Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it. Caffeine can be found in many products like sodas, tea, and coffee, but it also occurs in several other products such as prescription medications, diuretics, and pain relievers. Caffeine’s widespread use and popularity have caused many people to view the substance as an addictive drug. Thus making caffeine the most inexpensive and readily available drug known to man. Then on the other hand there are people who view caffeine as a helpful stimulant that increases the individual’s concentration and awareness as well as many other physical traits.

Caffeine stimulates the central nervous system. Specifically, caffeine suppresses adenosine, which is an inhibitory neurotransmitter. Adenosine slows neural activity, causing people to become tired. Therefore, when someone drinks caffeine, they do not become tired because caffeine suppresses the adenosine in the brain. Additionally, caffeine causes adrenaline to be released by the pituitary gland, increasing both attention and energy levels. Caffeine also increases the levels of dopamine, glutamate, serotonin, and cortisol in the brain. (McGill University, http://thebrain.mcgill.ca/flash/i/i_03/i_03_m/i_03_m_par/i_03_m_par_cafeine.html), (The Bioneer, http://www.thebioneer.com/caffeine-affects-neurotransmitters-profoundly-changes-brain)
Caffeine raises adrenaline levels and heavy coffee consumption can lead to a state of adrenal gland exhaustion where the adrenal glands are no longer able to adequately respond to stress by releasing enough adrenaline. Adrenal insufficiency can then lead to a host of other problems, including a weakened immune system response, anxiety and panic attacks.
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.
Caffeine functions similarly to the hormone adrenaline (State Government of Victoria, 2014), and increases dopamine levels causing you to feel happy.

As side from that, excess caffeine can also overstimulate the central nervous system, disrupting sleeping patterns. High amounts of caffeine produce negative effect on sleep onset and quality. However, there are large individual differences in the effects of caffeine on sleep. Many people consume coffee during the evening and have no problems falling asleep, while others find that the mild stimulation of caffeine consumed shortly before a bed time delays the time to fall asleep.
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.
