Caffeine's Negative Effects On The Human Body

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.

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

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

Caffeine is a psychoactive drug and potentially deadly in large amounts, especially for adolescents (Hershorin, Lipschulz, Schaechter & Seifert, 2011). Caffeine is one the most common energy drink ingredients and one of the most widely consumed substances in the world. According to the National Institutes of Health (NIH), caffeine is a chemical stimulant compound found in various plants that acts as a central nervous system stimulant. Caffeine is produced naturally and artificially. Caffeine is found mainly in coffee, tea, soda, chocolate, energy drinks and some over-the-counter medications. Due to the increasing demands placed on teenagers today, caffeine is becoming more prevalent in adolescents. While the American Academy of Pediatrics recommends children have no more than 100 mg of caffeine a day due to unknown medical conditions, the fact a teenager’s brain is still in a developmental stage, and the importance sleep plays in the developing brain. Table 1, shows the amount of caffeine for the energy drinks in this report. (Note-this does not include the caffeine from blend ingredients)

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

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

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

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

For centuries, products containing caffeine have been used in order to stay awake, enhance physical performance, or simply just for the taste of it. However, how does caffeine really affect your body and the activities that you perform, both physically and mentally? Caffeine is the most used drug in the world being that it is found in coffee, tea, chocolate, soda beverages, and much more. Some research shows that caffeine has aided the body by enhancing the physical endurance activities by at least 12% (Jenkins 1). This caused many athletes to begin using caffeinated products in physical sports competition in order to enhance their abilities. This forced major sports facilities to ban the use of caffeinated products before athletes perform.

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 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

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

Just like how modern technology has been embedded into lives of students, caffeine has become a necessity in student’s daily life as well. The workload of a college student can be overwhelming and it drives students to rely on caffeine. When they rely on caffeine for their body to function, they overlook an important aspect of their health conditions which is the absence of sleep. Students can be at risk for consuming too much caffeine especially when now a days, students lose track of their daily intake. Although there are beneficial aspect of caffeine that offer students to be at their optimal performance in their daily task.
