Caffeine Research Paper

Caffeine is a wildly use drug in today’s society. Caffeine is a methylated xanthine which acts as a mild central nervous system stimulant (MS & RL, 2001). It is a stimulant which acts upon the central nervous system and increases alertness, wakefulness and restlessness and it increases the release of catecholamine from renal medullar (Fernandez, 2016; Collines, 2007). It is present in many beverages. Caffeine is found in coffee, tea, soft drinks, products containing chocolate (cocoa) and some medication (Collines, 2007). It is used as a cardiac and respiratory stimulant (Collines, 2007).Caffeine is the most frequently ingested pharmacologically active substance in the world (Collines, 2007).

Druggists have classified caffeine as a stimulant, that can give energize people. Caffeine is also psychoactive, which means that it affects your central nervous system. Caffeine can have some unwanted side effects such as: blood vessels getting smaller which makes it harder to pump blood throughout the body. Many people have medical conditions that can be made worse if they are consuming caffeine. Caffeine has been thought to cause certain types of cancer, thought it haven’t been proven. But the most serious cancer link to caffeine came from one study reported in 1981 that showed people who consumed caffeine had an increased risk of developing pancreatic cancer. Being psychoactive drug caffeine can alter a person’s mood and change their behavior. Caffeine can affect the reproductive and nervous system of men as well as woman. Studies have shown that drinking caffeine can highly increases heart rate and levels of cholesterol.

Caffeine is a central nervous system’s stimulant and is naturally found in more than 60 substances. It is the most universally used central nervous system stimulant as it is found in many dishes, drinks and medication. Health Canada regulates caffeine, when used as an additive, under the Food and Drug Regulations and recommends a limited consumption (Health and Welfare Canada [HWC], 1990).

Heart Disease: A lot of studies have been done on the relationship between caffeine and heart disease. While scientists don't believe it is a primary cause of these diseases, it can make all of them worse. Caffeine raises blood pressure, causes angina attacks and can cause difficulties in those who have murmurs.

The study by Rohers and Roth (2008) looked more in-depth into the relationship of caffeine and sleep quality. The researchers studied the effects of caffeine dependence and the adverse effects they have. Rohers and Roth (2008) concluded that with an intake of high dosage of caffeine, there will be an addiction to it and with the sudden absence of caffeine, withdrawal symptom appears in the form of impaired cognitive function and decreased daily performances. They also mentioned that some participants were prone to administer caffeine themselves than others during the withdrawal period.

If the one-time continuous drinking 2-3 cups of coffee, it would lead to central nervous system hyper-excitability. O 'Keefe, James H., et al. analyzes “Coffee, after water, is the most widely consumed beverage in the United States, and is the principal source of caffeine intake among adults……A daily intake of ∼2 to 3 cups of coffee appears to be safe and is associated with neutral to beneficial effects for most of the studied health outcomes. However, most of the data on coffee’s health effects are based on observational data, with very few randomized, controlled studies, and association does not prove causation. Additionally, the possible advantages of regular coffee consumption have to be weighed against potential risks (which are mostly related to its high caffeine content) including anxiety, insomnia, tremulousness, and palpitations, as well as bone loss and possibly increased risk of fractures. (p.1043-1051)”

Caffeine has a huge effect on the body and mind. It can lead to a kind of addiction. Many people feel like they need caffeine to function in their daily routine. Without caffeine in their system their body may begin to shut down. The most popular beverages in the United States, such as coffee, tea, and soda, contain significant amounts of caffeine. Caffeine is a stimulant and the most commonly used drug in the world. Every day, millions consume it to increase wakefulness, alleviate fatigue, and improve concentration and focus. Other stimulants may have the very similar effects on the body, the symptom similarities are uncanny.

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

It is known for being found in coffee, tea, soft drinks, and chocolate – all drinks and foods that most people do not think twice about taking. Caffeine is considered to be a drug “because it stimulates the central nervous system, causing increased alertness” (“Caffeine”). Most people rely on caffeine, especially in their morning coffee and soft drinks, to maximize their energy levels. However, taking large amounts of caffeine can result in effects of anxiety, dizziness, headaches, and the jitters (“Caffeine”). Self-control is an important aspect in staying within the range that is considered to be safe. I do not consider caffeine to do be a harmful psychoactive substance that should become absent in our life because its effects are not as serious and life threatening. According to the Mayo Clinic, ingesting “more than 500-600 mg of caffeine a day may lead to insomnia, nervousness, restlessness, irritability, an upset stomach, a fast heartbeat and even muscle tremors” (Whiteman). In order for someone to consume that much caffeine, it would be equivalent to drinking approximately 17 Coco-Cola drinks (12 oz.), 30 dark chocolate bars (1 oz.), or 6 brewed coffees (5 oz.). This seems highly unlikely for someone to take in that much caffeine. Abusing caffeine is not as common like other psychoactive

Usually, a dose of caffeine is about 95% excreted within 15 to 35 hours of consumption for an adult; however, newborn infants may need at least 10 days to dispose of 95% of a dose os caffeine. Caffeine’s effects on the cardiovascular system can differ, and depend on the route of administration, does, rate of consumption, and history of exposure to caffeine’s effects. (Korsmeyer and Kranzler).

Many people have consumed caffeine in some sort of way, whether its through coffee, soda or chocolate. However, many of us do not know that it is a highly addictive stimulant. Caffeine is good for increasing alertness, happiness, energy and increased task performance. It does this by stimulating the central nervous system and directly affecting the body’s metabolism. However, having too much caffeine can cause problems such as, but not limited to, insomnia, irregular heart rhythms, dehydration, and headaches.

various studies have looked into the impact of caffeine ingestion on activity execution. The vast majority of them for the most part infer that caffeine utilization before working out appears to broaden continuance execution amid tolerably strenuous vigorous activity. The principle proposed instrument for this change is the expanded utilization of fat as fuel. On the other hand, there is by all accounts advantage errors between constant caffeine clients and non-chronic clients. When a certain level of resistance is come to, the ergogenic impact of caffeine may be lessened (Roberts,2003).

Caffeine, a naturally occurring substance commonly found in coffee, has a mixture of negative and positive effects on the human health. Research shows, that while consuming moderate amounts of caffeine (up to 180ml daily) have no long term effects, over consumption can increase the heart rate, cause headaches and in some cases insomnia ("Caffeine.").

Another big issue with caffeine is that it can become addictive to many people. Like any other drug when you consume too much of it you become tolerant to it. A lot of times after people have drank their coffee in the morning and by the middle of the day when it starts to wear off they tend to reach for another cup this starts to become a terrible cycle because when it comes to sleep you’re not tired anymore. When you keep drinking caffeinated beverages, the body has tons of energy while the chemicals are keeping your body from being tired. The body tends to stay alert. Caffeine creates pretty much the same effect on your body. Once you become dependent on this drug like any other drug you become tolerant to it. When you become tolerant to

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
