As an avid coffee drinker I know that caffeine is a heart stimulant, but how does it boost your heart rate and does it directly go to the heart? Caffeine proves to be one of the most popular stimulants in the world as people drink it in their tea and coffee. Caffeine has a direct effect on "cardiac cells". It affects your blood pressure and heart rate. It "raises blood pressure, or stroke volume of the heart by 4 points per minute, and heart rate goes up by about 3 beats per minute".

So now that we now there is a relationship between your heart and caffeine consumption the question lies in whether its bad for you or not... Excessive amounts of caffeine can be detrimental to the body. It allows for higher stress levels and rising blood pressure. The article Is Caffeine Bad for You? provided information from a study on caffeine consumption. When they measured the participants blood pressure after consuming the caffeine pills it was considerably high; "average of 4 millimeters (mm) higher for systolic pressure and 3 mm for diastolic". Stress levels were also recorded and the researchers found that they rose as well. The study reported that these "hormone levels also rose by an average of 32% on the caffeine days".


Finding all of this information out was a bit sad for me to hear. I am unfortunately one of those people who are addicted to coffee, but after learning all of this I realized that maybe three cups a day is a bit excessive. I knew I needed alternatives though so for those of you who are like me and need a pick me up every once in a while feel free to try these substitutes for your coffee.

I have written most of my blogs about this same subject, coffee. I feel like I am always drinking it as well, but of course I don't actually need it. When I was writing my posts I found this article It was really interesting to me. It specified how much coffee you should actually drink and the risks that come along with drinking too much.
