How Does Caffeine Affect The Human Body

For centuries, products containing caffeine have been used in order to stay awake, enhance physical performance, or simply just for the taste of it. However, how does caffeine really affect your body and the activities that you perform, both physically and mentally? Caffeine is the most used drug in the world being that it is found in coffee, tea, chocolate, soda beverages, and much more. Some research shows that caffeine has aided the body by enhancing the physical endurance activities by at least 12% (Jenkins 1). This caused many athletes to begin using caffeinated products in physical sports competition in order to enhance their abilities. This forced major sports facilities to ban the use of caffeinated products before athletes perform.

Caffeine is one of the most prevalent drugs consumed around the world, and is frequently used by athletes in efforts to enhance their performance. It is defined by the Medical Dictionary as “A bitter white alkaloid, C8H10N4O2 that stimulates the central nervous system and body metabolism” (2010). Some believe that increasing their caffeine intake will then improve their energy and endurance levels during long-term sporting events such as running, biking, or swimming. Caffeine is found in an assortment of foods and drinks including but not limited to coffee, tea, cokes and cola products, chocolate and energy drinks. Caffeine can also be found in some over-the-counter medications.

Caffeine is the most popular mood altering drug in the world. 54% of Americans over the age of 18 drink coffee on a daily basis (Coffee By the Numbers). There are a wide range of drinks that have caffeine in them besides coffee as well, including energy drinks, tea, coffee, and soda. It is used daily to make us more alert . But besides it actually being a drug, it affects the human body positively when given in moderate doses but like any other drug, it has negative effects too. Caffeine not only positively affects the brain and the body, but by taking too much it causes negative effects like higher blood pressure and caffeine withdrawal.

Lastly, Caffeine has a long history of use and can be found in many common foods, drinks, and medications. Although caffeine has been the subject of pharmacological studies for several decades, the mechanism of action of its effects on the central nervous system have only recently been defined as a blockade of adenosine receptors (Choi et al., 1988; Fredholm, 1985; Snyder, 1984). Extensive reviews of caffeine (Dews, 1984; Weiss and Laties, 1962) conclude that its stimulant properties are weak in comparison with those of other drugs (e.g., amphetamine) and that its effects are modest, making detection of these effects difficult and generalizations cumbersome. Dews (1984), however, states that the following three effects are clear: (1) it has the tendency to postpone sleep; (2) it reduces the degradation of performance because of fatigue and boredom; and (3) it decreases hand steadiness. The interpretation distilled from these and other reviews is that caffeine's effects are significant primarily when performance of repetitive, nonintellectual tasks is partially degraded.

Everyone knows the feeling of waking up and making that morning cup of coffee to help

Even though caffeine is widely accepted, it has also been seen as a negative substance in the United States due to unhealthy effects to the human body. With the rise in the energy drink market and an increase in the consumption of caffeinated beverages, doctors and scientists are becoming concerned with the amount of caffeine that teens are consuming. Recent studies have shown that teens and young adults have a very unhealthy and unbalanced diet which is mainly due to the many unhealthy options offered to them. Students are often bombarded with the endless amount of choices such as fast food restaurants, snacks and drinks. Many of these choices contain unhealthy amounts of sugar, fat and cholesterol. Teens going through puberty and adolescence

Caffeine is the most generally utilized stimulant, caffeine, is found in espresso, tea, jazzed soda pops and caffeinated drinks, Inaba and Cohen (2007). Caffeine is a crystalline intensify that is discovered particularly in tea and espresso plants and is a stimulant of the focal sensory system. Just about all Americans use caffeine in some kind of way, and some are just addicted to that they got to have it on the regular

America is fueled by caffeine on a daily basis; it is what keeps us reved up and awake in a life full of tasks to accomplish. What exactly is caffeine though? The FDA states that, “Caffeine is probably the most frequently ingested pharmacologically active substance in the world. According to Scientific Nation, it is formed when a “xanthine and a methyl group come together.” A central nervous system stimulant, it occurs naturally in more than 60 plants, including coffee beans, tea leaves, kola nuts used to flavor soft drinks and cocoa pods used in making chocolates.” Furthermore, caffeine is also added to many things like gum, water and medicines as a stimulant. Unfortunately, many, including myself, love caffeine but the negative side effects that it can have on our body should make you wonder if it is worth it. I will explore just a few of the side effects that too much caffeine can have on our body when not used in moderation.

