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 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
Szpak, A. a. (2012, April 2). A case of acute suicidality following excesive caffeine intake. Journal of Psychopharmacology. doi: 10.1177/0269881112442788
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 raises adrenaline levels and heavy coffee consumption can lead to a state of adrenal gland exhaustion where the adrenal glands are no longer able to adequately respond to stress by releasing enough adrenaline. Adrenal insufficiency can then lead to a host of other problems, including a weakened immune system response, anxiety and panic attacks.
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 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.
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
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.
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.
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.
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.
It’s important to watch how much caffeine your body is receiving each day in the foods and drinks you consume. Caffeine is not a bad drug, but be careful to watch for symptoms of withdrawal and caffeine intoxication. It can be dangerous for your body if too much stress is put on it. Remember, there are always decaffeinated options and sometimes these are the best to keep your body healthy.

Lastly, a common side effect of coffee we all may have experienced is the staining of teeth and dehydration. After a while, without proper care coffee can permanently stain and damage your dental. Also the caffeine in coffee is a mild diuretic and can increase the volume of urine excreted. However, this effect can be easily counteracted by the drinking of an extra glass of
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.
When a person drinks coffee, the caffeine is absorbed into the bloodstream and then travels to the brain where it blocks an inhibitory neurotransmitter called Adenosine. When this happens, the amount of other neurotransmitters actually increases.
