Have you ever wondered where the most common thing we see every day comes from? Or how it came to be? After oil, coffee is found to be the most common thing traded in the entire world. Coffee is known everywhere and developed in different ways depending on where you are. According to www.pbs.org “ it is estimated that 2.25 billion cups of coffee are consumed each day worldwide.” Ever wondered why New Yorkers live a very fast paced life and never seem to rest? Its probably because they drink seven times more coffee than any other U.S. city. There are many cool facts about coffee, but the true interesting information is found where coffee comes from and how it got traded throughout the world over time. Every place has adapted coffee and has made it their own.
The exact process by which it affects the body is unknown. It is suspected that caffeine affects the nervous system by altering the perception of effort and exciting the neurons responsible for contracting muscles. It may also be accountable for causing more fat and less...
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, 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...
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
In general, people usually wonder whether the consumption of caffeine is beneficial or harmful to their health. There some benefits and risk of consuming caffeine but based on the different studies that have been conducted over the years, more importance are given to benefits of caffeine (Hensrud, 2014). According to Gunnars (2013), caffeine is good for health as it contains antioxidants and beneficial nutrients which may improve human health. Plus, Gunnars (2013) also stated that studies show that coffee drinkers have a much lower risk of several serious diseases and have proven to have some health benefits. First and foremost, caffeine help people feel less tired, increases memory and increases energy levels. This is because, when caffeine is consumed, it is absorbed into the bloodstream which then travels to the brain and caffeine blocks an inhibitory neurotransmitter in the brain. Then, the amount of other neurotransmitter such as dopamine and noradrenaline increases which leads to enhanced firing of neurons. Therefore, this improves various aspect of brain function such as memory, mood, reaction time, alertness and energy levels (Gunnars, 2013).

Caffeine, also known as methyltheobromine, is a central nervous system stimulant that humans consume on a daily basis. Found in coffee, tea, and other caffeinated beverages, caffeine has many side effects. While caffeine can make the consumer feel more alert, there are health concerns such as dependence and hypertension.
What happen to the caffeine when it is ingested, and what are its consequences? In addressing these questions, there have been many contributors spent much time to prove that caffeine has been shown to behave as an adenosine antagonist to stimulate motor activity, mood and behavior. This antagonist behavior is the basis for an increase in cholinergic and dopaminergic behavior after caffeine intake. Beside of that, the acute administration of caffeine has been reported by several laboratories to elevate brain level of serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA). This increase of serotonin may be associated with the improvement in good mood. Recent studies also show the higher caffeine intake to a lower suicide risk. In this paper, I will investigate the caffeine at a biochemical level and relate its effects on physiological behavior of human with information from the recent research.
A chemical reaction transpires in the brain when drinking caffeine. ‘Caffeine uses the same biochemical mechanisms as other stimulants to stimulate the brain function. It causes increased neuronal firing.’ (chemistryislife.com, 2014) Some effects of caffeine are anxieties and insomnia; this can hits everyone in different ways.
People are renovating new ways to use caffeine all the time. For example two Harvard undergraduates are working on new product called Energy Spray. This new idea is making it to be you don’t need to drink coffee, or an energy drink to obtain the caffeine to wake you up. They decided to make something that you can spray on skin that will be absorbed into your body. Containing water, caffeine, and amino acids this shouldn’t give you the caffeine rush, but giving you a natural feeling of being more awake. Caffeine has shaped everything for office work to physical work. Who knows what the world would be like without it.
Caffeine has been used widely by our modern society to keep up with their hectic lifestyles. One of the many benefits of caffeine is that it increases alertness and prevents fatigue. The main source of caffeine is in the form of coffee, tea, coke and much more. However, due to its addictive characteristics, caffeine is now the most consumed drug all around the globe. Caffeine abuse results in many negative effects such as insomnia, increases blood pressure and heart rate (Pollick, 2010).
Coffee can indeed make people feel more alert and energized, it is an artificial energy boost because caffeine does not create real energy, but rather it is the chemicals that are doing the work
I am going to start with the pros of caffeine. When most people think of caffeine, they think of quick energy, and reduced drowsiness. This is in fact is true, and you may have realized that from using it before.The science behind this has two factors, which both involve your brain. To decrease drowsiness,it blocks your adenosine receptors. Adenosine is the chemical that tells your body that it is tired, which is our body’s way of trying to get us to rest. When we block the receptors, your body stops saying that it is tired, and you feel like you have an energy boost. Another thing that caffeine does is produce dopamine. Dopamine is the chemical that makes you feel happy. The caffeine increases the levels of dopamine being created, and gives your mood a boost too. Caffeine has also been shown to temporarily create other benefits too,such as someones ability to learn, improved reflexes, being able to think clearer and better memory. Regular coffee drinkers were also 80% less likely to develop Parkinson’s disease, which is...
