As a college student having to wake at five in the morning, and going home at 6 in the evening, it doesn’t take a scientist to realize that at a young age, pressures are being force down on us, it hard to stay awake or active without doing anything to hype ourselves up. Adults expects us to become punctual, neat, and most of all to be ready for anything that college throws at us, but how can we do that when we can’t even sleep a full 7-8 hours of sleep. As our minds become fully aware of consequences of deadlines for assignments, projects, or even research paper, as students who are afraid of failing and causes us to take in a high dose of caffeine in the middle of the night really helps a lot. So instead of drinking those energy drinks that …show more content…
Caffeine empowers the central nervous system, decreasing our view of exertion so we feel that we can proceed at longer pace for more periods (2011, Peterson). Caffeine is a stimulant. It gives you the additional stamina needed to push through extreme exercises and expands your heart rate, enhancing blood stream from the heart to whatever is left of your body. Coffee is external influences that enhance athletic performances, helps to eliminate or to assist you with performing troublesome physical task and reduces fatigue. It additionally expands the measure of adrenaline in your framework, bringing on a surge of additional glucose and oxygen to your muscles. Coffee has been found to help with any sorts of activity such as perseverance exercises like a marathon or Iron Man rivalry, and short, control escalated exercises enduring around 4 to 8 minutes (n,d.). However, consistent use of coffee will cancel out all the benefits said, and will cause more harm to the body. It’s advisable to drink coffee an hour before a
In order to function normally, “adequate sleep is a biological necessity” (Austin 34). College is a transition for many students, and without prioritizing many can become sleep deprived. There are various reasons that college students could become deprived of sleep. Reasons include loud roommates, sororities/fraternities, late night jobs, and procrastination. Additionally, a student could be struggling financially or academically, and this could be possible causes for keeping one up late at night. Little to no sleep could affect how young adults function leading to multiple effects. Depression can be a result of not getting enough rest, and the “longer this
It is true that sleep deprivation is a widespread issue, generally resulting from early start times. It is also a serious one; according to a study by Harvard Medical School, sleep deprivation can lead to issues such as obesity, heart disease, difficulty learning, and can genuinely shorten a person’s lifespan. As Robbins explains, teenagers have a different internal sleep clock than other age groups. It is most healthy for students in high school to go to bed around 11 and wake up around 9. Since school often begins as early as 7, students are told they simply need to go to bed early, around 8 or 9 PM. This contention does not take into account the fact that humans are biologically not wired this way, and it's virtually impossible for most teens to fall asleep this early. It also doesn't take into account that with clubs, sports, church, volunteering, other extracurriculars and hours of homework, students often struggle to start their homework before their suggested “bedtime”. It is contended that students can control their own schedules so that they can get more sleep. However, pressure from parents and peers to get into a “good” college can cloud students’ perceptions of what is right for them, making them choose to overwork themselves in order to build impressive resumes. I myself can identify with this phenomenon. During the weekdays alone, I volunteer two nights a
Caffeine has many specific benefits for different types of athletes. Though much of the research on caffeine in athletics is inconclusive, there are many athletes that believe the substance can enhance their physical as well as mental performance. It is supposed that caffeine can improve the athlete’s endurance in sports where long-term stamina is needed. These sports include cycling, running, and even soccer. In an experiment to study the effects of caffeine as an ergogenic aid, 6 regular caffeine users were monitored while they exercised until exhaustion. During this double ...
Caffeine, commonly found in coffee and many other beverages, and containing certain chemicals compounds leading to the constant necessity of fidgeting, jitters, sleepless hours, and health hazards as though being tormented by a hobgoblin with the irresistible sweet aroma and multiple flavors trapping you into a path, not being able to truly quit as desired or consequences attached, but is it the world’s most used legal drug addiction or something enjoyable, you decide? “The delicious chemical in caffeine is 1,3,7-trimethylxanthine”(Linn). “Caffeine is made by pressuring cooking beans with CO2 to produce the drug in powder form”(Linn). “In caffeine the consumption breakdown in Coffee is 54%, Tea it’s 43%, Food and misc it’s 3% and used as a common mood-altering drug in the world, most popular way of ingesting is through coffee”(Linn). The issue with drinking coffee is due to the fact that caffeine can cause some troubling effects like insomnia activity in the brain that prevents sleep, constant need to urinate leading to dehydration due to the lack of fluids in the body, and diarrhea causing the food right out because it accelerates the digestion in the stomach. The consumption of too much caffeine can cause damage in human health also causing an overdose leading to death. The impact in society is through how much caffeine Americans consume daily, and the effects it causes in human health and sleep patterns. Throughout the years past caffeine consumption in America has increased jarasicaly, about 90% in some form daily. “On average Americans have been known to consume 280 mg of caffeine per day or 2-3 cups of coffee”(Linn). Strangely enough, caffeine is still contained and found in decaffei...
America lives and breathes off of a drug, a drug that the American people consume every day. This drug is found in your soda, your tea, and your coffee. The drug is caffeine. Caffeine has many properties that make it useful to all of us; it has many negative uses. Caffeine has many negative effects. It is addictive like Oxycodone; however, many people believe that the positive effects outweigh the negative. Caffeine helped shape this world and it has provided medical help to those that have a disorder. On the other hand, caffeine is what drives us in the Twenty-First Century and it changes our brain’s chemistry. How do we decide if caffeine is truly an unknown weapon of destruction for the better or worse?
