Effects of Caffeine Essay Effects of Caffeine Essay The debate on coffee is an age old one, which has been occurring now for centuries.

Caffeine is found in tea, cocoa, chocolate, and coffee.
The effects of caffeine on the nervous system derive from its interaction with the adenosine receptors at multiple sites in the brain. When adenosine binds to neural receptors, brain activity decreases, which causes the blood vessels to dilate and heart rate to slow down. Since caffeine is chemically similar to adenosine, caffeine binds to the same receptors that adenosine normally binds to.
As a result, caffeine blocks adenosine because the cell can no longer identify adenosine because the lack of available receptors. This increases brain activity, which boosts mental concentration and neuro-muscular movement and reduces sleep behavior and feelings of fatigue. This new activity stimulates the pituitary gland, which then produce hormones that notify the adrenal glands to release adrenaline, or epinephrine.
The influx of adrenaline notifies other parts of the body, such as the liver, to increase energy by releasing more amounts of sugar into the bloodstream.
By increasing adrenaline levels, caffeine also helps mobilize free fatty acids from fat and intramuscular triglycerides. Therefore, the effects of caffeine are greatly appealing to those with demanding lifestyles and workload, such as students and workers.
After identifying, participants were randomly given a placebo tablet or a mg of caffeine in a form of a pill.

Accordingly, they established their new proposition that in order to see improvements in memory, one needs to take at least mg of caffeine. In addition, caffeine also impacts the works of dopamine, a neurotransmitter, as a result of its blockade of adenosine receptors. Due to the fact that the prefrontal cortex is the main site involved with reward and addiction, caffeine can also encourage people to become physically and psychologically dependent on it.
Hence, excessive amounts of caffeine can result in withdrawal symptoms and caffeine intoxication. Withdrawal symptoms, include irritability and drowsiness, tend to appear to those who have stop consuming caffeine for two days following an average intake of mg daily.
On the other hand, studies show evidence that dopamine can protect brain cells from age and deterioration from disease. In addition, having an overdose in the amount of caffeine consumed can result in a state of caffeine intoxication, which is when the central nervous system is over-stimulated.
This situation typically occurs after one has consumed more than mg of caffeine in one sitting. The effects of caffeine intoxication heavily impact the nervous system.
