Caffeine has been one of the more successful drugs that acts as a stimulants ("Caffeine - Drug Prevention & Alcohol Facts - DrugInfo," 2014). Many people consume it for different reason but the majority of them consume caffeine to stimulate their brain to help keep them on their toes throughout the day. Roehrs and Roth (2008) had demonstrated that caffeine indeed plays a role in the sleep and wake time cycle and affects daytime function
Thesis: Caffeine can have many different effects on the body depending on the amount of 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
An independent samples t-test was conducted to examine the difference between experimental conditions on test performance. The results indicated a significant difference between participants who consumed the caffeinated beverage and participants who did not, with participants in the caffeinated group (M = 7.64, SD = 2.41) performing worse than participants in the non-caffeinated group (M = 9.81, SD = 3.16), t (97) = 2.14, p < .05.
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.
Symptoms that follow caffeine consumption are: anxiety, panic attacks, increased heart palpitations, trembling, stress, heartburn, and the deprivation of sleep (Driedger, Doyle par 2). Over time these symptoms can become more severe and eventually will become a major disturbance in one’s life. The anxiety that comes from this can be especially harmful to those who suffer from anxiety disorders, such as GAD-General Anxiety Disorder and Panic Disorder as the caffeine can stimulate a panic attack (Human par 3). The most apparent concern of caffeine consumption, is its effects on teen life. Dr. Jim Lane, a researcher at Duke University stated, “Teens are chronically sleep deprived. Caffeine use might be a consequence of that, and also a cause. Drinking coffee could lead to sleep-onset insomnia, or a delay in going to bed, that contributes to sleep deprivation” (Teens par 7). This shows that as the caffeine trend among teens continue, the link to teen sleep deprivation strengthens. Not only does it prevent the continuation of sleep, but also the process of even falling asleep is delayed. The more deprived of sleep these
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
One on the beneficial effects on caffeine, two the negative effects, and finally on trends in caffeine consumption
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 is consumed in abundance worldwide and is extremely prevalent in today’s society. The average adult in the United States consumes around 300mg of coffee a day, making it clear that caffeine is an important part of many people’s lifestyles (Somogyi 1). Almost all of the caffeine that is consumed is in beverages with coffee as the primary source of caffeine in the U.S. (Somogyi 4). Approximately 75% of adults in the United States consume coffee and 58% consume coffee every day (CDBCNet). Chocolate, tea, and some soft drinks also contain caffeine, but generally not as much as coffee (Somogyi 4). Coffee shops are scattered throughout the world, from small local shops to giant chains. With 20,000 coffee shops in
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.
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
Due to this ability, it is now widely considered an "ergogenic aid", or something that enhances performance. The NCAA is the only organization that restricts the amount of caffeine in an athlete's system by limiting urine concentrations to 15 ug/mL, which equates to ~500mg caffeine or ~6 to 8 cups of coffee 2 to 3 hours before an event. Low doses of caffeine (≤3mg/kg of body weight or ~200mg) have been shown to be ergogenic for a number of sports, and also carry less risk of side effects. When using it to aid performance, caffeine intake should be done gradually and tested in training before used during competitions. Recommended timing and dosage strategies are to consume 1-3 mg/kg about 1 hour before starting training or competition. For example, recommendations for a 50 kg (110 lb.) female would be between 50 mg - 150
This new research would shed light on the adverse impacts of caffeine on normal students vs students already suffering from anxiety. Previous anxiety disorders would be flagged based on the questionnaire which the participants would answer. It is hypothesized that caffeine will have a larger impact on people already suffering from anxiety with effects far beyond the obvious ones, compared to normal people. Given that caffeine is readily available in coffee and soft drinks, and is consumed by a large population of students, conducting this experiment would shed light on the drastic impacts of caffeine on their mental health. The findings would encourage people to reduce their caffeine intake and lower their anxiety levels. Individuals, who consult a psychiatrist for anxiety problem, are always asked about their caffeine intake. Less consumption of caffeine can reduce anxiety levels in most
Caffeine is surrounding us these days, and it is in our everyday lives. We see kids with energy drinks and candy bars, and adults with their daily cup of coffee in their hand. “The US Food and Drug
