The Effects Of Caffeine On Cognitive Stimulation

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’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)

Thesis: Caffeine can have many different effects on the body depending on the amount of consumption.

An independent samples t-test was conducted to examine the difference between experimental conditions on test performance. The results indicated a significant difference between participants who consumed the caffeinated beverage and participants who did not, with participants in the caffeinated group (M = 7.64, SD = 2.41) performing worse than participants in the non-caffeinated group (M = 9.81, SD = 3.16), t (97) = 2.14, p < .05.

In the fast paced life of a college student, it is not uncommon for tasks and due dates to quickly pile up, demanding more hours studying and less hours sleeping. Any amount of sleep deprivation can lead students to consume caffeinated beverages, particularly coffee, to help them stay awake and get their work done. According to the University of Michigan (2015), Caffeine acts in the body by effecting the central nervous system and may start to

Symptoms that follow caffeine consumption are: anxiety, panic attacks, increased heart palpitations, trembling, stress, heartburn, and the deprivation of sleep (Driedger, Doyle par 2). Over time these symptoms can become more severe and eventually will become a major disturbance in one’s life. The anxiety that comes from this can be especially harmful to those who suffer from anxiety disorders, such as GAD-General Anxiety Disorder and Panic Disorder as the caffeine can stimulate a panic attack (Human par 3). The most apparent concern of caffeine consumption, is its effects on teen life. Dr. Jim Lane, a researcher at Duke University stated, “Teens are chronically sleep deprived. Caffeine use might be a consequence of that, and also a cause. Drinking coffee could lead to sleep-onset insomnia, or a delay in going to bed, that contributes to sleep deprivation” (Teens par 7). This shows that as the caffeine trend among teens continue, the link to teen sleep deprivation strengthens. Not only does it prevent the continuation of sleep, but also the process of even falling asleep is delayed. The more deprived of sleep these

Many people start their day with a cup of coffee. According to John Hopkins, “Around 90 percent of Americans consume caffeine every single day in one form or another”. It seems if we need a wakeup call to our morning, many of us grab caffeine to give us that extra boost of energy. How much caffeine is ok for the average person each day? The Dietary Guidelines Advisory Committee from Healthgov.com recommend 3-5 eight ounce cups of coffee per day or up to 400 milligrams per day of caffeine for the average healthy consumer. Caffeine is a CNS stimulant drug known as trimethylamine. Caffeine is naturally found in chocolate, coffee, cocoa beans, kola nuts, and tea. It is also added to drinks such as soda and

The intent of caffeine and sleep deprivation is to help the students through pressure and stress of studying from courses that they are taking. However, in actuality, caffeine and sleep deprivation effectively enlarge the gap between proper sleep and restfulness needed for body to function efficiently. However, the effects of caffeine on elevated cognitive processes are well researched even though it is “useful for restoring basic alertness and vigilance” (Huck 489). Although, caffeine seems to provide an equal opportunity for students to excel in their studies regardless of the lack of sleep that they are receiving, there is evidence that suggests caffeine may have a distinct advantage over needed sleep. Furthermore, the paper will

Caffeine is a stimulant of the nervous system which affects many aspects of the body. The overall effect of caffeine consumption is an overall feeling of awareness and higher levels of energy. Caffeine is the most used drug in the world. From coffee, tea, soda, to daily energy boosters and energy drinks, caffeine has become mainstream in American society, so much so, that over 90% of Americans drink caffeine on an everyday basis (Villanova). This is due to caffeine’s addictive nature. This drug affects almost every aspect of the body in some way, but especially performance. Our experiment is specifically testing the effect of caffeine on athletic performance and intellectual capacity. To test such things on human subjects, it would be very

According to Smith (2001), he found that cognitive performance over the course of a working day was improved more in people who consumed above average amounts of caffeine than those who consumed less than average (Smith 2001).

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).

Ever stay up late studying for a test or exam and wake up exhausted? Or just experienced a long day and need an extra boost? Many people believe caffeine is the answer to anyone’s drained state of being. Healthline.com explains that, “Caffeine reaches your brain quickly and acts as a central nervous system stimulant.” Caffeine is commonly referred to the most widely used drug on the planet, so the next question is which caffeine-filled product is the most efficient? It is widely debated whether energy drinks or coffee can provide the best balance of caffeine, flavor, and other ingredients, but after researching, I have come to conclude coffee is superlative in all aspects.

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).

Coffee is perhaps the most widely used stimulants in the world. In fact more than half of American Adults (61 percent) consume coffee on a daily basis (National Coffee Association, 2014). Drinking coffee makes one feel more attentive and alert because it is a highly lipid soluble, so it tends to cross from the bloodstream into the brain very fast and that one can feel the effects pretty quick. This is shown by the research in animals that coffee has shown that it reaches peak accumulations just within minutes of ingestion (Ryan L). And it hangs around in the brain, stimulating the regions that control sleep, mood, and concentration, slowly dissipating over three to four hours, which is plenty of time for you to get through your morning inbox, survive the staff meeting, return a few calls, and then get
