Essay On Caffeine

This article discusses the affects caffeine has on several aspects of human health. These included toxicity, cardiovascular effects (arrhythmia, heart rate, cholesterol and BP), bone/calcium balance, behavior, and reproductive and developmental effects. It also discussing the affect caffeine intake has on children and reproductive-aged women.

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 by far one of the most commonly used drugs on the planet. It has many side effects such as it will make you shaky, or hyperactive, it will also deprive you of sleep, cause dehydration, headaches or migraines, addiction, and cause abnormal heart rhythms. These are just a few side effects of caffeine.

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.

Caffeine is found in coffee, tea, soft drinks, chocolate, kola nuts, and certain medicines. Brands of Caffeine include Acetaminophen,Alert-Pep,Anoquan,Butalbital.It makes you jittery and shaky it can cause you to have a hard time falling asleep, staying asleep, or get a sleep it can also cause an increase in heart beat and uneven heart rhythm, It has many more side effect on bodies.Caffeine binds to the adenosine receptor and the cell can no longer identify adenosine because caffeine is taking up all the receptors that adenosine would normally bind to. Caffeine speeds up the nerve cell instead of slowing down like adenosine's effect, Caffeine causes the brain's blood vessels to constrict, because it blocks adenosine's ability to open it.This is why headache medicines contain caffeine ,by it constricting blood vessels in the brain can help stop a vascular

Drinking caffeine can cause you to “temporarily enjoy sharper vision” due to the adrenaline rush and “stimulates the release of dopamine” (Stoddard). Dopamine, a neurotransmitter and is responsible for “learning about rewards” (Newton). It is also commonly known as the “feel-good” hormone. The substance is being studied for “potential benefits in battling Parkinson's disease” (Brian). Parkinson’s disease is a “neurodegenerative brain disorder” that causes the dopamine in the brain to “break down” (WebMD). Studies have shown that “caffeine seems to block a malfunctioning brain signal in Parkinson’s disease”, lessening the severity of the disease (Tessman). These studies have also shown that “people who use caffeine are less likely to develop Parkinson’s disease” (Tessman). Nothing is 100 percent proven as different people have different reactions, but the future of caffeine and medicine is looking bright. Since the drug is so inexpensive and easy to access, it could help many people who could normally not afford the expensive medications that could have the same result. Caffeine can also aid in concentration, making it beneficial to drink while studying for students. It also “opens blood vessels to allow for greater blood flow” supplying the brain and heart with even more oxygen (Ted). With this extra oxygen from the increased blood flow, the brain and heart can work more

Caffeine has become a staple in many developed nations. As a stimulant, caffeine provides a viable solution to many individuals maintaining a busy lifestyle. Particularly in the developed world, individuals tend to work long hours, which creates vast amounts of stress. To help alleviate much of the fatigue that accompanies a busy lifestyle, many individuals elect to drink caffeinated beverages. These beverages range from typical colas to coffee, to energy drinks. Each has its own concentration of caffeine, or energy inducing ingredients. Through the consumption of these beverages, many individuals develop a habit of dependency. Those who consume, often do so in large quantities. Large amounts of caffeine can potentially be harmful to an individual's health when consumed vigorously. Below is a chart from the Specialty Coffee Association of America indicating consumption within America. According to the data compiled in the chart, 172 million Americans consumed coffee on a daily basis.

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

It can cause caffeine induced anxiety disorder causing a person to constantly worry and be unsettled. It is also known to cause hyperactivity and poor sleeping habits due to caffeine blocking chemicals that communicate with the brain. People who drink a lot of caffeine are known to be irritable, and have high anxiety levels and muscle tension. Caffeine can also slow reaction time. When someone drinks caffeine, it stops or slows down chemicals that need to get to the brain, but do not get to the brain causing many problems with the central nervous

Of these eleven listed energy drinks and energy shots, four provide the actual caffeine content on the nutrition label of the can (Red Bull, No Fear, Rip-It, and SK Energy), but many provide the consumer with the broad term energy blend, which gives the consumer little to no useful information except for a broad amount of the combined ingredients within that energy blend. Table 2 (below) provides a detailed overview of the ingredient make up. There are many brands of energy drinks available in the world today that hold a vast array of caffeine within. These energy drinks come in a variety of many sizes as well. Energy drinks are hypothesized to hold a higher content of caffeine than any other caffeinated drink tested and will be the unhealthiest option for an energy source. The results of the experiment will be ranked in order based on the caffeine content for each drink. Through this experiment, the outcomes of consuming energy drinks such as their health effects and risks associated with consumption will be evaluated. The worst type of energy drink in the world is predicted to be the more recent energy shot. Energy shots are believed to hold more health effects and risks because it is such a small dosage that is being consumed in such a short time frame. Energy shots are also believed to hold a much higher caffeine level than any other caffeinated drink. A 2-ounce energy shot can easily exceed the FDA approved level of caffeine intake per day and can also hold up to the same amount of caffeine as a 16-ounce energy drink if not

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).

People ask why is caffeine so appealing? Nutritionists state that kids and teens are not at risk if taken in moderation. However, for adults, they consume it as a drug. They desire it to improve mental and physical performance and mood. Caffeine is considered the most consumed drug in the world. As being a drug, caffeine can cause withdrawal symptoms such as headaches and caffeine dependency. One may say that caffeine should be taken in moderation and can still have the pleasing effects on the central nervous system. If not, it will negatively affect the body mentally and

In larger amounts, caffeine can cause you to have headaches, feel restless and nervous, be unable to sleep, and even - in very large quantities - to have hallucinations.

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

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
