Structurally, the chemical composition of caffeine is very similar to adenosine. Adenosine is the chemical component in our body that makes us feel sleepy. Therefore, when a person drinks coffee, caffeine binds to the neuroreceptors of adenosine. Thus, preventing them from feeling sleepy or tired. With regular and increase consumption of caffeine, our body starts to develop adenosine receptors in great quantities. Therefore, over time, one needs a higher dosage to remain awake.
