If you want to understand what caffeine exactly dust your brain and your body, you will have to know that it is something that affects your sleep as well. The sensation of sleepiness usually comes in the brain and from a chemical known as adenosine. Unlike carbon dioxide, it is not flushed from the body, throughout the day. As the day goes on, these levels actually start building in your body and then you start feeling sleepy. When you sleep, these levels are finally removed from your system, and the cycle ends up repeating. Caffeine is actually able to have a very profound effect, because it is both water-soluble and soluble in fat as well. This usually allows it to cross easily from the bloodstream and completely into your brain. Once it is that, caffeine starts to work. The molecular structure of caffeine is very similar to adenosine. They actually have the very same shape. Because of this, once the caffeine is in your brain, it can actually bind with these receptors. Since the caffeine molecules are taking up all of the space, there is absolutely no room for the adenosine to bond.
Along with the above, caffeine also speeds of the release of energy from all of the fat cells. This will give you a lot of energy.

When the drink or food that you consume happens to hit your digestive system, it undergoes a lot of changes as well. It is broken down into other parts, and these parts can have additional effects on the entire body. The caffeine in the coffee is broken down into additional parts, and these have effects like releasing energy into the bloodstream, increasing heart rate and also increasing oxygen flow to the muscles and brain.
