pressure is related to the fact that it is associated with chronic heart problems. Caffeine compounds this because drinking more than four cups of coffee can increase the chance of developing heart problems.

Around 80% of people the world over still take caffeine daily, despite its reputation as a high blood pressure inducer. Caffeine can be taken in different forms, particularly in common beverages. Soft drinks, chocolate drinks, coffee and tea are some examples. Here are some foods with caffeine.

* 8-ounce brewed coffee -135 mg, * plain black tea-up to 70 mg, * 12-ounce Pepsi - 37.5 mg, * a bottle of Red Bull - 80 mg, * 1.45 ounce chocolate bar - 27 mg, * Midol (for menstruation pains) 60 mg, * pain relievers - 60mg.

Even when you do not have high blood pressure, doctors recommend up to only two 12-ounce cups of coffee. Also, avoid other drinks that contain caffeine. Soft drinks or tea can raise your intake of caffeine a day.

As much as possible, try to minimize, if not totally avoid, any caffeine intake, particularly if you already have high blood pressure. This way, you help avoid any further increases in your blood pressure.
