Caffeine Can Improve Our Physical And Cognitive Function Essay

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.

Caffeine is one of the most consumed psychoactive substances around the world. Caffeine is not bad for health, some researchers even show positive effects. Caffeine appears to reduce fatigue. And in this way also has an indirect effect on decision. Regarding cognitive function, caffeine has an effect on reaction time. Some studies also show a positive effect on long-term memory.

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

Even though I do not possess a caffeine produced disease, I have experienced the consequences of drinking high amounts of caffeine which includes anxiety, insomnia, gastritis, colitis, mild tremors, and irritability. Although small quantities of caffeine may not substantially cause serious problems, if consumed in high quantities (>400mg.), it might worse the conditions of an anxiety disorder, diarrhea, bipolar disorder, bleeding disorders, heart conditions, diabetes, glaucoma, osteoporosis, epilepsy, irritable bowel syndrome, and high blood pressure (webmd, 2009). In addition to the consequences of caffeine mentioned above, new studies have linked caffeine to psychotic symptoms (Grimson, 2011). At the moment, I do not suffer any of the diseases previously mentioned, but I do have a family history of diabetes, depression, and anxiety disorders. Thus, the predisposition to any of the risks of a high caffeine intake increases. In summary, the consequences of consuming high doses of caffeine vary from person to person, and it may elicit different effects, which may range from a mild change of mood to a complex psychotic break; therefore I considered quitting caffeine an optimum choice for a healthier

The primary literature article is titled, Dose–response study of caffeine effects on cerebral functional activity with a specific focus on dependence. This article consists of many parts including an abstract, introduction, materials and methods, and results. The articles aim is to explain the physiological functions of caffeine and how it affects the brain. The language used in this article is very specific and scientific. It consists of very precise word choice and both quantitative and qualitative information. In the introduction, this article mentions that the average daily caffeine consumption for all adult consumers and from all sources reaches 2.4–4.0 mg/kg for a 60–70 kg subject in the United States, UK and Canada (Nehlig and Boyet, 2000). This excerpt from the

All around the world, people drink coffee, tea and caffeinated drinks to wake up in the morning, to be more vigilant and alert throughout the day. Not only does this keep individuals alert but also allows them to focus and efficiently manage their time throughout their day. This quality of caffeine has caused it to be one of the most highly consumed psychoactive drugs. Individuals who require frequent intakes of Caffeine often feel tired, weak, drowsy if they tend to miss their cup of coffee early in the morning. Although, Caffeine is known for causing wakefulness and alertness it also has its downsides. If a person has a large dose of caffeine in a limited time, the drug could cause them trembling, anxiety and nausea. In long term effects,

Caffeine has become an integral part of most Americans lives, making it “America's most popular drug by far” (Brian). Most of the country will enjoy a cup of coffee in the morning or a few sodas during the day. Although most of the world’s population consumes caffeine in either coffee, tea, chocolate, energy drinks or sodas, the majority of those people are undereducated about the drug. There are many drawbacks to the drug, but also many benefits.

Depending on whether a person is a habitual or non-habitual caffeine drinker, caffeine consummation can have either a positive or negative effect on a person’s mood and performance (Childs & de Wit, 2006). One hundred and two (51 males and 51 females) nondependent caffeine users who consumed less than 300 mg of caffeinated beverages per week participated in a four experimental session study. Each participant was given four drug conditions in capsule form (placebo, 50, 150, or 450 mg of caffeine), each in random order, with three days intervals, between 9 a.m. and 1 p.m. Before and after each drug administration, the participant’s physiological data (heart rate, blood pressure) was measured. Also the participant’s had to take behavior tasks

Caffeine and its Long-term Physiological Changes To many people, caffeine seems like more of a necessity to start the day, or keep the day going, rather than a potentially harmful drug; however, most do not realize the long-term physiological changes that can occur as reported by several users. According to National Geographic, consumers spend 30 million dollars every year on caffeine tablets and roughly 50 billion dollars on caffeinated soda. Caffeine is a drug and as such makes changes the bodies. When people consume food or drink with caffeine in it the body responds by a raise the blood pressure, exciting the central nervous system, endorses urine formation, and speed up the action of the heart

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

One on the beneficial effects on caffeine, two the negative effects, and finally on trends in caffeine consumption

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

“Caffeine overdose can cause mania and anxiety, and can even lead to death” (Julian Cribb, 2014). Living in the present is full of hustle. Everyone has to race against the clock. Coffee has become a part of the breakfast menu, in order to eating breakfast fastest. The reason of drinking coffee every time for many people is fragrant smelling and mellow flavoring which make them feel perky and awake at work. They always understand that drinking coffee makes the brain more alert and awake (NUTRITION ARTICLES). But if you drink coffee too much, it would be harmful to your body. Many coffee drinkers are familiar with the symptoms "palpitation" that caused by coffee which is anxious that occurs when they drink coffee too much (NUTRITION ARTICLES). Coffee can raise blood pressure to those who suffer from high blood pressure already (Foster&Ted Kallmyer). Coffee may also cause anxiety and irritability, in some case with excessive drinking and some neurological symptoms. People who fond of drinking coffee and can't go without coffee should be aware of disadvantage of
