Essay On Caffeine

This article discusses the affects caffeine has on several aspects of human health. These included toxicity, cardiovascular effects (arrhythmia, heart rate, cholesterol and BP), bone/calcium balance, behavior, and reproductive and developmental effects. It also discussing the affect caffeine intake has on children and reproductive-aged women.

Caffeine is a natural product that is extracted from the raw fruit of coffee plants over sixty creased alertness. Caffeine gives most people a temporary energy boost and elevates mood..species to be exact. kola nuts, cocoa, yerba maté, guarana berries, coffee beans and teas contain this. Caffeine is rapidly absorbed in about 30 to 60 minutes in our bodies after ingestion. Caffeine is defined as a drug because it stimulates the central nervous system, causing increased alertness. Caffeine gives most people a temporary energy boost and elevates mood.caffeine can also be in things like over the counter medications, and pain relievers.

An idea for future research concerning this study is the long-term effects of frequent caffeine use and if older adults occupation status impacts their memory level of performance. Conducting research on the long-term effects of caffeine is imperative because researchers are suggesting that it can help participants during the three to four hours after consumption but doesn’t discuss the impact of frequent (years) use of caffeine on the human body. These two ideas can lead to scientific understanding because it has the ability to serve as a rationale for memory performance. Generally, anytime a drug enters the body frequently the host becomes desensitized to the dosage. If an young adult started utilizing caffeine on a daily basis due to the struggle of meeting her occupation requirements how would that impact her memory when she becomes an older adult? If theses ideas are research it will serve as a solution to some of the limitations in the previous

The result showed that there was no difference between the number of correct congruent words between people who were given and told caffeine and the people who were given decaf and told caffeine. In case of incongruent word count there was a significance difference in the expectancy for the people who consumed decaf/caffeinated suggesting that the expectation of consumed caffeine can improve memory.

While in college, students are often faced with large amounts of work, an immense amount of study commitments and the general pressure to perform well academically. As many students who are currently or have completed college know, maintaining a high level of quality through all of this work can be a very energy-taxing endeavor. This has led many college-aged students to turn to caffeine, as a supplement to their lives (Malinauskas et al. 2007). Common reasons that have been found to drive caffeine usage has been to help deal with low amounts of sleep, or to improve on one’s energy and alertness (Institute of Medicine, 2001; Malinauskas et al. 2007; Kilpeläinen et al. 2010). In previous research, a number of studies have demonstrated people who have been given a caffeinated beverage have performed better on memory tasks compared to a people given non caffeinated drinks (Capek & Guenther, 2009; Paulus et al. 2015; Sherman et al. 2016), while a few other studies have found a causal link to improved cognitive ability after the use of

Thesis: Caffeine is something that almost everyone has consumed and some people are even addicted to. Caffeine has negative and positive effects on one’s health

Specifically, researchers Rogers et al. (2012) have demonstrated how caffeine consumption versus abstinence effect functioning levels. In order to do this, they gathered a sample of 369 participants and assessed them using mental performance and motor tasks, as well as mental alertness scales to measure the effects of caffeine. Results showed that there was a significant effect of caffeine in all areas other than recognition memory. The study also yielded results that show a reduction in sleepiness, while an increase in anxiety and jitteriness. In addition to caffeine, another drug called L-theanine, commonly found in teas, has also been shown to improve cognitive performance as well. In this particular experiment, there were 44 participants that were presented with a choice-reaction-time task, virtual-search task, egocentric mental-rotation task, and an attention-switching task after drinking a tea-based soft drink that combined caffeine and L-theanine. With the consumption of this beverage, results showed that the drink did improve task-switching accuracy, increased alertness, decreased fatigue, and increased

Caffeine consumption was associated with fewer cognitive failures. This effect was apparent when non-consumers were compared with consumers which suggest that caffeine withdrawal did not underlie these effects (Smith 2001).

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

B) What have other researchers already discovered about this topic? Other researchers have found that caffeine is one of the most psychoactive substances consumed (Gilbert, 1984). Several studies have showed significant findings in which caffeine can affect effects in mood including increasing rates of happiness, well being, calmness, and alertness (Zwyghuizen-Doorenbos, Roehrs, Lipschutz, Timms, & Roth, 1990). It has also been shown though research that caffeine can elicit anger, anxiety, and nervousness depending on the dose given to participants. Low doses are more likely to increase feelings of happiness, and positive thoughts, while higher doses can elicit anxiety and nervousness. Alcohol has also been researched with its affect on memory. Participants whom had consumed alcohol were more likely to recall more words in a memory test rather than when they were not intoxicated. Through this research it has been argued that drugs achieve their affects on memory by the effects of a participants mood (Bower, 1981).

Research has proven that caffeine affects you brain directly. Studies show that you can rely on caffeine in small doses to jump start your basal forebrain, the part of the brain that processes information (Fisone, Borgkivist, Useillo). It affects a “group of projection neurons located in the striatum, the main receiving area of the basal ganglia” (Fisone, Borgkivist, Useillo). This means that caffeine makes information move faster within the nervous system, which is in direct control of the brain. Researchers at the Radiological Society of North America ran a series of simple tests such as having volunteers answer questions by clicking “yes” and “no” buttons as fast as they could remember the information. The information that each volunteer needed to know was stored in their short-term memory since the information was given to them 12 hours prior to testing. Random volunteers were given caffeine, about the amount of two cups of coffee, and their results were compared to those volunteers that did not have caffeine. In the caffeine condition," the volunteers demonstrated a tendency towards improved short-term memory skills and reaction times during the task (“Coffee Jump-starts

And caffeine may not be a good choice for people who are highly sensitive to its effects or who take certain medications.” Site:www.eatingwell.com

is derived from a bean or from tea leaves and can be found in the

The first and most obvious benefit of caffeine is that is improves memory, reaction time, and basic mental functioning. Michael Yassa, an assistant professor at Johns Hopkins, did a study on caffeine and memory. He gave half of his patients 200 milligrams of caffeine and the other half a placebo and tested their ability to recall images. He proved that caffeine improves memory for up to 24 hours after it is consumed (Gatlin). There is not much information on the long-term memory effects of caffeine, but scientists are learning more everyday.
