Caffeinated Drinks on Heart Rate.

Review of literature
      Has your heart rate ever increased after consuming a caffeinated drink? Did it decrease? Maybe it stayed the same? The researcher tested the effect of caffeinated drinks on a person’s heart rate.
      If you think you don’t do drugs, your wrong. Caffeine is an alkaloid found in coffee, tea, cacao, and some other plants. It is also present in most cola beverages. Caffeine was discovered in coffee in 1820. The drug increases the blood pressure, stimulates the central nervous system, promotes urine formation, and stimulates the action of the heart and lungs. (Leon L. Bram, 1876, p113)
      The researchers hypothesis is if caffeine is a stimulant, then it will increase a person’s heart rate, because the caffeine will absorb into the blood stream and reach the heart, causing the heart to beat faster. Caffeine acts as a stimulant by exerting a strong effect on the central nervous system. The effects of caffeine on the body may begin as early as 15 minutes and last up to six hours. Caffeine may increase heart rate, body temperature, blood flow to the skin & extremities, blood pressure, blood sugar levels, stomach acid secretion and production of urine (diuretic).

      Caffeine was originated in Ethiopia. It was found in coffee beans. Coffee shops sprang up throughout Europe - coffee was the fashionable drug of the 17th and 18th centuries; its delights, and the cravings for it, were the subject of J.S. Bach's "The Coffee Cantata". Eventually, the caffeine was found in tea, which was very popular throughout Europe. Over time, the drug is favored in mostly cola products.
