Informative Speech : The Negative Effects Of Caffeine

Caffeine’s mental appeal is just as trendy as its physical purpose. Caffeine has been proven to stimulate the central nervous system. Caffeine stimulates the Central Nervous System at high levels, like the medulla and cortex, and even has the ability to reach the spinal cord in larger doses. The effect of caffeine in the cortex is a clearer thought process and also can rid the body of fatigue. This gives people a greater ability of concentration for 1-3 hours. For athletes competing in sports where quick thinking and rapid reactions are necessary, caffeine can provide a huge edge. However, these results are much more inconsistent than the experiments done on caffeine in endurance sports. (http://www.garynull.com/Documents/CaffeineEffects.htm)

Caffeine has many negative effects on humans, such as increased heart rate (Lane, J.D., 2002), depression (Goldstein, 2008), and addiction to this “drug.” You may be asking yourself, “What is caffeine?” Well, caffeine is actually a stimulant (Barone, Roberts, 2008) that is found in beverages such as tea, coffee, and soft drinks. In fact, caffeine is the highest grossing and most used stimulant in the United States (Barone, Roberts, 2008). It is estimated that 85% of adults living in the United States consume caffeine on a daily basis (Barone, Roberts, 2008). That means for every 100 adults, 85 of them have had a drink that contained caffeine on any given day. One reason caffeine is so widely available compared to other stimulants is

“Participants either receive a placebo or a 200-miligram caffeine table five minutes after studying a series of images,” and by giving caffeine after the experiment, researchers eliminate “caffeine's effects on attention, vigilance, focus, or other factors.” After 24 hours, researchers test participants’ ability to recognize images and some of the images are new; some are the same as they studied yesterday; some are ones that look similar but are different. The results show that the caffeine group has more people that can differentiate similar images from the original images instead of recognizing them as the same. This conclusion is really significant to show that caffeine could enhance memory because “the brain's ability to recognize the difference between two similar but not identical items, called pattern separation, reflects a deeper level of memory retention.” (Michael Yassa, 2014). Therefore, we can conclude that caffeine itself, despite of its other effects on human, could really help people improve their memory. Moreover, since caffeine can also increase attention, focus and vigilance, it could also help people memorize more effectively. Overall, caffeine could both directly and indirectly help the memory become more
