Caffeine is one of the most widely used chemicals today and one that is found in many foods and beverages. It is a stimulant that has both short and long term effects.
Some of the short term effects of caffeine are: acting as a nervous system stimulant, increasing blood pressure, decreasing levels of alertness, increasing body temperature, and blood flow to the heart. When consumed in high amounts, it can cause headaches, drowsiness, nausea, convulsions, seizures, fainting, coma, and death.
Effect Of Caffeine On Your Digestive System
Caffeine also affects the digestive system. It has a stimulatory effect on the liver, causing it to work harder to break down glucose and to store fat for use later. Caffeine can cause a phenomenon known as the “after-meal rebound,” wherein the blood sugar spikes caused by eating a meal are more pronounced.
Caffeine tends to keep you awake or “hang out” after you’ve had enough sleep. It can also produce more drowsiness and loss of memory. If you drive while being sleep deprived, you may become more prone to making mistakes, possibly because your mind is jumbled from a miserable night’s sleep.
While the short and long term effects of caffeine have been researched, studies have not been able to pinpoint its exact effects. Although many studies show caffeine to be somewhat addictive, most coffee users do not feel the effects at all.
But why does coffee act in such a strange way? It is theorized that caffeine acts by interacting with the central nervous system. To increase the concentration of adenosine, a chemical neurotransmitter. Adenosine is what causes feelings of pleasure when stimulated.
Lowers The Level Of Adenosine
Once the brain activates the brain, it begins to release adenosine. In a day, this level is usually lower than usual, but coffee allows the adenosine levels to get even smaller. The result is that the caffeine user begins to feel more stimulated also though they have not had the desired amount of caffeine, which may explain the occurrence of the after-meal rebound.
With all of these positive effects of caffeine, some believe that it is not all that bad. There are some benefits to be gained from drinking coffee, tea, soft drinks, and energy drinks.
There is no doubt that caffeine is very effective at keeping you awake during the morning. However, there are other benefits to be had from it. These benefits include increased alertness, higher energy levels, alertness in the later stages of the day. Improved focus, and a more energized feeling throughout the day.
For those that enjoy these effects, the adverse effects of coffee are a bonus. A diet low in coffee and high in antioxidants and other vitamins. And minerals can provide the benefits of coffee without all of the effects of caffeine.
Even those who do not enjoy the effects of coffee find that a regular diet. Full of these antioxidants and vitamins are a good alternative. It is also a good idea to avoid coffee and energy drinks if at all possible.
With all of the research available, it is hard to tell just how much coffee is safe for our bodies. And whether there are any severe health problems associated with coffee. This is why so many people are seeking the best sources of coffee, and the best sources of antioxidants.
