Anxiety Disorders: Caffeine And Its Effects On The Body

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.

Central Idea: Caffeine can be found in many places and comes in many forms. It can major effects on our body and we can experience major withdrawal symptoms.

Drawbacks: The Mayo Clinic states that “consuming more than 500-600 mg of caffeine a day may lead to insomnia, nervousness, restlessness, irritability, an upset stomach, a fast heartbeat, and even muscle tremors” (2014). These negative effects greatly depend on the amount of caffeine that you

Caffeine is found in many plant species, where it acts as a natural pesticide. It is found most commonly in cocoa, tea and coffee, but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans, caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure, restlessness, insomnia and anxiety which, in the long term, can lead to heart and circulation problems.

The nervous system is the first to use it as a stimulant, however the risk of too much, or too little, can cause anxiety attacks, confusion, and hallucinations. Next, it travels to your stomach, which can be extremely dangerous if you ingest too much, caffeine rises the stomach acid amount. The term used by (Healthline Networks, Inc.) is diuretic, which triggers your body to get rid of water. After the caffeine is absorbed through your stomach it enters the bloodstream, which gives you the short burst of jittery-ness and irregular heartbeat increase. Caffeine truly reaches all parts of your body, causing the effect to last longer with higher

The health effects of caffeine have been extensively studied. The short term side effects of mild caffeine consumption have been identified as headaches, nausea and anxiety. The long term effects of moderate caffeine consumption have been identified as a reduced risk of developing Parkinson’s disease, type 2 diabetes, hepatic diseases and cardiovascular disease. The side effects that caffeine can have on people are both positive and negative.

It might make you feel better and more alert, but it can also raise your heart rate and blood pressure, cause increased urination or diarrhea, and contribute to insomnia and anxiety. Plus, the foods and beverages caffeine is found in have their own impacts on your body that have to be taken into account.

"People often perceive the stimulating effects of caffeine as beneficial for boosting energy and alertness" (pg 151). The amount of consumption also plays a large role in whether or not there would be significant affects in brain chemistry. A daily consumer would have changes in brain chemistry which would cause changes in mood, lower energy levels, lack of focus and even have physical affects like headaches. Sudden disuse of the drug could then cause an individual to be short with people or not perform as well at work on or a general basis.

Caffeine is by far one of the most commonly used drugs on the planet. It has many side effects such as it will make you shaky, or hyperactive, it will also deprive you of sleep, cause dehydration, headaches or migraines, addiction, and cause abnormal heart rhythms. These are just a few side effects of caffeine.

Caffeine is found in coffee, tea, soft drinks, chocolate, kola nuts, and certain medicines. Brands of Caffeine include Acetaminophen,Alert-Pep,Anoquan,Butalbital.It makes you jittery and shaky it can cause you to have a hard time falling asleep, staying asleep, or get a sleep it can also cause an increase in heart beat and uneven heart rhythm, It has many more side effect on bodies.Caffeine binds to the adenosine receptor and the cell can no longer identify adenosine because caffeine is taking up all the receptors that adenosine would normally bind to. Caffeine speeds up the nerve cell instead of slowing down like adenosine's effect, Caffeine causes the brain's blood vessels to constrict, because it blocks adenosine's ability to open it.This is why headache medicines contain caffeine ,by it constricting blood vessels in the brain can help stop a vascular

Ann Pietrangelo of Healthline.com lists these organs as the digestive and excretory system, circulatory and respiratory systems, skeletal and muscular systems, and the reproductive system. In the digestive and excretory systems, caffeine increases the acid in your stomach causing heartburn or upset stomach. Since it’s a diuretic, it tells your body to get rid of water. Nausea and vomiting can be triggered from caffeine withdraw. Caffeine overdose can cause excessive thirst, diarrhea, and increased urination. The circulatory and respiratory system can make your blood pressure go up. People with irregular heart rhythms, the caffeine can make the heart work harder than normal. Large amounts of caffeine consumption can interfere with absorption and metabolism of calcium. This can lead to osteoporosis. With the reproductive system, Pietrangelo points out that caffeine travels within the bloodstream and will cross into the placenta. This can cause a baby’s heart rate and metabolism to increase. Caffeine in large amounts can slow fetal growth and increase the risk of miscarriages. Painful lumps in the breast (fibrocystic disease) can also be a symptom of caffeine. Along with all the adverse side effects of caffeine, there are some health benefits when it’s taken in

There are many foods and drinks with caffeine found in them. For example, caffeine can be found in certain drinks such as, “Coffee, tea, caffeinated soda, and energy drinks. Some certain caffeinated soft drinks are Pepsi, Coca-Cola, Sunkist, and Mountain Dew. Also some energy drinks that caffeine may be found in are Redbull, Full Throttle, and Monster.” (Caffeine, para 2, 2015). Also, another example of sources of caffeine is that caffeine can be found in food, such as, “Caffeine is found in chocolate.” (Gavin, para 3, 2014). However, caffeine is not only in foods and drinks, it can also be found in medicines. For instance, Caffeine helps people with many medical issues, “Caffeine is sometimes consumed by many adults in order to kickstart medicine taken before hand. It improves the effect of many medications and is used for headaches or migraines.” (Bryant, para 21, 2015). In addition, caffeine can help a human with other things, “Caffeine that is treated with a citrate of potassium or sodium, can help breathing in premature babies. Also, it can help some children that suffer breathing problems, by helping them breath better.” (Bryant, para 20, 2015). So, basic sources of caffeine are coffee, tea, caffeinated soft drinks, chocolate, and

With that being said, someone who drinks four 6-oz cups of coffee takes in about 24 mg of caffeine, and someone who drinks eight 10-oz cups of coffee is already at 80 mg of caffeine. With that in mind, caffeine is found in many other products including beauty precuts, frozen desserts, gum, mints, pain relievers, nutrition bars, water, yogurt, and chocolate (10). Like I stated before, caffeine blocks the chemical adenosine in the brain preventing the brain from building this adenosine up to attach to its receptors, which is the chemical known to promote wakefulness, and the neurons in the brain continue to be stimulated, so it prevents you essentially from going into a sleepy mode. Now what changes when too much caffeine is part of this process? Besides the jitteriness and the nervousness caffeine may cause, it can also raise the amount of acid in your stomach and may cause heartburn or upset stomach. Not only does it raise the amount of acid, it also pushes your body to get rid of the water which makes it a diuretic. Extra caffeine doesn’t get stored in your body; it is processed in the liver and exits in your urine. Large doses of caffeine can cause you to lose too much water. Caffeine gets absorbed in the stomach and small intestine and then distributed throughout the

While low to moderate doses of caffeine do not include any of these negative side effects, as mentioned before it has the opposite effects. When caffeine is taken in doses higher than 250 mg it also may raise blood pressure and increase anxiety levels (Feeley 7). Not only will extremely high doses of caffeine cause unpleasant symptoms, but if taken in large amounts for a long period of time the consumer’s body will become dependent upon caffeine. Caffeine in definition is a drug and like any other drug the body will eventually become dependent upon it. Sudden removal of caffeine from the diet also cause displeasing symptoms like headaches, anxiety, vertigo, chills, muscle stiffness, and increased fatigue (Caffeine - Benefits and Risks) (Smith

It also negatively impacts the body’s sleep cycle. The half-life of one cup of coffee is six hours, this means if you have one cup at 4pm you will still have caffeine in your system at 10pm. This makes it hard to settle down and fall asleep. Even if you do manage to fall asleep it would be difficult to fall into that much needed deep sleep cycle. Which means
