The Effects of Caffeine
Works Cited Not Included
Caffeine has played a central role in many cultures. Coffee was first
discovered over 1000 years ago, and approximately 75% of Americans
drink coffee on a regular basis. Despite the thousand years that have
passed, there is still controversy surrounding the biological effects
of coffee and it's primary active ingredient, caffeine. Caffeine is
the most widely used stimulant drug in the world, usually ingested in
the form of coffee, tea, soft-drinks, and chocolate. (Honig) Caffeine
is derived from a bean or from tea leaves and can be found in the
seeds or fruits of more then 60 species worldwide.(American Academy)
Caffeine has numerous effects and it is disputed whether caffeine is
overall beneficial or harmful.
Caffeine is a naturally occurring xanthine (precursor to uric acid
often found in urine) used as a central nervous system (CNS) and
respiratory stimulant, or as a mild diuretic. Other xanthine
derivatives include the bronchodilator theophylline and theobromine, a
compound found in cocoa and chocolate. Caffeine is a mild, but direct
stimulant at all levels of the CNS that quickens the heart and
cardiovascular system as well. The related xanthine, theophylline,
share these characteristics and are used in the treatment of pulmonary
disease. Both caffeine and theophylline are CNS stimulants, with
theophylline exerting more dramatic effects than caffeine at higher
concentrations. Caffeine also stimulates the medullary respiratory
center and relaxes bronchial smooth muscle. Caffeine stimulate...

Many studies have suggested a relationship between chronic caffeine
use and a number of diseases. However, the cause-and-effect evidence
is difficult to prove because of lifestyle variables among the
subjects in the studies (eg. smoking, alcohol consumption, exercise),
differences in genetic inheritance, form of caffeine intake (coffee,
tea, sodas), and the presence of other biologically active substances
in the beverage. (Brice) The consumption of caffeine does have side
effects, some negative and some positive, but it is clear that when
taken in moderation caffeine is never adverse to ones health. However,
caffeine consumers should be aware of withdrawal and keep themselves
up to date on the latest caffeine research.
The effects on caffeine during pregnancy were explained and detailed. I explained the causes and effects on caffeine and the major dangers that affect the offspring. Caffeine is the most dangerous cause of danger in pregnancy and their offspring. It can infect the metabolism, the fetal, and can cause miscarriages. The blood flow can easily be decreased by having to much caffeine and can in danger the baby.
Caffeine, probably the most widely used drug, is a potent pharmacological and psychotropic agent. The white, bitter-tasting, crystalline substance was first isolated from coffee in 1820. The origins of the words, caffeine and coffee, reflect the spread of the beverage into Europe via Arabia and Turkey form North-East Africa, where coffee trees were cultivated in the 6th century. Coffee began to be popular in Europe in the 17th century, and plantation had been established in Indonesia and the West Indies by the 18th century. Nowadays, it is a regular component of the diet for most people. Caffeine is considered as a cheap drug that could be found in many nature sources such as tea, chocolate, and cocoa.
Scrutiny of caffeine and its effects has increased dramatically in the last 20 years, due in part to an increase in consumption of caffeine. In fact, coffee consumption among young adults rose to 3.2 cups per day in 2008 from 2.4 cups per day in 2005 (Rokerya 1). For instance, in a one hour period, on Richland College’s on-campus Starbucks, the author took note of how many customers arrived and purchased a cup of coffee. Between 8:00 and 9:00 AM, there were 51 customers, implying that – especially at college - many people are dependent on coffee in the mornings. However, the results from these studies are inconclusive and often somewhat contradictory – many studies (such as that by Tetsuya Ohara et al.) show that caffeine is a great boon to
Does one drink caffeine? Caffeine is everywhere, it's in everything, it's apart of our daily lives. That’s what people doesn’t realizes; every soda drink, every cup of coffee, and every energy drink he or she gulps down before a thrilling game, all of that is caffeine. Caffeine is only completed when he or she get addicted. Caffeine can be an exceptional threat to the human body; energy drinks for example, it has enough caffeine to kill someone if he or she drinks enough. Energy drinks has been the number one drink high school students drink to stay awake in school; they even bring the drink in classrooms, and more than one energy drink. Soda has enough caffeine to destroy ones inner body. Soda is a everyday drink for some individuals, they
Caffeine functions similarly to the hormone adrenaline (State Government of Victoria, 2014), and increases dopamine levels causing you to feel happy. It blocks adenosine receptors, which prevents you from feeling drowsy (Staci, 2012). Caffeine also stimulates the brain, improves comprehension, memory, reflexes, and the clarity of thoughts (Important Facts About Caffeine, 2011).
Caffeine, commonly found in coffee and many other beverages, and containing certain chemicals compounds leading to the constant necessity of fidgeting, jitters, sleepless hours, and health hazards as though being tormented by a hobgoblin with the irresistible sweet aroma and multiple flavors trapping you into a path, not being able to truly quit as desired or consequences attached, but is it the world’s most used legal drug addiction or something enjoyable, you decide? “The delicious chemical in caffeine is 1,3,7-trimethylxanthine”(Linn). “Caffeine is made by pressuring cooking beans with CO2 to produce the drug in powder form”(Linn). “In caffeine the consumption breakdown in Coffee is 54%, Tea it’s 43%, Food and misc it’s 3% and used as a common mood-altering drug in the world, most popular way of ingesting is through coffee”(Linn). The issue with drinking coffee is due to the fact that caffeine can cause some troubling effects like insomnia activity in the brain that prevents sleep, constant need to urinate leading to dehydration due to the lack of fluids in the body, and diarrhea causing the food right out because it accelerates the digestion in the stomach. The consumption of too much caffeine can cause damage in human health also causing an overdose leading to death. The impact in society is through how much caffeine Americans consume daily, and the effects it causes in human health and sleep patterns. Throughout the years past caffeine consumption in America has increased jarasicaly, about 90% in some form daily. “On average Americans have been known to consume 280 mg of caffeine per day or 2-3 cups of coffee”(Linn). Strangely enough, caffeine is still contained and found in decaffei...
