III. Attention Getter
Many of us find ourselves drinking a freshly brewed cup of coffee, an ice-cold soft drink, a hot cup of tea, or an energy drink whether it be in the morning, afternoon, or in the night but one thing is that they all share a common ingredient: Caffeine

(Transition: First I will talk to you about the beneficial effects of caffeine).
V. Main point 1: Beneficial Effects of Caffeine
A. Caffeine can increase mental alertness while doing educational or work tasks.
B. In addition to alertness and mental performance, caffeine may also improve memory and reasoning in sleep-deprived people.
C. Research by Smith 2001, shows that 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.
D. 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).
E. According to Gilliam 2008, the effect of caffeine on mood depends on the amount consumed and the individual's dependence and tolerance. For
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 is the most widely used drug in the world and the consumption in humans is constantly growing. Caffeine is found in a lot of the consumables that are ingested on a daily basis (Nawrot P., et al). Research claims that an appropriate and healthy daily intake of caffeine is approximately 400 milligrams. Research also shows that a large amount of caffeine intake a day has been proven to lead to several cardiovascular
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
- The high long-term consumption of caffeine is associated with a lower risk of cardiovascular disease and diabetes.
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
3. Mental performance, low doses of caffeine 20-200mg has positive mood effects, such as increased happiness and well-being.
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.
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
Central Idea: Caffeine can be found in many places and comes in many forms. It can major effects on our body and we can experience major withdrawal symptoms.
The consumption of caffeine can increase alertness, reaction speed, vigilance, the ability to concentrate and problem-solving ability; all the things Red Bull Energy Drink also claims to do (Red Bull 2013).
Caffeine is demarcated as a drug because it arouses the central nervous system, causing increased alertness. Caffeine gives most people a temporary energy boost and elevates mood. That’s why everyone generally uses it for plenty of reasons mostly dealing with work or school. Some people use caffeinated energy drinks to improve their endurance while playing sports or to dance for long periods. That’s just the beginning, these are the things that caffeine does to the brain, heart, fetus, and body.
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).
E. Ingesting around 200 mg a day of caffeine can boost long term memory (Whitemen, 2015).
According to energyfiend.com a study in Japan showed that caffeine increases memory and has been shown to decrease the rate of Alzheimer’s. This study also showed that caffeine can decrease depression by increasing Dopamine (A mood altering hormone) in the brain. With the increase in production of Dopamine, daily intake of caffeine has also been shown to decrease the rate of Parkinson’s disease.
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.
