How sugar and caffeine affected my psychology life
Who never like to drink soda or coffee now a days? These two are commonly used and favorite beverages of many people.

Caffeine is produced by plants as an insecticide. It is a drug that acts as a stimulant in humans and causes a raised heart rate, and is used to give more energy in drinks such as tea and coffee, add flavour to drinks such as coke, and in weight-loss foods. A raised heart rate increases the risk of cardiovascular disease as it makes the heart work faster which can wear it out. High levels of caffeine have been linked to increased stress and insomnia, which is also linked to heart disease as it raises blood pressure.
By this definition, and after knowing the effects of caffeine upon the human body, I have come to the conclusion that drinking caffeine is a sign of a lack of respect for oneself, and of an unappreciative attitude toward the life that each of us has been blessed with. Furthermore, it shows of either our inability, or unwillingness to learn to think clearly.

Another negative aspect is that caffeine can have a disruptive effect on your sleep. The most obvious effect of the caffeine is that it can make it hard for you to fall asleep. It can help you stay awake during the day but can also make you stay awake during the night when you are trying to fall asleep.

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. The important thing to remember is that caffeine’s affects vary based on the person, the amount ingested, the frequency of consumption, and individual metabolism.

A lot of people often wonder what caffeine is. When isolated in pure form, caffeine is a white crystalline powder that tastes very bitter. The chief source of pure caffeine is the process of decaffeinating coffee or tea. Caffeine is used to provide“boost energy” or a feeling of heightened alertness. It is often used to stay awake longer and late into the night. Many people feel as though they “cannot function” in the morning without a cup of coffee to provide caffeine and the boost it gives them. Caffeine is an addictive drug. It operates using the same mechanisms that amphetamines, cocaine, and heroin use to stimulate the brain. Caffeine effects are more mild than amphetamines, cocaine, and heroin, but it is manipulating the same channels, and that is one of the things that gives caffeine its addictive qualities. If you feel like you have to have caffeine everyday and cannot live without it, then you are considered addicted to caffeine.
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.

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.

Does one drink caffeine? Caffeine is everywhere, it's in everything, it's apart of our daily lives. That’s what people doesn’t realizes; every soda drink, every cup of coffee, and every energy drink he or she gulps down before a thrilling game, all of that is caffeine.

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
As the vast majority of Americans are addicted to caffeine, studies show that the effects during post-consumption, can be positive or negative depending on the amount and frequency of caffeine intake. As the demand for caffeine has increased, the caffeine industry has increased its amount of marketing and establishments to help aid this demand. Caffeine addiction can lead to serious health and physiological detriments. It is evident that the primary reason for consumption of caffeinated beverages is due to positive effects, such as alertness. The media has an abundance of marketing to continue to illustrate this main effect.
Caffeine is a chemical found in coffee, tea, soft drinks and various easy to get foods and drinks. Like all drugs, caffeine has its good and bad side. Caffeine’s categorized as a stimulant, meaning it temporarily increases alertness and energy. With this stated, you may ask yourself, what’s so bad about a little high associated with coffee or chocolate? I mean it’s practically harmless, right.
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.
Millions of Americans begin each day by consuming the most widely used drug in the United States: Caffeine. Over 90% of United States adults consume caffeinated food or beverages on a daily basis and over 50% take more than the recommended amount. Our innocent daily ritual can turn into an addiction for some because many do not realize that caffeine is even a drug let alone the effects it can have on their bodies. Its use it becoming more and more prominent in our society. It’s not uncommon to walk outside and see a Starbucks or coffee shop on each corner. Innovative foods are coming out infused with coffee, and energy drinks are being pushed at every angle. Caffeine to many is a necessity to wake up in the morning and for others to stay up all night. This is dangerous because people are not only becoming more and more dependent on coffee drinks and energy drinks but they are beginning to ingest more of it each day and are now mixing it with other drugs that can be life threatening. Proper knowledge is important when taking any drug including one that the FDA considers to be a safe multi-purpose food substance and education is the key.
Focus: Many research studies have examined how coffee affects the brain and its functions, and with a healthy diet coffee has many benefits – but also disadvantages.
When a person drinks coffee, the caffeine is absorbed into the bloodstream and then travels to the brain where it blocks an inhibitory neurotransmitter called Adenosine. When this happens, the amount of other neurotransmitters actually increases.
