Benefits of Caffeine
Alertness and Task Performance
Researches also show that caffeine helps people to concentrate longer and do better on simple mental or physical task (Klosterman, 2007). Caffeine gives energy boost that helps the person do routine activities, but that same energy makes it harder to settle down and patiently tackle a complex or new mental challenge (Klosterman, 2007).
Mood Enhancer
One study of more than 86 000 female nurses by research of Harvard Medical School looked for a correlation between caffeine consumption and suicide (Klosterman, 2007). Nurses who drank tow or more cups a day were less likely to become depressed enough to commit suicide (Klosterman, 2007). A similar study were conducted with nearly 130 000

Caffeine acts on the central nervous system by increasing heartbeat and respiration (Kushner, 2006). While caffeine reduces fatigue, it disrupts complex motor task. Caffeine also has effects on sleep (Kushner, 2006). Ingesting caffeine thirty to sixty minutes before going to sleep will dramatically reduce the ability to fall asleep (Kushner, 2006). In fact people who drink as little as two cups of coffee are likely to have their sleep cycles interrupted (Marcovitz, 2006). Even when a person does fall asleep, their quality of sleep was substantially diminished and may still woke up tired (Kushner, 2006).
Caffeine and Dehydration
According to Hal Marcovitz (2006), caffeine is diuretic which causes frequent urination. People who urinate frequently risk dehydration, which is potentially dangerous condition caused by lack of fluids in the body. However, it is rare for most coffee drinkers to suffer from the effects of dehydration such as dizziness, fainting, low blood pressure, and blood in the urine and stool. Dehydration of caffeine reduces waster in the digestive tract that causes constipation. On the other hand taking caffeine with an empty stomach causes diarrhea.

Biochemistry is the study of the chemical composition of living organisms. In regards to caffeine, biochemistry observes the molecule from its living sources such as Coffea arabia and Coffea canephora. Researchers in this area of science study life on a molecular scale. Biochemistry investigates the mechanism of caffeine and how it affects and benefits the human body.
Future of Caffeine According to Bennett Alan Weinberg and Bonnie Bealer (2001)
Chemical intoxicants have been widely enjoyed since the remotest prehistoric times. Today, caffeine is the dominant universal drug of human race. Certainly caffeine use has not remained constant, nor can it be absolutely asserted that its use has demonstrated an unbroken increase in every nation in every decade. Yet coffee bean alone has come to an account for a greater share of international trade than any other agricultural commodity and caffeinated beverages have reached every quarter of every country on earth. Selling caffeinated beverages is and is likely to remain a great
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 ...
By this definition, and after knowing the effects of caffeine upon the human body, I have come to the conclusion that drinking caffeine is a sign of a lack of respect for oneself, and of an unappreciative attitude toward the life that each of us has been blessed with. Furthermore, it shows of either our inability, or unwillingness to learn to think clearly.
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 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.

Caffeine also increases dopamine levels in the same way that amphetamines do (heroine, and cocaine also manipulate dopamine levels by slowing down the rate of dopamine reuptake). Dopamine is a neurotransmitter that, in certain parts of the brain, activates the pleasure center. Caffeine’s effects are obviously much lower than heroin’s, but it is the same mechanism. The long term problem with caffeine is the effect it has on sleep. The half life of caffeine in your body is about 6 hours. That means that if you have a big cup of coffee with 200 mg of caffeine in it at 3:00pm, by 9:00pm about 100 mg of that caffeine is still in your system. You will still be able to fall asleep but your body is going to miss out on the benefits of deep sleep. The next day you are probably going to feel worse, so to make yourself feel better, you will need caffeine as soon as you get up and out of bed. This cycle can start to continue day after day. This is why 90% of Americans consume caffeine everyday. Once you get in the cycle, you have to keep taking the drug (home.howstuffworks.com).
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.
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).
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
Caffeine is the single most widely consumed psychoactive substance in the United States (Einöther & Giesbrecht, 2013). According to Einöther and Giesbrecht (2013), 80% of the world’s population consumes caffeinated products every day, with coffee and tea being the primary sources. In the recent years, the demand for
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.
Coffee is the first thing that people associate with instant energy on a groggy morning. “In the U.S., coffee is king of beverages” (Reinke) Research has been done that has named coffee as an addiction to the people who consume large quantities of it. Coffee was named the top source of antioxidants. This is partly because of the amount consumed each day. Some of the antioxidants that coffee has are quinines and chlorogenic acid. It also contains trigonelline, an antibacterial compound. This is where coffee acquires its delicious aroma. Now let’s step back for a minute and just think about how much caffeine people consume. In an 8oz cup of coffee it has about 85 milligrams of caffeine. This is about double the amount that tea contains. Studies have shown that caffeine stimulates the brain and nervous system. This is where you get that energized feeling. After about the third cup, knees start to bounce, pens are clicking and people start running laps around the office. Caffeine can become addicting if you drink too much. Coffee can become that addictive habit people are unable to shake.
Millions of Americans begin each day by consuming the most widely used drug in the United States: Caffeine. Over 90% of United States adults consume caffeinated food or beverages on a daily basis and over 50% take more than the recommended amount. Our innocent daily ritual can turn into an addiction for some because many do not realize that caffeine is even a drug let alone the effects it can have on their bodies. Its use it becoming more and more prominent in our society. It’s not uncommon to walk outside and see a Starbucks or coffee shop on each corner. Innovative foods are coming out infused with coffee, and energy drinks are being pushed at every angle. Caffeine to many is a necessity to wake up in the morning and for others to stay up all night. This is dangerous because people are not only becoming more and more dependent on coffee drinks and energy drinks but they are beginning to ingest more of it each day and are now mixing it with other drugs that can be life threatening. Proper knowledge is important when taking any drug including one that the FDA considers to be a safe multi-purpose food substance and education is the key.
Preview: The potential effects are related to the main ingredient in coffee – caffeine. Caffeine is a drug that stimulates the central nervous system that increases alertness and energy, but it is also very addictive.
“You usually drink coffee when you are sleep-deprived, right? Well, that much-needed jolt not only keeps you awake, it makes you sharper. CNN reports that coffee allows your brain to work in a much more efficient and smarter way. TIME reporter, Michael Lemonick, says, “When you’re sleep-deprived and you take caffeine, pretty much anything you measure will improve: reaction time, vigilance, attention, logical reasoning — most of the complex functions you associate with intelligence.”(Michael Lemonick) (Jacques,
Biochemistry is the study of the organization and chemical reactions of material in live organisms. Biochemistry became a separate division when scientists mixed biology and different aspects of physical chemistry and started to study the processes of living things, such as energy transfers, hereditary organization, and much more. Biochemistry includes the sciences of neurochemistry, biophysical chemistry, and a very interesting subdivision: forensic chemistry.
