Caffeine Research Paper

Caffeine causes a dependency, rather than an addiction. Because you can go through withdrawal, and become irritable without it, it is a dependency, but is not necessarily an addiction. Caffeine increases dopamine levels, similar to the way addictive drugs do, but those cause extreme chemical unbalance in one’s brain,

Central Idea: Caffeine can be found in many places and comes in many forms. It can major effects on our body and we can experience major withdrawal symptoms.

Caffeine is found in many plant species, where it acts as a natural pesticide. It is found most commonly in cocoa, tea and coffee, but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans, caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure, restlessness, insomnia and anxiety which, in the long term, can lead to heart and circulation problems.

Caffeine is a natural product that is extracted from the raw fruit of coffee plants over sixty creased alertness. Caffeine gives most people a temporary energy boost and elevates mood..species to be exact. kola nuts, cocoa, yerba maté, guarana berries, coffee beans and teas contain this. Caffeine is rapidly absorbed in about 30 to 60 minutes in our bodies after ingestion. Caffeine is defined as a drug because it stimulates the central nervous system, causing increased alertness. Caffeine gives most people a temporary energy boost and elevates mood.caffeine can also be in things like over the counter medications, and pain relievers.

Caffeine is in tea, coffee, chocolate, many soft drinks,and pain relievers and other over-the-counter medications. In its natural form, caffeine tastes very bitter. But most caffeinated drinks have gone through enough processing to camouflage the bitter taste. Many people feel that caffeine increases their mental alertness. Higher doses of caffeine can cause anxiety, dizziness, headaches, and the jitters. Caffeine can also interfere with normal sleep. Caffeine in extreme cases could cause stroke, liver failure, and even

Caffeine disguises as adenosine in the brain. Adenosine tells your body to slow down when it’s time to sleep. The caffeine gets into the bloodstream and stimulates the central nervous system. Way over a week caffeine causes a person to become more alert, react faster, and feel like the person is not working as hard. Caffeine can also cause reduced brain growth. It causes someone’s mind to race and makes it hard for them to concentrate. A person does not get a burst of energy directly from caffeine. It blocks the message from your brain to your body that you are tired. Caffeine blocks off the want to sleep and rest. The result of this is the rise of alertness and wakefulness caused by the release of dopamine and glutamate. Caffeine in a person's body modifies the brain's capability to make good, healthy choices by moving function to the lower part of the brain from the upper part of the brain. Concerning other parts of the body, caffeine can cause both high heart rate and blood pressure. Caffeine can impact

In today’s society, coffee has become the most prevalent and usual source of energization that many individuals turn to when they need vitality. Even though coffee is the most prominent, caffeine can also be found inside sodas, teas, and even energy drinks. Caffeine is a psychoactive drug that stimulates the central nervous system. A typical cup of coffee encompasses about ninety-five milligrams of caffeine. Studies have been performed to observe the effects of caffeine and how it effects so many individuals. For an instance, some studies have discovered that the effects of caffeine may be different for some individuals depending on individual differences such as level of fatigue (Oei & Hartley 2005). These effects lead people to

In 1819, the German chemist Friedlieb Ferdinand Runge isolated relatively pure caffeine for the first time; he called it "Kaffebase”. Before the popular use of caffeine people were much less alert to the world. “Caffeine usage dates back to the Stone Age when it is believed that they consumed coffee berries and beans. Around 600 B.C. the Chinese began using the leaves of the bush Camellia sinensis to brew tea, which is the first recorded caffeinated beverage… As Europe began trading with Asia the popularity of tea tremendously expands (Marcovitz 12).” Because caffeine is a psychoactive drug, it is often regulated. In the United States the Food and Drug Administration (FDA) restricts beverages to containing less than 0.02% caffeine. Historically, coffee thus caffeine was illegal for some classes in Mecca in parts of the 16th century, and in the Ottoman empire Charles II of England tried to ban it in 1676, Frederick II of Prussia banned it in 1777, and coffee was banned in Sweden in the years 1756–1769, 1794–1796, 1799–1802, and 1817–1823. The bans on coffee have often had religious, economic, or political reasons rather than being based on concerns for the well-being of the population. Some religions believe that

Caffeine is a pharmacological agent, a drug, which can lead to physical dependence if people use it on a daily basis. It has been reported that after only a week of daily caffeine consumption, people experience side effects such as, headaches, fatigue, decreased alertness and drowsiness, when they try to stop their consumption (Evans & Griffiths, 1999).

One of the most popular sources of caffeine today is tea. The first tea cup was brewed in 2732 B.C. Dried leaves landed in a boiling cup of water and served to the Chinese Emperor Shen Hung. From China, the idea of tea had spread throughout the world. There is a variety of different types of tea. Lipton, Green Tea, Black Tea, Brewed Tea, and even tea from your favorite beverage places such as Starbucks and Dutch Bros.

A small percentage of the population relies on caffeine to be able to feel like themselves and they have become physically dependent on it. These people develop a caffeine use disorder, also known as a caffeine addiction. Without caffeine some addicts will start to go through withdrawals. "This can trigger symptoms such as headache, fatigue, drowsiness, depression, irritability, concentration difficulties, nausea and vomiting." (Whiteman, 2015) Dependence of the caffeine can become so severe that the addicts are unable to reduce the intake of the caffeine knowing that the physical or psychological issues or problems from the caffeine will

When we wake up in the morning, many of us reach for a cup of coffee to kick-start our day. When we hit that afternoon slump, again, many of us turn to coffee as a pick me up. While coffee beans and coffee are the most common sources, caffeine is found naturally in several other leaves, seeds and fruits including tea leaves, cacao seeds and kola nuts. It can also occur as a food additive in processed foods such as instant coffee, tea, chocolate, most colas, candies, energy drinks, bars, chocolate, and chewing gum. To add, caffeine is an ingredient in many over-the-counter medications, such as pain relievers, diet pills and cold remedies. The amount of caffeine in foods and drinks depends on the brand, the type of beans or leaves used, how it is prepared and how long it steeps. According to the US Food and Drug Administration (FDA), the average American drinks between two and four 8 oz. cups of coffee per day (~300mg

Many of us find ourselves drinking a freshly brewed cup of coffee, an ice cold soft drink, a hot cup of tea, or an energy drink whether it be in the morning, afternoon, or in the night but one thing is that they all share a common ingredient: Caffeine

Just as there are positive effects from caffeine there are also negative effects. Caffeine is addictive. If you are a dedicated daily coffee drinker and one day decide to give it up you will have withdrawal side effects which could include: headaches, anxiety, agitation, and restlessness.

Caffeine has many negative effects on humans, such as increased heart rate (Lane, J.D., 2002), depression (Goldstein, 2008), and addiction to this “drug.” You may be asking yourself, “What is caffeine?” Well, caffeine is actually a stimulant (Barone, Roberts, 2008) that is found in beverages such as tea, coffee, and soft drinks. In fact, caffeine is the highest grossing and most used stimulant in the United States (Barone, Roberts, 2008). It is estimated that 85% of adults living in the United States consume caffeine on a daily basis (Barone, Roberts, 2008). That means for every 100 adults, 85 of them have had a drink that contained caffeine on any given day. One reason caffeine is so widely available compared to other stimulants is
