Caffeine Informative Speech

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 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).

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.

The health effects of caffeine have been extensively studied. The short term side effects of mild caffeine consumption have been identified as headaches, nausea and anxiety. The long term effects of moderate caffeine consumption have been identified as a reduced risk of developing Parkinson’s disease, type 2 diabetes, hepatic diseases and cardiovascular disease. The side effects that caffeine can have on people are both positive and negative.

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.

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

All around the world, people drink coffee, tea and caffeinated drinks to wake up in the morning, to be more vigilant and alert throughout the day. Not only does this keep individuals alert but also allows them to focus and efficiently manage their time throughout their day. This quality of caffeine has caused it to be one of the most highly consumed psychoactive drugs. Individuals who require frequent intakes of Caffeine often feel tired, weak, drowsy if they tend to miss their cup of coffee early in the morning. Although, Caffeine is known for causing wakefulness and alertness it also has its downsides. If a person has a large dose of caffeine in a limited time, the drug could cause them trembling, anxiety and nausea. In long term effects,

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

An increased intake of caffeine affects the body by sending signals for it to produce adrenaline, which gives the consumer a rush or alertness and energy.

Many people start their day with a cup of coffee. According to John Hopkins, “Around 90 percent of Americans consume caffeine every single day in one form or another”. It seems if we need a wakeup call to our morning, many of us grab caffeine to give us that extra boost of energy. Caffeine is a CNS stimulant drug known as trimethylamine. Caffeine is naturally found in chocolate, coffee, and tea. It is also added to drinks such as soda and energy drinks. Caffeine temporarily blocks the adenosine receptors in the brain. These nerve cells can’t sense adenosine in caffeine, therefore, they maintain their activity and keep us alert.

This drug has similar structures to adenosine, which causes drowsiness at the cellular level. Because the two drugs are similar in structure, the caffeine molecule actually attaches to adenosine, inhibiting its ability to cause drowsiness (Villanova). Caffeine is a stimulant drug after all, which can be defined as a drug that raises physiological and nervous activity in the body. Due to the increase in nervous system activity, there are many effects on the nervous system directly. Caffeine directly increases alertness in the brain, causing a greater feeling of being awake and aware, making it a common addition to many medications. Too much caffeine, however, creates headaches. Too much over a long span of time can actually cause the body to develop a tolerance to the drug, which means the body will need more of the same drug to receive the same effect it once had. At this point, withdrawal symptoms can accompany a sudden halt in caffeine intake (Pietrangelo). Researching the effects of this common drug on the central nervous system is significant because of its widespread use worldwide. Our experiment sheds light on the actual effects of caffeine on important aspects of daily life, athletics and intelligence. Using the qualitative and quantitative data collected from the test

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.

It also negatively impacts the body’s sleep cycle. The half-life of one cup of coffee is six hours, this means if you have one cup at 4pm you will still have caffeine in your system at 10pm. This makes it hard to settle down and fall asleep. Even if you do manage to fall asleep it would be difficult to fall into that much needed deep sleep cycle. Which means

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
