In the human body, caffeine acts as a stimulant for the central nervous system. It keeps us awake by blocking one of the body's sleep-inducing molecules, called adenosine.
Your body gets its supply of energy by breaking down ATP, a high-energy molecule. In the process, adenosine is released. When adenosine docks at the receptors in your brain, it activates a cascade of biochemical reactions that makes your neurons fire more slowly, making you get sleepy.
Caffeine interfears with this process of slowing your neurons.
