Caffeine is the most widely used drug in the world and the consumption in humans is constantly growing. Caffeine is found in a lot of the consumables that are ingested on a daily basis (Nawrot P., et al). Research claims that an appropriate and healthy daily intake of caffeine is approximately 400 milligrams. Research also shows that a large amount of caffeine intake a day has been proven to lead to several cardiovascular

Fortunately, the current examination has shown coffee to continue a of good health choice, as lengthy as one is not topping more than 3 topping-bout a day. This guideline is based on the deed that the cardinal element found in coffee is a intermix called caffeine. Caffeine is a of nature intermix made from more than 50 vegetable sources. While caffeine in undue amount has been linked to some increased freedom from disease

Thesis: Caffeine can have many different effects on the body depending on the amount of consumption.

Premiere Hospital of Newport Beach (PHNB) is concerned about providing caffeinated coffee to patients waiting to be seen in their waiting room. Other hospitals serve it, but PHNB wants to make an informed decision around this based scientific inquiry. The big question for hospital administration is whether caffeinated drinks have a significant impact on heart rates. The research is aimed at evaluating

In the fast paced life of a college student, it is not uncommon for tasks and due dates to quickly pile up, demanding more hours studying and less hours sleeping. Any amount of sleep deprivation can lead students to consume caffeinated beverages, particularly coffee, to help them stay awake and get their work done. According to the University of Michigan (2015), Caffeine acts in the body by effecting the central nervous system and may start to

About 9 million metric tons of caffeine are consumed around the world every year. That’s equal to the weight of 1243 Eiffel towers. Most of this caffeine is consumed in coffee and tea, but it’s also ingested in some sodas, chocolate, caffeine pills, and even beverages labeled “decaf.” Caffeine helps us feel alert, focused, happy, and energetic, even if we haven’t had enough sleep, but it can also raise our blood pressure and make us feel anxious. It’s the world’s most widely used drug…so how does it keep us awake?

Even though I do not possess a caffeine produced disease, I have experienced the consequences of drinking high amounts of caffeine which includes anxiety, insomnia, gastritis, colitis, mild tremors, and irritability. Although small quantities of caffeine may not substantially cause serious problems, if consumed in high quantities (>400mg.), it might worse the conditions of an anxiety disorder, diarrhea, bipolar disorder, bleeding disorders, heart conditions, diabetes, glaucoma, osteoporosis, epilepsy, irritable bowel syndrome, and high blood pressure (webmd, 2009). In addition to the consequences of caffeine mentioned above, new studies have linked caffeine to psychotic symptoms (Grimson, 2011). At the moment, I do not suffer any of the diseases previously mentioned, but I do have a family history of diabetes, depression, and anxiety disorders. Thus, the predisposition to any of the risks of a high caffeine intake increases. In summary, the consequences of consuming high doses of caffeine vary from person to person, and it may elicit different effects, which may range from a mild change of mood to a complex psychotic break; therefore I considered quitting caffeine an optimum choice for a healthier

The primary literature article is titled, Dose–response study of caffeine effects on cerebral functional activity with a specific focus on dependence. This article consists of many parts including an abstract, introduction, materials and methods, and results. The articles aim is to explain the physiological functions of caffeine and how it affects the brain. The language used in this article is very specific and scientific. It consists of very precise word choice and both quantitative and qualitative information. In the introduction, this article mentions that the average daily caffeine consumption for all adult consumers and from all sources reaches 2.4–4.0 mg/kg for a 60–70 kg subject in the United States, UK and Canada (Nehlig and Boyet, 2000). This excerpt from the

Caffeine has become an integral part of most Americans lives, making it “America's most popular drug by far” (Brian). Most of the country will enjoy a cup of coffee in the morning or a few sodas during the day. Although most of the world’s population consumes caffeine in either coffee, tea, chocolate, energy drinks or sodas, the majority of those people are undereducated about the drug. There are many drawbacks to the drug, but also many benefits.

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.

Thesis: Caffeine is something that almost everyone has consumed and some people are even addicted to. Caffeine has negative and positive effects on one’s health

One on the beneficial effects on caffeine, two the negative effects, and finally on trends in caffeine consumption

One part of the human body that too much consumption of caffeine can affect negatively the your heart. Caffeine speeds up your brain cells, which speeds up your heart beat in the process. Too much caffeine will also raise your blood pressure. Caffeine using adults were polled on their stress levels given a 1 to 5 rating, with 5 being the most stressful. With each stress rating, each adult averaged a 1.7/0.4 mm Hg in blood pressure, and 1.8 beats per minute more in heart rate than adults in the lower stress rating (Lane, J.D., 2002). With further testing, they found that stress level and caffeine went hand in hand, with the highest caffeine users being the ones with 5 stress ratings. This study showed that consuming caffeinated beverages raises your blood pressure and heart rate by a considerable amount. In the same study as above, they used 500 mg of caffeine (close to 4 cups of coffee) to see how much it raised a person’s blood pressure throughout a single day. On average a person’s blood pressure was 4 mm Hg higher during than day than on a normal
