Beep Beep, Beep Beep! Your alarm is going off, so you roll over and hit snooze. This happens a few times, and before you realize it, it is 7 o’clock. You have 30 minutes before your big biology final, and you’re still groggy and tired. You throw on your clothes and grab a caffeinated beverage of your choice before sprinting out the door. You know you can’t rely on caffeine to stimulate your brain, or can you?
This scenario is very common in the lives of most college students. For most students, caffeine dependency has become more important than sleep. Caffeine seems to be the boost that students need before tests. “Unfortunately, I have no data associating sales trends to midterms and finals, but I think it's safe to assume that sales of caffeinated beverages increase around exam times," claims Buzz Hofford, the general manager of Bon Appetite, a restaurant in the University of Seattle. Since students rely heavily on caffeine, they need to know if caffeine does actually kindle their memory. I believe that caffeine does stimulate the memory process and help boost alertness when used in moderation because of the different types of research that supports caffeine stimulation.
Caffeine comes in many different forms, and is an important in many people’s lives. In order to understand how caffeine has the potential to stimulate the memory, you must understand what caffeine is. Caffeine isn’t sugary or sweet like most substances that contain caffeine. Caffeine is actually a bitter substance, which has many effects on the body’s metabolism (“Caffeine”). It is also a stimulant, meaning it has the ability to increase activity. A survey recently conducted by Johns Hopkins Bay View Medical Center found that 85% of Americans including childre...

...ams or three eight ounce cups of coffee. Excessive amounts of caffeine are considered over 833 milligrams which compares to ten eight ounce cups of coffee (Dugdale). If the amount of caffeine taken is controlled, the negative effects of caffeine will not be experienced.
Even though caffeine does produce some negative effects, its benefits are numerable, especially for college students. Although some studies have proved otherwise, caffeine can stimulate your brain and help boost alertness. Also, caffeine intake in moderation will not induce “crash and burn” effects or cause unorganized brain activity. Caffeine will also help you process information more effectively, which is very import to college students during exam times. So the next time you are clinging to the hope that your caffeinated beverage will keep you attentive for your exam, stay assured that it will.
Caffeine raises your blood pressure when you drink/eat it, raising your blood pressure in general is not a good thing but imagine drinking and/or eating caffeine daily, and your blood pressure constantly rising. Another negative aspect is that caffeine can have a disruptive effect on your sleep. The most obvious effect of the caffeine is that it can make it hard for you to fall asleep. It can help you stay awake during the day but can also make you stay awake during the night when you are trying to fall asleep. You can also have withdraws from caffeine, going back to the story “Java Man” the author Malcolm Gladwell considered it a drug and remember you can get addicted to drugs (you can really get addicted to anything). There are plenty more negative ways caffeine can disrupt your lifestyle but you know what they say for every negative thing you can say there can be some
Caffeine, a central nervous system stimulant, is the main psychoactive ingredient in energy drinks, which enhances alertness and mood, and counteracts symptoms of sleep. There is no doubt ...
Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it. Caffeine can be found in many products like sodas, tea, and coffee, but it also occurs in several other products such as prescription medications, diuretics, and pain relievers. Caffeine’s widespread use and popularity have caused many people to view the substance as an addictive drug. Thus making caffeine the most inexpensive and readily available drug known to man. Then on the other hand there are people who view caffeine as a helpful stimulant that increases the individual’s concentration and awareness as well as many other physical traits. The important thing to remember is that caffeine’s affects vary based on the person, the amount ingested, the frequency of consumption, and individual metabolism.

