Does Caffeine Affects The Human 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.

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.

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.

Your brain can adapt to regular consumption of caffeine. If your adenosine receptors are perpetually clogged, your body will manufacture extra ones. That way, even with caffeine around, adenosine can still do its job of signaling the brain to power down. That’s why you may find you need to consume more and more caffeine to feel as alert: there are more and more adenosine receptors to block. It’s also why, if you suddenly quit caffeine, you may experience an unpleasant withdrawal. With plenty of receptors and no competition, adenosine can work overtime, causing symptoms like headaches, tiredness, and depression.

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.

The main reason people drink caffeine is to wake them up and keep them aware as well as to have a feeling of alertness. Too much caffeine can lead to anxiety, light headedness, and irritability. Caffeine can also affect you sleeping patterns. Another side effect of caffeine is increased heart rate. The caffeine that you take goes to work in your body within fifteen to forty five minutes. You will not feel its effects after 7.5 hours but can take up to 30 hours to get rid of it from your body. Caffeine is known to cause physical

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

Even though I do not possess a caffeine produced disease, I have experienced the consequences of drinking high amounts of caffeine which includes anxiety, insomnia, gastritis, colitis, mild tremors, and irritability. Although small quantities of caffeine may not substantially cause serious problems, if consumed in high quantities (>400mg.), it might worse the conditions of an anxiety disorder, diarrhea, bipolar disorder, bleeding disorders, heart conditions, diabetes, glaucoma, osteoporosis, epilepsy, irritable bowel syndrome, and high blood pressure (webmd, 2009). In addition to the consequences of caffeine mentioned above, new studies have linked caffeine to psychotic symptoms (Grimson, 2011). At the moment, I do not suffer any of the diseases previously mentioned, but I do have a family history of diabetes, depression, and anxiety disorders. Thus, the predisposition to any of the risks of a high caffeine intake increases. In summary, the consequences of consuming high doses of caffeine vary from person to person, and it may elicit different effects, which may range from a mild change of mood to a complex psychotic break; therefore I considered quitting caffeine an optimum choice for a healthier

All around the world, people drink coffee, tea and caffeinated drinks to wake up in the morning, to be more vigilant and alert throughout the day. Not only does this keep individuals alert but also allows them to focus and efficiently manage their time throughout their day. This quality of caffeine has caused it to be one of the most highly consumed psychoactive drugs. Individuals who require frequent intakes of Caffeine often feel tired, weak, drowsy if they tend to miss their cup of coffee early in the morning. Although, Caffeine is known for causing wakefulness and alertness it also has its downsides. If a person has a large dose of caffeine in a limited time, the drug could cause them trembling, anxiety and nausea. In long term effects,

Firstly, when drinking caffeinated drinks or anything that contains it the caffeine goes through the blood stream and directly to the brain. When we drink coffee, caffeine binds to our brain's adenosine receptors, stopping the chemical from binding with the receptors and making us tired. For the ones who regularly drink coffee in plentiful amounts, their brains develop more adenosine receptors, so it takes more coffee to keep us awake. That explains also why when we try to lay off the coffee a tad its very tiring to us because, were so use to that adenosine going to the brain. Whenever you’re awake, a chemical called adenosine slowly accumulates in your brain.

An increased intake of caffeine affects the body by sending signals for it to produce adrenaline, which gives the consumer a rush or alertness and energy.

Jenna has been using coffee in a large amount everyday (1 cup in the morning, one in the afternoon and two or more in the evening) therefore her body has build up a resistance to caffeine ingredient. As we know, caffeine binds to adenosine receptors to reduce drowsy feeling, however, after a while of using coffee, the brain of Jenna keep creating more and more adenosine receptors, which also means she will need more and more caffeine to keep her awake. Alex also uses coffee, but he does not use as much as Jenna and his brain has not develop much more adenosine receptors, therefore he only needs a limit amount of caffeine to keep him awake. Sally uses stress as her motivation instead of coffee, so she does not have a habit of using caffeine and her brain does not need caffeine to stay awake

One on the beneficial effects on caffeine, two the negative effects, and finally on trends in caffeine consumption

Caffeine does have many health benefits. It is a natural diuretic, which increases urine output, which flushes out toxins and excess fluid.

“Caffeine overdose can cause mania and anxiety, and can even lead to death” (Julian Cribb, 2014). Living in the present is full of hustle. Everyone has to race against the clock. Coffee has become a part of the breakfast menu, in order to eating breakfast fastest. The reason of drinking coffee every time for many people is fragrant smelling and mellow flavoring which make them feel perky and awake at work. They always understand that drinking coffee makes the brain more alert and awake (NUTRITION ARTICLES). But if you drink coffee too much, it would be harmful to your body. Many coffee drinkers are familiar with the symptoms "palpitation" that caused by coffee which is anxious that occurs when they drink coffee too much (NUTRITION ARTICLES). Coffee can raise blood pressure to those who suffer from high blood pressure already (Foster&Ted Kallmyer). Coffee may also cause anxiety and irritability, in some case with excessive drinking and some neurological symptoms. People who fond of drinking coffee and can't go without coffee should be aware of disadvantage of
