The Effects Of Caffeine On Human Health

This article discusses the affects caffeine has on several aspects of human health. These included toxicity, cardiovascular effects (arrhythmia, heart rate, cholesterol and BP), bone/calcium balance, behavior, and reproductive and developmental effects. It also discussing the affect caffeine intake has on children and reproductive-aged women.

Besides the obvious and immediate effects of drinks containing high amounts of caffeine there are a few long-term benefits worth mentioning. Depression is a horrible condition that slowly eats away at a person until there is nothing left of them. Coffee has been shown to fight depression ("Does Caffeine Reduce the Risk of Depression?). By drinking a few cups of coffee or one can of an energy drink chances of depression

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)

Caffeine is a natural central nervous system stimulant. It is considered a drug that if is overly consumed can be dangerous for one’s body. Caffeine is a temporary energy booster that improves mood and alertness for most people, mainly athletes. It can be an eye-opener in the morning, could be drunk or eaten on practice brakes, and for some, it just became a habit that they cannot go through a day without a cup of coffee before exiting their doorways. Furthermore, it requires good health and stamina for athletes to perform throughout the game, particularly the one in teams,

Caffeine is one of the most consumed psychoactive substances around the world. Caffeine is not bad for health, some researchers even show positive effects. Caffeine appears to reduce fatigue. And in this way also has an indirect effect on decision. Regarding cognitive function, caffeine has an effect on reaction time. Some studies also show a positive effect on long-term memory.

In the fast paced life of a college student, it is not uncommon for tasks and due dates to quickly pile up, demanding more hours studying and less hours sleeping. Any amount of sleep deprivation can lead students to consume caffeinated beverages, particularly coffee, to help them stay awake and get their work done. According to the University of Michigan (2015), Caffeine acts in the body by effecting the central nervous system and may start to

Caffeine is a substance found in coffee, tea and most sodas. When it is consumed, it is a mild stimulant. The energy drink, Monster, contains caffeine, which has the ability to manipulate adenosine (adrenaline), a substance present in the brain that is used to transmit brain signals to different parts of the body. Adenosine causes an increase in alertness and awareness. Modern studies show that there is direct benefits of the so-called “caffeine kick” that is experienced by drinkers.

How does caffeine work in the body to create such effects? Caffeine is absorbed quickly from the GI tract, and is significantly elevated in the blood in 15 minutes, with peak concentration at 60 minutes. It passes through the blood-brain barrier and affects brain centers leading to an increase in alertness and decrease in fatigue and drowsiness. It stimulates the nervous system, affects respiration, boosts energy levels and thereby is beneficial at enhancing sports performance. Caffeine helps to mobilize fat stores so the body can use it as a primary fuel source, thus sparing glycogen. The delay in depletion of muscle glycogen

This caused many athletes to begin using caffeinated products in physical sports competition in order to enhance their abilities. The reason that many consider caffeine to improve physical activity is due to the fact that caffeine naturally provides the body with energy and decreasing pain and fatigue. While performing any physical activity the body uses energy that has been stored inside, so with the excess energy provided from the caffeine the body is able to exert more power and energy allowing the physical performer to work longer and with more strength. Decreasing fatigue is one of the other benefits that may aid in the physical performance of the consumer. Caffeine is thought to affect physical performance by stimulating fat oxidation, which, in turn, spares muscle glycogen stores. This means that caffeine is somewhat forcing the body to burn the necessary energy needed to conduct the physical activity from the body’s fat rather than the muscles, this allows the physical performer to continue for longer, farther, and with more force output. If caffeine can decrease naturally occurring pain of exercise and sustain or increase firing rates of motor units, a greater force output should be maintained (Davis 824). It, being caffeine, may also enhance muscle contractions, and increase tolerance to fatigue through the production

Many people start their day with a cup of coffee. According to John Hopkins, “Around 90 percent of Americans consume caffeine every single day in one form or another”. It seems if we need a wakeup call to our morning, many of us grab caffeine to give us that extra boost of energy. Caffeine is a CNS stimulant drug known as trimethylamine. Caffeine is naturally found in chocolate, coffee, and tea. It is also added to drinks such as soda and energy drinks. Caffeine temporarily blocks the adenosine receptors in the brain. These nerve cells can’t sense adenosine in caffeine, therefore, they maintain their activity and keep us alert.

Caffeine works by binding itself to the chemical element, adenosine. Adenosine works as a natural depressant in the body, preparing your body for rest. When caffeine binds to adenosine, it excites the cell and blocks the absorption of adenosine into the brain. This causes the rush of energy many people rely on to stay awake. However, high usage of caffeine will result in the brain producing more adenosine to counter the stimulant. Because of the extra production of adenosine, tolerance is built; this means more doses of caffeine will have to

Just as there are positive effects from caffeine there are also negative effects. Caffeine is addictive. If you are a dedicated daily coffee drinker and one day decide to give it up you will have withdrawal side effects which could include: headaches, anxiety, agitation, and restlessness.

Effects of Caffeine Supplementation On Strength and Muscular Performance in Recreationally Trained Males Student Researcher: Gregory Grabowski Allied Health Sciences University of Connecticut Abstract: Pre-workout and caffeine containing supplementation has become very popular for weight lifters to increase focus, strength and muscle growth. There are many side effects from consuming large amounts of caffeine such as anxiety, nervousness and insomnia. The purpose of this study is to determine whether caffeine increases strength in recreationally trained males. The experiment will utilize a randomized, double-blinded, crossover design in which 30 recreationally trained males between the ages of 20 and 34 years will participate in. They will

Ever stay up late studying for a test or exam and wake up exhausted? Or just experienced a long day and need an extra boost? Many people believe caffeine is the answer to anyone’s drained state of being. Healthline.com explains that, “Caffeine reaches your brain quickly and acts as a central nervous system stimulant.” Caffeine is commonly referred to the most widely used drug on the planet, so the next question is which caffeine-filled product is the most efficient? It is widely debated whether energy drinks or coffee can provide the best balance of caffeine, flavor, and other ingredients, but after researching, I have come to conclude coffee is superlative in all aspects.

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