A lot of people often wonder what caffeine is. When isolated in pure form, caffeine is a white crystalline powder that tastes very bitter. The chief source of pure caffeine is the process of decaffeinating coffee or tea. Caffeine is used to provide“boost energy” or a feeling of heightened alertness. It is often used to stay awake longer and late into the night. Many people feel as though they “cannot function” in the morning without a cup of coffee to provide caffeine and the boost it gives them. Caffeine is an addictive drug. It operates using the same mechanisms that amphetamines, cocaine, and heroin use to stimulate the brain. Caffeine effects are more mild than amphetamines, cocaine, and heroin, but it is manipulating the same channels, and that is one of the things that gives caffeine its addictive qualities. If you feel like you have to have caffeine everyday and cannot live without it, then you are considered addicted to caffeine.
Finals week remains a stressful time for college students. A student may have three to five tests in a matter of four days. However, these tests, unlike most, can be worth up to twenty percent of a semester grade. That is a great amount of pressure on a student. With about six hours of sleep a night, eighteen hours of study never seems like enough. Then again, there may be a solution that allows the student to focus on the study so eighteen hours is enough. Better yet, maybe sleep is unnecessary. This is a reality for the 6.4 percent of college students that use unprescribed Adderall. College students all over the country take Adderall everyday to improve performance in school.
Although individuals try to stop using caffeine, some cannot because it has a strong hold on them and some people can stop. The people that doesn’t stop may fit the clinical definition of caffeine addiction. “In this study, 94% of participants experienced withdrawal when they attempted to stop using caffeine, and 94% continued to use caffeine even though they knew that they might be harming their health with their use.” Women stop taking in caffeine during their pregnancies. Studies suggest, caffeine can be harmful to a growing baby. Most individuals with mental illnesses might be asked to stop taking caffeine. (Caffeine Addiction). All races of women consume 200 milligrams of caffeine daily. They drink coffee, black tea, green tea, and soda. About 89 percent of United States women ages 18 to 34 consume two cups of coffee a day. Even though caffeine affects men more strongly than women, caffeine changes women's estrogen levels; it has different effects in Asian, white, and black women. Studies showed that the effect differ between men and women based on the caffeine intake they consume. Men consume 7 milligrams of caffeine a day. Other men consume 85 to 170 milligrams of caffeine a day. Thirtynine percent does not drink caffeine at all.
Caffeine is the most popular and most widely used stimulant in the world. In Canada, the average person drinks 2.6 cups of coffee a day; that is equivalent to 949 cups of coffee a year. (Van Houtte) Caffeine is a central nervous system stimulant that improves ones attention, focus, and fatigue. When caffeine is ingested it causes your neurons to move at a faster rate, increasing alertness. (Fit Day) Caffeine also binds to the neural receptors, which blocks the adenosine, which prolongs tiredness. Caffeine is a white odorless powder that is most commonly found in coffee, tea, energy drinks, and pops. Caffeine can also be considered and ergogenic aid. Ergogenic aids are external influences that enhance/ improves ones strength, endurance, reaction time and speed of recovery. (Healthline) The three theories that make caffeine an ergogenic aid during exercise is the effect it has on the central nervous system, skeletal muscles, and metabolic changes. (Sheila G. Dean) Caffeine also has a positive effect on an individual’s health, some positive effects include: reduces risk of developing liver cancer, Parkinson’s disease, and Alzheimer’s. (Chawala) Caffeine has been proven to have positive effects on an athlete’s performance, and ones overall health.
Though there are many facets to the subject of sleep, our team has decided to focus on the vital role sleep plays in people’s lives, specifically college students, as well as the numerous methods that can be used to make sleep more effective. Research has consistently proven the importance of a regular sleep schedule. The National Heart, Lung, and Blood Institute promotes this idea, and offers several tips for getting enough sleep while leading a busy life.[1] For instance, it helps to keep the same sleep schedule on weeknights and weekdays. Also, avoiding heavy exercise and artificial bright lights within an hour of going to sleep ensures a more restful sleep. This is especially true for devices like computers and cellphones, the light of which interrupts melatonin production, thus disrupting sleep. Avoiding heavy meals, alcoholic beverages, nicotine, and caffeine within a couple hours of sleeping helps prime the body for a more restful sleep, as well. In fact, the effects of caffeine can last
Many of you might be thinking to yourselves “I must be a drug addict if caffeine is a performance-enhancing drug.”. Caffeine can make you more alert and less tired. This is why many people with wake up in the morning and drink a cup of coffee. Stimulants like caffeine have been used since the times of the Roman gladiators.
Historically, the first behavior of caffeine in the brain to be noticed was the stimulation of the release of caffeine from intracellular storage sites. (Daly, 1999) In research done by Garrett and Griffiths (1997) caffeine was shown to mobilize intracellular calcium by reducing the calcium uptake and stimulating calcium release. Caffeine would attach to a calcium channel in this way activating it and releasing calcium from the "calcium-sensitive" pool.(Daly, 1999) Due to the importance of calcium concentrations for the release of neurotransmitters, Garrett determined, "…mobilization of intracellular calcium has been proposed as a possible mechanism underlying the behavioral effects of caffeine" (p.534).

Johnna Casey COMM 101 12:00 10/18/2017 Preliminary Outline Specific Purpose: To inform my audience of the effects of caffeine on the human body. Central Idea: After consuming caffeine, the central nervous system is stimulated, resulting in a wide array of both positive and negative effects on the human mind and body.
Caffeine is the most common drug ingested by individuals. Caffeine acts as a central nervous system stimulate that gives most people a temporary boost of energy. Caffeine enters the bloodstream through the stomach and small intestine, which in return enables the body to get a boost of energy. Once in the bloodstream, caffeine can persist for several hours. Caffeine is known to increase alertness, increase motivation, increase energy, and exude feelings of euphoria. Habitual caffeine drinkers will experience a reduction in the positive feelings that correlate to caffeine consumption. Once caffeine tolerance is achieved and consumption is halted the body begins to react and people experience behavioral changes. These are known as withdrawal symptoms. A few withdrawal symptoms include headaches, anxiety, fatigue, irritability, sleep disturbance, rapid heartbeat, reduce dexterity coordination, cause insomnia, and dizziness. According to a 2001 Sleep in America poll conducted by the National Sleep Foundation, 43% of Americans are “very likely” to use
As side from that, excess caffeine can also overstimulate the central nervous system, disrupting sleeping patterns. High amounts of caffeine produce negative effect on sleep onset and quality. However, there are large individual differences in the effects of caffeine on sleep. Many people consume coffee during the evening and have no problems falling asleep, while others find that the mild stimulation of caffeine consumed shortly before a bed time delays the time to fall asleep.
Caffeine is one of the most widely consumed stimulants in the world (Evans and Griffiths, 1999). Caffeine in itself comes in many forms, such as coffee, tea, soda, energy drinks and other supplements that are all meant to aid in energy depletion and focus. Caffeine’s practicality and ease of consumption have lent itself to becoming a well-studied stimulant in regards to how it impacts the health of users after extended periods of use. Caffeine is considered an addictive substance with around 100 mg a day leading to dependency (Evans and Griffiths, 1999). In addition to that many substances in which caffeine is consumed have been seen in conjunction with obesity and other health problems (O’Connor, Yang, & Nicklas, 2006). Studies on caffeine
