Is caffeine really bad for you?

What is caffeine and how does it work? 

Caffeine is a natural stimulant that can be found in coffee, cacao, and tea among others.

After consuming a dose of caffeine it is absorbed from the gastrointestinal tract within a short period of time. It makes its way to the liver where the caffeine is broken down into compounds, which then helps to stimulate our other organs. 

However, its main function takes place in the brain. It works by blocking the function of a neurotransmitter called Adenosine which basically signals your brain that it needs to relax. This neurotransmitter stimulates our sleep so that our body can preserve its energy. 

What caffeine does is that it blocks the effects of adenosine. This results in low chances of you being tired and weary. On top of that, caffeine can increase blood adrenaline levels that enhance brain activity keeping you alert and awake. The union of these two activities helps you stay focused and awakened.
