The Effects of Caffeine on the Human Body
How does Caffeine affect the human body? Caffeine is the world’s most popular drug (Spiller, 1998), and can be found in over 60 species of plants throughout the world. Consumption of caffeine comes from cola, coffee, cocoa, tea, some medications and so much more. In this paper I will describe the effects of caffeine on the human body, from the health risks to how it can help your body; here are just some of the ways caffeine affects the human body both physically and psychologically. First of all, caffeine has been shown to lead to a loss of minerals found in bones, which eventually will cause osteoporosis, a disease that is characterized by very weak and brittle bones (Liddell, 2011). According to Spiller (1998), “caffeine intake equivalent to 2 or more cups a day was associated with a significantly increased hip fracture risk in woman” (p.351). This is because caffeine decreases the ability of your body to absorb calcium by a small amount. To maintain a proper bone density and drink caffeine regularly, it is important to “aim for three or four daily servings of calcium-rich foods such as milk, cheese and yogurt” (Liddell, 2011).
Caffeine has many Psychological symptoms linked to it as well, such as addiction because caffeine is labeled as a stimulant so overtime people can become addicted to it (Martinez, 2010). Surprisingly you can become physically dependent on caffeine with only taking in doses as low as 100 mg a day (Gaskins, 1998), this is equivalent to 1 cup of coffee or 2 sodas! Also just like any other drug you can become addicted to, “people who are addicted to caffeine will experience withdrawal symptoms when they don't have enough in their system”
Running head: Caffeine and the human body
(Martinez, 2010). Other psychological symptoms that correlate to excessive caffeine ingestion are increased anxiety for those who already have anxiety and sleep

    Caffeine belongs to a class of compounds called methylxanthines and can block a receptor on the surface of heart muscle cells for adenosine. In fact, it is caffeine's blockade of the A1 adenosine receptor in the heart that causes the heart to pound after a significant caffeine dose. Caffeine and similar compounds also inhibit a class of enzymes known as cyclic nucleotide phosphodiesterases. These enzymes are, in part responsible for degrading a stimulatory signal produced when excitatory neurotransmitters activate different neurons in the central nervous system (CNS). Thus, when they are inhibited by caffeine, the stimulatory signal remains active for a longer period of time resulting in a greater sense of alertness (a CNS effect) but also a higher heart rate, blood pressure and respiratory rate. Caffeine also acts as a stimulant drug, causing increased amounts of stimulatory neurotransmitters to be released. At high levels of consumption caffeine has been linked to restlessness, insomnia and anxiety, causing raised stress and blood pressure. This can lead to heart and circulation problems.…

    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.…

    About 85% of Americans consume caffeine in one form or another every single day. Caffeine is found in popular items such as coffee, tea, cola, and chocolate and it has been linked to depressing appetite (Weinberg and Bealer, xvi). Caffeine is America's most popular drug by far and the percentage of Americans that consume caffeine is more than all other drugs put together (Harris, 71). More than half of all American adults consume more than 300 milligrams (mg) of caffeine every day. Many people cannot go through a morning without a cup of coffee because caffeine is an addictive drug. When caffeine was first discovered it was considered a medicine (Weinberg and Bealer, xii).…

    Caffeine is a stimulant which increases cardiac arrhythmia (improper heart rate) by increasing stress hormone (e.g. adrenaline) secretions. It also increases blood pressure which contributes to the blockage of receptors such as adenosine A1 and A2 receptors. The caffeine blocking receptors also blocks vasodilatory function, in which blood vessels become less dilated. Hence wise, caffeine is also known as a mild stimulant of the central nervous system and also stimulates the cardiac muscle and smooth muscles. Caffeine increases levels of neurotransmitters such as norepinephrine has been shown to increase the metabolic rate.…

    That boost we get from that morning cup of coffee is the result of the caffeine that naturally occurs in coffee. Caffeine is a common stimulant and is found not only in coffee and tea, but also in soft drinks and other foods. It can also be bought over-the-counter in tablet form. Too much caffeine can cause anxiousness, headaches, and the "jitters." Caffeine is also addictive and a person who abruptly stops drinking coffee may experience withdrawal symptoms.…

    The benefits of caffeine seem to be really promising, but I fell they are just superficial. The benefits of caffeine are just a mask to the real problem. For instance people drink caffeinated beverages to stay awake for extended periods of time like for studying, long road trips and many other reasons. Caffeine just seems to be a crutch for not sleeping. Caffeine is also used to combat low energy levels which are usually caused by not enough sleep. Caffeine is just like any other drug, it works great the first couple of times, then the more it is used, the greater amount is needed to cause the same effects as the first use. Caffeine is a stimulant type drug; there should be no reason for using caffeine as a quick fix as frequently as Americans do. The beverage industry is thriving on the world’s population having a drug addiction. According to the International Olympic Committee, they are currently list caffeine as a restricted drug. Urinary levels up to a concentration of 12 mg/liter are acceptable, anything above these levels are viewed as deliberate doping, for performance enhancement. (Caffeine and athlete)If the Olympic Committee has reason to ban caffeine from all its athletes then caffeine should be banned from all…

    Caffeine enters the bloodstream through the stomach and small intestine and can have a stimulating effect as soon as 15 minutes after it is consumed. Once in the body, caffeine will persist for several hours: it takes about 6 hours for one half of the caffeine to be eliminated. There are numerous studies to support the idea that caffeine causes physical dependence. If you suspect that you or someone you know is dependent on to caffeine, the best test is to eliminate it and look for signs of withdrawal, such as headache, fatigue and muscle pain.…

    Caffeine In The Brain

    • 3 Pages

    Caffeine is a drug commonly used as a central nervous system stimulant. It is found in plants like coffee and tea. Caffeine can also be found in soft drinks, and it is regarded as the most widely consumed stimulant drug in the world based on Nehlig, Daval, & Debry (1992) research. The interaction of caffeine with adenosine receptors in the brains makes an individual more alert. A moderate intake of caffeine results in small healthy risks while high doses could be a catalyst to negative effects like anxiety, insomnia, and tachycardia. Research has shown that caffeine is widely abused. Clinical data available suggest that withdrawal should be considered as a diagnostic manual in the United States (Reissig et al., 2009). The role adenosine contributes…

    Currently, the FDA has set the level to 400 milligrams (mg) a day for an adult; no set level for children yet. At this point, the medical professional and scientists indicate that it is not a requirement for the FDA to go through the regulatory process to establish other conditions on caffeine use. For example, according to Hart and Ksir (2015), the American Psychiatric Association DSM-5 does not include caffeine as a substance use disorder. DSM-5 advises that there are evidence 2 or 3 cups of coffee may cause a withdrawal such as fatigue. But that it is not clear to what extent the caffeine use is a significant disorder. In other words, DSM-5 does not establish caffeine as a substance of significant disorder because caffeine dependency does not interfere with a person’s capability to work or attend…

    In this study we are interested in assessing the relationship between average amount of caffeine consumed per day and academic performance. We hypothesized that an increase in average caffeine consumed per day would result in increased academic success. A short survey was composed based on average amount of caffeine consumed per day measured in milligrams and academic performance measured by GPA. This survey was administered through Survey Gizmo to Dr. Pleskac’s PSY 395 class, and a total of 59 participants completed the survey. Overall, there was a slight, negative correlation between amount of caffeine consumed per day on average and academic performance. Increases in caffeine consumed on average were negatively correlated with academic performance. From the results of our findings we are unable to provide strong support for our hypothesis that an increased amount of caffeine consumption will lead to increased academic success. Limitations and suggestions for future research are discussed.…