America lives and breathes off of a drug, a drug that the American people consume every day. This drug is found in your soda, your tea, and your coffee. The drug is caffeine. Caffeine has many properties that make it useful to all of us; it has many negative uses. Caffeine has many negative effects. It is addictive like Oxycodone; however, many people believe that the positive effects outweigh the negative. Caffeine helped shape this world and it has provided medical help to those that have a disorder. On the other hand, caffeine is what drives us in the Twenty-First Century and it changes our brain’s chemistry. How do we decide if caffeine is truly an unknown weapon of destruction for the better or worse?
Waking up to a hot cup of coffee, relishing the cool tingling sensation of a cola with your lunch, or relaxing in the afternoon over a cup of tea, all have similar ingredient caffeine. Caffeine has been consumed ever since the 2700 BC, with its conjunction in tea, for the Chinese Emperor Shen Nung. In 575 AD, the first use of coffee beans where in Africa where it was used as currency and food. Even more today, caffeine consumption has become an integral part of millions of people's daily lives. According to David Weaver, "Caffeine and theophylline are among the most widely consumed neuroactive substances. These drugs are consumed most frequently in beverages, but also are present in certain over-the-counter diet aids, 'alertness tablets' some analgesic preparations, and in chocolate, and are also administered for therapeutic effects." The problem with caffeine is that many students/adults are uneducated about this subject. Stereotypically, caffeine has been labeled harmless. However, most caffeine consumers have no idea how they react to their body chemistry, the chemical mechanism, the hidden side-effects, and the actual daily amount which they intake.
Introduction: Caffeine is one of man’s most successful discoveries, dating back to the 13th century. Although its origins are not completely clear, we see the impact of its use down to the 21st century. From local cafes and restaurants to schools and fast food chains, the evidence is clear that coffee is truly everywhere in our society. One of coffee's many uses was that it had the ability to make its consumers feel more ready to start the day. However, does caffeine really affect our moods and emotions?
Caffeine is a plant product, and it is a stimulant that acts on the central nervous system. It is commonly found in coffee, soft drinks, and chocolate. (University of Michigan - University Health Service, https://www.uhs.umich.edu/caffeine)
Caffeine is a molecule that has many characteristics of cocaine and heroin. This is so because the all make people hyper and crazy. The chemical formula is C8H10N4O2. The atoms in the Caffeine carbon, hydrogen, nitrogen,and oxygen.
When I was challenged with giving up a habit, food or something I rely on for a 72-hour period I initially drew a mental blank. Eventually I settled on giving up caffeine. This proved to be quite a challenge since I rely on heavy doses of caffeine to help me throughout the day. Usually, I prefer to use caffeine Monday through Friday in an attempt to jump start my work productivity. After giving up caffeine for 72 hours I noticed some initial changes in my routine, some benefits without caffeine and also some drawbacks without caffeine included in my morning routine.
In the everyday life, people consume a large dose of caffeine in their routines, including coffee and tea, Consumers have not knowingly consumed the caffeine without regards of its effects to their health and wellbeing. Some effects however can heighten performance, which is believed to be linked to its effects on the aerobic capacity. This aerobic capacity refers to the amount of oxygen the body can distribute to the muscles and cells, also known as VO2max. During physical activity, the amount of oxygen needed to sustain the muscles and cells are increased, which forces the heart to pump blood harder and faster (Duncker & Bache, 2008). Current studies of the effects of caffeine shows its relationship to the heart, as the consumption of
As the vast majority of Americans are addicted to caffeine, studies show that the effects during post-consumption, can be positive or negative depending on the amount and frequency of caffeine intake. As the demand for caffeine has increased, the caffeine industry has increased its amount of marketing and establishments to help aid this demand. Caffeine addiction can lead to serious health detriments and physiological detriments. It is evident that the primary reason for consumption of caffeinated beverages is due to positive effects, such as alertness. The media has an abundance of marketing to continue to illustrate this main effect. The media fails to project the negative effects of excessive caffeine intake. This literature review will illustrate how excessive caffeine consumption can be detrimental to one’s life, and how problematic caffeine use derives from conditioning by the caffeine industries.
Past research found that the early studies on the effects of caffeine on cognitive performance were often too small to detect general group effects (Smit & Rogers, 2000). This study will utilize college students, both undergraduate and graduate, to broaden the study. It was also found that caffeine consumption may be correlated with the amount of hours of sleep people get each night, which may also influence students’ academic achievement (Smit & Rogers, 2000). High doses of caffeine in the late evening increases the time taken for some individuals to go to sleep, which also results in fewer sleeping hours. The effects of caffeine on sleep can vary from individual to individual, and even when sleep is affected there is no clear evidence
