According to Adrian Hodgson, a nutritional sport scientist, “Coffee can increase energy through the nervous system causing a person’s body to perform better during activities such as exercising”. Most people fail to realize that for coffee to operate properly in the system the body should always remain in constant movement. In my case, I know once I drink coffee it makes my body hot and once I begin to get warm I tend to get sleepy quickly.

Adrenal insufficiency can then lead to a host of other problems, including a weakened immune system response, anxiety and panic attacks.
Although individuals try to stop using caffeine, some cannot because it has a strong hold on them and some people can stop. The people that doesn’t stop may fit the clinical definition of caffeine addiction. “In this study, 94% of participants experienced withdrawal when they attempted to stop using caffeine, and 94% continued to use caffeine even though they knew that they might be harming their health with their use.” Women stop taking in caffeine during their pregnancies. Studies suggest, caffeine can be harmful to a growing baby. Most individuals with mental illnesses might be asked to stop taking caffeine. (Caffeine Addiction). All races of women consume 200 milligrams of caffeine daily. They drink coffee, black tea, green tea, and soda. About 89 percent of United States women ages 18 to 34 consume two cups of coffee a day. Even though caffeine affects men more strongly than women, caffeine changes women's estrogen levels; it has different effects in Asian, white, and black women. Studies showed that the effect differ between men and women based on the caffeine intake they consume. Men consume 7 milligrams of caffeine a day. Other men consume 85 to 170 milligrams of caffeine a day. Thirtynine percent does not drink caffeine at all.
Caffeine is the most popular and most widely used stimulant in the world. In Canada, the average person drinks 2.6 cups of coffee a day; that is equivalent to 949 cups of coffee a year. (Van Houtte) Caffeine is a central nervous system stimulant that improves ones attention, focus, and fatigue. When caffeine is ingested it causes your neurons to move at a faster rate, increasing alertness. (Fit Day) Caffeine also binds to the neural receptors, which blocks the adenosine, which prolongs tiredness. Caffeine is a white odorless powder that is most commonly found in coffee, tea, energy drinks, and pops. Caffeine can also be considered and ergogenic aid. Ergogenic aids are external influences that enhance/ improves ones strength, endurance, reaction time and speed of recovery. (Healthline) The three theories that make caffeine an ergogenic aid during exercise is the effect it has on the central nervous system, skeletal muscles, and metabolic changes. (Sheila G. Dean) Caffeine also has a positive effect on an individual’s health, some positive effects include: reduces risk of developing liver cancer, Parkinson’s disease, and Alzheimer’s. (Chawala) Caffeine has been proven to have positive effects on an athlete’s performance, and ones overall health.
Scrutiny of caffeine and its effects has increased dramatically in the last 20 years, due in part to an increase in consumption of caffeine. In fact, coffee consumption among young adults rose to 3.2 cups per day in 2008 from 2.4 cups per day in 2005 (Rokerya 1). For instance, in a one hour period, on Richland College’s on-campus Starbucks, the author took note of how many customers arrived and purchased a cup of coffee. Between 8:00 and 9:00 AM, there were 51 customers, implying that – especially at college - many people are dependent on coffee in the mornings. However, the results from these studies are inconclusive and often somewhat contradictory – many studies (such as that by Tetsuya Ohara et al.) show that caffeine is a great boon to
Two similar, but separate studies were conducted. The first study (A) used 12 highly trained athletes, either triathletes or cyclists. The second study (B) used a smaller sample of 8 athletes with similar backgrounds. While training histories were similar, caffeine intake histories varied from occasional to regular intake of up to ~150 mg/day (2mg/Kg). Subjects first performed a maximal incremental power test to determine their VO2 peak, a measurement of the body's ability to taken in O2 and turn it into work. A work rate of ...
Scientists Ricardo Mora-Rodriguez and Jesus G Pallares executed a study observing the performance outcomes and side effects of energy drinks. They confirmed that due to their high carbohydrate concentration and lack of salts, energy drinks are not a good beverage choice when prolonged exercise in a warm environment is likely to require rehydration. They also found that ingestion of high doses of caffeine, although ergogenic, could result in negative side effects that could counteract the caffeine’s ergogenic effect. Even though energy drinks have the ability to increase a certain amount of energy, the energy would be short lived, due to lack of hydration. A similar study was performed by a team of scientists in Nepal. They tested on medical students at a Nepalese medical school. After the experiment, they concluded that energy drinks give energy and increase the stamina but they produce neurologic, psychiatric, cardiovascular and gastrointestinal complications on health. Certain students that participated in the study started to experience palpitation (increased or irregular heartbeat), nausea, constipation, and abdominal pain. These symptoms are just a few of the health risks that regularly consuming energy drinks can
The media fails to project the negative effects of excessive caffeine intake. This literature review will illustrate how excessive caffeine consumption can be detrimental to one’s life, and how problematic caffeine use derives from conditioning by the caffeine industry. Caffeine is the single most widely consumed psychoactive substance in the United States (Einöther & Giesbrecht, 2013). According to Einöther and Giesbrecht (2013), 80% of the world’s population consumes caffeinated products every day, with coffee and tea being the primary sources. In the recent years, the demand for coffee has increased, causing the caffeine industry to create an expansion of coffee shops, new caffeinated beverages (Bailey, Saldanha, Gahche, & Dwyer, 2014), and mass-media advertising.
Coffee is the first thing that people associate with instant energy on a groggy morning. “In the U.S., coffee is king of beverages” (Reinke) Research has been done that has named coffee as an addiction to the people who consume large quantities of it. Coffee was named the top source of antioxidants. This is partly because of the amount consumed each day. Some of the antioxidants that coffee has are quinines and chlorogenic acid. It also contains trigonelline, an antibacterial compound. This is where coffee acquires its delicious aroma. Now let’s step back for a minute and just think about how much caffeine people consume. In an 8oz cup of coffee it has about 85 milligrams of caffeine. This is about double the amount that tea contains. Studies have shown that caffeine stimulates the brain and nervous system. This is where you get that energized feeling. After about the third cup, knees start to bounce, pens are clicking and people start running laps around the office. Caffeine can become addicting if you drink too much. Coffee can become that addictive habit people are unable to shake.