For many of us coffee has always been an essential to start the day. That double shot of caffeine in the morning wakes you up and keeps you going, alert and focused. There are substantial benefits to drinking coffee and that caffeine boost; however, do you know what caffeine really does to your body? Learn about the potential side effects and possible damage to your health before sipping that fifth cup mid-day.

Caffeine is an addictive stimulant that has a pharmacological effect on the central nervous system. It can also affect muscle movement. When ingested caffeine can improve alertness or cause agitation. Caffeine is chemically classified as a part of the Xanthine group. It is a naturally occurring Methylxanthine. Caffeine acts as an adenosine (role in cellular energy transfer, and the synthesis of RNA) receptor antagonist with psychotropic (mind and emotion affecters) and anti-inflammatory activities.

Caffeine, a naturally occurring substance commonly found in coffee, has a mixture of negative and positive effects on the human health. Research shows, that while consuming moderate amounts of caffeine (up to 180ml daily) have no long term effects, over consumption can increase the heart rate, cause headaches and in some cases insomnia ("Caffeine.").

Caffeine is a chemical found in the leaves, seeds, and fruit of over 60 species of plant. It is found in coffee, tea, some soft drinks, and chocolate. It can also be taken as a tablet at high doses in products such as No-Doz or Vivarin (Donahue,33). It is banned as an ergogenic aid in large doses.

A cheese burger would not be complete without a tall glass of soda. The fuzzy bubbles accentuate the taste of beef and fries dipped in ketchup. Before the burger is devoured, the cup of pop sits empty. Time for a refill. By the time the meal is over, the Styrofoam cup has been emptied three times. “I paid for this, so I might as well enjoy it at home.” The words slip through burps as soda floods the container. Many people are caught in the trap of sugary, caffeinated beverages at restaurants, movie theaters, gas stations, and various other places. But the people who absent mindedly sip the drink, and they are unaware of how the caffeinated beverage affects their body. Caffeinated beverages lead to negative effects on the body such

Caffeine is an alkaloid that is found naturally in things such as nuts, leaves, and seeds. Caffeine is also known as 1,3,7-Trimethylxanthine, Thein, Methylbromine, Guaranine, Cafeina, Coffeinum N, Coffeinum Purrum, Dexitax, and Durvitan. The molecular weight of caffeine is 194.194 g/mol. The chemical formula for caffeine is C8H10N4O2. Caffeine also acts as an adenosine receptor protagonist. (PubChem.gov, 2004) Friedrich Ferdinand Runge was the first person to isolate caffeine. (Helmenstine, 2017) Caffeine is typically found in these plants: coffee plants, guarana, yerba mate, cacao

Caffeine is the most consumed drug in the world and coffee is the second most traded commodity, next to oil. Origins of its use date back to the eleventh century. It is commonly known for being a stimulant: a substance that raises levels of physiological or nervous activity in the body. Caffeine is also a diuretic as it increases the activity of the cardiovascular system, which increases heart rate and blood pressure. Thus the renal system encounters a higher volume of blood to filter, resulting in waste output. However, recent research shows only high quantities of caffeine produced significantly more urine volume. Another misconception about caffeine is that it is dehydrating. In actuality, it only has a dehydrating effect when consumed in high quantities and when an individual is deprived of other fluids. Other ingredients in caffeinated foods and beverages, such as taurine, are responsible for dehydration.