“When the going gets tough, the tough take a nap.” This statement by Tom Hodgkinson perfectly describes the solution to the life of the average American high schooler, who wakes up early, rushes to school, and undergoes several grueling classes, only to later participate in extracurricular activities and return home to complete homework. Due to all these activities, only a vast minority of teenagers obtain the amount of sleep they need in a night; Tom Hodgkinson’s quote proposes a solution to this problem. By instituting naptime in high schools, students could simply nap to refresh themselves when the going gets tough, whether that be an excessive amount of homework, an extremely demanding test, or a sports practice that lasts long into the
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 ...
Caffeine, also known as methyltheobromine, is a central nervous system stimulant that humans consume on a daily basis. Found in coffee, tea, and other caffeinated beverages, caffeine has many side effects. While caffeine can make the consumer feel more alert, there are health concerns such as dependence and hypertension.
Most people aren’t aware that caffeine can act as a stimulant to the central nervous system. So once someone consumes a caffeinated beverage they may begin to notice a slight change in the way their body begins to feel. Caffeine can be found in many different places such as energy drinks, coffee, candy and also in other common beverages and over the counter medications. Caffeine can have major side effects on those who consume it on a regular routine, but caffeine can also have side effects on those who rarely even consume caffeine . “These side effects include sleep deprivation, nausea, cramping, anxiety, fatigue, and headaches (Braun 73).” Not only does drinking a couple of caffeinated beverages come with its list of side effects, caffeine consumption has also been proven to show drastic changes in the kidneys. “Also, caffeine has been known to weaken the detrusor muscles in the bladder, which provokes the need to urinate (Chambers 42).” So once a person has been consuming caffeine past a certain period of time it begins to become difficult for them to regulate their trips to the bathroom. The list of harm caffeine does on the human body could continue forever, but I will review some of the most relevant categories. Caffeine can have harmful effects on the human body that people are not aware of, therefore I believe that people should be informed what exactly caffeine is and how it affects them directly in terms of where caffeine can be found, the effects it has on the brain and the heart and also the pregnancy effects. Also, people should be provided with a general knowledge of how caffeine can play a part in someone’s life, and some steps to help slow down the consumption of caffeine.
Consumption of 1000–1500 mg per day is associated with a condition known as caffeinism. Caffeinism usually combines caffeine dependency with a wide range of unpleasant physical and mental conditions including nervousness, irritability, restlessness, insomnia, headaches, and heart palpitations after caffeine use. Caffeine blocks the neurotransmitter adenosine, which acts as an inhibitor of the other neurotransmitters. “When adenosine flows normally through the brain, it slows down the brain and body… When adenosine is blocked, the brain and body become more alert and active (Marcovitz 33).” Caffeine from coffee or other beverages is absorbed by the small intestine within 45 minutes of ingestion and then distributed throughout all tissues of the body. Peak blood concentration is reached within one hour. The biological half-life of caffeine the time required for the body to eliminate one-half of the total amount of caffeine varies widely among individuals according to such factors as age, liver function, pregnancy, some concurrent medications, and the level of enzymes in the liver needed for caffeine metabolism. It can also be significantly altered by drugs or hormonal states. In healthy adults, caffeine's half-life has been measured with a ra...
Research shows that sleep is a necessity in order for someone to be able to perform at their maximum potential. College students are no exception to the rule and are often at a greater risk to suffer from conditions that accompany sleep deprivation. Regardless of the time period, a college student must be well rested in order to perform at his or her best in terms of physical performance, memorization capabilities, and test-taking abilities. Also, without adequate sleep, the person will be more susceptible to illnesses, both mental and physical. In conclusion, I believe that sleep deprivation among college students is extremely common and has a direct effect on how well that student will perform or feel.
In the world of higher education, students at the collegiate level are highly likely to be overwhelmed with course load, in addition to sports and extra-curricular activities (Jacobs & Dodd, 2003). These factors have the potential to lead to various amounts of sleep deprivation, and as the research of Nilsson, Sunderstrom, Karlsson et al. (2004) has shown, sleep deprivation is correlated with higher levels of fatigue, impairments in speed and accuracy as well as limitations in cognitive and physical performances. One way to cope with this fatigue that has shown to have very positive results on people of all ages is taking naps. In addition to reducing sleepiness, Milner & Cote (2008) have determined that “napping may lead to considerable benefits in terms of mood, alertness and cognitive performances”. It is these benefits that nappers seek when engaging in napping activities.
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.
Fifty six percent of students report being tired throughout the school day, which can lead to missed information and confusion (Wysong). According to this statistic, over half the students in class are not going to achieve their maximum learning potential in school. In order to avoid this problem, a teenager's brain typically needs to sleep from 11:00 pm to 8:00 am (“High schools starting later to help sleepy teens”). However, most high schools require students to be in class as early as 7:15 or 7:30 am. As a result, many adolescents simply do not have the opportunity to get enough rest. Changing the traditional school time to start later in the day will benefit adolescent sleep cycles, promote learning, and prevent disease by regulating the body. Ideally,...
It has been proven to prevent diseases and improve physical and mental ability. Fruits and vegetables also have tons of antioxidants but our bodies seem to absorb the most from coffee. Nutrients from the coffee bean are infused into the drink such as, Riboflavin (Vitamin B2), Pantothenic Acid (Vitamin B5), Manganese and Potassium, Magnesium and Niacin. These beneficial elements can help boost athletic performance, if taken at the right time before a workout. Caffeine increases the number of fatty acids in the bloodstream, which allows athletes' muscles to absorb and burn those fats for fuel, therefore saving the body's small reserves of carbohydrates for later on in the exercise.
