While caffeine has significant number of positive effects, its negative effects usually go unnoticed. There have been some misperceptions related to the effects of caffeine.
• The early symptoms of acute caffeine poisoning are anorexia, tremors, followed by nausea, vomiting and tachycardia. It can cause rhabdomyolysis and acute renal failure.
• Chronic high-dose caffeine intake may lead to “caffeinism” (irritability, anxiety, insomnia, palpitations, hyperreflexia and so on) [5].
A double-blind placebo-controlled cross-sectional study was undertaken to examine the performance, mood changes, headache, and sleep in over 30 healthy male and female habitual consumers of caffeine. This study revealed that participants were more alert and less fatigued after acute ingestion of caffeine, but felt less alert on chronic exposure. Performance was found to be impaired significantly on abrupt caffeine withdrawal following habitual use [6].
Several studies have shown that caffeine withdrawal or caffeine dependence has significant effects on one’s
Caffeine, a central nervous system stimulant, is the main psychoactive ingredient in energy drinks, which enhances alertness and mood, and counteracts symptoms of sleep. There is no doubt ...
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.
Caffeine (systematic name is 1,3,7-trimethylxanthine or 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione) which is produced in many plants such as coffee beans, tea, cacao beans. On one hand, it is widely used all over the world not only in the human’s dietary such as tea, coffee and chocolate but also can be the pesticides which can be deadly to the insects. On the other hand, caffeine can also harm human’s health in several aspects such as the central nervous system, which is the most common one, the heart rate and the respiration.

Caffeine raises your blood pressure when you drink/eat it, raising your blood pressure in general is not a good thing but imagine drinking and/or eating caffeine daily, and your blood pressure constantly rising. 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.

As America quickly become the most unhealthy nation with approximately sixty-eight percent of adults over twenty classified as overweight or obese, citizens still choose to not find out what they are consuming and how their eating choices can affect their bodies (United States, Behavioral Effects of Caffeine in Children). When examining health, aspects such as calories, weight, and fitness levels are all inspected. Other factors such as the everyday drug that up to ninety percent of people around the world consume in one form or another need to be addressed in an inspection of the national health (“Caffeine” Health Education). Caffeine is a central nervous system stimulant than modifies mood and can be found addictive (“Caffeine” Health Education). American’s average daily intake of caffeine is two hundred and eighty milligrams (“Caffeine” Alcohol and Tobacco). Many people consume much more than that; they are addicted. Caffeine is a drug common in our society that brings negatively affects the the consumer both mentally and physically and the true facts of the substance’s affects stay concealed such as how it affects the heart, brain, and other organs of adults, children, and animals alike.
Caffeine is the most widely used stimulant on college campuses. It stimulates the central nervous system as it temporarily combats drowsiness, and restores alertness. Caffeine’s “powers” are the perfect anecdote for college student’s busy lives, but what if the opposite was true? Whether students barely come into contact with caffeine, and others use it habitually the study researchers whether caffeine has an effect on their cognitive processes. Daily caffeine regulars and sometime users consume it in many different ways, which are coffee, tea, cola drinks, candy bars, cocoa, cold and diet medications, and sleep prevention compounds, and they also consume it in various different doses. Caffeine is in about 100 medications, stimulants like NoDoz, cold preparations, appetite suppressants and mood elevating agents (Addicott, 2009). The psychophysiological effects of the stimulant include alertness, anxiety, heart rate, and these effects can result in a different performance on different task (Acevedo, 1988).

Caffeine has been consumed ever since the 2700 BC, with its conjunction in tea, for the Chinese Emperor Shen Nung.

According to David Weaver, "Caffeine and theophylline are among the most widely consumed neuroactive substances. These drugs are consumed most frequently in beverages, but also are present in certain over-the-counter diet aids, 'alertness tablets' some analgesic preparations, and in chocolate, and are also administered for therapeutic effects." The problem with caffeine is that many students/adults are uneducated about this subject. Stereotypically, caffeine has been labeled harmless. However, most caffeine consumers have no idea how they react to their body chemistry, the chemical mechanism, the hidden side-effects, and the actual daily amount which they intake.

Energy drinks are most famous because of its dangers and health risks. However like most substances it can be risky in the event that it’s not expended with some restraint such as coffee. Even though the arguments against energy drinks are persuasive they don’t have enough legitimate negative effects to be considered harmful, therefore if consumed carefully it can be helpful to its users, despite the health risks. Most people are worried about energy drinks because of its supposed deadly ingredients and they’re effects once it’s consumed in the human body.

Red Bull. 5 Hour Energy. Monster. These energy drinks are becoming increasingly popular not just for teenagers and college kids, but in the world of athletics as well. Athletes around the world are drinking these beverages for a boost in athletic performance and stamina to get an edge over their opponents.

These health risks heavily outweigh the benefits the drinks could possibly bring.

However, there are large individual differences in the effects of caffeine on sleep.
