Caffeine is a wildly use drug in today’s society. Caffeine is a methylated xanthine which acts as a mild central nervous system stimulant (MS & RL, 2001). It is a stimulant which acts upon the central nervous system and increases alertness, wakefulness and restlessness and it increases the release of catecholamine from renal medullar (Fernandez, 2016; Collines, 2007). It is present in many beverages. Caffeine is found in coffee, tea, soft drinks, products containing chocolate (cocoa) and some medication (Collines, 2007). It is used as a cardiac and respiratory stimulant (Collines, 2007).Caffeine is the most frequently ingested pharmacologically active substance in the world (Collines, 2007).

Caffeine’s mental appeal is just as trendy as its physical purpose. Caffeine has been proven to stimulate the central nervous system. Caffeine stimulates the Central Nervous System at high levels, like the medulla and cortex, and even has the ability to reach the spinal cord in larger doses. The effect of caffeine in the cortex is a clearer thought process and also can rid the body of fatigue. This gives people a greater ability of concentration for 1-3 hours. For athletes competing in sports where quick thinking and rapid reactions are necessary, caffeine can provide a huge edge. However, these results are much more inconsistent than the experiments done on caffeine in endurance sports. (http://www.garynull.com/Documents/CaffeineEffects.htm)

During the interview I asked the patient how he was feeling physically, to which he replied that she was tired. From this, I asked about her current sleep patterns and the quality of her sleep. She revealed that she was going to bed much later (3-4 am) and as result getting up later in the afternoon. I began to ask more specific questions about things which would affect the patient’s sleep such as the amount of tea and alcohol she was drinking. The patient replied that she drank between 6 and 7 cups of tea a day and switched to wine in the evening. At this point I began to educate her about the influence of caffeine and alcohol on sleep and that she should try to cut

This means caffeine increases brain activity by promotes a state of arousal, alertness and focus. Caffeine is also associated with health and may have some protective effects from cognitive decline because consume caffeine constantly will help activate the brain. (affect of caffeine)

A lot of people have always wondered if caffeine has an affect on your brain. Well, along with your brain, caffeine can also affect many other parts of a person's body. Caffeine mainly has effects on the central nervous system and partly on the brain and muscles. Caffeine can have a negative effect on someone’s mood, actions, memory, how they feel, and on many other factors. “Caffeine is the most widely used mood-altering drug in the world,” says the article, Jittery: Too Much Caffeine can mess with Your Mind. When caffeine is consumed, it pushes out

Caffeine and its Long-term Physiological Changes To many people, caffeine seems like more of a necessity to start the day, or keep the day going, rather than a potentially harmful drug; however, most do not realize the long-term physiological changes that can occur as reported by several users. According to National Geographic, consumers spend 30 million dollars every year on caffeine tablets and roughly 50 billion dollars on caffeinated soda. Caffeine is a drug and as such makes changes the bodies. When people consume food or drink with caffeine in it the body responds by a raise the blood pressure, exciting the central nervous system, endorses urine formation, and speed up the action of the heart

Caffeine (C8H10N4O2) in it chemical nature is a central nervous system stimulant which acts by dilating blood vessels and preventing adenosine from inhibiting the release of glutamate. (Oxford University Press, 2016) Caffeine as a widely used drug, is frequently studied in regards to its performance and physiological effects on an individual. (Harland, 2000)

Many people consume caffeine, some consume multiple servings and various forms of caffeine throughout their day, and it is estimated that more than 85% of Americans consume some form of caffeine every day. Caffeine consumption ranges from being the first thing people drink in the morning, to a late afternoon or evening pick me up; this is mainly due to the fact that caffeine is a stimulant which effects cortisone and adrenaline production both of which the body produces as a reaction to stress. Caffeine is a psychoactive drug and is the most frequently consumed stimulant worldwide. Stimulants are chemicals that heighten the bodies’ nervous and physiological activities such as blood pressure, awareness, heart rate, energy, and

In general, caffeine alters the way our brain communicates to the central nervous system by imitating or changing the release and uptake of neurotransmitters. Caffeine is consumed to awaken and make people alert, however, there are other effects caffeine has on our body. Adenosine, the neurotransmitter that makes us tired, is just one neurotransmitter that is affected by caffeine consumption. For example, if the transmission of dopamine increases, caffeine improves our mood, and may even protect brain cells against age and disease (Weinberg & Bealer, 2015). In addition, if the activity of acetylcholine increases, caffeine increases muscular activity and potentially could improve long-term memory. And lastly, if the level of serotonin adjusts,

The most widely used psychoactive drug in the early twenty-first century is caffeine, which can be found in a broad variety of medication, and dietary sources, including candy, coffee, tea, soft drinks, over-the-counter analgesics, and cold remedies (Korsmeyer and Kranzler). Caffeine is also a derivative of methylxanthine that occurs in most plants globally, and can harm the user even though considered safe by the US Food and Drug Administration (Hoey et al).

Brice, C. F. and Smith, A. P. (2002). Effects of caffeine on mood and performance: a study of realistic consumption.

Caffeine has many negative effects on humans, such as increased heart rate (Lane, J.D., 2002), depression (Goldstein, 2008), and addiction to this “drug.” You may be asking yourself, “What is caffeine?” Well, caffeine is actually a stimulant (Barone, Roberts, 2008) that is found in beverages such as tea, coffee, and soft drinks. In fact, caffeine is the highest grossing and most used stimulant in the United States (Barone, Roberts, 2008). It is estimated that 85% of adults living in the United States consume caffeine on a daily basis (Barone, Roberts, 2008). That means for every 100 adults, 85 of them have had a drink that contained caffeine on any given day. One reason caffeine is so widely available compared to other stimulants is

Research has proven that caffeine affects you brain directly. Studies show that you can rely on caffeine in small doses to jump start your basal forebrain, the part of the brain that processes information (Fisone, Borgkivist, Useillo). It affects a “group of projection neurons located in the striatum, the main receiving area of the basal ganglia” (Fisone, Borgkivist, Useillo). This means that caffeine makes information move faster within the nervous system, which is in direct control of the brain. Researchers at the Radiological Society of North America ran a series of simple tests such as having volunteers answer questions by clicking “yes” and “no” buttons as fast as they could remember the information. The information that each volunteer needed to know was stored in their short-term memory since the information was given to them 12 hours prior to testing. Random volunteers were given caffeine, about the amount of two cups of coffee, and their results were compared to those volunteers that did not have caffeine. In the caffeine condition," the volunteers demonstrated a tendency towards improved short-term memory skills and reaction times during the task (“Coffee Jump-starts
