Best-Known Reasons Why Caffeine Could Cause Blood Pressure

By Ray Jennings

Most people consume greater amounts of caffeine in the form of tea, coffee, or our favorite chocolate bar, when that cut off point for the vital presentation is approaching, or while studying for an exam till the last minute. This is as it is regarded to be a stimulant, the intake of which is known to warn the mind and body, and drive away sleepiness. Caffeine is present in tea and coffee in lower amounts than chocolate, as well as in colas and 'energy' drinks. However , before you pop that bar of chocolate, take a look at the studies that have established a possible relation between caffeine and blood pressure.

Caffeine is known to briefly raise blood pressure. This is why it is referred to as a stimulant and why we become alert on consumption of caffeine. It has the consequences of blocking the hormone called adenosine that functions to dilate the arteries, a consequence of which is high blood pressure. Higher levels of adrenaline are also produced as a consequence of consumption of caffeine. This is also known to increase blood pressure.

Thus, it is assumed that caffeine causes high blood pressure. However , there is more to this presumption than what meets the eye. The consequences of caffeine on blood pressure are yet to be confirmed. There has been a long standing debate about whether caffeine and blood pressure are related, and whether its consumption is directly related to the rise in blood pressure.

Research studies have shown that folk who drink drinks that contain caffeine on a regular basis are at a lower likelihood of developing raised blood pressure, rather than people who don't drink it, or drink it rarely. Studies have even proved that lengthened consumption of caffeine makes a person long suffering to its exciting effects. Those who have standard blood pressure need not limit intake of their regular dose of coffee and tea. Actually, caffeine is known to have a couple of antioxidant properties that are helpful for the body.

On the other hand, people who have already got hypertension or are at a risk of coronary disease, should first talk to their doctor before deciding the amounts of caffeine they consume, and should beware of over the top intake, as it can lead to one or two health issues that can happen as a consequence of elevated blood pressure.

Further, research has demonstrated that varied products containing caffeine have different effects on the body in the longer term. While coffee and tea are known not to have drastic effects on blood pressure, and in a few cases, even decrease the risk of developing blood pressure issues, excessive consumption of colas and sodas containing caffeine are known to extend the chance of developing high blood pressure. To grasp more on the caffeine content in varied beverages read :

Because of the swift effect caffeine has on the human body, it is considered a drug. So, the proportion between caffeine and blood pressure must be monitored, as this drug can affect the effectiveness of the drug one may be consuming to observe blood pressure levels.

Much as it may have been asserted, that caffeine doesn't increase the risk of developing raised blood pressure, it's still sensible to continuously reduce the amount consumed for those that already suffer from it. The reason it should be done gradually is because utterly stopping the intake of caffeine suddenly can lead to a few caffeine withdrawal symptoms, for example headaches, fatigue, anxiety and nervousness. Therefore, it's a hard choice, deciding whether to reduce or increase the intake of caffeine, specially since the analysis regarding caffeine and blood pressure is still obscure, and not complete.
