Caffeine and Adenosine Relationship

Adenosine is a byproduct of ATP, our body's energy source, and when it accumulates, it leads to drowsiness and a slowdown in the body. Caffeine obstructs adenosine from delivering messages to receptors that signal the body to rest, resulting in increased alertness and decreased drowsiness. Contrary to popular belief, caffeine does not directly provide energy, but it does enhance alertness and focus.
